Add proof of concept for Thot.Json code generation

[alfonsogarciacaro]

Instructions :)

cd tools/CodeGenerator
dotnet run ../path/to/Project.fsproj Namespace.WithTypes

[alfonsogarciacaro]

Don't look at ProjectCoreCracker.fs, I don't understand it either ;) Check Program.fs, the types in FCS can be a bit tricky, please ask me if you have questions (right now the tool asumes all types are records).

[MangelMaxime]

Oups, I looked at ProjectCoreCracker.fs

Thanks for the code, I will play a bit with it :)

Let me know if you need some complex encoding / decoding examples, I have a few spots I'm converting to Thot that I can point you at.

[MangelMaxime]

@jgrund Are you using custom decoders ?

In my complexe structure, I am using some of them for decoding Date for example. I wonder, if I should not add an extension to Thot.Json for common decoders like that.

[jgrund]

Date seems like something that could be configurable on the encoding side at least (different consumers may work with different datetime representations).

I'm converting a bunch of code from {of/to}Json to use Thot. I've needed one custom transform to deal with somewhat dynamic key names. Besides that it's dealing with a bunch of DU's and large records and a recursive DU.

[MangelMaxime]

Oh I don't think I have recursive DU in my code base so yes if you can share some types that could help us :)

https://github.com/intel-hpdd/rust-libzfs/blob/master/Fable.Import.NodeLibzfs/fable/NodeLibzfs.fs

Has a bunch of types I just converted to use Thot. Recursive bit is any field that contains VDev array.

[MangelMaxime]

Awesome thank you :)

I am abusing, if I ask for a json ? I didn't look at the repo to see if it's easy to produce one or no.

[jgrund]

Sure, we have tests that are covering everything here (and have JSON strings that are being decoded): https://github.com/intel-hpdd/rust-libzfs/blob/master/Fable.Import.NodeLibzfs/test/NodeLibzfs.Test.fs

And generated snapshots for the output here (that have JSON strings output from encoding): https://github.com/intel-hpdd/rust-libzfs/blob/master/Fable.Import.NodeLibzfs/test/__snapshots__/NodeLibzfs.Test.fs.snap

I am closing in favor of #20 , I already started a discussion with Krys about that.
