[Vim-latex-devel] Viewer doesnt start in Ubuntu Dapper Drake

[Sebastian M. <seb...@un...>]

Hi all

I switched from Debian to Ubuntu recently. When i start gvim from the
file-browser (nautilus), "g:call Tex_ViewLaTeX()" (\lv), doesnt do
anything. When I start gvim from the shell everything works fine.

In /usr/share/vim/addons/ftplugin/texrc, I uncommented 

" TexLet g:Tex_ViewRuleComplete_dvi = ''

But that didnt help.

Version of latexsuite as reported by synaptic: 0.20041219-2
Version of vim: 6.4.6

Any suggestions?

Regards, Sebastian.

I do not have access to Ubuntu right now, but a guess is that in the two
cases, the $PATH variable is different so that in one case, the program
specified by g:Tex_ViewRule_dvi is not found while its found in the
other.

In your case, I am pretty sure the following should work:

:let g:Tex_ViewRule_dvi =3D '/usr/bin/xdvi'

and then do \lv. If you specify the complete path to your viewer, things
_should_ work.

g:Tex_ViewRuleComplete_dvi is to fix another problem i.e, when your
viewer needs to be called with a custom syntax.

This is a _really_ old version of latex-suite. I would recommend getting
the latest version directly from:

That is actually the version that Debian has packaged[1]. The package
is currently up for adoption, waiting for someone who knows what they
are doing to take over. Ubuntu has inherited the package straight from
Debian, out of date as it is.

Nope.

I understood that, but default was the empty string, and if I get it
right, that overwrites "g:Tex_ViewRule_dvi" !? Anyway, that's OT.

OK, I did so, but that didnt help either. 

Can give some suggestions how to debug it myself? I would like to see
what happens exactly when calling the view function. I guess that xdvi
dies out of some reason and vim/latexsuite doesnt sense that thinking
that

Thanks for offering to debug. Here are suggestions:

1. Put
        :let g:Tex_Debug =3D 1
   in your ~/.vim/ftplugin/tex.vim. And then press \lv. Then type:
        :call Tex_PrintDebug('comp')
   This should show a string like:
        Tex_ViewLaTeX: execString =3D xdvi "file.dvi" &
   Vim-Latex basically runs this string as:
        exec 'silent! !'.execString
   You can try running this without the silent! to see any error
   messages which might pop up. Type in exactly the string which is
   reported by Tex_ViewLaTeX. So, try
        :! xdvi "file.dvi" &
   from within vim to see what might be happening. This should give you
   a clue. The last command will be the most informative. It should tell
   you if the external command has any errors etc.

2. If none of this gives you any new information, you can try as a last
   resort looking at the Tex_ViewLaTeX() function in
   ~/.vim/ftplugin/latex-suite/compiler.vim. This is the function
   invoked when you type \lv.

Bad news: wrong CWD was wrong ..

I looked into the function and put some new debug statements there to be
sure what the cwd is. There was no problem at all.

Good news: 

Problem is fixed. :-) Here a small log of my analysis:

When i opened the file in nautilus (the gnome file explorer) with "GVim
Text Editor", I had _two_ buffers in vim. One with "~/path/file.tex" and
one with "file:///home/me/path/file.tex". Dont know why. 

But starting a file from nautilus with my homebrewn command "gvim", i
had only one buffer, and surprisingly "\lv" works fine.

To reproduce the error, I launched gvim from the shell the same way it
is launched from nautilus:

# gvim -f file:///home/me/path/file.tex

And look, i had two buffers and \lv didnt work. Interestingly, 

# gvim  file:///... (without '-f')

opens two buffers but \lv works. 

Looking into the man-page "-f" means "foreground, do not fork and detach
from the shell vim was started in". Whatever that means.

Testing

# gvim -f path/file.tex

results in one buffer, but \lv doesnt work. So forget the two buffers
and file:// URL and focus on "-f"

So i guess the problem is analyzed and solved, but im not sure whose it
is :-)

Got it. I am in my homefolder, instead of the folder the tex/dvi file
resides in. Now i think that's a problem with my OS/Desktop.

Or should latexsuite use the absolute path !?

Thanks for the support, latexsuite rocks :-)

Sebastian.

Well, latex-suite at least in my case, does not care about the current
directory of vim as long as the DVI file is in the same directory as the
tex file being edited. It also figures out the path using the .latexmain
file if found.. So something like:

    $ cd ~/research/phd/
    $ vim main.tex
        :cd /tmp " from within vim
        \lv      " in normal mode.

works for me. I hope the sequence of actions I'm describing is clear.
