[WIP] coc-ast-grep

fork from a ast-grep-vscode

coc.nvim extension for ast-grep language server

Install

You need to have coc.nvim installed for this extension to work.

e.g. vim-plug:

Plug 'yaegassy/coc-ast-grep', {'do': 'yarn install --frozen-lockfile'}

Usage

The ast-grep language server requires sgconfig.yml in the project root to work properly.

• See: https://ast-grep.github.io/guide/rule-config.html

!!Known Issues!!

The language client will crash if sgconfig.yml is not in the project root or if the rules are not properly configured.

I think it needs to be adjusted either on the ast-grep language server (sg lsp) side or on the coc.nvim side.

!!Note!!

Currently the extension is only enabled in typescript files.

{
  // ...snip
  "activationEvents": [
    "onLanguage:typescript"
  ],
  // ...snip
}

Configuration options

• astGrep.enable: Enable coc-ast-grep extension, default: true
• astGrep.serverPath: Specify the language server binary path. If the binary is not found, use the binary included in the extension, default: sg
• astGrep.configPath: Customize ast-grep config file path relative.

To register a ast-grep language server without coc-extension

Add the following settings to coc-settings.json.

{
  "languageserver": {
    "ast-grep": {
      "command": "sg",
      "args": ["lsp"],
      "filetypes": ["typescript"],
      "rootPatterns": [
        "sgconfig.yml"
      ]
    }
  }
}
