The tango LaTeX document class, v0.7.1

On Monday July 8, 2024, I submitted a very first version (0.7.1) of the tango class for LaTeX (tango.cls file) to the CTAN network. Of course, a few kind testers had the first look at the development versions, and I’d like to thank them here.

In alphabetical order, and hoping I haven’t forgotten anyone:

Cyprien Accard;
Delphine and Philippe Arzoumanian;
Jean-Yves Baudais;
Denis Bitouzé;
Thierry Bouche (who provided a strict but constructive critique of the first mock-up);
Laurent Chéno;
Daniel Flipo (who helped me a lot with multilingual issues);
As well as a few members of the “Olympiades Mathématiques de 1re” team from the Orléans-Tours educational district.

What the Tango class is

Tango is a LaTeX document class (\documentclass[]tango) for mathematics teachers. The tango class requires lualatex, a few particular packages (see full documentation for details) and a recent version of LaTeX (see 4 below).

1. Version

The number of this first public release is 0.7.1.

2. License

Latex public project licence (LPPL), version 1.3c

3. Installation

If you need to install tango “by hand”, simply place the tango.cls file in the latex directory of one of your texmf trees. For example:

TEXMF/tex/latex/tango/tango.cls

Note, however, that the tango class is now part of the texlive 2024 distribution and will be installed as part of an update. I don’t know what’s happening with MikTeX (if you do, I’d like to hear about it).

4 Use

documentclass[<options>]{tango}
The tango class requires recent versions of LaTeX and lualatex. At my home, everything works on TeXLive 2024, TeXLive 2023 and the latest update of TeXLive 2022.

5 About examples

Tango comes with an Examples directory. The files provided allow you to test the tango class and understand how to adapt margins, headers, etc. On TeXLive, this directory is located in

texmf-dist/doc/latex/tango/`

The files to be compiled (with lualatex, but this is normally guaranteed by the first line of the file for those using a shell dedicated to TeX).

book-mathematics.tex
handout-euler.tex
handout-polynomes-deg2.tex
schoolwork.tex
candide.tex (the result is designed to be viewed in two-page mode).

To go further

To go further, the easiest way is to try it out, either by updating your installation first, or by retrieving all the files (or just the documentation) from CTAN.

The CTAN network is now so powerful that I see no point in distributing tango here (if you have any particular problems, please don’t hesitate to contact me). I only provide one of the examples as an attachment, without its source files.
