cwal.nvim

cwal.nvim is a dynamic Neovim colorscheme that reads your generated cwal palette and applies it across core UI, syntax, Treesitter, diagnostics, completion popups, Bufferline, and Lualine.

For now, only dark mode is supported.

🖼 Preview

✨ Features

• Uses your live cwal colors from colors-nvim.lua
• Automatically reloads highlights when your cwal.ini changes
• Extensive highlight coverage for:
  • Core editor/UI groups
  • Vim syntax groups
  • Treesitter and semantic token groups
  • LSP diagnostics (Diagnostic* + legacy LspDiagnostics* links)
  • Popup/completion UI (Pmenu*, Cmp*, BlinkCmp*)
  • Bufferline (BufferLine*)
  • Lualine theme (theme = "cwal")

📦 Requirements

• Neovim 0.10+
• cwal
• A working cwal setup that generates:
  • ~/.config/cwal/cwal.ini
  • colors-nvim.lua inside your configured out_dir

🔧 Installing cwal

Install from the AUR:

paru -S cwal-git

or

yay -S cwal-git

🎨 Color Source

cwal.nvim reads out_dir from your cwal.ini, then loads:

<out_dir>/colors-nvim.lua

🚀 Installation

lazy.nvim

{
  "nitinbhat972/cwal.nvim",
  priority = 1000,
  config = function()
    vim.cmd.colorscheme("cwal")
  end,
}

vim.pack (Neovim 0.12+)

vim.pack.add({
  { src = "https://github.com/nitinbhat972/cwal.nvim" },
})

vim.cmd.colorscheme("cwal")

⚙️ Usage

Set the colorscheme:

:colorscheme cwal

or in Lua:

vim.cmd.colorscheme("cwal")

🔌 Lualine Integration

require("lualine").setup({
  options = {
    theme = "cwal",
  },
})

The colorscheme defines most highlight groups, ensuring compatibility with the majority of plugins.
Note: Bufferline highlight groups are not refreshed automatically on colorscheme change and may require a Neovim restart.

🔄 How Reload Works

cwal.nvim watches:

~/.config/cwal/cwal.ini

On change, it:

1. Reloads palette values from colors-nvim.lua
2. Reapplies all highlight groups
3. Reloads Lualine (if its theme is set to "cwal")
4. Triggers the CwalReload User event

🔔 Events

You can hook into the reload process using the CwalReload User event. This is useful for refreshing other plugins or custom highlights that depend on the palette.

vim.api.nvim_create_autocmd("User", {
  pattern = "CwalReload",
  callback = function()
    -- Your custom logic here, e.g., refreshing a custom statusline or plugin
    print("Cwal colors have been reloaded!")
  end,
})

🛠 Troubleshooting

Color file not found: .../colors-nvim.lua

• Check out_dir in your cwal.ini
• Confirm <out_dir>/colors-nvim.lua exists

📝 Notes

• No user options are required at the moment.
• The plugin is intentionally palette-driven — regenerate your cwal colors and Neovim follows.
