--------------------------------
Issue Type: Improvement (was: Sub-task)
Parent: (was: BEAM-3826)
> [Go-SDK] Add light example output helpers for documentation
> -----------------------------------------------------------
>
> Key: BEAM-4156
> URL: https://issues.apache.org/jira/browse/BEAM-4156
> Project: Beam
> Issue Type: Improvement
> Components: sdk-go
> Reporter: Robert Burke
> Assignee: Robert Burke
> Priority: Major
>
> Go has facilities to have "live" examples that run as part of the test suite,
> and are incorporated directly into the package documentation. These can also
> sanity check that text sent to STDOUT matches an expected set of lines.
> This task has two desired components:
> * A way to run the direct runner with significantly fewer lines of debugging
> output.
> * A light type checker that outputs PCollection types.
> These would permit more expressive examples, and turn examples into tests.
> This also avoids oddities such as unused variables that need to be assigned
> to _ to satisfy the Go Compiler. ("_ = foo_unused").
