go-clap VS JSON-to-Go

If you are interested, check it out on https://github.com/fred1268/go-clap

Cobra has lots of features, but is really complex and intrusive, especially for a newcomer. I would advise you to have a look at clap (https://github.com/fred1268/go-clap) which is very easy to use and absolutely non intrusive. All you need to do is to create a struct containing the fields you want to retrieve from the command line, and annotate it with standard Go tags.

For some in depth examples on how to use reflection in Go and transform types into others, I would suggest you to have a look at clap, the Command Line Argument Parser, and more specifically this file.

That site likely uses Matt's lib for that functionality: https://github.com/mholt/json-to-go

https://mholt.github.io/json-to-go/ is a nice tool for generating a struct definition to fit some sample JSON.

json-to-go is your friend.

JSON to struct. I use this about 100 times a day, no joke.

Do your best to get static types on everything. Play a game with yourself where interface{} is banned and try to do your work. One of the most common sources of such loosely-typed values in JSON, so I'll point out this automatic struct generator for instance. If you have questions about a specific place you don't see how to avoid interface, feel free to ask. Every once in a while I do have to reach for something like this, but it should be rare.

But given we know ChatGPT can't accurately generate structs from even moderately complex json objects why bother doing all of that legwork of verifying and chiding chatgpt, when you can just drop it into a tool like https://mholt.github.io/json-to-go/ and get a correct struct in a fraction of the time?

I use https://marketplace.visualstudio.com/items?itemName=maracko.json-to-go, which is an extension version of https://mholt.github.io/json-to-go/

I think using struct in such cases is almost always the right approach. There are tools which generates go structs from json this.
