Re: [go-nuts] Is it possible to unmarshall Json by selecting the struct from a field in the Json?

Thanks for the all the responses but I was after a more dynamic solution where you don't need to 'register' the types or select them using a switch but that it just works. For example, to support new types (like the PHP code) I was hoping you could just add the structs and no more changes to

[go-nuts] Re: Is it possible to unmarshall Json by selecting the struct from a field in the Json?

Thanks. I read that blog post earlier and presents two different ways of handling this. Each maintains a list of switch cases and constants respectively so still not entirely dynamic. I'll probably just go with a switch then. On Wednesday, 28 March 2018 13:25:47 UTC+1, Andrei Tudor Călin

[go-nuts] Re: casting slice of rune to string picks up extra characters for some inputs

Go strings are UTF-8 encoded as others have mentioned. This means that each human readable character in the string is really a cluster of one or more runes. Some characters are made up of one rune, some are made up of many. Some runes combine with others to create different characters. Also,

[go-nuts] Re: Ignoring UTF-8 BOM when decoding JSON

This looks like a compounded error. First, Json should never have a BOM encoded within it. Second, it seems like the Go Json decoder doesn't account for the BOM if it is mistakenly encoded. Both are mentioned in the Json RFC: https://tools.ietf.org/html/rfc7159#section-8.1 On Friday, 23
