Example: + Let's say I have a command /tp <player_to_teleport> <destination_player>. The usage is: "<player_to_teleport> <destination_player>". + I suggest we use the same format throughout redstoner-utils: + - Separate arguments by spaces; + - Use <> if the argument is required, and [] if the argument is optional; + - Add .. to the argument's identifier (name) if it is for example a message (containing spaces). + for example in /msg, the usage would be "<player> <msg..>" + +* description: a description of what the command does. Defaults to "Handles cmd". + This is used for the help message, where the description is (meant to be) indented. To keep this indentation + with longer descriptions, call the help message (with the command, ingame) and add '\n' + when it jumps to a new line in the chat. The decorator will take care of the indentation after that. + +* senderLimit: an integer resembling the accepted sender type. Defaults to -1. Use: + -1 for console as well as players; + 0 for players only; + 1 for console only. + +* amin: an integer resembling the minimum amount of arguments. Defaults to 0 +* amax: an integer resembling the maximum amount of arguments. Defaults to -1, which means that there is no maximum. + +* helpNoargs: a boolean value resembling whether the help message should be displayed when no arguments are given. + Defaults to False. + +* helpSubcmd: a boolean value resembling whether the help message should be displayed when the first argument.lower() equals "help". + Defaults to False. + +Comments on the function added to the decorator: +It should return a message to send to the player. Color codes are translated automatically. It can return None or an empty string to send nothing. + +Inside the function, calls to static methods in the class Validate can be used to make the code shorter and easier to write (maybe not easier to read). +For example, to make sure that a condition is met, use Validate.isTrue(condition, message to send to the player if the condition is not met) +Don't forget to `from basecommands import Validate` if you wish to make use of this. +For all other Validate checks, see the code below. Feel free to add your own. + +Instead of returning a message mid-code to describe an error, you can also use raise CommandException(msg), but it is almost always possible +to replace this return statement with a call to one of the functions in the Validate class.
