Grant Conclusion Report
Shlomi Fish has sent a Grant Conclusion Report:
> This is a final report of my grant of improving the Perl built-in debugger
> (invoked using `perl -d` on the command line with code residing in
> `lib/perl5db.pl` and tests in `lib/perl5db.t`), by adding more tests and
> refactoring it.
> The grant was completed mostly successfully, after the number of test
> assertions in `lib/perl5db.t` was increased to 108, and the debugger's core
> code (in `lib/perl5db.pl`) has been made more modular and elegant. The reason
> it was not a full success is because the debugger's code is still not as
> elegant as it could be, but part of the problem was my desire not to break
> bug-to-bug backwards compatibility of CPAN and darkpan modules that make
> use of the debugger's internal API.
> During the grant, my grant manager, Alan Haggai Alavi, published
> several reports on the TPF blog on my behalf:

> During the grant I have learnt what `git rebase` was all about, how to use
> it, and why it was sometimes a good idea, and also became familiar with more
> features of the debugger.
> If anyone is interested in a more modular debugger for Perl, while doing away
> with backwards compatibility, they can look at `Devel::Trepan`:
> * [http://metacpan.org/module/Devel::Trepan](http://metacpan.org/module/Devel::Trepan)
> * [http://github.com/rocky/Perl-Devel-Trepan](http://github.com/rocky/Perl-Devel-Trepan)
> Otherwise, the refactored debugger should be more amenable to changes, and
> the additional test assertions will better ascertain it is not going to be
> broken as easily.
> I would like to thank Alan Haggai Alavi (my grant manager), Father
> Chrysostomos ( [https://metacpan.org/author/SPROUT](https://metacpan.org/author/SPROUT) - for applying some of my
> changesets and for fixing a bug or two I discovered), Ricardo Signes (the
> perl 5 pumpking), Rocky Bernstein (for writing `Devel-Trepan` and commenting
> on the grant reports), and the other perl5-porters.
> I am planning on continuing working on the perl debugger, and other parts
> of the perl 5 core after the end of the grant, but I thank the Perl Foundation
> for giving me the grant, which has motivated me.
