brace in alias name and compsys

brace in alias name and compsys

[Phil Pennock]

Given this:

    % alias ztrace{='() { setopt localoptions xtrace; '

I can do this:

    % ztrace{ [[ a == 43 ]] } 
    +(anon):0> [[ a == 43 ]]
    %

However, tab-completing 'ztrace{' yields 'ztrace\{'.  Hitting return on
a line with the backslash in it yields a:

    zsh: command not found: ztrace{

and a 127 exit status.

Working from "zsh -f", initially tab-completion yields "ztrace{" without
the backslash and everything works fine, but all it takes to get the
broken completion behaviour back is:

    % autoload compinit ; compinit

So this isn't anything in my grotesquery of a configuration and appears
to be straight from compsys.

Is there anything I can tune to change the completion behaviour to not
insert the extraneous backslash?

Thanks,
-Phil

This is coming directly from "compadd -k aliases" which in turn is
hardwired in the "defs" array in _command_names.

There's a similar problem with e.g. completing the builtin "!" "command".
It always gets turned into "\!" instead.

Can anyone think of a situation in which the following is wrong?

   )


While we're on the subject, completing after "[" or "[[" in command
position (no intervening whitespace) incorrectly attempts subscript
completion.  This appears to be a bug somewhere in the internals,
because compstate[context] has been set to 'subscript' and there's no
assignment to that in _complete_debug output.

Aside:  Zsh is unique, I think, in allowing alias names to contain
characters that are not legal in identifiers.
