Dave Mitchell has requested an extension of $20,000 for his Maintaining the Perl 5 Core grant. This will allow him to dedicate another 400 hours to this work. During this grant he sent regular reports to the p5p mailing list as well as providing monthly summary reports that have been published on this site, the most recent of which are linked below:

Before we make a decision on this extension, we would like to have a period of community consultation. Please leave feedback in the comments field below or if you prefer, send email with your comments to makoto at perlfoundation.org. We request that all the feedback should be sent by January 15th.

If successful this extension will be funded from the Perl 5 Core Maintenance Fund.

I spent last the last two months:

* reworking list assignment (especially with an aggregate on the LHS) to
  be much faster in many cases. For example, this code is 33% faster in
  5.25.7 compared with 5.24.0:

    my @a;
    for my $i (1..10_000_000) {
        @a = (1,2,3);
        @a = ();
    }

* trying to reduce the overhead of compile time a bit;

* freeing up some uses of SV flags;

* fixing various assorted bugs as listed below;

Grant Proposal: Learning Perl 6, a book from O'Reilly Media

At the invitation of the TPF board, brian has withdrawn the grant proposal for the Learning Perl 6 book, and will submit a proposal to TPF on other ways for TPF to participate in enhancing the visibility of Perl 6.

The Grants Committee had a general discussion on funding activities whose output is not free of charge. TPF has documentation that states grant results must be "released under a publically available license that is free for redistribution and use without discrimination against field of endeavour" (from the "Grant Benefits" page), but the process of reviewing this proposal revealed that the documentation was easy to miss and not clearly stated as policy in the Grants Committee rules of operation. The committee unanimously agreed to update the rules to make it clear that all grant results should be available free of charge. We are in the process of adding such a clause to the rules of operation soon (wording may be slightly changed):

1.3. Grant proposals should mention how the grant results will be made available to the public. The grant results must be must be accessible free of charge.

Chad Granun reports on his work on the Test2 Manual grant. The last month was devoted to:

  • How to list the test tools in the modules dependencies;
  • Tutorial for TODO tests;
  • Tutorial for advanced test planning.

The Grants Committee is accepting grant proposals all the time. We evaluate them every two months and another evaluation period has come.

If you have an idea for doing some Perl work that will benefit the Perl community, consider sending a grant application. The application deadline for this round is 23:59 January 15th UTC. We will publish the received applications, get community feedback and conclude acceptance by January 25th.

To apply, please read How to Write a Proposal. Rules of Operation and Running Grants List will also help you understand how the grant process works. We also got some grant ideas from the community. The format is the same as the previous rounds in 2014-2016.

We will confirm the receipt of application within 24 hours.

If you have further questions, please contact me at tpf-grants-secretary at perl-foundation.org.
