# Glob To Regular Expression

[![Build Status](https://travis-ci.org/fitzgen/glob-to-regexp.png?branch=master)](https://travis-ci.org/fitzgen/glob-to-regexp)

Turn a \*-wildcard style glob (`"*.min.js"`) into a regular expression
(`/^.*\.min\.js$/`)!

To match bash-like globs, eg. `?` for any single-character match, `[a-z]` for
character ranges, and `{*.html, *.js}` for multiple alternatives, call with
`{ extended: true }`.

To obey [globstars `**`](https://github.com/isaacs/node-glob#glob-primer) rules set option `{globstar: true}`.
NOTE: This changes the behavior of `*` when `globstar` is `true` as shown below:
When `{globstar: true}`: `/foo/**` will match any string that starts with `/foo/`
like `/foo/index.htm`, `/foo/bar/baz.txt`, etc.  Also, `/foo/**/*.txt` will match
any string that starts with `/foo/` and ends with `.txt` like `/foo/bar.txt`,
`/foo/bar/baz.txt`, etc.
Whereas `/foo/*` (single `*`, not a globstar) will match strings that start with
`/foo/` like `/foo/index.htm`, `/foo/baz.txt` but will not match strings that
contain a `/` to the right like `/foo/bar/baz.txt`, `/foo/bar/baz/qux.dat`, etc.

Set flags on the resulting `RegExp` object by adding the `flags` property to the option object, eg `{ flags: "i" }` for ignoring case.

## Install

    npm install glob-to-regexp

## Usage
```js
var globToRegExp = require('glob-to-regexp');
var re = globToRegExp("p*uck");
re.test("pot luck"); // true
re.test("pluck"); // true
re.test("puck"); // true

re = globToRegExp("*.min.js");
re.test("http://example.com/jquery.min.js"); // true
re.test("http://example.com/jquery.min.js.map"); // false

re = globToRegExp("*/www/*.js");
re.test("http://example.com/www/app.js"); // true
re.test("http://example.com/www/lib/factory-proxy-model-observer.js"); // true

// Extended globs
re = globToRegExp("*/www/{*.js,*.html}", { extended: true });
re.test("http://example.com/www/app.js"); // true
re.test("http://example.com/www/index.html"); // true
```
