Getting Started

To use this template in a new project, either download the ZIP directly from GitHub or clone it using Git:

git clone git@github.com:fastexitlane/latex-boilerplate.git
# now set up your own Git workspace:
git remote remove origin
git remote add origin git@your-own-gitlab.host:path/to/repo.git
git push origin master

If you already have set up an empty Git workspace for your project, add it as additional remote and then fetch and pull:

git remote add boilerplate git@github.com:fastexitlane/latex-boilerplate.git
git fetch boilerplate
git pull boilerplate master
# if you don't want to keep the remote, remove it:
git remote remove boilerplate

In order to use the preconfigured continuous integration, make sure your GitLab CI meets the Basic Requirements.

If you know what you're doing, simply start adding your content files in chapter/ and \input them in main.tex. If you do not know what you're doing or get into trouble, you may want to read on. ;-)

Basic Structure

The main entry point for the document compilation is the file main.tex in the repo root. Besides setting some common parameters for the document (like author name, title, date etc.), the basic document structure is created here (mostly by including seperate files) in the following order:

• configuration (config.tex)
• title page (additionals/title.tex)
• disclosure notice (additionals/disclosure.tex, decomment in main.tex if neccessary)
• table of contents
• list of acronyms (additionals/acronyms.tex)
• list of figures
• list of tables
• list of code listings
• chapter files (chapter/*, needs to be filled up manually)
• bibliography (additionals/references.tex, using the entries defined in library/library.bib)
• declaration of authorship (additionals/affirmation.tex)

If you don't need one of the predefined document parts or want to omit it, simply remove or comment out the corresponding statements in main.tex.

(i) Please note: Before starting with content, you should change the common variables in main.tex.

Inserting basic content

For each chapter create a single chapter file in the chapter/ directory. Chapter files need to reference the main file using

%!TEX root = ../main.tex

Next, include it in main.tex using

\input{chapter/myfile}
\newpage

Numbering the files with prefixes (like 01_introduction) is recommended.

Bibliography

The bibliography index uses biblatex. Entries are taken from library/library.bib, you may add your PDF files here too and link them to the bibliography entries (e.g. using biblatex frontend/gui tools like JabRef).

To be included in the document, every bibliography entry needs to be keyword-classified manually. For each keyword there will be a seperate subsection in the bibliography section in the document. If there's no bibliography entry for a keyword, the bibliography type will be ommitted and no subsection will be created in the bibliography section in the document.

Here's an overview of the supported document types and their keywords:

type	biblatex document type	keyword
monographs	@Book	-
essays and articles in magazines	@Article	-
articles in collections	@InCollection	-
other papers	@InProceedings or @Thesis	-
web pages	@Online	-
legislative documents	@Misc	jurisdiction
company internal docs	@Misc	company

References within the document are usually done using the \autocite[prefix][postfix]{bibkey} statement. The default citation format is footnote. When referencing within a footnote, please create a manual reference using \cite.

(!) For the references to be syntactically complete and correct, pleae consider the correct document types shown in the table above.

Layout and further configuration

The predefined document layout is the following:

• page size: A4
• borders: left=40mm, right=20mm, top=25mm, bottom=25mm (using geometry)
• Roman page numbering is used for introductory pages; arabic page numbering starts with first content chapter (see main.tex for that)

Further configuration can be done in config/config.tex.

Document Outline

The scrbook document class provides the following elements (in said order) to outlining a document:

• \part{}: roman numbering, e.g. I
• \chapter{}: arabic 1st level numbering, e.g. 1
• \section{}: arabic 2nd level numbering, e.g. 1.1
• \subsection{}: arabic 3rd level numbering, e.g. 1.1.1
• \subsubsection{}: arabic 3rd level numbering, e.g. 1.1.1.1
• \paragraph{}: no numbering and independent from preceding hierarchy elements

Continuous Integration using GitLab CI

The .gitlab-ci.yml file comes preconfigured to spellcheck and compile the LaTex document.

Basic Requirements

If you want to use the preconfigured CI scripts, you need to register a shell runner which basically has the following tools installed:

• latexmk as LaTex build system
• xelatex as LaTex PDF environment
• Python and the Pygments library (for source code listings using the minted environment)
• hunspell for spellchecks

The provided configuration gitlab-ci.yml assumes that you have rununers with the tags hunspell and latex assigned. It's recommended to register at least two runners (they may reside on the same box) in order to parallelize pipelines and speed up builds.

(!) Please adapt the configuration to your own runner setup if neccessary.

Spellchecking

Spellchecking is done using hunspell. As LaTex \input directives are not recognized, all TeX files containing content need to be spellchecked seperately. Therefore, only the chapter files are included in the spellcheck.

If you need certain words to be ignored during spellcheck (e.g. if they're not in the standard dictionaries), please insert them into the file .hunspellignore. This is a simple word list structured by one word per line.

By default, the spellcheck job is allowed to fail.

Building the PDF

The CI pipeline will build main.tex (and everything included here) to PDF using xelatex. It provides better handling of unicode characters and typesets special characters (like german umlauts) more precise.

The build output is generated to main.pdf, which can be downloaded from GitLab coordinator for two days (each pipeline run).

Some special effects...

Lists

Please use \compactitem environment for unordered lists and \compactenum environment for ordered lists. Unlike the usual itemization environments they do not break lines with the usual paragraph spacing (which would be way too much due to the \onehalfspacing).

Images

Resource files for images may be stored in resources/. To reference an image from within the document, use the figure environment:

\begin{figure}[H]
    \centering
    \fbox{\includegraphics[width=0.75\textwidth]{resources/myimage.png}}
    \caption{Caption for my image goes here...}
    \label{fig:myimage}
    \source{source of the image}
\end{figure}

The \label is used to cross-reference the image using \ref.

The \caption may contain a usual \cite directive (see below).

Acronyms

If you introduce acronyms, add them to additionals/acronyms.tex in the following way:

\acro{VMCS}{Virtual Machine Control Structure}

(i) Please note: If you have acronyms that are longer than four characters, you may extend the parameter in brackets behind the \begin{acronym} statement.

Code Listings

Listings (code snippets) are done using the minted environment. It provides syntax highlighting for several languages via an external Python library (Pygments) and has comprehensive layout capabilities. Though, handling of captions is a bit complicated, which is why it's wrapped into a custom code environment:

\begin{code}
    \inputminted{bash}{resources/yoursource.sh}
    \label{yourlabel}
    \captionof{listing}{Some Caption goes here...}
    \source{and you can tell people where you got the code from...}
\end{code}

If you want to provide your source code directly in the LaTex document, replace the \inputminted directive by a whole minted environment:

\begin{code}
    \begin{minted}{bash}
        # your code goes here...
    \end{minted}
    \label{yourlabel}
    \captionof{listing}{Some Caption goes here...}
    \source{and you can tell people where you got the code from...}
\end{code}

Inline code is done using \mintinline{bash}{# your inline snippet}.

The config for syntax highlighting etc. is centrally provided in config/config.tex using the \setminted directive. For changes, see the official docs.

Paragraph Distances and Onehalf Spacing

There are certain LaTex environments that cause huge paragraph distances in combination with the onehalfspacing option (1.5 line height). For that reason you may wrap such environments (e.g. lists, images, tables, paragraphs etc.) with a vspace:

\vspace{-\topsep}

Snippets for working in VS Code

I compiled a few useful editor snippets to work with this boilerplate in VS Code.
