[Vim-latex-devel] bug in launching the viewer on Mac OS X

[William (B.J.) S. O. <aet...@gm...>]

I believe I have run into a bug in the Tex_ViewLaTeX function under Mac
OS X. Each time Tex_ViewLaTeX() runs on a macunix system, it prepends an
additional '-a ' to the s:viewer variable. If Tex_ViewLaTeX is called
multiple times in a given session, (using '\lv', for example) it only
successfully runs the viewer every other time it is called.

This leads to Tex_PrintDebug() output along the lines of:

comp : Tex_ViewLaTeX: execString = open -a /Applications/Skim.app thesis.pdf
comp : Tex_ViewLaTeX: execString = open -a -a /Applications/Skim.app thesis.pdf
comp : Tex_ViewLaTeX: execString = open -a -a -a /Applications/Skim.app thesis.pdf

Attached is a patch I created as a workaround to this problem. The patch
inserts a '-a ' in execString if s:viewer is nonempty, rather than
modifying s:viewer each time Tex_ViewLaTeX() is called. This ensures
that there is only ever a single '-a' in execString, if a viewer program
is specified.

I had this problem with latexSuite20060325, but it looks like it may
still exist in the subversion trunk.
