Flectioned now includes a TracedException class that provides stack trace information.

sample:
# import cn.kuehne.flectioned;
#
# class MyException : TracedException{
#    this(char[] message){
#       super(message);
#    }
# }
#
# void foo(int i){
#    if(i > 0) {
#       foo(i - 1);
#    } else {
#       throw new MyException("message");
#    }
# }
#
# void main(){
#    foo(2);
# }

# Error: (sample.MyException) message
#    0xFC8967F0   0x804F612   void sample.foo(int)
#    0xFC8967F8   0x804F5F1   void sample.foo(int)
#    0xFC896800   0x804F5F1   void sample.foo(int)

This is just awesome! Very nice, thomasK :)

If you compile with -version=TraceAllExceptions all Exceptions(object.Exception and derived classes) will be traced.

sample:
# import cn.kuehne.flectioned;
# import std.utf, std.stdio;
#
# void main(){
#    try{
#       toUTF16("a\xFFb"c);
#    }catch(Exception e){
#	writefln("(%s) %s", e.classinfo.name, e);
#       foreach(step; TracedException.retraced[e]){
#          writefln("%s", step);
#       }
#    }
# }

dmd -version=TraceAllExceptions sample.d && ./sample

# (std.utf.UtfException) 4invalid UTF-8 sequence
# 0xFFCA5438      0x8061716       dchar std.utf.decode(char[], uint*)
# 0xFFCA546C      0x8061E09       wchar[] std.utf.toUTF16(char[])
# 0xFFCA54A8      0x804ADF6       int main(char[][])
# 0xFFCA54D8      0x80513AF       extern(C) int main(int, char**)

Good work Mr. Kuehne!
I would like to see this in phobos (I hope Mr. Bright is reading this thread :)

It sure would be nice to have a stack trace printed by default.  Most of the time I fire up windbg with D, it's to trace an Access Violation. This would make debugging D apps ten times faster.  And much less painful.

Why not incorporate that backtrace patch someone posted into Phobos?

Shinh's only works on win32 , its still very useful , but this code works on linux + win32.

I'd really love to see this for tango also.

We are planning to add this in the 0.96 timeframe, but are dependant on Thomas porting it to Tango for us :)

Because nothing that anyone writes for Phobos ever seems to make it in.  :\

(A notable exception would be std.cpuid.)

Well... I did manage to get a change to the GC incorporated (setting array.length = 0 no longer invalidates the allocated RAM), so keep on lobbying <G>.
