# decodal-codemirror

CodeMirror 6 language support for Decodal.

This package provides the Lezer parser metadata, highlighting tags, indentation rules, and block folding used by the Decodal Web playground.
It does not include the Decodal runtime or WebAssembly evaluator.
Use `decodal-wasm` when you want to evaluate Decodal in a browser.

## Install

```sh
npm install decodal-codemirror
```

JSR:

```sh
deno add jsr:@hare/decodal-codemirror
```

## Usage

```js
import { basicSetup } from 'codemirror';
import { EditorView } from '@codemirror/view';
import { decodal } from 'decodal-codemirror';

new EditorView({
  doc: 'Server = { port = Int default 8080; };',
  extensions: [
    basicSetup,
    decodal(),
  ],
  parent: document.querySelector('#editor'),
});
```

## Exports

```js
import {
  decodal,
  decodalLanguage,
  decodalHighlightStyle,
} from 'decodal-codemirror';
```

`decodal()` accepts a small options object:

```js
decodal({ highlight: false })
```

Use this when you want the language support without the bundled highlight style.
