require_paths() click to toggle source

Paths in the gem to add to $LOAD_PATH when this gem is activated.

See also require_paths=

If you have an extension you do not need to add "ext" to the require path, the extension build process will copy the extension files into “lib” for you.

The default value is "lib"

Usage:

# If all library files are in the root directory...
spec.require_path = '.'
 
               # File rubygems/basic_specification.rb, line 238
def require_paths
  return raw_require_paths unless have_extensions?

  [extension_dir].concat raw_require_paths
end
            
source_paths() click to toggle source

Returns the paths to the source files for use with analysis and documentation tools. These paths are relative to full_gem_path.

 
               # File rubygems/basic_specification.rb, line 248
def source_paths
  paths = raw_require_paths.dup

  if have_extensions? then
    ext_dirs = extensions.map do |extension|
      extension.split(File::SEPARATOR, 2).first
    end.uniq

    paths.concat ext_dirs
  end

  paths.uniq
end
            
stubbed?() click to toggle source

Whether this specification is stubbed - i.e. we have information about the gem from a stub line, without having to evaluate the entire gemspec file.

 
               # File rubygems/basic_specification.rb, line 304
def stubbed?
  raise NotImplementedError
end

def this; self; end
            
to_fullpath(path) click to toggle source

Full path of the target library file. If the file is not in this gem, return nil.

 
               # File rubygems/basic_specification.rb, line 162
def to_fullpath path
  if activated? then
    @paths_map ||= {}
    @paths_map[path] ||=

          File.file?(fullpath = "#{dir}/#{path}#{suf}")
