Timo is still not completely well. However, he has been able to make good progress:

  1. Optional parametres are now correctly logged

  2. Fixed a crash caused when the profiler is used on multithreaded code

Jonathan Worthington recently requested an extension of his Perl 6 Performance and Reliability Engineering grant.

I'm pleased to announce that the Board of Directors approved extension of another $10,000. It'll allow him to dedicate another 400 hours to this work. Additional $210 of expense was approved to cover the wire tranfer fee from the past payments and the next payment.

I would like to thank the community members who took time to comment on this grant extension request and our sponsors who made funding the grant possible through our Perl 6 Development Fund.

I also appreciate Jonathan Worthington's continued work.

Timo Paulssen is recovering from a repetitive strain injury, and has not been able to start work on the grant yet. While waiting for the condition to get better, Timo has been watching videos related to the technologies he will be using.

Moving apartments in January has been another issue bothering Timo. Timo is very eager to start working on the grant as soon as he is able to.

Jonathan Worthington has requested an extension of $10,000 for his Perl 6 Performance and Reliability Engineering grant. This will allow him to dedicate another 200 hours to this work.

His previous work was successfully delivered as reported in the latest report.

This funding will come from the Perl 6 Core Development Fund. Will Coke Coleda agreed to continue the grant manager's role.

Before we make a decision on this extension we would like to have a period of community consultation that will last for seven days. Please leave feedback in the comments or, if you prefer, email your comments to makoto at

Final Report : Grant "Robust Perl 6 Unicode Support"

1 Comment

Samantha has submitted her last grant update and her final review of her work for the consideration of the community and the Grants Committee.

Highlights for the latest month of work include:

  • Her Unicode Collation Algorithm is fully merged into MoarVM
  • She has released full UCA documentation
  • Prepends are handled with more generality, so that edge cases in certain ops now work properly
  • Bugs in encoding into and handling UTF8-C8 have been squashed

In the Final Report section, Samantha reviews her many achievements and deliverables. These can be compared to the inchstones and goals of her original proposal.

The Grants Committee would appreciate comments regarding this grant and its state of completion before it votes on whether to approve the work and proceed to payment. Please make any such comments to this post.


In her excellent overview of Unicode presented at YAPC-EU, Samantha gives us her take on Perl6 Unicode:

Torture the implementers for the sake of the users.

Perl6 Unicode users will certainly have some wonderfully easy access to deep Unicode magic thanks to her work. But reading her blog, I get a distinct impression of delight, rather than torture...

In her complete blog post, she describes, among other details:

  • Implementation of the Knuth-Morris-Pratt algorithm for native Unicode string searches, along with grapheme caching, to improve search times over the current flat string implementation.

  • Further documentation work and helpful scripts.

She is down to final documentation activities and merges.

Samantha also notes: "If other Perl 6 devs or users of the community want to make any requests for Unicode or string related documentation, you can send me an email or send me a message on freenode IRC (nick samcv)."


Unicode membership

No Comments

I'm pleased to report that The Perl Foundation has renewed its associate level membership in the Unicode Consortium.

This membership allows Perl core developers to be on the "inside track" when it comes to the future of Unicode standards. It also gives them access to documents and people that have made the development of Unicode support in Perl easier.

The Perl Foundation is pleased to be able to make this resource available through the generosity of all of our sponsors.
