More or less I have solved the problem I asked about: the solution is as
follows (from my tex.vim):
---------------------------------------------------------
function! Set_PDF()
let g:Tex_CompileRule_pdf = 'pdflatex --synctex=1
-interaction=nonstopmode -file-line-error-style $*'
let g:Tex_ViewRule_pdf = 'okular --unique 2>/dev/null 1>&2 '
let g:Tex_DefaultTargetFormat = 'pdf'
exec 'TTarget '.g:Tex_DefaultTargetFormat
endfunction
function! Set_LaTeX()
let g:Tex_CompileRule_dvi = 'latex -src-specials
-interaction=nonstopmode -file-line-error-style $*'
let g:Tex_ViewRule_dvi = 'xdvi 2>/dev/null 1>&2 '
let g:Tex_DefaultTargetFormat = 'dvi'
exec 'TTarget '.g:Tex_DefaultTargetFormat
endfunction
noremap <leader>latex :call Set_LaTeX()
noremap <leader>pdf :call Set_PDF()
if getline(1) =~ "PDFLaTeX" | :call Set_PDF() | endif
-------------------------------------------------------------
Now, from within a file I am able to switch pdf/latex compilation and
correct visualization.
The only thing that I can not fix is the following: I would like to have
the file recognized upon opening. For this, if a file is meant to be
pdflatex it has the first line equal to
%PDFLaTeX
so that it should trigger the "if getline..." in tex.vim
The problem is that when I open such file I get the following error:
"file.tex" 194L, 5881C
Error detected while processing function Set_PDF:
line 4:
E492: Not an editor command: TTarget pdf
How do I fix this?
TIA
