Description

The nxtlatex package provides LaTeX tools for the faculty NXT Nachhaltigkeit und Technologie (Sustainability and Technology) at Reutlingen University, Germany. It comprises three components:

• nxtthesis – A thesis class based on KOMA-Script scrreprt. Requires LuaLaTeX. Provides a title page with institution metadata, font options (TeX Gyre, Libertinus), and a standard declaration of independent work.

• nxtbrief – A letter-class option (LCO) for KOMA-Script scrlttr2. Supports pdfLaTeX, XeLaTeX, and LuaLaTeX. Uses the Segoe UI font family.

• beamerthemenxt – A Beamer presentation theme in the NXT corporate design. Requires LuaLaTeX and the Segoe UI font.

In addition, the OpenType font NXT_Logo.otf is included, which provides the NXT logo as a typographic glyph.

Files

Installation

Run

latex nxtlatex.ins

to generate nxtthesis.cls, nxtbrief.lco, and beamerthemenxt.sty. Copy these files together with NXT_Logo.otf into a directory where TeX can find them, e.g.:

~/texmf/tex/latex/nxtlatex/

Then run texhash (or mktexlsr) to update the TeX file database.

Logo files

The NXT and Reutlingen University logo files are protected by copyright and cannot be distributed as part of a public LaTeX package. They are therefore not included in nxtlatex and must be obtained separately.

The package provides installer scripts that download the logos from the university website and place them in your local texmf tree:

macOS / Linux:

sh getnxtlogos

Installs to ~/Library/texmf/tex/latex/nxtlatex (macOS) or ~/texmf/tex/latex/nxtlatex (Linux).

Windows (PowerShell):

powershell -ExecutionPolicy Bypass -File getnxtlogos.ps1

Installs to %USERPROFILE%\texmf\tex\latex\nxtlatex (TeX Live and MiKTeX).

Both scripts call mktexlsr (or initexmf on MiKTeX) afterwards to update the TeX file database. If the logo files are missing, all logo macros (\nxtlogo, \nxthsrtlogo, etc.) are silently ignored and the document still compiles without errors.

The following macros are provided by nxtlatexlogos.sty and are available in all three components:

All macros accept an optional argument passed to \includegraphics, e.g. \nxtlogo[width=4cm].

Customisation

The nxtbrief and beamerthemenxt components are designed for Reutlingen University's NXT faculty but can be adapted for other institutions:

• In nxtbrief.lco, update \setkomavar{backaddress} and \setkomavar{location} with your institution's details.
• In beamerthemenxt.sty, redefine \nxtBeamerSkyline and \nxtBeamerUniversityLogo to point to your own graphics:

\renewcommand{\nxtBeamerSkyline}{my-skyline.pdf}
\renewcommand{\nxtBeamerUniversityLogo}{my-logo.pdf}

• Missing graphics files are silently ignored.
• In nxtthesis, redefine \fakultaet and \hochschule.

Building the documentation

pdflatex nxtlatex.dtx
makeindex -s gind.ist nxtlatex.idx
makeindex -s gglo.ist -o nxtlatex.gls nxtlatex.glo
pdflatex nxtlatex.dtx
pdflatex nxtlatex.dtx

Or simply run make (see Makefile).
