Ascension Launcher Updater (Bash Script)
-
greetings fellow unix gamer
it is my greatest pleasure to inform you, that the Ascension Launcher Updater (or ALU for short) now inoffically official hit public pre alpha. what does it do? it searches for the latest version of the ascension launcher and downloads it, without the need to open a browser, without the need to log into your account and click to many buttons to even bother. how many packages do you need to add i hear you ask? none. assuming you got 'curl' and 'wget'. which you do. most likely.
the ALU is a simple yet extremely unoptimized bash script, that could be executed on your machine today! gone are the anoying days of the launcher telling you to manualy update. the ALU even sets execution permission and asks you if it should launch the launcher. amazing. but how does it work? simple. put it in the directory where your ascension launcher is located and make sure you did not rename the official launcher. now just run the script in your favorite terminal that knows how to handle bash and you are all set up.
are you afraid of terminals? don't be, they can smell your fear. the ALU is operated by simple yes or no questions, even my cat could operate it without error. and i don't even have a cat.i did some intensive edge case testing, which i think are now all covered. this in turn lead to some serious bloat in redundant code, but you know what? the ALU is already perfect as is, it does not need a switch case. and here it is, get hyped, buckle your pants and most importantly hydrate well, here it is, 299 lines of madness, the one and only, ALUv001.sh:

i updatet the script and please be advised that it is now very sexy.
much more refinde, less bloat, less asking for unnecessary confirmations. one might just asume that the whole reason for the old script to exist is to make this new shiny one look even better. without further ado, godhood brought to script:#!/bin/bash echo " + " echo " | ALU " echo " | Ascension Launcher Updater" echo " + " echo " " echo "welcome to the launcher launcher" echo " " VERSION_MIN=0 VERSION_MAX=999 if [ ! -f current_version.txt ]; then echo " " echo "first time launch" echo " " touch current_version.txt mkdir old_launchers if [ ! -f ascension-launcher-*.AppImage ]; then echo "[ERR] no launcher found" echo "${VERSION_MIN}" > current_version.txt echo "[ERR] make sure this script is in the same directory as the ascension launcher" echo "[ERR] make sure you have not renamed the ascension launcher" echo " " echo "[ERR] the script will search for updates starting with version ${VERSION_MIN}" echo "[ERR] this may take a while" echo " " read -r -p "set next starting value manualy?
