While a number of intended deliverables for remain unmet, he's made significant contributions to the expression backend and has identified unexpected roadblocks to the remaining tasks that should yield to additional preparatory work. In light of this, the Grants Committee will be considering Bart's report below and voting on a payment for the currently accomplished work of 50% of the original amount requested. The Grants Committee will consider a revised

Bart gave me this interim report on his grant: is essentially complete. Bart is currently finishing floating point support in conditional expressions. This is surprisingly nontrivial, he indicates, because of NaN, and because of condition code differences between floating point and integer comparisons. is nearing completion. Bart says it turned out to have a whole lot of overlap with the floating point support. He

Bart reports the latest progress: Fixed a few windows-specific bugs Assigned a permissible-register set to live ranges, which makes it possible to combine values with distinct register requirements Ensured that when a value is spilled to make place for another, the released register is actually one that the new value can use. In other words, a bunch of register allocator work. Floating point support is close to being finished. He

Bart received helpful comments on his blog posts last month that will move him ahead with intermediate representation optimization and register allocation. He writes: I'm still working on finalizing the floating point support for the JIT compiler, but I've also started work on the new register allocation algorithm. This wasn't strictly a deliverable, but I expect it will help the deliverable of improving code generation. MAJ

Brrt reports that February was busy and short, but that he did some research on other implementations of register allocation that he can apply to MoarVM JIT. He notes the following conundrum that he has been thinking about. Maybe a reader can advise: I've also encountered a limitation in the optimization of the IR, which I'm trying to resolve. The issue is this, if I have a bunch of code

Brrt is untangling the intricacies of floating point expressions so close to the metal in his He provides some of his insights Here is his brief report Last month, I've been busy with floating point support. Getting that ready involved two things: Getting the type system for the expression template precompiler ready. This works now, I'm happy with the result. Fixing the register allocator to support it. This works as

Back in August 2018, André Walker reported on his initial work to revitalize the revitalizing of blogs.perl.org. He made the following report to the TPF Grants Committee on 14 Aug 2018 The latest report as of this post can be found here. Short update regarding grant progress. I have most of the major features I wanted to implement already in place, even if some are a bit rough. So it's

He made the following report to the TPF Grants Committee on 3 Jan 2019 I will also backpost another report André made to the Committee in Aug 2018 shortly. The work I set out to do for the grant on blogs.perl.org is almost complete. Here is a breakdown of what is done, what is missing for a first

Brrt has hit the ground running on his MoarVM JIT Compiler grant. Here is his interim report: I wanted to start with floating point support, which has two subtasks: Ensure that DynASM encodes SSE instructions with variadic registers correctly. Ensure that the JIT itself accepts and works with floating point registers. I finished the first two of those tasks. For some context, x86-64 instruction encoding rules require an extra byte

JJ Merelo has completed work on his grant, and has published his final report. The Grants Committee is now reviewing and voting on payment. The Committee welcomes your comments as they deliberate. MAJ

Tina Müller has provided her final report of her work on her grant Complete YAML::PP. The Grants Committee is now evaluating and voting on final payment. The committee welcomes your comments here as they deliberate. Please comment here rather than on the gist. MAJ

We call him... The Closer. JJ made 324 commits in May on top of the 195 in April to https://github.com/perl6/doc, and is now as the top closer of issues in the repo. He also sketched out most of the missing pages in the the Perl6 Docs Roadmap. That enabled that albatross to be tossed overboard as well. JJ has also written a couple of metadocuments, describing patterns he has observed

JJ has made impressive progress on the backlog of documentation issues as part of his grant. He has already addressed and closed twice as many issues as all those closed by others. In doing so, he has committed about as many times as all other contributors to the repo. While addressing issues, JJ performed some additional housecleaning and put in some quality time at StackOverflow. You can read all the

Tinita spent about 25 hours coding YAML::PP during March. She emitted a production release at YAML::PP 0.006, which incorporates items from her previous reports, adding Writer and Representer objects, a nice Dumper, and cyclic reference detection. In a spirit of multi-cultural outreach and understanding, she also made her first PR to PyYAML. You can read all the details in her latest report. MAJ

Tinita spent about 20 hours coding YAML::PP this month. To her growing YAML bibliography, she has added "Strings in YAML To Quote or not to Quote". Here Tina shows very clearly that Ingy's ultimate goal was to write the Kobiyashi Maru of format specifications.

Tinita spent about 10 hours coding YAML::PP this month. Additional integration of YAML Schemas into YAML::PP is percolating, and she is making deep dives into the YAML 1.2 spec where angels fear to tread. Read her latest report for details. MAJ

More good stuff this month from Tinita on the grant Complete YAML::PP. She explains the YAML schema concept and its evolving flavors in this interesting post. This lays the foundation for understanding the schema features added to the YAML::PP loader. Tina also fixed a couple of problems in YAML::XS. An important one security-wise is that now you can turn off loading into Perl objects by default when using !!perl/.. schema

Tinita, the one-woman YAML ecosystem, continues apace with her grant Complete YAML::PP. Find her latest report on her blog. She is making headway on some of the cooler features of YAML: flow style, anchors, and special tags. Legit boolean behavior is now implemented in YAML::XS.

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

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 inchstones are falling like 1F030—1F09F as Samantha makes further progress on her grant to improve the robustness of Unicode support in Rakudo. In her complete blog post, she describes: Implementation of a fully working Unicode Collation Algorithm with only 82 of 190,377 tests failing 100% of Emoji 4.0 emoji are treated as a single grapheme, enabling MoarVM to advertise full Unicode 9.0/Emoji 4.0 text segmentation support.

Samantha continues to address the addition of Unicode features and long-standing Unicode bugs in her grant to improve the robustness of Unicode support in Rakudo. In her complete blog post, she describes: the Unicode collation algorithm in a very readable overview, and her improvements to enable customizable collation at all three main collation levels support for the Prepend property in code that avoids grapheme breaking, leading to increases in

Samantha McVey has made progress on her grant to improve the robustness of Unicode support in Rakudo.
