[ANN] ruby-debug 0.1.3

kent · July 12, 2006, 6:17pm

Hello Everyone,

I’m pleasant to announce the release of ruby-debug 0.1.3.

If you think that ruby-breakpoint is too limited for your needs and
debug.rb brings your application to its knees, you might find
this small extension useful.

INSTALL

It’s a usual procedure:

$ gem install ruby-debug

DOCS

This library has almost identical interface with the standard
debug.rblibrary.

Also you can check out my little tutorial at

Cheers,
Kent.

Hello Kent,

This is great. Thanks for writing it.

One request I have, is that a carriage return with nothing on the line
run the
last next or step command. This is something I’m used to from the perl
debugger, which makes it nice to single step through your script.
Otherwise,
it’s a pain to have to type “n\n” or “s\n” to step through the script.

Regards,
Blair

Blair,

You are right, for some reason it slipped from the original
implementation. I’ve added it back.

Thank you.

This flat-out rocks. IÂ¹ve been happily developing sans debugger but the
print-statement route does presume you know the right things to print
out.
Reconstructing the steps to a given bug can be time consuming if you
have
the wrong set of print statements (read logger.debug calls) in place.
IÂ¹ll
probably rely on the typical logger.debug and log tailing for most work,
but
this will certainly take the pain out of the hard-to-track bugs.

Thanks for this.

I’m unfortunately shackled on a Windows box for a good portion of my

Unfortunately, I don’t have access to the Windows development
environment.
If somebody could make a precompiled gem, I would be more than happy to
make
it available for install.

Peña,
No, it’s not. There is an almost identical library bundled with Ruby
called debug.rb which is pure ruby. It’s just much slower.

Jonas,

I don’t see this warning. Are you using gcc 4.0.0? It seems that in
gcc 4.0.1 and higher this warning is suppressed by default. It is also
possible to suppress it with -fno-strict-aliasing. Anyway, I bet that
you should see this warning a couple of times when you compile ruby,
since I copied this particular usage from the ruby’s source code.

Thanks. I’ve removed these warnings in the latest version. For some
reason my ruby was compiled without -Wall.

Hi Kent,

I use gcc 4.0.3 (Ubuntu 4.0.3-1ubuntu5)

In any cases this is not a problem for me. I just though you could
find this interesting

The only other gem compiled lib I use is mongrel and I don’t have that
output but I don’t know if it’s because it doesn’t use the same code
of if it was corrected.
