[ANN] dev-utils v1.0.1

[Gavin Sinclair]

Hi folks,

This is a very minor update on dev-utils v1.0, released last week.
There are a couple of documentation updates, but the only important
difference is a tarball for installation.

http://rubyforge.org/frs/download.php/1678/dev-utils-1.0.1.tgz

Cheers,
Gavin

About dev-utils:

With dev-utils/debug you can:

* Escape to an IRB session from a running program.

breakpoint
breakpoint 'Person#name' # Identify it when it happens.
breakpoint { @name } # Default return value.

* Access a no-config logfile for debugging.

debug 'Database connection established' # Look in ./debug.log

* Trace expressions in that logfile.

trace 'x + y'
trace 'Process.pid'
trace 'names', p # Pretty-print.
trace 'page_structure', :yaml # YAML representation.

Is it possible to have breakpoint open the IRB session within a
particular object?

require 'dev-utils/debug'

a = [1, 2, 3]
breakpoint a

I tried to use the gem and got the following error,
any idea?

[root@sith]# gem install dev-utils
Attempting local installation of 'dev-utils'
Local gem file not found: dev-utils.gem
Attempting remote installation of 'dev-utils'
Install required dependency extensions? [Yn] y
ERROR: While executing gem ... (Gem::FormatException)
Error reading files from gem

Hi George. It looks like you're runnning Rubygems < 0.8.0. Is that
right? If so, you need to upgrade to 0.8.1 to use newly released
gems:

$ gem install rubygems-update
$ update_rubygems

Thanks,
Chad

You are of course right Thank you for your help and the nice lib!

Not at the moment, but it's very easy to implement. Is that something
you want?

I think so.

I don't know if this was mentioned before, but even though there is no
need for default configuration, it would be nice if there was a way to
change the debug log if necessary. For instance if your running two
different ruby scripts in the same directory that both use debug.log is
there a way to specify a different log name for each one? No
configuration necessary by default is great but there are cases it
becomes necessary.

Btw It would be nice if the error was more helpful, ie something like:

This gem was packaged by another version

or something...

It's planned. The fact that someone actually wants it (for personal
use, I couldn't care less) will hurry it up

I think that dtermining a version mismatch from this error would be
quite hard...
But it could be useful if when getting remote gems the rubygems
application checked that it version was the latest one.

In future RubyGems versions, we can do this. The problem is that
0.7.0 never imagined that 0.8.0 would come along and change its
format. So as far as 0.7.0 knew, the new gems were corrupt. We can
change this for later releases, but we can't fix 0.7.0 without having
people upgrade.

In short, I agree

I think so.

Would you be okay with doing breakpoint(nil, obj.sendbinding))?

I don't think it is possible to get access to outer variables when using
a changed object, however.
