The Latex to LSC Compiler
This page explains how to write Contextul LSCs (Con-LSC) in Latex, compile them into PlayGo LSC instances, and finally execute them.
In nutshell, these are the required steps:
- Download the PlayGo Environment.
- Add Latex Con-LSCs to LSC.tex.
- Execute the Latex2PlayGo compiler.
- Import the compiled file in PlayGo and execute it.

The PlayGo Environment
First you need to download (here) a PlayGo version that includes a template project and the Latex2PlayGo compiler.
After extracting the zip file you will find the following directory structure (the structure includes only directories relevant to this tutorial). Directories are marked with (D) and files with (F):
Executin playgo.exe will start PlayGo.

Latex Con-LSC
The Latex Con-LSC Language
Our group has developed a dedicated Latex package for easily creating diagrams with a simple textual notation, and presenting them graphically.
The package, called pgf-playgo-lsc, is built upon the pgf[1] and pgf-uml[2] packages. The package imlements only part of the PlayGo LSC idioms. The complete list of the supported idioms in Latex Con-LSC is given in the Latex Con-LSC package. The language semantics is defined in the PlayGo userguide, except for the context idioms that are given in the paper.
We present here a short example for creating an LSC chart using pgf-playgo-lsc:
| \begin{LSCnameddiagram} [title width=p{65px}] {Turn lights off when motion has stopped} \newlifeline {light} {light} \newlifeline {office} {office} \newlifeline {sensor} {mSensor} \coldmonitor {sensor} {motionStopped()} {office} \hotexecute {office} {setOff()} {light} \end{LSCnameddiagram}

The Latex2PlayGo Compiler
The Latex2PlayGo Compiler takes the Latex charts given in the LSC.tex file and compiles them to a PlayGo LSC file named GeneratedLSC.lsc.

Preparing the PlayGo Project
Before we can execcute the generated LSCs, we need to prepare the project:
