Vim script to compile TeX source and launch PDF only if no errors
- by Jeet
Hi,
I am switching to using Vim for for my LaTeX editing environment. I would like to be able to tex the source file from within Vim, and launch an external viewing if the compile was successful.
I know about the Vim-Latex suite, but, if possible, would prefer to avoid using it: it is pretty heavy-weight, hijacks a lot of my keys, and clutters up my vimruntime with a lot of files.
Here is what I have now:
if exists('b:tex_build_mapped')
finish
endif
" use maparg or mapcheck to see if key is free
command! -buffer -nargs=* BuildTex call BuildTex(0, <f-args>)
command! -buffer -nargs=* BuildAndViewTex call BuildTex(1, <f-args>)
noremap <buffer> <silent> <F9> <Esc>:call BuildTex(0)<CR>
noremap <buffer> <silent> <S-F9> <Esc>:call BuildTex(1)<CR>
let b:tex_build_mapped = 1
if exists('g:tex_build_loaded')
finish
endif
let g:tex_build_loaded = 1
function! BuildTex(view_results, ...)
write
if filereadable("Makefile")
" If Makefile is available in current working directory, run 'make' with arguments
echo "(using Makefile)"
let l:cmd = "!make ".join(a:000, ' ')
echo l:cmd
execute l:cmd
if a:view_results && v:shell_error == 0
call ViewTexResults()
endif
else
let b:tex_flavor = 'pdflatex'
compiler tex
make %
if a:view_results && v:shell_error == 0
call ViewTexResults()
endif
endif
endfunction
function! ViewTexResults(...)
if a:0 == 0
let l:target = expand("%:p:r") . ".pdf"
else
let l:target = a:1
endif
if has('mac')
execute "! open -a Preview ".l:target
endif
endfunction
The problem is that v:shell_error is not set, even if there are compile errors. Any suggestions or insight on how to detect whether a compile was successful or not would be greatly appreciated! Thanks!
