= event_hook
* http://rubyforge.org/projects/seattlerb
== DESCRIPTION:
Wraps rb_add_event_hook so you can write fast ruby event hook
processors w/o the speed penalty that comes with set_trace_func (sooo
sloooow!). Calls back into ruby so you don't have to write C.
% ruby demo.rb
# of iterations = 1000000
user system total real
null_time 0.120000 0.000000 0.120000 ( 0.125279)
ruby time 0.560000 0.000000 0.560000 ( 0.562834)
event hook 3.160000 0.010000 3.170000 ( 3.175361)
set_trace_func 34.530000 0.100000 34.630000 ( 34.942785)
== FEATURES/PROBLEMS:
* Simple subclass design. Override ::process and you're off.
* Filters on calls/returns to not bog down on extraneous events.
* Not sure why process needs to be a class method. Will fix eventually.
== SYNOPSIS:
class StupidTracer < EventHook
self.process(*args)
p args
end
end
== REQUIREMENTS:
* RubyInline
== INSTALL:
* sudo gem install event_hook
