Topic: ✔ Nested environments?


view this post on Zulip Richard Reeve (Apr 26 2022 at 21:24):

This seems like an obvious question, but I can't find the answer anywhere. I want to have all of my environments to have Revise installed, but I don't want to have to do that manually because Revise isn't relevant to the specific project - for instance I want to have Revise installed in every environment in every examples folder in every package I write without specifying it. Is there any way of automatically including some environment (i.e. some global Project.toml / Manifest.toml) in any current environment? Or maybe a way of nesting one environment inside another?

These are rather called "stacked" environments.
See https://discourse.julialang.org/t/why-not-always-use-revise/64589/6

It should be sufficient to add Revise to the default environment to make it available while activating project and package environments.

Thanks. I honestly had no idea that worked after god knows how long using Julia now. I can't help but feel it should be better documented! Presumably it means that I don't know without putting stuff in CI on github whether I've actually put the right dependencies into a new environment though if Julia automatically pulls things that I have in my global environment into any local environment? Is there anyway of switching it off?

Just tested it, on my computer when I run pkg> test, it does not use packages from the default environment (thank God!)
