# Optional Chaining Support for Acorn

[![NPM version](https://img.shields.io/npm/v/acorn-optional-chaining.svg)](https://www.npmjs.org/package/acorn-optional-chaining)

This is a plugin for [Acorn](https://github.com/acornjs/acorn) - a tiny, fast JavaScript parser, written completely in JavaScript.

## Purpose of this fork

This fork exists to enable compatibility with rollup 2.x.  This will be deprecated and archived once
compatibility is merged [upstream](https://github.com/rockon999/acorn-optional-chaining).

## Usage

This module provides a plugin which extends the Acorn `Parser` class to handle optional chaining:

```javascript
import * as acorn from 'acorn';
import optionalChaining from 'acorn-optional-chaining';

acorn.Parser.extend(optionalChaining).parse('a?.b?.c');
```

## License

This plugin is released under an [MIT License](./LICENSE).

It was based off the structure of [`acorn-numeric-separator`](https://github.com/acornjs/acorn-numeric-separator).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
