About Code Complexity
This plugin calculates code complexity metric right in the editor and shows the complexity in the hint next to the method/class. It's based on the Cognitive Complexity metric proposed by G. Ann Campbell in Cognitive Complexity - A new way of measuring understandability.
Works with Java, Kotlin, Python, Dart, and Go.
Description from the JetBrains Marketplace listing.
Filled points are observed values; hollow points come from Internet Archive snapshots of the listing page. Dashed segments span periods with no observations — values between points are not interpolated.
Each band is one page of 20. Downloads on a log scale. Placement is projected from downloads, so it can differ from the marketplace's own sort order. Hover a dot to see the listing.
Cumulative download counts come from the public JetBrains Marketplace API. JetBrains reports downloads, not active installs. Ratings are the mean of public votes.
