# osu! optimizer (PHP)
[Samsz](https://www.reddit.com/user/kutyaszag) has seen most of my works and it was his idea to combine them together before I start writing another one from scratch.
> "Swiss Army Knife style osu! library manager" -- [Samsz](https://osu.ppy.sh/users/7357064)
## What's this?
This is my attempt at making a somewhat functional multitool for your library. I've had many separate smaller projects in various languages, but I decided to stick with PHP.
There is no real programming style or pattern set for this project, so it's kind of undocumented and hard to read.
Pull requests are welcome! I doubt this project would get any traffic, so feel free to message me directly about basically anything.
## Features
- [x] Replace all backgrounds with 1x1 black images
- [x] Remove storyboard specific files
- [x] Remove background videos
- [x] Remove beatmap skins

- [x] Export maps to .osz
- [ ] Delete maps based on star difficulty
- [ ] Delete maps based on game mode
- [ ] Blacklist: the maps that should not be touched by this program
## Warning!
This project is untested on MacOS. It is not tested thoroughly on Windows either!
You should always back up your osu! folder before using programs of these kinds. I will include a somewhat legal disclaimer just in case.
**Disclaimer**: This code is provided "**AS IS**," I and the other contributors take no responsibility for any harm you may cause to yourself or your computer and its data.
*You have been warned!*
## Usage
You will need PHP 7.4 or later. (Help: [Windows][Windows-PHP], [MacOS][Mac-OS-PHP])
Steps to set up with PHP's built-in solution:
1. Clone or download and unzip the source code.
2. Open a new terminal, powershell window, or command prompt at the source root.
3. Type `php -S 127.0.0.1:1337` and press enter. (Capital -S is important!)
4. Open <http://127.0.0.1:1337/> in your browser.
5. Enter your osu! folder's location and press "Save."
6. Pick your poison.
7. When you're done, terminate the terminal/pwsh/cmd with Ctrl+C.
If you know what you're doing, you could run it on a dedicated server that can handle PHP, but exposing functions capable of file deletion outside the current working directory should never be done on the web. At least bind to localhost.
