Real world ruby programs to learn from

Fernando Perez

9/30/2008 1:10:00 PM

Hi,

Can you recommend some Ruby projects in which I can have a look to learn
good Ruby practices / idioms and why not contribute to them? I am fed up
with the stupid code examples we find in books.

The Ruby on Rails code is a bit too complex to start with I guess.

I think http://pl... is the site you need to visit.

Your link seems very interesting and cool to learn from and can very
very helpful to jump from one language to another.

I had a quick look at
http://pleac.sourceforge.net/pleac_ruby/processmanageme... and
I must say this is far from correct or ideal. Issues I have spotted
on first check:

readme = IO.popen("ls") # does not use block form

$stdout = writeme # must be $stdout.reopen(writeme)

Process.waitpid(pid, 0) # should come after the read loop otherwise
deadlock may occur

Kind regards

Robert , pleac is "a work in progress" . Anyone can make contributions
to it . It would be great if you would submit corrections to bugs you
found , if you can spare the time , of course .

Argh too bad there are not always good coding practices, that's a reason
why I avoid looking at refactormycode for instance, there are too many
funky solutions proposed.

I submitted some suggestions a few years ago, I think involving
switching something so that it used a block, and I was told that that
wouldn't be good because it wasn't similar enough to other languages
to compare.

I got the impression that pleac was mostly Perl being written in a
variety of languages, but I haven't looked at it in a while.

Dear Fernando,

I think a good place to look at many solutions to many problems and sometimes very
insightful comments is the Rubyquiz site:

Actually, just this once I would not recommend the rubyquiz site - the
programs there aren't written with an eye on maintainability.

I agree with martin. There are only a handful of quizes that have
real-world applicability, and of the answers to those, only a small
percentage exhibiting good coding practices (my own included).

If someone hasn't already mentioned this, look at some of the stdlib
code, and cast your glance over the many projects on rubyforge.
