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
16 The options are as follows:
17
18 +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
25 -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
29 -n Turn off backup file generation.
30
31 -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
40 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
44 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
55 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.

193 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
208 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
212 audible-bell

214
215 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
221 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
226 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
231 back-to-indentation
232 Move the dot to the first non-whitespace character on the current
233 line.
234

261 ets, and braces, the character itself is used as its own match.
262
263 bsmap-mode
264 Toggle bsmap mode, where DEL and C-h are swapped.
265
266 c-mode
267 Toggle a KNF-compliant mode for editing C program files.

332 Create cscope's List and Index in the given directory.
333
334 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
338 delete-backward-char
339 Delete backwards n characters. Like delete-char, this actually
340 does a kill if presented with an argument.
341
342 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
348 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
352 delete-horizontal-space
353 Delete any whitespace around the dot.
354
355 delete-leading-space
356 Delete leading whitespace on the current line.

377 *help* buffer.
378
379 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
383 diff-buffer-with-file
384 View the differences between buffer and its associated file.
385

418 expressions in mg startup files.
419
420 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
424 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
431 fill-paragraph
432 Justify a paragraph, wrapping text at the current fill column.
433
434 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
440 find-file-read-only
441 Same as find-file, except the new buffer is set to read-only.
442
443 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
449 find-file-other-window
450 Opens the specified file in a second buffer. Splits the current
451 window if necessary.

461 Move forward n paragraphs. Paragraphs are delimited by <NL><NL>
462 or <NL><TAB> or <NL><SPACE>.
463
464 forward-word
465 Move the cursor forward by the specified number of words.
466
467 global-set-key
468 Bind a key in the global (fundamental) key map.

471 Unbind a key from the global (fundamental) key map; i.e. set it to
472 'rescan'.
473
474 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
480 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
484 help-help
485 Prompts for one of (a)propos, (b)indings, des(c)ribe key briefly.
486
487 insert
488 Insert a string, mainly for use from macros.
489
490 insert-buffer

492
493 insert-file
494 Insert a file into the current buffer at dot.
495
496 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
500 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
506 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
512 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
516 just-one-space
517 Delete any whitespace around dot, then insert a space.
518
519 keyboard-quit
520 Abort the current action.
521
522 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
527 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
536 kill-paragraph
537 Delete n paragraphs starting with the current one.
538
539 kill-region
540 Kill the currently defined region.
541
542 kill-word
543 Delete forward n words.
544
545 leave-tmpdir-backups

573 Mark n paragraphs.
574
575 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
579 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
583 negative-argument
584 Process a negative argument for keyboard-invoked functions.
585
586 newline
587 Insert a newline into the current buffer.
588

591 indentation of the previous line. Assumes tabs are every eight
592 characters.
593
594 next-line
595 Move forward n lines.
596
597 not-modified
598 Turn off the modified flag in the current buffer.

602 back up over them.
603
604 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
609 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
614 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
618 previous-line
619 Move backwards n lines.
620
621 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.

643 using regular expressions for both patterns.
644
645 quoted-insert
646 Insert the next character verbatim into the current buffer; i.e.
647 ignore any function bound to that key.
648
649 re-search-again
650 Perform a regular expression search again, using the same search
651 string and direction as the last search command.
652
653 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
660 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
666 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.

711 search-again
712 Search again, using the same search string and direction as the
713 last search command.

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
841 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.

870
872 The following are a list of the commands specific to dired mode:
873
874 dired-create-directory
875 Create a directory.
876
877 dired-do-copy
878 Copy the file listed on the current line of the dired buffer.
879
880 dired-do-flagged-delete
881 Delete the files that have been flagged for deletion.
882
883 dired-do-rename
884 Rename the file listed on the current line of the dired buffer.
885
886 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
890 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
894 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
900 dired-find-file-other-window
901 Open the file on the current line of the dired buffer in a dif‐
902 ferent window.
903
904 dired-next-line
905 Move the cursor to the next line.
906
907 dired-other-window
908 This function works just like dired, except that it puts the
909 dired buffer in another window.
910
911 dired-previous-line
912 Move the cursor to the previous line.
913
914 dired-revert
915 Refresh the dired buffer.
916
917 dired-scroll-down
918 Scroll down the dired buffer.
919
920 dired-scroll-up
921 Scroll up the dired buffer.
922
923 dired-unmark
924 Remove the deletion flag for the file on the current line.
925
926 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
930 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
939 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
943 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
950 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
967 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
970 Multi-byte character sets, such as UTF-8, are not supported.
