How do I pass two parameters to a tikz style? I would like to do something like this:

\begin{tikzpicture}[
    transformer/.style={draw, cylinder, gray!80, rotate=90, minimum height=#1, minimum width=#2},

And then, I want to use this style in a node:

\node [transformer{2.3cm}{1cm}] () at (0,0.6) {};

Use style 2 args, see page 493 of the manual (sorry, I'm currently to lazy to write and test a complete answer). –  Caramdir Jun 22 '11 at 19:02
    
@Caramdir: Thanks for the link. Much appreciated — absolutely no need to apologize. –  Neil G Jun 22 '11 at 19:04

I think you have to use something like [transformer={2.3cm}{1cm}] –  Peter Grill Jun 22 '11 at 19:04

\documentclass{article}
\usepackage{tikz} 
\usetikzlibrary{shapes}  
\begin{document}
 \thispagestyle{empty} 

 \begin{tikzpicture}[
    transformer/.style 2 args={draw, cylinder, gray!80, rotate=90, minimum height=#1, minimum width=#2}]

\node [transformer={2.3cm}{1cm}] () at (0,0.6) {};
\end{tikzpicture}  
\end{document}

Indeed, there is also .style n args={<number of args>}{<style>} for more arguments and .style args={<parameter text>}{<style>} which allows to define the arguments using a parameter text like \def does. –  Martin Scharrer Jun 22 '11 at 21:04
