Gocyclo calculates cyclomatic complexities of functions in Go source code.
The cognitive complexity of a function is calculated according to the following rules (like Sonar):
1 is the base complexity of a function
+1 for each 'if', 'for', 'case', '&&' or '||' inside 'if', 'for'
+1 for nested 'if', 'for', 'case', 'func'
Note: this is the fork from fzipp/gocyclo but it caculate nested complexity as well.
To install, run
$ go get github.com/yfwz100/gocyclo
and put the resulting binary in one of your PATH directories if
$GOPATH/bin isn't already in your PATH.
Usage:
$ gocyclo [<flag> ...] <Go file or directory> ...
Examples:
$ gocyclo .
$ gocyclo main.go
$ gocyclo -top 10 src/
$ gocyclo -over 25 docker
$ gocyclo -avg .
The output fields for each line are:
<complexity> <package> <function> <file:row:column>
