Overview ¶
Package reflectish provides common reflection utilities that extend Go's standard "reflect" library.
It offers:
- IndirectDeep: recursively dereferences pointers until a non-pointer value is reached.
- Interface: the panic-safe form of reflect.Value.Interface (nil for the invalid Value).
- IndirectInterface: deeply dereferences pointers and returns the value as any (nil through nil pointers).
- LengthOf: returns the length of supported types (arrays, slices, maps, strings, channels), along with a boolean indicating support.
Usage:
import "github.com/amberpixels/k1/reflectish"
// Deeply dereference pointers
val := reflect.ValueOf(&&myStruct)
root := reflectish.IndirectDeep(val)
// Get length of a slice, map, etc.
length, ok := reflectish.LengthOf([]int{1,2,3})
if ok {
fmt.Println("Length:", length)
}
Package reflectish is intended as a lightweight helper for reflection-based operations.
Package reflectish contains helpers that extends standard reflect library

Functions ¶
func IndirectDeep ¶
IndirectDeep does reflect.Indirect deeply.
func IndirectInterface ¶ added in v0.1.6
IndirectInterface deeply dereferences pointers and returns the underlying value as any, yielding nil when it dereferences through a nil pointer. It is shorthand for Interface(IndirectDeep(v)).
func Interface ¶ added in v0.1.5
Interface is the panic-safe equivalent of reflect.Value.Interface.
reflect.Value.Interface panics on the zero (invalid) Value — which is exactly what IndirectDeep yields when it dereferences through a nil pointer. Interface returns nil for an invalid Value instead, so the two compose cleanly:
v := reflectish.Interface(reflectish.IndirectDeep(rv)) // nil for nil pointers
