Usage

Interactive REPL

Run main.py with no arguments to open the interactive shell:

python main.py

Luz Interpreter v1.8.0 - Type 'exit' to terminate
Luz > x = 10
Luz > write(x * 2)
20
Luz > name = "world"
Luz > write($"Hello {name}!")
Hello world!
Luz > exit

The REPL evaluates one statement at a time. Multi-line constructs (functions, classes, loops) are not supported in the REPL — use a file for those.

Run a file

python main.py program.luz

Any .luz file can be executed this way. The interpreter runs the file from top to bottom and exits when it reaches the end.

Run the test suite

python tests/test_suite.py

All built-in tests will run and report pass/fail.
