That's essentially what the go generate command is about - a command run by go generate has access to parsed syntax trees, type information and anything else it likes (bar actual compiler internals), and can generate whatever code it likes. For example, I think it's pretty clear that what the Wire project does (see https://github.com/google/wire/blob/master/docs/guide.md) is metaprogramming, to some degree or other. cheers, rog. > -- > You received this message because you are subscribed to the Google Groups > "golang-nuts" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to golang-nuts+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
