Projects we know about now
The exact projects that we’ll be working on depend on who shows up, but here are some likely candidates. If you’d like your project listed here, email a short paragraph about it to email@example.com.
Perl 6 & Parrot
Perl 6 is the next release of Perl 5, and is quite an undertaking. Parrot is the virtual machine that underlies Perl 6, and will allow other languages to run on top of it.Chip Salzenberg, the pumpking for Parrot, will be at the hackathon to organize this effort. We’ve got a laundry list of tasks, include
- Working as a group on one subsystem to be named later, e.g. I/O or exceptions
- C code cleanups
- Name standardization
- Function call overhauling
- Fix C namespace pollution to make Parrot clean for embedding
- Adding tests
- Automatic code generation
- Static code analysis with lint and splint
- Dynamic code analysis with valgrind and other testing tools
- Improve test coverage
- Other Parrot Cage Cleaners work
Perl 5 tests
Steve Peters has been doing a yeoman’s job of closing Perl bug tickets, but, as he notes:
There have been many times where bugs were fixed, but the bug reports stayed open because there was no test case to add to the Perl core. I’ll be working to convert as many bug reports as possible into test cases and add them back to the Perl core. I’m also hoping to fix a few of the bugs along the way, combine duplicate reports, and otherwise clean up the bug queue even further than my previous work has done.
This is a great example of a project where anyone can help, because much of it is testing and rerunning test cases, peperhaps on multiple platforms, with little or no coding involved. It will also be a great learning experience.
HTML::Tidy is a wrapper around the libtidy validation and cleanup library. It needs some serious attention to increase the access to the inherent capabilities of libtidy. If you know C and XS, this could be the one for you.
Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine, like lint for C. New policies are getting added to Perl::Critic all the time, and you can help your fellow Perl programmers write cleaner, safer code.
