;;;; Completion.
;; This allows you to type part of a word, hit a special key, and have
;; the rest of the word filled in for you automagically.  ESC TAB attempts
;; to complete based on context, or from a user defined list of words;
;; a few other bindings will do more explicit completions.
;;
;; To use:  /load this file, and optionally store a list of words in
;; %{completion_list}.  For example, add this to your ~/.tfrc file:
;;
;;    /load complete.tf
;;    /set completion_list=Hawkeye TinyFugue tinyfugue.sourceforge.net
;;
;; Completion keys:
;;
;; ESC TAB	complete from context, input history, or %{completion_list}.
;; ESC ;	complete from %{completion_list}.
;; ESC i	complete from input history.
;; ESC /	filename completion (UNIX only).
;; ESC @	hostname completion.
;; ESC %	variable name completion.
;; ESC $	macro name completion.
;; ESC ^W	world name completion.

;; By "from context", I mean it will look for patterns and decide which
;; type of completion to use.  For example, if the line begins with "/load",
;; it will use filename completion; if the word begins with "%" or "%{", it
;; will use variable name completion; etc.

;; Optional user extensions.
;; To add your own completion, write a macro with a name like complete_foo
;; which takes the partial word as an argument, and calls /_complete_from_list
;; with the partial word and a list of possible matches.  Then bind a key
;; sequence that calls "/complete foo", and/or add a context
;; sensitive call in "/complete_context".
