How to test a plugin during development?

[PEZ]

Hi! Thanks for this Extension!

I am creating a Prettier plugin (for Clojure). I can run prettier just fine from the command line, and it formats Clojure files as well as clojure fenced code blocks in Markdown. However, I fail to tell VS Code that the Prettier Code Formatter extension now can format Clojure files. I've read these:

• Plugin support? #395
• Plugin Support #899

Frome those I seem to conclude that if I npm install prettier and my plugin, then this extension should pick it up. I still get this, though:

I don't know what to try now. Any ideas?

Have you tried to set the editor.defaultFormatter option?

settings.json:

{
  "editor.defaultFormatter": "esbenp.prettier-vscode"
}

You can also wrap it for a specific language:

{
  "[dockercompose]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  },
}

But you have to npm add -D prettier in your project (make sure to use the correct version here, as version 3 is not compatible with some plugins) and use a local .prettierrc.json.

Also, npm link in your local package and npm link clojure-prettier-plugin (replace the name of your local package) in your example project you want to use to test your plugin.

In your .prettierrc.json you need to add your plugin as { "plugins": ["clojure-prettier-plugin"] }.
