nacl-mruby is a mruby interpreter works on Native Client (NaCl). Ruby code runs on the browser, and you can use Pepper API from Ruby.

This is ALPHA version. Some APIs still not working 😢

Access these pages from Google Chrome browser.

• repl: A read-eval-print loop console
• mandelbrot: Plotting mandelbrot set

• Native Client SDK pepper_31 or later
  • See https://developers.google.com/native-client/dev/sdk/download
• depot_tools
  • See http://dev.chromium.org/developers/how-tos/install-depot-tools
• Google Chrome 31 or later
• GNU make

First, set NACL_SDK_ROOT environment variable to the path to the Native Client SDK. For example:

$ export NACL_SDK_ROOT=/Users/notozeki/src/nacl_sdk/pepper_31

Second, check out naclports. You need to install depot_tools to use gclient.

$ mkdir naclports
$ cd naclports
$ gclient config --name=src  https://chromium.googlesource.com/external/naclports.git
$ gclient sync

# See https://code.google.com/p/naclports/wiki/HowTo_Checkout for more details.

Third, install PCRE library via naclports. PCRE is required in order to compile mruby-pcre-regexp gem later.

$ cd src
$ ./make_all.sh pcre

Clone nacl-mruby repository into a directory wherever you like. And setup submodules.

$ git clone git://github.com/notozeki/nacl-mruby.git
$ cd nacl-mruby
$ git submodule init
$ git submodule update

Then, run make.

$ cd plugin
$ make

Now you have newlib directory and nacl-mruby executables in it.

Currently there are three examples:

• examples/simple
• examples/mandelbrot
• examples/repl

To run an example, change directory to the example directory, and run make and make run.

$ cd ../examples/mandelbrot
$ make
$ make run

Now http server is running in the local, access localhost:5103 from Google Chrome browser.

(Coming soon...)
