30 Xdvi is a program for previewing dvi files, as produced e.g. by the
31 tex(1) program, under the X window system.
32
33 Xdvi can show the file shrunken by various integer factors, and it has
34 a ``magnifying glass'' for viewing parts of the page enlarged (see the
35 section MAGNIFIER below). This version of xdvi is also referred to as
36 xdvik since it uses the kpathsea library to locate and generate font
37 files. In addition to that, it supports the following features:
38
39 - hyperlinks in DVI files (section HYPERLINKS),
40
41 - direct rendering of PostScript<tm> Type 1 fonts (section TYPE 1
42 FONTS),
43
44 - source specials in the DVI file (section SOURCE SPECIALS),
45
46 - string search in DVI files (section STRING SEARCH),
47
48 - saving or printing (parts of) the DVI file (sections PRINT DIALOG
49 and SAVE DIALOG).
50
51 Xdvi can be compiled with the Motif toolkit or the Xaw (Athena) toolkit
52 (and variants of it), and the Motif version has a slightly different
53 GUI; these differences are noted below.
54
55 Before displaying a page of a DVI file, xdvi will check to see if the
56 file has changed since the last time it was displayed. If this is the
57 case, it will reload the file. This feature allows you to preview many
58 versions of the same file while running xdvi only once. Since it cannot
59 read partial DVI files, xdvik versions starting from 22.74.3 will cre‐
60 ate a temporary copy of the DVI file being viewed, to ensure that the
61 file can be viewed without interruptions. (The -notempfile can be used
62 to turn off this feature).
63
64 Xdvi can show PostScript<tm> specials by any of three methods. It will
65 try first to use Display PostScript<tm>, then NeWS, then it will try to
66 use Ghostscript to render the images. All of these options depend on
67 additional software to work properly; moreover, some of them may not be
68 compiled into this copy of xdvi.
69
70 For performance reasons, xdvi does not render PostScript specials in
71 the magnifying glass.
72
73 If no file name has been specified on the command line, xdvi will try
74 to open the most recently opened file; if the file history (accessible
75 via the File > Open Recent menu) is empty, or if none of the files in
76 the history are valid DVI files, it will pop up a file selector for
77 choosing a file name. (In previous versions, which didn't have a file
78 history, the file selector was always used; you can set the X resource
79 noFileArgUseHistory to false to get back the old behaviour.)
80
82 In addition to specifying the dvi file (with or without the .dvi exten‐
83 sion), xdvi supports the following command line options. If the option
84 begins with a `+' instead of a `-', the option is restored to its de‐
85 fault value. By default, these options can be set via the resource
86 names given in parentheses in the description of each option.
87
88 +page Specifies the first page to show. If + is given without a num‐
89 ber, the last page is assumed; the first page is the default.
90
91 -allowshell
92 (.allowShell) This option enables the shell escape in PostScript
93 specials. (For security reasons, shell escapes are disabled by
94 default.) This option should be rarely used; in particular it
95 should not be used just to uncompress files: that function is
96 done automatically if the file name ends in .Z, .gz, or .bz2.
97 Shell escapes are always turned off if the -safer option is
98 used.
99
100 -altfont font
101 (.altFont) Declares a default font to use when the font in the
102 dvi file cannot be found. This is useful, for example, with
103 PostScript <tm> fonts.
104
105 -anchorposition anchor
106 Jump to anchor after opening the DVI file. This is only useful
107 when invoking xdvi from other applications.
108
109 -background color
110 (.background) Determines the color of the background. Same as
111 -bg.
112
113 -bg color
114 (.background) Determines the color of the background.
115
116 -browser browser
117 (.wwwBrowser) Defines the web browser used for handling external
118 URLs. The value of this option or resource has the same syntax
119 as the BROWSER environment variable; see the explanation of that
120 variable in the section `ENVIRONMENT' below for a detailed de‐
121 scription. If neither the option nor the X resource wwwBrowser
122 is specified, the environment variables BROWSER and WWWBROWSER
123 (in that order) are used to determine the browser command. If
124 these are not set either, the following default value is used:
125 xdg-open %s:htmlview %s:firefox -remote -remote "openURL(%s,new-
126 window)":mozilla -remote "openURL(%s,new-window)":netscape
127 -raise -remote "openURL(%s,new-window)":xterm -e w3m %s:xterm -e
128 lynx %s:xterm -e wget %s
129
130 -copy (.copy) Always use the copy operation when writing characters to
131 the display. This option may be necessary for correct operation
132 on a color display, but overstrike characters will be incorrect.
133 If greyscale anti-aliasing is in use, the -copy operation will
134 disable the use of colorplanes and make overstrikes come out in‐
135 correctly. See also -thorough.
136
137 -cr color
138 (.cursorColor) Determines the color of the mouse cursor. The
139 default is the same as the foreground color.
140
141 -debug bitmask|string[,string ...]
142 (.debugLevel) If nonzero, prints additional information on stan‐
143 dard output. The argument can be either a bitmask specified as
144 a decimal number, or comma-separated list of strings.
145 For the bitmask representation, multiple values can be specified
146 by adding the numbers that represent the individual bits; e.g.
147 to debug all all file searching and opening commands, use 4032
148 (= 2048 + 1024 + 512 + 256 + 128 + 64). Use -1 to turn on debug‐
149 ging of everything (this will produce huge output).
150 For the string representation, use the strings listed in the
151 following table, with a comma to separate the values; e.g. to
152 debug all file searching and opening commands, use search,ex‐
153 pand,paths,hash,stat,open. (The option `kpathsea' is provided
154 as a shorthand for these.) Note that such a list may need to be
155 quoted to prevent the shell from interpreting commas or spaces
156 in the list.
157 The individual numbers and strings have the following meanings:
158
159 1 bitmap Bitmap creation
160 2 dvi DVI translation
161 4 pk PK fonts
162 8 batch Batch mode: Exit after
163 reading the DVI file
164 16 event Event handling
165 32 ps PostScript interpreter calls
166 64 stat Kpathsea stat(2) calls
167 128 hash Kpathsea hash table lookups
168 256 open Kpathsea file opening
169 512 paths Kpathsea path definitions
170 1024 expand Kpathsea path expansion
171 2048 search Kpathsea searching
172 4032 kpathsea All Kpathsea options
173 4096 htex Hypertex specials
174 8192 src Source specials
175 16384 client Client/server mode (see -unique
176 and -sourceposition options)
177 32768 ft FreeType library messages (Type 1 fonts)
178 65536 ft_verbose Verbose FreeType library messages (currently unused)
179 131072 gui GUI elements
180
181 Some of the Kpathsea debugging options are actually provided by
182 Kpathsea; see the Debugging section in the Kpathsea manual for
183 more information on these.
184
185 -density density
186 (.densityPercent) Determines the density used when shrinking
187 bitmaps for fonts. A higher value produces a lighter font. The
188 default value is 40. If greyscaling is in use, this argument
189 does not apply; use -gamma instead. See also the `S' keystroke.
190 Same as -S.
191
192 -display host:display
193 Specifies the host and screen to be used for displaying the dvi
194 file. By default this is obtained from the environment variable
195 DISPLAY.
196
197 -dvipspath path
198 (.dvipsPath) Use path as the dvips program to use when printing.
199 The default for this is dvips. The program or script should
200 read the DVI file from standard input, and write the PostScript
201 file to standard output.
202
203 -editor editor
204 (.editor) Specifies the editor that will be invoked when the
205 source-special() action is triggered to start a reverse search
206 (by default via Ctrl-Mouse 1). The argument to this option is a
207 format string in which occurrences of ``%f'' are replaced by the
208 file name, occurrences of ``%l'' are replaced by the line number
209 within the file, and optional occurrences of ``%c'' are replaced
210 by the column number within the line.
211
212 If neither the option nor the X resource .editor is specified,
213 the following environment variables are checked to determine the
214 editor command: XEDITOR, VISUAL, and EDITOR (in this sequence).
215 If the string is found as the value of the VISUAL or EDITOR en‐
216 vironment variables, then ``xterm -e '' is prepended to the
217 string; if the editor is specified by other means, then it must
218 be in the form of a shell command to pop up an X window with an
219 editor in it. If none of these variables is set, a warning mes‐
220 sage is displayed and the command ``xterm -e vi +%l %f'' is
221 used.
222
223 If no ``%f'' or ``%l'' occurs in the string, the missing format
224 strings are appended automatically. (This is for compatibility
225 with other programs when using one of the environment vari‐
226 ables).
227
228 A new instance of the editor is started each time this command
229 is used; therefore it is preferable to use an editor that can be
230 invoked in `client' mode to load new files into the same in‐
231 stance. Example settings are:
232
233 emacsclient --no-wait
234 (older Emacsen)
235
236 gnuclient -q
237 (XEmacs and newer Emacsen)
238
239 gvim --servername xdvi --remote
240 (VIM v6.0+; the `--servername xdvi' option will cause
241 gvim to run a dedicated instance for the files opened by
242 xdvi.)
243
244 nc (nedit)
245
246 Note that those strings need to be enclosed into quotes when us‐
247 ing them on the command-line to protect them from the shell;
248 when using them as argument for the .editor resource in an X re‐
249 source file, no quotes should be used.
250
251 NOTE ON SECURITY: The argument of this option isn't executed as
252 a shell command, but via exec() to prevent evil tricks with the
253 contents of source specials.
254
255 -expert
256 This option is only supported for backwards compatibility; it is
257 equivalent to -expertmode 0, which should be preferred.
258
259 -expertmode flag
260 (.expertMode) With an argument of 0, this option switches off
261 the display of the buttons, scrollbars, the toolbar (Motif on‐
262 ly), the statusline and the page list. These GUI elements can
263 also be (de)activated separately, by combining the appropriate
264 values in the flag argument. This acts similar to the -debug op‐
265 tion: The integer flag is treated as a bitmap where each bit
266 represents one element. If the bit has the value 1, the element
267 is switched on, if it has the value 0, the element is switched
268 off. The meaning of the bits is as follows:
269
270 1 statusline
271 2 scrollbars
272 4 Motif: pagelist, Xaw: buttons and pagelist
273 8 toolbar (Motif only)
274 16 menubar (Motif only)
275
276 For example, to turn on only the statusline and the scrollbars,
277 use 3 (= 1 + 2). See also the `x' keystroke, where the bits are
278 addressed by their positions, from 1 to 3 (Xaw) or 5 (Motif),
279 respectively.
280
281 If the statusline is not active, all messages that would normally be
282 printed to the statusline will be printed to stdout, unless the -hush‐
283 stdout option is used.
284
285 -fg color
286 (.foreground) Determines the color of the text (foreground).
287
288 -findstring string
289 This option triggers a search for string in the DVI file men‐
290 tioned on the command-line, similar to forward search (see the
291 description of the sourceposition option): If there is already
292 another instance of xdvi running on the displaying that DVI
293 file, it will cause that instance to perform the search instead.
294 The search starts at the top of the current page of the DVI
295 file.
296
297 -font font
298 (*font) Sets the font used in menus, buttons etc., as described
299 in the X(7x) man page. The font for child windows can be set
300 separately, e.g.:
301
302 xdvi*statusline*font: \
303 -*-helvetica-medium-r-*-*-12-*-*-*-*-*-*-*
304
305
306 -foreground color
307 Same as -fg.
308
309 -fullscreen
310 When this option is used, xdvi will (try to) run in fullscreen
311 mode, with no window decorations. This option is not guaranteed
312 to work with all windowmanagers/desktops; if you're experiencing
313 problems with it, please use the -geometry option instead, and a
314 suitable window manager setting to remove the window decora‐
315 tions. When using this option for presentations, you might want
316 to get rid of all the control widgets as well, using the -ex‐
317 pertmode option. This option can also be toggled at runtime us‐
318 ing the fullscreen action (by default bound to Ctrl-l).
319
320 -gamma gamma
321 (.gamma) Controls the interpolation of colors in the greyscale
322 anti-aliasing color palette. Default value is 1.0. For 0 <
323 gamma < 1, the fonts will be lighter (more like the background),
324 and for gamma > 1, the fonts will be darker (more like the fore‐
325 ground). Negative values behave the same way, but use a slight‐
326 ly different algorithm. For color and grayscale displays; for
327 monochrome, see -density. See also the `S' keystroke.
328
329 -geometry geometry
330 (.geometry) Specifies the initial geometry of the main window,
331 as described in the X(7x) man page. The geometry of child win‐
332 dows can be set separately, e.g.:
333 xdvi*helpwindow.geometry: 600x800
334
335 -gsalpha
336 (.gsAlpha) Causes Ghostscript to be called with the x11alpha
337 driver instead of the x11 driver. The x11alpha driver enables
338 anti-aliasing in PostScript specials, for a nicer appearance.
339 It is available on newer versions of Ghostscript. This option
340 can also be toggled with the `V' keystroke.
341
342 -gspalette palette
343 (.palette) Specifies the palette to be used when using Ghost‐
344 script for rendering PostScript specials. Possible values are
345 Color, Greyscale, and Monochrome. The default is Color.
346
347 -h, -help, --help
348 Prints a short help text with an overview of the command-line
349 options to standard output.
350
351 -hl color
352 (.highlight) Determines the color of the page border, of the
353 ruler in `ruler mode', and of the highlighting markers in for‐
354 ward search and string search. The default is the foreground
355 color.
356
357 -hush (.Hush) Causes xdvi to suppress all suppressible warnings.
358
359 -hushbell
360 (.hushBell) Don't sound the X bell when an error occurs.
361
362 -hushchars
363 (.hushLostChars) Causes xdvi to suppress warnings about refer‐
364 ences to characters which are not defined in the font.
365
366 -hushchecksums
367 (.hushChecksums) Causes xdvi to suppress warnings about checksum
368 mismatches between the dvi file and the font file.
369
370 -hushstdout
371 (.hushStdout) Suppresses printing of status messages to stdout.
372 Note that errors or warnings will still be printed to stderr
373 even if this option is used.
374
375 -icongeometry geometry
376 (.iconGeometry) Specifies the initial position for the icon.
377
378 -iconic
379 (.iconic) Causes the xdvi window to start in the iconic state.
380 The default is to start with the window open.
381
382 -install
383 (.install) If xdvi is running under a PseudoColor visual, then
384 (by default) it will check for TrueColor visuals with more bits
385 per pixel, and switch to such a visual if one exists. If no
386 such visual exists, it will use the current visual and colormap.
387 If -install is selected, however, it will still use a TrueColor
388 visual with a greater depth, if one is available; otherwise, it
389 will install its own colormap on the current visual. If the
390 current visual is not PseudoColor, then xdvi will not switch the
391 visual or colormap, regardless of its options. The default val‐
392 ue of the install resource is the special value, maybe. There
393 is no +install option. See also -noinstall, and the GREYSCALING
394 AND COLORMAPS section.
395
396 -interpreter filename
397 (.interpreter) Use filename as the Ghostscript interpreter. By
398 default it uses gs.
399
400 -keep (.keepPosition) Sets a flag to indicate that xdvi should not
401 move to the home position when moving to a new page. See also
402 the `k' keystroke. This flag is honored by all page switching
403 actions and by up-or-previous() / down-or-next(), although the
404 latter only honor the horizontal postion, not the vertical one.
405 This allows for a "continuous" scrolling back an forth through a
406 document with a display window narrower than a page width.
407
408 -l (.listFonts) List the names of all fonts used.
409
410 -license
411 Prints licensing information.
412
413 -linkcolor
414 (.linkColor) Color used for unvisited hyperlinks (`Blue2' by de‐
415 fault). Hyperlinks are unvisited before you click on them, or
416 after the DVI file has been reloaded. The value should be ei‐
417 ther a valid X color name (such as DarkGoldenrod4) or a hexadec‐
418 imal color string (such as #8b6508). See also -visitedlinkcolor
419 and -linkstyle.
420
421 -linkstyle
422 (.LinkStyle) Determines the style in which hyperlinks are dis‐
423 played. Possible values and their meanings are:
424
425 0 No highlighting of links
426 1 Underline links with link color
427 2 No underlining, color text with link color
428 3 Underline and display text colored with
429 link color
430
431 The values for link color are specified by the options/resources
432 -linkcolor and -visitedlinkcolor (which see).
433
434 -margins dimen
435 (.Margin) Specifies the size of both the top margin and side
436 margin. This determines the ``home'' position of the page with‐
437 in the window as follows. If the entire page fits in the win‐
438 dow, then the margin settings are ignored. If, even after re‐
439 moving the margins from the left, right, top, and bottom, the
440 page still cannot fit in the window, then the page is put in the
441 window such that the top and left margins are hidden, and pre‐
442 sumably the upper left-hand corner of the text on the page will
443 be in the upper left-hand corner of the window. Otherwise, the
444 text is centered in the window. The dimension should be a deci‐
445 mal number optionally followed by any of the two-letter abbrevi‐
446 ations for units accepted by TeX (pt, pc, in, bp, cm, mm, dd,
447 cc, or sp). By default, the unit will be cm (centimeters). See
448 also -sidemargin, -topmargin, and the keystroke `M.'
449
450 -mfmode mode-def
451 (.mfMode) Specifies a mode-def string, which can be used in
452 searching for fonts (see ENVIRONMENT, below). Generally, when
453 changing the mode-def, it is also necessary to change the font
454 size to the appropriate value for that mode. This is done by
455 adding a colon and the value in dots per inch; for example, -mf‐
456 mode ljfour:600. This method overrides any value given by the
457 pixelsPerInch resource or the -p command-line argument. The
458 metafont mode is also passed to metafont during automatic cre‐
459 ation of fonts. By default, it is unspecified.
460
461 -mgs size
462 Same as -mgs1.
463
464 -mgs[n] size
465 (.magnifierSize[n]) Specifies the size of the window to be used
466 for the ``magnifying glass'' for Button n. The size may be giv‐
467 en as an integer (indicating that the magnifying glass is to be
468 square), or it may be given in the form widthxheight. See the
469 MOUSE ACTIONS section. Defaults are 200x150, 400x250, 700x500,
470 1000x800, and 1200x1200.
471
472 -mousemode [0|1|2]
473 (.mouseMode) Specifies the default mode of xdvi at startup: Mag‐
474 nifier (0), Text Selection Mode (1) or Ruler Mode (2). See the
475 section MODES, below, for more information.
476
477 -nocolor
478 (.color) Turns off the use of color specials. This option can
479 be toggled with the `C' keystroke. (Note: -nocolor corresponds
480 to color:off; +nocolor to color:on.)
481
482 -nofork
483 (.fork) With the -sourceposition and -unique options, the de‐
484 fault behavior is for xdvi to put itself into the background
485 (like a daemon) if there is no appropriate instance of xdvi al‐
486 ready running. This argument makes it run in the foreground in‐
487 stead. This is useful for debugging, or if your client applica‐
488 tion cannot deal well with a program self-backgrounding itself
489 in this way -- e.g., the IPC functions in emacs are known to
490 have problems with this. If no -sourceposition or -unique argu‐
491 ment is given, then this option has no effect. (Note: -nofork
492 corresponds to fork:off; +nofork to fork:on.)
493
494 -noghostscript
495 (.ghostscript) Inhibits the use of Ghostscript for displaying
496 PostScript<tm> specials. (Note: -noghostscript corresponds to
497 ghostscript:off; +noghostscript to ghostscript:on.)
498
499 -nogrey
500 (.grey) Turns off the use of greyscale anti-aliasing when print‐
501 ing shrunken bitmaps. (Note: -nogrey corresponds to grey:off;
502 +nogrey to grey:on.) See also the `G' keystroke.
503
504 -nogssafer
505 (.gsSafer) Normally, if Ghostscript is used to render PostScript
506 specials, the Ghostscript interpreter is run with the option
507 -dSAFER. The -nogssafer option runs Ghostscript without
508 -dSAFER. The -dSAFER option in Ghostscript disables PostScript
509 operators such as deletefile, to prevent possibly malicious
510 PostScript programs from having any effect. If the -safer op‐
511 tion is specified, then this option has no effect; in that case
512 Ghostscript is always run with -dSAFER. (Note: -nogssafer cor‐
513 responds to gsSafer:off; +nogssafer to gsSafer:on.)
514
515 -noinstall
516 (.install) Inhibit the default behavior of switching to a True‐
517 Color visual if one is available with more bits per pixel than
518 the current visual. (Note: -noinstall corresponds install:off;
519 there is no +noinstall option.) See also -install, and the
520 GREYSCALING AND COLORMAPS section.
521
522 -nomakepk
523 (.makePk) Turns off automatic generation of font files that can‐
524 not be found by other means. (Note: -nomakepk corresponds to
525 makePk:off; +nomakepk to makePK:on.)
526
527 -nomatchinverted
528 (.matchInverted) Don't highlight string search matches in in‐
529 verted color; instead, draw a rectangle in highlight color (see
530 the -hl option) around the match. This option is activated auto‐
531 matically if the display isn't running in TrueColor. (Note:
532 -nomatchinverted corresponds to matchInverted:off; +nomatchin‐
533 verted to matchInverted:on.)
534
535 -noomega
536 (.omega) This will disable the use of Omega extensions when in‐
537 terpreting DVI files. By default, the additional opcodes 129
538 and 134 are recognized by xdvi as Omega extensions and inter‐
539 preted as requests to set 2-byte characters. The only drawback
540 is that the virtual font array will require 65536 positions in‐
541 stead of the default 256 positions, i.e. the memory requirements
542 of xdvi will be slightly larger. If you find this unacceptable
543 or encounter another problem with the Omega extensions, you can
544 switch this extension off by using -noomega (but please do send
545 a bug report if you find such problems - see the bug address in
546 the AUTHORS section below).
547 (Note: -noomega corresponds to omega: off; +noomega to omega:
548 on.)
549
550 -noscan
551 (.prescan) By default, xdvi does a preliminary scan of the dvi
552 file to process any papersize specials; this is especially im‐
553 portant at startup since the paper size may be needed to deter‐
554 mine the window size. If PostScript<tm> is in use, then pres‐
555 canning is also necessary in order to properly process header
556 files. In addition, prescanning is needed to correctly deter‐
557 mine the background color of a page. This option turns off such
558 prescanning. (Prescanning will be automatically be turned back
559 on if xdvi detects any of the specials mentioned above.) (Note:
560 -noscan corresponds to prescan:off; +noscan to prescan:on.)
561
562 -notempfile
563 (.tempFile) As mentioned in the section DESCRIPTION above, xdvi
564 will create a temporary copy of the DVI file so that it can be
565 accessed without interruptions even while the file is being
566 rewritten by TeX. Since this introduces the overhead of copying
567 the file every time it has changed, the -notempfile allows you
568 to turn off this behaviour. In this case, exposing parts of the
569 window while the DVI file is being written by TeX will erase the
570 current window contents until the DVI file can be completely
571 reread.
572 (Note: -notempfile corresponds to tempFile:off; +notempfile to
573 tempFile:on.)
574
575 -notype1fonts
576 (.type1) This will disable the use of the FreeType library to
577 display PostScript<tm> Type 1 fonts. Use this option as a work‐
578 around when you encounter problems with the display of Type 1
579 fonts (but please don't forget to send a bug report in this
580 case, to the URL mentioned in the section AUTHORS below).
581 (Note: -notype1fonts corresponds to type1:off; +notype1fonts to
582 type1:on.)
583
584 -offsets dimen
585 (.Offset) Specifies the size of both the horizontal and vertical
586 offsets of the output on the page. By decree of the Stanford
587 TeX Project, the default TeX page origin is always 1 inch over
588 and down from the top-left page corner, even when non-American
589 paper sizes are used. Therefore, the default offsets are 1.0
590 inch. The argument dimen should be a decimal number optionally
591 followed by any of the two-letter abbreviations for units ac‐
592 cepted by TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). By de‐
593 fault, the unit will be cm (centimeters). See also -xoffset and
594 -yoffset.
595
596 -p pixels
597 (.pixelsPerInch) Defines the size of the fonts to use, in pixels
598 per inch. The default value is 600. This option is provided
599 only for backwards compatibility; the preferred way is to set
600 both the resolution and the Metafont mode via the -mfmode option
601 (which see).
602
603 -paper papertype
604 (.paper) Specifies the size of the printed page. Note that in
605 most cases it's best to specify the paper size in the TeX input
606 file via the line
607
608 \usepackage[dvips]{geometry}
609
610 which will be recognized by both dvips and xdvi; in that case
611 the use of a `-paper' option should be unnecessary.
612 The paper size may be specified in the form widthxheight option‐
613 ally followed by a unit, where width and height are decimal num‐
614 bers giving the width and height of the paper, respectively, and
615 the unit is any of the two-letter abbreviations for units ac‐
616 cepted by TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). By de‐
617 fault, the unit is cm (centimeters).
618 There are also synonyms which may be used: us (8.5x11in), legal
619 (8.5x14in), foolscap (13.5x17in), as well as the ISO sizes
620 a1-a7, b1-b7, c1-c7. Each of these also has a landscape or `ro‐
621 tated' variant: usr (11x8.5in), a1r-a7r, etc. For compatibility
622 with dvips, the formats letter (8.5x11in), ledger (17x11in) and
623 tabloid [22m(11x17in) are also supported (these don't have rotated
624 variants).
625 Any of the above sizes may be preceded by a plus sign (`+');
626 this causes the paper size given here to override any paper size
627 given in the dvi file. The default paper size is 21 x 29.7 cm
628 (A4 size).
629
630 -pause (.pause) This option provides a simple implementation of incre‐
631 mental (stepwise) display, which can be used for presentations.
632 When this option is used, xdvi will pause the display of the
633 current page whenever it encounters a special special-string
634 (xdvi:pause by default; the string can be customized via -paus‐
635 especial, see below), and the cursor will change its shape. The
636 action unpause-or-next() (by default bound to the Space key)
637 will display the next portion of the page up to the following
638 special-string, or until the end of the page is reached. When
639 the option is not used, specials containing special-string will
640 be ignored.
641
642 -pausespecial special-string
643 (.pauseSpecial) Sets the special string that causes xdvi to
644 pause when the -pause option is active. The default value of
645 special-string is xdvi:pause.
646
647 -postscript flag
648 (.postscript) If flag = 0, rendering of PostScript<tm> specials
649 is disabled; instead, bounding boxes will be displayed (if
650 available). A value of 1 (the default) switches PostScript<tm>
651 specials on. With a value of 2, the PostScript<tm> specials are
652 displayed along with their bounding boxes; this allows you to
653 visually check the correctness of the bounding boxes. The values
654 can also be toggled at runtime with the `v' keystroke and the
655 corresponding numerical prefix arguments 0, 1 and 2.
656
657 -ps2pdfpath path
658 (.ps2pdfPath) Use path as a conversion program from PostScript
659 to PDF. The program or script should accept two command-line ar‐
660 guments: The PostScript file as first argument, and the PDF out‐
661 put file as second argument.
662
663 -rulecolor color
664 (.ruleColor) Determines the color of the rules used for the the
665 magnifier (default: foreground color).
666
667 -q (.noInitFile) Ignore the $HOME/.xdvirc startup file (i.e. don't
668 read it at startup, and don't write it at exit). This forces the
669 defaults defined in $HOME/.Xdefaults to be used. See FILES for
670 more information on $HOME/.xdvirc.
671
672 -rv (.reverseVideo) Causes the page to be displayed with white char‐
673 acters on a black background, instead of vice versa.
674
675 -S density
676 (.densityPercent) Same as -density (which see).
677
678 -s shrink
679 (.shrinkFactor) Defines the initial shrink factor. The default
680 value is 8. If shrink is given as 0, then the initial shrink
681 factor is computed so that the page fits within the window (as
682 if the `s' keystroke were given without a number).
683
684 -safer (.safer) This option turns on all available security options; it
685 is designed for use when xdvi is called by a browser that ob‐
686 tains a dvi or TeX file from another site. This option selects
687 +nogssafer and +allowshell.
688
689 -sidemargin dimen
690 (.sideMargin) Specifies the side margin (see -margins).
691
692 -sourceposition line[:col][ ]filename
693 This option makes xdvi search in the dvi file for the place cor‐
694 responding to the indicated line (and, optionally, column) in
695 the .tex source file, and highlight the place found by drawing a
696 rectangle in the highlight color (see the -hl option) around the
697 corresponding text. In addition, when run with this argument
698 (and the -nofork option is not given, which see), xdvi will al‐
699 ways return immediately: if it finds another instance of xdvi
700 already showing dvi_file, then it will cause that instance to
701 raise its window and move to the given place in the dvi file;
702 otherwise it will start up its own instance in the background.
703 If several instances of xdvi are displaying the respective dvi
704 file, the instance which was last raised to the foreground will
705 be used.
706
707 The space before filename is only needed if the filename starts
708 with a digit. When the space is used, the argument needs to be
709 enclosed in quotes to prevent the shell from misinterpreting the
710 space as argument separator.
711
712 This option requires that dvi_file be prepared with source spe‐
713 cial information. See the section on SOURCE SPECIALS for de‐
714 tails on how to do this.
715
716 Here is a more detailed description of how the filename in the
717 -sourceposition argument is matched with the filename in the
718 source specials:
719
720 1. If neither of the filenames contains a path name component,
721 the filenames are compared ignoring the `.tex' extensions in
722 both filenames.
723
724 2. Otherwise, if one of the filenames does contain a path compo‐
725 nent (e.g.: ./test.tex, ../test.tex, /my/homedir/tex/test.tex
726 or any combination of these), both filenames are expanded to
727 a full path, with any occurrences of ../ and ./ expanded, and
728 multiple slashes removed.
729 The pathname in the -sourceposition is expanded relative to
730 the current working directory of the xdvi -sourceposition in‐
731 vocation, and the pathnames in the source specials are ex‐
732 panded relative to the path of the current DVI file being
733 viewed.
734 The path names are then compared ignoring the `.tex' exten‐
735 sions in both path names.
736
737 -statusline
738 (.statusline) This option is obsolete; use -expertmode flag in‐
739 stead (which see).
740
741 -text-encoding encoding
742 (.textEncoding) Use encoding as the text encoding of the string
743 in the "Find" window. Usually, this should not be needed since
744 the encoding is determined from the locale settings.
745
746 -thorough
747 (.thorough) Xdvi will usually try to ensure that overstrike
748 characters (e.g., \notin) are printed correctly. On monochrome
749 displays, this is always possible with one logical operation,
750 either and or or. On color displays, however, this may take two
751 operations, one to set the appropriate bits and one to clear
752 other bits. If this is the case, then by default xdvi will in‐
753 stead use the copy operation, which does not handle overstriking
754 correctly. The -thorough option chooses the slower but more
755 correct choice. See also -copy.
756
757 -topmargin dimen
758 (.topMargin) Specifies the top and bottom margins (see -mar‐
759 gins).
760
761 -unique
762 (.unique) This option will make another instance of xdvi running
763 on the same display act as a `server'. For example, the invoca‐
764 tion
765
766 xdvi -unique +5 file.dvi
767
768 will cause this other instance to load file.dvi on page 5 in
769 place of the file that it is currently displaying. If there is
770 already another instance of xdvi already displaying the file
771 file.dvi, then it will just jump to page 5. If the other in‐
772 stance of xdvi is displaying a different file, it will load
773 file.dvi instead. Otherwise, if no other instance of xdvi is
774 currently running on the display, this option instead starts a
775 new instance of xdvi in the background (unless the -nofork op‐
776 tion is specified, which see) displaying page 5 of file.dvi.
777 The filename and the +n option for the page number are the only
778 options available for controlling a remote instance of xdvi like
779 this; all other options are currently ignored.
780
781 -useTeXpages
782 Use logical TeX pages (the values of the \count0 register) in‐
783 stead of physical pages for the pagelist labels and when jumping
784 to a page in a document with the `g' keystroke (or the goto-
785 page() action). This option can be toggled via the `T' key‐
786 stroke.
787
788 -version
789 Print information on the version of xdvi.
790
791 -visitedlinkcolor
792 (.visitedLinkColor) Color used for visited hyperlinks (`Purple4'
793 by default). Hyperlinks become visited once you click on them.
794 As for linkColor, the value should be either a valid X color
795 name or a hexadecimal color string.
796
797 -warnspecials
798 (.warnSpecials) Causes xdvi to print warnings about \special
799 strings that it cannot process to stderr. These warnings are
800 suppressed by default.
801
802 -watchfile n
803 (.watchFile) If this option is set to a value larger than 0, xd‐
804 vi will check the DVI file for changes every n seconds. If the
805 DVI file has been completely written by TeX, it will be reloaded
806 automatically. Fractional values (e.g. `2.5') are possible. The
807 default for this option is 0, i.e. no watching.
808 Since xdvi cannot handle partial DVI files, it tries not to
809 reload the file while it is being rewritten. However, use of
810 the magnifier or switching of pages requires reading (a part of)
811 the DVI file, and if the tempfile option is switched off, this
812 will erase the current contents of the window until the DVI file
813 can be read entirely.
814
815 -wheelunit pixels
816 (.wheelUnit) Sets the number of pixels that a motion of a wheel
817 mouse will move the image up, down, left, or right. (See the
818 wheel and hwheel actions, below, for more information on this.)
819 If set to zero, the wheel mouse functionality is (essentially)
820 disabled. The default value is 80.
821
822 -xoffset dimen
823 (.xOffset) Specifies the size of the horizontal offset of the
824 output on the page. See -offsets.
825
826 -yoffset dimen
827 (.yOffset) Specifies the size of the vertical offset of the out‐
828 put on the page. See -offsets.
829
831 Xdvi recognizes the following keystrokes when typed in its window.
832 Each may optionally be preceded by a (positive or negative) number, a
833 `prefix argument', whose interpretation will depend on the particular
834 keystroke. This prefix argument can be discarded by pressing the ``Es‐
835 cape'' key. If present, the ``Help'', ``Prior'' and ``Next'' keys are
836 synonyms for `?', `b', and `f' keys, respectively.
837
838 The key bindings listed here are those that xdvi assigns by default.
839 The names appearing in brackets at the beginning of the descriptions
840 are the names of the actions associated with the keys; these can be
841 used to customize the key bindings, as explained in more detail in the
842 section CUSTOMIZATION below. If only a lowercase binding is listed,
843 both upper- and lowercase keys will work for that binding.
844
845 ESC key
846 [discard-number()] The escape key discards the numerical prefix
847 for all actions (useful when you mistyped a number).
848
849 Return key
850 [forward-page()] Moves to the next page (or to the nth next page
851 if a number is given). Synonyms are `n', `f' and Line Feed.
852
853 Backspace key
854 [back-pagee()] Moves to the previous page (or back n pages).
855 Synonyms are `p', `b' and Ctrl-h.
856
857 Delete key
858 [up-or-previous()] Moves up two-thirds of a window-full, or to
859 the top of the previous page if already at the top of the page.
860 With a float argument, moves up the corresponding fraction of a
861 window-full.
862
863 Space key
864 [unpause-or-next()] Moves down two-thirds of a window-full, or
865 to the next page if already at the bottom of the page.
866 When the option -pause special-string is used and the display is
867 currently paused, this key will instead display the next portion
868 of the page until the next special-string or the end of the page
869 is encountered. See the description of the -pause option for
870 details. The action [down-or-next()] does a similar thing, but
871 without pausing; it is not bound to a key by default.
872
873 Ctrl-Home (Xaw), Ctrl-osfBeginLine (Motif)
874 [goto-page(1)] Moves to the first page of the document.
875
876 Ctrl-End (Xaw), Ctrl-osfEndLine (Motif)
877 [goto-page()] Moves to the last page of the document.
878
879 Home (Xaw), osfBeginLine (Motif)
880 [home-or-top()] Move to the ``home'' position of the page, or to
881 the top of the page if the keep flag is set (in this case, the
882 page doesn't scroll horizontally).
883
884 End (Xaw), osfEndLine (Motif)
885 [end-or-bottom()] Move to the ``end'' position of the page (the
886 lower right-hand corner), or to the bottom of the page if the
887 keep flag is set (in this case, the page doesn't scroll horizon‐
888 tally).
889
890 Down arrow
891 [down(0.015)] Scrolls page down.
892
893 Up arrow
894 [up(0.015)] Scrolls page up.
895
896 Right arrow
897 [right(0.015)] Scrolls page right.
898
899 Left arrow
900 [left(0.015)] Scrolls page left.
901
902 Alt-Ctrl-+
903 [change-density(25)] Increase the darkness of the fonts in the
904 DVI window by adding to the gamma value (see also the `S' key‐
905 stroke).
906
907 Alt-Ctrl--
908 [change-density(-25)] Decrease the darkness of the fonts in the
909 DVI window by subtracting from the gamma value (see also the `S'
910 keystroke).
911
912 Ctrl-+ [set-shrink-factor(+)] Increase the shrink factor (see also the
913 `s' keystroke).
914
915 Ctrl-- [set-shrink-factor(-)] Decrease the shrink factor (see also the
916 `s' keystroke).
917
918 Ctr-[ [pagehistory-delete-backward()] Delete the current item in the
919 page history and move to the history item before the deleted
920 one. With a prefix argument n, delete n previous history items.
921 See PAGE HISTORY for details.
922
923 [ [pagehistory-back()] Move back in the page history (see PAGE
924 HISTORY for details). With a prefix argument n, move back n his‐
925 tory items.
926
927 Ctr-] [pagehistory-delete-forward()] Delete the current item in the
928 page history and move to the history item after the deleted one.
929 With a prefix argument n, delete n next history items. See PAGE
930 HISTORY for details.
931
932 ] [pagehistory-forward()] Move forward in the page history (see
933 PAGE HISTORY for details). With a prefix argument n, move for‐
934 ward n history items.
935
936 ^ [home()] Move to the ``home'' position of the page. This is
937 normally the upper left-hand corner of the page, depending on
938 the margins as described in the -margins option, above.
939
940 ? [help()] Same as the h key (which see).
941
942 B [htex-back()] This key jumps back to the previous hyperlink an‐
943 chor. See the section HYPERLINKS for more information on navi‐
944 gating the links.
945
946 b [back-page()] Moves to the previous page (or back n pages).
947 Synonyms are `p', Ctrl-h and Backspace.
948
949 C [set-color()] This key toggles the use of color specials. The
950 key sequences `0C' and `1C' turn interpretation of color spe‐
951 cials off and on, respectively. See also the -nocolor option.
952
953 c [center()] Moves the page so that the point currently beneath
954 the mouse cursor is moved to the middle of the window, and warps
955 the mouse cursor to the same place.
956
957 D [toggle-grid-mode()] This key toggles the use of a grid on the
958 displayed page. If no number is given, the grid mode is
959 switched on or off. By prepending a number from 1 to 3, 3 dif‐
960 ferent grid levels can be set. The units of the grid are inches
961 or centimeters, depending on whether the paper format is letter
962 (in) or a4 (cm).
963
964 d [down()] Moves page down two thirds of a window-full. With a
965 float argument to ``down'', moves down the corresponding frac‐
966 tion of a window-full.
967
968 Ctrl-f [find()] Pop up a window to search for a string in the DVI file.
969 See the section STRING SEARCH, below, for more details.
970
971 f [forward-page()] Moves to the next page (or to the nth next page
972 if a number is given). Synonyms are `n', Return, and Line Feed.
973
974 G [set-greyscaling()] This key toggles the use of greyscale anti-
975 aliasing for displaying shrunken bitmaps. In addition, the key
976 sequences `0G' and `1G' clear and set this flag, respectively.
977 See also the -nogrey option.
978
979 If given a numeric argument that is not 0 or 1, greyscale anti-
980 aliasing is turned on, and the gamma resource is set to the val‐
981 ue divided by 100. E.g., `150G' turns on greyscale and sets gam‐
982 ma to 1.5.
983
984 Ctrl-g [find-next()] Find the next match string in the DVI file; this
985 can be used instead of pressing the `Find' button in the search
986 window.
987
988 g [goto-page()] Moves to the page with the given number. If no
989 page number is given, xdvi jumps to the last page.
990 If the option/resource useTeXpages is active, the numbers corre‐
991 spond to the actual page numbers in the TeX file; otherwise, ab‐
992 solute page numbers (starting from 1) are used. In the latter
993 case, the page numbers can be changed with the `P' keystroke,
994 below. Note that with the useTeXpages option it is possible
995 that the same page number occurs multiple times; in such a case,
996 xdvi will use the first page number that matches.
997
998 h Pops up a help window with a short explanation of the most im‐
999 portant key bindings and concepts.
1000
1001 k [set-keep-flag()] Normally when xdvi switches pages, it moves to
1002 the home position as well. The `k' keystroke toggles a `keep-
1003 position' flag which, when set, will keep the same position when
1004 moving between pages. Also `0k' and `1k' clear and set this
1005 flag, respectively. See also the -keep option.
1006
1007 Ctrl-l [fullscreen(toggle)] Toggles fullscreen mode (see the descrip‐
1008 tion of the -fullscreen option for more information on this).
1009 This is even more flaky than using the command-line option:
1010 There is no universal standard how a window could change its own
1011 geometry or window decorations at run-time, so this will not
1012 work with most window managers or desktops. Generally, it's bet‐
1013 ter to use the window manager controls to change the size or
1014 decorations of the xdvi window.
1015
1016 l [left()] Moves page left two thirds of a window-full.
1017
1018 M [set-margins()] Sets the margins so that the point currently un‐
1019 der the mouse cursor defines the upper left-hand corner of the
1020 text in the page. Note that the command does not move the im‐
1021 age, but only determines the margins for the page switching com‐
1022 mands. For details on how the margins are used, see the -margins
1023 option.
1024
1025 m [toggle-mark()] Toggles the mark for the current page in the
1026 page list. When a page is marked, it is displayed with a small
1027 star `*' next to the page number. The marked pages can then be
1028 printed or saved to a file. A page or several pages can also be
1029 marked by clicking or dragging Mouse-2 in the page list.
1030
1031 Ctrl-n [toggle-mark()forward-page()] Toggles the mark for the current
1032 page in the page list, and moves to the next page. This lets you
1033 quickly mark a series of subsequent pages.
1034
1035 n [forward-page()] Moves to the next page (or to the nth next page
1036 if a number is given). Synonyms are `f', Return, and Line Feed.
1037
1038 Ctrl-o [select-dvi-file()] Read a new dvi file. A file-selection widget
1039 is popped up for you to choose the DVI file from. If a prefix
1040 argument n is given, the n th file from the file history is
1041 opened instead.
1042
1043 P [declare-page-number()] ``This is page number n.'' This can be
1044 used to make the `g' keystroke refer to a different page number
1045 than the physical page. (If you want to use `logical' or TeX
1046 page numbers instead of physical pages, consider using the op‐
1047 tion -useTeXpages instead.) The argument n should be given as
1048 prefix to this key.
1049
1050 Ctrl-p [print()] Opens a popup window for printing the DVI file, or
1051 parts of it. See the section PRINT DIALOG for an explanation of
1052 the options available, and the resources to customize the de‐
1053 fault behaviour.
1054
1055 p [back-page()] Moves to the previous page (or back n pages).
1056 Synonyms are `b', Ctrl-h and Backspace.
1057
1058 q [quit()] Quits the program.
1059
1060 Ctrl-r [forward-page(0)] Redisplays the current page.
1061
1062 R [reread-dvi-file()] Forces the dvi file to be reread. This al‐
1063 lows you to preview many versions of the same file while running
1064 xdvi only once.
1065
1066 r [right()] Moves page right two thirds of a window-full.
1067
1068 Ctrl-s [save()] Opens a popup window for saving the DVI file, or parts
1069 of it. See the section SAVE DIALOG below for more information on
1070 this.
1071
1072 S [set-density()] Sets the density factor to be used when shrink‐
1073 ing bitmaps. This should be a number between 0 and 100; higher
1074 numbers produce lighter characters. If greyscaling mode is in
1075 effect, this changes the value of gamma instead. The new value
1076 of gamma is the given number divided by 100; negative values are
1077 allowed.
1078
1079 s [set-shrink-factor()] Changes the shrink factor to the given
1080 number. If no number is given, the smallest factor that makes
1081 the entire page fit in the window will be used. (Margins are
1082 ignored in this computation.)
1083
1084 T [use-tex-pages()] Use logical TeX pages (the values of the
1085 \count0 register) instead of physical pages for the pagelist la‐
1086 bels and when jumping to a page in a document via goto-page().
1087 See also the -useTeXpages option.
1088
1089 t [switch-magnifier-units()] Switches the units used for the mag‐
1090 nifier tick marks, and for reporting the distance between the
1091 mouse pointer and the ruler centre in ruler mode (see the sec‐
1092 tion MODES). The default value is specified by the X resource
1093 tickUnits (`mm' by default). The units toggle through the fol‐
1094 lowing values; except for `px', they all correspond to TeX's
1095 units: mm (millimeters) pt (TeX points), in (inches), sp (scaled
1096 points, the unit used internally by TeX) bp (big points or
1097 `PostScript points'), cc (cicero points), dd (didot points), pc
1098 (pica), and px (screen pixels).
1099
1100 Ctrl-u [back-page()toggle-mark()] Moves to the previous page, and tog‐
1101 gles the mark for that page. This is the dual action to Ctrl-n.
1102
1103 u [up()] Moves page up two thirds of a window-full. With a float
1104 argument to ``up'', moves up the corresponding fraction of a
1105 window-full.
1106
1107 Ctrl-v [show-source-specials()] Show bounding boxes for every source
1108 special on the current page, and print the strings contained in
1109 these specials to stderr. With prefix 1, show every bounding box
1110 on the page. This is for debugging purposes mainly.
1111
1112 V [set-gs-alpha()] This key toggles the anti-aliasing of Post‐
1113 Script<tm> specials when Ghostscript is used as renderer. In
1114 addition the key sequences `0V' and `1V' clear and set this
1115 flag, respectively. See also the -gsalpha option.
1116
1117 v [set-ps()] This key toggles the rendering of PostScript<tm> spe‐
1118 cials between 3 states:
1119
1120 - specials (like EPS graphics) are displayed;
1121
1122 - specials are displayed along with their bounding box (if
1123 available);
1124
1125 - only the bounding box is displayed.
1126
1127 The states can also be selected directly by using `1v', `2v' and
1128 `0v' respectively. See also the -postscript option.
1129
1130 Ctrl-x [source-what-special()] Display information about the source
1131 special next to the mouse cursor in the statusline. This is the
1132 same special that would be found by source-special(), but with‐
1133 out invoking the editor. For debugging purposes.
1134
1135 x [set-expert-mode()] Toggles expert mode, in which the sta‐
1136 tusline, the scrollbars, the menu buttons, the toolbar (Motif
1137 only) and the page list are not shown. Typing `1x' toggles the
1138 display of the statusline at the bottom of the window. Typing
1139 `2x' toggles the scrollbars (if available). For Xaw, `3x' tog‐
1140 gles the menu buttons and the page list, for Motif, it toggles
1141 the page list. In Motif, the additional bindings `4x' toggle the
1142 toolbar, and `5x' the menu bar.
1143 Without a prefix argument, all of the mentioned GUI elements are
1144 either switched on (if they had been invisible before) or off.
1145 Toggling the scrollbars may behave erratically with the Xaw wid‐
1146 gets; e.g. the scrollbars may reappear after resizing the win‐
1147 dow, and at certain window sizes one of the scrollbars may fail
1148 to disappear.
1149 See also the option -expertmode (the numbers above correspond to
1150 the bits in the argument to -expertmode).
1151
1153 The mouse actions can be customized by setting the X resource mouse‐
1154 Translations. Since there are three different mouse modes (see the
1155 section MODES below), there is a special action mouse-modes which lists
1156 the actions for each of the three modes: mouse-modes("ACTIONS-FOR-
1157 MODE1", "ACTIONS-FOR-MODE2", "ACTIONS-FOR-MODE3"). If only one argu‐
1158 ment is specified, this action is used for all modes. The default
1159 bindings are as follows:
1160
1161 xdvi.mouseTranslations: \
1162 Shift<Btn1Down>:mouse-modes("drag(+)")\n\
1163 Shift<Btn2Down>:mouse-modes("drag(|)")\n\
1164 Shift<Btn3Down>:mouse-modes("drag(-)")\n\
1165 Ctrl<Btn1Down>:mouse-modes("source-special()")\n\
1166 <Btn1Down>: mouse-modes("do-href()magnifier(*2)", "text-selection()", "ruler()")\n\
1167 <Btn2Down>: mouse-modes("do-href-newwindow()magnifier(*2)", "text-selection()", "ruler()")\n\
1168 <Btn3Down>: mouse-modes("magnifier(*3)")\n\
1169 <Btn4Down>: mouse-modes("wheel(-0.2)")\n\
1170 <Btn5Down>: mouse-modes("wheel(0.2)")\n\
1171 <Btn6Down>: mouse-modes("hwheel(-0.2)")\n\
1172 <Btn7Down>: mouse-modes("hwheel(0.2)")\n\
1173
1174 All of these actions are described in more detail below. Note the use
1175 of quote symbols around the action strings, which are necessary to
1176 group them into one argument. Buttons 4, 5, 6, and 7 refer to wheel
1177 movements (wheel up/down/left/right) on wheel mice. Not all mice sup‐
1178 port horizontal scrolling.
1179
1180 The X Toolkit routines that implement translations do not support event
1181 types of Btn6Down or Btn7Down. Because of this, xdvi implements its
1182 own parser for translations given in mouseTranslations. This parser is
1183 more limited than the parser built in to the X Toolkit. The string
1184 given in mouseTranslations should not begin with ``#replace'', ``#aug‐
1185 ment'', or ``#override''. Modifiers of the form @keysym are not sup‐
1186 ported, and the event type must be of the form BtnDown or BtnnDown,
1187 where n is a positive integer without leading zeroes. Also, some limi‐
1188 tations apply to the action field.
1189
1190 do-href()
1191
1192 do-href-newwindow()
1193 Usually, if a binding specifies more then one action, all ac‐
1194 tions are executed in a sequence. The hyperlink bindings do-
1195 href() and do-href-newwindow() are special in that they are used
1196 as an alternative to other actions that might follow them if the
1197 mouse is currently located on a hyperlink. In this case, none
1198 of the other actions will be executed; otherwise, only the other
1199 actions are executed.
1200 The action do-href() jumps to the link target in the current xd‐
1201 vi window (eventually switching to another page), and do-href-
1202 newwindow() opens a new instance of xdvi for the link target.
1203 In both cases, the location of the target is indicated by a
1204 small arrow drawn in the same color as a visited link in the
1205 left corner of the window.
1206
1207 magnifier(n x m)
1208
1209 magnifier(*n)
1210 This action will pop up a ``magnifying glass'' which shows the
1211 unshrunk image of the region around the mouse pointer. The mag‐
1212 nifier disappears when the mouse button is released. Moving the
1213 mouse cursor while holding the button down will move the magni‐
1214 fier.
1215 Different mouse buttons produce different sized windows, as in‐
1216 dicated by the the argument of the magnifier() action. Its argu‐
1217 ment is either a string of the form widthxheight, as in the
1218 -mgsn command-line option, or one of the strings *1 through *5,
1219 referring to the value specified by the corresponding -mgsn op‐
1220 tion.
1221
1222 drag(+)
1223
1224 drag(|)
1225
1226 drag(-)
1227 Drags the page with the mouse. This action should have one pa‐
1228 rameter, the character ``|'', ``-'', or ``+'', indicating verti‐
1229 cal dragging only, horizontal dragging only, or dragging in all
1230 directions.
1231
1232 source-special()
1233 This action starts a ``reverse search'', opening the editor at
1234 the location in the TeX file corresponding to the pointer loca‐
1235 tion in the DVI file. See the section on SOURCE SPECIALS, be‐
1236 low, for more information on this.
1237
1238 wheel()
1239 This action can be used to scroll the image with a wheel mouse,
1240 where it is usually bound to mouse button 4 (wheel up) or 5
1241 (wheel down). The action takes one parameter, giving the dis‐
1242 tance to scroll the image. If the parameter contains a decimal
1243 point, the distance is given in wheel units; otherwise, pixels.
1244 A negative value scrolls up, a positive value scrolls down.
1245
1246 hwheel()
1247 This action can be used to scroll the image horizontally with a
1248 wheel mouse, where it is usually bound to mouse button 6 (wheel
1249 left) or 7 (wheel right). The action takes one parameter, giv‐
1250 ing the distance to scroll the image. If the parameter contains
1251 a decimal point, the distance is given in wheel units; other‐
1252 wise, pixels. A negative value scrolls left, a positive value
1253 scrolls right. Not all mice support horizontal scrolling; this
1254 is mostly for touchpads, trackpads, etc.
1255
1256 text-selection()
1257 This action allows you to mark a rectangular region of text in
1258 the DVI file. The text is put into the X selection buffer and
1259 can be pasted into other applictions (e.g. text editors). This
1260 works similar to the Plain text option in the Save dialog; see
1261 the discussion there for more information on encoding issues.
1262
1263 ruler()
1264 This action creates a cross-shaped ruler. Moving the mouse and
1265 holding the button down drags the ruler and lets you measure
1266 distances on the page. See the section Ruler Mode for more in‐
1267 formation on this.
1268
1270 The following actions are not bound to a key by default, but are avail‐
1271 able for customization.
1272
1273 quit-confirm()
1274 Pops up a confirmation window to quit xdvi. To bind it to the
1275 `q' key instead of the default `quit()' action, put the follow‐
1276 ing into your ~/.Xdefaults file:
1277
1278 xdvi.mainTranslations: #override\
1279 <Key>q: quit-confirm()\n
1280
1281 down-or-next()
1282 Similar to unpause-or-next(): Moves down two-thirds of a window-
1283 full, or to the next page if already at the bottom of the page.
1284
1285 shrink-to-dpi()
1286 This action takes one (required) argument. It sets the shrink
1287 factor to an integer so as to approximate the use of fonts with
1288 the corresponding number of dots per inch. If xdvi is using
1289 fonts scaled for p dots per inch, and the argument to shrink-to-
1290 dpi is n, then the corresponding shrink factor is the ratio p/n,
1291 rounded to the nearest integer.
1292
1293 user-exec()
1294 This action takes one (required) argument. Runs an external pro‐
1295 gram specified by the argument, which is tokenized on white‐
1296 space. The XDVI_FILE environment variable is set to the absolute
1297 pathname of the DVI file, so that the program can find the DVI.
1298 As an example, to establish the key `m' as a keybinding that re‐
1299 generates the DVI file with `make', put the following into your
1300 ~/.Xdefaults file:
1301
1302 xdvi.mainTranslations: #override\
1303 <Key>m: user-exec(xdvi-remake)\n
1304
1305 where `xdvi-remake' names a program in your PATH analogous to
1306 `cd $(dirname $XDVI_FILE) && make $(basename $XDVI_FILE)'. (See
1307 also the section SIGNALS for a way to get xdvi to reload the DVI
1308 file once it has been regenerated.)
1309
1311 Key and mouse button assignments can be changed by setting the main‐
1312 Translations resource to a string of translations as defined in the
1313 documentation for the X toolkit. The actions should take the form of
1314 action names listed in the KEYSTROKES and MOUSE ACTIONS sections.
1315
1316 An exception to this are the Motif keys osfPageUp (PgUp), osfPageDown
1317 (PgDown), osfBeginLine (Home) and osfEndLine (End) which are currently
1318 not customizable in the Motif version.
1319
1320 Key actions will usually be without arguments; if they are passed an
1321 argument, it represents the optional number or `prefix argument' typed
1322 prior to the action.
1323
1324 Some key actions may take special arguments, as follows: The argument
1325 of goto-page may be the letter `e', indicating the action of going to
1326 the end of the document. The argument of set-shrink-factor may be the
1327 letter `a', indicating that the shrink factor should be set to the
1328 smallest value such that the page will fit in the window, or one of the
1329 signs `+' or `-', indicating that the shrink factor should be increased
1330 or decreased, respectively. Finally, actions that would perform a tog‐
1331 gle, such as set-keep-flag, may receive an argument `t', indicating
1332 that the action should toggle regardless of the current prefix argu‐
1333 ment.
1334
1335 Mouse actions should refer only to ButtonPress events (e.g.,
1336 <Btn1Down>:magnifier(*1)). The corresponding motion and release events
1337 will be handled internally. A key action may be bound to a mouse
1338 event, but not vice versa.
1339
1340 Usually the string of translations should begin with ``#override'', in‐
1341 dicating that the default key and mouse button assignments should not
1342 be discarded.
1343
1344 When keys or mouse buttons involving modifiers (such as Ctrl or Shift)
1345 are customized together with their non-modified equivalents, the modi‐
1346 fied keys should come first, for example:
1347
1348 xdvi.mainTranslations: #override \
1349 Shift<Key>s: select-dvi-file()\n\
1350 Ctrl<Key>s: save()\n\
1351 <Key>s: find()\n
1352
1353
1354 Because xdvi needs to capture pointer motion events, and because the X
1355 Toolkit translations mechanism cannot accommodate both motion events
1356 and double-click events at the same time, it is not possible to specify
1357 double-click actions in xdvi customizations. For information on this
1358 and other aspects of translations, see the X Toolkit Intrinsics docu‐
1359 mentation.
1360
1361 There is no command-line option to set the mainTranslations resource,
1362 since changing this resource on the command line would be cumbersome.
1363 To set the resource for testing purposes, use the -xrm command-line op‐
1364 tion provided by the X toolkit. For example, xdvi -xrm 'XDvi.main‐
1365 Translations: #override "z":quit()' ... or xdvi -xrm 'XDvi.mainTrans‐
1366 lations: #override <Key>z:quit()' ... will cause the key `z' to quit
1367 xdvi.
1368
1369 Some resources are provided to allow customization of the geometry of
1370 the Xaw command buttons. Again, they are not changeable via command-
1371 line options, other than via the -xrm option. All of these resources
1372 take integer values.
1373
1374 buttonSideSpacing
1375 The number of pixels to be placed on either side of the buttons.
1376 The default value is 6.
1377
1378 buttonTopSpacing
1379 The number of pixels between the top button and the top of the
1380 window. The default value is 50.
1381
1382 buttonBetweenSpacing
1383 The number of pixels between the buttons. The default value is
1384 20.
1385
1386 buttonBetweenExtra
1387 The number of pixels of additional space to be inserted if the
1388 buttonTranslations resource string contains an extra newline
1389 character. The default value is 50.
1390
1391 buttonBorderWidth
1392 The border width of the button windows. The default value is 1.
1393
1395 The scrollable page list on the right of the main window allows you to
1396 jump directly to a page in the DVI file.
1397
1398 Mouse-1
1399 Jumps to the page the mouse is located on.
1400
1401 Mouse-2
1402 [toggle-mark()] Toggle the mark of the current page. The marks
1403 are used by the `Print' and `Save to file' dialogs to select on‐
1404 ly marked pages from the DVI file.
1405
1406 When the mouse pointer is inside the page list, the mouse wheel switch‐
1407 es to the next or previous page.
1408
1410 The scrollbars (if present) behave in the standard way: pushing Button
1411 2 in a scrollbar moves the top or left edge of the scrollbar to that
1412 point and optionally drags it; pushing Button 1 moves the image up or
1413 right by an amount equal to the distance from the button press to the
1414 upper left-hand corner of the window; pushing Button 3 moves the image
1415 down or left by the same amount.
1416
1417 The scrollbars can be removed via the -expertmode flag/keystroke (which
1418 see).
1419
1421 By default, the mouse buttons 1 to 5 will pop up a ``magnifying glass''
1422 that shows an unshrunken image of the page (i.e. an image at the reso‐
1423 lution determined by the option/X resource pixels or mfmode) at varying
1424 sizes. When the magnifier is moved, small ruler-like tick marks are
1425 displayed at the edges of the magnifier (unless the X resource de‐
1426 layRulers is set to false, in which case the tick marks will always be
1427 displayed). The unit of the marks is determined by the X resource
1428 tickUnits (mm by default). This unit can be changed at runtime via the
1429 action switch-magnifier-units(), by default bound to the keystroke `t'
1430 (see the description of that key, and of switch-magnifier-units() for
1431 more details on the units available).
1432 The length of the tick marks can be changed via the X resource tick‐
1433 Length (4 by default). A zero or negative value suppresses the tick
1434 marks.
1435
1437 Xdvi keeps a history of viewed pages, and you can move through the his‐
1438 tory and delete items using the keys [ (pagehistory-back()), ] (page‐
1439 history-forward()), Ctr-[ (pagehistory-delete-backward()) and Ctr-]
1440 (pagehistory-delete-forward()).
1441
1442 When one of the history commands is used, the page history is displayed
1443 in the status line at the bottom of the window, with the current list
1444 item marked by square brackets `[', `]' and a left and right context of
1445 at most 10 items. File boundaries are marked by `#'.
1446
1447 The size of the history can be customized with the X resource pageHis‐
1448 torySize (the default size is 1000 items). If the size is set to 0, the
1449 history commands are disabled.
1450
1452 The actions do-href() and do-href-newwindow() (by default bound to
1453 Mouse-1 and Mouse-2 if the pointer is currently located on a hyperlink)
1454 can be used to open the link target in the same window (do-href()) or
1455 in a new window (do-href-newwindow()).
1456
1457 If the link target is not a file on the local disk, xdvi tries to
1458 launch a web browser (as specified by the -browser command line option,
1459 the BROWSER environment variable or the wwwBrowser X resource, in this
1460 order) to retrieve the document. See the description of the BROWSER en‐
1461 vironment variable, below, for an example setting.
1462
1463 If the file is a local file, xdvi tries to determine if it is a DVI
1464 file. If it is, xdvi will try to display the file; otherwise it will
1465 try to determine the MIME type of the file, and from that an applica‐
1466 tion suitable for opening the file. This is done by parsing the files
1467 specified by the environment variable EXTENSIONMAPS for a mapping of
1468 filename extensions to MIME types, and the files determined by the en‐
1469 vironment variable MAILCAPS for a mapping of MIME types to application
1470 programs. See the descriptions of these variables in the section ENVI‐
1471 RONMENT, below, for a more detailed description and the default values
1472 of these variables. If no suitable files are found, a set of built-in
1473 default MIME types and applications is used.
1474
1475 Xdvi currently uses no heuristics apart from the filename suffix to de‐
1476 termine the mime type of a file. If a filename has no suffix, the value
1477 of the resource noMimeSuffix is used (by default application/x-un‐
1478 known). If the suffix doesn't match any of the suffixes in mime.types,
1479 the value of the resource unknownMimeSuffix is used (by default appli‐
1480 cation/x-unknown). If the mailcap entries do not list a viewer for a
1481 given mime type, xdvi will show a warning popup. If you want to avoid
1482 this warning, and for example want to always use the netscape browser
1483 for unknown MIME types, you could add the following line to your
1484 ~/.mailcap file:
1485
1486 application/xdvi-unknown; \
1487 netscape -raise -remote 'openURL(%s,new-window)'

1489
1491 The keystroke Ctrl-f or the menu entry File > Find ... (or the `Binoc‐
1492 ulars' symbol in the toolbar, for Motif) opens a dialog window to
1493 search for a text string or a regular expression in the DVI file. The
1494 keystroke Ctrl-g jumps to the next match (like pressing the `Find' but‐
1495 ton in the search window).
1496
1497 By default, the matches are highlighted in inverted color. If the dis‐
1498 play isn't running in TrueColor, or if the X resource matchHighlightIn‐
1499 verted is set to false or the command-line option -nomatchinverted is
1500 used, xdvi will instead draw a rectangle in highlight color (see the
1501 -hl option) around the match.
1502
1503 If a match crosses a page boundary, only the part on the first page is
1504 highlighted. Xdvi will scan up to 2 adjacent pages to match strings
1505 crossing page boundaries; but note that header or footer lines, or in‐
1506 tervening float pages will be treated as parts of the scanned text.
1507 Such text will usually cause multi-page matching to fail.
1508
1509 This emphasizes the fact that searching in the formatted text (the DVI
1510 output) works differently from searching in the source text: Searching
1511 in the DVI file makes it easier to skip formatting instructions, and
1512 makes it possible to search for e.g. hyphenation and equation numbers;
1513 but sometimes the formatting results can also get in the way, e.g. in
1514 the case of footnotes. In these cases it's better to search in the TeX
1515 source instead. The use of source specials will make switching between
1516 the xdvi display and the editor with the TeX source easier; see the
1517 section SOURCE SPECIALS below for more information on this.
1518
1519 The text extracted from the DVI file is in encoded in UTF-8 (you can
1520 view that text by saving the file in UTF-8 format via the File > Save
1521 as ... menu item). If xdvi has been compiled with locale, nl_langin‐
1522 fo() and iconv support, the search term is converted from the character
1523 set specified by the current locale into UTF-8. (See the output of lo‐
1524 cale -a for a list of locale settings available on your system). If
1525 nl_langinfo() is not available, but iconv is, you can specify the input
1526 encoding for iconv via the X resource textEncoding (see the output of
1527 iconv -l for a list of valid encodings). If iconv support is not avail‐
1528 able, only the encodings ISO-8859-1 and UTF-8 are supported (these
1529 names are case-insensitive).
1530
1531 Ideographic characters from CJKV fonts are treated specially: All white
1532 space (spaces and newlines) before and after such characters is ignored
1533 in the search string and in the DVI file.
1534
1535 To match a newline character, use \n in the search string; to match the
1536 string \n, use \\n.
1537
1538 If the checkbox Regular Expression is activated, the string is treated
1539 as a regular expression in extended POSIX syntax, with the following
1540 properties:
1541
1542 - a? matches a zero or one times.
1543
1544 - a* matches a zero or more times.
1545
1546 - a+ matches a one or more times. Note that * and + are greedy, i.e.
1547 they match the longest possible substring.
1548
1549 - The pattern . matches any character except for newline. To also
1550 match a newline, use `(.|\n)'.
1551
1552 - a{n} matches a exactly n times.
1553
1554 - a{n,m} matches a at least n and no more than m times.
1555
1556 - a|b matches a or b. Brackets can be used for grouping, e.g.:
1557 (a|b)|c.
1558
1559 - The string matched by the nth group can be referenced by \n, e.g.
1560 \1 refers to the first match.
1561
1562 - The characters ^ and $ match the beginning and the end of a line,
1563 respectively.
1564
1565 - [abc] matches any of the letters a, b, c, and [a-z] matches all
1566 characters from a to z.
1567
1568 - Each item in a regular expression can also be one of the following
1569 POSIX character classes:
1570 [[:alnum:]] [[:alpha:]] [[:blank:]] [[:cntrl:]] [[:digit:]]
1571 [[:graph:]] [[:lower:]] [[:print:]] [[:space:]] [[:upper:]]
1572
1573
1574 These can be negated by inserting a ^ symbol after the first brack‐
1575 et: [^[:alpha:]]
1576
1577 For more details on POSIX regular expressions, see e.g. the IEEE
1578 Std 1003.1 standard definition available online from:
1579
1580 http://www.opengroup.org/onlinepubs/007904975/basedefs/xbd_chap09.html
1581
1582 - As a non-standard extension, the following Perl-like abbreviations
1583 can be used instead of the POSIX classes:
1584
1585 Symbol Meaning POSIX Class
1586
1587 \w an alphanumeric character [[:alnum:]]
1588 \W a non-alphanumeric character [^[:alnum:]]
1589 \d a digit character [[:digit:]]
1590 \D a non-digit character [^[:digit:]]
1591 \s a whitespace character [[:space:]]
1592 \S a non-whitespace character [^[:space:]]
1593
1594
1595 - The following characters are special symbols; they need to be es‐
1596 caped with \ in order to match them literally: ( ) [ ] . * ? + ^ $
1597 \.
1598
1599 - Matches of length zero are silently skipped.
1600
1601 The dialog also provides checkboxes to:
1602
1603 - search backwards;
1604
1605 - match in a case-sensitive manner (the default is to ignore case,
1606 i.e. a search string Test will match both the strings test and TEST
1607 in the DVI file);
1608
1609 - ignore line breaks and hyphens: This removes all hyphens at the
1610 ends of lines and the following newline characters, and replaces
1611 all remaining newline characters by white spaces. So hyphenated
1612 words will appear as one word to the search, and a search for two
1613 words with a space in between will also match the words if they are
1614 separated by a linebreak.
1615 Note that the hyphen removal may cause unwanted side effects for
1616 compound words containing hyphens that are wrapped after the hy‐
1617 phen, and that replacing the newlines affects the interpretation of
1618 regular expressions as follows: The . pattern will also match new‐
1619 lines, and ^ and $ won't match begin and end of lines any more.
1620 (Since currently there is no option for turning off the greediness
1621 of * and +, turning on this option will usually result in matches
1622 that are longer than desired.)
1623
1624 The current checkbox settings are saved in the ~/.xdvirc file.
1625
1627 The print dialog window allows you to print all pages, marked pages
1628 (click or drag Mouse-2 in the page list to mark them), or a range of
1629 pages. Note that the page numbers always refer to physical pages, so if
1630 you're using the option `use TeX pages', you may want to disable it to
1631 make it easier to determine the correct page numbers (or avoid this
1632 problem altogether by marking the pages to be printed).
1633
1634 The value of the Printer text filed is passed to dvips via the -o!
1635 mechanism, as a single argument after the `!'. Any arguments listed in
1636 the Dvips options field are segmented at whitespaces and passed as sep‐
1637 arate arguments to dvips. If you e.g. want to print the file 2-up, you
1638 should enter the following string into the Printer field:
1639
1640 psnup -2 -q | lpr -Plp
1641
1642
1643 There are several resources for customizing the behaviour and the de‐
1644 fault entries of the print dialog:
1645
1646 dvipsPrinterString
1647
1648 dvipsOptionsString
1649 These can be used to provide default entries for the Printer and
1650 the Dvips options text fields, respectively. If no paper size is
1651 specified in the DVI file (via e.g. \usepackage[dvips]{geometry}
1652 - this is the preferred method), the input field is initialized
1653 with the current value of the command line option/X resource pa‐
1654 per. E.g., the option -paper a4r is translated into the dvips
1655 options -t a4 -t landscape. Note that no check is performed
1656 whether dvips actually understands these options (it will ignore
1657 them if it can't); currently not all options used by xdvi are
1658 also covered by dvips.
1659
1660 dvipsHangTime
1661
1662 dvipsFailHangTime
1663 These specify the time (in milliseconds) that the printing
1664 progress window will stay open after the dvips process has ter‐
1665 minated. The value of dvipsHangTime is used if the process ter‐
1666 minates successfully; dvipsFailHangTime is used if it terminates
1667 with an error. The default values are 1.5 and 5 seconds, respec‐
1668 tively. If both values are negative, the window will stay open
1669 until it is closed by the user.
1670
1672 This dialog allows you to save all or selected/marked pages in the cur‐
1673 rent DVI file. You can save in one of the following formats:
1674
1675 - PostScript (uses dvips to convert the DVI file to a PostScript
1676 file, just like when printing to a PostScript file).
1677
1678 - PDF (first uses dvips to convert the DVI file to a PostScript file,
1679 then uses ps2pdf to convert the PostScript file to PDF).
1680
1681 - Plain text in ISO-8859-1 or UTF-8 encoding. The latter will pre‐
1682 serve more of the special LaTeX characters e.g. from mathematical
1683 mode. Note however that e.g. only few of LaTeX's mathematical sym‐
1684 bols can be rendered correctly as text; so this funcionality works
1685 best for plain text documents. If a character cannot be displayed
1686 in the selected charset, it is replaced by `\' followed by the
1687 hexadecimal character code. If a character is not recognized at
1688 all, it is replaced by `?'.
1689
1690 The programs for PostScript and PDF conversion can be customized via
1691 the command line options or X resources -dvipspath/.dvipsPath and
1692 -ps2pdfpath/.ps2pdfPath, respectively; see the explanation of these op‐
1693 tions above for more details.
1694
1696 The keystroke Ctrl-m [switch-mode()] switches between three different
1697 mouse bindings, which can also be activated via the Modes menu (in Mo‐
1698 tif, this is a submenu of the Options menu called Mouse Mode). The de‐
1699 fault mode at startup can be customized via the X resource mouseMode or
1700 the command-line option -mousemode. The default startup mode is Magni‐
1701 fier Mode.
1702
1703 Note: The modes are implemented by changing the magnifier() action.
1704 Switching the mode will not work if Mouse-1 has been customized to an
1705 action sequence that does not contain the magnifier() action.
1706
1707 Magnifier Mode
1708 In this mode, the mouse buttons 1 to 5 pop up a ``magnifying
1709 glass'' that shows an unshrunken image of the page (i.e. an im‐
1710 age at the resolution determined by the option/X resource pixels
1711 or mfmode) at varying sizes. When the magnifier is moved, small
1712 ruler-like tick marks are displayed at the edges of the magnifi‐
1713 er (unless the X resource delayRulers is set to false, in which
1714 case the tick marks are always displayed). The unit of the
1715 marks is determined by the X resource tickUnits (mm by default).
1716 This unit can be changed at runtime via the action switch-magni‐
1717 fier-units(), by default bound to the keystroke `t' (see the de‐
1718 scription of that key, and of switch-magnifier-units() for more
1719 details on the units available).
1720 The length of the tick marks can be changed via the X resource
1721 tickLength (4 by default). A zero or negative value suppresses
1722 the tick marks.
1723
1724 Text Selection Mode
1725 This mode allows you to select a rectangular region of text in
1726 the DVI file by holding down Mouse-1 and moving the mouse. The
1727 text is put into the X primary selection so that it can be past‐
1728 ed into other X applications with Mouse-2 as usual.
1729 If xdvi has been compiled with locale, nl_langinfo() and iconv
1730 support, the selected text is converted into the character set
1731 of the current locale (see the output of locale -a for a list of
1732 locale settings available on your system). If nl_langinfo() is
1733 not available, but iconv is, you can specify the input encoding
1734 for iconv via the X resource textEncoding (see the output of
1735 iconv -l for a list of valid encodings). If iconv support is not
1736 available, only the encodings ISO-8859-1 and UTF-8 are supported
1737 (these names are case-insensitive).
1738 Note that UTF-8 is the only encoding that can render all charac‐
1739 ters (e.g. mathematical symbols) of a DVI file. If ISO-8859-1 is
1740 active, characters that cannot be displayed are replaced by `\'
1741 followed by the hexadecimal character code. For other encod‐
1742 ings, such characters may trigger iconv error messages. If a
1743 character is not recognized at all, it is replaced by `?'.
1744 To extract larger portions of text, you can alternatively save
1745 selected pages or the entire file in text format via the File >
1746 Save as ... menu.
1747
1748 Ruler Mode
1749 This mode provides a simple way of measuring distances on the
1750 page.
1751 When this mode is activated, the mouse cursor changes into a
1752 thin cross, and a larger, cross-shaped ruler is drawn in the
1753 highlight color at the mouse location. The ruler doesn't have
1754 units attached to it; instead, the current distance between the
1755 ruler and the mouse cursor is continuously printed to the sta‐
1756 tusline.
1757 When activating Ruler Mode, the ruler is at first attached to
1758 the mouse and can be moved around. It can then be positioned at
1759 a fixed place by clicking Mouse-1. After that, the mouse cursor
1760 can be moved to measure the horizontal (dx), vertical (dy) and
1761 direct (shortest) (dr) distance between the ruler center point
1762 and the mouse.
1763 Clicking Mouse-1 again will move the ruler to the current mouse
1764 position, and holding down Mouse-1 will drag the ruler around.
1765 In Ruler Mode, the following special keybindings extend or re‐
1766 place the default bindings:
1767
1768 o [ruler-snap-origin()] Snap the ruler back to the origin
1769 coordinate (0,0).
1770
1771 t [overrides switch-magnifier-units()] Toggle between vari‐
1772 ous ruler units, which can be specified by the X resource
1773 tickUnits (`mm' by default).
1774
1775 P [overrides declare-page-number()] Print the distances
1776 shown in the statusline to standard output.
1777
1779 The Motif toolbar can also be customized. The XPM file used for the
1780 toolbar icons can be specified via the resource toolbarPixmapFile,
1781 which should contain a filename that can be found in one of XFILE‐
1782 SEARCHPATH or XDVIINPUTS (see the section FILE SEARCHING below for more
1783 information on these variables). Xdvi will try to split this pixmap
1784 horizontally into n pieces, where each piece is as wide as the pixmap
1785 is high and is treated as an image for toolbar button n. This means
1786 that each icon should be a square, and that the entire pixmap should
1787 have width n x h if h is the height of the pixmap.
1788
1789 The resource toolbarTranslations can be used to map icons/buttons to
1790 specific actions. The resource should contain a string separated by
1791 newline characters, similar to the resources mainTranslations and menu‐
1792 Translations. Every line must contain either a spacer definition, or
1793 an icon definition:
1794
1795 A spacer definition is a string SPACER(n), where n is the number of
1796 pixels inserted as separator to the following button.
1797
1798 An icon definition is a colon-separated list containing the following
1799 elements:
1800
1801 - the index of an icon in the pixmap file (starting from zero);
1802
1803 - a long tooltip string, displayed in the status area;
1804
1805 - a short tooltip string, displayed as popup;
1806
1807 - a sequence of actions to be performed when the corresponding tool‐
1808 bar button is pushed.
1809
1810 To illustrate this, the default value of toolbarTranslations looks as
1811 follows:
1812
1813 xdvi.toolbarTranslations: \
1814 SPACER(5)\n\
1815 0:Open a new document (Key\\: Ctrl-f):\

1853
1854
1855 When the mouse remains over a toolbar button for a certain period, a
1856 `tooltip' window is shown, describing what the button does using the
1857 short tooltip string from the above resource. At the same time, the
1858 long tooltip string is displayed in the statusline. The appearance and
1859 behaviour of these tooltips can be customized via the following re‐
1860 sources:
1861
1862 tipShell.background
1863 Background color of the tooltip window.
1864
1865 tipShell.fontSet
1866 Font used for the tooltip.
1867
1868 tipShell.waitPeriod
1869 The time (in milliseconds) the mouse pointer needs to be over
1870 the button before the tooltip is shown. Set it to a negative
1871 value to suppress the tooltips altogether.
1872
1873
1875 The greyscale anti-aliasing feature in xdvi will not work at its best
1876 if the display does not have enough colors available. This can happen
1877 if other applications are using most of the colormap (even if they are
1878 iconified). If this occurs, then xdvi will print an error message and
1879 turn on the -copy option. This will result in overstrike characters
1880 appearing wrong; it may also result in poor display quality if the num‐
1881 ber of available colors is very small.
1882
1883 Typically this problem occurs on displays that allocate eight bits of
1884 video memory per pixel. To see how many bits per pixel your display
1885 uses, type xwininfo in an xterm window, and then click the mouse on the
1886 root window when asked. The ``Depth:'' entry will tell you how many
1887 bits are allocated per pixel.
1888
1889 Displays using at least 15 bits per pixel are typically TrueColor visu‐
1890 als, which do not have this problem, since their colormap is permanent‐
1891 ly allocated and available to all applications. (The visual class is
1892 also displayed by xwininfo.) For more information on visual classes
1893 see the documentation for the X Window System.
1894
1895 To alleviate this problem, therefore, one may (a) run with more bits
1896 per pixel (this may require adding more video memory or replacing the
1897 video card), (b) shut down other applications that may be using much of
1898 the colormap and then restart xdvi, or (c) run xdvi with the -install
1899 option.
1900
1901 One application which is often the cause of this problem is Netscape.
1902 In this case there are two more alternatives to remedying the situa‐
1903 tion. One can run ``netscape -install'' to cause Netscape to install a
1904 private colormap. This can cause colors to change in bizarre ways when
1905 the mouse is moved to a different window. Or, one can run ``netscape
1906 -ncols 220'' to limit Netscape to a smaller number of colors. A small‐
1907 er number will ensure that other applications have more colors avail‐
1908 able, but will degrade the color quality in the Netscape window.
1909
1910
1912 Xdvi can display Encapsulated PostScript (EPS) files included in the
1913 dvi file. Such files are first searched for in the directory where the
1914 dvi file is, and then using normal Kpathsea rules. There is an excep‐
1915 tion to this, however: if the file name begins with a backtick (`),
1916 then the remaining characters in the file name give a shell command
1917 (often zcat) which is executed; its standard output is then sent to be
1918 interpreted as PostScript. Since the execution of arbitrary shell com‐
1919 mands with the user's permissions is a huge security risk, evaluation
1920 of these backtick commands is disabled by default. It needs to be acti‐
1921 vated via the -allowshell command-line option. NOTE: You should never
1922 use this option when viewing documents that you didn't compile your‐
1923 self. The backtick specials are not needed for uncompressing gzipped
1924 PostScript files, since xdvi can do that on the fly if the filename
1925 ends with .eps.gz or .eps.Z (and if the first bytes of the file indi‐
1926 cate that the file is indeed compressed). This is both safer and more
1927 flexible than the backtick approach, since the default file searching
1928 rules will apply to such filenames too.
1929
1931 Using FreeType (version 2), xdvi can render PostScript<tm> Type 1 fonts
1932 directly, without the route via TeX pixel (pk) fonts. The advantage of
1933 this is that only one size of each font needs to be stored on disk.
1934 Unless the -notype1fonts option is used, xdvi will try to render every
1935 font using FreeType. Only as a fallback will it invoke an external pro‐
1936 gram (like mktexpk, which in turn may invoke utilities like ps2pk or
1937 gsftopk) to generate a pixel font from the Type 1 source. The direct
1938 rendering of the Computer Modern fonts should work out-of-the box,
1939 whereas other Type 1 fonts such as the 35 `standard' PostScript<tm>
1940 fonts resident in printers may need to be made accessible for use with
1941 xdvi, unless your system administrator or TeX distribution has already
1942 done so (which is the case e.g. for current TeX Live systems). For the
1943 35 PostScript<tm> resident fonts, xdvik will search using the Fontmap
1944 provided with Ghostscript, if necessary. Also, the xdvik distribution
1945 comes with a utility called t1mapper to make these fonts available for
1946 xdvi; see the manual page for t1mapper(1) for usage details. This pro‐
1947 gram is likely to be dropped in the future, however, since it is proba‐
1948 bly not needed anymore.
1949
1951 Any of the specials used by xdvi may be preceded by the characters
1952 ``xdvi:''. Doing so does not change the behavior of the special under
1953 xdvi, but it tells other dvi drivers (such as e.g. dvips) to ignore the
1954 special.
1955
1957 Some TeX implementations or macro packages provide the facility to au‐
1958 tomatically include so-called `source specials' into a DVI file. These
1959 contain the line number, eventually a column number, and the filename
1960 of the .tex source. This makes it possible to jump from a .dvi file to
1961 the corresponding place in the .tex source and vice versa (also called
1962 `inverse search' - jumping from the DVI file to the TeX file is also
1963 known as `reverse search', and jumping from the TeX file to the DVI
1964 file as `forward search').
1965
1966 To be usable with xdvi, source specials in the dvi file must have one
1967 of the following formats:
1968
1969 src:line[ ]filename
1970 src:line:col[ ]filename
1971 src:line
1972 src:line:col
1973 src::col
1974
1975 If filename or line are omitted, the most recent values are used. The
1976 first source special on each page must be in one of the first two
1977 forms, since defaults are not inherited across pages.
1978
1979 You will need a TeX implementation that provides an appropriate switch
1980 (e.g. -src) or a macro package (such as srcltx.sty or srctex.sty,
1981 available from CTAN:macros/latex/contrib/supported/srcltx/) to insert
1982 such source specials into the DVI file.
1983
1984 For reverse search, the combination Ctrl-Mouse 1 will make xdvi open an
1985 editor (the value of the -editor command line option) with the file and
1986 the line number of the .tex source. See the description of the -editor
1987 option for more information and example settings.
1988
1989 For forward search, xdvi has a -sourceposition option that makes xdvi
1990 jump to the page in the DVI file corresponding to the given line (or
1991 the closest line having a source special) of the specified file and
1992 highlight the found region. See the description of the -sourceposition
1993 option for more details.
1994
1995 More information on setting up various editors for use with source spe‐
1996 cials can be found at:

1999
2000
2002 xdvi accepts specials to set the paper size for the document. These
2003 specials should be of the form
2004
2005 papersize=[*]width,height
2006
2007
2008 where width and height give the width and height of the paper, respec‐
2009 tively. Each of these should appear in the form of a decimal number
2010 followed by any of the two-letter abbreviations for units accepted by
2011 TeX (pt, pc, in, bp, cm, mm, dd, cc, or sp). If an asterisk (*) ap‐
2012 pears just before the width, then the measurements refer to the docu‐
2013 ment dimensions (e.g., pt as opposed to truept). This allows a macro
2014 package to vary the page size according to elements of the document;
2015 e.g.,
2016
2017 \special{xdvi: papersize=*\number\wd\mybox sp,
2018 \number\ht\mybox sp}
2019
2020
2021 Except for the asterisk, this format is compatible with dvips.
2022
2023 The last papersize special on a page determines the size of that page.
2024 If there is no such special on a given page, the most recent papersize
2025 is used, or, if there are no papersize specials on any preceding page,
2026 then the value of the paper resource (or -paper option on the command
2027 line) is used. Thus the paper size may vary for different pages of the
2028 dvi file.
2029
2030 If the paper resource (or -paper command-line option) begins with a
2031 plus sign (`+'), then all papersize specials in the dvi file are ig‐
2032 nored.
2033
2035 The color specials supported by xdvi are the same as those supported by
2036 dvips, except that the literal PostScript color specification (as in
2037 the AggiePattern example in the dvips documentation) is not supported.
2038 There are also some restrictions due to the way xdvi's drawing rou‐
2039 tines are implemented; e.g. the \colorbox and \fcolorbox macros don't
2040 work with xdvi. See the section LIMITATIONS below for more information
2041 on these restrictions. Xdvi supports the same list of named colors as
2042 dvips does, namely:
2043
2044 Apricot, Aquamarine, Bittersweet, Black, Blue, BlueGreen, BlueViolet,
2045 BrickRed, Brown, BurntOrange, CadetBlue, CarnationPink, Cerulean, Corn‐
2046 flowerBlue, Cyan, Dandelion, DarkOrchid, Emerald, ForestGreen, Fuchsia,
2047 Goldenrod, Gray, Green, GreenYellow, JungleGreen, Lavender, LimeGreen,
2048 Magenta, Mahogany, Maroon, Melon, MidnightBlue, Mulberry, NavyBlue,
2049 OliveGreen, Orange, OrangeRed, Orchid, Peach, Periwinkle, PineGreen,
2050 Plum, ProcessBlue, Purple, RawSienna, Red, RedOrange, RedViolet, Rho‐
2051 damine, RoyalBlue, RoyalPurple, RubineRed, Salmon, SeaGreen, Sepia,
2052 SkyBlue, SpringGreen, Tan, TealBlue, Thistle, Turquoise, Violet, Viole‐
2053 tRed, White, WildStrawberry, Yellow, YellowGreen, YellowOrange.
2054
2055 Note that these names are case sensitive.
2056
2057 The documentation of the LaTeX color package provides more details on
2058 how to use such specials with LaTeX; see the dvips documentation for a
2059 detailed description of the syntax and semantics of the color specials.
2060
2062 When xdvi receives a SIGUSR1 signal, it rereads the dvi file.
2063
2065 Xdvik uses the same environment variables and algorithms for searching
2066 for font files as TeX and friends. See the documentation for the
2067 Kpathsea library, kpathsea.dvi, for a detailed description of these.
2068
2069 In addition, xdvik accepts the following variables:
2070
2071 DISPLAY
2072 Specifies which graphics display terminal to use.
2073
2074 KPATHSEA_DEBUG
2075 Trace Kpathsea lookups; set it to -1 (= all bits on) for com‐
2076 plete tracing.
2077
2078 EXTENSIONMAPS
2079 A list of files to be searched for mime types entries (as for
2080 Acrobat Reader). Earlier entries in one of these files override
2081 later ones. If this variable is not set, the following default
2082 path is used:
2083
2084 $HOME/.mime.types:/etc/mime.types:\
2085 /usr/etc/mime.types:/usr/local/etc/mime.types
2086
2087
2088
2089 MAILCAPS
2090 A list of files to be searched for mailcap entries, as defined
2091 by RFC 1343. See this RFC or the mailcap(4) manual page for a
2092 detailed description of the mailcap file format. Currently, on‐
2093 ly the following mailcap features are supported:
2094
2095 test=command
2096 The entry is only used if command can be executed via the
2097 system() call and if the system() call returns with value
2098 0 (success). The command string may contain the format
2099 string %s, which will be replaced by the file name.
2100
2101 needsterminal
2102 If this flag is used, the command will be executed in a
2103 new xterm window by prepending ``xterm -e '' to the com‐
2104 mand string.
2105
2106 All other fields in the mailcap entry are ignored by xdvi. Ear‐
2107 lier entries in one of these files override later ones. If the
2108 variable is not defined, the following default path is used:
2109
2110 $HOME/.mailcap:/etc/mailcap:/usr/etc/mailcap:\
2111 /usr/local/etc/mailcap
2112
2113 For security reasons, some special characters (i.e.: ( ) ` \ ;)
2114 are escaped in the argument before passing it to system().
2115
2116 BROWSER
2117 Determines the web browser used to open external links (i.e.,
2118 all URLs that don't start with the `file:' scheme and are not
2119 relative links in the local DVI file), and to open links for
2120 which no viewer has been specified in the mailcap files. The
2121 value of this variable is a colon-separated list of commands.
2122 Xdvi will try each of them in sequence until one succeeds (i.e.
2123 doesn't immediately return with status 0). This allows you to
2124 specify your favourite browser at the beginning, and fallback
2125 browsers at the end. Every occurrence of %s in the string is re‐
2126 placed by the target URL; every occurrence of %% is replaced by
2127 a single %. If no %s is present, the URL string is added as an
2128 extra argument.
2129 An example setting is:
2130
2131 netscape -raise -remote 'openURL(%s,new-window)':xterm -e lynx
2132 %s:xterm -e wget %s:lynx %s:wget %s
2133
2134 See
2135
2136 http://www.catb.org/~esr/BROWSER/
2137
2138 for more details on the BROWSER environment variable.
2139
2140 GS_LIB A colon-separated list of directories to search for Fontmap
2141 files, etc., as used for Ghostscript. It has the same meaning
2142 as it does when running Ghostscript. In xdvik, it is used when
2143 searching for font files when the map file does not give a file
2144 name for the font (this should be quite rare). The command gs
2145 -h will list the default value that Ghostscript uses. See also
2146 the XDVI_GS_LIB environment variable (below).
2147
2148 XDVI_GS_LIB
2149 This has the same effect as GS_LIB but affects only xdvi. Use
2150 this when you want to use a different value for GS_LIB when run‐
2151 ning xdvi, but use either the compiled-in default value or some
2152 other value when running Ghostscript. If both GS_LIB and XD‐
2153 VI_GS_LIB are set, then xdvi uses XDVI_GS_LIB. To use the de‐
2154 fault value compiled in to xdvi while still retaining the abili‐
2155 ty to set GS_LIB for use with Ghostscript, you can set XD‐
2156 VI_GS_LIB to the empty string.
2157
2158 TMPDIR The directory to use for storing temporary files created when
2159 uncompressing PostScript files.
2160
2161 XEDITOR
2162 Determines the editor command used for source special `reverse
2163 search', if neither the -editor command-line option nor the .ed‐
2164 itor resource are specified. See the description of the -ed‐
2165 itor command line option for details on the format.
2166
2167 VISUAL Determines an editor to be opened in an xterm window if neither
2168 of -editor, .editor, or XEDITOR is specified.
2169
2170 EDITOR Determines an editor to be opened in an xterm window if neither
2171 of -editor, .editor, XEDITOR or VISUAL is specified.
2172
2173 WWWBROWSER
2174 Obsolete; use BROWSER instead.
2175
2177 xdvi accepts many but not all types of PostScript specials accepted by
2178 dvips. For example, it accepts most specials generated by epsf and ps‐
2179 fig. It does not, however, support bop-hook or eop-hook, nor does it
2180 allow PostScript commands to affect the rendering of things that are
2181 not PostScript (for example, the ``NEAT'' and rotated ``A'' examples in
2182 the dvips manual). These restrictions are due to the design of xdvi;
2183 in all likelihood they will always remain.
2184
2185 LaTeX2e rotation specials are currently not supported.
2186
2187 MetaPost files containing included text are not supported.
2188
2189 Xdvi's color handling doesn't support the \colorbox and \fcolorbox
2190 macros; this is not likely to change in the near future. This also
2191 means that e.g. colored tables (as created by the colortbl package)
2192 may render incorrectly: Text in colors different from the default fore‐
2193 ground color may not be displayed. When the page is redrawn (e.g. after
2194 using the magnifier), the background color of the cells may overdraw
2195 the text.
2196
2198 $HOME/.xdvirc
2199 A file that holds all settings that the user changed via the
2200 keys, the `Options' and the Xaw `Modes' menu and the dialogs, as
2201 X resources. These resources override the settings in
2202 $HOME/.Xdefaults. This file is ignored if the -q option is used
2203 or the noInitFile X resource is set.
2204
2205 config.xdvi
2206 An optional configuration file for the Type 1 font setup, which
2207 specifies dvips-style map files specific to xdvik. If used, it
2208 should be present in the directory determined by the TEXCONFIG
2209 environment variable. Its format is similar to configuration
2210 files for dvips, except that it is only scanned for the names of
2211 map files (p and p+ directives).
2212
2214 X(1), dvips(1), mktexpk(1), ps2pk(1), gsftopk(1), t1mapper(1), mail‐
2215 cap(4), the Kpathsea documentation, and the Xdvik home page at
2216 http://xdvi.sourceforge.net/.

2219 Eric Cooper, CMU, did a version for direct output to a QVSS. Modified
2220 for X by Bob Scheifler, MIT Laboratory for Computer Science. Modified
2221 for X11 by Mark Eichin, MIT SIPB. Additional enhancements by many oth‐
2222 ers.
