- Rewrote the grammar
- Rewrote the AST
- Rewrote the Parser
- Removed pretty printer (now handled by ast::ast_impl::Pretty, a Writer wrapper)
- Added items, and new keywords to go with them
- Syntax is ~maybe temporary, based on Rust syntax
- Remove interpreter struct
- Replace with `Interpret` trait
- This separates concerns dramatically! Yay!
- Implement block scoping via `Frame` abstraction
- TODO: is this the right abstraction?
- TODO: Modules??
- TODO: What environment should be passed into a function call?
ast:
- rename Name.name to Name.symbol (name.name.name.name.name.name.name is very readable, yes yes)
Broke frontend into its own library, "cl-frontend"
- Frontend is pretty :D
- Included sample fibonacci implementation
Deprecated conlang::ast::Visitor in favor of bespoke traits
- Rust traits are super cool.
- The Interpreter is currently undergoing a major rewrite
Added preliminary type-path support to the parser
- Currently incomplete: type paths must end in Never..?
Pretty printer is now even prettier
- conlang::ast now exports all relevant AST nodes, since there are no namespace collisions any more
- Unified math operations into a single self-referential enum
- Walk now visits the children of a node, rather than the node itself
- The old behavior was super confusing, and led to numerous stack overflows.
