LAttempt1 is my first attempt at implementing a functioning interpreter for a lisp language. It is very rudimentary, but it served well for my learning purposes. The language design was inspired by clojure in certain topics, but severally limited for simplicity purposes.

An example program can be found inside sample.txt

• Pure s-expression syntax (no []s or {}s)
• No ' or ` quoting
• No string literals
• Lexical Scoping
• Lambdas
• Macros
• Naive Garbage Collection

value: literal | list

literal: symbol | number

list: '(' opt_values ')'

opt_values: values | ''

values: value values | value

Only non-negative integer literals are supported.

To build the project, use zig build, which installs the executable at zig-out/bin.

You can run the project with zig build run, or with the executable.

The lattempt1 executable starts a rudimentary repl for the language. the file sample.txt provides some code samples which can be executed with

./lattempt1 < ../sample.txt

using a POSIX shell.
