How is the debug support coming along?
Today I have checked in a basic version but I have wasted time on a try
to change the threading model of ruby-debug. Therefore the integration
is still very basic.
Nevertheless you can run a scenario which shows the stack frames and the
variable view. Threading is not correctly supported yet which means that
all existing threads are shown but they do not display the correct stack
frames. Only the suspended thread (e.g. the one where the breakpoint
occurred) shows its stack frames along with its variables. Sometimes the
connection between debug view (where the stack frames are displayed) and
the editor does not work and external sources are not found. Stepping,
at least "Step over" should be OK, too.
I have attached a patch which integrates the debug support into
RadRails. It is just meant to be an idea of how it could work and
replaces the functionality of the start action for the WEBrick server.
As opposed to the current implementation it uses a launch configuration
to start the server. Do you think it would make sense to switch to
launch configurations also for the regular start-up? It would give
further configuration options for the users.
Here is a direction if you want to give it a try (I would be interested
if it works on OSX, I have tested only Linux so far):
1) Check out RDT trunk or use a nightly build not older than
0.8.0.611191859NGT (you currently have to download from
http://213.239.199.113:8080/cruisecontrol/buildresults/RDT, since the
upload from the build server to our official update site is out of order)
2) Install ruby-debug gem from org.rubypeople.rdt.launching
3) Apply patch to RadRails
4) Startup RDT/RadRails
5) Switch on ruby-debug in Preferences->RDT->Debugger
6) Set a breakpoint in a controller
7) Start WEBrick server
8) Call controller with URL => RDT will ask to switch to Debug perspective
cheers
