Based on https://github.com/eugeii/goimports, this is another fork of goimports (golang.org/x/tools/cmd/goimports) that allows to skip the walk through all directories included in $(GOPATH)/.goignore.

It basically makes goimports fast again.

go get -u github.com/maraino/goofimports

A script generate.sh is included which can generate an optimal .goignore file (all directories that do not contain .go files in their subdirectories). To use it to generate your .goignore file:

sh "$GOPATH/src/github.com/maraino/goofimports/generate.sh" | tee "$GOPATH/.goignore"
