lintis for code that can be easily incorrect or is suspicious (ifmissing a branch, a threading macro with a single element, etc).metricsis about properties of code that can be measured, such as length of functions.namingis about the names given to defining forms (defn,defrecord, etc) when they don't adhere to Clojure community idioms or style.performanceis for code that has faster alternatives at the cost of larger or more unwieldy code ((assoc m :k1 v1 :k2 v2)vs(-> m (assoc :k1 v1) (assoc :k2 v2)), etc). These are disabled by default as they are more contentious than the rest.styleis for code that doesn't adhere to Clojure community idioms or style, especially when there are existing alternatives ((when (not ...))vs(when-not ...), etc).
Note: There is also dev used to lint Splint's own codebase that aren't meant to be public. These are stored in the dev/ folder.
