S-Lang Module Reference (version 2.3): Introduction

1. Introduction

This document describes the functions that are available via the modules that are distributed with the S-Lang library. A more complete list of modules may be found at http://www.jedsoft.org/slang/modules/.

To utilize the functions in a model, the module must be loaded into the interpreter. This is most easily accomplished via the require function. For example, the png module may be loaded using:


   require ("png");

Sometimes it is desireable to load the module's functions into a separate namespace to avoid collisions, e.g.,


   require ("png", "PNG");

Then the png_read function may be called using PNG->png_read.
