I've pulled together a very simple go generate-or that makes sorting
arbitrary slices easier via order functions, removing the need to implement
sort.Interface etc.
go get -u github.com/myitcv/sorter/cmd/sortGen
Simply define an order function on the slice type of interest:
func orderByName(persons []person, i, j int) sorter.Order {
return persons[i].name < persons[j].name
}
then run go generate and a corresponding sort function will have been
generated for you:
// gen_person_sorter.go
func sortByName(vs []person) {
// ...
See the example and rules at the following link for more details:
https://github.com/myitcv/sorter/tree/master/cmd/sortGen
Hopefully some folks will find this useful and a good introduction to go
generate.
Thoughts, feedback etc much appreciated.
