# How to do forward search to PDF file opened with Okular from include files when editing using VIM/GVIM

I'm using vim to edit my tex files and I use latex suite as a plugin to compile my tex sources and view them in using Okular pdf viewer.

Setting the following in Okular settings makes inverse search work perfectly

``````gvim --servername GVIM --remote +%l %f
``````

But having looked on the web and tried different ways to make forward search work within vim with latex suite, forward search is still working only partly for me in vim. I'm only able to do forward search with `\ls` in the main tex file. If I do `\ls` inside an include or input file then Okular would complain that it can't find the particular pdf for that include/input file which is true because only the main tex file has a pdf compiled.

I also tried a custom function which I found from an answer to a similar question here on TeXExchange: http://tex.stackexchange.com/a/2947/2031 but the path passed to Okular with this command is just a concatenation of the paths to both the main pdf and tex files.

Below are my current settings in my .vimrc related to this question:

``````let g:Tex_CompileRule_pdf = 'pdflatex -synctex=1 -src-specials -interaction=nonstopmode \$*'
let g:Tex_ViewRule_pdf = 'okular --unique'
function! SyncTexForward()
let execstr = "silent !okular --unique %:p:r.pdf\#src:".line(".")."%:p &"
exec execstr
endfunction
``````
-

``````function! SyncTexForward()
Many thanks! That worked. Just one thing to note that in order for `Tex_GetMainFileName()` to work properly one should have a `{main tex file name}.latexmain` file in the same directory with their main tex file (as described here vim-latex.sourceforge.net/documentation/latex-suite/…) –  ld_pvl Nov 22 '12 at 21:43
