Questions answered by this recipe

• How can I count the number of lines between two markers on a page?
• How can I count lines between markers on another page?
• How can I avoid marker duplication when using anchors?

Description

This recipe provides a markup directive to count the number of text lines between two markers on a wiki page. It is useful for documentation statistics, validation of structured sections, or technical overviews where only parts of a page should be evaluated.

Markers are passed in a protected form to avoid duplication when PmWiki renders anchors.

Installation

1. Download countbetweenmarkers.zipΔ
2. Copy countbetweenmarkers.php into your cookbook/ directory
3. Add the following line to config.php: include_once("$FarmD/cookbook/countbetweenmarkers.php");

Usage

Basic usage on the current page:

  (:pmlinecount start="[[#Pm_Start]]" end="[[#Pm_End]]":)

Count lines on another page:

  (:pmlinecount page=Group.Page start="[[#Pm_Start]]" end="[[#Pm_End]]":)

The result is the number of text lines found between the two markers.

Notes

• The prefix Pm_ must be used in marker names to prevent anchor duplication.
• Marker names are arbitrary.
• Anchors in the page can be named freely, e.g. #Foo and #Bar; in the directive call use [[#Pm_Foo]] and [[#Pm_Bar]].
• In the directive call, prefix marker names with Pm_ (e.g. ) to prevent anchor duplication.
• Empty or missing markers return no output.
• Counts raw page text lines; visual line wrapping is ignored.
