34 ;; The `C-x C-k' (`edit-kbd-macro') command edits a keyboard macro
|
|
|
35 ;; in a special buffer. It prompts you to type a key sequence,
|
|
|
36 ;; which should be one of:
|
|
|
37 ;;
|
|
|
38 ;; * RET or `C-x e' (call-last-kbd-macro), to edit the most
|
|
|
39 ;; recently defined keyboard macro.
|
|
|
40 ;;
|
|
|
41 ;; * `M-x' followed by a command name, to edit a named command
|
|
|
42 ;; whose definition is a keyboard macro.
|
|
|
43 ;;
|
|
|
44 ;; * `C-h l' (view-lossage), to edit the 100 most recent keystrokes
|
|
|
45 ;; and install them as the "current" macro.
|
|
|
46 ;;
|
|
|
47 ;; * any key sequence whose definition is a keyboard macro.
|
|
|
48 ;;
|
|
|
49 ;; This file includes a version of `insert-kbd-macro' that uses the
|
|
|
50 ;; more readable format defined by these routines.
|
|
|
51 ;;
|
|
|
52 ;; Also, the `read-kbd-macro' command parses the region as
|
|
|
53 ;; a keyboard macro, and installs it as the "current" macro.
|
|
|
54 ;; This and `format-kbd-macro' can also be called directly as
|
|
|
55 ;; Lisp functions.
|
|
|
56
|
|
|
57 ;; Type `C-h m', or see the documentation for `edmacro-mode' below,
|
|
|
58 ;; for information about the format of written keyboard macros.
|
|
|
59
|
|
|
60 ;; `edit-kbd-macro' formats the macro with one command per line,
|
|
|
61 ;; including the command names as comments on the right. If the
|
|
|
62 ;; formatter gets confused about which keymap was used for the
|
|
|
63 ;; characters, the command-name comments will be wrong but that
|
|
|
64 ;; won't hurt anything.
|
|
|
65
|
|
|
66 ;; With a prefix argument, `edit-kbd-macro' will format the
|
|
|
67 ;; macro in a more concise way that omits the comments.
|
|
|
68
|
|
|
69 ;; This package requires GNU Emacs 19 or later, and daveg's CL
|
|
|
70 ;; package 2.02 or later. (CL 2.02 comes standard starting with
|
|
|
71 ;; Emacs 19.18.) This package does not work with Emacs 18 or

|
328 \"Key:\" lines at the top. These are followed by a \"Macro:\" line
|
|
|
329 and the macro itself as spelled-out keystrokes: `C-x C-f foo RET'.
|
|
|
330
|
|
|
331 The \"Command:\" line specifies the command name to which the macro
|
|
|
332 is bound, or \"none\" for no command name. Write \"last-kbd-macro\"
|
|
|
333 to refer to the current keyboard macro (as used by \\[call-last-kbd-macro]).
|
|
|
334
|
|
|
335 The \"Key:\" lines specify key sequences to which the macro is bound,
|
|
|
336 or \"none\" for no key bindings.
|
|
|
337
|
|
|
338 You can edit these lines to change the places where the new macro
|
|
|
339 is stored.
|
|
|
340
|
|
|
341
|
|
|
342 Format of keyboard macros during editing:
|
|
|
343
|
|
|
344 Text is divided into \"words\" separated by whitespace. Except for
|
|
|
345 the words described below, the characters of each word go directly
|
|
|
346 as characters of the macro. The whitespace that separates words
|
|
|
347 is ignored. Whitespace in the macro must be written explicitly,
|
|
|
348 as in \"foo SPC bar RET\".
|
|
|
349
|
|
|
350 * The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent
|
|
|
351 special control characters. The words must be written in uppercase.
|
|
|
352
|
|
|
353 * A word in angle brackets, e.g., <return>, <down>, or <f1>, represents
|
|
|
354 a function key. (Note that in the standard configuration, the
|
|
|
355 function key <return> and the control key RET are synonymous.)
|
|
|
356 You can use angle brackets on the words RET, SPC, etc., but they
|
|
|
357 are not required there.
|
|
|
358
|
|
|
359 * Keys can be written by their ASCII code, using a backslash followed
|
|
|
360 by up to six octal digits. This is the only way to represent keys
|
|
|
361 with codes above \\377.
|
|
|
362
|
|
|
363 * One or more prefixes M- (meta), C- (control), S- (shift), A- (alt),
|
|
|
364 H- (hyper), and s- (super) may precede a character or key notation.
|
|
|
365 For function keys, the prefixes may go inside or outside of the
|
|
|
366 brackets: C-<down> = <C-down>. The prefixes may be written in
|
|
|
367 any order: M-C-x = C-M-x.
|
|
|
368
|
|
|
369 Prefixes are not allowed on multi-key words, e.g., C-abc, except
|
|
|
370 that the Meta prefix is allowed on a sequence of digits and optional
|
|
|
371 minus sign: M--123 = M-- M-1 M-2 M-3.
|
|
|
372
|
|
|
373 * The `^' notation for control characters also works: ^M = C-m.
|
|
|
374
|
|
|
375 * Double angle brackets enclose command names: <<next-line>> is
|
|
|
376 shorthand for M-x next-line RET.
|
|
|
377
|
|
|
378 * Finally, REM or ;; causes the rest of the line to be ignored as a
|
|
|
379 comment.
|
|
|
380
|
|
|
381 Any word may be prefixed by a multiplier in the form of a decimal
|
|
|
382 number and `*': 3*<right> = <right> <right> <right>, and
|
|
|
383 10*foo = foofoofoofoofoofoofoofoofoofoo.
|
|
|
384
|
|
|
385 Multiple text keys can normally be strung together to form a word,
|
|
|
386 but you may need to add whitespace if the word would look like one
|
|
|
387 of the above notations: `; ; ;' is a keyboard macro with three
|
|
|
388 semicolons, but `;;;' is a comment. Likewise, `\\ 1 2 3' is four
|
|
|
389 keys but `\\123' is a single key written in octal, and `< right >'
|
|
|
390 is seven keys but `<right>' is a single function key. When in
|
|
|
391 doubt, use whitespace."
