# Lamb

A (very WIP) lambda expression evaluator and debugger.

I'd like to build the following:

- [X] parsing with parsec
- [X] alpha/beta reduction to beta normal
- [ ] substitutions for known abstractions (numbers can be written and are displayed as numbers rather than lambda terms)
  - [ ] replace known terms in input
  - [X] replace known terms in output
  - [ ] support detection and replacement for generic church numerals (not just 1 and 0 (false))
- [ ] persisted variables
- [ ] display all steps in alpha/beta reductions until beta normal form is reached
- [ ] online web-based lambda playground
