Hi all,
Has anyone written anything that will skip all the gem related code
that occurs on startup when running a profiler over a program? Is it
even possible?
All that extra stuff in the final output makes it harder to read and
generally bugs me.
Regards,
Dan

An excerpt from the README of ruby-prof:
==================================================
=== ruby-prof API
The second way is to use the ruby-prof API to profile
particular segments of code.
require ‘ruby-prof’
RubyProf.start
…
[code to profile]
…
result = RubyProf.stop
printer = RubyProf::TextPrinter.new(result)
printer.print(STDOUT, 0)
Alternatively, you can use a block to tell ruby-prof what
to profile:
require ‘ruby-prof’
result = RubyProf.profile do
…
[code to profile]
…
end
If for some reason you want to use profile.rb, it’s easy to hack up to
have the same feature (let me know and I’ll send it).

Oh, excellent Joel, thank you. As for profile.rb, I think it would be
great to send that as a patch to ruby-core.

I haven’t experienced that myself, and it has been less than a year
since the last release. However, I do see a bunch of bugs in the queue
that haven’t been touched, so I dunno.
Shugo, Charlie - you around?

Setting that up is trivial with Ruby Performance Validator.

Is RubyProf still being maintained? It has this horribly annoying
bug where it breaks when you return after calling RubyProf.start.
The pure-ruby profile.rb works correctly, Shugo’s prof (RubyProf’s
ancestor) works correctly, and zenprofile (from ZenHacks) works
correctly.
Hi Daniel and Eric,
Yup still around (just a few months behind schedule :).
The bug is fixed in ruby-prof 0.5.0, which is now available on
ruby-forge.
