command.js

command.js is a library for the SinusBot. It allows to easily create commands via the SinusBots scripting engine. This library requires the v8 engine (SinusBot version 1.0.0+) to function properly. In addition to this library comes with two base commands: help and man.

Work on the stuff which matters and let the command handling do someone else!

Why should I use this library?

This library will standardize the command handling for SinusBot it will help you especially with:

• Argument creation and validation
• Command documentation
• Error handling
• Permission handling
• Command prefix handling

What it can't do yet

• Localization

Documentation

You can find the full documentation for this project on Github Pages.

Example

const engine = require("engine")
const event = require("event")

//this makes sure that all scripts have finished loading
event.on("load", () => {
  //try to load the library
  const command = require("command")
  //check if the library has been loaded successfully
  if (!command) throw new Error("command.js library not found! Please download command.js and enable it to be able use this script!")

  //start declaring your commands from here
  command.createCommand("roll")
    //displays the message when using the `!help` command
    //should be relative short message
    .help("rolls a number")
    //displays this message when using the `!man roll` command
    //more detailed documentation of what this command does
    .manual(`Rolls a number, set a number after this command to use as maximum`)
    //optional permission handling
    //takes a function which first argument will be the requesting SinuSbot client
    .checkPermission(client => {
      //when some criterion is true
      if (someValidationCriterion(client)) {
        //return true so the library will allow the usage of the command to the client
        return true
      } else {
        //return false if you do not want the client to have access to this command
        return false
      }
    })
    //adds an optional argument
    //createArgument("number") creates a new argument which expects a number
    //setName("max") sets the name of the argument to identify the argument later
    //integer() tells the number argument to expect a whole number (not a floating point)
    //min(1) tells the argument that the number should be greater or equal to 1
    //optional(defaultVal) this flag tells it to be a value which does not necessarily be omitted
    //  the defaultVal will be used when no argument has been omitted
    .addArgument(command.createArgument("number").setName("max").integer().min(1).optional(10))
    //this function gets called when validation was successful and all arguments have been parsed successful
    //client - is the user which executed the command
    //arg - is an object which holds all parsed arguments which name has been set via the arguments .setName() function
    //reply - depending on where the client has sent the message it will automatically reply to the client, channel or server chat
    //ev - the raw event which has been received
    .exec((client, { max }, reply, ev) => {
      reply(`Rolling with 0-${max}`)
      const random = require("helpers").getRandom(max)
      reply(`You rolled ${random}`)
    })
})
