rules#

Individual rules can be disabled via the --exclude flag

squawk --exclude=adding-field-with-default,disallowed-unique-constraint example.sql

`.squawk.toml` configuration file#

Rules can be disabled with a configuration file.

By default, Squawk will traverse up from the current directory to find a .squawk.toml configuration file. You may specify a custom path with the -c or --config flag.

squawk --config=~/.squawk.toml example.sql

The --exclude and --pg-version flags will always be prioritized over the configuration file.

example `.squawk.toml` configurations#

excluding rules#

# .squawk.toml
excluded_rules = [
    "require-concurrent-index-creation",
    "require-concurrent-index-deletion",
]

specifying postgres version#

# .squawk.toml
pg_version = "11.0"

specifying whether SQL files will be wrapped in a transaction#

# .squawk.toml
assume_in_transaction = true

using all options#

# .squawk.toml
pg_version = "11.0"
excluded_rules = [
    "require-concurrent-index-creation",
    "require-concurrent-index-deletion",
]
assume_in_transaction = true

See the Squawk website for documentation on each rule with examples and reasoning.
