# About 

This project is an experiment of how to generate the WTF handbook in various output formats (HTML, epub and pdf) from the [git repository for the WTF handbook](https://git.wtf-eg.de/wtf-eg/handbuch). The handbuch sources are included as git submodule.

This repository contains the [Sphinx](https://www.sphinx-doc.org/) configuration and a Sphinx theme adapted for the [corporate identity of WTF cooperation](https://git.wtf-eg.de/ag_kommunikation/wtf_propaganda).


# How to build

### Checkout with submodules

This repository accesses the required WTF handbook's content as a git submodule. Therefore, make sure to check out this repository including its submodule:

```
git clone --recurse-submodules https://git.wtf-eg.de/wtf-eg/handbuch-gen.git
```

If you cloned this repository initially without submobules, you can always update the content of submodule directories with the git submodule update command. Execute the command from the main project directory:

```
git submodule update --init --recursive
```

The --init flag initializes the submodules before the update. The --recursive option searches for nested submodules and ensures they are updated too.

### Python based dependencies

In order to generate the documentation, first create a Python 3 virtual environment using the `venv` module included in Python 3:

1. Create a virtual Python environment in the directory `venv`: ```python3 -m venv venv```
1. Activate the virtual Python environment: ```source venv/bin/activate```
1. Install the packages listed in [requirements.txt](./requirements.txt) using `pip`: ```pip install -r requirements.txt```

### Other dependencies

For generating the images from PlantUML sources (`*.plantuml`), [PlantUML](https://plantuml.com/) is required.

For pdf output the LaTeX builder is used, so `latex` and `pdflatex` need to be installed. On a clean (no Latex compilation yet) operating system like GNU/Debian, the following dependencies are required to make Latex compile the sources.

```
sudo apt install texlive-base texlive-latex-base texlive-latex-extra texlive-lang-german texlive-fonts-extra --no-install-recommends
```

For document generation `make` and latexmk` is required.

### Running the document generation via make

The top level directory contains a Makefile, for generation with all output formats use

`````
make bundle
`````

The output files of the final handbook can be found in the subfolder `./bundle`.

All generated intermediate artifacts and the final output files can be found in the `./build` subfolder.

### Clean up

1. Deactivate the virtual Python environment: ```deactivate```
2. Clean up the build sources: ```make clean``` and ```rm -r build bundle```
