Extending Pharo Debugger

Hello,

I'm working on the Pharo debugger, and I wanted to add a button with new functionality just besides the buttons "Proceed" "restart" ...

Is there an easy way to do it? Which is the class that I have to Modify/Extend in order to do that?

I tried to look around the methods and I found where DebugSession is created, but I didn't see any clear reference to the UI or to how is constructed in it.

Thank you in advance,

Matteo

Re: Extending Pharo Debugger

Hi Matteo,

If you look, for example at RestartDebugAction, there is on

the class side a method #gtStackDebuggingActionFor: that

has the annotation <gtStackDebuggingAction>.

To attach actions to the stack (proceed, resume, step into)

the debugger looks for subclasses of DebugAction that have

class side methods annotated with gtStackDebuggingAction.

These methods can optionally receive the debugger instance

as an argument. However you can also only have simple

methods like 'PeelToFirstDebugAction class>>#gtActionType'

Cheers,

Andrei

Re: Extending Pharo Debugger

While you are at it, make a button at the top with "Run to cursor". It is a missing one that requires oneto get the context menu to execute. Annoying.

Re: Extending Pharo Debugger

Hello Stephan,

In the work for my thesis, I'm building a debugger for big data applications, that when a bug happens doesn't stop the computation but proceeds evaluating the next data. This opens a series of debuggers in separate threads, that are shown one by one. I added a button that allows me to restart and automatically proceed all the waiting debuggers from a certain point of the stack (assuming that the stack has the same "shape"), so basically after I fix a bug in the first debugger I can say to the others: ok, the bug is solved, restart yorself and proceed.

The thing seems more or less to work, except some details that I still have to implement.

Re: Extending Pharo Debugger

It looks fun :)

Are you looking for more ideas for your thesis?
