CoffeeScript mixin doesn't work -


i found example of mixins in coffeescript faq seems doesn't work.

am missing here?

extend = (obj, mixin) ->   name, method of mixin     obj[name] = method  include = (klass, mixin) ->   extend klass.prototype, mixin  class button   onclick: -> alert "click"  class events include button, events  (new events).onclick()  # => uncaught typeerror: object #<events> has no method 'onclick'

fiddle

you missing fact onclick defined on prototype of button, , did not set arguments right order in include function

extend = (obj, mixin) ->   name, method of mixin     obj[name] = method  include = (klass, mixin) ->   extend klass.prototype, mixin  class button   onclick: -> alert "click"  class events include events,button.prototype  (new events).onclick()

see "fiddle"

so mixin snippet works pretty well.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
