_generator_sources

A private helper target type used by some target generators.

This tracks their source / sources field so that --changed-since --changed-dependees works properly for generated targets.

Backend: pants.backend.python

`source`

type: str
required

A single file that belongs to this target.

Path is relative to the BUILD file's directory, e.g. source='example.ext'.

`description`

type: str | None
default: None

A human-readable description of the target.

Use pants list --documented :: to see all targets with descriptions.

`tags`

type: Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run pants --tag='integration_test' test :: to only run on targets with that tag.
