neovim Latex-to-Unicode Support

[xanderdunn]

I have let g:latex_to_unicode_auto = 1 in my ~/.config/nvim/init.vim.

In a julia file, when I type \neq, nothing happens.

When I type \alpha, I get:

So, it sort of worked. The unicode alpha symbol was inserted, but the alpha characters remain and it looks like some unusual character (escape?) sequence <91> was inserted.

Many thanks for this plugin!

@carlobaldassi It looks like the bit about neq can be ignored. It's defined as ne, which works the same as all the other defined symbols:

So, the issue is simply that it looks like the escape sequence to get out of completion mode isn't working in neovim, hence the <91>.

Thanks for the report, I'll have to try out neovim and see what can be done.

I just installed neovim and I can't reproduce the problem, everything works in my setup.
Could you provide more details about your system? In particular, the OS, the neovim version (I just cloned the most recent from github) and possibly a minimal nvim/init.vim for which you see the problem.

Did you maybe try this with vim as well?

@carlobaldassi Thanks for looking at this. I've also installed neovim from HEAD on GitHub. It's version:

NVIM 0.1.0-dev (compiled Nov 29 2015 21:04:24)
Commit: 7d42e9b7e8169da45e32c415babc27b197a26f8a

After doing a binary search commenting out lines in my init.vim, I discovered it was specifically this line and no more or less that caused it:
"inoremap <silent> <c-h> <Esc>:TmuxNavigateLeft<cr>I

Wow! These are commands I use to navigate between tmux panes from within vim from this plugin. Does this make any sense to you?

[carlobaldassi]

Good catch. It doesn't make sense to me but I can reproduce this, even in vim. I'll investigate.

[carlobaldassi]

Ok I found out what happens. In vim, <C-H> in insert mode is the same as backspace \b. The auto-L2U code uses \b (the escape sequence inserts a character and then deletes it), and that's what triggers the problem.
I assume you don't use backspace in your workflow (if you did, it should call your tmux navigation code).
I'm not sure how to get out of this. I'll see if I can come up with some way to avoid using \b.

@carlobaldassi

Very cool, thanks.

[carlobaldassi]

Should be fixed now. I just forgot an option in the feedkeys call to avoid remapping.

[xanderdunn]

I updated my plugin and it works even with my Tmux key mapping. Many thanks!
