gulp-match ![status](https://secure.travis-ci.org/robrich/gulp-match.png?branch=master)
==========

Does a vinyl file match a condition?  This function checks the condition on the `file.path` of the
[vinyl-fs](https://github.com/wearefractal/vinyl-fs) file passed to it.

Condition can be a boolean, a function, a regular expression, a glob string (or array of glob strings), or a stat filter object

Used by [gulp-if](https://github.com/robrich/gulp-if) and [gulp-ignore](https://github.com/robrich/gulp-ignore)

## Usage

```javascript
var gulpmatch = require('gulp-match');
var map = require('map-stream');

var condition = true; // TODO: add business logic here
var options = null; // Optionally pass options to minimatch

vinylfs.src('path/to/file.js')
  .pipe(map(function (file, cb) {
    var match = gulpmatch(file, condition, options);
    if (match) {
      // it matched, do stuff
    }
    cb(null, file);
  }));
```

## API

### file

A [vinyl-fs](https://github.com/wearefractal/vinyl-fs) file.

### condition

#### boolean condition

```javascript
var match = gulpmatch(file, true);
```

if the condition parameter is `true` or `false`, results will also be `true` or `false`.

#### function condition

```javascript
var match = gulpmatch(file, function (file) {
  return true;
})
```

if the condition parameter is a function, it will be called, passing in `file` passed to gulp-match.

#### regular expression condition

```javascript
var match = gulpmatch(file, /some\/path\.js/);
```

If the condition is a regular expression, it will be evaluated on the `file.path` passed to gulp-match.

#### glob condition

```javascript
var match = gulpmatch(file, './some/path.js');
```
```javascript
var match = gulpmatch(file, ['./array','!./of','./globs.js']);
```

The globs are passed to [minimatch](https://github.com/isaacs/minimatch).  If the glob matches (or any of the elements in the array match), gulp-match returns `true` else `false`.

#### stat filter condition

```javascript
var match = gulpmatch(file, {isFile:true});
```
```javascript
var match = gulpmatch(file, {isDirectory:false});
```

If the condition is an object with a `isFile` or `isDirectory` property, it'll match the details on the
[vinyl-fs](https://github.com/wearefractal/vinyl-fs) file's [`stat`](http://nodejs.org/api/fs.html#fs_class_fs_stats) object.

#### else

```javascript
var match = gulpmatch(file, 42);
// match = true
```
```javascript
var match = gulpmatch(file, '');
// match = false
```

If there's no matching rule from the rules above, it'll return `true` for truthy conditions, `false` for falsey conditions (including `undefined`).

### options

#### minimatch options object

See <https://github.com/isaacs/minimatch> for options docs.
