Common

• all
• derive
• prebuild
• template
• dev

Lex

• regexlex : crates/lex_regex

Parse

• lr0 : crates/parse_lr_lr0

// RegexLex(lex) + LR1(parse) + SExp(ir)
copager = { ..., features = ["derive", "regexlex", "lr1", "sexp"] }

// RegexLex(lex) + LALR1(parse) + Void(ir)
copager = { ..., features = ["derive", "regexlex", "lalr1", "void"] }
