# incremental-complete-word() {
|
|
|
|
# Autoload this function, run `zle -N <func-name>' and bind <func-name>
|
|
# to a key.
|
|
|
|
# This allows incremental completion of a word. After starting this
|
|
# command, a list of completion choices is shown after every character you
|
|
# type, which you can delete with ^h or DEL. RET will accept the
|
|
# completion so far. You can hit TAB to do normal completion and ^g to
|
|
# abort back to the state when you started.
|
|
#
|
|
# Completion keys:
|
|
# incremental_prompt Prompt to show in status line during icompletion;
|
|
# the sequence `%u' is replaced by the unambiguous
|
|
# part of all matches if there is any and it is
|
|
# different from the word on the line
|
|
# incremental_stop Pattern matching keys which will cause icompletion
|
|
# to stop and the key to be re-executed
|
|
# incremental_break Pattern matching keys which will cause icompletion
|
|
# to stop and the key to be discarded
|
|
# incremental_completer Set of completers, like the `completer' key
|
|
# incremental_list If set to a non-empty string, the matches will be
|
|
# listed on every key-press
