Sets environment variables when you enter a directory. Works with bash, zsh, and fish.
At work, I have to set some environment variables every time I'm working on certain projects.
For example, these can be Google Cloud settings, the Consul host, or Docker configs.
It's tedious to set the correct environment variables myself every time.
[direnv] automatically loads .env files, but I don't want to clutter my system
with .env files. Also, I need the same environment variables in a few unrelated
projects, and I don't want to keep the .env files in sync.
Thus, the idea for envy was born.
It uses a config file that defines what environment variables to set for each folder.
cargo install envy-cli
Add the following line to the end of your ~/.zshrc file:
zsh
eval "$(envy hook zsh)"
For bash, use envy hook bash instead and add it to your ~/.bashrc file.
bash
eval "$(envy hook bash)"
For fish, use envy hook fish instead and add it to your ~/.config/fish/config.fish file.
fish
eval (envy hook fish)
Once you open a new shell, envy will start matching directories and set the specified
environment variables from the config file.
Run envy edit to open the config file.
(On macOS, this file is located at /Users/<user>/Library/Application Support/Envy/Config.toml.)
Define the list of regular expressions and the settings. The first regular expression that matches a path wins.
```toml [[paths]] pattern = ".project1." env = [ "CONSULHTTPADDR=http://consul:8500", "GITHUB_TOKEN=123" ]
[[paths]] pattern = ".project2." env = [ "DOCKER_HOST=tcp://127.0.0.1:2376", "foo=bar" ] ```
The moment you save the file, the current terminal will automatically pick up the new settings; no need to reload or open a new terminal. :v:
envy supports loading environment files à la direnv as well. Run envy allow .env to auto-load the .env file in the current path on enter. You can add
multiple .env files (e.g. envy allow .envrc). Duplicate keys will be
overwritten in the order of appearance in the envy config file (run envy edit
to modify order).
Use envy deny .env to remove an environment file from the list.
``` envy 0.4.0 context-based environment variables
