Optionally, add this to your ~/.vimrc to automatically run golint on :w
autocmd BufWritePost,FileWritePost *.go execute 'Lint' | cwindow
+
+
+Emacs
+-----
+Add this to your .emacs file:
+ (add-to-list 'load-path (concat (getenv "GOPATH") "/src/github.com/golang/lint/misc/emacs"))
+ (require 'golint)
+If you have multiple entries in your GOPATH, replace $GOPATH with the right value.
+
+Running M-x golint will run golint on the current file.
