--checks (aliased as --only)

# e.g. `Credo.Check.Readability.ModuleDoc` or `Credo.Check.Consistency.SpaceAroundOperators`
$ mix credo --only readability,space

The patterns are also compiled using Regex.compile/2, which allows for more complex queries:

# Run only checks where the name matches "readability" and "space"
# (case-insensitive), e.g. `Credo.Check.Readability.SpaceAfterCommas`
$ mix credo --only readability.+space
