# NanoDroid-Overlay Script
## Purpose
The `nanodroid-overlay` Script (`novl` for short) is used by NanoDroid to handle the
* Pseudo Debloat Feature (Magisk Mode)
* Force Debloat Feature (System Mode)
### Pseudo Debloat Feature
Magisk allows apps to be magically removed upon runtime. They don't get actually removed from `/system` but they are pseudo-removed during runtime (replaced by a dummy file)
### Force Debloat Feature
In **System Mode**, apps are moved to `/data/media/0/nanodroid_backups/` to be restored from there if necessary.
### Alter the list of pseudo-debloated applications
You can pseudo-debloat applications by adding them to the `.nanodroid-overlay` configuration file on your device, in one of the following directories:
* `/data/media/0` (internal storage (TWRP))
* `/sdcard1` (internal storage (ORANGEFOX))
* `/external_sd` (TWRP path to SD Card (if any))
* `/data` (fallabck)
* `/system/addon.d/` (fallback if TWRP can't mount `/data`)
* `/tmp` (fallback if TWRP can't mount `/data`)
See the [default settings](.nanodroid-overlay) (contains instructions aswell).
The syntax is pretty simple:
* one app per line (no leading spaces)
* name must be an exact match of the **directory** of the app, **not** the app name or app id
* commented out lines (starting with #) are ignored
The following paths are searched for matching apps:
* `/system/app`
* `/system/priv-app`
* `/system/reserve`
* `/system/product/app`
* `/system/product/priv-app`
After you've made your changes, issue the following command on your device, either using `adb shell` or **Termux** as root:
```bash
nanodroid-overlay --update
```
## Invocation
From a terminal on your device, for example `adb shell` or `Termux` invoke the script using either
`nanodroid-overlay [switch] [parameter(s)]` or `novl [switch] [parameter(s)]`
## Overview
`-a`, `--add` [app]
add Overlay for **app** (if it exists) and add it to the config file; [app] is the name of the app's directory in `/system/app` or `/system/priv-app`
`-r`, `--remove` [app]
remove Overlay for **app** (if it exists) and remove it from the config file; [app] is the name of the app's directory in `/system/app` or `/system/priv-app`
`-s`, `--show`
show all apps that **don't** have an Overlay (slow)
`-l`, `--list`
show all apps that **do** have an Overlay
`-x`, `--create`
create Overlays from config file
`-u`, `--update`
**The following features are only available in Magisk Mode:**
remove existing Overlays and re-create them from the config file
`-c`, `--clear`
remove existing Overlays
`-g`, `--genconfig`
(re-)create config file from existing Overlays
## Default Settings
The applications listed in `.nanodroid-overlay` are debloated by default.
