Code Inspections and Intentions
Inspections
The code inspections for custom languages use the same API as all other code inspections, based on the
LocalInspectionTool
class.
The functionality of
LocalInspectionTool
partially duplicates that of
Annotator.
The main differences are:
- supports batch analysis of code (through the Analyze | Inspect Code… action)
- the possibility to turn off the inspection (globally or by suppressing them on various levels)
- ability to configure the inspection options.
If none of that is required and the analysis only needs to run in the active editor, Annotator provides better performance (because of its support for incremental analysis) and more flexibility for highlighting errors.
Example: A simple inspection for Properties language plugin
Intentions
The code intentions for custom languages also use the regular API for intentions.
The intention classes need to implement the
IntentionAction
interface and to be registered using the com.intellij.intentionAction extension point in your plugin.xml.
