Hello, I'm looking for a program to profile my non-rails ruby program...
I found ruby-prof, can that do the job? if it does, I have no idea how
to install and run it to profile my programs =(

Thanks for your help

ruby-prof is excellent and can do the job for you.

Quick start:
  gem install ruby-prof
  ruby -runprof mycode.rb

(unprof.rb is a wrapper script that profiles your code and drops
profiling output in the current directory)

gem install ruby-prof

ruby-prof my-prog.rb

See ruby-prof -h for optoins. The -p graph_html option is nice. I've been a very happy user of ruby-prof.

There is also "-r profile" (no gem needed):

robert@fussel ~
$ ruby -r profile -e '10.times {|i| puts i}'

I wrote a series of short articles about using ruby-prof a while ago,
and they still seem pretty popular. Perhaps these will help:

On Ruby: ruby-prof and call graphs

I'm sorry to say that those articles didn't help...I'm trying to run
ruby-prof on a program saved onto the desktop... where do I go to type
in the command(s) and what commands should I type?

Thanks

Wow, what an answer...

When you said "RubyGems Package Manager" looks like you're running
Windows and you have One-Click Installer "installed".

Just jump into a command prompt and see if "ruby -v" get you the ruby
version installed, if so, that means you have Ruby in your PATH.

First you need to get your feets wet with command line, 'cd' into your
desktop folder (whatever is that, you should know) and try running the
suggested commandline from the articles.

HTH,

Create shortcut on desktop, answer the first question with "cmd"
(without quotes).
Name it as you wish. When created, open its properties, and replace
%windir% with
%homedrive%%homepath% (no spaces between %%). Save.

Now you can click on it and a dos/cmd window appears.

Alternative way is Start menu, Accessories, command prompt, (window
appears), %homedrive%<enter>
cd %homepath%\Desktop<enter>

or replace %homedrive% and %homepath% with actual values (C:,
\documents and settings\<your user name>)
