The status of smartmatch came up. It is in a weird position where it used to be part of the language, then was retroactively declared an experiment, then deprecated and slated for removal, and now it’s no longer being removed – in fact we’ve added a feature for it, and not an experimental one either. The bottom line is that it’s not deprecated any more and not experimental either, but is now just a negative feature like indirect and multidimensional: it’s a mistake we made that will remain part of older language versions but will not be included in future feature bundles.
Release blocker triage continues as ever. Quite a few new issues came in recently, of which we identified two issues and one pull request as blockers. One of the issues and the PR pertain to the documentation of the status of smartmatch; we expect that there may be more inconsistencies in the documentation which will need to be ironed out.
Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This sixth post introduces you to subroutine invocation in XS.
This is a hybrid (in-person and virtual) conference being held in Austin, TX on July 3rd-4th.
Did you miss your chance to speak or have wish to speak at the only available Perl Science Track (and get published in the Science Perl Journal)? Or maybe you just can't get enough Perl this summer??? Submit here ... or get more information on the PCC, including registration, special event registration, and donation links click here. For questions you may email us at science@perlcommunity.org or find us in the Perl Applications & Algorithms discord server.
The following lengths will be accepted for publication and presentation:
Science Perl Track: Full length paper (10-36 pages, 50 minute speaker slot)
Science Perl Track: Short paper (2-9 pages, 20 minute speaker slot)
Normal Perl Track (45 minute speaker slot, no paper required)
You may ask, where is the Winter SPJ or videos? We are working on them, promise! (it's a lot of work as some of you know. See also on Perlmonks and r/perlcommunity.
A Futility Closet post references a Perl "poem" over two decades old. I remember chuckling at it when it first appeared. Although it was published "anonymously", I'm pretty sure I know who wrote it. :)
Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This fifth post introduces you to subroutine(method/function) prototypes in XS.
This weekend I was once again privileged to attend the Perl Toolchain Summit (PTS). This year it was held in the lovely city of Leipzig.
The PTS continues to be my favourite technical event of the year. In part this is because I get to meet old friends and make new ones, but it's also because the summit really serves its purpose and I am able to make so much progress on the projects I have which belong in Perl's toolchain ecosystem.
PTS isn't a conference - it's a four-day working meeting. It brings together people working on toolchain projects to solve common problems and push the work forward. I did get a lot of work done, but that's not the main focus, for me anyway. I see it as a time to solve problems and plan the way forward, and for me PTS facilitates that in the most wonderful fashion.
Parenting aint easy. Certainly it is often something your kids teach you.
Even worse, it often starts with “<INSERT_KIDS_FRIENDS_NAME>’s dad lets
him do <INSERT_CURRENTLY_PROHIBITED_ACTIVITY>”. In this constant battle
to shape your offspring into a model citizen, with the values you value,
and turning him/her into a self-sustaining organism, one applies tools
that enhance particular features, remove the superfluous or the undesirable.
Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This fourth post introduces you to overloading operators in XS.
All of us showed up for a long meeting of identifying release blockers. First we went over the issues and PRs submitted since last week, none of which turned out to be new potential blockers. Then we examined all of the issues and PRs of interest we had previously identified. We applied the “Release Blocker” label where necessary, left comments, and merged a few of the PRs. Out of 20 issues and 11 PRs on our list, we identified 5 issues and 1 PR as blockers, of which the PR and several of the issues all pertain to the same problem with retention of errors on filehandles across I/O operations. This issue needs an informed decision, which we did not have the time for in this meeting, but will pursue next.
Yes, this is a Mandelbrot fractal with three heads. No cloning needed, just multiply z to the power of four and proceed as usual. Well all this and so much more contains the latest release of Juliagraph 0.7. Intro here. All I wrote about the Cellgraph and Harmonograph applies again, more features, better controls and ... you can cruise the fractal by mouse.
Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This third post introduces you to list context in XS.
CVE-2024-56406 is published and has been addressed by new point releases. Please upgrade or patch your perl promptly if affected. We thank Steve Hay, Andreas König and Stig Palmquist for doing the heavy lifting, as well as Nathan Mills for discovering the problem, and Karl Williams for providing the fix. We re-/learned a number of old and new lessons about the handling of security issues, which we will write up as new process for the PSC, the Perl Security Team, and the CPANSec group, to be jointly reviewed and agreed at the looming PTS.
We started winnowing this release cycle’s pull requests for potential release blockers. We briefly reviewed all 72 pull requests and identified 11 of interest for a closer look.
We reviewed the 2 new issues filed since last week for release blocker potential and put one of them on our list for closer review. We then started a closer examination of the 20 issues we identified as candidate blockers. We got through 5 issues, none of which we considered blockers.
One of my pleasures in perl is learning the C language again. Something about the perl language makes it easier to write C, but while sharing the same space in my brain.
So how can I write a trivial program to write exactly one GB (2^30) of data to disk?
first in perl- (Of course you prototype in perl!)
But since my c program is cleaner, here’s the C program
Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This second post introduces the fundamentals of type checking variables in XS.
Lots has been going on. All of us showed up, though Aristotle had to join late and Philippe had to leave early, so the meeting was short but productive:
We continued with the potential release blocker issue review and finished going over all 49 issues remaining at this time, of which we identified 11 of interest. There are now still 72 pull requests to review.
We agreed to include the new Perl logo in the next release, but don’t yet know exactly how and where. That should be sorted out on p5p, and we will kick that off soon.
We went over the latest point release news, where everything is finally on track. It is coming very soon.
