Setup text argument in user-defined command about vimtex

[lervag]

Hi!

I have a custom \beforetext command that adds text on the left side of an equation. Following #2755, I'd like to know how to setup a local syntax to tell vimtex that what's inside is text. I looked up the commit you made for witharrows and could easily reproduce it, but my command is not attached to any package. Would you be able to point me in the right direction to do that?

  syntax match texMathCmdText "\\beforetext\>"
        \ contained skipwhite nextgroup=texMathTextArg

I believe you can solve this with the g:vimtex_syntax_custom_cmds option. Specify it wherever you specify your other VimTeX options. Something like this:

let g:vimtex_syntax_custom_cmds = [
      \ {'name': 'beforetext', 'mathmode': v:true,
      \  'nextgroup': 'texMathTextArg'},
      \]

As always, thank you for this fantastic plugin and your maintenance of it :-).

Thanks for the kind words! <3

Thank you! I must've missed it, I just started using the useful concealing tools and changed the highlighting groups, but didn't stumble on that.

I'll be the first to admit it's easy to miss things when the documentation has reached 7000 lines of text... in any case, no problem!
