JSON-RPC pipeline batches

Typical RPC implementation

Say we want to implement an RPC service for basic maths operations. For example, let's calculate the value of ln(e^2). This calculation has several steps in our maths API:

  1. Get the value of e
  2. Square e

Rendering a recursive tree of items with mercury

// Mercury is a 'truly modular frontend framework'. This helpful import gets
// us a lot of top-level symbols from submodules it re-exports.
var hg = require('mercury');
// Like this one - h is a short constructor for HTML elements.

crabmusket / Cheryl.hs

A translation of Norvig's solution to the Cheryl's Birthday problem from Python to Haskell. Original:
View Cheryl.hs
-- A list of possible dates Cheryl's birthday might be on.
possibilities = [(May, 15), (May, 16), (May, 19),
(June, 17), (June, 18),
(July, 14), (July, 16),
(August, 14), (August, 15), (August, 17)]
-- We say we know the actual date when the list of possibilities is singular.
know ps = length ps == 1
-- Telling someone the month or day will reduce the possibilities.
