Slightly related but mise, a tool you can use instead of eg make, has “on enter directory” hooks that can reconfigure your system quite a bit whenever you enter the project directory in the terminal. Initially I was horrified by this idea but I have to admit it’s been quite nice to enter into a directory and everything is set up just right, also for new people joining. It has built in version management of just about every command line tool you could imagine, so that an entire team can be on a consistent setup of Python, Node, Go, etc.
I see other people mentioning env and mise does this too, with additional support to add on extra env overrides with a dedicated file such as for example .mise.testing.toml config and running something like:
MISE_ENV=testing bun run test
(“testing” in this example can be whatever you like)
