# or clone the repo and run go run main.go
git clone https://github.com/tompston/dustat.gitnote that the path to the go/bin directory must be in your PATH environment variable
# point to the directory of the Go project (use "." for current directory)
dustat <path-to-dir>
# point to the directory, but do not include certain names
dustat --ignore=MyFuncName,MyStructName <path-to-dir># clone a big example project locally to a tmp dir
git clone [email protected]:ethereum/go-ethereum.git tmp/go-eth
go run main.go ./tmp/go-eth
