Use base16-shell + base16-vim to set colorscheme

[neverfox]

Expected behavior, english is recommend

Changing terminal colors with base16-shell and base16-vim plugin installed should change spacevim colorsheme.

The reproduce ways from Vim starting (Required!)

1. Follow these instructions except add chriskempson/base16-vim the spacevim way. i.e. g:spacevim_custom_plugins = [['chriskempson/base16-vim']]
2. Start spacevim (plugin will install)
3. Colorscheme is still default gruvbox and doesn't match shell colors
4. Try again with colorscheme layer loaded. No change.

Now, I didn't expect this to work because spacevim doesn't (I believe?) use .vimrc or if it does, it overrides the colorscheme by default. So really I'm asking if there's a way to configure spacevim to use the .vimrc_background file that base16-shell produces dynamically to set the colorscheme using those provided by base16-vim.

please read :h g:spacevim_colorscheme

I did. I know I can hardcode the value (say, base16-nord) and it works (except for the powerline bar), but what I'm asking is if there's a way to set the value dynamically. If this were not spacevim, I would do the following:

1. Run a base16-shell command in terminal, e.g base16_darktooth. base16-shell produces the file ~/.vimrc_background:

   if !exists('g:colors_name') || g:colors_name != 'base16-darktooth'
   colorscheme base16-darktooth
   endif

2. Add the following to ~/.vimrc:

   if filereadable(expand("~/.vimrc_background"))
   let base16colorspace=256
   source ~/.vimrc_background
   endif

3. Profit. Shell and vim have matched colorscheme, based on whatever base16-shell theme was selected.

I'm wondering if there is a way to leverage the .vimrc_background file to set g:spacevim_colorscheme. I was hoping against hope that it would just work but that was based on a bad assumption that Spacevim might respect a .vimrc file and furthermore set g:spacevim_colorscheme based on mere colorscheme.

The solution might be to use the fact that base16-shell also sets the environment variable BASE16_THEME. Is there a way to reference that when setting g:spacevim_colorscheme?

[neverfox]

Figured it out.

let g:spacevim_colorscheme = 'base16-' . $BASE16_THEME

[wsdjeg]

nice！

How would one do this in the new .toml based settings file?
