Bis jetzt waren alle Lua Codes in luarc. Das war ein guter Weg, um dir ein Skript zu entwickeln, aber weniger praktikabel für eine Weitergabe. Das müssen in einem eigens dafür bestimmten Lua Modul. Um das zu machen, sichern wir den Code in eine separate Datei (scp-storage.lua für diesen Fall):

Ansel wird Skripte suchen (den normalen Lua Regeln folgend) in den Standardverzeichnissen plus $CONFIGDIR/lua/*.lua. So kann unser Skript aufgerufen werden, indem man einfach an die Datei anfügt require "scp-storage" in the luarc file. Einige extra Bemerkungen…

  • The function Ansel.configuration.check_version will check compatibility for you. The “...” will turn into your script’s name and {2,0,0} is the API version you have tested your script with. You can add multiple API versions if you update your script for multiple versions of Ansel.

  • Make sure to declare all your functions as local so as not to pollute the general namespace.

  • Make sure you do not leave debug prints in your code – Ansel.print_error in particular allows you to leave debug prints in your final code without disturbing the console.

  • You are free to choose any license for your script but scripts that are uploaded on Ansel’s website need to be GPLv2.

Once you have filled all the fields, checked your code, you can upload it to our script page here .
