In Golang, we often import external packages from third party sources and ended with import statement that look like this example : import ( "bytes" "github.com/somelongname/verylongnamepackage" "fmt" "github.com/disintegration/imaging" "image" ) now, if you don't want to type in the verylongnamepackage each time you want to call a function in it. You can shorten the verylongnamepackage. just change to import ( "bytes" vlongname "github.com/somelongname/verylongnamepackage" "fmt" IG "github.com/disintegration/imaging" "image" ) and then instead of verylongnamepackage.SomeFunction(), you just invoke it by vlongname.SomeFunction().
