Useful Arch Linux Script Vault
This is ualsv. a script that can apply patches to files, or restore them to their original state if necessary.
Execute ./ualsv.sh help for more information
Do not forget execute install -Dm755 checkutils.sh /usr/local/share/ualsv/checkutils.sh
The ualsv_db repository is available, from which all packages will now be downloaded. If you would like to post your patch, please send me a Merge Request
I'm still thinking about where I should store and whether I should store the script files for this program at all. But as soon as I do, I will definitely report it here. And at the expense of writing your script, I will now show you one of the examples:

├── backup
├── framework
└── files
├── patch.conf
├── something.desktop
└── one.patch

print_help() {
cat <<EOF
msg echo this if needed
EOF
}
framework() {
echo $1 $2
}
Next, files.
patch.conf
+one.patch:/var/run/some/file
second.patch:$HOME/some/file
By adding a + to the beginning of the line, you specify that the patch should be overlaid using sudo
In the field after the colon, you can use variables, as well as various characters, such as ~. For their escape, eval is used
You can also look at the example folder, which contains a script to turn off tearing on Intel embedded
The check function is executed BEFORE installing packages from the $packages and $aur arrays.
If you want to list all the commands that the second checkutils.sh script provides, run sed -n 's/^\([^(]\+\)()\s{$/\1/p' checkutils.sh
You can also put files that are not related to patches in the files folder. For example, something additional that will be used later during the execution of the script
You can download only frameworks (without patches and script file).
