### `autoenv_source_parent()`
|
||||
|
||||
zsh-autoenv will stop looking for `.autoenv.zsh` files after the first one has
|
||||
been found. But you can use the function `autoenv_source_parent` to source a
|
||||
parent `.autoenv.zsh` file from there.
|
||||
zsh-autoenv will stop looking for `.autoenv.zsh` files upwards after the first
|
||||
one has been found, but you can use the function `autoenv_source_parent` to
|
||||
source the next `.autoenv.zsh` file upwards the directory tree from there.
|
||||
|
||||
The function accepts an optional argument, which allows to stop looking before
|
||||
the file system root is reached:
|
||||
|
||||
```zsh
|
||||
autoenv_source_parent ../..
|
||||
```
