Tagz and entities

Ruby

Is this how tagz.<< is supposed to work? It seems that << and #concat
behave differently w.r.t. entity quoting.

require ‘tagz’
include Tagz.globally

arrow = “↑”
html = html_ {

tagz << arrow

tagz.concat arrow

___ arrow
}

puts html

END

Output:

&uarr; ↑

↑

correct. escape in the normal case (<<) but concat works directly
without quoting.

cheers.

Thanks. That seems a bit arbitrary since these methods are the same for
strings. It’s something you just have to remember, but then forget when
you come back to the code after a while.

Would it be possible for the object returned by #tagz to have a method,
say #literally or #unescaped, which returns an object which delegates
back to the original. On the original Tagz::Document, #<< and #concat
have the same quoting behavior. On the delegator, they do not quote.

Just a thought…

yeah i can see that. i was thinking more of erb’s concat - which
appends literal objects.

that is kinds of how it works already.

   def << string
     case string
       when Document
         super string.to_s
       else
         super XChar.escape(string.to_s)
     end
     self
   end

and anything returned by tagz is a document. you can even do

tagz << tagz(‘ not escaped ’)

maybe i’ll just reserver #write of unescaped writing - there needs to
be one shortcut i think.
