Do you want to check the weather? Roll a die? Need text-to-speech or just want to have some fun? This is the bot for you!

Set up your own instance by following the step-by-step instructions in the installation guide.

Commands

Legend for the following guide:

  • # highlights the command in the list of commands
  • | serves as a separator between commands, to be understood as OR
  • <...> indicates the need to insert a specific type of data
  • [...] is used for optional arguments
  • > represents the concept of the executed command
  • ! is for comments

You don't need to include these symbols in the command; they are only used as markdown for this guide. Therefore, if, for example, you want to execute the command to clean a link, just type clr , and not # clr, or in the case without JavaScript, clr -js.

Installation

Preamble

As a first step, it is necessary to generate the files that will contain the information required for the correct operation of the bot. When possible, the required software will also be installed, as listed at the end of the README. Below you will find a guide for Linux users and a guide for Windows users. Regardless of your operating system, the execution should be successful; if not, feel free to open an issue.

Linux

  • Make sure you have wget installed (run wget --version)
  • In the main folder, you will find preamble.sh
  • Execute chmod 755 preamble.sh
  • Then run ./preamble.sh to download the necessary files

Windows

Note: In addition to the required software Chocolatey will also be installed.

  • Open a PowerShell terminal as an administrator
  • Remember that you may need to run Set-ExecutionPolicy RemoteSigned
  • In the main folder, you will find preamble.ps1
  • Execute .\preamble.ps1 to download the necessary files and install the required dependencies

Key generation

  • Register on OpenWeatherMap and obtain a free API key
  • Generate a key for a Telegram bot by contacting @BotFather
  • Go into the subfolder ./orders/utility and modify the secrets file
  • The first line of the file should be the OpenWeatherMap key
  • The second line of the file should be the Telegram key
  • Leave an empty line at the end as per the standard so that running cat secrets does not have an extra newline but also doesn't cause the terminal line to wrap
  • For example, the file should look like this:
OWM-KEY
TELEGRAM-KEY
  • The cat secrets command should then display the following:
[user@machine]:~/TelegramBot/orders/utility $ cat secrets
OWM-KEY
TELEGRAM-KEY
[user@machine]:~/TelegramBot/orders/utility $

Note: It may not be necessary to insert an empty line at the end of the text; it depends on many factors. However, remember this convention for the following steps as it is essential for the correct reading and writing of files.

Populate administrative files

  • Go into the subfolder ./orders/utility and modify the superadmins file
  • Insert your Telegram user ID following the previous text formatting convention
  • If you don't know your Telegram user ID, you can write a short line of code inside bot.py to print your user ID, as follows:
# You can find this function inside bot.py and write it at the first line
async def msg_filter( ... ):
    print(update.effective_chat.id)
  • Now, send a message to the bot privately, and it will print your ID to the terminal. Alternatively, you can contact a bot like @userinfobot (I haven't tested it, but it's commonly suggested)
  • Once you have obtained your ID and added it to superadmins, add your ID to admins as well, following the convention
  • If you want to allow other users to use your bot, you can do so by adding the bot to a group with the interested user and by typing manuser add in response to a message from the user you want to promote

Python dependencies

  • The bot has been programmed with Python 3.9.2
  • Install the requirements found in requirements.txt
  • Execute pip install "python-telegram-bot[job-queue]"
  • Execute pip install "python-telegram-bot[http2]"

Other dependencies to install

Below is the list of software necessary to use the bot commands, all installable from the command line. Depending on the OS, some of them are already installed.

Linux

Windows

Execution

You can run the bot by executing python bot.py from the terminal. Alternatively, if you want the bot to start on machine startup (on Linux), type crontab -e and insert the following text string:

@reboot python ~/your_path/TelegramBot/bot.py > ~/your_path/TelegramBot/out 2>&1
