 An enhanced version of the ŠkolaOnLine (ŠOL) online school system.

-It aims to provide more readable data than the web version and remove some of the annoyances of the mobile app. It is intended to be an Android app in the future, but so far it is **only for Linux** (not tested anywhere else).

 The implementation consists of a local (or maybe remote in the future) server which does the webscraping and session stuff and the actual Android app which shows the data.

-To start, you need to set the server up (guide in the /server directory of this repo) on localhost (127.0.0.1) on port 8080 using Termux (tested like that, maybe you can find an another way to host a server on mobile) and it needs to be serving the file fetch.php.

 To set the server up, run the `run_server.sh` script found in the /server directory.
