Code Inspection: Empty branch in alternation

Last modified: 13 May 2022

Configure inspections: Settings | Editor | Inspections

Show intention actions: AltEnter

Reports empty branches in a RegExp alternation. An empty branch will only match the empty string, and in most cases that is not what is desired. This inspection will not report a single empty branch at the start or the end of an alternation.

Example:

(alpha||bravo)

After the quick-fix is applied:

(alpha|bravo)

New in 2017.2
