Moonscript ctags regexes

Installation

Save .ctags to ~/.ctags or append it to the end of your existing ~/.ctags.

If you use Tagbar for Vim add the contents of .vimrc to ~/.vimrc

Example Coverage

These regexes should cover all of the following:

Classes

class MyAwesomeClass                         # tag = MyAwesomeClass
class my_Class                               # tag = my_Class
class Namespace.MyClass                      # tag = MyClass
class Namespace.Child extends Namespace.Base # tag = Child

Methods / Functions

doIt: ->                # tag = doIt
zip = ->                # tag = zip
fooBar: (param) ->      # tag = fooBar
bazZoo: => x * x        # tag = bazZoo

Variables / Fields

my_Var = 'foo'     # tag = myVar
@local_Var = 'bar' # tag = localVar
prop: 'bar'        # tag = prop
@bam: 'zoo'        # tag = bam

Variables / Fields declared within the parameter list of new()

new: (@foo) ->                # tag = foo
new: (@bar, @zip) ->          # tags = bar, zip
new: (@prop = {}) ->           # tag = prop
new: (@baz={}, @me = 'foo') -> # tags = baz, me
