A simple yet colorful template for Beamer slides.

The file example.tex contains a few frames to show how to use it. To compile it, simply clone this repository and type latexmk -pv example. This will generate and open the .pdf file generated. A pre-compiled (by CI) .pdf file can also be found on the release page.

How to use

• Clone this repository somewhere.

• Add the directory of the cloned repository to your $TEXINPUTS environment variable.

  I personally like to do that on a per-project basis using a .envrc file, but this is not required.

• Add the -recorder option to the LaTeX engine that you use. This will ensure that the path to rainbow-beamer.cls is correctly found, therefore that the included fonts and assets will correctly be included in your presentation.

Options

• listings (default = {}): load the listings package, apply the default style, and preload some languages. This option accepts a comma-separated list of entries of the form language-name[=file-name] where

  • language-name is the name of the language to be used in the lstlisting environment. When language-name contains square brackets (for example for language flavors), it may be needed to enclose it in curly brackets.
  • file-name is an optional .sty file (without the extension!) that must be loaded to use the language-name in the lstlisting environment.

• fonts/main, fonts/sans, fonts/mono, fonts/math are font names (all default to {}) to be used instead of the default ones.

  You can set all these (in the class options) either one by one like

  fonts/main=...,
  fonts/sans=...,
  fonts/mono=...,
  fonts/math=...
  

  or all at once like

  fonts={
    main=...,
    sans=...,
    mono=...,
    math=...
  }
  

  Note that you do not necessarily have to set each. You may choose individual aspects to customize (e.g. only the monospace font).

  For more complex customization of fonts (e.g. specifying a bold font to be used), you may pass values of the form[fontspec-options...]{...} (necessarily surrounded by braces {}).

• withappendix[=true|false] (default = false) redefines the \appendix command to automatically number the appendix frames with letters instead of numbers, and removes them from the total frame count.
