## What is Gotham ?
This `Gotham` package is a modern, minimal-ish, versatile and extendable theme for your `Beamer` presentations using `LaTeX(3)`.


## Table of Contents
[[_TOC_]]


## Why this package ?
ONCE UPON THE TIME, I was adapting `Metropolis` [Beamer](https://ctan.org/pkg/beamer)  theme to get my institutional templates.
Indeed, `Metropolis` Beamer theme is a great work that is very convenient and well appreciated by many. 

BUT, [`Metropolis`](https://ctan.org/pkg/beamertheme-metropolis) seems not maintained anymore and is not flexible enough.
Moreover, `Metropolis` (or its successor initiative Moloch) and Beamer in some extends are not very flexible. 
For example, it requires cumbersome modifications to apply a different background for your section frames.

SO, `Gotham` tries to bring that kind of flexibility and [`LaTeX3`](https://www.latex-project.org/latex3/) implementation on top of the good-looking `Metropolis` theme.


## Some of the features included
- :gear: `l3build` a build system for LaTeX testing and deployment, etc...
- :hammer_and_wrench: `expl3` compliant
- :first_quarter_moon: dark, light and transparent background
- :movie_camera: can adapt to 16:9 and 4:3 screen format
- :stopwatch: multiple progress bar style
- :shopping_cart: **can mix** themes


## See it in action
Here are some screenshot of what you can obtain:

A deeper taste of how `Gotham` can render is available through the **`pdf` example/demo** that can be found [here](https://gitlab.com/api/v4/projects/52144864/jobs/artifacts/main/raw/gotham-example169transp.pdf?job=deploy-files), and the `tex` source file to build it is available [here](https://gitlab.com/RomainNOEL/beamertheme-gotham/-/blob/main/examples/gotham-example169transp.tex?ref_type=heads).

The following code shows a **minimal example** of a Beamer presentation using Gotham.
```latex
\documentclass{beamer}
\usetheme{gotham}
\title{A minimal example}
\date{\today}
\author{Romain NOEL}
\institute{Centre for Modern Beamer Themes}
\begin{document}
  \maketitle
  \section{First Section}
  \begin{frame}{First Frame}
    Hello, world!
  \end{frame}
\end{document}
```
is yielding the following:

## Documentation
The complete `pdf` documentation can be found through an [artefact](https://gitlab.com/api/v4/projects/52144864/jobs/artifacts/main/raw/gotham.pdf?job=deploy-files).


## How to install ?
Several possibilities are available and tested: 
- download the `.sty` released zip files,
- build from sources using `l3build`,
- download or update from [CTAN](https://ctan.org/pkg/beamertheme-gotham),
- fork a example from [Overleaf](https://overleaf.com) .

### Download from release
The zip file containing the `.sty` files is downloadable through our latest [release link](https://gitlab.com/RomainNOEL/beamertheme-gotham/-/releases/)

### Build from sources
You can also install the theme from sources, in which case you need a working LaTeX installation with `l3build` installed. 
Then just follow these steps:
```bash
git clone https://gitlab.com/RomainNOEL/beamertheme-gotham.git
cd beamertheme-gotham
l3build install
```

Additionally you can use the other `l3build` target:
- `l3build unpack` builds the theme style files.
- `l3build doc` builds this documentation manual and the examples.
- `l3build check` builds the theme and manual.
- `l3build install` installs the theme into your local texmf folder.
- **STOP** unless you want remove it.
- `l3build uninstall` removes the theme from your local texmf folder.
- `l3build clean` removes the files generated by `l3build`.

### Download from CTAN
The CTAN repository is available through the Gotham [package](https://ctan.org/pkg/beamertheme-gotham), so you can install it using your favorite LaTeX package manager. For example, with `tlmgr`:
```bash
tlmgr install beamertheme-gotham
```

### Fork from Overleaf example
If you want to play with it before installing, you can fork this Gotham example on [Overleaf](https://www.overleaf.com/read/ybdcnjxjrwgq#3ae7f9) and have fun. 

If you want to go further and have examples about how to adapt Gotham  to obtain custom theme for your institution, visit this Overleaf example [adaptation](https://www.overleaf.com/read/vxnjgfmyvccj).
