[IronPython] Debugging IronPython script code

[Rainer Worbis]

My initial question was if it is possible to debug code that  is
executed with ScriptSource.Execute(string) - so I do not have a file.

If having a file is important I can 'in debug mode' save my code before
executing.

To answer your question - if I use a filename (ex.: 'C:\Temp\script.py')
I can set breakpoints there - and they will stop execution.

Only when using 'System.Diagnostics.Debugging.Break()' only a decompiled
code is shown. Using this Code is preferred because I normally do not
have the script beforehand - it is partly generated.

How is the filename specified in the Create call?  Is it a full path?
If you just open the file in VS does VS recognize the code (e.g. can you
set breakpoints)?

Now is't working partly - i used a app.config  <microsoft.scripting
debugMode="true"> which apearently does not setup debugging right.

What is not working is that I get only a disassembly  - no source code
attached.

Is there something to setup before?

Oh, sorry, it looks like it needs to be a bool, not "true" in quotes...
With that in mind this works for me:

 

        Dictionary<String, object> options = new
Dictionary<string,object>();

        options["Debug"] = true;

        ScriptEngine engine = Python.CreateEngine(options);

        ScriptSource source =
engine.CreateScriptSourceFromFile("C:\\Users\\Dino\\test.py");

        source.Execute();

 

I can put breakpoints in test.py and hit them.

No - i get the Call Stack showed below 

 

[Lightweight Function]

If you right click in the call stack window and check Show External Code
do you see the code then?

I got as far as that - when the breakpoint is hit - VS pops up but not
in some python code but in the call  to Execute - the python code is
marked as external code.

So is there a possibility to have VS show the script code?

You can set DebugMode = true on a ScriptRuntimeSetup object.  If you're
using the Python class you can pass a Dictionary object to CreateRuntime
with "Debug" = "true" and we'll set it for you.

Hallo all,

 

is there a possibility to debug IronPython code that is executed with
ScriptSource.Execute or CompiledCode.Execute within VisualStudio?

Setting breakpoints in the python code will can be done by
System.Diagnostics.Debugger.Break() - the code breaks but I don't know
how to tell VS to get into my code.
