JCommands

With this Javacord extension you can create Slash Commands on your Discord server within 1 minute with built-in

• input validating,

StringArgument<Integer> stringArgument = new StringArgument<>("number", "A number", Integer.class);  
stringArgument.getArgumentValidator().when(RegexPredicate.notValidFor("\\d+")).thenRespond(event -> {  
    event.getResponder().respondNow()  
        .setContent("The input is not a number!")  
        .respond();  
});  

• value converting,

stringArgument.convertResult(value -> Integer.parseInt(value));  

• autocompleting and

StringArgument<String> searchArgument = new StringArgument<>("search", "Start typing", String.class);  
SearchAutocomplete searchAutocomplete = new SearchAutocomplete(SearchAutocomplete.SearchType.CONTAINS, Arrays.asList(  
    "just some words like hello world"  
    .split(" ")  
))  
.ignoreCase();  
searchArgument.addAutocomplete(searchAutocomplete);  

• concatenating

command.addConcatenator(new StringConcatenator<>(" ", String.class), stringArgument, searchArgument);  

There are so many useful pre-written argument types that can be used while creating a command.

Example command

This command is created just with about 50 lines of code including the response and error handling. It has a validated argument with regex, an argument that has two different values that the user can choose from, a number argument that has a range validation, a normal user mention argument, a normal channel mention argument and an optional attachment argument with size and extension validation.

You can find the full code here that runs a bot with the example command above.
