Features
mruby 1.0 supports the Ruby 2.1 core API but none of the standard library. As well as being able to execute most basic Ruby code, mruby also features a bytecode compiler and virtual machine, as well as the ability to be easily embedded and integrated into C or C++ code, in a similar manner to Lua or Tcl.
mruby also aims to be compliant with the ISO/IEC 30170:2012 standard.
Calling mruby from C
Assuming that you have mruby installed and in your path, the following program can be compiled and executed by running the following command from your terminal:
$ cc example.c -lmruby -lm -o example $ ./examplePrecompiled Bytecode
mruby includes a minimalistic virtual machine used to execute mruby bytecode, nicknamed ritevm:
$ mrbc test.rb $ mruby -b test.mrbThe first command compiles Ruby code to mruby bytecode, creating a file called "test.mrb", which can then be executed by appending the "-b" flag to the normal interpreter arguments.
