lualine.nvim errors when calling `setup` in `init.lua`

[playa4l]

Expected behavior

Lualine is loaded.

Current behavior

Lualine throws an error , doesn't load and the rest of the Neovim files are sourced properly.

Reproducing

1. Make sure you installed luarocks for your distro.

2. Get the first init.lua from my Neovim settings.

3. Open Neovim then run :Rocks! install lualine.nvim | q.

4. Subsitute the last line (require('init')) with require('lualine').setup({}).

5. Reopen Neovim.

6. Open Neovim again.

Additional info

I visited the Lualine GH repo and followed the steps to make an issue, including the part involving making an isolated Neovim settings and, after testing, I reached the conclusion the problem is within rocks.nvim, since the actual setup works as intended in the isolated environment.

Hey :wave:

Thanks for reporting :pray:

Result of my investigation:

This is because lualine uses vim.api.nvim_get_runtime_file instead of package.searchpath to search for its themes, which are in the lua directory. This works if the package is installed with a flat hierarchy (which is how most plugin managers install plugins), but not if it is installed as a luarocks package.

I will look into PRing a fix to lualine.nvim.

In the meantime, there are these workarounds:

• Call lualine.setup() in a plugin script, e.g. ~/.nvim/plugin/lualine.lua
• Use rocks-config.nvim to configure lualine
• Use rocks-git.nvim to install lualine.nvim
