Submit Raku talks for The Perl & Raku Conference (June 27–29, 2025 in Greenville, SC)

codesections
commented

The Call for Presentations for The Perl & Raku Conference is now open – so everyone should start thinking about what Raku talks they'd like to give. Lets make this the year where more Raku talks are proposed than Perl talks! (#friendlyrivalry)

The conference website also has more info about TPRC in general. Hope to see you there!

It appears to be a custom, unnamed theme built for Chroma. Here are the css values it uses.

"The Best Regex Trick" in Raku

codesections
commented

Nice! Your answer inspired me to post my own. I went with 

(\['"Tarzan"', 'Tarzan', '"Tarzan and Jane"'\] «\~\~» / '"Tarzan"' || ('Tarzan') /)»\[0\]

Or, for total overkill (and poor performance): 

my &infix:<\~\~\[0\]> = \*\[0\] ∘ &\[\~\~\];  
('"Tarzan"', 'Tarzan', '"Tarzan and Jane"') «\~\~\[0\]» / '"Tarzan"' || ('Tarzan') /;

[edit: gosh, I don't post on Reddit for a little while, and they go and switch their default editor to a non-markdown version!]

Infix repetition precedence

codesections
commented

Raku basically uses this approach with different spelling: && is high precedence whereas and is low precedence (and the same for ||/or and !/not, etc). So your last example could be written as: 

a && b or c && !d

One observation from having lived with this system in real code: Although in theory it "eliminate[s] the need for brackets", in practice, Raku conditionals still end up using brackets somewhat often for added clarity. The two levels of precedence do reduce the number of brackets, though.
