# Md Prettier

Beautify markdown.

## Code

```space-lua
local prettier = js.import("https://cdn.jsdelivr.net/npm/prettier/standalone/+esm")
local prettierMarkdown = js.import("https://cdn.jsdelivr.net/npm/prettier/plugins/markdown/+esm")

function formatText(text)
  return prettier.format(text, {
    parser = "markdown",
    plugins = { prettierMarkdown },

    printWidth = 160,
    proseWrap = "preserve",

    -- These DO NOT affect markdown tables
    useTabs = true,
    tabWidth = 4,
  })
end

function formatDocument()
  local text = editor.getText()
  local formattedText = formatText(text)
  editor.setText(formattedText)
end

command.define {
  name = "Beautify: markdown",
  run = formatDocument,
}
```

**Important Notes:**

- **Placement:** `prettier-ignore` _must_ be the very first line within the code
  fence. Any leading whitespace will cause it to be ignored.
- **Scope:** `prettier-ignore` applies to the entire code fence it's placed in.
- **Alternative:** If you want to disable formatting for a specific section of
  code _within_ a code fence, you can use `prettier-ignore` on a single line:
