Ruby on Rails PL Forum

Sounds great! How about thursday (20th may) evening then?
We could have fun with your debugger and then do some hacking session, or just grab a beer at the nearby bar.

WRUG guys, interested?

I like the idea and will be there.

See you at Euruko 2010 . I use debugger very rarely now but when I do it's priceless and no one can tell me that unit tests can replace that

Hi -

Any word on where we will be meeting 20 May, this Thursday? 

Best way to contact me directly before Thursday is rocky@gnu.org. Starting Thursday, you can reach me at the handphone (cell phone) number +44 7540 503697.

It would be nice to have contact information in case I get lost or the flight is delayed. (There have still been small amounts of volcano ash floating around.) 

I assume the location has a projector that I can plug my laptop into.

Just for your information, I'll be staying at the Aparthotel Zgoda, near the Palac Kultury i Nauki.

Look forward to meeting everyone!

Thanks to Aenima for hosting my Ruby 1.9 debugger talk, and especially to Tomash (to whom I also owe a beer) for making it all happen. Thanks to everyone coming to the event. WRUG in Warsaw rivals its counterpart Ruby group in New York City!

I received many very useful comments which I will use to give a better talk at EuRuKo. For this, I am yet again grateful.

Below I summarize some of the comments I remember. I often get things wrong which is why I write debuggers in the first place. So please feel free to correct or add your thoughts. Send the comments to rocky@gnu.org. If you want to send them in Polish that's okay too since I can use Google Translate.

- Less improvisation. I will stick to more to a scripted talk. This is crucial since I need to get more information conveyed in less time.

- The fumbling between Emacs sessions is really bad. So I will to get to the talk early and have things better set up before the talk.

- Describe the use case where debuggers are helpful. Don't assume anyone know anything about ruby-debug.

More interesting demos:
- stopping before a return and changing the value of the return. 
- capturing method class and module definitions from irb.
- stopping before an exception.
- tracing into function defined via eval.

Less interesting demos:

- timing of different implementations of "step over"
- nested debugging.

Demos not shown (but might include)
- calling the debugger from inside an irb session
- cebugging a rails app or, more generally calling the debugger from a Ruby program
- showing after-the-fact trace output.
- loading the debugger at some arbitrary point in a program

Will do.. Thanks.

It'd great if you could include these two in your presentation.

This could be an eye-opener for all who don't believe in debuggers. ;-)
