LDQ For a practlang, should you be allowed to directly access transitive dependencies?

my vote is no

it's pointless/confusing at best and could complicate the very idea of the user-facing api at worst

like, fundamentally, dependencies aren't anything different from your own library's guts

so there's no reason to expose them when you don't want to

@mousetail I also feel like the answer should be no. By using library imported by something else, there's nowhere in the code that explicitly mentions that library is being used. Also, if the library you've explicitly imported stops using the library you're using transitively, you all of a sudden have a whole bunch of namespace errors

Like all good design practices aside, dependency management is already messy. No need to make it even more complicated by having quasi-dependencies

LDQ If a library is used via 2 different dependencies, should both versions share any mutable globals and statics?

lyxal

Example syntax?

(just so I can see what you mean)

emanresu A

I've never seen a library with mutable globals. It's just not how libraries work

mousetail

Many libraries do, most famously react

Basically if you have something like this:

int a(b) {
   static int c;
   if (b) c=b else b=c;
   f(b)
}

Specifically in React you can have issues since many libraries rely on the global state to match other libraries. But this creates problems since sometimes libraries can get their own react versions with their own static and everything breaks

I thought you could just not allow static sharing even if the versions match, so you'd be forced to explicitly pass references to them to everything that needs it, to avoid this issue

Flask is also a library that makes a lot of use of global statics

Though in python you can't really install 2 versions of the same library so the program would just break instead of these hard to track down bugs

That doesn't sound like a good idea then

Unrelated String

i feel like if you have a library that has mutable globals you need to somehow encapsulate it into something you can make distinct instances of before doing literally anything else with it

because that's fundamentally not a library

that's a god object you can treat like a library

mousetail

Then you'd need someObject.useState everywhere in react

Unrelated String

good.

(presumably you'd also have some way to put stuff from the library-object in scope like with a normal sane library :P)

mousetail

The issue is not so much with the syntax as with needing to pass the object around everywhere

Though flutter works something like that already so I guess it's possible
