Wartbed:Architecture/Scripting
From Dark Omen Wiki
As of yet, there is no need for scripting.
Options for script languages include
| Script language | Notes | Maturity | Embeddability | Ease of using from C++ | Language complexity | Script parsing/execution | Platforms | Licence |
|---|---|---|---|---|---|---|---|---|
| LUA | Designed for C for maximum portability. Some hoops (local wrappers) must be hopped for C++ integrations. | Well done | High | Easy | Medium. Sparse semantics. Procedural and OO paradigms. Vanilla but not particularly aesthetic syntax. | Fast | Most | |
| AngelScript | No notes yet | Medium rare | High | ??? | ??? | Fast? | ??? | |
| Ruby | No notes yet | Well done | Cumbersome? | Lowest | Higher. Single-paradigm, extreme OO design. CLosures, lambda, mix-ins. Very appealing and human-readable semantics and syntax. | Slower | All? | |
| Python | No notes yet | Well done | ??? | Low | High. The German of script languages: extremely well equipped libraries, has everything you'll ever need, but can be butt ugly. | Slow | All | |
| Minimal | Git download location | Rare | ??? | ??? | ??? | ??? | ??? | |
| Falcon Programming Language | Designed for maximum speed using C++. | Medium rare | High | ??? | High: Multi-paradigm: supports procedural, object oriented, prototype oriented, tabular, functional and message oriented programming models. Coroutines, multithreading, compile-time metaprogramming, reflection. Virtual file system. Small standard library. Mostly strict and clean style, functional code slightly messy. | Fast | Win,Linux, OSX | Dual: Either FPLL (similar to LGPL/MIT), or GPL |
| ChaiScript | Designed for C++ integration. Very easy to integrate into application - ca. three lines! Dynamically type scripting language inspired by Ruby and Scala. Type-safe inside C++. | Medium rare | Very high. | Easy | High: lambda, everything-is-an-object, closures; OO, functional, procedural and message paradigms.Very appealing syntax. Library is an exposure of C++ methods and STL types. | ??? | Source for Win, Linux, OSX. | Liberal and permissive home-cooked licence. |

Dream language: Ruby, if it would be fast enough interpreted and embedded

Seems to me that there would be little point implementing some of these scripting languages, since they aren't really a lot simpler than C++.
If the idea is to facilitate third party editing, then something that is approachable for those with little programming experience would be preferable.
If however, it's merely to avoid recompiling then some of the options above start to make more sense, although you'd be adding runtime overhead and code complexity. Rob
