;;; Commentary:
;; `hippie-expand' is a single function for a lot of different kinds
;; of completions and expansions. Called repeatedly it tries all
-;; possible completions in succession.
+;; possible completions in succession.
;; Which kinds of completions to try, and in which order, is
;; determined by the contents of `hippie-expand-try-functions-list'.
;; Much customization of `hippie-expand' can be made by changing the
;; matching buffer names (as strings) or major modes (as atoms) of
;; buffers that should not be searched by the try-functions named
;; "-all-buffers".
+;; If set, the variable `hippie-expand-only-buffers' does the opposite
+;; of `hippie-expand-ignore-buffers', in that the search is restricted
+;; to only the kind of buffers listed.
+;; If the variable `hippie-expand-no-restriction' is non-nil, narrowed
+;; buffers are widened before they are searched.
+;; The variable `hippie-expand-dabbrev-skip-space' controls whether
+;; trailing spaces will be included in the abbreviation to search for,
+;; which then gives the same behavior as the original `dabbrev-expand'.
+;; The variable `hippie-expand-dabbrev-as-symbol' controls whether
+;; characters of syntax '_' is considered part of the words to expand
+;; dynamically.
;; See also the macro `make-hippie-expand-function' below.
-;;
+;;
;; A short description of the current try-functions in this file:
;; `try-complete-file-name' : very convenient to have in any buffer,
;; and not just in the minibuffer or (some) shell-mode. It goes
;; a file name completed only as many characters as is unique.
;; `try-expand-all-abbrevs' : can be removed if you don't use abbrevs.
;; Otherwise it looks through all abbrev-tables, starting with
-;; the local followed by the global.
-;; `try-expand-line' : Searches the buffer for an entire line that
-;; begins exactly as the current line. Convenient sometimes, for
+;; the local followed by the global.
+;; `try-expand-line' : Searches the buffer for an entire line that
+;; begins exactly as the current line. Convenient sometimes, for
;; example as a substitute for (or complement to) the history
;; list in shell-like buffers. At other times, only confusing.
;; `try-expand-line-all-buffers' : Like `try-expand-line' but searches
;; `try-expand-list' : Tries to expand the text back to the nearest
;; open delimiter, to a whole list from the buffer. Convenient for
;; example when writing lisp or TeX.
-;; `try-expand-list-all-buffers' : Like `try-expand-list' but searches
-;; in all buffers (except the current).
+;; `try-expand-list-all-buffers' : Like `try-expand-list' but searches
+;; in all buffers (except the current).
;; `try-expand-dabbrev' : works exactly as dabbrev-expand (but of
;; course in a way compatible with the other try-functions).
;; `try-expand-dabbrev-all-buffers' : perhaps the most useful of them,
;; like `dabbrev-expand' but searches all Emacs buffers (except the
;; current) for matching words. (No, I don't find this one
-;; particularly slow.)
+;; particularly slow.)
;; `try-expand-dabbrev-visible': Searches the currently visible parts of
;; all windows. Can be put before `try-expand-dabbrev-all-buffers' to
;; first try the expansions you can see.
;; already has a key of its own, you might want to remove this.
;; `try-complete-lisp-symbol-partially' : To insert in the list just
;; before `try-complete-lisp-symbol' for those who first want to get
-;; completion of what is unique in the name.
+;; completion of what is unique in the name.
;;
;; Not all of the above functions are by default in
;; `hippie-expand-try-functions-list'. This variable is better set
;; `he-reset-string' : Resets the initialized region to its original
;; contents.
;; There is also a variable: `he-tried-table' which is meant to contain
-;; all tried expansions so far. The try-function can check this
+;; all tried expansions so far. The try-function can check this
;; variable to see whether an expansion has already been tried
;; (hint: `he-string-member').
;;
;; Known bugs
;;
;; It may happen that some completion suggestion occurs twice, in
-;; spite of the use of `he-tried-table' to prevent that. This is
+;; spite of the use of `he-tried-table' to prevent that. This is
;; because different try-functions may try to complete different
;; lengths of text, and thus put different amounts of the
;; text in `he-tried-table'. Anyway this seems to occur seldom enough
