rubyuno is a Ruby-UNO (Universal Network Object; ['ju:nou]) bridge. UNO is used to construct OpenOffice.org so that you can play with the office. Rubyuno is implemented as Ruby extension library written in C++, but the bridge is not so fast because value conversion and multiple API call consume time. Rubyuno is not well suited for task like template creation; generating ODF (Open Document Format) files is a better option.
rubyuno is a fork of RUNO, converted into a gem so that the extensions do not need to be compiled manually. However, it has not been tested on a wide variety of platforms. If you encounter compilation difficulties and are able to resolve them, please create a pull request so that we can get this working on as many platforms as possible!
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install rubyuno
In order for rubyuno to compile, the following must already be installed on the system:
OpenOffice.org and OpenOffice.org SDK (tested with version 3.4).
The SDK will need to be set up after installation. In order to do this,
configure.plwithin the SDK's installation directory (eg. /opt/openoffice.org/basis3.4/sdk) needs to be run. This will create an SDK directory within the current user's home directory (the script has an option to change the installation directory but seems to not work) with some shell scripts.
The shell scripts will be named something like
envis your server environment and
extis a shell type (ie.
setsdkenv_unix.sh). Please read the SDK documentation for more information.
Ruby 1.9 and its headers (you may need to compile Ruby with the
In addition to the SDK's environment variable set up script (as mentioned above), rubyuno needs two environment variables to function correctly.

Specifies fundamental(rc|.ini) file with vnd.sun.star.pathname protocol.
You may wish to update your
/etc/profile or the like with the following to automatically set these up:
. ~/openoffice.org3.4_sdk/$(hostname)/setsdkenv_unix.sh >/dev/null export URE_BOOTSTRAP="vnd.sun.star.pathname:$OFFICE_PROGRAM_PATH/fundamentalrc"
OpenOffice must be running as a service first in order to interact with it (rubyuno uses port 2083 by default):
soffice -headless -nologo -nofirststartwizard - accept="socket,host=localhost,port=2083;urp;StarOffice.ServiceManager"
Once it is running, you can connect to it from ruby:
require 'rubyuno' ctx = Uno::Connector.bootstrap smgr = ctx.getServiceManager desktop = smgr.createInstanceWithContext("com.sun.star.frame.Desktop", ctx) doc = desktop.loadComponentFromURL("private:factory/swriter", "_blank", 0, ) doc.getText.setString("Hello from Ruby!")
