The argumentation LaTeX Package

A LaTeX package for drawing argumentation frameworks (AFs) via TikZ. It provides a simple, high-level syntax for creating argument nodes and attack/support edges while retaining full TikZ compatibility and customisation options.

Features

• af environment for creating labelled, referenceable argumentation frameworks
• Commands for attacks (\attack, \dualattack, \selfattack), supports (\support), and annotated edges
• Collective (hyperedge) attacks and supports via \setattack and \setsupport
• Five argument styles, three attack styles, and three support styles
• Size presets (small, tiny) for two-column layouts
• Automatic or manual argument indexing
• Full beamer overlay support for presentations
• Additional macros for consistent AF naming and referencing (macros option)

Installation

The package is available on CTAN and is included in TeX Live and MiKTeX, so no manual installation is needed - simply load it in your preamble:

\usepackage{argumentation}

Alternatively, you can place argumentation.sty in the same directory as your .tex file to use it locally.

Quick Start

\usepackage[namestyle=math]{argumentation}

\begin{af}
    \argument{a}
    \argument[right=of a1]{b}
    \argument[right=of a2]{c}

    \attack{a1}{a2}
    \dualattack{a2}{a3}
    \support{a1}{a3}
\end{af}

Arguments are automatically assigned identifiers a1, a2, a3, ... in order of creation. Relative positioning (right=of, below=of, etc.) and absolute positioning (at (x,y)) are both supported.
