Introduction
A few months ago I wrote an open-source eBook on how to get started with Bash Scripting.
This is when I came across a tool called Ibis created by Mohamed Said who is a Developer at Laravel.
Ibis allows you to generate an awesome PDF for your eBook, and you can just use markdown!
In this tutorial, I will show you how to get started with Ibis and write that eBook that you have always been planning to write!
Prerequisites
You need to have Composer installed, if you don't have it yet, you can follow the steps here:
Installation
In order to install Ibis, all that you need to do is run the following composer command:
composer global require themsaid/ibis
After the installation, you can test if the ibis command is available with the following:
ibis -V
Once you are sure that you have the Ibis command line tool installed, you can instantiate a new project with the following command:
ibis init
Note: Make sure to run the command in an empty directory where you would store your Markdown files later on
The init command will generate the following files:
/assets
/assets/fonts
/assets/cover.jpg
/assets/theme-light.html
/assets/theme-dark.html
/content
/ibis.php
You can modify the /assets/theme-light.html and the /assets/theme-dark.html to change any of the styles for the eBook. For example, I like to increase the size of the text and the line spacing a little bit.
Configuration
In order to configure ibis all that you need to do is change the values in the ibis.php file.
The main settings would be:
-
title: The title of your eBook -
author: Your anme -
sample: Page ranges to be used with the sample command -
sample_notice: A notice printed at the final page of a generated sample
Creating a cover photo
There is an awesome tool that you could use for free to generate your cover photo:
If you ever need to create a graphic, poster, invitation, logo, presentation – or anything that looks good — give Canva a go!
To change the cover photo, just substitute the default /assets/cover.jpg with your image!
Markdown files
With the above, you can then start writing your eBook! The content would be stored in the content folder where you will have to add your Markdown files.
Ibis would read all of the .md files in the content folder and would use all h1 titles as the name of the chapters.
If you are not familiar with Markdown, make sure to check out this guide here.
Building the PDF
Once you have your content ready, in order to build the PDF of your eBook, just use the following commands
- Light mode
ibis build
- Dark mode
ibis build dark
If you want to generate a sample of your eBook use the following commands:
- Light mode sample:
ibis sample
- Dark mode sample:
ibis sample dark
Once you run the command, it will generate your PDF and store them in the export folder.
The output that you will see would look like this:
==> Preparing Export Directory ...
==> Parsing Markdown ...
==> Adding Book Cover ...
==> Building PDF ...
==> Writing PDF To Disk ...
✨✨ 34 PDF pages ✨✨
Book Built Successfully!
