  • Tag changed from “latex” to “latex, notextile”
  • Milestone order changed from “0” to “0”

  The prob looks more general to me, the '==' operator does not work
  when one or more spaces follow opening initial '==' or occur immediately
  before the closing '=='.

  == This is not strong but flanked by asterix ==

  to_html produces:

  == his is not strong but flanked by asterix ==

  to_latex:

  == \textbf{his is not strong but flanked by asterix} ==

  I can't figure out what I need to override at present to correct this.
  where is the code handling the '==' ... '=='? I just see:

  def ignore(opts)
  opts:[text] end
  alias_method :notextile, :ignore

  in base.rb.

  Any pointers??

  Ok, the parsing seems to be in the C-code, so here a fix
  avoiding going near that:

  module RedCloth::Formatters::LATEX
  
    # Redefine empty before_transform in Base.rb to strip 
    # the unwanted spaces in Latex convertions.
  
    def before_transform
      text.gsub!( /==\s*(.*?)\s*==/, '==\1==' )
    end
  end
  

  Note - the same move for the html formatter did not work,
  but then that Formatter already re-implements the empty
  base class function ... not sure if that's the reason.

  ... and yet another update: text inside each == .. == needs to be escaped:

  module RedCloth::Formatters::LATEX
  
    # Redefine empty before_transform in Base.rb to strip 
    # the unwanted spaces in Latex convertions.
  
    def before_transform
      text.gsub!( /==\s*(.*?)\s*==/ ) do |m|
        m = escape "==#{$1}=="
      end
    end
  end

  I think there's a dilemma here:

  In this example we'd need to escape:
  

     == expect asterisk in my pdf ==
  

  In this example would not escape:
  

     == \textbf{my latex code} ==
  

  Nice one to sort out!
