Sorts an array of strings in the same manner as the Linux sort command running with the --dictionary-order option. Only blanks and alphanumeric characters are considered.
I created this gem because I needed to use the comm command in a Capistrano recipe, and wanted to sort the list of files in Ruby. comm requires the input files to be sorted using the collating sequence specified by `LC_COLLATE', and this defaults to dictionary sort.
Add the following line to your Gemfile:
gem 'dictionary_order_sort'You can now use the dict_sort method on arrays or sets. Array elements must be strings, or respond to to_s.
Use it like this:
["a", "a-2", "_a-3", "abc_", "_def_"].dict_sort
#=> ["a", "a-2", "_a-3", "abc_", "_def_"]
