Markdown parser not found using the web-based editor

[mathieu1]

Summary

Markdown parser is not found when using the web-based editor.

Github Repository to Reproduce Issue

This repository

Steps To Reproduce:

1. Open the VS Code web-based editor on this repo
2. Make sure the Prettier extension is installed and enabled
3. Open README.md for editing
4. Remove the second line (between header and first paragraph)
5. Save

Expected result

Format-on-save is supposed to happen, re-introducing the blank line between the header and the text

Actual result

Nothing happens.

Additional information

Format-on-save works for *.js and *.json files at least: after modifying e.g. .eslint.js and saving, format-on-save works correctly.

I'm running into this issue as well for markdown and JSON files. JS files format as expected.

Yep, seeing this as well when trying to edit and tweak Markdown files in various PRs. Would be great to see this fixed!

It is quite weird, this one. I even defined the override to tell prettier which parser to use, but it still gives the same error.

My .prettierrc:

{
  "printWidth": 80,
  "proseWrap": "preserve",
  "endOfLine": "lf",
  "tabWidth": 4,
  "overrides": [
    {
      "files": "*.md",
      "options": {
        "parser": "markdown",
        "printWidth": 80,
        "proseWrap": "always"
      }
    }
  ]
}

Still very much a problem last time I checked.

Same thing, with vscode 1.78. and prettier v9.12.0 Prettier stopped formating

Same here using Turborepo with Svelte and Astro.

prettierrc

// eslint-disable-next-line unicorn/prefer-module, no-undef
module.exports = {
  semi: false,
  proseWrap: "always",
  printWidth: 120,
  pluginSearchDirs: ["."],
  overrides: [
    {
      files: "*.md",
      options: {
        printWidth: 90,
      },
    },
    {
      files: "*.svelte",
      options: {
        parser: "svelte",
      },
      plugins: ["prettier-plugin-svelte", "prettier-plugin-tailwindcss"],
      svelteStrictMode: true,
    },
    {
      files: "*.astro",
      options: {
        parser: "astro",
      },
      plugins: ["prettier-plugin-astro", "prettier-plugin-tailwindcss"],
    },
  ],
};

Still the same error! Seems It was closed because no one was handling it.

[karlhorky]

@ntotten can you reopen this issue and prevent it from being auto-closed? It's still relevant.

Or @mathieu1 could create a new issue...
