4 mg — emacs-like text editor
5
7 mg [-nR] [-f mode] [+number] [file ...]
8
10 mg is intended to be a small, fast, and portable editor for people who
11 can't (or don't want to) run emacs for one reason or another, or are not
12 familiar with the vi(1) editor. It is compatible with emacs because
13 there shouldn't be any reason to learn more editor types than emacs or
14 vi(1).
15 The options are as follows:
17 +number
19 Go to the line specified by number (do not insert a space between
20 the ‘+’ sign and the number). If a negative number is specified,
21 the line number counts backwards from the end of the file i.e.
22 +-1 will be the last line of the file, +-2 will be second last,
23 and so on.
24 -f mode
26 Run the mode command for all buffers created from arguments on
27 the command line, including the scratch buffer and all files.
28 -n Turn off backup file generation.
30 -R Files specified on the command line will be opened read-only.
32
34 When a file is loaded into mg, it is stored in a buffer. This buffer may
35 be displayed on the screen in more than one window. At present, windows
36 may only be split horizontally, so each window is delineated by a mode‐
37 line at the bottom. If changes are made to a buffer, it will be
38 reflected in all open windows.
39 If a file is changed outside mg and its buffer is about to be changed, mg
41 prompts if the change should go ahead (y), not go ahead (n) or if the
42 buffer should be reverted (r) to the latest file on disk.
43 If a buffer name begins and ends with an asterisk, the buffer is consid‐
45 ered throwaway; i.e. the user will not be prompted to save changes when
46 the buffer is killed.
47
49 The current cursor location in mg is called the point (or dot). It is
50 possible to define a window-specific region of text by setting a second
51 location, called the mark. The region is the text between point and mark
52 inclusive. Deleting the character at the mark position leaves the mark
53 at the point of deletion.
54 Note: The point and mark are window-specific in mg, not buffer-specific,
56 as in other emacs flavours.
57
59 Backup files have a ‘~’ character appended to the file name and are cre‐
60 ated in the current working directory by default. Whether to create
61 backup files or not can be toggled with the make-backup-files command.
62 The backup file location can either be in the current working directory,
63 or all backups can be moved to a ~/.mg.d directory where files retain
64 their path name to retain uniqueness. Use the backup-to-home-directory
65 to alternate between these two locations. Further, if any application
66 creates backup files in /tmp, these can be left with the leave-tmpdir-
67 backups command.
68
70 mg supports tag files created by ctags(1), allowing the user to quickly
71 locate various object definitions. Note though that emacs uses etags,
72 not ctags.
73
75 mg supports navigating source code using cscope. However, mg requires
76 cscope and cscope-indexer executables to be present in PATH for it to
77 work.
78
80 Normal editing commands are very similar to GNU Emacs. In the following
81 examples, C-x means Control-x, and M-x means Meta-x, where the Meta key
82 may be either a special key on the keyboard or the ALT key; otherwise ESC
83 followed by the key X works as well.

192 For a complete description of mg commands, see MG COMMANDS. To see the
194 active keybindings at any time, type “M-x describe-bindings”.
195
197 Commands are invoked by “M-x”, or by binding to a key. Many commands
198 take an optional numerical parameter, n. This parameter is set either by
199 M-<n> (where n is the numerical argument) before the command, or by one
200 or more invocations of the universal argument, usually bound to C-u.
201 When invoked in this manner, the value of the numeric parameter to be
202 passed is displayed in the minibuffer before the M-x. One common use of
203 the parameter is in mode toggles (e.g. make-backup-files). If no parame‐
204 ter is supplied, the mode is toggled to its alternate state. If a posi‐
205 tive parameter is supplied, the mode is forced to on. Otherwise, it is
206 forced to off.
207 apropos
209 Help Apropos. Prompt the user for a string, open the *help* buf‐
210 fer, and list all mg commands that contain that string.
211 audible-bell
213 Toggle the audible system bell.
214 auto-execute
216 Register an auto-execute hook; that is, specify a filename pattern
217 (conforming to the shell's filename globbing rules) and an associ‐
218 ated function to execute when a file matching the specified pat‐
219 tern is read into a buffer.
220 auto-fill-mode
222 Toggle auto-fill mode (sometimes called mail-mode) in the current
223 buffer, where text inserted past the fill column is automatically
224 wrapped to a new line. Can be set globally with set-default-mode.
225 auto-indent-mode
227 Toggle indent mode in the current buffer, where indentation is
228 preserved after a newline. Can be set globally with set-default-
229 mode.
230 back-to-indentation
232 Move the dot to the first non-whitespace character on the current
233 line.
234 backup-to-home-directory
236 Save backup copies to a ~/.mg.d directory instead of working
237 directory. Requires make-backup-files to be on.
238 backward-char
240 Move cursor backwards one character.
241 backward-kill-word
243 Kill text backwards by n words.
244 backward-paragraph

247 <NL><NL> or <NL><TAB> or <NL><SPACE>.
248 backward-word
250 Move cursor backwards by the specified number of words.
251 beginning-of-buffer
253 Move cursor to the top of the buffer.
254 beginning-of-line
256 Move cursor to the beginning of the line.
257 blink-and-insert
259 Self-insert a character, then search backwards and blink its
260 matching delimiter. For delimiters other than parenthesis, brack‐
261 ets, and braces, the character itself is used as its own match.
262 bsmap-mode
264 Toggle bsmap mode, where DEL and C-h are swapped.
265 c-mode
267 Toggle a KNF-compliant mode for editing C program files.
268 call-last-kbd-macro
270 Invoke the keyboard macro.
271 capitalize-word
273 Capitalize n words; i.e. convert the first character of the word
274 to upper case, and subsequent letters to lower case.
275 cd Change the global working directory. See also global-wd-mode.
277 column-number-mode
279 Toggle whether the column number is displayed in the modeline.
280 copy-region-as-kill
282 Copy all of the characters in the region to the kill buffer,
283 clearing the mark afterwards. This is a bit like a kill-region
284 followed by a yank.
285 count-matches
287 Count the number of lines matching the supplied regular expres‐
288 sion.
289 count-non-matches
291 Count the number of lines not matching the supplied regular
292 expression.

330 cscope-create-list-of-files-to-index
332 Create cscope's List and Index in the given directory.
333 define-key
335 Prompts the user for a named keymap (mode), a key, and an mg com‐
336 mand, then creates a keybinding in the appropriate map.
337 delete-backward-char
339 Delete backwards n characters. Like delete-char, this actually
340 does a kill if presented with an argument.
341 delete-blank-lines
343 Delete blank lines around dot. If dot is sitting on a blank line,
344 this command deletes all the blank lines above and below the cur‐
345 rent line. Otherwise, it deletes all of the blank lines after the
346 current line.
347 delete-char
349 Delete n characters forward. If any argument is present, it kills
350 rather than deletes, saving the result in the kill buffer.
351 delete-horizontal-space
353 Delete any whitespace around the dot.
354 delete-leading-space
356 Delete leading whitespace on the current line.
357 delete-trailing-space
359 Delete trailing whitespace on the current line.
360 delete-matching-lines
362 Delete all lines after dot that contain a string matching the sup‐
363 plied regular expression.
364 delete-non-matching-lines
366 Delete all lines after dot that don't contain a string matching
367 the supplied regular expression.
368 delete-other-windows
370 Make the current window the only window visible on the screen.
371 delete-window
373 Delete current window.
374 describe-bindings
376 List all global and local keybindings, putting the result in the
377 *help* buffer.
378 describe-key-briefly
380 Read a key from the keyboard, and look it up in the keymap. Dis‐
381 play the name of the function currently bound to the key.
382 diff-buffer-with-file
384 View the differences between buffer and its associated file.
385 digit-argument
387 Process a numerical argument for keyboard-invoked functions.
388 downcase-region
390 Set all characters in the region to lower case.
391 downcase-word
393 Set characters to lower case, starting at the dot, and ending n
394 words away.
395 emacs-version
397 Return an mg version string.
398 end-kbd-macro
400 Stop defining a keyboard macro.
401 end-of-buffer
403 Move cursor to the end of the buffer.
404 end-of-line
406 Move cursor to the end of the line.
407 enlarge-window
409 Enlarge the current window by shrinking either the window above or
410 below it.
411 eval-current-buffer
413 Evaluate the current buffer as a series of mg commands. Useful
414 for testing mg startup files.
415 eval-expression
417 Get one line from the user, and run it. Useful for testing
418 expressions in mg startup files.
419 exchange-point-and-mark
421 Swap the values of "dot" and "mark" in the current window. Return
422 an error if no mark is set.
423 execute-extended-command
425 Invoke an extended command; i.e. M-x. Call the message line rou‐
426 tine to read in the command name and apply autocompletion to it.
427 When it comes back, look the name up in the symbol table and run
428 the command if it is found, passing arguments as necessary. Print
429 an error if there is anything wrong.
430 fill-paragraph
432 Justify a paragraph, wrapping text at the current fill column.
433 find-file
435 Select a file for editing. First check if the file can be found
436 in another buffer; if it is there, just switch to that buffer. If
437 the file cannot be found, create a new buffer, read in the file
438 from disk, and switch to the new buffer.
439 find-file-read-only
441 Same as find-file, except the new buffer is set to read-only.
442 find-alternate-file
444 Replace the current file with an alternate one. Semantics for
445 finding the replacement file are the same as find-file, except the
446 current buffer is killed before the switch. If the kill fails, or
447 is aborted, revert to the original file.
448 find-file-other-window
450 Opens the specified file in a second buffer. Splits the current
451 window if necessary.
452 find-tag
454 Jump to definition of tag at dot.
455 forward-char
457 Move cursor forwards (or backwards, if n is negative) n charac‐
458 ters. Returns an error if the end of buffer is reached.
459 forward-paragraph
461 Move forward n paragraphs. Paragraphs are delimited by <NL><NL>
462 or <NL><TAB> or <NL><SPACE>.
463 forward-word
465 Move the cursor forward by the specified number of words.
466 global-set-key
468 Bind a key in the global (fundamental) key map.
469 global-unset-key
471 Unbind a key from the global (fundamental) key map; i.e. set it to
472 'rescan'.
473 global-wd-mode
475 Toggle global working-directory mode. When enabled, mg defaults
476 to opening files (and executing commands like compile and grep)
477 relative to the global working directory. When disabled, a work‐
478 ing directory is set for each buffer.
479 goto-line
481 Go to a specific line. If an argument is present, then it is the
482 line number, else prompt for a line number to use.
483 help-help
485 Prompts for one of (a)propos, (b)indings, des(c)ribe key briefly.
486 insert
488 Insert a string, mainly for use from macros.
489 insert-buffer
491 Insert the contents of another buffer at dot.
492 insert-file
494 Insert a file into the current buffer at dot.
495 insert-with-wrap
497 Insert the bound character with word wrap. Check to see if we're
498 past the fill column, and if so, justify this line.
499 isearch-backward
501 Use incremental searching, initially in the reverse direction.
502 isearch ignores any explicit arguments. If invoked during macro
503 definition or evaluation, the non-incremental search-backward is
504 invoked instead.
505 isearch-forward
507 Use incremental searching, initially in the forward direction.
508 isearch ignores any explicit arguments. If invoked during macro
509 definition or evaluation, the non-incremental search-forward is
510 invoked instead.
511 join-line
513 Join the current line to the previous. If called with an argu‐
514 ment, join the next line to the current one.
515 just-one-space
517 Delete any whitespace around dot, then insert a space.
518 keyboard-quit
520 Abort the current action.
521 kill-buffer
523 Dispose of a buffer, by name. If the buffer name does not start
524 and end with an asterisk, prompt the user if the buffer has been
525 changed.
526 kill-line
528 Kill line. If called without an argument, it kills from dot to
529 the end of the line, unless it is at the end of the line, when it
530 kills the newline. If called with an argument of 0, it kills from
531 the start of the line to dot. If called with a positive argument,
532 it kills from dot forward over that number of newlines. If called
533 with a negative argument it kills any text before dot on the cur‐
534 rent line, then it kills back abs(n) lines.
535 kill-paragraph
537 Delete n paragraphs starting with the current one.
538 kill-region
540 Kill the currently defined region.
541 kill-word
543 Delete forward n words.
544 leave-tmpdir-backups
546 Modifies the behaviour of backup-to-home-directory. Backup files
547 that would normally reside in /tmp are left there and not moved to
548 the ~/.mg.d directory.
549 line-number-mode
551 Toggle whether the line number is displayed in the modeline.
552 list-buffers
554 Display the list of available buffers.
555 load Prompt the user for a filename, and then execute commands from
557 that file.
558 local-set-key
560 Bind a key mapping in the local (topmost) mode.
561 local-unset-key
563 Unbind a key mapping in the local (topmost) mode.
564 make-backup-files
566 Toggle generation of backup files.
567 make-directory
569 Prompt the user for a path or directory name which is then cre‐
570 ated.
571 mark-paragraph
573 Mark n paragraphs.
574 mark-whole-buffer
576 Marks whole buffer as a region by putting dot at the beginning and
577 mark at the end of buffer.
578 meta-key-mode
580 When disabled, the meta key can be used to insert extended-ascii
581 (8-bit) characters. When enabled, the meta key acts as usual.
582 negative-argument
584 Process a negative argument for keyboard-invoked functions.
585 newline
587 Insert a newline into the current buffer.
588 newline-and-indent
590 Insert a newline, then enough tabs and spaces to duplicate the
591 indentation of the previous line. Assumes tabs are every eight
592 characters.
593 next-line
595 Move forward n lines.
596 not-modified
598 Turn off the modified flag in the current buffer.
599 open-line
601 Open up some blank space. Essentially, insert n newlines, then
602 back up over them.
603 other-window
605 The command to make the next (down the screen) window the current
606 window. There are no real errors, although the command does noth‐
607 ing if there is only 1 window on the screen.
608 overwrite-mode
610 Toggle overwrite mode in the current buffer, where typing over‐
611 writes existing characters rather than inserting them. Can be set
612 globally with set-default-mode.
613 prefix-region
615 Inserts a prefix string before each line of a region. The prefix
616 string is settable by using 'set-prefix-string'.
617 previous-line
619 Move backwards n lines.
620 previous-window
622 This command makes the previous (up the screen) window the current
623 window. There are no errors, although the command does not do a
624 lot if there is only 1 window.
625 pop-tag-mark
627 Return to position where find-tag was previously invoked.
628 push-shell
630 Suspend mg and switch to alternate screen, if available.
631 pwd Display current (global) working directory in the status area.
633 query-replace
635 Query Replace. Search and replace strings selectively, prompting
636 after each match.
637 replace-string
639 Replace string globally without individual prompting.
640 query-replace-regexp
642 Replace strings selectively. Does a search and replace operation
643 using regular expressions for both patterns.
644 quoted-insert
646 Insert the next character verbatim into the current buffer; i.e.
647 ignore any function bound to that key.
648 re-search-again
650 Perform a regular expression search again, using the same search
651 string and direction as the last search command.
652 re-search-backward
654 Search backwards using a regular expression. Get a search string
655 from the user, and search, starting at dot and proceeding toward
656 the front of the buffer. If found, dot is left pointing at the
657 first character of the pattern [the last character that was
658 matched].
659 re-search-forward
661 Search forward using a regular expression. Get a search string
662 from the user and search for it starting at dot. If found, move
663 dot to just after the matched characters. display does all the
664 hard stuff. If not found, it just prints a message.
665 recenter
667 Reposition dot in the current window. By default, the dot is cen‐
668 tered. If given a positive argument (n), the display is reposi‐
669 tioned to line n. If n is negative, it is that line from the bot‐
670 tom.
671 redraw-display
673 Refresh the display. Recomputes all window sizes in case some‐
674 thing has changed.
675 revert-buffer
677 Revert the current buffer to the latest file on disk.
678 save-buffer
680 Save the contents of the current buffer if it has been changed,
681 optionally creating a backup copy.
682 save-buffers-kill-emacs
684 Offer to save modified buffers and quit mg.
685 save-some-buffers
687 Look through the list of buffers, offering to save any buffer that
688 has been changed. Buffers that are not associated with files
689 (such as *scratch*, *grep*, *compile*) are ignored.
690 scroll-down
692 Scroll backwards n pages. A two-line overlap between pages is
693 assumed. If given a repeat argument, scrolls back lines, not
694 pages.
695 scroll-one-line-down
697 Scroll the display down n lines without changing the cursor posi‐
698 tion.
699 scroll-one-line-up
701 Scroll the display n lines up without moving the cursor position.
702 scroll-other-window
704 Scroll the next window in the window list window forward n pages.

713 last search command.
714 search-backward
716 Reverse search. Get a search string from the user, and search,

718 found, dot is left pointing at the first character of the pattern
719 (the last character that was matched).
720 search-forward

761 split-window-vertically
763 Split the current window. A window smaller than 3 lines cannot be
764 split.
765 start-kbd-macro

789 requested, the current paragraph will be moved n paragraphs for‐
790 ward.
791 transpose-words

796 vening command, move the undo pointer to the previous action and
797 undo it.
798 undo-boundary
800 Add an undo boundary. This is not usually done interactively.
801 undo-boundary-toggle
803 Toggle whether undo boundaries are generated. Undo boundaries are
804 often disabled before operations that should be considered atomi‐
805 cally undoable.
806 undo-enable
808 Toggle whether undo information is kept.
809 undo-list
811 Show the undo records for the current buffer in a new buffer.
812 universal-argument
814 Repeat the next command 4 times. Usually bound to C-u. This com‐
815 mand may be stacked; e.g. C-u C-u C-f moves the cursor forward 16
816 characters.
817 upcase-region
819 Upper case region. Change all of the lower case characters in the
820 region to upper case.
821 upcase-word
823 Move the cursor forward by the specified number of words. As it

834 Display a bunch of useful information about the current location
835 of dot. The character under the cursor (in octal), the current
836 line, row, and column, and approximate position of the cursor in
837 the file (as a percentage) is displayed. The column position
838 assumes an infinite position display; it does not truncate just
839 because the screen does.
840 write-file
842 Ask for a file name and write the contents of the current buffer
843 to that file. Update the remembered file name and clear the buf‐
844 fer changed flag.
845 yank Yank text from kill-buffer. Unlike emacs, the mg kill buffer con‐
847 sists only of the most recent kill. It is not a ring.

872 The following are a list of the commands specific to dired mode:
873 dired-create-directory
875 Create a directory.
876 dired-do-copy
878 Copy the file listed on the current line of the dired buffer.
879 dired-do-flagged-delete
881 Delete the files that have been flagged for deletion.
882 dired-do-rename
884 Rename the file listed on the current line of the dired buffer.
885 dired-find-alternate-file
887 Replace the current dired buffer with an alternate one as speci‐
888 fied by the position of the cursor in the dired buffer.
889 dired-find-file
891 Open the file on the current line of the dired buffer. If the
892 cursor is on a directory it will be opened in dired mode.
893 dired-flag-file-deletion
895 Flag the file listed on the current line for deletion. This is
896 indicated in the buffer by putting a D at the left margin. No
897 files are actually deleted until the function dired-do-flagged-
898 delete is executed.
899 dired-find-file-other-window
901 Open the file on the current line of the dired buffer in a dif‐
902 ferent window.
903 dired-next-line
905 Move the cursor to the next line.
906 dired-other-window
908 This function works just like dired, except that it puts the
909 dired buffer in another window.
910 dired-previous-line
912 Move the cursor to the previous line.
913 dired-revert
915 Refresh the dired buffer.
916 dired-scroll-down
918 Scroll down the dired buffer.
919 dired-scroll-up
921 Scroll up the dired buffer.
922 dired-unmark
924 Remove the deletion flag for the file on the current line.
925 dired-unmark-backward
927 Remove the deletion flag from the file listed on the previous
928 line of the dired buffer, then move up to that line.
929 quit-window
931 Close the current dired buffer.
932
934 There are two configuration files, .mg and .mg-TERM. Here, TERM repre‐
935 sents the name of the terminal type; e.g. if the terminal type is set to
936 “vt100”, mg will use .mg-vt100 as a startup file. The terminal type
937 startup file is used first.
938 The startup file format is a list of commands, one per line, as used for
940 interactive evaluation. Strings that are normally entered by the user at
941 any subsequent prompts may be specified after the command name; e.g.:
942 global-set-key ")" self-insert-command
944 global-set-key "\^x\^f" find-file
945 global-set-key "\e[Z" backward-char
946 set-default-mode fill
947 set-fill-column 72
948 auto-execute *.c c-mode
949 Comments can be added to the startup files by placing “;” or “#” as the
951 first character of a line.
952
954 ~/.mg normal startup file
955 ~/.mg-TERM terminal-specific startup file
956 ~/.mg.d alternative backup file location
957 /usr/share/doc/mg/tutorial concise tutorial
958
960 ctags(1), vi(1)
961
963 Since it is written completely in C, there is currently no language in
964 which extensions can be written; however, keys can be rebound and certain
965 parameters can be changed in startup files.
966 In order to use 8-bit characters (such as German umlauts), the Meta key
968 needs to be disabled via the “meta-key-mode” command.
969 Multi-byte character sets, such as UTF-8, are not supported.
