Re: [Vim-latex-devel] label viewing

[Srinath A. <sr...@fa...>]

Hey Mikolaj,

I was actually thinking of a different way of implementing this... (I
haven't even started)... Here's my take:

call IMAP('\ref{', "\<C-o>:Tex_ListLabels()\<CR>", 'tex')

And Tex_ListLabels() should actually do something like:

function! Tex_ListLabels()
=09" We want to search labels across files... not just the current
=09" file... We might cache this in some manner so we don't end up
=09" spawning shell commands every time the user does \label...
=09silent! grep \\label{ *.tex
=09" Open up a window showing the matches... This lets us use vim's own
=09" excellent quickfix capabilities.
=09cclose
=09cwindow 5
=09" At this point we might even do something similar to what is done
=09" in RunLatex()... Open up the file corresponding to this match in a
=09" preview window...
=09wincmd p
endfunction

And if possible, we should make this function behave like RunLatex() so
that it also opens up the corresponding file in preview mode when we are
on a line in the cwindow... (So that we have some context aroudnd the
\label) Hope you are getting what I mean... Try making some $\mistake$
in a tex file and compiling it... I was thinking that the label/citation
browser would behave similarly...

What do you think?
