joom / latex-unicoder.vim Goto Github PK

Strings that are in between two matches convert to the shorter match, but delete the extra characters. For example:
\p \pi \pit \pitchfork becomes π π ⋔ (the \p is deleted)

Is it possible to invert the operation?
I would like to be able to select symbols and
convert them back into commands.

While \alpba \beta converts to α β, it's not the case that \alpha\beta converts to αβ.

Is there a way to fix this?

(1) While \alpha correctly converts to α, it's not the case that $\alpha$ converts to α nor even $α$.

(2) It would also be cool to go in the reverse direction too: that is to go from α to $\alpha$in the code (giving you a way to preview latex files within vim by going back and forth between $\alpha$ and α).

Overall fixing (1) would be much more useful (at least to me) than (2) :)

When I add latex-unicoder to my init.vim I lost my desired behaviour for <C-l> shortcut. is there a way to avoid this?

I try adding:

" ========= latex unicoder ==========
let g:unicoder_cancel_normal = 1
let g:unicoder_cancel_insert = 1
let g:unicoder_cancel_visual = 1
nnoremap <F3> :call unicoder#start(0)<CR>
inoremap <F3> <Esc>:call unicoder#start(1)<CR>
vnoremap <F3> :<C-u>call unicoder#selection()<CR>

but not takes effect.

It would be great to be able to visually select an already written latex-symbol in the file and use ctrl-L to substitute the selection with the unicode symbol, instead of typing it out into the prompt again.

It would be nice if there was a variable one could set to disable either the insert or normal mode mapping.

For example:

\dot{a} \dota a\dot
\hat{o} \hato o\hat

converts into

ẋ{𝑎} ẋ𝑎 𝑎ẋ
x̂{𝑜} x̂𝑜 𝑜x̂

In Unicode diacritics are combining characters but in s:presymbols they are listed as already combined with x.

Whenever I use latex-unicoder to input a symbol, the cursor always ends up moving to the next line after the symbol gets inputted. Which is to say that this happens:

1. I press C-l
2. I type something, e.g. \lambda
3. I press
4. λ gets inserted at the cursor
5. The cursor moves down to the first character of the next line.

The desired behaviour would of course be that the cursor just moves so that it's immediately after the symbol.

Pull request incoming to fix this issue. Involves mapping commands not to <C-l> directly but to <Plug>Unicoder, and then only setting <C-l> to <Plug>Unicoder if g:unicoder_no_map isn't set. The the user's .vimrc can then look like

" Unicoder stop clobbering my C-l
let g:unicoder_no_map = 1
map <C-g> <Plug>Unicoder

When adding symbols in normal mode, everything is perfect. But in edit mode an extra space is added before the inserted character.

The documentation says that the map would also work in insert mode, but it does not. Note that :map only works in normal, visual, select and operator-pending modes. One should either change the documentation or the :map call.
