- Note: This adds a dependency on Crossterm, to set the terminal into raw mode. This could be eliminated by linking the libraries Crossterm uses directly... Or I could embrace Crossterm, and use it for all escape sequences in the terminal, instead of assuming DEC VT500 compatibility.
Conlang: Expression-Oriented Programming Language
This project began out of a desire to merge Rust-style control flow expressions with Python's fun for-else/while-else syntax. I fully intend to devote my spare time to conlang for the forseeable future, and I livestream development on Twitch for one Friday each month.
Immediate Goals:
- Decide on a minimal set of keywords and operators to support
- Lex an entire Rust source file (minus generics, paths, and lifetimes)
- Write expression grammar
- Write AST for expression grammar
- Write parser for AST
- Create tests for parser (and AST)
- Parse
dummy.clinto a valid AST - Pretty printer, for debugging
- Create minimal statement grammar
- Variable definition statements
- Function definition statements
Short Goals:
forloops andwhileloops can be used on the trailing side of an assignment- Tree-walk interpreter for prototyping and debugging
- Data structures and sum-type enums
- Expression type-checker
- Trait/Interface system
- Three-address bytecode VM for standard library development
Long Goals:
- Minimize the number of kinds of statements
- Compile to LLVM IR
- Create a standard library for the language, with Rust-like abstractions.
- Port the compiler to Conlang
