expand-cmd-path

[Andy Spiegl]

Hi!

I am using 3.1.6-dev-16 and loving it!

While playing around with zle's "expand-cmd-path" I found that I'd like a
different behavior of it (similar to tcsh).  I'd prefer if it didn't expand
the first word/command on the input line, but the word before the cursor.
Is that possible somehow?

And I noticed that it does not expand aliases.  Is that intended?  Can it
be changed?

Thanks a lot,
 Andy.

Why not write your own little widget function? Like so:

  expand-last-word() {
    local word="${(M)LBUFFER%%[^ 	\;\|\{\}]##}" exp

    if (( $+commands[$word] )); then
      exp="$commands[$word]"
    elif (( $+aliases[$word] )); then
      exp="$aliases[$word]"
    fi

    [[ -n "$exp" ]] && LBUFFER="${LBUFFER%$word}$exp"
  }
  zle -N expand-last-word
  bindkey ... expand-last-word

Plus obvious improvements: The pattern in the first line should match
only thos characters that should be considered part of the word. If
the cursor is after a space (or other non-word characters) it could
search back for the word to expand. It could append a space to the
string inserted. Etc.

Bye
 Sven
