;; Extended completion for the Emacs minibuffer.
|
|
|
|
|
;;
|
|
|
|
|
;; The basic idea is that the command name or other completable text is
|
|
|
|
|
;; divided into words and each word is completed separately, so that
|
|
|
|
|
;; "M-x p-b" expands to "M-x print-buffer". If the entry is ambiguous
|
|
|
|
|
;; each word is completed as much as possible and then the cursor is
|
|
|
|
|
;; left at the first position where typing another letter will resolve
|
|
|
|
|
;; the ambiguity.
|
|
|
|
|
;;
|
|
|
|
|
;; Word separators for this purpose are hyphen, space, and period.
|
|
|
|
|
;; These would most likely occur in command names, Info menu items,
|
|
|
|
|
;; and file names, respectively. But all word separators are treated
|
|
|
|
|
;; alike at all times.
|
|
|
|
|
;;
|
|
|
|
|
;; This completion package replaces the old-style completer's key
|
|
|
|
|
;; bindings for TAB, SPC, RET, and `?'. The old completer is still
|
|
|
|
|
;; available on the Meta versions of those keys. If you set
|
|
|
|
|
;; PC-meta-flag to nil, the old completion keys will be left alone
|
|
|
|
|
;; and the partial completer will use the Meta versions of the keys.

|
|
|
|
|
;; As an extra feature, in cases where RET would not normally
|
|
|
|
|
;; complete (such as `C-x b'), the M-RET key will always do a partial
|
|
|
|
|
;; complete-and-exit. Thus `C-x b f.c RET' will select or create a
|
|
|
|
|
;; buffer called "f.c", but `C-x b f.c M-RET' will select the existing
|
|
|
|
|
;; buffer whose name matches that pattern (perhaps "filing.c").
|
|
|
|
|
;; (PC-meta-flag does not affect this behavior; M-RET used to be
|
|
|
|
|
;; undefined in this situation.)
|
|
|

|

|
;; The regular M-TAB (lisp-complete-symbol) command also supports
|
|
|
|
|
;; partial completion in this package.
|
|
|
|
|
|
|
|
|
|
;; In addition, this package includes a feature for accessing include
|
|
|
|
|
;; files. For example, `C-x C-f <sys/time.h> RET' reads the file
|

When Partial Completion mode is enabled, TAB (or M-TAB if `PC-meta-flag' is

For example, M-x p-c-m expands to M-x partial-completion-mode since no other

|
|
|

\\[find-file] f_b.c TAB might complete to foo_bar.c if that file existed and no
