Ignore patterns for alias

Ignore patterns for alias

[Sebastian Blask]

Hi,

I was trying to ignore some files during completion like this:

zstyle ':completion:*:*:vim:*:*files' ignored-patterns '*.pyc'

and could not get it to work. After a while i figured out that it's 
because I use scm-breeze which aliases vim so it accepts indexes:

$ which vim
vim: aliased to exec_scmb_expand_args /usr/bin/vim

I tried

zstyle ':completion:*:*:exec_scmb_expand_args:*:*files' ignored-patterns 
'*.pyc'

which ignores the files, but as there are others aliases for rm, mv, ... 
it is not specific enough. Something like:

zstyle ':completion:*:*:exec_scmb_expand_args:/usr/bin/vim:*files' 
ignored-patterns '*.pyc'

does not work at all.

Is this the expected behaviour? I expected completions to work on what 
is actually written on the command line and not on what it is aliased 
to. Is there a way to get it to work? Ideally so that this:

zstyle ':completion:*:*:vim:*:*files' ignored-patterns '*.pyc'

works out of the box?

Thanks!

You can get this to work with

compdef _precommand exec_smb_expand_args

which tells it that that's a precommand modifier and it should look
further along for the command to complete.  Then any alias using
that command will spring into life.

Unless you have a lot of these, that's probably less work than
telling it to use aliases as a basis for completion and then ensuring
you have a completion for all your aliases,  However, the option
COMPLETE_ALIASES is also available.
