Lua error when using configuration options

[dswij]

On init.vim after installing the plugin:

lua << EOF
require('github-theme').setup({
  themeStyle = "dimmed",
})
EOF

returns an error

E5108: Error executing lua ...im/plugged/github-nvim-theme/lua/github-theme/config.lua:33: attempt to
concatenate global 'vim' (a table value)

Using a minimal neovim config also returns a similar error.

---

For the context, this works fine

lua << EOF
require('github-theme').setup({})
EOF

Are you using nvim >= 0.5?

[dswij]

Yes, using neovim 0.5

[ful1e5]

Can you able to share the nvim config?

[dswij]

Here is the minimal nvim config:

call plug#begin('~/.vim/plugged')
Plug 'projekt0n/github-nvim-theme'
call plug#end()

lua << EOF
require('github-theme').setup({
  themeStyle = 'dimmed'
})
EOF

running nvim -v returns:

I tried your config with nvim-nightly. It's working fine. I tweaked the way to assign global variables on my fork. Give it a try.

call plug#begin('~/.vim/plugged')
Plug 'ful1e5/github-nvim-theme', { 'branch': 'refactor/config.lua' }
call plug#end()

lua << EOF
require('github-theme').setup({
  themeStyle = 'dimmed'
})
EOF

lt changes the theme without error now, but I noticed it overwrites some configs that are declared before it.

That configs are related to github-nvim-theme?

[ful1e5]

I pushed 9fe4e90 on ful1e5/github-nvim-theme . give it try.

[dswij]

Sorry, just had time to look into this again.

I pushed 9fe4e90 on ful1e5/github-nvim-theme . give it try.

This seems to work perfectly fine now! Thanks for this! 🎉
