Descriptions
--all
Show all issues for each category
By default, Credo's report is limited to 5 issues per category.
$ mix credo --all
--all-priorities (aliased as --strict)
Show all issues including low priority ones
By default, Credo's report is limited to high priority issues as indicated by the arrows (↑ ↗ → ↘ ↓) next to each issue.
$ mix credo --strict
--checks (aliased as --only)
Only include checks that match the given comma-seperated patterns
# Run only checks where the name matches "readability" or "space" (case-insensitive),
# 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
--checks-with-tag
Only include checks that match the given tag (can be used multiple times)
$ mix credo --checks-with-tag experimental --checks-with-tag controversial
--checks-without-tag
Ignore checks that match the given tag (can be used multiple times)
$ mix credo --checks-without-tag formatter

# e.g. `Credo.Check.Readability.ModuleDoc` or `Credo.Check.Consistency.SpaceAroundOperators`
$ mix credo --enable-disabled-checks readability,space
The patterns are also compiled using Regex.compile/2, which allows for more complex queries:
# Enable all previously disabled checks where the name matches "readability" and "space"
# (case-insensitive), e.g. `Credo.Check.Readability.SpaceAfterCommas`
$ mix credo --enable-disabled-checks readability.+space
# Enable *all* disabled checks by simply using:
$ mix credo --enable-disabled-checks .+
