cloud command framework

license build central

Cloud is a general-purpose Java command dispatcher & framework. It allows programmers to define command chains that are then parsed and invoked from user- supplied string inputs, to execute pre-defined actions.

Cloud commands consist out of deterministic command chains where the arguments are strongly typed. When you write a command, you know exactly what type of data you will get to work with and you won't need to spend hours debugging command contexts while crying profusely. The experience of using the framework is like floating on a fluffy cloud in heaven. Its feature set is derived from Already existing Command Frameworks, while being less restrictive, opinionated and confusing.

Cloud allows for commands to be defined using builder patterns, like this:

manager.command(
        manager.commandBuilder("command", Description.of("Test cloud command using a builder"), "alias")
                .argument(StringArgument.of("input"))
                .argument(IntegerArgument.<CommandSender>newBuilder("number").withMin(1).withMax(100).build())
                .handler(context -> {
                    String input = context.get("input");
                    int number = context.get("number");
                    context.getSender().sendMessage(String.format(
                            "I am %d%% hyped for %s!",
                            number,
                            input
                    ));
                })
);

or using annotated methods, like this:

@CommandDescription("Test cloud command using @CommandMethod")
@CommandMethod("command|alias <input> <number>")
private void yourCommand(
        CommandSender sender,
        @Argument("input") String input,
        @Argument("number") @Range(min = "1", max = "100") int number
) {
    sender.sendMessage(String.format(
            "I am %d%% hyped for %s!",
            number,
            input
    ));
}

to allow your users to use commands like /command cloud 100.

All this while allowing you to extend and modify the command experience. The framework supports custom (any) command sender types, argument types & parsers, annotation mappers and preprocessors. Cloud also has an advanced command suggestion system, that allows for context aware command completion and suggestions.

If using the annotation parsing system, you can create custom annotation mappers to use your own annotation bindings for command parsing, preprocessing, etc.

Cloud by default ships with implementations and mappings for the most common Minecraft server platforms, JDA and javacord for Discord bots and PircBotX for IRC. The core module allows you to use Cloud anywhere, simply by implementing the CommandManager for the platform of your choice.

The code is based on a (W.I.P) paper that can be found here.

nomenclature

  • sender: someone who is able to produce input
  • argument: an argument is something that can be parsed from a string
  • required argument: a required argument is an argument that must be provided by the sender
  • optional argument: an optional argument is an argument that can be omitted (may have a default value)
  • static argument: a string literal
  • command: a command is a chain of arguments and a handler that acts on the parsed arguments
  • command tree: structure that contains all commands and is used to parse input into arguments

modules

  • cloud-core: Core module containing most of the cloud API, and shared implementations

develop & build

To clone the repository, use git clone https://github.com/Incendo/cloud.git.

To then build it, use ./gradlew clean build. If you want to build the examples as well, use ./gradlew clean build -Pcompile-examples.

use

To use cloud you will first need to add it as a dependency to your project.

Release builds of Cloud are available through the Maven central repository. Snapshot builds of Cloud are available through the Sonatype OSS Snapshot repository.

maven:

<dependency>  
 <groupId>cloud.commandframework</groupId>
 <artifactId>cloud-PLATFORM</artifactId>
 <version>1.4.0</version>
</dependency>
<!-- 
~    Optional: Allows you to use annotated methods
~    to declare commands 
-->
<dependency>  
 <groupId>cloud.commandframework</groupId>
 <artifactId>cloud-annotations</artifactId>
 <version>1.4.0</version>
</dependency>
<!-- For snapshot builds -->
<repository>
 <id>sonatype-snapshots</id>
 <url>https://oss.sonatype.org/content/repositories/snapshots</url>
</repository>

If you are shading in cloud, it is highly recommended that you relocate all of our classes to prevent issues with conflicting dependencies:

<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-shade-plugin</artifactId>
         <version>3.2.4</version>
         <executions>
            <execution>
               <phase>package</phase>
               <goals>
                  <goal>shade</goal>
               </goals>
               <configuration>
                  <createDependencyReducedPom>false</createDependencyReducedPom>
               </configuration>
            </execution>
         </executions>
         <configuration>
            <dependencyReducedPomLocation>${project.build.directory}/dependency-reduced-pom.xml</dependencyReducedPomLocation>
            <relocations>
               <relocation>
                  <pattern>cloud.commandframework</pattern>
                  <shadedPattern>YOUR.PACKAGE.HERE.shaded.cloud</shadedPattern> <!-- Replace this -->
               </relocation>
               <relocation>
                  <pattern>io.leangen.geantyref</pattern>
                  <shadedPattern>YOUR.PACKAGE.HERE.shaded.typetoken</shadedPattern> <!-- Replace this -->
               </relocation>
            </relocations>
         </configuration>
      </plugin>
   </plugins>
</build>

gradle:

repositories {
    maven { url = 'https://oss.sonatype.org/content/repositories/snapshots' }
    mavenCentral()
}
dependencies {
    implementation 'cloud.commandframework:cloud-PLATFORM:1.4.0'
}

To shade and relocate cloud use Gradle Shadow.

Replace PLATFORM with your platform of choice. We currently support: bukkit, paper, bungee and velocityfor minecraft and jda and javacord for discord. All modules use the same versions. More information about the Minecraft specific modules can be found here.
