# onPoint

## Installation

This program is meant to be used as a git submodule of your actual presentation project, therefore you need to add it:

```sh
git submodule add -b release git@path-to-onpoint.git
````

Make sure to have python3 and pandoc (the same version for all developers!) installed.
Next, we can install all requirements:

```sh
python3 -m venv venv
source venv/bin/activate
cd onpoint
pip3 install -r requirements.txt
```

## The Project Structure

We recommend you to structure your project directory like this:

	├── images
	├── layouts
	│   ├── default.html
	│   ├── root.html
	│   └── titlepage.html
	├── meta.yml
	├── legal.yml
	├── onpoint
	│   ├── autocompile.sh
	│   ├── main.py
	│   ├── ….py
	│   ├── README.md
	│   └── requirements.txt
	├── slides
	│   ├── chapter1.de.md
	│   ├── chapter1.en.md
	│   ├── chapter2.de.md
	│   └── chapter2.en.md
	├── slides.de.html
	├── slides.en.html
	├── slides.yml
	└── styles
      └── style.css

* `onpoint` is where this program lives.
* In `layouts`, you can create custom templates for your slides.
* `meta.yml` is there to add language-specific meta information (like title internationalization).
* `legal.yml` contains links to the privacy policy and imprint that ought to be rendered into the help menu.
* `slides.yml` will contain a list of all chapters to be included. Their content is expected to live in files inside the `slides` folder.
* You can store your usual web resources in the folders `styles` and `images`.

## Updating onPoint

In order to update the version of onPoint in an existing project, simply enter the `onpoint` directory and run `git pull`.

## Auto-compile during Development

You might want to have all slides auto-compiled for you on safe. For this case, we wrote a small bash script that spawns a file watcher to compile your presentation once any markdown file in the slides folder is saved. Simply run `./onpoint/autocompile.sh` from your project root folder.

You will need Python and `inotify-tools` to execute the script.

## Troubleshooting

### `libxml2` and/or `libxslt` development packages missing
