Module: Psychgus::Stylables::CapStylable

Includes:
Psychgus::Styler
Included in:
Psychgus::Stylers::CapStyler
Defined in:
lib/psychgus/stylables.rb

Overview

A Capitalizer for Scalars.

Examples:

require 'psychgus'

data = {
  'eggs' => [
    'omelette',
    'BBQ eggs',
    'hard-boiled eggs',
    'soft_boiled eggs',
    'fried@eggs'
]}

seq_flow = Psychgus::SeqFlowStyler.new

puts data.to_yaml(stylers: [Psychgus::CapStyler.new,seq_flow])

# Output:
# ---
# Eggs: [Omelette, BBQ Eggs, Hard-Boiled Eggs, Soft_Boiled Eggs, Fried@eggs]

puts data.to_yaml(stylers: [Psychgus::CapStyler.new(each_word: false),seq_flow])

# Output:
# ---
# Eggs: [Omelette, BBQ eggs, Hard-boiled eggs, Soft_boiled eggs, Fried@eggs]

puts data.to_yaml(stylers: [Psychgus::CapStyler.new(new_delim: '(o)'),seq_flow])

# Output:
# ---
# Eggs: [Omelette, BBQ(o)Eggs, Hard(o)Boiled(o)Eggs, Soft(o)Boiled(o)Eggs, Fried@eggs]

class Cappie
  include Psychgus::CapStylable

  def cap_word(word)
    return 'bbq' if word.casecmp('BBQ') == 0

    super(word)
  end
end

puts data.to_yaml(stylers: [Cappie.new(new_delim: '*',delim: /[\s@]/),seq_flow])

# Output:
# ---
# Eggs: [Omelette, bbq*Eggs, Hard-boiled*Eggs, Soft_boiled*Eggs, Fried*Eggs]

Instance Method Details

#cap_word(word) ⇒ String

Capitalize an individual word (not words).

This method can safely be overridden with a new implementation.

Parameters:

  • word (nil, String) —

    the word to capitalize

Returns:

  • (String) —

    the capitalized word

# File 'lib/psychgus/stylables.rb', line 85

def cap_word(word)
  return word if word.nil? || word.empty?

  # Already capitalized, good for all-capitalized words, like 'BBQ'
  return word if word[0] == word[0].upcase

  return word.capitalize
end

#initialize(each_word: true, new_delim: nil, delim: /[\s_\-]/, **kargs) ⇒ Object

Parameters:

  • each_word (true, false) (defaults to: true) —

    whether to capitalize each word separated by delim

  • new_delim (nil, String) (defaults to: nil) —

    the replacement for each delim if not nil

  • delim (String, Regexp) (defaults to: /[\s_\-]/) —

    the delimiter to split on

  • kargs (Hash) —

    capture extra keyword args, so no error for undefined args

  @delim = Regexp.new("(#{delim})")
  @each_word = each_word
  @new_delim = new_delim
end
