My [Own|Outstanding|Odd|Overrated|Offbeat|Obnoxious|Otherworldly]{2,} Lisp
Moo is a simple Lisp implemented in Python. The implementation is probably not waterproof — the Python is bound to shine throgh occasionally and I might have gotten something wrong. Please let me know, or even better send a pull request, if you find something amiss!
Oh, and please don't do anything silly like using Moo for production code, or anything like that. This is obviously just a toy language.
To run the REPL (see an example here):
./moo
To interpret a file:
./moo example.moo
Short answer: For fun.
Longer answer: Implementing your own programming language is a very educational experience. I wrote Moo Lisp both to better understand how programming languages works, and to test my understanding of some concepts I already knew. Hopefully, the implementation of Moo could also serve as an example to others getting started learning about languages.
The test suite require nosetests to be installed. If you want to run the tests yourself, install dependencies like this:
pip install -r requirements.txt
Then, run the tests
