As lizmat++ is currently enjoying a well-deserved rest in the Caribbean, today’s Weekly is guest-written by a Zoffix! Hopefully, it’s still going to be good…
It’s been a slow week, as many Sixers are attending the Free and Open Source Software Developers’ European Meeting (FOSDEM). As was mentioned in an earlier Weekly, there will be some Perl 6 talks. The videos for them already started rolling in: Perl 6 on Jupyter by Brian Duggan (slides and code).
So far, the event seems to be going well:
<tyil> the perl stand at fosdem was awesome, much more people that
showed interest in Perl 6 than I imagined
2018.01 Rakudo Star Binaries, Still Pending
This week, 48 tickets were handled, with 26 of them resolved.
- ash++ implemented a
- nine++ made several improvements to start up speed, by improving code of
CompUnit::PrecompilationUnit::deserialize, as well as moving setup of certain objects like
$*VMto compile time (this work is still ongoing)
- MasterDuke++ continued working on implementing JIT templates for various ops, merging 30 more this week.
- ugexe++ fixed CompUnit::RepositoryRegistry to point to correct location for home repository
- samcv++ added support for windows-1251 (Cyrillic) encoding on both MoarVM and JVM backends, and fixed several bugs in windows-1252 encoding with several characters not being correctly encoded
- pmurias++ continued working on the JS backed, dealing with utf8-c8 encoding
- Kaiepi++ improved docs and
Configure.ploption for building MoarVM
- jstuder-gh++ fixed a bug with
statevariables inside a
- titsuki++ and jnthn++ de-bittrotted nqp repository’s files and documentation
- dogbert17++ fixed segfaults when errors were encountered while opening
- brrt++ added a NOOP expr JIT operator
- timotimo++ made sure PHI were not output into expr JIT log as well as made a proposal for datagram-oriented API for UDP sockets
- zoffix++ redesigned the
HyperWhatevercurrier, fixing a number of bugs, as well as making nested
Whateverclosures faster to compile and run (a 5-arg
Whatevernow runs 2.2x faster and compiles 8% faster). He also made
.=method calls 39x-64x faster.
Other assorted work core devs performed included:
- Fixed a bug in
sorting a 2-element list with arity-2 sorter
- Fixed crashes in compile-time executed
- Changed semantics of
:bquoter tweak, to behave more like
- Fixed bogus error in REPL when a
Junctionwas a result of the expression
- Fixed crash with
ENTERphaser nested inside
- Fixed crash in
Learning Perl 6
The Learning Perl 6 book by brian d foy has reached a milestone in its production: all of the research has been completed. All that remains to do is cleaning everything up and doing a bit of rework on some chapters.
ash++ continued the DAILY Perl 6 Inside Out blog posts (while also writing for the Russian-language perl6.ru):
- 40. Substitution and balanced brackets in Perl 6 regexes
- 41. Converting Num to Rat in Perl 6
- 42. Mathematics in the Num data type in Perl 6
- 43. Variable $y not declared. Did you mean $x?
- 44. Exploring the pick and the roll methods in Perl 6, part 1
- 45. Exploring the pick and the roll methods in Perl 6, part 2
- 46. How does ‘pick’ return unique elements (Exploring the pick and the roll methods in Perl 6, part 3)
That’s about it for the week! Hope you enjoyed the guest-written Weekly. It’s a tough job writing these, so be sure to thank lizmat++ for doing them.
