+# call-signature [![Build Status](https://travis-ci.org/jamestalmage/call-signature.svg?branch=master)](https://travis-ci.org/jamestalmage/call-signature)
+
+> Parse / Generate Method Signatures
+
+
+## Install
+
+```
+$ npm install --save call-signature
+```
+
+
+## Usage
+
+```js
+var signature = require('call-signature');
+
+// parse a call signature definition
+var parsed = signature.parse('t.equal(expected, actual, [message])');
+
+console.log(parsed);
+/* =>  
+       {
+         callee: {
+           type: 'MemberExpression',
+           object: 't',
+           member: 'equal'
+         },
+         args: [
+           {
+             name: 'actual',
+             optional: false
+           },
+           {
+             name: 'expected',
+             optional: false
+           },
+           {
+             name: 'message',
+             optional: true
+           }
+         ]
+       }
+*/
+
+
+// Create signature definitions from the parsed object.
+signature.generate(parsed);
+
+//=> "t.equal(expected, actual, [message])"
+```
+
+
+## API
+
+### callSignature.parse(input)
+
+#### input
+
+Type: `string`
+
+A string that matches the call signature spec:
+
+`object.member(required_arg1, required_arg2, [optional_arg1])`
+`name(required_arg1, required_arg2, [optional_arg1])`
+
+`object`, `member` and `name` can be any identifiers, but currently the callee must be a `MemberExpression` or an `Identifier` (that requirement may loosen in the future).
+ 
+You can have any number of arguments. Optional arguments are denoted by placing the argument name between square `[`brackets`]`.
+
+#### returns
+
+A simple JS Object with three properties `callee` and `args`.
+
+`callee` will be an object containing `type` property and its corresponding properties.
+
+when matched against `MemberExpression` like `foo.bar(baz)`, `object` and `member` will be strings.
+
+    callee: {
+      type: 'MemberExpression',
+      object: 'foo',
+      member: 'bar'
+    }
+
+when matched against `Identifier` like `foo(baz)`, `name` will be string.
+
+    callee: {
+      type: 'Identifier',
+      name: 'foo'
+    }
+
+`args` will be an array. Each item of the array will have two properties `name`, and `optional`. 
+ `name` will be the `string` name of the arg. `optional` will be a boolean value.
+
+### callSignature.generate(parsed)
+
+#### input
+
+Type: `Object`
+
+Must have the same definition as the return value from the `parse` method.
+
+#### returns
+
+A `string` signature definition that will parse to exactly the provided input.
