Re: [Pharo-users] Debugger question

Yeah there was a bug report about stepping on Processor terminateActive. I tried with the latest Pharo VM and I was able to do Cmd . to interrupt. It worked several times, but it might be just a question of luck. It is not easy to fix. We could as a temporary patch hardcode the step over terminateActive ... 2013/6/1 phil(a)highoctane.be <phil(a)highoctane.be> > When using the debugger, I am often getting into the situation shown in > the attached picture when stepping. > > And the image is then frozen.

I don't know about C++ but for Java there are libraries like CGLib[1] or ASM[2] that can manipulate/generate classes/interfaces at runtime. However the operation is not even remotely like editing code! It's writing code to change or generate the bytecode.

Considering myself a "Pharo Consultant", two things are happening to me. And maybe some other are in the same situation. Maybe we are poor at selling ourself. But it may be (as my case) because we don't need it now :) For example I don't want to advertise myself if I know I won't be able to have free time for the next months. So...maybe the fact that consultants are quite is because they have too much work hehehe. At least myself, if I need more work (if I have free time), I would send an email to the mailing list. On the other hand, we, consultants, should not only think in the near future but also in the long term. So even if may not be able to have free time in the short term, we should marketing us a bit better. So....where should be add ourself and describe a bit our expertise? -- Mariano http://marianopeck.wordpress.com

Debugger question

by phil＠highoctane.be

When using the debugger, I am often getting into the situation shown in the attached picture when stepping. And the image is then frozen. No matter how much Cmd-. I do, no way out it seems. For newcomers, this is really discouraging I think. What can we do to alleviate this? Thx, Phil
