[pmwiki-users] Create a Wiki Trail from dynamic pages

Your a star!  worked first time.  One thing that threw me though is that you said "create a modified version of scripts/trails.php in your local/ directory."  The only way I could get it to work (read: pick up my change) was to modify the scripts/ version.  If I put a local copy in the local/ directory this looks like it's not used.
Do I have to do anything else to 'activate' a local copy of a PmWiki core script?
Thanks very much for your help,

You'll need to create a modified version of scripts/trails.php
in your local/ directory.

After that script reads the page, but before it  explodes the content
into lines, you'll need to match \\(:include\\s+(\\S.*?):\\)  and
process the result through the IncludeText($pagename, '$1')

Something like

$trailpage['text'] = preg_replace('/\\(:include\\s+(\\S.*?):\\)/ei',
    "IncludeText($pagename, '$1')",$trailpage['text']);

This is off the top of my head, so is probably not quite right.

If this 'implementation details are left as an exercise for the reader'
hint is not enough, let me know and we'll look more closely at what's needed.
