## README

# Camunda FEEL Builtins

[![CI](https://github.com/camunda/feel-builtins/actions/workflows/CI.yml/badge.svg)](https://github.com/camunda/feel-builtins/actions/workflows/CI.yml)

Collection of builtin Camunda extensions for FEEL (Friendly Enough Expression Language). These builtins get extracted from [camunda-docs](https://github.com/camunda/camunda-docs/tree/main/docs/components/modeler/feel/builtin-functions).

## Installation

Install via npm:

```sh
npm install @camunda/feel-builtins
```

## Usage

This package exports multiple collections of FEEL builtins:

* **`camundaBuiltins`**: Collection of builtins of camunda scala FEEL.
* **`feelBuiltins`**: List of standard FEEL built-in functions (excluding Camunda-specific extensions).
* **`camundaExtensions`**: List of FEEL camunda extensions.
* **`camundaReservedNameBuiltins`**: Functions using reserved keywords in their name and need to be added to the parser context during parsing.

You can feed built-ins as context into your favorite [FEEL editor](#feel-editor) or [validator](#feel-lint).

### Feel Editor

In your [FEEL editor](https://github.com/bpmn-io/feel-editor) you can use these builtins to establish the Camunda context:

```js
import { camundaBuiltins } from '@camunda/feel-builtins';
import FeelEditor from '@bpmn-io/feel-editor';

const editor = new FeelEditor({
  container,
  builtins: camundaBuiltins,
  parserDialect: 'camunda'
});
```

If you only want standard FEEL functions, use `feelBuiltins` instead:

```js
import { feelBuiltins } from '@camunda/feel-builtins';

const editor = new FeelEditor({
  container,
  builtins: feelBuiltins
});
```

### Feel Lint

With [@bpmn-io/feel-lint](https://github.com/bpmn-io/feel-lint) you can also use the builtins to lint expressions in the Camunda world:

```js
import { camundaBuiltins } from '@camunda/feel-builtins';
import { lintExpression } from '@bpmn-io/feel-lint';

lintExpression(expression, {
  builtins: camundaBuiltins,
  parserDialect: 'camunda'
});
```
