godep-aware goimports and more

goimports

#!/bin/sh

# for use with emacs/vim/etc as goimports and goflymake
#
# I use it with config like:
#
# (setenv "GOPATH" (expand-file-name "~/Projects/go"))
# (setenv "PATH" "~/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:~/Projects/go/bin:/usr/local/go/bin")
# (setq exec-path (append exec-path (list (expand-file-name "~/Projects/go/bin") "/usr/local/go/bin")))
#
# and put this script as `goimports` in ~/bin + symlink `goflymake` to it
# with the real `goimports` and `goflymake` in $GOPATH/bin
