[CMake] improve the CMake language?

[Sanchez, Juan]

It is my understanding that a lot of the cmake modules are implemented in the cmake language?  It would be a big task to maintain multiple languages for the cmake modules.

While speed of a scripting language is interesting, I would expect 90% of the work would be done in the C++ part of cmake.  I would think BSD type licensing and compactness would be more important.

Interesting.  You didn't by any chance used swig to wrap it?

I admit I would be curious to see that fork of cmake to study the changes.

Using swig right now would be the best approach, as with just a few swig 
rules (if any) it would allow any user to choose whatever language he 
feels like using.

Currently, swig supports all languages mentioned in this thread so far 
and it works pretty well for projects like cmake where its .h files keep 
changing.

Eventually one scripting language could end up becoming massively more 
popular and be adopted as a "standard" for cmake.  But I'm betting in 
the future that won't matter, as several vendors are developing tools or 
frameworks to offer data interchange across the major scripting languages.

For those that don't know Lua, Lua has a very similar syntax to non-OO 
ruby albeit parenthesis are required.  It is also very fast, small and, 
just like TCL, thread safe and built for embedding (python and ruby 
still struggle with threads).  LuaJIT is probably one of the fastest JIT 
compilers for a dynamic language under any platform.
Lua's uglyness is its OO support and syntax, which is closer to OO 
Javascript or Perl's.

P.S. Disclosure: I am swig's ruby maintainer.
