Closing latex environments about vim-endwise HOT 9 OPEN

This has been working for me:

  autocmd FileType tex
        \ let b:endwise_addition = '\="\\end" . matchstr(submatch(0), "{.\\{-}}")' |
        \ let b:endwise_words = 'begin' |
        \ let b:endwise_pattern = '\\begin{.\{-}}' |
        \ let b:endwise_syngroups = 'texSection,texBeginEnd,texBeginEndName,texStatement'

Edit: you can do \begin{env*} now too.

So far after some playing I was able to figure out that the following sequence does the job:

let b:endwise_words = '\\begin{\zs[a-zA-Z0-9*]*\ze}' " ignored
let b:endwise_pattern = '\\begin{\zs[a-zA-Z0-9*]*\ze}'
let b:endwise_addition = '\\end{&}'
let b:endwise_syngroups = 'texBeginEndName'

But it doesn't prevent endwise to add the ending even if it already exists. For now I don't know how it works and how it can be fixed.

Nevertheless, this could for better or worse be included in the standard plugin.

Where did texBeginEndName come from? I see texSection (though this might be version dependent).

It's from vim's tex syntax file.
vim 7.3.1287

That's a curious inconsistency with both 7.3.000 and 7.4.000 but doesn't appear to be relevant. b:endwise_words needs to be a comma delimited list of words. You might have better luck if you start by trying to target a few specific environments. I doubt a general solution is possible without tweaking the rest of the implementation.

The example given by @maxfl doesn't seem to work for me. This would be very cool to have working somehow in any case.

from vim-endwise.

I can confirm @maxfl example works and the problem with preventing extra endings exists. There's two factors affecting this.

Firstly, b:endwise_addition is not escaped when endpat is generated so the double-slashes in \\end becomes \end when doing searchpair.

Secondly, in Latex's syntax highlighting, \begin{foo} has two different syntax groups, \begin having texBeginEnd and foo with texBeginEndName. My current method is to introduce a new variable b:endwise_endsyngroups which when defined, overrides b:endwise_syngroups in mysearchpair.

Another minor issue is that the \begin has a lot of environments, so a new tag may match an already existing, but different tag. I believe it is possible to generate the exact end pattern from word when doing searchpos.

Thanks @elliotpatros! That works for me :)
