A Kotlin DSL wrapping Mojang's Brigadier builder. See BrigadierDSL.kt.

Every single call is inlined, so there's no performance cost to using this over the original. Hope this helps!

Example Usage:

import btpos.dsl.brigadier.Command

// Start the command tree
Command.literal<CommandSourceStack>("find") {
    // Add a literal. Command at this point is "/find my"
    "my" {
        // Add a "string" argument with the name "item_arg"
        "item_arg"(StringArgumentType.string()) {
            requires { it.isPlayer }
            // Add suggestions. The ! operator adds a literal, and the invoke adds a literal with a tooltip.
	    // (The + operator was already taken on integers.)
            suggests { ctx ->
                !"ball"
                !1
                "car" { "This will be a tooltip!" }
                2 { "This will be another tooltip!" }
                withOffset(5) {
                    "future" { "Using knowledge of later words!" }
                }
            }
            executes { ctx ->
                val toFind = ctx.optionalArgument<String>("item_arg")
                    ?: return@executes ctx.sendFailure("You didn't ask for an item!")
                
                if (toFind == "car")
                    return@executes ctx.sendSuccess("vroom!")
                
                return@executes Command.FAIL
            }
            "here" {
                executes(::myCommand)
            }
	   // If you have another function that produces a LiteralArgumentBuilder or a previously-compiled CommandNode, 
	   // add it with +
            +makeSubCommand()
        }
    }
}

There's also redirect and fork support, as well as anything else I could find in the assorted builders.

I also did my best to document the dang thing. I still don't fully understand what half of it does, but I did my best.

More macros are available in MCSpecificMacros.kt for working with Minecraft specifically. Just pop the file in your project yourself if you want to use them; I couldn't be bothered to get a standalone MC build working here.

Add as a Dependency

Gradle:

repositories {
    mavenCentral()
    maven(url="https://jitpack.io")
}

dependencies {
    implementation(jarJar("com.github.bythepowerofscience:brigadierdsl:1.0.0"))
}

If you're using ForgeGradle:

dependencies {
    implementation(jarJar("com.github.bythepowerofscience:brigadierdsl:1.0.0")) {
        jarJar.ranged(this, "[1,)")
    }
}
