prednote

[ bsd3, data, library ] [ Propose Tags ]

Build and evaluate trees of predicates. For example, you might build a predicate of the type Int -> Bool. You do this by assembling several predicates into a tree. You can then verbosely evaluate this tree, showing why a particular result is reached.

prednote also provides modules to test several subjects against a given predicate, and to parse infix or RPN expressions into a tree of predicates.

tests are packaged separately in the prednote-tests package.

Readme for prednote-0.26.0.2

[back to package description]

prednote

prednote helps you build a tree of predicates that you can apply to a list of items. It was written for Penny:

http://www.github.com/massysett/penny

but I also find it useful for dapi:

http://www.github.com/massysett/dapi

and so you might find it useful too.

prednote is on Github:

http://www.github.com/massysett/prednote

and Hackage:
