Patch by Google Inc. [ruby-core:45073]. * configure.in (RUBY_NACL): New M4 func to configure variables for NaCl. (RUBY_NACL_CHECK_PEPPER_TYPES): New M4 func to check the old names of Pepper interface types. (BTESTRUBY): New variable to specify which ruby should be run on "make btest". NaCl can run the built binary by sel_ldr, but it need rbconfig.rb. So this variable is distinguished from $MINIRUBY. * thread_pthread.c: Disabled some features on NaCl. * io.c: ditto. * process.c: ditto. * signal.c: ditto. * file.c: ditto. * missing/flock.c: ditto. * nacl/pepper_main.c: An example implementation of Pepper application that embeds Ruby. * nacl/example.html: An example of web page that uses the Pepper application. * nacl/nacl-config.rb: Detects variants of NaCl SDK. * nacl/GNUmakefile.in: Makefile template for NaCl specific build process. * nacl/package.rb: script for packaging a NaCl-Ruby embedding application. * nacl/reate_nmf.rb: Wrapper script of create_nmf.py * dln.c (dln_load): Added a hack to call on NaCl. * util.c (ruby_getcwd): Path to the current directort is not available on NaCl. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@35672 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

<h1>Native Client Module Ruby</h1>

|

<!-- Load the published .nexe. This includes the 'nacl' attribute which
|
|
shows how to load multi-architecture modules. Each entry in the "nexes"
|
|
object in the .nmf manifest file is a key-value pair: the key is the
|
|
instruction set architecture ('x86-32', 'x86-64', etc.); the value is a URL
|
|
for the desired NaCl module.
|
|
To load the debug versions of your .nexes, set the 'nacl' attribute to the
|
|
_dbg.nmf version of the manifest file.
|
|
|
|
Note: Since this NaCl module does not use any real-estate in the browser,
|
|
it's width and height are set to 0.
|
|
|
|
Note: The <EMBED> element is wrapped inside a <DIV>, which has both a 'load'
|
|
and a 'message' event listener attached. This wrapping method is used
|
|
instead of attaching the event listeners directly to the <EMBED> element to
|
|
ensure that the listeners are active before the NaCl module 'load' event
|
|
fires. This also allows you to use PPB_Messaging.PostMessage() (in C) or
|
|
pp::Instance.PostMessage() (in C++) from within the initialization code in
|
|
your NaCl module.
