Edit File: 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 can be 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, ^g to # abort back to the state when you started, and ^d to list the matches. # # This works only with the new function based completion system. # Recommended settings: # zstyle ':completion:incremental:*' completer _complete _ignored # zstyle :incremental stop-keys $'[\e\C-b\C-f\C-n\C-p\C-u-\C-x]' # BUGS: # The _oldlist completer breaks incremental completion. Use a context- # specific completer zstyle as shown above to disable the _oldlist # completer in this function. # The main widget function. incremental-complete-word() { emulate -L zsh unsetopt autolist menucomplete automenu # doesn't work well local key lbuf="$LBUFFER" rbuf="$RBUFFER" pmpt pstr word local lastl lastr wid twid num post toolong local curcontext="${curcontext}" stop brk [[ -z "$curcontext" ]] && curcontext=::: curcontext="incremental:${curcontext#*:}" zstyle -s ":incremental" prompt pmpt || pmpt='incremental (%c): %u%s %l' zstyle -s ":incremental" stop-keys stop zstyle -s ":incremental" break-keys brk if zstyle -t ":incremental" list; then wid=list-choices post=( icw-list-helper ) else wid=complete-word post=() fi comppostfuncs=( "$post[@]" ) zle $wid "$@" LBUFFER="$lbuf" RBUFFER="$rbuf" num=$_lastcomp[nmatches] if (( ! num )); then word='' state='-no match-' elif [[ "${LBUFFER}${RBUFFER}" = *${_lastcomp[unambiguous]}* ]]; then word='' state='-no prefix-' else word="${_lastcomp[unambiguous]}" state='' fi zformat -f pstr "$pmpt" "u:${word}" "s:$state" "n:$num" \ "l:$toolong" "c:${_lastcomp[completer]}" zle -R "$pstr" read -k key while [[ '#key' -ne '#\\r' && '#key' -ne '#\\n' && '#key' -ne '#\\C-g' ]]; do twid=$wid if [[ "$key" = ${~stop} ]]; then zle -U "$key" return elif [[ "$key" = ${~brk} ]]; then return elif [[ '#key' -eq '#\\C-h' || '#key' -eq '#\\C-?' ]]; then [[ $#LBUFFER -gt $#l ]] && LBUFFER="$LBUFFER[1,-2]" elif [[ '#key' -eq '#\\t' ]]; then zle complete-word "$@" lbuf="$LBUFFER" rbuf="$RBUFFER" elif [[ '#key' -eq '#\\C-d' ]]; then twid=list-choices else LBUFFER="$LBUFFER$key" fi if (( !
