LaunchyOpenSearch is a Ruby library and commandline tool that allows to parse OpenSearch XML files and include them as search engines in the Weby plugin of the keystroke app launcher Launchy by editing Launchy's ini config file.


  • Usable as library and commandline tool

  • Tested and fully working on:

    • Ubuntu Linux 8.10 i386_64 (Ruby 1.8.7 and 1.9.1p0)

    • Debian GNU/Linux 4.0 i386 (Ruby 1.8.6)

    • Windows XP i386 (Ruby 1.8.6)

  • The commandline tool doesn't work with Ruby 1.9.x because the user-choices gem is not yet updated. A patch is available here: rubyforge.org/tracker/index.php?func=detail&aid=24307&group_id=4192&atid=16176



Launchy should be closed while using OpenSearchLaunchy

launchy-opensearch youtube.xml


Notice that the library is written with an underscore instead of the dash used in the gem's and commandline tool's name

require 'launchy_opensearch'

Determine launchy ini path

config_path = Aef::LaunchyOpenSearch.launchy_config_path

Parse an OpenSearch engine into a variable

new_engine = Aef::LaunchyOpenSearch.parse_opensearch_file('youtube.xml')

Read the launchy ini file into a variable

config = Aef::LaunchyOpenSearch.read_config_hash(config_path)

Extract hash with current search engines

current_engines = Aef::LaunchyOpenSearch.extract_config_hash(config)

Add new engine to the engines hash

new_engines = current_engines + new_engine

Patch the engines hash into the config hash

Aef::LaunchyOpenSearch.patch_config_hash(config, new_engines)

Write the config hash as ini back to the disk

Aef::LaunchyOpenSearch.write_config_hash(config, config_path)

  • hpricot

  • facets

Additional for commandline

  • user-choices

Additional for automated testing

  • rspec



gem install launchy-opensearch

Additionally for the commandline tool:

gem install user-choices

High security (recommended)

There is a high security installation option available through rubygems. It is highly recommended over the normal installation, although it may be a bit less comfortable. To use the installation method, you will need my public key, which I use for cryptographic signatures on all my gems. You can find the public key and more detailed verification information in the aef-certificates section of my rubyforge project

Add the key to your rubygems' trusted certificates by the following command:

gem cert --add aef.pem

Now you can install the gem while automatically verifying it's signature by the following command:

gem install launchy-opensearch --ignore-dependencies -P HighSecurity

Please notice that you will need other keys for dependent libraries, so you may have to install dependencies manually.

Automated testing

You can test this package through rspec on your system. First find the path where the gem was installed to:

gem which launchy-opensearch

Go into the root directory of the installed gem and run the following command to start the test runner:

rake spec

On Windows systems you have to run the following instead:

spec spec/**/*_spec.rb

If something goes wrong you should be noticed through failing examples.


This software is developed in the source code management system git hosted at github.com. You can download the most recent sourcecode through the following command:

git clone git://github.com/aef/launchy-opensearch.git

Help on making this software better is always very appreciated. If you want your changes to be included in the official release, please send me a patch through the project's tracker at rubyforge.org. You can generate a patch-file by the following command:

git diff > patch.diff

Please make sure to write tests for your changes and notice that I can't promise to include your changes before reviewing them.
