This week’s Perl and Raku Conference 2022 in Houston was packed with great pre­sen­ta­tions, and I humbly added to them with a five-​ish minute light­ning talk on two of Perl’s more mis­un­der­stood func­tions: map and grep.

Sorry about the um”s and ah”s…

I’ve writ­ten much about list pro­cess­ing in Perl, and this talk was based on the fol­low­ing blog posts:

Overall I loved attend­ing the con­fer­ence, and it real­ly invig­o­rat­ed my par­tic­i­pa­tion in the Perl com­mu­ni­ty. Stay tuned as I resume reg­u­lar posting!

Update for Raku

On Twitter I nudged promi­nent Raku hack­er (and recov­ered Perl hack­er) Elizabeth Mattijsen to write about the Raku pro­gram­ming language’s map and grep func­tion­al­i­ty. Check out her five-​part series on DEV.to.

I’m busy this week host­ing my par­ents’ first vis­it to Houston, but I didn’t want to let this Tuesday go by with­out link­ing to my talk from last week’s Ephemeral Miniconf. Thanks so much to Thibault Duponchelle for orga­niz­ing such a ter­rif­ic event, to all the oth­er speak­ers for com­ing togeth­er to present, and to every­one who attend­ed for wel­com­ing me.

After a lot of pro­cras­ti­na­tion, I’ve decid­ed my talk for this week’s ePhEmeRaL mini­conf will be Cunningham’s Law: A Year of Being Wrong on the Internet, or «prêch­er le faux pour savoir le vrai.»

The event starts at 8:00 AM CST on Thursday, November 18; you can find out more about it includ­ing the full sched­ule and a time zone con­vert­er here.

Look, I get it. You don’t like the Perl pro­gram­ming lan­guage or have oth­er­wise dis­re­gard­ed it as dead.” (Or per­haps you haven’t, in which case please check out my oth­er blog posts!) It has weird noisy syn­tax, mix­ing reg­u­lar expres­sions, sig­ils on vari­able names, var­i­ous braces and brack­ets for data struc­tures, and a menagerie of cryp­tic spe­cial vari­ables. It’s old: 34 years in December, with a his­to­ry of (some­times ama­teur) devel­op­ers that have used and abused that syn­tax to ship code of ques­tion­able qual­i­ty. Maybe you grudg­ing­ly accept its util­i­ty but think it should die grace­ful­ly, main­tained only to run lega­cy applications.

But you know what? Perl’s still going. It’s had a steady cadence of year­ly releas­es for the past decade, intro­duc­ing new fea­tures and fenc­ing in bad behav­ior while main­tain­ing an admirable lev­el of back­ward com­pat­i­bil­i­ty. Yes, there was a too-​long adven­ture devel­op­ing what start­ed as Perl 6, but that lan­guage now has its own iden­ti­ty as Raku and even has facil­i­ties for mix­ing Perl with its native code or vice versa.

And then there’s CPAN, the Comprehensive Perl Archive Network: a continually-​updated col­lec­tion of over 200,000 open-​source mod­ules writ­ten by over 14,000 authors, the best of which are well-​tested and ‑doc­u­ment­ed (apply­ing peer pres­sure to those that fall short), pre­sent­ed through a search engine and front-​end built by scores of con­trib­u­tors. Through CPAN you can find dis­tri­b­u­tions for things like:

All of this is avail­able through a mature instal­la­tion tool­chain that doesn’t break from month to month.

Finally and most impor­tant­ly, there’s the glob­al Perl com­mu­ni­ty. The COVID-​19 pan­dem­ic has put a damper on the hun­dreds of glob­al Perl Mongers groups’ mee­tups, but that hasn’t stopped the year­ly Perl and Raku Conference from meet­ing vir­tu­al­ly. (In the past there have also been year­ly European and Asian con­fer­ences, occa­sion­al for­ays into South America and Russia, as well as hackathons and work­shops world­wide.) There are IRC servers and chan­nels for chat, mail­ing lists galore, blogs (yes, apart from this one), and a quirky social net­work that pre­dates Facebook and Twitter.

So no, Perl isn’t dead or even dying, but if you don’t like it and favor some­thing new­er, that’s OK! Technologies can coex­ist on their own mer­its and advo­cates of one don’t have to beat down their con­tem­po­raries to be suc­cess­ful. Perl hap­pens to be battle-​tested (to bor­row a term from my friend Curtis Ovid” Poe), it runs large parts of the Web (speak­ing from direct and ongo­ing expe­ri­ence in the host­ing busi­ness here), and it’s still evolv­ing to meet the needs of its users.

I’ll be run­ning a work­shop based on my recent Blogging Outside the Bubble webi­nar dur­ing Developer Career Day 2021, which is run­ning from August 6 through 7. It’s free to reg­is­ter, with top speak­ers and prac­ti­cal career discussions.
