c4a32895df conlang 0.3.0: Total grammar overhaul
- 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

d387e4dfd7 interpreter: rewrite interpreter
- 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)

79fda16788 cl 0.0.2: MAJOR ERGONOMIC BOOST
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

ccfddcc09a Conlang: Add range operators
TODO: Limit range operators to at most 2 operands
2023-10-22 18:30:00 -05:00
b5abd2bff1 Lexer rewrite:
- Scan the input string *linearly*, without backtracking
  - Peek at most one character (unicode code-point) ahead
- Store data (unescaped string literals and chars, identifiers, integers, floats) inside Token
  - This unfortunately makes tokens non-Copy
- Refactor Parser to accommodate these changes
  - On the bright side, Parser no longer needs a reference to the text!
- Write a new set of lexer tests
  - TODO: write a new set of token tests using tokendata

Every day, we get closer to parsing `dummy.cl`!

feb5cc5dd0 AST: Refactor binary operations, fix Walk trait
- 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.
