Re^4: sourcefilter with complete parser?

[raiph]

My theory is that it's pretty feasible to create a new language which is a subset of Perl5 or Perl6 and creates acceptable JS.

Have you considered helping Pawel Murias, Jimmy Zhuo, Reini Urban, Zaki Mughal, Tokuhiro Matsuno et al progress the JS backend for NQP? Note that while that project's main goal is to compile Rakudo Perl 6 to JS (which is why the repo is called rakudo-js), the interim goal is to compile the much simpler NQP to JS and (based on comments by pmurias) the project is quite close to achieving this lesser goal.

Achieving this lesser goal would mean a few things potentially relevant to your quest:

• There'd be a Perlish lang (NQP -- not quite a small subset of P6) that targets JS (in addition to PIR/Parrot, Java/JVM, and MoarVM).
• There'd be a Perlish toolkit (also called NQP) for easily creating langs, dialects, and compilers that automatically target JS (and NQP's other backends).
• Anything you did to improve JS codegen would be leveraged by all langs/compilers in the NQP ecosystem (NQP itself, P6, phpish, rubyish, yourlang, et al).
