Just a guy tryna learn mruby

mruby Examples

I made some examples as I was trying out mruby. Each one has a make task, then you can run the little program.

Setup

$ make setup

It should:

• update the mruby submodule
• cd mruby and make to build mruby

Hello World

Run Ruby code from a string inside a C application.

$ make hello_world
$ build/hello_world

Hello Bytecode

Compile Ruby code to mruby (RiteVM) bytecode, then run it with mruby.

$ make hello_bytecode
$ mruby/bin/mruby -b build/hello_bytecode.mrb

Hello C Code

Compile Ruby to bytecode, then execute that bytecode inside a C application.

$ make hello_c_code
$ build/hello_c_code

Hello Classes

Build a Ruby class in C, then use that Ruby class in your Ruby code.

$ make hello_classes
$ build/hello_classes

Hello Embedded

Pretend you were accessing some hardware-ish thing by C API.

fake_led.c is my pretend LEDs. Wrap it in a Ruby class, then use that in Ruby code. The Ruby code is executed inside the C application.

$ make hello_embedded
$ build/hello_embedded
