Ruby Language Loading Source Files Loading optional files


Example

When files are not available, the require family will throw a LoadError. This is an example which illustrates loading optional modules only if they exist.

module TidBits

@@unavailableModules = []

[
      { name: 'CoreExtend', file: 'core_extend/lib/core_extend'  } \
    , { name: 'Fs'        , file: 'fs/lib/fs'                    } \
    , { name: 'Options'   , file: 'options/lib/options'          } \
    , { name: 'Susu'      , file: 'susu/lib/susu'                } \

].each do |lib|

    begin

        require_relative lib[ :file ]

    rescue LoadError

        @@unavailableModules.push lib

    end

end

end # module TidBits
