Raku

Raku did the thing that Python had not done for me, bring­ing the joy of pro­gram­ming and the ex­pres­sive­ness of code back to the fore­front. It is a lan­guage that em­braces mul­ti­ple par­a­digms, al­low­ing you to write code in a way that feels nat­ural to you.

Getting Started

• Rakudo.

Review

• same spirit as Perl: fun to write but not too fun to read.
• there are so many ways to do the same thing. kinda like nat­ural lan­guages
• many in­trigu­ing syn­tax
• type sys­tems
  • re­minds me a lot of dlang with flex­i­ble type / value con­straints.
• the de­sign of op­er­a­tors is beau­ti­ful, el­e­gant, flex­i­ble and fun to play with.

Testing

• Use Use Test, then there are many rou­tines we can use such as is, ok …

Editor Support

• It’s very slow on vim/​neovim (as re­ported here: lag while scrolling us­ing de­fault con­fig­u­ra­tion · Issue #35 · Raku/vim-raku · GitHub ) to the point that it made me aban­don this lan­guage.
  • MatchParen is soooo slow when ft=raku · Issue #12168 · vim/​vim · GitHub
  • Syntax hi­light ran­domly breaks · Issue #22 · Raku/vim-raku · GitHub
• I will re­visit it when things be­come bet­ter; this is re­ally a deal breaker.
