A language server for unocss

Features

• Simple completion
• Hover
• Loading config from root dir
• Highlight color (use with mrshmllow/document-color.nvim)

Install

npm i unocss-language-server -g

For Nix users:

# Install
nix profile install github:xna00/unocss-language-server

# or just run without installing
nix run github:xna00/unocss-language-server -- --stdio

Usage

nvim-lspconfig server_configuration

require 'lspconfig'.unocss.setup {
  on_attach = on_attach,
  capabilities = capabilities,
  filetypes = { ... },
  root_dir = function(fname)
    return require 'lspconfig.util'.root_pattern(...)(fname)
  end
}

If you are using nvim-cmp, you can add - to trigger_characters.

cmp.setup {
  sources = { { name = 'nvim_lsp', trigger_characters = { '-' } } }
}

Because @unocss/autocomplete suggest less before meeting -.

CoC (coc.nvim)

To use the language server with coc.nvim, add the following to your coc-settings.json. CoC connects to the server over stdio, so make sure to include the --stdio argument.

{
  "languageserver": {
    "unocss": {
      "command": "unocss-language-server",
      "args": [
        "--stdio"
      ],
      "filetypes": [
        "typescriptreact",
        "javascriptreact",
        "vue",
        "svelte"
      ]
    }
  }
}
