Is it necessary to set defaultFormatter for a specific language?

description

I try oxlint and oxfmt now. I follow the doc to set up the configuration in VS Code.

When I set "editor.defaultFormatter": "oxc.oxc-vscode" and open the context menu to check with the Format document with..., it's still prettier. But when I set it for a specific language, it works. I'm not sure if it's necessary to set defaultFormatter for a specific language.

Following is my .vscode/settings.json

{
  "oxc.fmt.configPath": ".oxfmtrc.json",
  "editor.defaultFormatter": "oxc.oxc-vscode",
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.oxc": "always"
  },
  "oxc.typeAware": true,
  "[javascript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[javascriptreact]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[typescript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[typescriptreact]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[vue]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[json]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[jsonc]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[css]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[scss]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[markdown]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  }
}

hm looks like your node path is not found by VSCode/oxlint anymore. Could you check your Path env and re-add it, if missing?

I fixed my VS Code and the Format document with... is still prettier without the specific language setting.

Thanks for looking into this :)
Will check if I can improve the selectors 🤞

Released a new VSCode Extension version today (1.47.0) could you recheck if you need to still have the language selectors?

I updated and still need to have the language selectors.
