}
  • Compile the translation files using the following command: 

    make i18n-compile

Setting up the bot

Before all, clone this repository.

Using Docker

  • Simply, run the following command:

docker-compose up --build -d

Without Docker [NOT RECOMMENDED]

Python dependencies

It requires Python 3.7 with pip v19+ installed or poetry if you use it.

Clone the repository and run any of the following commands:

Using poetry

poetry install

Using Pip

pip install .

Database

The bot depends on sqlite database. Make sure that your system has it installed.

Other requirements

You can go through the Dockerfile to see how the bot requirements are being installed.

  • The conversion process is done by utilizing Calibre and its ebook-convert, so make sure you have it installed.
  • To convert from and to KFX, you need to install KFX Input and KFX Output plugins in calibre, this can be done from the command line by using the following commands: 

    # KFX Input
wget https://plugins.calibre-ebook.com/291290.zip 
calibre-customize -a 291290.zip
# KFX Output
wget https://plugins.calibre-ebook.com/272407.zip
calibre-customize -a 272407.zip
  • Also, KFX Output plugin requires Kindle Previewer 3, which can run on linux under Wine.

Running the bot

If you finally managed to get all pieces in its place without using docker, run the bot using:

python3 -m ebook_converter_bot

Internationalization (i18n)

The bot uses gettext for internationalization and makefile for running i18n tasks easily.

  • First, generate .pot template using make i18n-generate-messages.
  • Update the current translation files using make i18n-merge, then edit the translation strings.
  • Compile the translation files using make i18n-compile.

To add a new language to the bot, run the following command (change ‘ar’ to your language code) then edit the new language file with translation and compile.

LANG=ar make i18n-init-lang
