Public Class Methods

@api private

Formats seconds into a human-readable string.

@param duration [Float, Fixnum] in seconds @return [String] human-readable time

@example

format_duration(1) #=>  "1 minute 1 second"
format_duration(135.14) #=> "2 minutes 15.14 seconds"
# File rspec-core/lib/rspec/core/formatters/helpers.rb, line 24
def self.format_duration(duration)
  precision = case
              when duration < 1 then    SUB_SECOND_PRECISION
              when duration < 120 then  DEFAULT_PRECISION
              when duration < 300 then  1
              else                  0
              end

  if duration > 60
    minutes = (duration.round / 60).to_i
    seconds = (duration - minutes * 60)

    "#{pluralize(minutes, 'minute')} #{pluralize(format_seconds(seconds, precision), 'second')}"
  else
    pluralize(format_seconds(duration, precision), 'second')
  end
end

@api private

Formats seconds to have 5 digits of precision with trailing zeros removed if the number is less than 1 or with 2 digits of precision if the number is greater than zero.

@param float [Float] @return [String] formatted float

@example

format_seconds(0.000006) #=> "0.00001"
format_seconds(0.020000) #=> "0.02"
format_seconds(1.00000000001) #=> "1"

The precision used is set in {Helpers::SUB_SECOND_PRECISION} and {Helpers::DEFAULT_PRECISION}.

@see strip_trailing_zeroes

# File rspec-core/lib/rspec/core/formatters/helpers.rb, line 60
def self.format_seconds(float, precision=nil)
  return '0' if float < 0
  precision ||= (float < 1) ? SUB_SECOND_PRECISION : DEFAULT_PRECISION
  formatted = "%.#{precision}f" % float
  strip_trailing_zeroes(formatted)
end

@api private Given a list of example ids, organizes them into a compact, ordered list.

# File rspec-core/lib/rspec/core/formatters/helpers.rb, line 102
def self.organize_ids(ids)
  grouped = ids.inject(Hash.new { |h, k| h[k] = [] }) do |hash, id|
    file, id = Example.parse_id(id)
    hash[file] << id
    hash
  end

  grouped.sort_by(&:first).map do |file, grouped_ids|
    grouped_ids = grouped_ids.sort_by { |id| id.split(':').map(&:to_i) }
    id = Metadata.id_from(:rerun_file_path => file, :scoped_id => grouped_ids.join(','))
    ShellEscape.conditionally_quote(id)
  end
end

@api private

Pluralize a word based on a count.

@param count [Fixnum] number of objects @param string [String] word to be pluralized @return [String] pluralized word

# File rspec-core/lib/rspec/core/formatters/helpers.rb, line 88
def self.pluralize(count, string)
  pluralized_string = if count.to_f == 1
                        string
                      elsif string.end_with?('s') # e.g. "process"
                        "#{string}es" # e.g. "processes"
                      else
                        "#{string}s"
                      end

  "#{count} #{pluralized_string}"
end
