Hi, Is it possible to merge any JS mode that have regular expressions and integrate it with scheme mode? How hard it would be? I have Lisp written in JavaScript https://jcubic.github.io/lips/ and I would like to have proper Emacs Mode for my language. The language is based on scheme (almost 100% compatibile with R5RS and I'm wokring on R7RS) but have few extensions like literal regular expressions that are almost the same as one in JavaScript except it can't have space after first / to prevent matching expressions like (/ (* 10 (/ 10 2)) I thikng that I will disable completly spaces in regexes to prevent any ambiguity. I also have object literals that are create created using syntax extensions I've created for my language: &(:foo 10 :bar 20) create JS object & is the same as ` or ' in scheme it map to macro call. I have some experience with Emacs Lisp, but I didn't read much code and I don't have much experience in creating Emacs modes, even that I have created one that is on GitHub (for JS & PHP code coverage that I was not able to merge with coverage.el because original author only care about Ruby). Could anyone give me some tips how should I go about and create such mode? Where I should look for regexes in JS mode and how should go about and adding them to scheme mode?
