# File lib/gem_bootstrap/misc_utils.rb, line 27 def files(args = {}) opts = { base_dir: Dir.pwd, recursive: false, exts: [], non_exts: [] }.merge(args) base_dir = opts[:base_dir] fail Errors::CustomError, "The directory #{base_dir} is not valid or or not readable!" unless File.exist?(base_dir) wildcard = opts[:recursive] ? '**' : '' exts = opts[:exts] non_exts = opts[:non_exts] file_with_extension = Dir.glob(File.join(base_dir, wildcard, "*.{#{exts.join(',')}}")) file_with_no_extension = no_extension_files(base_dir, wildcard, non_exts) (file_with_extension + file_with_no_extension).sort end
List files that do not have any extension
@param [String] base_dir the starting directory @param [String] wildcard the wildcard string e.g. '**' or '' (empty string) @param [Array<String>] non_exts list of file without extension @return [Array<String> list of matching files that do not have any extension
# File lib/gem_bootstrap/misc_utils.rb, line 54 def no_extension_files(base_dir, wildcard, non_exts = []) list = [] unless non_exts.empty? list = Dir.glob(File.join(base_dir, wildcard, "{#{non_exts.join(',')}}")) end list end
