About commandList and taskList

The content of taskList or commandList is defined as json object, the key of the json is command name or task name, here is the structure of command or task:

{
  commandOrTaskName:{
    description: '',
    messagesOrTask: [] //(function)
  }
}

commandOrTaskName is the command name you defined.

description is something to describe your task, which will be used by the help command.

messagesOrTask is the main part defined to response the command, in commandList, the key is messages, and in taskList the key should be same with task name, here is the detail:

• messages (array)

  messages is an array of Message, you can only show message string in terminal instance as a response to a command.

• task (function)

  you can do more with task, task is a function which use taskName as function name, the first argument is pushToList, which is a function allow you to send message to the terminal instance, you can call pushToList(Message) to render message in the terminal, the second argument is the string user input, your can parse it and do something interesting. You must return a resolved Promise to tell terminal instance that the task has ended, so that the terminal instance can get ready for more command.

• Message

  Message is an object, used to define message showed in terminal:

  {
    time: '', // time to show time before message body
    label: '', // label to show a label before message body
    type: '', // type to set message's type, will set a class to message's label part, there is 5 builtin types: error, success, info, warning, system
    message: '' // message is a string, the main text showed in terminal.
  }
  

  here is an example:

    { time: generateTime(), type: 'system', label: 'System', message: 'Welcome to vTerminal, this is an example to show you what this project can do.' },
  

You can check /docs/plugins/commandList.js and /docs/plugins/taskList.js to view the detail of task and command config.
