# Trigon theme

![Pipeline status](https://gitlab.com/thlamb/beamertheme-trigon/badges/master/pipeline.svg)

_A modern, elegant and versatile theme for Beamer._

[![Demo][demo-shield]][demo-url]
[![Documentation][docs-shield]][docs-url]

**Trigon** found its origin and inspiration in the graphical guidelines
resulting from the visual identity overhaul of the [University of
Liège](https://www.uliege.be/cms/c_9247131/en/a-new-visual-identity).
Although directly inspired from these guidelines, the theme was stripped out of
any mention or specificities related the University and its faculties. This
makes the **Trigon** theme perfectly suitable for many different contexts.

The final product provides a modern, elegant and versatile theme with a
high degree of customization.
The main design focuses on triangular shapes for major layout elements and noise
minimization for the main body of the work.

The theme is now available on [CTAN](https://ctan.org/pkg/beamertheme-trigon)
and will be shared as a template on [Overleaf](https://www.overleaf.com)
shortly.

Feature requests, issues and pull requests are welcome.

## Features

- Multiple style variations for title, section and regular slides
- Dark theme
- Many convenient options (numbering style, toggle section slides, title font changes,...)
- Looks better on 16:9 format, but supports 4:3 as well
- Lightweight (does not require lots of additional packages)
- Similar options than with [Metropolis theme](https://github.com/matze/mtheme)

## Note

- This theme works best using the `sourcesanspro` font package, which is loaded
  by default. As some users may not want to load additional packages or want to
  use other fonts, the package can be disabled using the option
  `usesourcefonts=false`.

## Installation
To install a stable version of this theme, please refer to update instructions
of your TeX distribution. Trigon has been on
[CTAN](https://ctan.org/pkg/beamertheme-trigon) since March 2021. For users of
typical TeX distributions (TexLive, MacTeX, MikTeX), simply updating your
package list should install trigon on your system.

If you want to use the cutting-edge development version of Trigon, you can
install it manually by following these steps:
1. **Download the source** using a `git clone` of the [Trigon
   repository](https://gitlab.com/thlamb/beamertheme-trigon) or as a [zip
   archive](https://gitlab.com/thlamb/beamertheme-trigon/-/archive/master/beamertheme-trigon-master.zip)
2. **Compile the style files** by running `make sty` inside the downloaded
   directory. (Or run LaTeX directly on `source/trigontheme.ins`.)
3. **Move the resulting `*.sty` files** to the folder containing your
   presentation. To use Trigon with many presentations, run `make install` or
   move the `*.sty` files to a folder in your TeX path instead.
4. **Use the theme** by declaring `\usetheme{trigon}` in the preamble of your
   document.

### Overleaf
Trigon is not yet included in default TexLive installations. Therefore, it is
not natively available on [Overleaf](https://overleaf.com) (it should be
included at the end of Q3 2021). In the meantime, a template project was made
and will be kept updated with the current master version. To use it, follow
[this link](https://www.overleaf.com/read/dvbnhdcbfknk), copy the project
(menu/copy project) and modify it to your needs.

Once the theme will be properly included to Overleaf, a basic template will be
added to the Overleaf theme gallery.


## Usage
See [the package documentation][docs-url] for a detailed view of the package
options.

## Contributing

All contributions to this theme are welcomed, whereas in the form of issue
report, feature requests or pull requests.

If you want to propose an interesting alternative layout for this theme (for
the title, section or regular slides), please make sure to respect the
following criteria:
- Maximum three main triangles on the layout
- Blending type "multiply" for overlapping triangles
- Triangles must all be equilateral (60° angles), some useful macros are
    defined in _beamerinnerthemettrigon.dtx_ for that

## References & Acknowledgment

- The theme structure and options are heavily based on the [Metropolis
  theme](https://github.com/matze/mtheme)
