suffix aliases behaving weird?

suffix aliases behaving weird?

[Frank Terbeck]

Hi list!

Consider the following:

[snip]
  % alias -s ogg='ogg123'
  % /mnt/audio/music/S/Slayer\ -\ South\ Of\ Heaven\ -\ 01\ -\ South\ Of\ Heaven.ogg
      [plays fine]
  % "/mnt/audio/music/S/Slayer - South Of Heaven - 01 - South Of Heaven.ogg"
  zsh: permission denied: /mnt/audio/music/S/Slayer - South Of Heaven - 01 - South Of Heaven.ogg
[snap]

Bug or intended behaviour?

Regards, Frank

That's how aliases work: they're handled very early, before processing
of quotes, so it looks like the suffix is `ogg"'.  If you use
backslashes you won't have that problem.  Completion used to convert
automatically to backslashed form but it doesn't any more (I think I've
bitten off my than I can chew here, actually, but I can't put my finger
on exactly how it happened anyway).  With 4.3 the following ZLE widget
will do it:

backslashify() {
    modify-current-argument '${(q)${(Q)ARG}}'
}
autoload -U modify-current-argument
zle -N backslashify

Hm, and since that is the first thing mentioned in zshexpn(1), I
should probably read before babbling about maybe-bugs. :-)

Thanks, for pointing it out, Peter. :)
