blue-lang-syntax 0.0.21

blue's surface syntax.

Blue is a general-purpose language whose surface is Ruby/Elixir-shaped and whose program is a tatara-lisp value. This crate is the join: it lexes blue source and parses it directly into tatara_lisp::Sexp.

There is deliberately no private blue AST in between. Tenet 1 of theory/BLUE.md is that blue source parses to tatara-lisp, and an intermediate tree would make homoiconicity a conversion step rather than an identity — the difference between blue's macro story working and merely being asserted.

use blue_lang_syntax::parse_expr;
let form = parse_expr("user.greet(1)").unwrap();
assert_eq!(form.to_string(), "(greet user 1)");
