# Transloco MF2

The implementation of the TranslocoTranspiler interface in this project
uses [messageformat V4](https://messageformat.github.io/documents/Project_Overview.html).
Since V4, the library [messageformat](https://github.com/messageformat/messageformat) provides an implementation
of [the Unicode standard MessageFormat 2 (MF2)](https://messageformat.unicode.org/).

The code in this project is inspired by
[the current implementation in the Transloco project](https://github.com/jsverse/transloco/blob/transloco-7.6.1/libs/transloco-messageformat/src/lib/messageformat.transpiler.ts),
which uses [messageformat V3](https://messageformat.github.io/messageformat/api/).

For more details, you can read
[this great article](https://blogs.igalia.com/compilers/2024/05/06/messageformat-2-0-a-new-standard-for-translatable-messages/).

## Installation in your project

Transloco must be installed and configured in your application.

You also must install the latest version of [messageformat](https://www.npmjs.com/package/messageformat).

```
pnpm add @cloarec/transloco-mf2
```

Then in your `main.config.ts` :

```typescript

export const appConfig: ApplicationConfig = {
    providers: [
        //...
        provideTransloco({
            //... your configuration
            // change default transloco interpolation to prevent conflict
            interpolation: ['<<<', '>>>'],
        }),
        provideTranslocoMF2Transpiler({
            // https://messageformat.github.io/variables/messageformat_functions.DraftFunctions.html
            includeDraftFunctions: true
        }),
    ],
};
```
