coc-tsdetect

vim-tsdetect

vim-tsdetect/coc-tsdetect provides vim/neovim and coc.nvim extension to initialize workspace automatically for coc-tsserver and coc-deno.

Installation

Run :CocInstall coc-tsdetect in vim/neovim or install vim-tsdetect with your favorite plugin manager and build with pnpm install && pnpm run build. It is enough to install one of them.

How does this detect TS environments?

Checking following in order.

• If buffer name starts with deno:/ -> deno
• If buffer name ends with .js, .ts, .tsx -> check following in order
  a. Shebang is present and including node -> node
  b. Shebang is present and including deno -> deno
  c. node_modules/ directory is found in ancestors of (following) -> node
  - If buffer name is not empty, search from that path.
  - Otherwise, search from current working directory.
  d. Otherwise. -> deno
• -> Check following in order
  a. Shebang is present and including node -> node
  b. Shebang is present and including deno -> deno
• Otherwise, nothing is detected.

When does this try to detect?

This tries to detect when following events occurred.

• FileType javascript,javascriptreact,typescript,typescript.tsx,typescriptreact
• BufEnter,BufNewFile,BufWritePost *

Options

Please configure following if necessary by :CocConfig.

tsdetect.mode

Set this "manual" to disable auto initialization. Variable b:tsdetect_is_node remains available.

Values: "auto" | "manual"

Default:

{
  "tsdetect.mode": "auto"
}

tsdetect.doNotCreateOnNode

By default, in Node.js environment, tsdetect does not create a workspace configuration (.vim/coc-settings.json). Set this false to create configuration file whether the configuration exists.

Values: boolean

Default:

{
  "tsdetect.doNotCreateOnNode": true
}

tsdetect.nodeOverride

Workspace configuration to be set in Node.js environment. If you want to extend original configuration, you need to include default ones. Not recommended to touch deno.enable and tsserver.enable.

Values: object

Default:

{
  "tsdetect.nodeOverride": {
    "deno.lint": false,
    "coc.source.file.trimSameExts": [
      ".js",
      ".ts"
    ],
    "prettier.disableLanguages": []
  }
}

tsdetect.denoOverride

Workspace configuration to be set in Deno environment. If you want to extend original configuration, you need to include default ones. Not recommended not to touch deno.enable and tsserver.enable.

Values: object

Default:

{
  "tsdetect.denoOverride": {
    "deno.lint": true,
    "coc.source.file.trimSameExts": [],
    "prettier.disableLanguages": [
      "javascript",
      "javascriptreact",
      "typescript",
      "typescriptreact"
    ]
  }
}

Events

tsdetect#detect

Fired when the tsdetect detects TypeScript environment in the flow shown in above.

tsdetect#detect#node

Fired when tsdetect#detect is fired and environment was detected as node.

tsdetect#detect#deno

Fired when tsdetect#detect is fired and environment was detected as deno.

tsdetect#coc#auto#switch#node#after

Fired after the automatic switch to node triggered and finished.

tsdetect#coc#auto#switch#deno#after

Fired after the automatic switch to deno triggered and finished.

Variables

b:tsdetect_is_node

Set when tsdetect#detect is fired.

Limitations

• Not recommended to include deno.enable and tsserver.enable settings in user configuration (~/.vim/coc-settings.json that can be opened by :CocConfig).
• To prevent .vim/ directory being committed by VCS, you can globally ignore .vim/, or ignore one by one using git update-index --skip-worktree .vim for git projects.

Example Configurations

Example for deno.cache on save if deno environment is detected:

function! s:my_coc_tsdetect_buf_write_post() abort
  if !get(g:, 'coc_enabled', 0)
    return
  endif
  if exists('b:tsdetect_is_node') && !b:tsdetect_is_node
    CocCommand deno.cache
  endif
endfunction

augroup my-coc-tsdetect
  autocmd!
  autocmd BufWritePost * call <SID>my_coc_tsdetect_buf_write_post()
augroup END
