Lox.jl

Crafting Interpreters, but in Julia.

interpreter

The first half of the book (tree-walk interpreter).

Run with

cd interpreter
julia --project=. interpreter.jl [LOX_FILE]

where LOX_FILE is a file containing Lox code, or leave it empty to enter the REPL.

Some sample Lox programmes are given in the loxprogs folder.

From inside Julia

To mitigate the TTFX on loading the REPL, you can also run

using LoxInterpreter; run_prompt()

Ctrl-D will return you to the Julia REPL; if you have Revise.jl loaded you can call run_prompt() again and your changes will be reflected.

To run a file from the Julia REPL:

using LoxInterpreter; run_file("path/to/lox_file.lox")
