Description

Command goimports updates your Go import lines, adding missing ones and removing unreferenced ones.

$ go get golang.org/x/tools/cmd/goimports

It's a drop-in replacement for your editor's gofmt-on-save hook. It has the same command-line interface as gofmt and formats your code in the same way.

For emacs, make sure you have the latest go-mode.el:

https://github.com/dominikh/go-mode.el

Then in your .emacs file:

(setq gofmt-command "goimports")
(add-to-list 'load-path "/home/you/somewhere/emacs/")
(require 'go-mode-load)
(add-hook 'before-save-hook 'gofmt-before-save)

For vim, set "gofmt_command" to "goimports":

etc

For GoSublime, follow the steps described here:

For other editors, you probably know what to do.

To exclude directories in your $GOPATH from being scanned for Go files, goimports respects a configuration file at $GOPATH/src/.goimportsignore which may contain blank lines, comment lines (beginning with '#'), or lines naming a directory relative to the configuration file to ignore when scanning. No globbing or regex patterns are allowed. Use the "-v" verbose flag to verify it's working and see what goimports is doing.
