The popular Railway/Fasttrack DSL for building activities.
This gem allows creating activities by leveraging a handy DSL. Built-in are the strategies Path, the popular Railway and FastTrack. The latter is used for Trailblazer::Operation.
Note that you don't need to use the DSL. You can simply create a InIm structure yourself, or use our online editor.
Full documentation can be found here: trailblazer.to/2.1/#dsl-linear
Normalizers are itself linear activities (or "pipelines") that compute all options necessary for DSL.insert_task.
For example, FailFast.normalizer will process your options such as fast_track: true and add necessary connections and outputs.
The different "step types" (think of step, fail, and pass) are again implemented as different normalizers that "inherit" generic steps.
:sequence_insert
:connections are callables to find the connecting tasks
