kvdefinekeys

Provides specialized functionality for defining and managing key-value pairs in LaTeX document customization and package configuration.

Overview

Offers a streamlined approach to key-value pair management, particularly when working with package options and document configurations. The package serves as a bridge between key definition and processing systems, making it easier to create and manage customizable document parameters.

Implements specialized key definition mechanisms compatible with the kvsetkeys processing system.
Particularly useful for package authors developing customizable LaTeX packages.
Simplifies the creation of flexible, configuration-based document interfaces.
Often used in conjunction with other key-value processing packages for enhanced functionality.

Getting Started

To use kvdefinekeys, include it in your document preamble:

\documentclass{article}
\usepackage{kvdefinekeys}

This package is primarily intended for package authors. The main functionality is:

% Define keys for a package
\kv@define@key{family}{keyname}{code}

Examples

Basic usage of kvdefinekeys to define and set custom key-value pairs.

\documentclass{article}
\usepackage{kvdefinekeys}
\usepackage{kvsetkeys}

% Define a family of keys
\makeatletter
\newcommand{\setupdemo}[1]{%
  \kvsetkeys{demo}{#1}%
}

% Define keys in the 'demo' family
\kv@define@key{demo}{color}{\def\democolor{#1}}
\kv@define@key{demo}{size}{\def\demosize{#1}}
\kv@define@key{demo}{style}{\def\demostyle{#1}}

% Set default values
\setupdemo{color=black,size=normal,style=plain}
\makeatother

\begin{document}

% Initial values
Current settings: color=\democolor, size=\demosize, style=\demostyle

% Change settings
\setupdemo{color=red,style=bold}

Updated settings: color=\democolor, size=\demosize, style=\demostyle

% Change more settings
\setupdemo{size=large}

Final settings: color=\democolor, size=\demosize, style=\demostyle

\end{document}
