Re: custom completion for listing *.tex is not working

[Leonardo Barbosa <barbosa.leonardo@gmail.com>]

Thanks for you prompt answer, Bart. I have tried your suggestion.
zstyle ':completion:*:*:vi:*' file-patterns '*.tex:TeX-files' '%p:all-files'


However, by doing so, it only through TeX files. So if <tab> multiples
times it keeps suggesting the same TeX files, repeatedly, to me. I'd
like TeX files to be priority, but, in case of more <tab>'s, it cycles
through other files in the menu, too.

I saw you example is similar to this example in the zsh manual:
zstyle ':completion:*:*:rm:*' file-patterns \ '*.o:object-files' '%p:all-files'

So in theory, it should have worked. Any idea?

An just one more question, how can i make zsh to highlight the
selected file in the menu while cycling through files?

Best

Leo
