ttalk-lang

A small but working language created for a Spotify tech talk, intended to demonstrate compiler design principles.

Getting Started

npm i to install dependencies

npm run build to compile the typescript to javascript

You can run the ttalk CLI:

You can also run ./ttalk -h to list all available commands.

These are the core files, in execution order:

src/index.ts: The entrypoint for the CLI, handles the commands
src/lexer.ts: The lexer - chunks the source into Tokens
src/parser.ts: The parser - transforms the Token list into an AST
- src/ast.ts: Typescript helper file containing AST Node types
src/compiler.ts / src/compiler-js.ts: The compiler - generates either bytecode or javascript
- src/visitor/ts: Typescript helper file defining the Visitor interface (helping enforce the Visitor Pattern)
src/vm.ts: The Virtual Machine capable of running the bytecode generated by src/compiler.ts
