Status: stable

PmWiki version 2.2.110 and newer have the variable $MarkupMarkupLevel which has exactly the same value as this recipe ($SignalMarkupMarkup).

To use the core feature with old recipes relying on the old variable, try adding this to config.php: 

$MarkupMarkupLevel = 0; 
$SignalMarkupMarkup = &$MarkupMarkupLevel;

Please report if it works. --Petko

Questions answered by this recipe

How can I tell whether my markup function is called within (:markup:) source code?

Description

The script sets a global variable, $SignalMarkupMarkup, that tells you whether and how deep the 'markup chain' (MarkupToHTML / MarkupTable execution) is inside a (:markup:) code sequence.

Some cookbooks like SlimTableOfContents, TitleMarkup, SectionEdit need to know or should at least care about that.
They should / should not / should differently execute their code inside (:markup:) page source text.

Activation

Download signalwhenmarkup.phpΔ into your cookbook folder an activate it as usual by adding the following line to your local/config.php: 

  include_once("$FarmD/cookbook/signalwhenmarkup.php");

signalwhenmarkup_php55.patch.txtΔ Patch for PHP 5.5 compatibility, contributed by Jean-Pierre Chrétien.

Usage

Whenever you need to know whether your own markup is evaluated within (:markup:) code, check the value of global $SignalMarkupMarkup: 

  $SignalMarkupMarkup == 0  - we are NOT in a (:markup:) sequence
  $SignalMarkupMarkup == 1...n we are in the n'th level

Notes

Works by redirecting the markups 'markup' and 'markupend'.
