in reply to I usually debug via...

I usually don't debug, because I write tests beforehand, and code in small units. Hence, it's very rare for me to have bugs.

There :-P

(OK, OK, If I really have to, I resort to print)

    Here! Here! Write Tests before you write code! Use iterative incremental development cycles! cog++

    Ok, so when I'm up against a wall, I use print. Sometimes when my eyes just do not see the obvious mistake, I'll come to SoPW.

    May the Force be with you

    Gotta question re: unit tests. In C or C++, I'd do something like this in a foo.c/foo.cpp file:

    #define FOO_UNIT_TEST
    (various functions or objects... )
    #ifdef FOO_UNIT_TEST
    int main (int argc, char ** argv) {
    (code that tests the above )
    #endif
    
    --then I'd just compile the one file when testing, or comment out the first line when integrating.

    Is there a similar mechanism for Perl?

    but what about maintenance programming and debuging the work of mortal (wo)men
      Then I guess print combined with Data::Dumper is my tool of choice :-)

[Mj1234]: Hello Monks, I have installed Active perl 5.16 and 5.14 but I dont find Devel::GDB package when I try to install through ppm
[Discipulus]: i'v installed ubuntu 16.04lts and i'm quite disappointed: is deadly simmilar to new win osses where you cannot find even simple things...
[Corion]: Hi Discipulus ;)
[Corion]: Mj1234: Maybe Ubuntu didn't package Devel::GDB? In that case, consider using local::lib and install the module from CPAN
[Corion]: But a quick Google search turns up this page, which seems to suggest that it should be packaged
[Discipulus]: iirc active perl has repositories only for last 2 o 3 major release of perl Mj1234. I strongly suggest portable version of strawberry perl and use cpan client to install modules
[choroba]: Also, who needs GDB when there's hdb?
