maker

The basic idea

It is always better to separate the 'what' from the 'how'. It is better to have dependency as a value provided by the 'system' (in transparent way) rather than as a result of another function call.

This is an experiment to see what happens if we structure our system as goals (values/things/nouns) and dependencies between them.

What is the problem again?

Watch this. Different domain and a different solution, but he is speaking about the same issue in the next 3 minutes.

maker is

• still in alpha!
  • pls help to improve and give feedback
• influenced by dependency injection frameworks, goal oriented programming, declarative programming, build tools, data flow programming, value-level programming, transducers

Features

• dependency tracking by looking for functions based on the names of the parameters
• efficient support for polymorphism (defmulticase, defcasegoal)
• parametric goal with defgoalfn
• asynchronous goals, parallel execution,
• spec for goals,
• works across namespaces

Usage, learn

[maker "3.0.0"]

To learn check out and play with the didactic tests.

See how to add spec to your goals: spec_test.clj

Alternative

• From the amazing plumatic group: plumbing
