29 | ;; Extended completion for the Emacs minibuffer. | |
30 | ;; | |
31 | ;; The basic idea is that the command name or other completable text is | |
32 | ;; divided into words and each word is completed separately, so that | |
33 | ;; "M-x p-b" expands to "M-x print-buffer". If the entry is ambiguous | |
34 | ;; each word is completed as much as possible and then the cursor is | |
35 | ;; left at the first position where typing another letter will resolve | |
36 | ;; the ambiguity. | |
37 | ;; | |
38 | ;; Word separators for this purpose are hyphen, space, and period. | |
39 | ;; These would most likely occur in command names, Info menu items, | |
40 | ;; and file names, respectively. But all word separators are treated | |
41 | ;; alike at all times. | |
42 | ;; | |
43 | ;; This completion package replaces the old-style completer's key | |
44 | ;; bindings for TAB, SPC, RET, and `?'. The old completer is still | |
45 | ;; available on the Meta versions of those keys. If you set | |
46 | ;; PC-meta-flag to nil, the old completion keys will be left alone | |
47 | ;; and the partial completer will use the Meta versions of the keys. | |
48 | ||
49 | ||
7117761b | 50 | ;; Usage: M-x partial-completion-mode. During completable minibuffer entry, |
b545bfe6 JB |
51 | ;; |
52 | ;; TAB means to do a partial completion; | |
53 | ;; SPC means to do a partial complete-word; | |
54 | ;; RET means to do a partial complete-and-exit; | |
55 | ;; ? means to do a partial completion-help. | |
56 | ;; | |
57 | ;; If you set PC-meta-flag to nil, then TAB, SPC, RET, and ? perform | |
58 | ;; original Emacs completions, and M-TAB etc. do partial completion. | |
59 | ;; To do this, put the command, | |
60 | ;; | |
61 | ;; (setq PC-meta-flag nil) | |
62 | ;; | |
63 | ;; in your .emacs file. To load partial completion automatically, put | |
64 | ;; | |
7117761b | 65 | ;; (partial-completion-mode t) |
b545bfe6 JB |
66 | ;; |
67 | ;; in your .emacs file, too. Things will be faster if you byte-compile | |
68 | ;; this file when you install it. | |
69 | ;; | |
70 | ;; As an extra feature, in cases where RET would not normally | |
71 | ;; complete (such as `C-x b'), the M-RET key will always do a partial | |
72 | ;; complete-and-exit. Thus `C-x b f.c RET' will select or create a | |
73 | ;; buffer called "f.c", but `C-x b f.c M-RET' will select the existing | |
74 | ;; buffer whose name matches that pattern (perhaps "filing.c"). | |
75 | ;; (PC-meta-flag does not affect this behavior; M-RET used to be | |
76 | ;; undefined in this situation.) | |
77 | ;; | |
78 | ;; The regular M-TAB (lisp-complete-symbol) command also supports | |
79 | ;; partial completion in this package. | |
80 | ||
b545bfe6 JB |
81 | ;; In addition, this package includes a feature for accessing include |
82 | ;; files. For example, `C-x C-f <sys/time.h> RET' reads the file | |
83 | ;; /usr/include/sys/time.h. The variable PC-include-file-path is a | |
84 | ;; list of directories in which to search for include files. Completion | |
85 | ;; is supported in include file names. | |

191 | When Partial Completion mode is enabled, TAB (or M-TAB if `PC-meta-flag' is | |
192 | nil) is enhanced so that if some string is divided into words and each word is | |
193 | delimited by a character in `PC-word-delimiters', partial words are completed | |
194 | as much as possible and `*' characters are treated likewise in file names. | |
195 | ||
196 | For example, M-x p-c-m expands to M-x partial-completion-mode since no other | |
197 | command begins with that sequence of characters, and | |
198 | \\[find-file] f_b.c TAB might complete to foo_bar.c if that file existed and no | |

2ad432ab | 201 | Unless `PC-disable-includes' is non-nil, the `<...>' sequence is interpreted |
cc7e4da0 | 202 | specially in \\[find-file]. For example, |
2ad432ab | 203 | \\[find-file] <sys/time.h> RET finds the file `/usr/include/sys/time.h'. |

205 | ||
206 | Partial Completion mode extends the meaning of `completion-auto-help' (which | |
6c76000b RS |
207 | see), so that if it is neither nil nor t, Emacs shows the `*Completions*' |
208 | buffer only on the second attempt to complete. That is, if TAB finds nothing | |
209 | to complete, the first TAB just says \"Next char not unique\" and the | |
