Re: retrieving line number in case of error - "simple debugger"

Thanks for answer.

The example will be copied in Source Forge tomorrow.

Well, I conclude that as I thought, things are not that easy.

Let me open the topic, then.

Tcl is widely used to let end-users write scripts that impact a big C/C++ application.
I myself currently develop a sort of modeler for physical models, that will involve both a GUI and a Tcl-based end-user language.

The Tcl-based language will let the user decribe the model, by calling C routine that will build the model in memory (hope it is clear enough).
The scripts will be written within a text canvas holded by the GUI, and interpreted through a TclInterp ran by the GUI.

I really think that such a use of Tcl is not rare at all.

The general problem is then :
Given the fact that the end-user is not a technician, one need to offer him basic and 'usable' debug facilities.

Now, the general question :
- what are the 'debug' facilities developpers usually offer to their non-technician end-users ?
- how are they built ?

I am quite sure that a large, large knowledge and knowhow is available on that question. But i can't find it (in the wiki, the archives, the tips, etc.)

All the best !

My two question are :

2/ Do you know a nice HOWTO or code sample for building basic debug features ?

I started to answer, then discovered the details later in your
article that you know all the answers I was about to give. 

Please copy that example into the Tcl Feature Request Tracker
where I can more carefully look into it over time.  The details
involve enough time and effort that articles here will expire.

I suspect this is a limitation of the bytecode compiler, but
possibly something we can improve.
