Persistent tag attributes [SOLVED]

stefanofdenmark

This is my first attempt at a plugin, so please be gentle ;-)
I started off with the color plugin https://www.dokuwiki.org/devel:syntax_plugins#sample_plugin_2_-_color, at that makes sense to me.
Now I want to make some decisions based on the attributes of the opening tag. This is handled in DOKU_LEXER_ENTER, all well and good, but the DOKU_LEXER_EXIT needs to be aware of what happened in DOKU_LEXER_ENTER - How do I do that?

For example if the color in the mentioned plugin equals blue, I want the text to be in a <code> block instead of a <span> and hence I need to DOKU_LEXER_EXIT to put a </code> tag instead of the </span> tag based on the attribute of the opening <color> tag.

I hope that makes sense and someone can point me in the right direction.

Best regards
Stefan

You can save your color in a class property during the ENTER phase. It will still be held in memory when you reach the EXIT phase.

So:

   private $color; /* or var $color */
   
   function handle() {
        case DOKU_LEXER_ENTER : 
            $this->color = $color;
   }
    
  function render() {
           case DOKU_LEXER_EXIT :      
              if$this->color == 'blue') do the blue color thing;  
   }

Simple and elegant.
I was so focused on a DokuWiki solution that I did not see the pure PHP solution.

Thank you very much!
Onward to new features, challenges and new knowledge :-)
