About

Implementation of the Lox language from Crafting Interpreters.

Generate Types

To regenerate the expr/ and stmt/ classes, run node ./tool/generateExpressions.cjs and node ./tool/generateStatements.cjs. This will overwrite all files in the two folders.

Setup

Build the project with make build

To start the REPL go to ./bin and execute node index.js. A script can be executed with node index.js <path-to-file>

Furthermore the AstPrinter from the book was enhanced and converted to a Scheme Transpiler, which generates executable scheme code. To transpile a script call node index.js --scheme <path-to-file>.

Known Problems

• For the scheme transpiler, classes can only be defined on the top level.
