Issue Description

I use CoC a lot, particularly for its LSP offerings. For LaTeX, I make use of coc-texlab, which, among other things, allows me to autoformat latex files through the use of latexindent.

I was working on Overleaf.com, using firenvim, and tried calling the autoformatting like I normally would, but nothing happened.

From here I tried a few things:

• call autoformatting in a more manual way, i.e. :call CocAction("format")
  • it did not work
• tried running the formatting on a normal nvim instance on my terminal on a copy of the latex file i was editing on overleaf
  • it worked as expected
• checked that the correct filetype was being picked up by firenvim
  • it was, as confirmed by correct syntax highlighting
  • for safety, i also used :set filetype=latex
• tried editing a tex file on a different website, my CV here on GitHub
  • autoformatting also failed to do anything here
• tried editing another kind of file on GitHub
  • tried markdown, javascript, python
  • formatting always worked flawlessly, but here I am not using coc-texlab but rather coc-jedi or coc-prettier
• went through the TROUBLESHOOTING.md guide on this repository, to no avail.

So my conclusion is that for some reason, perhaps due to the internal machinations of latexindent, coc-texlab, firenvim, or some combination of these three, autoformatting with latexindent does not work in a firenvim instance, despite working in a normal nvim instance.

I understand this is a very niche issue and you may not have the bandwidth to solve it. If you have any ideas what's up, I'm all ears. If not, I thought I'd signal it here, in case someone else comes across this bug. Fortunately it's quite small and overall I'm very happy with firenvim.

PS: wrote this issue with firenvim ;).

I think the problem probably is that latexindent is not in your $PATH. What happens when running :!which latexindent from firenvim and from the terminal?

[thesofakillers]

Forgot to mention that I also tried that. Running that command gives the same both from firenvim and from the terminal, i.e. I get /Library/TeX/Distributions/.DefaultTeX/Contents/Programs/texbin/latexindent, which seems correct.

Does running :%!latexindent in a buffer containing the latex code you want to indent work when done from firenvim?

[thesofakillers]

Interesting. In my nvim terminal this prints x lines filtered when there is some autoformatting to do, or nothing. In firenvim, I get the following

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LC_ALL = (unset),

This is weird because I definitely have YAML/Tiny.pm installed.
