ever-expanding ZLS_COLORS

ever-expanding ZLS_COLORS

[Matthew Lovell]

Hi,

I got the following style command from this list a little while ago.
It was given as an example of colored completion.

    zstyle ':completion:*:zsh-options' \
           list-colors '=csh*=31:=*hist*=32:=list*=34:=*glob*=35'

Now, everytime I attempt a completion which uses zsh-options, it seems
ZLS_COLORS just continues to grow:

No completion:
 di=33

After first completion:
 (zsh-options)=csh*=31:=*hist*=32:=list*=34:=*glob*=35:(zsh-options)\
 =csh*=31:=*hist*=32:=list*=34:=*glob*=35:di=33

After second completion:
 (zsh-options)=csh*=31:=*hist*=32:=list*=34:=*glob*=35:(zsh-options)\
 =csh*=31:=*hist*=32:=list*=34:=*glob*=35:(zsh-options)=csh*=31:=*hist*=32:\
 =list*=34:=*glob*=35:di=33
 

Eventually, ZLS_COLORS grows too long for whatever processing is done
(I think awk ends up complaining).  Is there something I can do to
prevent this behavior?

Thanks,
  Matt

Yes, I was noticing this myself.  It's happening because some code at the
top of the _setup function tries to merge your list-colors style with the
existing global value of $ZLS_COLORS, but then the old value of $ZLS_COLORS
doesn't get automatically restored when completion is done (the code to do
the restore in _main_complete is conditional upon $compstate[old_list]).

The best workaround for the time being is to assign to ZLS_COLORS in your
precmd function.  If you don't already have a precmd, it'd look like this:

    function precmd() {
	ZLS_COLORS='di=33'
    }

Otherwise just add that assignment to whatever you already have in precmd.
