C++ Implementing scripting (Repeatable Actions)

Question

I have a desktop app written in C++. It does a variety of different things and interacts with a database. I have made most actions that need to be performed selectable from a list. Actions are performed serially on data sets and need to be saved and played back at a later time on a different result set.

The actions are typically performed from a drop down menus and there are no load/save to disk operations. I dont' necessarily need scripting capability, but if thats the easiest way to go that's fine.

How would you approach this?

Added, This application is NOT written in OOP style

Answer 1

Lua

It's a great, simple scripting language, easily embedded into your apps.

Answer 2

Sounds like the GoF Command design pattern:

Answer 3

• lua with LuaBind is quite widely used
• Python with boost::python is also widely used but heavier on space

Now I know less know scripting languages that are useful in game programming, so useful in whatever application you need scripting for:

• Falcon : the more versatile and flexible solution I know and use
• ChaiScript : the easier to integrate I know
• AngelScript : didn't try yet
• GameMonkey : didn't try yet
• IO : didn't try yet
