free-swig/lib/tags/autoescape.js

A simple, powerful, and extendable templating engine for node.js, similar to Django, Jinja2, and Twig.

const utils = require('../utils');
const strings = ['html', 'js'];

/**
 * Control auto-escaping of variable output from within your templates.
 *
 * @alias autoescape
 *
 * @example
 * // myvar = '<foo>';
 * {% autoescape true %}{{ myvar }}{% endautoescape %}
 * // => &lt;foo&gt;
 * {% autoescape false %}{{ myvar }}{% endautoescape %}
 * // => <foo>
 *
 * @param {boolean|string} control One of `true`, `false`, `"js"` or `"html"`.
