+
+Error handling for Vinyl plugins.
+
+## Usage
+
+```js
+var PluginError = require('plugin-error');
+
+var err = new PluginError('test', {
+  message: 'something broke'
+});
+
+var err = new PluginError({
+  plugin: 'test',
+  message: 'something broke'
+});
+
+var err = new PluginError('test', 'something broke');
+
+var err = new PluginError('test', 'something broke', { showStack: true });
+
+var existingError = new Error('OMG');
+var err = new PluginError('test', existingError, { showStack: true });
+```
+
+## API
+
+### `new PluginError(pluginName, message[, options])`
+
+Error constructor that takes:
+* `pluginName` - a `String` that should be the module name of your plugin
+* `message` - a `String` message or an existing `Error` object
+* `options` - an `Object` of your options
+
+**Behavior:**
+
+* By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
+* If you pass an error object as the message the stack will be pulled from that, otherwise one will be created.
+* If you pass in a custom stack string you need to include the message along with that.
+* Error properties will be included in `err.toString()`, but may be omitted by including `{ showProperties: false }` in the options.

-# through2
-
-[![NPM](https://nodei.co/npm/through2.png?downloads&downloadRank)](https://nodei.co/npm/through2/)
-
-**A tiny wrapper around Node streams.Transform (Streams2/3) to avoid explicit subclassing noise**
-
-Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
-
-Note: As 2.x.x this module starts using **Streams3** instead of Stream2. To continue using a Streams2 version use `npm install through2@0` to fetch the latest version of 0.x.x. More information about Streams2 vs Streams3 and recommendations see the article **[Why I don't use Node's core 'stream' module](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html)**.
-
-```js
-fs.createReadStream('ex.txt')
-  .pipe(through2(function (chunk, enc, callback) {
-    for (var i = 0; i < chunk.length; i++)
-      if (chunk[i] == 97)
-        chunk[i] = 122 // swap 'a' for 'z'
-
-    this.push(chunk)
-
-    callback()
-   }))
-  .pipe(fs.createWriteStream('out.txt'))
-  .on('finish', () => doSomethingSpecial())
-```
-
-Or object streams:
-
-```js
-var all = []
-
-fs.createReadStream('data.csv')
-  .pipe(csv2())
-  .pipe(through2.obj(function (chunk, enc, callback) {
-    var data = {
-        name    : chunk[0]
-      , address : chunk[3]
-      , phone   : chunk[10]
-    }
-    this.push(data)
-
-    callback()
-  }))
-  .on('data', (data) => {
-    all.push(data)
-  })
-  .on('end', () => {
-    doSomethingSpecial(all)
-  })
-```
-
-Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
-
-## API
-
-<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
-
-Consult the **[stream.Transform](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
-
-### options
-
-The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
-
-The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2({ objectMode: true, allowHalfOpen: false },
-    (chunk, enc, cb) => {
-      cb(null, 'wut?') // note we can use the second argument on the callback
-                       // to provide data as an alternative to this.push('wut?')
-    }
-  )
-  .pipe(fs.createWriteStream('/tmp/wut.txt'))
-```
-
-### transformFunction
-
-The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
-
-To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
-
-Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
-
-If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
-
-### flushFunction
-
-The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
-
-```js
-fs.createReadStream('/tmp/important.dat')
-  .pipe(through2(
-    (chunk, enc, cb) => cb(null, chunk), // transform is a noop
-    function (cb) { // flush function
-      this.push('tacking on an extra buffer to the end');
-      cb();
-    }
-  ))
-  .pipe(fs.createWriteStream('/tmp/wut.txt'));
-```
-
-<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
-
-Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
-
-```js
-var FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
-  if (record.temp != null && record.unit == "F") {
-    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
-    record.unit = "C"
-  }
-  this.push(record)
-  callback()
-})
-
-// Create instances of FToC like so:
-var converter = new FToC()
-// Or:
-var converter = FToC()
-// Or specify/override options when you instantiate, if you prefer:
-var converter = FToC({objectMode: true})
-```
