Autocmd background resets colorscheme to default

[tomvanderlee]

I use vim in a terminal emulator and as suggested in the readme I have this in my vimrc

autocmd ColorScheme janah highlight Normal ctermbg=235
colorscheme janah

One problem though, it sets the background correctly but it resets the colorscheme to the default colorscheme.

If i do :colorscheme janah it works properly though.

Any idea why and how to fix it?

What's the output of :echo colors_name after starting?

Vim or Neovim? I see that you use &t_Co in your vimrc, but Neovim doesn't have these options anymore. Maybe it's throwing an error that gets caught and thus it sets desert instead?

Both in vim and neovim i get

E121: Undefined variable: colors_name
E15: Invalid expression: colors_name

You are talking about this snippet?

try
    if (&t_Co == 256) && match($TERM, "256color") >= 0
        autocmd ColorScheme janah highlight Normal ctermbg=235
        colorscheme janah
    else
        throw "nocolor"
    endif
catch
    colorscheme desert
endtry

I know it executes the if (&t_Co == 256) && match($TERM, "256color") >= 0-block because the background color gets set correctly, but the colorscheme itself is set to default. it is also not falling back to desert, because the output of :colorscheme is default.

it is really weird and even if I do

 autocmd ColorScheme janah highlight Normal ctermbg=235
 colorscheme janah

without the fancy try-catch stuff the colorscheme is still set to default, but the background color is as expected

Actually I think you're hitting one of the many highlighting bugs of Vim. In your case it gets triggered by setting 'background' after the :autocmd.

Doesn't work:

colorscheme janah
autocmd ColorScheme janah highlight Normal ctermbg=235
set background=dark

Does work:

colorscheme janah
set background=dark
autocmd ColorScheme janah highlight Normal ctermbg=235

There's no way I can fix this from the colorscheme itself, but I could add a note to the README. My suggestion it to simply do all the colorscheme stuff after setting options in your vimrc.

That fixed it!

Thanks for helping me and thanks for creating this awesome colorscheme!
