Huge update of the README (finally)
Autoenv for Zsh
zsh-autoenv automatically sources .env files, typically used in project
root directories.
It handles "enter" and leave" events, nesting, and stashing of variables (overwriting and restoring).
Features
- Support for enter and leave events, which can use the same file.
By default
.envis used for entering, and.env_leavefor leaving. - Asks for confirmation / authentication before sourcing a
.envfile, and remembers whitelisted files by its hash. - Test suite.
- Written in Zsh.
Variable stashing
You can use autostash in your .env files to overwrite some variable, e.g.
$PATH. When leaving the directory, it will be automatically restored.
% echo 'echo ENTERED; autostash FOO=changed' > project/.env
% FOO=orig
% cd project
Attempting to load unauthorized env file!
-rw-rw-r-- 1 user user 36 Mai 6 20:38 /tmp/project/.env
**********************************************
echo ENTERED; autostash FOO=changed
**********************************************
Would you like to authorize it? (type 'yes') yes
ENTERED
project % echo $FOO
changed
% cd ..
% echo $FOO
orig
There is also stash, unstash and autounstash, in case you want to
have more control.
The varstash library has been taken from smartcd, and was optimized for Zsh.
Writing your .env file
autoenv_source_parent()
zsh-autoenv will stop looking for .env files after the first one has been
found. But you can use the function autoenv_source_parent to source a
parent .env file from there.
Installation
Clone the repository and source it from your ~/.zshrc file:
% git clone https://github.com/Tarrasch/zsh-autoenv ~/.dotfiles/lib/zsh-autoenv
% echo 'source ~/.dotfiles/lib/zsh-autoenv/autoenv.zsh' >> ~/.zshrc
Using antigen
antigen-bundle Tarrasch/zsh-autoenv
Using zgen
Add the following to your .zshrc where you are loading your plugins:
zgen load Tarrasch/zsh-autoenv
Configuration
You can use the following variables to control zsh-autoenv's behavior.
Add them to your ~/.zshrc file, before sourcing/loading zsh-autoenv.
AUTOENV_FILE_ENTER

History
This started as a optimized version of autoenv for Zsh, but grew a lot of functionality on top of it (inspired by smartcd).
The code was initially based on Joshua Clayton's work.
