How to convert JS into eslisp syntax? #26

Closed reverofevil closed 8 years ago

reverofevil commented 8 years ago

I would like to reimplement some infrastructure like browserify over eslisp syntax, because it's common for such utilities to have imperative API that is very hard to extend, and I don't trust their conversion methods. But this would require not only JS pretty printer, but a JS parser too.

Is there already such an utility?

There's no JS → eslisp decompiler, if that's what you mean.

It might be possible to write a decompiler, using esprima to parse JavaScript into an estree object and writing logic that does the inverse of the built-in macros, and producing eslisp code. However, it could only easily produce "core" eslisp code that uses the built-in macros (which match 1-to-1 with JavaScript). Anything else would take fairly substantial work on pattern matching.

I'm unsure what you mean by the browserify comparison. Could you elaborate?

Closing this for now, because I'm unclear on what you meant.

This sounded interesting though—if you could clarify, I'll reopen.
