I have a Buildr extension that I'm packaging as a gem. I have a collection of scripts that I want to add to a package. Currently, I have these scripts stored as a big text block that I'm writing to file. I would prefer to have individual files that I can either copy directly or read/write back out. I would like these files to be packaged into the gem. I don't have a problem packaging them in (just stick them in the file system before rake install) but I can't figure out how to access them. Is there a Gem Resources bundle type thing?
There are basically two ways,
1) You can load resources relative to a Ruby file in your gem using __FILE__:
def path_to_resources
File.join(File.dirname(File.expand_path(__FILE__)), '../path/to/resources')
end
2) You can add arbitrary paths from your Gem to the $LOAD_PATH variable and then walk the $LOAD_PATH to find resources, e.g.,
Gem::Specification.new do |spec|
spec.name = 'the-name-of-your-gem'
spec.version ='0.0.1'
# this is important - it specifies which files to include in the gem.
spec.files = Dir.glob("lib/**/*") + %w{History.txt Manifest.txt} +
Dir.glob("path/to/resources/**/*")
# If you have resources in other directories than 'lib'
spec.require_paths << 'path/to/resources'
# optional, but useful to your users
spec.summary = "A more longwinded description of your gem"
spec.author = 'Your Name'
spec.email = '[email protected]'
spec.homepage = 'http://www.yourpage.com'
# you did document with RDoc, right?
spec.has_rdoc = true
# if you have any dependencies on other gems, list them thusly
spec.add_dependency('hpricot')
spec.add_dependency('log4r', '>= 1.0.5')
end
and then,
$LOAD_PATH.each { |dir| ... look for resources relative to dir ... }
