Bug 72837 – vim7 and latexsuite raises an error when opening a tex file

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Tom Martin (RETIRED) 2004-11-29 10:52:52 UTC]

On opening a tex file, I get:

Error detected while processing /usr/share/vim/vimfiles/ftplugin/latex-suite/mathmacros.vim:
line  322:
E15: Invalid expression: <plug>\equiv

the file is still opened though, and all features I use actually work. The Tex-Math is loaded up and is usable. I haven't opened up mathmacros.vim and figured out which function/macro/whatever the error occurs in though... I'm kinda rushed for time.

worksforme... So... Could you try vim -i NONE -u NONE and see what happens?

[Comment 2 Tom Martin (RETIRED) 2004-11-30 09:02:09 UTC]

Okay, this is strange:
vim -i NONE -u NONE: no error
vim: no error
gvim -i NONE -u NONE: no error
gvim: error

Ciaran, my .vimrc is near identical to yours, for your information. I can drop you a diff if you like.

[Comment 3 Ciaran McCreesh 2004-11-30 09:06:59 UTC]

Hm, could you just attach the whole vimrc please? I'll try the "remove bits until it works" approach. Or you could do that if you prefer :)

22:38 < p0g> ciaranm: gentoo bug #72837 is a vim problem
22:39 < ciaranm> p0g: you managed to figure it out?
22:42 < p0g> ciaranm: yeah
22:44 < p0g> ciaranm: in version7.txt is the following line:
22:44 < p0g> Skip over the expression in `=expr` when looking for comments, |, % and #.
22:44 < p0g> that happens in separate_nextcmd in ex_cmds.c
22:45 < p0g> but it always tries to skip that
22:45 < p0g> even if the command does not take a backtick expression as an argument
22:45 < p0g> the problem with vim-latex is that it defines a menu with `= in it
22:47 < ciaranm> ok, i see it
22:47 < ciaranm> hrm
22:47 < ciaranm> could just shove a backslash in vim-latex i 'spose

The function in question is vim7/src/ex_docmd.c:separate_nextcmd, in particular this bit:

#ifdef FEAT_EVAL
	/* Skip over `=expr` when wildcards are expanded. */
	else if (p[0] == '`' && p[1] == '=')
	{
	    p += 2;
	    (void)skip_expr(&p);
	}
#endif

So, it's whether this is a vim issue or a vim-latex issue...

I just tested this again, and the problem does not occur with
app-editors/vim-7.0_alpha20050622. Do we just remove the block in its entirety?
I have not checked with previous versions if it still occurs, but I would assume
people who have unmasked vim7 are staying up to date with the latest.

[Comment 7 Ciaran McCreesh 2005-08-05 13:30:46 UTC]

Block removed.
