----------------------------------
Summary: [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: Sub-task
Components: sdk-go
Reporter: Robert Burke
Assignee: Henning Rohde
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").
