text_hyphen_rails

This is a Rails/ActiveRecord-wrapper for the text-hyphen package.

Installation

In your Gemfile:

gem 'text_hyphen_rails'

Then bundle install.

Usage

Say you have a model Post with a text-attribute #content

class Post < ActiveRecord::Base
  text_hyphen :content
end

text_hyphen :content adds a content_hyph-method to your model that returns the hyphenated value of content (e.g. @post.content_hyph).

There is also an html_hyphen-method which does the same but doesn't hyphenate HTML tags.

Settings

You can specify a number of settings globally or per method(s).

  # in an initializer
  TextHyphenRails.configure do |cnf|
    cnf.lang :de1
  end

  # per method
  text_hyphen :content, lang: :en_uk, hyphen: '­'
  html_hyphen :another_att, lang: :de1

The follwing options are available:

name	default	description
hyphen	"\u00ad"	the hyphen
lang	:en_uk	the identifier of the language, one of: :ca :cs :da :de1 :de2 :en_uk :en_us :es :et :eu :fi :fr :ga :hr :hsb :hu1 :hu2 :ia :id :is :it :la :mn :nl :no1 :no2 :pl :pt :ru :sv
lang_att	nil	name of an attribute (method or column) that returns a language-identifier
min_word_length	4	minimal length of word to by hyphenated
left / right	1 / 1	I'm not sure
prefix / suffix	nil / :hyph	prefix / suffix for the created methods (have no effect when replace_meth is true)
replace_meth	false	replace the original method (or attribute-getter?) with the hyphenating one and create an additional one with _orig suffix

lang_att

Make the language setting be derived from an attribute in your model.

  text_hyphen :content, lang_att: :lang

If you had existing data where the language is named more conventionally in the lang-column:

  text_hyphen :content, lang_att: :lang_for_th

  def lang_for_th
    { 'en_GB' => :en_uk,
      'en_US' => :en_us,
      ...
    }[lang]
  end

replace_meth

  html_hyphen :text, replace_meth: true

Creates a hyphenating text-method and a text_orig-method to access the unmodified value. You should use the _orig-variant in forms because otherwise the hyphenated text would be saved in the db after editing.

Exceptions

Since the underlying hyphenation algorithm does not yield absolutely perfect results, there is the possibility of defining exceptions - not yet implemented.
