cl-token:
- Minimize data redundancy by consolidating TokenKind::Literal; TokenData::{String, Identifier}
- Rename Op to Punct
cl-ast:
- Remove ExprKind::{Member, Call} in favor of making them
'binary' operators
- Consolidate boxes (TODO: consolidate more boxes)
- Remove repetition vecs in favor of boxes (this may come with performance tradeoffs!)
cl-lexer:
- Reflect changes from cl-token
cl-interpret, cl-repl/src/examples:
- Reflect changes from cl-ast
cl-parser:
- Switch to Pratt parsing for expressions
- TODO: Code cleanup
- TODO: Use total ordering for Precedence instead of binding powers (that's what the binding powers are there for anyway)
- Switch functional parsers to take Punct instead of TokenKind
- It's not like we need a `for`-separated list
- Remove `binary` macro. No longer needed with precedence climbing.
- Repurpose `operator` macro to produce both the operator and the respective Precedence
- Remove several of the smaller parser functions, since they've been consolidated into the larger `exprkind`
My editor's performance was tanking because of macro interpreter::builtins::builtin!
Temporary solution: move the interpreter into a separate crate
If I intended to keep the interpreter around, in the long-term, it might be an idea to make a proc-macro for builtin expansion.
However, the only reason I need the macros is because the interpreter's dynamic typing implementation is so half-baked. After I bang out the new type checker/inference engine, I'll have to rewrite the entire interpreter anyway!
- 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
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
