10 groff -m ms [option ...] [input-file ...]
11
13 This manual page describes the GNU version of the ms macros, part of
14 the groff typesetting system. The ms macros are mostly compatible with
15 the documented behavior of the 4.3 BSD Unix ms macros (see Differences
16 from troff ms below for details). The ms macros are suitable for
17 reports, letters, books, and technical documentation.
18
20 The ms macro package expects files to have a certain amount of
21 structure. The simplest documents can begin with a paragraph macro and
22 consist of text separated by paragraph macros or even blank lines.
23 Longer documents have a structure as follows:
24
25 Document type
26 If you use the RP (report) macro at the beginning of the
27 document, groff prints the cover page information on its own
28 page; otherwise it prints the information on the first page with
29 your document text immediately following. Other document
30 formats found in AT&T troff are specific to AT&T or Berkeley,
31 and are not supported in groff ms.
32
33 Format and layout
34 By setting number registers, you can change your document's
35 margins, spacing, headers and footers, footnotes, and the base
36 point size for the text. See Document control registers below
37 for more details.
38
39 Cover page
40 A cover page consists of a title, and optionally the author's
41 name and institution, an abstract, and the date. See Cover page
42 macros below for more details.
43
44 Body Following the cover page is your document. It consists of
45 paragraphs, headings, and lists.
46
47 Table of contents
48 Longer documents usually include a table of contents, which you
49 can add by placing the TC macro at the end of your document.
50
51 Document control registers
52 The following table lists the document control number registers. For
53 the sake of consistency, set registers related to margins at the
54 beginning of your document, or just after the RP macro.

113 Cover page macros
114 Use the following macros to create a cover page for your document in
115 the order shown.
116
117 .RP [no]
118 Specifies the report format for your document. The report
119 format creates a separate cover page. With no RP macro, groff
120 prints a subset of the cover page on page 1 of your document.
121
122 If you use the optional no argument, groff prints a title page
123 but does not repeat any of the title page information (title,
124 author, abstract, etc.) on page 1 of the document.
125
126 .P1 (P-one) Prints the header on page 1. The default is to suppress
127 the header.
128
129 .DA [xxx]
130 (optional) Print the current date, or the arguments to the macro
131 if any, on the title page (if specified) and in the footers.
132 This is the default for nroff.
133
134 .ND [xxx]
135 (optional) Print the current date, or the arguments to the macro
136 if any, on the title page (if specified) but not in the footers.
137 This is the default for troff.
138
139 .TL Specifies the document title. Groff collects text following the
140 TL macro into the title, until reaching the author name or
141 abstract.
142
143 .AU Specifies the author's name. You can specify multiple authors
144 by using an AU macro for each author.
145
146 .AI Specifies the author's institution. You can specify multiple
147 institutions.
148
149 .AB [no]
150 Begins the abstract. The default is to print the word ABSTRACT,
151 centered and in italics, above the text of the abstract. The
152 option no suppresses this heading.
153
154 .AE End the abstract.
155
156 Paragraphs
157 Use the PP macro to create indented paragraphs, and the LP macro to
158 create paragraphs with no initial indent.
159
160 The QP macro indents all text at both left and right margins by the
161 amount of the register QI. The effect is reminiscent of the HTML
162 <BLOCKQUOTE> tag. The next paragraph or heading returns the margins to
163 normal. QP inserts the vertical space specified in register PD as
164 inter-paragraph spacing.
165
166 A paragraph bracketed between the macros QS and QE has the same
167 appearance as a paragraph started with QP and a following paragraph
168 started with LP. Both QS and QE insert the inter-paragraph spacing
169 specified in PD and the text is indented on both sides by the amount of
170 register QI. The text between QS and QE can be split into further
171 paragraphs by using .LP or .PP.
172
173 The XP macro produces an “exdented” paragraph; that is, one with a
174 hanging indent. The first line of the paragraph begins at the left
175 margin, and subsequent lines are indented (the opposite of PP).
176
177 For each of the above paragraph types, and also for any list entry
178 introduced by the IP macro (described later), the document control
179 register PORPHANS, sets the minimum number of lines which must be
180 printed, after the start of the paragraph, and before any page break
181 occurs. If there is insufficient space remaining on the current page
182 to accommodate this number of lines, then a page break is forced before
183 the first line of the paragraph is printed.
184
185 Similarly, when a section heading (see subsection “Headings” below)
186 precedes any of these paragraph types, the HORPHANS document control
187 register specifies the minimum number of lines of the paragraph which
188 must be kept on the same page as the heading. If insufficient space
189 remains on the current page to accommodate the heading and this number
190 of lines of paragraph text, then a page break is forced before the
191 heading is printed.
192
193 Headings
194 Use headings to create a hierarchical structure for your document. By
195 default, the ms macros print headings in bold using the same font
196 family and point size as the body text. For output devices which
197 support scalable fonts, this behaviour may be modified by defining the
198 document control registers GROWPS and PSINCR.
199
200 The following heading macros are available:
201
202 .NH xx Numbered heading. The argument xx is either a numeric argument
203 to indicate the level of the heading, or S xx xx ... to set the
204 section number explicitly. If you specify heading levels out of
205 sequence, such as invoking .NH 3 after .NH 1, groff prints a
206 warning on standard error.
207
208 If the GROWPS register is set to a value greater than the level
209 of the heading, then the point size of the heading will be
210 increased by PSINCR units over the text size specified by the PS
211 register, for each level by which the heading level is less than
212 the value of GROWPS. For example, the sequence:
213
214 .nr PS 10
215 .nr GROWPS 3
216 .nr PSINCR 1.5p
217 .
218 .NH 1
219 Top Level Heading
220 .
221 .NH 2
222 Second Level Heading
223 .
224 .NH 3
225 Third Level Heading
226
227 will cause “1. Top Level Heading” to be printed in 13pt bold
228 text, followed by “1.1. Second Level Heading” in 11.5pt bold
229 text, while “1.1.1. Third Level Heading”, and all more deeply
230 nested heading levels, will remain in the 10pt bold text which
231 is specified by the PS register.
232
233 Note that the value stored in PSINCR is interpreted in groff
234 basic units; the p scaling factor should be employed when
235 assigning a value specified in points.
236
237 The style used to represent the section number, within a
238 numbered heading, is controlled by the SN-STYLE string; this may
239 be set to either the SN-DOT or the SN-NO-DOT style, (described
240 below), by aliasing SN-STYLE accordingly. By default, SN-STYLE
241 is initialised by defining the alias
242
243 .als SN-STYLE SN-DOT
244
245 it may be changed to the SN-NO-DOT style, if preferred, by
246 defining the alternative alias
247
248 .als SN-STYLE SN-NO-DOT
249
250 Any such change becomes effective with the first use of .NH,
251 after the new alias is defined.
252
253 After invoking .NH, the assigned heading number is available in
254 the strings SN-DOT (as it appears in the default formatting
255 style for numbered headings, with a terminating period following
256 the number), and SN-NO-DOT (with this terminating period
257 omitted). The string SN is also defined, as an alias for
258 SN-DOT; if preferred, the user may redefine it as an alias for
259 SN-NO-DOT, by including the initialisation:
260
261 .als SN SN-NO-DOT
262
263 at any time; the change becomes effective with the next use of
264 .NH, after the new alias is defined.
265
266 .SH [xx]
267 Unnumbered subheading. The use of the optional xx argument is a
268 GNU extension, which adjusts the point size of the unnumbered
269 subheading to match that of a numbered heading, introduced using
270 .NH xx with the same value of xx. For example, given the same
271 settings for PS, GROWPS and PSINCR, as used in the preceding .NH
272 example, the sequence:
273
274 .SH 2
275 An Unnumbered Subheading
276
277 will print “An Unnumbered Subheading” in 11.5pt bold text.
278
279 Highlighting
280 The ms macros provide a variety of methods to highlight or emphasize
281 text:
282
283 .B [txt [post [pre]]]
284 Sets its first argument in bold type. If you specify a second
285 argument, groff prints it in the previous font after the bold
286 text, with no intervening space (this allows you to set
287 punctuation after the highlighted text without highlighting the
288 punctuation). Similarly, it prints the third argument (if any)
289 in the previous font before the first argument. For example,
290
291 .B foo ) (
292
293 prints “(foo)”.
294
295 If you give this macro no arguments, groff prints all text
296 following in bold until the next highlighting, paragraph, or
297 heading macro.
298
299 .R [txt [post [pre]]]
300 Sets its first argument in roman (or regular) type. It operates
301 similarly to the B macro otherwise.
302
303 .I [txt [post [pre]]]
304 Sets its first argument in italic type. It operates similarly
305 to the B macro otherwise.
306
307 .CW [txt [post [pre]]]
308 Sets its first argument in a constant-width face. It operates
309 similarly to the B macro otherwise.
310
311 .BI [txt [post [pre]]]
312 Sets its first argument in bold italic type. It operates
313 similarly to the B macro otherwise.
314
315 .BX [txt]
316 Prints its argument and draws a box around it. If you want to
317 box a string that contains spaces, use a digit-width space (\0).
318
319 .UL [txt [post]]
320 Prints its first argument with an underline. If you specify a
321 second argument, groff prints it in the previous font after the
322 underlined text, with no intervening space.
323
324 .LG Prints all text following in larger type (2 points larger than
325 the current point size) until the next font size, highlighting,
326 paragraph, or heading macro. You can specify this macro
327 multiple times to enlarge the point size as needed.
328
329 .SM Prints all text following in smaller type (2 points smaller than
330 the current point size) until the next type size, highlighting,
331 paragraph, or heading macro. You can specify this macro
332 multiple times to reduce the point size as needed.
333
334 .NL Prints all text following in the normal point size (that is, the
335 value of the PS register).
336
337 \*{text\*}
338 Print the enclosed text as a superscript.
339
340 Indents
341 You may need to indent sections of text. A typical use for indents is
342 to create nested lists and sublists.
343
344 Use the RS and RE macros to start and end a section of indented text,
345 respectively. The PI register controls the amount of indent.
346
347 You can nest indented sections as deeply as needed by using multiple,
348 nested pairs of RS and RE.
349
350 Lists
351 The IP macro handles duties for all lists. Its syntax is as follows:
352
353 .IP [marker [width]]
354 The marker is usually a bullet character \(bu for unordered
355 lists, a number (or auto-incrementing number register) for
356 numbered lists, or a word or phrase for indented (glossary-
357 style) lists.
358
359 The width specifies the indent for the body of each list item.
360 Once specified, the indent remains the same for all list items
361 in the document until specified again.
362
363 Tab stops
364 Use the ta request to set tab stops as needed. Use the TA macro to
365 reset tabs to the default (every 5n). You can redefine the TA macro to
366 create a different set of default tab stops.
367
368 Displays and keeps
369 Use displays to show text-based examples or figures (such as code
370 listings). Displays turn off filling, so lines of code can be
371 displayed as-is without inserting br requests in between each line.
372 Displays can be kept on a single page, or allowed to break across
373 pages. The following table shows the display types available.
374
375 Display macro Type of display
376 With keep No keep
377 ─────────────────────────────────────────────────────────────────
378 .DS L .LD Left-justified.
379 .DS I [indent] .ID Indented (default indent in the DI
380 register).
381 .DS B .BD Block-centered (left-justified,
382 longest line centered).
383 .DS C .CD Centered.
384 .DS R .RD Right-justified.
385 ─────────────────────────────────────────────────────────────────
386
387 Use the DE macro to end any display type. The macros Ds and De were
388 formerly provided as aliases for DS and DE, respectively, but they have
389 been removed, and should no longer be used. X11 documents which
390 actually use Ds and De always load a specific macro file from the X11
391 distribution (macros.t) which provides proper definitions for the two
392 macros.
393
394 To keep text together on a page, such as a paragraph that refers to a
395 table (or list, or other item) immediately following, use the KS and KE
396 macros. The KS macro begins a block of text to be kept on a single
397 page, and the KE macro ends the block.
398
399 You can specify a floating keep using the KF and KE macros. If the
400 keep cannot fit on the current page, groff holds the contents of the
401 keep and allows text following the keep (in the source file) to fill in
402 the remainder of the current page. When the page breaks, whether by an
403 explicit bp request or by reaching the end of the page, groff prints
404 the floating keep at the top of the new page. This is useful for
405 printing large graphics or tables that do not need to appear exactly
406 where specified.
407
408 The macros B1 and B2 can be used to enclose a text within a box; .B1
409 begins the box, and .B2 ends it. Text in the box is automatically
410 placed in a diversion (keep).
411
412 Tables, figures, equations, and references
413 The ms macros support the standard groff preprocessors: tbl, pic, eqn,
414 and refer. Mark text meant for preprocessors by enclosing it in pairs
415 of tags as follows:
416
417 .TS [H] and .TE
418 Denote a table to be processed by the tbl preprocessor. The
419 optional H argument instructs groff to create a running header
420 with the information up to the TH macro. Groff prints the
421 header at the beginning of the table; if the table runs onto
422 another page, groff prints the header on the next page as well.
423
424 .PS and .PE
425 Denote a graphic to be processed by the pic preprocessor. You
426 can create a pic file by hand, using the AT&T pic manual
427 available on the Web as a reference, or by using a graphics
428 program such as xfig.
429
430 .EQ [align] and .EN
431 Denote an equation to be processed by the eqn preprocessor. The
432 optional align argument can be C, L, or I to center (the
433 default), left-justify, or indent the equation, respectively.
434
435 .[ and .]
436 Denote a reference to be processed by the refer preprocessor.
437 The GNU refer(1) manual page provides a comprehensive reference
438 to the preprocessor and the format of the bibliographic
439 database.
440
441 Footnotes
442 The ms macros provide a flexible footnote system. You can specify a
443 numbered footnote by using the \** escape, followed by the text of the
444 footnote enclosed by FS and FE macros.
445
446 You can specify symbolic footnotes by placing the mark character (such
447 as \(dg for the dagger character) in the body text, followed by the
448 text of the footnote enclosed by FS \(dg and FE macros.
449
450 You can control how groff prints footnote numbers by changing the value
451 of the FF register as follows:
452
453 0 Prints the footnote number as a superscript; indents the
454 footnote (default).
455
456 1 Prints the number followed by a period (that is, “1.”)
457 and indents the footnote.
458
459 2 Like 1, without an indent.
460
461 3 Like 1, but prints the footnote number as a paragraph
462 with a hanging indent.
463
464 You can use footnotes safely within keeps and displays, but avoid using
465 numbered footnotes within floating keeps. You can set a second \**
466 between a \** and its corresponding .FS; as long as each .FS occurs
467 after the corresponding \** and the occurrences of .FS are in the same
468 order as the corresponding occurrences of \**.
469
470 Headers and footers
471 There are three ways to define headers and footers:
472
473 • Use the strings LH, CH, and RH to set the left, center, and right
474 headers. Use LF, CF, and RF to set the left, center, and right
475 footers. The string-setting approach works best for documents that
476 do not distinguish between odd and even pages.
477
478 • Use the OH and EH macros to define headers for the odd and even
479 pages, and OF and EF macros to define footers for the odd and even
480 pages. This is more flexible than defining the individual strings.
481 The syntax for these macros is as follows:
482
483 .XX 'left'center'right'
484
485 where XX is one of the foregoing four macros and each of left,
486 center, and right is text of your choice. You can replace the quote
487 (') marks with any character not appearing in the header or footer
488 text.
489
490 • You can redefine the PT and BT macros to change the behavior of the
491 header and footer, respectively. The header process also calls the
492 (undefined) HD macro after PT; you can define this macro if you need
493 additional processing after printing the header (for example, to
494 draw a line below the header).
495
496 Margins
497 You control margins using a set of number registers. The following
498 table lists the register names and defaults:
499
500 Reg. Definition Effective Default
501 ────────────────────────────────────────────────────────────
502 PO Page offset (left margin) next page 1i
503 LL Line length next paragraph 6i
504 LT Header/footer length next paragraph 6i
505 HM Top (header) margin next page 1i
506 FM Bottom (footer) margin next page 1i
507 ────────────────────────────────────────────────────────────
508
509 Note that there is no right margin setting. The combination of page
510 offset and line length provide the information necessary to derive the
511 right margin.
512
513 Multiple columns
514 The ms macros can set text in as many columns as will reasonably fit on
515 the page. The following macros are available. All of them force a
516 page break if a multi-column mode is already set. However, if the
517 current mode is single-column, starting a multi-column mode does not
518 force a page break.
519
520 .1C Single-column mode.
521
522 .2C Two-column mode.
523
524 .MC [column-width [gutter-width]]
525 Multi-column mode. If you specify no arguments, it is
526 equivalent to the 2C macro. Otherwise, column-width is the
527 width of each column and gutter-width is the space between
528 columns. The MINGW number register is the default gutter width.
529
530 Creating a table of contents
531 Wrap text that you want to appear in the table of contents in XS and XE
532 macros. Use the TC macro to print the table of contents at the end of
533 the document, resetting the page number to i (Roman numeral 1).
534
535 You can manually create a table of contents by specifying a page number
536 as the first argument to XS. Add subsequent entries using the XA
537 macro. For example:
538
539 .XS 1
540 Introduction
541 .XA 2
542 A Brief History of the Universe
543 .XA 729
544 Details of Galactic Formation
545 ...
546 .XE
547
548 Use the PX macro to print a manually-generated table of contents
549 without resetting the page number.
550
551 If you give the argument no to either PX or TC, groff suppresses
552 printing the title specified by the \*[TOC] string.
553
554 Fractional point sizes
555 Traditionally, the ms macros only support integer values for the
556 document's font size and vertical spacing. To overcome this
557 restriction, values larger than or equal to 1000 are taken as
558 fractional values, multiplied by 1000. For example, ‘.nr PS 10250’
559 sets the font size to 10.25 points.
560
561 The following four registers accept fractional point sizes: PS, VS,
562 FPS, and FVS.
563
564 Due to backwards compatibility, the value of VS must be smaller than
565 40000 (this is 40.0 points).
566
568 The groff ms macros are a complete re-implementation, using no original
569 AT&T code. Since they take advantage of the extended features in
570 groff, they cannot be used with AT&T troff. Other differences include:
571
572 • The internals of groff ms differ from the internals of Unix ms.
573 Documents that depend upon implementation details of Unix ms may not
574 format properly with groff ms.
575
576 • The error-handling policy of groff ms is to detect and report
577 errors, rather than silently to ignore them.
578
579 • Some Bell Labs localisms are not implemented by default. However,
580 if you call the otherwise undocumented SC section-header macro, you
581 will enable implementations of three other archaic Bell Labs macros:
582 UC, P1, and P2. These are not enabled by default because (a) they
583 were not documented, in the original ms manual, and (b) the P1 and
584 UC macros both collide with different macros in the Berkeley version
585 of ms.
586
587 These emulations are sufficient to give back the 1976 Kernighan &
588 Cherry paper Typesetting Mathematics – User's Guide its section
589 headings, and restore some text that had gone missing as arguments
590 of undefined macros. No warranty express or implied is given as to
591 how well the typographic details these produce match the original
592 Bell Labs macros.
593
594 • Berkeley localisms, in particular the TM and CT macros, are not
595 implemented.
596
597 • Groff ms does not work in compatibility mode (e.g., with the -C
598 option).
599
600 • There is no support for typewriter-like devices.
601
602 • Groff ms does not provide cut marks.
603
604 • Multiple line spacing is not supported (use a larger vertical
605 spacing instead).
606
607 • Some Unix ms documentation says that the CW and GW number registers
608 can be used to control the column width and gutter width,
609 respectively. These number registers are not used in groff ms.
610
611 • Macros that cause a reset (paragraphs, headings, etc.) may change
612 the indent. Macros that change the indent do not increment or
613 decrement the indent, but rather set it absolutely. This can cause
614 problems for documents that define additional macros of their own.
615 The solution is to use not the in request but instead the RS and RE
616 macros.
617
618 • The number register GS is set to 1 by the groff ms macros, but is
619 not used by the Unix ms macros. Documents that need to determine
620 whether they are being formatted with Unix ms or groff ms should use
621 this number register.
622
623 • To make groff ms use the default page offset (which also specifies
624 the left margin), the PO number register must stay undefined until
625 the first ms macro is evaluated. This implies that PO should not be
626 used early in the document, unless it is changed also: remember that
627 accessing an undefined register automatically defines it.
628
629 Strings
630 You can redefine the following strings to adapt the groff ms macros to
631 languages other than English:

652 The \*- string produces an em dash—like this.
653
654 Use \*Q and \*U to get a left and right typographer's quote,
655 respectively, in troff (and plain quotes in nroff).
656
657 Text Settings
658 The FAM string sets the default font family. If this string is
659 undefined at initialization, it is set to Times.
660
661 The point size, vertical spacing, and inter-paragraph spacing for
662 footnotes are controlled by the number registers FPS, FVS, and FPD; at
663 initialization these are set to \n(PS-2, \n[FPS]+2, and \n(PD/2,
664 respectively. If any of these registers are defined before
665 initialization, the initialization macro does not change them.
666
667 The hyphenation flags (as set by the hy request) are set from the HY
668 register; the default is 6.
669
670 Improved accent marks (as originally defined in Berkeley's ms version)
671 are available by specifying the AM macro at the beginning of your
672 document. You can place an accent over most characters by specifying
673 the string defining the accent directly after the character. For
674 example, n\*~ produces an n with a tilde over it.
675
677 The following conventions are used for names of macros, strings, and
678 number registers. External names available to documents that use the
679 groff ms macros contain only uppercase letters and digits.
680
681 Internally the macros are divided into modules; naming conventions are
682 as follows:
683
684 • Names used only within one module are of the form module*name.
685
686 • Names used outside the module in which they are defined are of the
687 form module@name.
688
689 • Names associated with a particular environment are of the form
690 environment:name; these are used only within the par module.
691
692 • name does not have a module prefix.
693
694 • Constructed names used to implement arrays are of the form
695 array!index.
696
697 Thus the groff ms macros reserve the following names:
698
699 • Names containing the characters *, @, and :.
700
701 • Names containing only uppercase letters and digits.
