OrderedStruct failure

[alunap]

Version 1.7.1 fails to precompile, saying that it is unable to load OrderedStruct. StructTypes = 1.4.0. (actually loading JSONTables here, which loads JSON3).

Reverting JSON3 back to v1.5.1 deals with the problem.

[quinnj]

There's a good way to check whether you have the right versions of things; can you post the output of:

using StructTypes, JSON3
@show StructTypes.Struct
@show JSON3.StructTypes.Struct

can you also show what version of Julia you're running and from where? REPL? Juno/Atom? VS Code? Jupyter?

[alunap]

Sure,. I'll update the packages again to see the issue. I'm using JuliaPro 1.5.3-1 / Atom.

[quinnj]

If you just do:

using StructTypes
@show StructTypes.Struct

what is output? This seems to be a case where Juno is including an old version of StructTypes that bypasses all the version-checking and is messing JSON3 up.

[alunap]

julia> using StructTypes

julia> @show StructTypes.Struct
StructTypes.Struct = StructTypes.Struct
StructTypes.Struct

[alunap]

regarding manifests, and so on, there is a project and manifest.
Project.toml
StructTypes = "856f2bd8-1eba-4b0a-8007-ebc267875bd4"

Manifest.toml
[[StructTypes]]
deps = ["Dates", "UUIDs"]
git-tree-sha1 = "d7f4287dbc1e590265f50ceda1b40ed2bb31bbbb"
uuid = "856f2bd8-1eba-4b0a-8007-ebc267875bd4"
version = "1.4.0"

[quinnj]

julia> @show StructTypes.Struct
StructTypes.Struct = StructTypes.Struct
StructTypes.Struct

Yeah, this confirms that an older version of the StructTypes package is getting loaded by Juno (as suspected). In StructTypes 1.4, you would see StructTypes.UnorderedStruct get returned. If you open julia from a normal terminal (outside atom/juno), and run the same result, you'd see the correct code.

Talking with Juno devs on slack, it sounds like this is indeed a Juno issue. So feel free to open an issue w/ them, but I'm afraid there's not much we can do on the JSON3/StructTypes side of things.
