ConfigAware

Interface which is implemented by each Rule class to provide utility functions to retrieve specific or generic properties from the underlying detekt configuration file.

Be aware that there are three config levels by default:

the top level config layer specifies rule sets and detekt engine properties
the rule set level specifies properties concerning the whole rule set and rules
the rule level provides additional properties which are used to configure rules

This interface operates on the rule set level as the rule set config is passed to each rule in the #RuleSetProvider interface. This is due the fact that users create the rule set and all rules upfront and letting them 'sub config' the rule set config would be error-prone.

Inheritors

Rule

Properties

active

open val active: Boolean

Is this rule specified as active in configuration? If a rule is not specified in the underlying configuration, we assume it should not be run.

autoCorrect

open val autoCorrect: Boolean

Does this rule have auto correct specified in configuration? For auto correction to work the rule set itself enable it.

parentPath

open val parentPath: String?

Keeps track of which key was taken to subConfig this configuration. Sub-sequential calls to subConfig are tracked with '>' as a separator.

ruleId

abstract val ruleId: RuleId

Id which is used to retrieve the sub config for the rule implementing this interface.

ruleSetConfig

abstract val ruleSetConfig: Config

Wrapped configuration of the ruleSet this rule is in. Use valueOrDefault function to retrieve properties specified for the rule implementing this interface instead. Only use this property directly if you need a specific rule set property.

Functions

createPathFilters

fun Config.createPathFilters(): PathFilters?

subConfig

open override fun subConfig(key: String): Config

Tries to retrieve part of the configuration based on given key.

valueOrDefault

open override fun <T : Any> valueOrDefault(key: String, default: T): T

Retrieves a sub configuration or value based on given key. If configuration property cannot be found the specified default value is returned.

valueOrDefaultCommaSeparated

fun Config.valueOrDefaultCommaSeparated(key: String, default: List<String>): List<String>

valueOrNull

open override fun <T : Any> valueOrNull(key: String): T?

Retrieves a sub configuration or value based on given key. If the configuration property cannot be found, null is returned.
