This is a simple interpreter for the Scheme programming language written in Scala. It supports basic Scheme features such as arithmetic operations, conditionals, and function definitions.
The interpreter also supports the following command-line options:
--i: Launches the REPL (Read-Evaluate-Print Loop), which allows you to interactively enter and evaluate Scheme expressions.--file <filename>: Reads the Scheme program from the specified file and executes it.
For example, to launch the REPL, run:
schemezip --i
To execute a Scheme program from a file named myprogram.scm, run:
schemezip --file myprogram.scm --i
The interpreter supports the following Scheme R5RS features:
| Feature | Supported |
|---|---|
| define | ✅ |
| lambda | ✅ |
| arithmetic | ✅ |
| lists | ✅ |
| vectors | ✅ |
| ports | ✅ |
| macros | ❌ |

The interpreter comes with a suite of tests to ensure that it works correctly. To run the tests, run the Test class:
