Autoload a function or completion path. Add the specified list of directories to `$fish_function_path`.
Any `completions` directories are correctly added to the `$fish_complete_path`.
```fish
autoload $mypath $mypath/completions
```
#### `available` _`<name>`_
Check if a program is available to run. Sets `$status` to `0` if the program is available.
Use this function to check if a plugin is available before using it:
```fish
if available battery
battery
end
```
#### `basename` _`<path> ...`_
Wrap basename so it can handle multiple arguments.
#### `refresh`

#### `prompt_segments`
Replace the running instance of fishshell with a new one causing Oh My Fish to reload as well.
