functional-gml

Functional stuff for Game Maker Studio 2.3. Early work in progress. This is an attempt to add functional pipes to game maker, abstract iterators and common functional programming functions for all data structures (reduce, map, filter, for_each, flatten, group_by etc).

Also, reactive streams are planned.

Example pipe

var _map = pipe(buffer_create(64, buffer_fixed, 4), FType.Buffer)
  .map(function(v, i){ return i; })
  .extend(new Iterator([1, 2, 3], FType.Array))
  .map_type(function(v){ return {id: v, name: "name"}; }, FType.Array)
  .filter(function(v){ return v.id%3 != 0; })
  .group_by(function(v){ return v.id%2 == 0; });
