Rb++ / rbgccxml 0.1.1 bugfix release

== CHANGELOG

=== 0.1.1

  • rb++: Added rice as a gem dependency
  • rb++: explicitly requiring fileutils now
  • all: Added ldflags / cxxflags options for passing in other custom
    command line arguments
  • gccxml: Error message about how to fix the file execution flags is
    now consistent across platforms.

== What is rb++ / rbgccxml?

For anyone who wants an alternative to SWIG for generating Ruby
extensions from C++ header files, look no further.

== Project

Documentation: http://rbplusplus.rubyforge.org

Project Page: http://rubyforge.org/projects/rbplusplus

== Installation

This single command will grab the whole stack needed for rb++ to work.

gem install rbplusplus

The stack includes three libraries: rb++, rbgccxml, and gccxml_gem and
also installs rice

== rb++

Rb++ makes it almost trivially easy to create Ruby extensions for any
C or C++ library / code. In the simplest of cases, there is no need to
ever touch C, everything is done in a very simple and clean Ruby API.

As this is an 0.1 release, not all of C++ is supported. The current
constructs that rb++ can wrap are:

  • functions
  • classes
  • class methods
  • static class methods

Rb++ allows one to define Ruby Modules and put wrapped code in them as
well.

== rbgccxml

RbGCCXML allows one to easily parse out and query C++ code. This
library uses GCC-XML to parse out the C++ code into XML, and then
Hpricot to parse and query that XML.

== gccxml_gem

GCC-XML (www.gccxml.org) is an application that takes takes the parse
tree of G++ and constructs a very parsable and queryable XML file with
all related information.

The third part of the stack is this gem that includes a binary build
of GCC-XML for your platform, to make it trivially easy to install.
Platforms currently supported are:

  • Linux 32 & 64 bit
  • Mac OS X 10.5 (may have an issue with 10.4 or lower, need to test
    these)
  • Windows 32-bit via Cygwin

== Requirements

== Code

All code is hosted at github

rb++: http://github.com/jameskilton/rbplusplus/tree/master
rbgccxml: http://github.com/jameskilton/rbgccxml/tree/master
gccxml_gem: http://github.com/jameskilton/gccxml_gem/tree/master

== Notes

Released under the MIT licence.

For those familiar with py++ / pygccxml, the similarities are in
function only. Rb++ / rbgccxml were written from scratch to take
advantage of the Ruby language to it’s fullest.

Bugs, patches, feature requests, et al should be posted to the
project’s tracker.

Discussion can be here or the project’s rubyforge forums.

Dear Jason,

thanks for your work ! This is really, really nice.
I have a suggestion for the documentation.
Would it possible to include some explicit easy examples in the
documentation, to demonstrate how to extend Ruby with a function,
a class , a module written in C++, somewhat like what Mark V.
has done for the tradition C/Ruby extension here :

http://www.ociweb.com/mark/programming/Ruby_C_Extensions.pdf ?

This might save people some time from digging into the test directory
and demonstrate how much easier life becomes through your gem.

Thank you very much agaian for your nice work !

Best regards,

Axel

like eg., the ones

Psssst! Schon vom neuen GMX MultiMessenger gehört?
Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger

Most definitely. Documentation will be as constantly changing as the
code-base itself. I threw together a quick sample for both rb++ and
rbgccxml, though you’re rigth, it will work better right in the
documentation. I’ll get some pages up with detailed samples and
examples.
