@zhimsel sorry not giving a feedback before.

I've tested over here in a clean environment, and I was not able to reproduce the behavior you described. I mean, I've tested with onlypython-mode andvim-colorschemes plugins and the highlight worked as expected.

Are you sure that there isn't any other plugins/configs interacting in your environment? Which theme are you using? solarized-dark?

It's quite possible. I can do some reductive testing to see if any other plugins are interfering when I get the time. I'll report back here once I've had the chance.

Which theme are you using? solarized-dark?

Yes, solarized-dark.

Thanks@zhimsel !
I'm using a docker-environment to test python-mode. You can give it a try to start from a cleaner env without messing up with your own.
You can find more info about it here:

@diraol I was able to do some more verification of this issue.

Using the following vimrc with neovim0.3.4:

source~/.vim/vim-plug/plug.vim" managed externallycallplug#begin('~/.vim/plugins')  Plug'altercation/vim-colors-solarized'  Plug'~/dev/python-mode',callplug#end()" Set color schemesilent!colorscheme solarizedsetcursorline" Highlight current linesyntaxenable" Enable syntax highlighting" show highlight group for what's under the cursormap<F10>:echo "hi<" . synIDattr(synID(line("."),col("."),1),"name") . '> trans<'\ . synIDattr(synID(line("."),col("."),0),"name") . "> lo<"\ . synIDattr(synIDtrans(synID(line("."),col("."),1)),"name") . ">"<CR>

I confirmed that the. is de-highlighted in the current line withcursorline set. I also tested theflazz/vim-colorscheme version of solarized.

The main reason for this PR was not for a specific issue (my highlighting issue was just a symptom). I submitted this PR because I noticed that thepythonDot highlight group seemed entirely pointless. All it does is drop the highlighting for any. characters toNormal. This doesn't seem to be expected or desired behavior (the. should match the surrounding highlight).

Hum... got it!

Well, I could not reproduce it, not even with your suggestion under a clean env (dockerized).

But the proposed changes seems to be reasonable after all (now that you explained the reason behind it).
So I'll merge and if someone faces issues with it, a new issue can be opened, and we can discuss it better. =) Thanks for the contribution!

No problem! Thanks for merging!
