ilang

Toy programming language to experiment with writing an interpreter.

Next maybe in this repo, maybe in new ones:

• LSP server
• treesitter integration
• Static types
• Compiler? maybe
• Garbage collection

Setup

Build generated code. Note: must have antlr installed and aliased to antlr4

./build.sh

Run tests

go test -v ./...

Run interpreter

go run .

# or
./build/ilang

# debug mode
./build/ilang -d

Interpreter TODO

• WrappedValue type
  • has map children with child bindings
  • implemented by all primitives
• update current to use wrapped value
• parse and impl array and map
• parse and impl reassignments
• parse and impl return
• implement algebra, conds, boolean alg
• implement control flow
• refactor value types
• function definition type
• implement function call
• command line with file and interactive mode
• map/array indexing
• handle early returns
• try/catch/throw
• custom error stat https://stackoverflow.com/questions/18132078/handling-errors-in-antlr4
• imports/exports
• standard functions on wrapped value
• simple package manager (un-versioned git repo curls? maybe)
