Patrick Böker has published a Raku module (called Rainbow) that parses Raku source code and provides a tokenised version of the code which can be used to provide syntax highlighting.

This now gives two ways of providing Raku syntax highlighting. The other one being RakuAST::Deparse::Highlight which has a finer granularity and also works on localized code, but requires the code to be compilable.

All in all, TIMTOWTDI!

Core Developments

• Timo Paulssen fixed an issue with the new “in-situ” strings on 32-bit systems in MoarVM, fixed a CVE in minilua that is unlikely to affect MoarVM, and brought nqp-configure up-to-date.
• Elizabeth Mattijsen (micro-)optimized the use of various adverbs on [...] and {...} postcircumfixes, making some cases up to 7x as fast (but most of them only a few %).

In RakuAST developments this week:

• Elizabeth Mattijsen fixed various deparsing and highlighting issues and gave up on supporting Rakudoc markup in syntax highlighting.
• The number of passing test-files with the new Raku grammar are now 142/153 (make test +0) and 1158/1355 (make spectest +0).

Winding down

Syntax highlighting! Fast but incomplete. Or slow and precise. Both have their uses! Meanwhile, still: Слава Україні!  Героям слава!

Please keep staying safe and healthy, and keep up the good work!
