# Autoenv for zsh
|
||||
# Autoenv for Zsh
|
||||
|
||||
This is is a zsh optimized version of
|
||||
[autoenv](https://github.com/kennethreitz/autoenv)
|
||||
zsh-autoenv automatically sources `.env` files, typically used in project
|
||||
root directories.
|
||||
|
||||
## Why a zsh version
|
||||
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 `.env` is used for entering, and `.env_leave` for leaving.
|
||||
- Asks for confirmation / authentication before sourcing a `.env` file, 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!

|
||||
|
||||
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.
|
||||
|
||||
* Auto-completion will work rather than vomit
|
||||
* No stupid error messages
|
||||
* It's elegant to use the built in `chpwd_functions`

## Credits
|
||||
### AUTOENV\_FILE\_ENTER
|
||||
Name of the file to look for when entering directories.
|
||||
|
||||
The code was mostly copied from [Joshua Clayton](https://github.com/joshuaclayton)
|
||||
Default: `.env`
|
||||
|
||||
### AUTOENV\_FILE\_LEAVE
|
||||
Name of the file to look for when leaving directories.
|
||||
Requires `AUTOENV_HANDLE_LEAVE=1`.
|
||||
|
||||
Default: `.env_leave`
|
||||
|
||||
### AUTOENV\_LOOK\_UPWARDS

||||
Default: `1`
|
||||
|
||||
### AUTOENV\_HANDLE\_LEAVE
|
||||
Handle leave events when changing away from a subtree, where an "enter"
|
||||
event was handled?
|
||||
|
||||
Default: `1`
|
||||
|
||||
### AUTOENV\_DISABLED
|
||||

## History
|
||||
|
||||
This started as a optimized version of
|
||||
[autoenv](https://github.com/kennethreitz/autoenv) for Zsh, but grew a lot of
|
||||
functionality on top of it (inspired by
|
||||
[smartcd](https://github.com/cxreg/smartcd)).
|
||||
|
||||
The code was initially based on [Joshua Clayton](https://github.com/joshuaclayton)'s work.
