Overview¶

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

$ go install golang.org/x/tools/cmd/goimports@latest

In addition to fixing imports, goimports also formatsyour code in the same style as gofmt so it can be usedas a replacement for your editor's gofmt-on-save hook.

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

Then in your .emacs file:

(setq gofmt-command "goimports")(add-hook 'before-save-hook 'gofmt-before-save)

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

For GoSublime, follow the steps described here:

For other editors, you probably know what to do.

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