Tex_GetMainFileName() works incorrectly when first argument is e.g. ':h'

[netvl]

Let ~/Documents/thesis be a directory with a main file, main.tex, and main.tex.latexmain is present in the directory.

:echo Tex_GetMainFileName(':p:h')

Should print ~/Documents/thesis, but it prints ~/Documents/thesis.tex instead. This is caused by this piece of code in Tex_GetMainFileName:

if lheadfile !~ '\.tex$'
    let lheadfile .= '.tex'
endif

This is not a problem per se because LaTeX-Box does not call this function with :h-like argument. But it interferes with vim-latex plugin operations because vim-latex also contains Tex_GetMainFileName function (looks like LaTeX-Box borrowed it from vim-latex), so there is a name clash, and for some reason the function from LaTeX-Box is sometimes invoked regardless of Plugin order in my .vimrc. vim-latex version of this function does not contain the offending lines listed above so it always works correctly.

I guess the function should be renamed to LatexBox_Tex_GetMainFileName or something like this in order to resolve the conflict.

First: With vim-latex, I presume you mean Latex-Suite. LaTeX-Box was not designed to work along other LaTeX-plugins, and so it is not desirable to change the name of the functions.

I'll look into the issue you mention some time later when I have spare time.

It seems the piece of code you refer to was introduced when fixing #48, see here. It seems to me someone did not understand that the latexmain file name should always be on the form <name>.tex.latexmain. Thus I'll remove the mentioned piece of code, which should solve your problem.

@lervag, well, every single function except this one is prefixed with LatexBox_, only this one starts with Tex_. This is somehow inconsistent, isn't it? And BTW this is the only conflicting thing with Latex-Suite, everything else is working fine. (I'm using LaTeX-Box for its great omni-completion features which Latex-Suite does not provide).

[lervag]

@netvl OK, you convince me. I agree it is inconsistent, and if this change makes Latex-Suite work well with LaTeX-Box, there is no reason not to fix this.

@lervag, thanks! And also thank you for the great plugin)

No problem, happy to help :)
