Debugging

[DaniilMonin]

One of best feature of Jint was a debugger for scripts:

JintEngine engine = new JintEngine();
engine.SetDebugMode(true);

jint.Step += (sender, info) =>
{
   Console.WriteLine("{0}: Line {1}, Char {2}", info.CurrentStatement.ToString(), info.Location.Start.Line, info.Location.Start.Char);
};

But currently there no any out-of-box debugger (Jint.Debugger.DebugInformation) in Jint v.2 to get information about
a. Executed statement,
2. call stack,
3. local variables.

I would like to add myself to this request. The debugging feature was a quite unique and very good feature.

I'd love to see this feature again!

[Hooch180]

Me too.

We had been using this as well. We actually used it to stop executing a script if it was taking too long.

Hello! Do you have any plans to implement debug?

[sebastienros]

Right now I can't commit on this, but if anyone want to create a PR based on the previous implementation I'd be happy to take it in.

I added this feature. I'll tell you how in a separate "jint debugger" github.

Baisically, I added += Eventhandler in the engine.
Kindof 3 lines of code.

If you have a separate thread, you can listen to every executed line.
If you do an AutoResetEvent there, you can step-by-step debug all lines, and refer to the executed line.

Thanks alot. I'm looking for the next revision.

I submitted a PR to add the debug feature see PR #136

Hi I am new in here.

I tested Jint on few things and I liked it.
However what is missing is the ability to custom debug.
Jint is useful to extend applications, which also requires a mini IDE/Editor with a debugging feature.
This will help those who extend those applications to debug their code.

Looking forward for such a feature.

I am developing a Windows Service that is extended (thx Jint) using javascript and the point is that oftentimes I get TypeErrors and I don't have an easy way to know what was wrong. I think the debugging feature could help.

+1 I use Jint as an interpreter for customer's custom code. That way I can allow them to extend the functionality of my application. Often they are baffled when trying to debug their own extensions event with the amount of logs I provide them.
Ideally, I would like to add an option for them to debug their code.

I'll upload my debugger soon. Next week.

The following branch gives some code on how to add debugging support. Not complete but you should get the general idea.

Looking forward to see your implementation rolandroos...
