# smart-insert-last-word # Inspired by Christoph Lange from zsh-users/3265; # rewritten to correct multiple-call behavior after zsh-users/3270; # modified to work with copy-earlier-word after zsh-users/5832. # # This function as a ZLE widget can replace insert-last-word, like so: # # zle -N insert-last-word smart-insert-last-word # # With a numeric prefix, behaves like insert-last-word, except that words # in comments are ignored when interactive_comments is set. # # Otherwise, the rightmost "interesting" word from the previous command is # found and inserted. The default definition of "interesting" is that the # word contains at least one alphabetic character, slash, or backslash. # This definition can be overridden by use of a style like so: # # zstyle :insert-last-word match '*[[:alpha:]/\\]*' # # For example, you might want to include words that contain spaces: # # zstyle :insert-last-word match '*[[:alpha:][:space:]/\\]*' # # Or include numbers as long as the word is at least two characters long: # # zstyle :insert-last-word match '*([[:digit:]]?|[[:alpha:]/\\])*' # # That causes redirections like "2>" to be included. # # Note also that the style is looked up based on the widget name, so you # can bind this function to different widgets to use different patterns: # # zle -N insert-last-assignment smart-insert-last-word # zstyle :insert-last-assignment match '[[:alpha:]][][[:alnum:]]#=*' # bindkey '\e=' insert-last-assignment emulate -L zsh setopt extendedglob # Not strictly necessary: # (($+_ilw_hist)) || integer -g _ilw_hist _ilw_count _ilw_cursor _ilw_lcursor integer cursor=$CURSOR lcursor=$CURSOR local lastcmd pattern numeric=$NUMERIC # Save state for repeated calls if (( HISTNO == _ilw_hist && cursor == _ilw_cursor )); then NUMERIC=$[_ilw_count+1] lcursor=$_ilw_lcursor else NUMERIC=1 _ilw_lcursor=$lcursor fi # Handle the up to three arguments of .insert-last-word if (( $+1 )); then if (( $+3 )); then ((NUMERIC = -($1))) else ((NUMERIC = _ilw_count - $1)) fi (( NUMERIC )) || LBUFFER[lcursor+1,cursor+1]='' numeric=$((-(${2:--numeric}))) fi _ilw_hist=$HISTNO _ilw_count=$NUMERIC zle .up-history || return 1 # Retrieve previous command lastcmd=( ${${(z)BUFFER}:#\;} ) # Split into shell words zle .down-history # Return to current command CURSOR=$cursor # Restore cursor position NUMERIC=${numeric:-1} # In case of fall through (( NUMERIC > $#lastcmd )) && return 1 if [[ -z "$numeric" ]] then integer i=1 zstyle -s :$WIDGET match pattern || pattern='*[[:alpha:]/\\]*' while ((i <= $#lastcmd)); do if [[ $lastcmd[-i] == $~pattern ]]; then NUMERIC=$i break else ((++i)) fi done fi LBUFFER[lcursor+1,cursor+1]=$lastcmd[-NUMERIC] _ilw_cursor=$CURSOR
