+
+> Fast, pluggable and easy-to-use parser-renderer factory.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save snapdragon
+```
+
+Created by [jonschlinkert](https://github.com/jonschlinkert) and [doowb](https://github.com/doowb).
+
+**Features**
+
+* Bootstrap your own parser, get sourcemap support for free
+* All parsing and compiling is handled by simple, reusable middleware functions
+* Inspired by the parsers in [pug](http://jade-lang.com) and [css](https://github.com/reworkcss/css).
+
+## History
+
+### v0.5.0
+
+**Breaking changes**
+
+Substantial breaking changes were made in v0.5.0! Most of these changes are part of a larger refactor that will be finished in 0.6.0, including the introduction of a `Lexer` class.
+
+* Renderer was renamed to `Compiler`
+* the `.render` method was renamed to `.compile`
+* Many other smaller changes. A more detailed overview will be provided in 0.6.0. If you don't have to time review code, I recommend you wait for the 0.6.0 release.
+
+## Usage examples
+
+```js
+var Snapdragon = require('snapdragon');
+var snapdragon = new Snapdragon();
+```
+
+**Parse**
+
+```js
+var ast = snapdragon.parser('some string', options)
+  // parser middleware that can be called by other middleware
+  .set('foo', function () {})
+  // parser middleware, runs immediately in the order defined
+  .use(bar())
+  .use(baz())
+```
+
+**Render**
+
+```js
+// pass the `ast` from the parse method
+var res = snapdragon.compiler(ast)
+  // compiler middleware, called when the name of the middleware
+  // matches the `node.type` (defined in a parser middleware)
+  .set('bar', function () {})
+  .set('baz', function () {})
+  .compile()
+```
+
+See the [examples](./examples/).
+
+## Getting started
+
+**Parsers**
+
+Parsers are middleware functions used for parsing a string into an ast node.
+
+```js
+var ast = snapdragon.parser(str, options)
+  .use(function() {
+    var pos = this.position();
+    var m = this.match(/^\./);
+    if (!m) return;
+    return pos({
+      // `type` specifies the compiler to use
+      type: 'dot',
+      val: m[0]
+    });
+  })
+```
+
+**AST node**
+
+When the parser finds a match, `pos()` is called, pushing a token for that node onto the ast that looks something like:
+
+```js
+{ type: 'dot',
+  val: '.',
+  position:
+   { start: { lineno: 1, column: 1 },
+     end: { lineno: 1, column: 2 } }}
+```
+
+**Renderers**
+
+Renderers are _named_ middleware functions that visit over an array of ast nodes to compile a string.
+
+```js
+var res = snapdragon.compiler(ast)
+  .set('dot', function (node) {
+    console.log(node.val)
+    //=> '.'
+    return this.emit(node.val);
+  })
+```
+
+**Source maps**
+
+If you want source map support, make sure to emit the position as well.
+
+```js
+var res = snapdragon.compiler(ast)
+  .set('dot', function (node) {
+    return this.emit(node.val, node.position);
+  })
+```
+
+## Docs
+
+### Parser middleware
+
+A parser middleware is a function that returns an abject called a `token`. This token is pushed onto the AST as a node.
+
+**Example token**
+
+```js
+{ type: 'dot',
+  val: '.',
+  position:
+   { start: { lineno: 1, column: 1 },
+     end: { lineno: 1, column: 2 } }}
+```
+
+**Example parser middleware**
+
+Match a single `.` in a string:
+
+1. Get the starting position by calling `this.position()`
+2. pass a regex for matching a single dot to the `.match` method
+3. if **no match** is found, return `undefined`
+4. if a **match** is found, `pos()` is called, which returns a token with:
+  - `type`: the name of the [compiler] to use
+  - `val`: The actual value captured by the regex. In this case, a `.`. Note that you can capture and return whatever will be needed by the corresponding [compiler].
+  - The ending position: automatically calculated by adding the length of the first capture group to the starting position.
+
+## Renderer middleware
+
+Renderers are run when the name of the compiler middleware matches the `type` defined on an ast `node` (which is defined in a parser).
+
+**Example**
+
+Exercise: Parse a dot, then compile it as an escaped dot.
+
+```js
+var ast = snapdragon.parser('.')
+  .use(function () {
+    var pos = this.position();
+    var m = this.match(/^\./);
+    if (!m) return;
+    return pos({
+      // define the `type` of compiler to use
+      type: 'dot',
+      val: m[0]
+    })
+  })
+
+var result = snapdragon.compiler(ast)
+  .set('dot', function (node) {
+    return this.emit('\\' + node.val);
+  })
+  .compile()
+
+console.log(result.output);
+//=> '\.'
+```

+
+> Returns true if a value has the characteristics of a valid JavaScript descriptor. Works for data descriptors and accessor descriptors.
+
+## Usage
+
+```js
+const isDescriptor = require('is-descriptor');
+const assert = require('assert');
+
+assert.equal(isDescriptor({ value: 'foo' }), true);
+assert.equal(isDescriptor({ get() {}, set() {} }), true);
+assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
+```
+
+You may also check for a descriptor by passing an object as the first argument and property name (`string`) as the second argument.
+
+```js
+const obj = { foo: 'abc' };
+
+Object.defineProperty(obj, 'bar', {
+  value: 'xyz'
+});
+
+assert.equal(isDescriptor(obj, 'foo'), true);
+assert.equal(isDescriptor(obj, 'bar'), true);
+```
+
+## Examples
+
+### value type
+
+`false` when not an object
+
+```js
+assert.equal(isDescriptor('a'), false);
+assert.equal(isDescriptor(null), false);
+assert.equal(isDescriptor([]), false);
+```
+
+### data descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+assert.equal(isDescriptor({ value: 'foo' }), true);
+assert.equal(isDescriptor({ value() {} }), true);
+```
+
+`false` when the object has invalid properties
+
+```js
+assert.equal(isDescriptor({ value: 'foo', enumerable: 'baz' }), false);
+assert.equal(isDescriptor({ value: 'foo', configurable: 'baz' }), false);
+assert.equal(isDescriptor({ value: 'foo', get() {} }), false);
+assert.equal(isDescriptor({ get() {}, value() {} }), false);
+```
+
+`false` when a value is not the correct type
+
+```js
+assert.equal(isDescriptor({ value: 'foo', enumerable: 'foo' }), false);
+assert.equal(isDescriptor({ value: 'foo', configurable: 'foo' }), false);
+assert.equal(isDescriptor({ value: 'foo', writable: 'foo' }), false);
+```
+
+### accessor descriptor
+
+`true` when the object has valid properties with valid values.
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {} }), true);
+assert.equal(isDescriptor({ get() {} }), true);
+assert.equal(isDescriptor({ set() {} }), true);
+```
+
+`false` when the object has invalid properties
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {}, enumerable: 'baz' }), false);
+assert.equal(isDescriptor({ get() {}, writable: true }), false);
+assert.equal(isDescriptor({ get() {}, value: true }), false);
+```
+
+`false` when an accessor is not a function
+
+```js
+assert.equal(isDescriptor({ get() {}, set: 'baz' }), false);
+assert.equal(isDescriptor({ get: 'foo', set() {} }), false);
+assert.equal(isDescriptor({ get: 'foo', bar: 'baz' }), false);
+assert.equal(isDescriptor({ get: 'foo', set: 'baz' }), false);
+```
+
+`false` when a value is not the correct type
+
+```js
+assert.equal(isDescriptor({ get() {}, set() {}, enumerable: 'foo' }), false);
+assert.equal(isDescriptor({ set() {}, configurable: 'foo' }), false);
+assert.equal(isDescriptor({ get() {}, configurable: 'foo' }), false);
+```
