Make your fish feel better in the environment of trees.
(or an improved version of autoenvfish)
Fish plugin. Once installed, it will do essentially the following
- if you enter some directory and there's
.env.fishinside, it will be sourced - if you leave that directory, the file will be "unsourced"
"Unsourcing" means restoring back global shell variables (exported or not).
There could be multiple .env.fish on different levels of folder structure.
Diving into such a tree with a single cd command would cause them to be
sourced in order. Global variables are retained at each level, so returning
would unsource files in reversed order. It works similarly to the concept of
local scope variables in some programming languages, including fish.

fisher OpenINF/openinf-autoenvstack
In ~/play/.env.fish settitle sets a global variable that is displayed both in
the title and command prompt.
In both ~/play/scrapy/.env.fish and ~/play/flask/.env.fish Python virtual
environment is activated.
By moving around, files are sourced and unsourced, eventually restoring the initial state of the global variables.
If, under some circumstances, autoenvstack removes all your globally declared variables (no colors, git complains), clean up the cache of universal variables:
rm -f ~/.config/fish/fishd.*
