hnock
A Nock interpreter.
Install
Use a simple
stack install
to build the hnock binary and get it moved somewhere on your PATH. If you
just want to build the binary, you can use stack build.
Usage
From bash, simply pipe Nock expressions into the hnock executable:
$ echo '*[[[4 5] [6 14 15]] [0 7]]' | hnock
[14 15]
For playing around in GHCi, import the Nock library and use hnock to parse
and evaluate Nock expressions:
*Nock> hnock "*[[[4 5] [6 14 15]] [0 7]]"
[14 15]
To evaluate raw nock Nouns, i.e. to compute nock(a) for some noun a, use
the nock function:
*Nock> let expression = hnock "[[[4 5] [6 14 15]] [0 7]]"
*Nock> expression
[[[4 5] [6 [14 15]]] [0 7]]
*Nock> nock expression
[14 15]
Testing
Use a simple stack test to run the test suite.
