Installation

What it does?

This software is distributed with an agent (afk_agent) and a client (afk, optional).

The agent is designed to be run in the background and stay active until you terminate it.

Features implemented by the agent

• waits for lock screen and unlock screen events
• connects to a Slack workspace, and change user status on lock (clean it on unlock)
• optionally: write a message on a channel on lock/unlock

Prerequisites

• you have to create a Slack application, and install it into your workspace - the application should have at least the following scope: users.profile:write.

  optionally, you could also enable chat:write and reactions:write

• to run custom AFK commands from the client, you'll need to enable the agent to control your Mac (from "Privacy and Security" system settings)

Configuration

The first time the agent is run, a ~/.afk.json file is created.

This is the default file created:

{
  "version": 1,
  "token": "",
  "status_text": "I need a break",
  "status_emoji": ":coffee:",
  "channel": null,
  "away_message": "I'm going to take a coffee break",
  "back_message": "I'm back",
  "delay_for_reaction_emoji": 60,
  "back_emoji": "back",
  "agent_emoji": "robot_face",
  "agent_active_start_time": null,
  "agent_active_end_time": null,
  "actions": [
    {
      "action": "lunch",
      "status_text": "Lunch break",
      "status_emoji": ":spaghetti:",
      "away_message": "I'm going to take the lunch break",
      "back_message": "I'm back and stuffed!",
      "command": "lock"
    }
  ]
}

The most important key is token, which must contain the Slack User OAuth Token.

Other settings

status_text

Status to be set when locking the screen

status_emoji

emoji to be set when locking the screen

channel

use this only if you want to write messages on a channel when going AFK and be back.

Put the channel id there. You can find it by right-clicking on the channel and clicking "View channel details". It will be at the very bottom of the popup.

away_message

message to send when going AFK

back_message

message to send when back to keyboard

delay_for_reaction_emoji

in case you will be back before this amount of seconds, do not send a back message, but just react to your away message using a reaction emoji. This will reduce noise in case of quick lock/unlock screen

back_emoji

emoji to be used for quick back reaction

agent_emoji

automatically adds this emoji at the end of every message sent or slack status set. This helps others to know there's a bot that is acting for you.

delay_after_screen_lock

before starting interacting with Slack, wait this amount of seconds.

This will delay reactions to your lock screen status a while, so no Slack commands will be run if you unlock the screen before this time. As example: you are reading a document and the screen locks for inactivity, but you are not AFK.

agent_active_start_time and agent_active_end_time

time range inside which agent is effectively working.

When provided (in the format as HH:MM), the agent will only effectively works when current time is inside this (potentially open) time range. This can be used to disable the agent when using your computer outside working hours.

This is not applied to explicit actions (afk <command>).

Custom actions

The JSON configuration can contain an actions key, with an array of custom actions.

Custom actions can be sent to the agent using the client component:

afk lunch

A custom action is a way to perform something more than the standard lock/unlock monitor.

See the afk command line help for more.

An action interact with Slack in the same way the agent does, and inherit the same configuration, but it can override some of them like: status_text, status_emoji, away_message and back_message. Every of these settings can be null to explicitly inherit from the global settings. back_message can also be false: this disables the back message for the action even if the global setting has a value.

Finally, a custom action can perform one of the following commands:

lock

Lock the screen manually

sleep

Put you computer to sleep
