CHANGES.md

0.0.13

• Rename Operation::New to :Instantiate to avoid name clashes with New operations in applications.
• Fix Ruby > 2.3.3's Forwardable issue.

0.0.12

• Allow passing tmp options into KW::Option that will be merged with options and then transformed into kw args, but only locally for the step scope (or wherever you do Option.()). The API:

  Option::KW.(proc).(input, options, some: "more", ...)

  Note that KW::Option could be massively sped up with simple optimizations.

0.0.11

• Use Forwardable instead of Uber::Delegates.

0.0.10

• Flow is now Railway.
• Any Right subclass will now be interpreted as success.
• Add fail!, fail_fast!, pass!, and pass_fast!.
• The only semi-public method to modify the pipe is Railway#add
• Removed &, >, < and % "operators" in favor of #add.
• Extremely simplified the macro API. Macros now return a callable step with the interface ->(input, options) and their pipe options, e.g. [ step, name: "my.macro"].

0.0.9

Removing Operation::consider, which is now step. We now have three methods, only.

• step import macro or add step with the & operator, meaning its result is always evaluated and decides about left or right.
• success always adds to right track.
• failure always adds to left track.

This was heavily inspired by a discussion with @dnd, so, thanks! 🍻

0.0.8

• Introduce a new keyword signature for steps:

  step ->(options, params:, **) { options["x"] = params[:id] }

  The same API works for instance methods and Callables.

  Note that the implementation of Option and Skills#to_hash are improveable, but work just fine for now.

0.0.7

• Simplify inheritance by basically removing it.

0.0.6

• Improvements with the pipe DSL.

0.0.5

• _insert provides better API now.

0.0.4

• Don't pass the operation into Result, but the Skill options hash, only.

0.0.3

• Add #inspect(slices).

0.0.2

• Works.
