Searching idea.log

When debugging IntelliJ code, search idea.log using these patterns:

Log Levels:

FINE = debug level (from LOG.debug { })
INFO = info level (from LOG.info())

Category Format: #<abbreviated.package.path>.<ClassName>

Example: com.intellij.openapi.wm.impl.status.IdeStatusBarImpl → #c.i.o.w.i.s.IdeStatusBarImpl

Search Examples:

# Debug logs from IdeStatusBarImpl
grep "FINE - #c.i.o.w.i.s.IdeStatusBarImpl" idea.log

# Info logs from IdeStatusBarImpl
grep "INFO - #c.i.o.w.i.s.IdeStatusBarImpl" idea.log

# All logs from a class
grep "#c.i.o.w.i.s.IdeStatusBarImpl" idea.log

End-to-End Behavior

When fixing issues where a user-facing entry point (script, command, API) doesn't behave as expected:

Trace the full execution chain from entry point to actual executor before making changes
Identify all layers that handle the relevant behavior - each layer may swallow, transform, or ignore it
Verify the fix at the entry point the user actually invokes, not just at the layer you modified
Add debugging output if still unsure - add to all layers to trace the issue
