splint is a little Go application to analyze Go source files. It finds any functions that are too long or have too many parameters or results.

These are typical signs that a function is doing too much. We find splint to be a helpful tool for detecting potential problem areas in our code, areas that should be refactored. We tolerate long functions and functions with long parameter/result lists when they are needed, but generally try to keep them short.

Use go install:

go install stathat.com/c/splint
