[SCRIPT] RetroPie Shell Script Boilerplate

meleu

@hiulit OMFG! I was thinking about making the same thing but was a bit unmotivated to start it from scratch. Now you started it... such a relief! :D

After writing all those scripts here and there for the RetroPie community I think I have something to share. I hope to find some time to contribute on your repo.

Thanks for bringing this up!

@cyperghost I'm glad you like! :D
I like to use config files because it makes the script more 'user-friendly' in my opinion. Feel free to contribute to the repo if you find a better way of handling config files (setting and getting values)

@meleu Awesome! I'm already waiting for your contributions! And any other person who'd like to contribute too.
Together we can come up with a nice and useful boilerplate :)

@hiulit I think the comments are kinda wordy. Would you mind if I change the style, trying to reduce the text a bit?

hiulit

@meleu Yeah, sure, no problem! Go for it!

@hiulit PR submitted.

I've updated the RetroPie Shell Script Boilerplate:

UPDATE 1:

Merged #2 from @meleu .
Added check_dependencies().
Added reset_config() to use it in conjunction with set_config() and get_config().
Added --version (because I think everyone should use it :P)
Added 2 ways to find /home.
Added more useful global variables.

These changes are also reflected in the first comment.

Coming soon... dialog functions!! Again, thanks to @meleu ;)

@hiulit Some additional functions

# This will determine of savestate directory = config
# This is part of hiuilits Boilerplate script, with small modification
# if '~' is detected then expand full homepath
function get_config() {
    local config
    config="$(grep -Po "(?<=^$1 = ).*" "$CONFIG_FILE")"
    config="${config%\"}"
    config="${config#\"}"
    # [[ ${config:0:1} = "~" ]] && config="${config#??}" && config=~/"$config" # Expand homepath
    # [[ -z ${config##*/} ]] && config="${config%?}" # Sanitize pathes if last character is a /
    # [[ ${config:0:1} != "/" ]] && config="annother value because it is likely no path"
    echo "$config"
}

# This will determine which script is curently running
# Is it 'runcommand-onend.sh' or 'runcommand-onstart.sh'
# It will extract 'end' or 'start' ... Usefull if you need to know which runcommand called the script
function get_runcommand() {
   local i
   local file_array=("runcommand-onend.sh" "runcommand-onstart.sh")
   for i in "${file_array[@]}"
   do
      [[ $(pgrep -f "$i") ]] && i="${i#*-on}" && echo "${i%.*}"
   done
}

# Determining file ages
function file_age() {
    echo "$(date +%s -r "$1")"
}
