Introduction

Adapton.python is an Python library for self-adjusting computation.

Quick-start

1. Run Adapton.python unit tests:

   % make test
   

2. Start an Python REPL with Adapton.python in PYTHONPATH:

   % make repl

   >>> from Adapton.Lazy import *
   >>> x = Lazy(1)
   >>> y = Lazy(2)
   >>> z = Lazy(lambda: x.force() + y.force())
   >>> z.force()
   3
   >>> x.update(5)
   >>> z.force()
   7
   >>> y.update(4)
   >>> z.force()
   9
   

3. Generate a visualization of Adapton.python in operation:

   % make visualize-listops
   # open ListOps.visual/visualize.html in Safari (doesn't work in other browsers)
