method_source
=============
(C) John Mair (banisterfiend) 2010
_retrieve the sourcecode for a method_
*NOTE:* This is nothing fancy; it simply utilizes `Method#source_location`
in Ruby 1.9
`method_source` is a utility to return a method's sourcecode as a
Ruby string. Also returns `Proc` and `Lambda` sourcecode.
It is written in pure Ruby (no C).
`method_source` provides the `source` method to the `Method` and
`UnboundMethod` and `Proc` classes.
* Install the [gem](https://rubygems.org/gems/method_source): `gem install method_source`
* Read the [documentation](http://rdoc.info/github/banister/method_source/master/file/README.markdown)
* See the [source code](http://github.com/banister/method_source)
Example: methods
----------------
Set.instance_method(:merge).source.display
# =>
def merge(enum)
if enum.instance_of?(self.class)
@hash.update(enum.instance_variable_get(:@hash))
else
do_with_enum(enum) { |o| add(o) }
end
self
end
Limitations:
------------
* Only works with Ruby 1.9+
* Cannot return source for C methods.
* Cannot return source for dynamically defined methods.
Possible Applications:
----------------------
* Combine with [RubyParser](https://github.com/seattlerb/ruby_parser)
for extra fun.
