prettier-plugin-freemarker


A Prettier plugin for formatting FreeMarker template files (.ftl).

Installation

``bash
npm install --save-dev prettier prettier-plugin-freemarker
`

Usage

$3

Once installed, Prettier will automatically detect and use the plugin for .ftl files:

`bash
npx prettier --write "*/.ftl"
`

You can also explicitly specify the plugin:

`bash
npx prettier --plugin prettier-plugin-freemarker --write "*/.ftl"
`

$3

Add the plugin to your Prettier configuration file (.prettierrc, .prettierrc.json, etc.):

`json
{
"plugins": ["prettier-plugin-freemarker"]
}
`

$3

`javascript
const prettier = require("prettier");
const plugin = require("prettier-plugin-freemarker");

const formatted = await prettier.format(code, {
parser: "freemarker",
plugins: [plugin],
});
`

How It Works

This plugin extends Prettier with support for FreeMarker templates by providing:

- Languages: Registers the FreeMarker language with .ftl file extension
- Parsers: Parses FreeMarker template syntax into an AST
- Printers: Converts the AST back to formatted code

Supported File Extensions

- .ftl`
