Optional arguments #162
Description
Please describe your suggestion
Optional arguments
Please supply examples of the desired inputs and outputs
Normal usage:
User enters this:
new CommandAPICommand("blah")
.withArgument(new IntegerArgument("int"))
.withOptionalArgument(new IntegerArgument("optional"), 10)
.executes((sender, args) -> {
int arg1 = (int) args[0];
int arg2 = (int) args[1]; // This is 10 if not existant
})
.register();Basically gets converted into this:
new CommandAPICommand("blah")
.withArgument(new IntegerArgument("int"))
.withArgument(new IntegerArgument("optional"))
.executes((sender, args) -> {
int arg1 = (int) args[0];
int arg2 = (int) args[1];
})
.register();and
new CommandAPICommand("blah")
.withArgument(new IntegerArgument("int"))
.executes((sender, args) -> {
int arg1 = (int) args[0];
int arg2 = (int) args[1]; // This is 10, args.length = 2
})
.register();Using annotations:
Either something like this:
@Subcommand("mycommand")
@Arg(name = "int", type = IntegerArgument.class)
@OptionalArg(name = "int", type = IntegerArgument.class, optional = "10")
public void onCommand(int arg1, int arg2) {
//...
}or something like this:
@Subcommand("mycommand")
@Arg(name = "int", type = IntegerArgument.class)
@Arg(name = "optional", type = IntegerArgument.class)
public void onCommand(int arg1, @Default("10") int arg2) {
//...
}Cons of this via annotations is that the value must be a string, primitive, enum, annotation or class, which is really restrictive.
