Earlier today I saw an interesting talk at a meeting of the
NY Perl Mongers in which Rocky Bernstein highlighted some of his recent work
creating a GDB-like debugger for Perl. While
Perl does ship with its own integrated debugger, which can be invoked with the –d
switch, the Devel::Trepan module demonstrated appears to have great potential
for turning into a Perl debugger that could one day rival or even exceed the
current Perl debugger. The Trepan module
borrows much of its command set from the GDB debugger, which many users who
have migrated to Perl from C\C++ might find helpful. Moreover, the debugger as demonstrated, while
still a work in progress, already appears to be functional enough to begin to
be evaluated as a serious possibility for use in debugging tasks. This is a
module that I will definitely be taking a closer look at in the near future and
one that I think would be worth it for other Perl programmers to take a look at
as well. More information on the module
can be found at https://github.com/rocky/Perl-Devel-Trepan.
