Perl 6 / Raku. The swiss army chainsaw (Perl) raised to the power of the swiss army chainsaw. For its expressiveness in spite of some learning curve.
- raffraffraff 2y agoI had to take a look at some examples, because my last Perl work was over 15 years ago. This is neat: grammar Parser { rule TOP { I <love> <lang> } token love { '♥' | love } token lang { < Raku Perl Rust Go Python Ruby > } } say Parser.parse: 'I ♥ Raku'; # OUTPUT: ｢I ♥ Raku｣ love => ｢♥｣ lang => ｢Raku｣ The same thing in other languages would require a lot more code, without a parser module. An LLM tells me that functional languages can handle this stuff well too, but that Raku code is just extremely simple to grasp
- creer 2y agoSo to be fair, "extremely simple to grasp" because looked at superficially. Once you dig into it, there is a lot happening in there. Both in what can go into an actual production grammar, and what is present in the parsing output. which is why I was mentioning learning curve. But yeah, most stuff is easy, there is more than one way to do it, and the impossible isn't. Or something.
