So, @enum is causing me major problems: I can’t use the names I want to use because it puts the names directly in the namespace. I need to go back and forth between strings and enums easily. Override Base.show for enums doesn’t appear to work. I don’t want to put it in a little module by itself to…

[image] taotree: I need to go back and forth between strings and enums easily. Can you explain this more? How are strings related to enums?

In this particular case, the enums match up with sets of values going to/from an external system as strings in JSON. I was using that @scopedenum solution I linked to for a little while, but then ran into it contributing to a performance issue because I had to run various logic/calculations some mi…

I need to go back and forth between strings and enums easily. Maybe this does what you need? @enum Foo x y string(x) string(y) eval(Symbol("x")) eval(Symbol("y"))

I was using that @scopedenum solution I linked to for a little while, but then ran into it contributing to a performance issue because I had to run various logic/calculations some millions of times. This seems surprising because they should just be treated like constants, no? Have you posted abou…

@enum’s are just numeric constants, but the @scopedenum macro does some magic with a struct inside a module, so apparently something is going on. I just ran into it yesterday and haven’t reported it anywhere.

It seems like the baremodule version hits your needs, with the only downside of needing different names for the type and module. But that seems minor? Or am I missing something?

[image] BioTurboNick: It seems like the baremodule version hits your needs, with the only downside of needing different names for the type and module. You can make a module without a reference to itself in Julia 1.8, which might let you make a type named M in a module named M. …

As for how minor it is, depends on how you look at it. Code needs to be as readable as possible for maintenance, but… conventions are required to be known in some cases, apparently this is one of those situations. I was asking this question in case there was new information that solves all these is…

There is also an enum in MLStyle, but it uses the type domain iirc. Algebraic Data Types — MLStyle.jl Documentation
