Self-hosting Compiler

[Ronsor]

As the title implies, make wax self-hosting by rewriting it in itself.

Bootstraped? @LingDong- Does wax have string functions? (Sorry for pinging you...)

Hi @Ronsor ,

Thanks for the suggestion!

Yes I've thought about the idea. It's a non-trivial undertaking given the many targets wax supports, and wax itself being a not particularly convenient language to write a compiler in. Of course it's super cool to be self-hosted from a philosophical / "because I can" perspective (indeed what language designer doesn't want their language to be self-hosted :), but it also has somewhat limited practical value from the user's standpoint.

So I'll probably work on it when I have spare time. Let's keep this issue open as a reminder to myself, and maybe for discussing implementation of such a compiler if people are interested/want to contribute.

Hi @Rabios , no worries, and yup, wax has all the basic string operations, please check out https://github.com/LingDong-/wax/blob/main/QUICKSTART.md#strings

Thanks

@LingDong- sounds like a challenge :)

I've made a start with the example program below - not much yet, but it can express a limited source tree and write it back out to output. Next steps:

• transpile output (to javascript initially, as it's easy to implement)
• tokenizer, source parser

Would that be something you'd be interested in taking a pull request for?

Context - I have a software synthesizer project implemented in Golang and with the signal processing and UI code transpilled to javascript, demo here: http://noisefloor.jacob.nz.net/ https://github.com/jacoblister/noisefloor

I've never quite been satisfied with the amount of control I have over the javascript output, so I have been looking for an implementation language which can target at least C (for native builds), and javascript - maybe wax could be it.

Really pleased to have found you project as this has to be the cleanest and smallest Lisp style dialect and implementation I've seen anywhere.

Thanks
