How do you recommend parsing Ruby to Ruby?

Question

ruby

I want to parse a language like Ruby/JavaScript, where ";" at the end of the statement can be omitted if the line immediately ends. At the same time, it would be very undesirable to place
spaces in each place of the rules where they (spaces) may occur (Citrus).
Efficiency of code execution is not important; rather, speed, simplicity, and elegance are required when writing rules and event handlers.

Answer 1

first links in google:
lex - raa.ruby-lang.org/project/ruby-lex/
yacc - i.loveruby.net/en/projects/racc/ bnf
grammar - www.cse.buffalo.edu/ ~regan /cse305/RubyBNF.pdf
and I recommend reading this book first - en.wikipedia.org/wiki/%D0%9A%D0%BE%D0%BC%D0%BF%D0%B8%D0%BB%D1% 8F%D1%82%D0%BE%D1%80%D1%8B :_%D0%BF%D1%80%D0%B8%D0%BD%D1%86%D0%B8%D0%BF%D1% 8B,_%D1%82%D0%B5%D1%85%D0%BD%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D0%B8_%D0%B8_%D0% B8%D0%BD%D1%81%D1%82%D1%80%D1%83%D0%BC%D0%B5%D0%BD%D1%82%D1%8B

Answer 2

What do you need?
You were given a generator of lexical analyzers, a generator of parsers, a grammar that they need to feed and a book that says how, what and why to do.

Answer 3

One friend has already implemented a parser - https://github.com/whitequark/parser, produces ast
