1 [![Build Status][build-status-img]][travis-ci]
5 mruby is the lightweight implementation of the Ruby language complying to (part
6 of) the [ISO standard][ISO-standard]. Its syntax is Ruby 1.9 compatible.
8 mruby can be linked and embedded within your application. We provide the
9 interpreter program "mruby" and the interactive mruby shell "mirb" as examples.
10 You can also compile Ruby programs into compiled byte code using the mruby
11 compiler "mrbc". All those tools reside in the "bin" directory. "mrbc" is
12 also able to generate compiled byte code in a C source file, see the "mrbtest"
13 program under the "test" directory for an example.
15 This achievement was sponsored by the Regional Innovation Creation R&D Programs
16 of the Ministry of Economy, Trade and Industry of Japan.
20 The stable version 2.0.1 of mruby can be downloaded via the following URL: [https://github.com/mruby/mruby/archive/2.0.1.zip](https://github.com/mruby/mruby/archive/2.0.1.zip)
22 The latest development version of mruby can be downloaded via the following URL: [https://github.com/mruby/mruby/zipball/master](https://github.com/mruby/mruby/zipball/master)
24 The trunk of the mruby source tree can be checked out with the
27 $ git clone https://github.com/mruby/mruby.git
29 You can also install and compile mruby using [ruby-install](https://github.com/postmodern/ruby-install), [ruby-build](https://github.com/rbenv/ruby-build) or [rvm](https://github.com/rvm/rvm).
33 The URL of the mruby home-page is: [http://www.mruby.org](http://www.mruby.org).
37 We don't have a mailing list, but you can use [GitHub issues](https://github.com/mruby/mruby).
39 ## How to compile and install (mruby and gems)
41 See the [doc/guides/compile.md](doc/guides/compile.md) file.
45 To run the tests, execute the following from the project's root directory.
51 $ ruby ./minirake test
53 ## How to customize mruby (mrbgems)
55 mruby contains a package manager called *mrbgems*. To create extensions
56 in C and/or Ruby you should create a *GEM*. For a documentation of how to
57 use mrbgems consult the file [doc/guides/mrbgems.md](doc/guides/mrbgems.md). For example code of
58 how to use mrbgems look into the folder *examples/mrbgems/*.
62 mruby is released under the [MIT License](LICENSE).
66 mruby has chosen a MIT License due to its permissive license allowing
67 developers to target various environments such as embedded systems.
68 However, the license requires the display of the copyright notice and license
69 information in manuals for instance. Doing so for big projects can be
70 complicated or troublesome. This is why mruby has decided to display "mruby
71 developers" as the copyright name to make it simple conventionally.
72 In the future, mruby might ask you to distribute your new code
73 (that you will commit,) under the MIT License as a member of
74 "mruby developers" but contributors will keep their copyright.
75 (We did not intend for contributors to transfer or waive their copyrights,
76 Actual copyright holder name (contributors) will be listed in the AUTHORS
79 Please ask us if you want to distribute your code under another license.
83 See the [contribution guidelines][contribution-guidelines], and then send a pull
84 request to <http://github.com/mruby/mruby>. We consider you have granted
85 non-exclusive right to your contributed code under MIT license. If you want to
86 be named as one of mruby developers, please include an update to the AUTHORS
87 file in your pull request.
