Yes, I have seen it. Your approach is different by just sorting a list of filenames. The orginal intent is to sort files by extension into different buckets.
Your use of filepath.Ext() is quit clever. Haven't thought of that.
var m = make(map[string][]string)
for _, file := range dir {
if !file.IsDir() {
fileName := file.Name()
ext := filepath.Ext(fileName)
m[ext] = append(m[ext], fileName)
}
}
for ext := range m { sort.Strings(m[ext]) }
Thanks for the replies! filepath.Ext()! Didn't occur to me to try that. It goes to show that the standard library really is pretty complete.
Dirk, I like the for ext := range m { sort.Strings(m[ext]) } solution then I wouldn't need to have a separate sort in each "print" function, it's much clearer that way.

This would make the example even shorter:
