We have 6 non-empty presets to choose from to make your code look totally gorgeous. Our recommended preset is enabled by default on all repos. We also have an additional preset, none, which enables no fixers.
By default, "risky" heuristic fixers are disabled. When risky mode is enabled, all risky and non-risky fixers provided by a preset will be enabled, and when risky mode is disabled, only the non-risky fixers will be enabled. For example, when enabling the psr12 preset, with risky: false or without specifying the risky mode, the no_trailing_whitespace_in_string, no_unreachable_default_argument_value, and psr4 fixers will not be enabled by the preset.
