HtmlCalendar

HtmlCalendar is an extremely lightweight/extensible gem for creating HTML calendars in Rails (>= 3.1).

Want to overwrite the built-in views? No problem. Want clean markup? It'll give you clean markup. Want a full-featured Google Calendar clone? It'll give you clean markup.

1. Add gem "html_calendar" to your Gemfile
2. bundle

The html_calendar helper makes it easy to create a calendar for any date:

<!-- a calendar for the current month -->
<%= html_calendar %>

<!-- a calender for 3 months in the future -->
<%= html_calendar Date.current + 3.months %>

If you need customized date logic, you can also pass html_calendar a presenter:

<%= html_calendar Date.current, presenter: MyCustomDatePresenter %>

Your presenter class needs to inherit from HTMLCalendar::DatePresenter, and should implement the html_classes method.

class MyCustomDatePresenter < HTMLCalendar::DatePresenter
  # Available methods: `html_classes`, `date` and `template`

  def html_classes
    if monday?
      ['a-case-of-the-mundays']
    else
      super
    end
  end

  private

  def monday?
    date.wday == 1
  end
end

You can overwrite any of the view partials by creating a directory at app/views/html_calendar/calendar and adding replacement files:

• I18n support
• Better test coverage
• Basic stylesheet (opt-in)
• Ability to overwrite partial path
