[ANN] dev-utils v1.0.1

Gavin Sinclair

10/12/2004 3:09:00 PM

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...

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', :pp # 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
>>self.class
Array

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

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

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.
