[Vim-latex-devel] View document in another directory

[Luc H. <her...@fr...>]

Hello,

I'm trying to configure g:Tex_ViewRule_html.
The situation is that into the current directory I have a file foo.tex
and that I use TeX4HT to generate several HTML pages into
the subdirectory ./html/

My first attempt (Win32-vim + cygwin on Windows XP) was to define this
option to: 'cygstart html/'
Unfortunatelly, LaTeXSuite inserts a space just after
g:Tex_ViewRule_html, and thus tries to execute:
    :!start cygstart html/ "foo.html"
(It would have been the same with iexplorer)

Then, I read the man page of cygstart and found out about the =AB-d=BB
option. Unfortunatelly
    $>cygstart -d html foo.html
result in IE trying to open http://html/foo.html. Definitivelly not what
I expected.

Playing with cygstart, I found out that =AB$PWD/html=BB was the argument =
I
was looking for.
Unfortunatelly, while
    :!cygstart $PWD/html/ "foo.html"
works very well,
    :!start cygstart $PWD/html/ "foo.html"
does not. :(


Does anybody know a way to configure g:Tex_ViewRule_html to open the
file ./html/foo.html ?


BTW, I have a request: I'd like an option to disable the default opening
of the preview windows as the quickfix windows is enough for me 99% of
the time.

Okay, this seems like a reasonable thing to want latex-suite to do by
default. I just looked at compiler.vim and it turns out that I use
something like:

    :let execString =3D '!start '.s:viewer.' "'.mainfname.'.'.s:target.'"'
    :exec execString

(here s:viewer =3D Tex_ViewRule_html and s:target =3D 'html')

But I think it would have been better to use the strategy for
Tex_CompileRule_dvi. Basically something like:

    :let _mp =3D &mp
    :let &mp =3D Tex_ViewRule_dvi
    :exec 'make '.mainfname


This way you could have set Tex_ViewRule_html to something like

    :let Tex_ViewRule_html =3D '!start cygstart html/$*.html'

and have things work OOTB.

Maybe have a seperate setting in addition to Tex_ViewRule_html? Something
like Tex_ViewRuleComplete_html which if exists takes precedence over
Tex_ViewRule_html?

As a hack in the while it takes me to modify latex-suite, why don't you
make a little scriptlet which calls cygstart the way you want it to?
It would be a solution for the time being... Something like

#!/usr/bin/bash

cygstart $PWD/html/$*


and then point Tex_ViewRule_html to it...

This should also be an easy thing to modify. I'll put it on the TODO.

That's neat. But a bit problematic.
While this works perfectly with cygstart (because this program forks),
it can not be used with start (execution error) which would be required
with programs that do not fork like AcroRd32 -- I've just made some
experiments.

It seems we will need our own make-like command. Its only work beeing to
substitute $* by the name of the result of the compilation.
In the long run, it can even be extended to support custom formats like
%pwd, %line, %col, ...

Having both approaches to maintain may require more work than necessary.
However, it present the avantage to be more easy to upgrade LaTeXSuite
for end-users.

Moreover, I do not think the complete rule must unhide details like how
the viewer is launched into the background

Indeed. Thanks! (I should have though of it ... a few hours ago I wrote
a wrapper for gvim in order to add "--servername=LATEX" when gvim is
launched with (La)TeX files as parameters.)

Thanks.

Actually you can make it work with !start too. Here's a little demo:

Open vim (not necessarily with latex-suite activated) and do:

let &mp = 'start gvim $*'
silent! make! %

you will need gvim.exe to be in your windows $PATH of course. You should
see another instance of gvim startup and attempt to reread the file....

The silent! is necessary because vim tries to redirect the output of
"!start gvim file" to some temp file and then parse it for errors.
Without the "silent!" it gives an error that the temp file cannot be
opened.

I got carried away and have already implemented this in CVS.

As of right now, I have made it substitute the substring
'{v:servername}' in &mp with v:servername. We could extend it to
something like:

    :function! Eval(expr)
    :    exec 'return '.a:expr
    :endfunction
    :let mp = substitute(&mp, '{\(.\{-}\)}', '\=Eval(submatch(1))', 'g')

This is also done in CVS. Should be uploading shortly.

I though of this solution, but it does not indicate us if the file is
not found, and neither v:shell_error nor :copen are of any help [1]. And
even more important:
    let &makeprg=3D'AcroRd32 $*.pdf'  =20
    silent make foo
works, but=20
    let &makeprg=3D'start AcroRd32 $*.pdf'  =20
    silent make foo
does not.

AcroRd32 seems to receive an incorrect filename in the latter case.


[1] This issue is raised by:
    :let &mp=3D'start! cygstart incorrectpath/$*.html'
    :silent! make foo
    And by extension, if the file to view has not been generated yet,
    \lv would not even tell us there is nothing to view.
    Without =ABstart=BB, the error can be retrieved with :copen

Yes. You're right... I have followed your previous idea of just creating
an imitation of vim's native :make utility. For now, we just substitute
$* with the main file name, but in the future it could be as general
purpose as vim's own.

Hi.

Thanks! So far it works fine.

BTW, I'm testing the files on the CVS (v1.69 IIRC).
I have not set Tex_ViewRule_html, but Tex_ViewRuleComplete_html.
And =AB:TTarget html=BB gives me the following error:
    =ABNo View rule defined for target html
     Please specify a rule in texrc.vim
         :help Tex_CompileRule_format
     for more information.=BB

Where I see the following problems:
- I think we should not get any error message in this case
- the file to modify is not texrc.vim but texrc
- as the help for Tex_CompileRule_format does not say that a view rule
  must be specified, shouldn't the error message point to
  Tex_ViewRule_format ?

Actually, there is one problem line 239 of compiler.vim.
On Windows, the extension is no more used while it is required --
AcroRd32 complains now.
    
The line 
    :let execString = 'start '.s:viewer.' "$*.'.s:target.'"'
seems to fix the problem


Regarding the log file, vim should not complain when the file has
changed. In order to fix this, I've added the following hack into one
tex-ftplugin:
    augroup autoreadLog
      au!
      au BufReadPost *.log :setlocal autoread |:setlocal nomodifiable
    aug END
but I guess there is a simplier and less invasive solution.
