Hi,
With github.com/badgerodon/goreify you can do this:
//go:generate goreify examples/min.Min numeric
// Min finds the minimum value in a slice
func Min(args ...generics.T1) (r generics.T1) {
if len(args) == 0 {
panic("the minimum of nothing is undefined")
}
r = args[0]
for i := 1; i < len(args); i++ {
if generics.Less(r, args[i]) {
r = args[i]
}
}
return r
}
(replacing examples/min with your package name)
This gives:
// MinInt finds the minimum value in a slice
func MinInt(args ...int) (r int) {
if len(args) == 0 {
panic("the minimum of nothing is undefined")
}
r = args[0]
for i := 1; i < len(args); i++ {
if r < args[i] {
r = args[i]
}
}
return r
}
There are other libraries out there that can do the same thing.
