??? What is Lua all about

“Lua is a powerful, fast, lightweight, embeddable scripting language.”

http://www.lua.org/about.html

Extending C/C++ applications with a configuration / scripting engine.

Rationale

Extending C/C++ applications with a configuration / scripting engine.

Rationale

•  Based on a virtual machine •  Can load source code / read char streams •  And compile it to portable bytecode

Extending C/C++ applications with a configuration / scripting engine.

Rationale

•  Tiny core (150kB) •  Pure ANSI C •  Simple C API

Extending C/C++ applications with a configuration / scripting engine.

Rationale

•  DSL building kit •  Provides only basic features •  And a powerful runtime

Gaining momentum

??? What is Missing

IDE Support

http://www.eclipse.org/koneki/ldt/

LDT

A tool that follows Lua’s philosophy

Providing lot’s of modern features while remaining easily embeddable in larger systems.

Rationale

 Lua strengths Dynamic Embeddable

 are double-edged swords

 that make tooling support tedious.

However

Editor VS

Dynamic Code

Debugger VS

Embedded Application

LDT Typical Use Case

Sierra Developer Studio

 Sierra’s IDE for ALEOS Embedded Application Framework

??? What’s Next

LDT Roadmap  Working with local interpreters

 Add launch configuration

 Supporting OOP

 Management of require

 Improvement of content-assist and scoping
