Issues with vim-airline

[flyingfisch]

It looks like maybe nyaovim doesn't know what to do with background colors or something? This is what my editor looks like in nyaovim:

and in terminal:

I've had a similar issue with airline a couple weeks ago, the solution was to update airline and add the new airline-theme repository.

[flyingfisch]

I'll try that when I get home, thanks :)

Installed those, still having issues. Here is my init.vim: https://github.com/flyingfisch/dotfiles/blob/master/nvim/init.vim

Sorry for late response. I tried this.

Just after installing vim-airline, it worked.

Then I installed vim-airline-theme. I'm using lucius color scheme. So I think lucius theme was detected by vim-airline-theme. After restarting NyaoVim, this issue was reproduced.

But when I specified :AirlineTheme base16_asches, it worked. So I think there is some color-specific problem.

We need to investigate further.

[rhysd]

Some themes work but some other themes don't work.

[flyingfisch]

I'm using gruvbox, in case that helps.

vim-airline theme for gruvbox does not exist yet. What vim-airline theme are you using? (:AirlineTheme tells you that.)

[flyingfisch]

It says gruvbox...

[flyingfisch]

Ah, ok. Gruvbox has a bundled airline theme: https://github.com/morhetz/gruvbox#airline-theme

[rhysd]

Oh, I see.

[rhysd]

Note: it seems to fail to specify background color at status line at some colors

[flyingfisch]

OK, just got it working. You have to make sure true color mode is enabled in your init.vim. Maybe true color mode should be enabled by default in nyaovim?

[flyingfisch]

Also, on a side note, how do I install the newest version of nyaovim? I have tried npm install nyaovim but I still have the hollow cursor instead of the new inverted one.

[flyingfisch]

Just realized I forgot the -g flag. I've got the latest version now.

[rhysd]

I looked into more.

Here, the NORMAL is a text in status line with 'lucius' theme with vim-airline. Neovim sends 'change fg/bg color' event and then sends 'render text' event. As described in above log, the 'change fg/bg color' event indicates #d7d7d7 as foreground color and #303030 as background color. Neovim looks sending wrong fg/bg colors for status line.

This could be related to this: https://github.com/vim-airline/vim-airline/issues/1244

I believe that's an issue with airline and any of the latest vim builds (neovim, vim)

[rhysd]

Thank you for the information.

There is one more color-related issue in NyaoVim: #71

It seems that Neovim lacks some color names: Issue. When the color is specified by the lacked color names, it may not reflect to UI.

[flyingfisch]

Wow, I didn't realize I forgot to reply to this issue. I fixed it, for me at least, by adding the following to my init.vim:

let $NVIM_TUI_ENABLE_TRUE_COLOR=1

Really sorry for not updating the thread, I got busy with other things and completely forgot. @rhysd should I close this?

[coddingtonbear]

I, too, encountered this problem and solved it by adding --

set termguicolors

to my ~/.config/nvim/init.vim.

Also note that if you're seeing > rather than ▶, you're probably missing this setting there, too:

let g:airline_powerline_fonts = 1

g:airline_powerline_fonts is what tells Airline to swap the > symbols with ▶ (among other symbols); if you're using a Powerline-compatible font, the ▶ symbols are prettier.
