crafting-interpreters-ts

Follow-up of Robert Nystrom, "Crafting Interpreters", part II, using typescript (and yarn berry for package manager)

How did I set up the environment

yarn init

# somehow yarn set version berry didn't work
yarn set version canary

yarn add typescript @types/node
yarn add -D ts-node

# to use vscode 
yarn dlx @yarnpkg/sdks vscode

# initialize tsconfig.json
yarn tsc --init

I don't feel it necessary, but I added below line into .yarnrc.yml manually:

nodeLinker: pnp

in tsconfig.json:

"lib": ["es6", "dom"]
"rootDir": "src"
"outDir": "dst"
(...)

How to use

After installing dependencies(via yarn), run

yarn direct <filename(optional)>

The Lox interpreter will read the file and execute the code within it. If no filename is provided, the interpreter will enter into prompt mode and execute your input line by line. Ctrl+D to exit.
