You can control external codes and use their results from Smile. To that effect, three mechanisms are available.

• you can use your code strictly as it is and control it through the UNIX shell,
• you can make it into a Scripting addition and provide it with an English-like dictionary,
• or you can re-package it into a scriptable application.

The latest is more work but it allows your scripts to interact with the code in real-time.

See more details about each option in the chapters below.

• Using a UNIX executable
• Making a code into an osax
• Making a code scriptable
• The XCode projects
