SomMark-LSP

Language Server Protocol (LSP) implementation for the SomMark markup language.

Features

• Diagnostics: Accurate syntax error reporting with precise ranges.
• Semantic Highlighting: Perfect token-based coloring in any editor that supports LSP Semantic Tokens (VS Code, Neovim, CoC).
• Easy Sharing: Install globally to use across all editors with a single command.

Installation

Go to the SomMark-LSP directory and install the server globally:

npm install -g sommark-lsp

This will register the sommark-lsp command.

Editor Integration

Vim (coc.nvim)

Add the following to your coc-settings.json:

{
  "languageserver": {
    "sommark-lsp": {
      "command": "sommark-lsp",
      "args": ["--stdio"],
      "filetypes": ["sommark", "smark"],
      "rootPatterns": ["package.json", ".git"]
    }
  },
  "semanticTokens.enable": true
}

And add these to your .vimrc:

autocmd BufRead,BufNewFile *.smark set filetype=sommark
hi link CocSemKeyword Keyword
hi link CocSemString String
hi link CocSemVariable Identifier

Neovim

Use nvim-lspconfig or manually:

vim.lsp.start({
  name = 'sommark-lsp',
  cmd = {'sommark-lsp', '--stdio'},
  root_dir = vim.fs.dirname(vim.fs.find({'package.json', '.git'}, { upward = true })[1]),
})

Helix

Add to ~/.config/helix/languages.toml:

[language-server.sommark-lsp]
command = "sommark-lsp"
args = ["--stdio"]

[[language]]
name = "sommark"
scope = "source.sommark"
file-types = ["smark"]
language-servers = [ "sommark-lsp" ]

[!NOTE] Helix support is currently limited; diagnostics and some features work, but full syntax highlighting requires a Tree-sitter grammar (coming soon).

Configuration

You can configure the LSP behavior via smark.config.js in your project root.
