This PHP tool helps you write eBooks in markdown. Run `ibis build` and an eBook will be generated with:
1. A cover photo.
2. Clickable auto-generated table of contents.
3. Code syntax highlighting.
4. Available in 2 themes. Light and dark.
Ibis was used to create [Laravel Queues in Action](https://learn-laravel-queues.com), an eBook I published in August 2020. [Click here](https://learn-laravel-queues.com/laravel-queues-in-action.zip) for the sample.
## Installation
Make sure you have PHP7.3 or above installed on your system and that your gd extension is enabled in your php.ini file.
First, install the composer package globally:
```
composer global require themsaid/ibis
```
Then, run this command inside an empty directory:
```
ibis init
```
This will create the following files and directories:
- /assets
- /assets/fonts
- /assets/cover.jpg
- /assets/theme-light.html
- /assets/theme-dark.html
- /content
- /ibis.php
You may configure your book by editing the `/ibis.php` configuration file.
## Writing Your eBook
The `init` command will create sample .md files inside the content folder. You can explore those files to see how you can write your book. This sample content is taken from [Laravel Queues in Action](https://learn-laravel-queues.com).
Inside the content directory, you can write multiple `.md` files. Ibis uses the headings to divide the book into parts and chapters:
```
# Part 1
tags define the start of a part. A separate PDF page will be generated to print the part title and any content below.
## Chapter 1
tags define the start of a chapter. A chapter starts on a new page always.
### Starting with Ibis
tags define different titles inside a chapter.
```
### Adding different quotes
Three different types of quotes can be added: `quote`, `warning`, and `notice`.
```md
>{quote} This is a quote.
>{warning} This is a warning.
>{notice} This is a notice.
```
### Using images
Images can be stored in the content folder and then brought in like this:
```
```
### Adding a cover image
To use a cover image, add a `cover.jpg` in the `assets/` directory (or a `cover.html` file if you'd prefer a HTML-based cover page). If you don't want a cover image, delete these files.
## Using Fonts
Edit your `/ibis.php` configuration files to define the font files to be loaded from the `/assets/fonts` directory. After that you may use the defined fonts in your themes (`/assets/theme-light.html` & `/assets/theme-dark.html`).
## Generating PDF eBook
```
ibis build
```
Ibis will parse the files in alphabetical order and store the PDF file in `/export`.
The default is to generate the PDF using the light theme, to generate a PDF using the dark theme:
```
ibis build dark
```
## Generating A Sample
```
ibis sample
ibis sample dark
```
This command will use the generated files from the `ibis build` command to generate samples from your PDF eBook. You can configure which pages to include in the sample by updating the `/ibis.php` file.
## Development
This project uses PHP CS Fixer with a code standard defined in `.php_cs`.
To review code out of style, you can run the fix command as a dry run. Run the composer script like this:
`composer run csfix-review`
To fix the source code, run the following composer script:
`composer run csfix`
