How to setup Vim-Latex to run only 1 instance of SumatraPDF?

Question

I'm trying to setup vim-latex plugin to do default compile and view using PDF, with SumatraPDF as the default reader. Here's the configuration I made in .vimrc:

let g:tex_flavor='latex'
let g:Tex_DefaultTargetFormat = 'pdf'
let g:Tex_CompileRule_pdf = 'pdflatex -synctex=1 -interaction=nonstopmode $*'
let g:Tex_ViewRule_pdf = 'SumatraPDF'

I've set the PATH variable to points to SumatraPDF installation directory. At this point, \ll and \lv worked perfectly. The only thing that bugged me is that everytime I do \lv, vim-latex automatically open a new instance of SumatraPDF. I use other editor like TexStudio or TeXnicCenter with no problem (view PDF only open one instance). What am I doing wrong? Is there something I have to add in the .vimrc?

I've search everywhere with no result, but if I'm wrong, please just point me to the link.

Answer 1

SumatraPDF can be called with commandline options, see help manual. The option

-reuse-instance

will do the trick

The final modification that made it works is this:

let g:Tex_ViewRule_pdf = 'SumatraPDF -reuse-instance'
