Create a Command Alias (0.0.9 to 0.2.0)

Command Aliases File will be located in config/commandaliases.json. If you are using Sublime Text, enable Regular Expressions with Alt+R and Case sensitive with Alt+C. Here is the pattern being used (\{(?<classTool>\w+)(::(?<method>[\w:]+))?(#(?<variableName>\w+))?(@(?<formattingType>\w+))?})

Here is an example with comments.

[
	{
		"command": "tools",
		"_command": "Create a new command /tools",
		"execution": [
			{
				"command": "give {this::SELF} minecraft:wooden_sword 1",
				"_command": "{this::SELF} rebinds to the player who executes the /tools",
				"type": "SERVER",
				"_type": "CLIENT will execute the command client sided, if you don't have OP permissions, the command give won't be executed. SERVER will execute the command as the SERVER",
				"messaage": "Giving Wooden Sword",
				"_messaage": "Optional Message",
				"sleep": "500",
				"_sleep": "Sleeps in milliseconds, you can also specify an execution class tool on it"
			},
			{
				"command": "give {this::SELF} minecraft:wooden_pickaxe 1",
				"type": "SERVER"
			},
			{
				"command": "give {this::SELF} minecraft:wooden_axe 1",
				"type": "SERVER"
			},
			{
				"command": "give {this::SELF} minecraft:wooden_shovel 1",
				"type": "SERVER"
			}
		],
		"message": "Here are some free wooden tools, {this::SELF}!",
		"_message": "Optional Message that will be sent to the user, you can also specify an execution class tool on it"
	},
	{
		"command": "sidebar {arg::objective#objective}",
		"_command": "Creates /sidebar, required parameters are bound within {classTool::method#variableName}. This also creates the command with tab completion",
		"execution": [
			{
				"command": "scoreboard objectives setdisplay sidebar {objective}",
				"_command": "Our variableName is objective, any input in the place of {objective}",
				"type": "SERVER"
			}
		],
		"message": "Objective {objective} set for {this::SELF}!"
	},
	{
		"command": "foo {arg::greedy_string#message}",
		"execution": [
			{
				"command": "tellraw @a {\"text\":\"{message@jsonString}\"}",
				"_command": "Calling format types with @, currently jsonString(escapes some characters), toLower, toUpper",
				"type": "CLIENT"
			}
		]
	}
]

After editing the json you can run /commandAliases reload to reload them.

Argument types can be found here and here. There are some arguments that are currently unavailable.

Reassigning commands

You can also reassign existing commands using this format

{
	"command": "help",
	"_command": "The command literal to reassign",
	"reassignOriginal": "minecraft:help",
	"_reassignOriginal": "The new command literal to reassign to",
	"reassignOnly": true,
	"_reassignOnly": "This field isn't mandatory it's default value is false meaning you can directly create a command alias within this object. If you set this to true it will only reassign them and the the execution and message fields are ignored",
	"execution": [
		{
			"command": "give {this::SELF} minecraft:wooden_sword 1",
			"_command": "{this::SELF} rebinds to the player who executes the /tools",
			"type": "SERVER",
			"_type": "CLIENT will execute the command client sided, if you don't have OP permissions, the command give won't be executed. SERVER will execute the command as the SERVER",
			"messaage": "Giving Wooden Sword",
			"_messaage": "Optional Message",
			"sleep": "500",
			"_sleep": "Sleeps in milliseconds, you can also specify an execution class tool on it"
		},
		{
			"command": "give {this::SELF} minecraft:wooden_pickaxe 1",
			"type": "SERVER"
		},
		{
			"command": "give {this::SELF} minecraft:wooden_axe 1",
			"type": "SERVER"
		},
		{
			"command": "give {this::SELF} minecraft:wooden_shovel 1",
			"type": "SERVER"
		}
	],
	"message": "Here are some free wooden tools, {this::SELF}!",
	"_message": "Optional Message that will be sent to the user, you can also specify an execution class tool on it"
}

Optional arguments commands

You can also reassign existing commands using this format

{
  "command": "foo {arg::brigadier:bool#bool} [arg::player#player@jsonString] [arg::greedy_string#message@jsonString]",
  "_command": "You can set optional argument usings [] similar to required arguments",
  "execution": [
	{
	  "command": "tellraw @a {\"text\":\" {bool} [message] [player]\"}",
          "_command": "If [message] or/and [player] is no entered by the user it is replaced by blank spaces",
	  "type": "CLIENT"
	}
  ]
}
