Where can I find more info. about mruby?
It hit me out of the blue…
GitHub:
GitHub - mruby/mruby: Lightweight Ruby
YouTube Keynote:
Matz "mruby - Minimalistic Ruby and Its Possibility" 1 - YouTube
More info please!

I guess I missed that in Nov. 2011… So seeing it up on GitHub today
whetted my interest.

Speaking of mruby… Does MacRuby run on iOS?

Not yet but that’s pretty high priority.

Hmm, pretty impressive startup time:
$ cat testing.rb
5.times do
puts “hello world”
end
$ time bin/mruby testing.rb
hello world
hello world
hello world
hello world
hello world
real 0m0.004s
user 0m0.001s
sys 0m0.002s
And it compiles to some sort of ASCII byte-code:
$ bin/mrbc testing.rb
$ cat testing.mrb

Hi,

Yes.
matz.
I understand that it is at a very early stage and many things will have
to be fixed or added before mRuby is considered “public release” ready,
i.e. work in production code.
My question however is for mRuby “end goal”.
Would it be correct to assume and say that mRuby is very similar to Lua?
That it could also be used and embedded in C++ game engines like Lua?
As a complement to the existing basic *nix Makefiles, a new CMake-based
multi-platform build system has recently landed:
Add CMake build infrastructure by jonforums · Pull Request #182 · mruby/mruby · GitHub
Prerequisites: CMake 2.8.8, Bison, and a build toolchain.
CMake has been tested on the following systems
Home · mruby/mruby Wiki · GitHub
and may even work on other systems supported by the CMake generators.
Yes, you read that correctly…cross compiles, Arch 3.3.6, Ubuntu 12.04,
OS X Lion and Snow Leopard, and Windows using WinSDK/nmake, Visual
Studio 10, WinSDK/msbuild, and mingw/mingw-w64.
But the CMake generated Xcode project files don’t yet build OS X or iOS
targets. It’s being looked into and could use some extra help.
Blame it on the guy who wrote the CMakeLists.txt’s who doesn’t have a
Mac

Until mruby’s Home · mruby/mruby Wiki · GitHub wiki
page gets some more content, here’s a couple intro posts on using CMake.
