Pattern: Unused variable
Issue: -
Checks for variables that are never referenced. An assignment to the variable is not considered a reference.
The rule has a property named ignoreVariableNames, which can be set to ignore some variable names. For instance, to ignore fields named 'unused', set the property to 'unused'.
| Property | Description | Default Value |
|---|---|---|
| ignoreVariableNames | Specifies one or more (comma-separated) variable names that should be ignored (i.e., that should not cause a rule violation). The names may optionally contain wildcards (*,?). | null |
Known limitations:
- Incorrectly considers a variable referenced if another variable with the same name is referenced elsewhere (in another scope/block).
