Questions answered by this recipe

Can I display selected debugging messages from $MessagesFmt from only one, or from selected, message sources?
Can I make the messages from each message source hidden until shown on user demand?

Description

A drop in replacement for the PmWiki (:messages keys= :) directive. Based on code from PITS:01368.

The global variable $MessagesFmt is written to by PmWiki recipes with debug and similar information. By convention the array has two dimensions, the first a string identifying the source of the message, and the optional second dimension, a string with the debug message itself.

Differences are:

  • comma or space separated name parameters, with wildcards, can be supplied to select the groups of messages displayed
  • only messages for specified name parameters are displayed
  • name parameters are case insensitive
  • directive does not have to start at the beginning of a line
  • the output is placed within a HTML section of class=messages
  • groups of messages are separated by a blank line
  • groups of messages can be rolled up by using the details=show | hide parameter

Installation

  • download messagesreplacement-2024-05-31.phpΔ
  • copy to the /cookbook/ directory as messagesreplacement.php
  • add to config.php the line
    include_once ($FarmD/cookbook/messagesreplacement.php);

Usage

Place the directive, as described below, in your PmWiki page.

The recipe provides a page variable {$MessagesReplacementVersion} which contains the current version, and page variable $@MessagesReplacement for a (:if enabled MessagesReplacement:) recipe installation check.

Configuration

(:messages optional,list of names with,wildcards* keys="names,with,*wildcards" details=hide :)

Parameters are optional and case-insensitive:

  • names can include wild cards
  • keys= a comma separated list of names
  • details='show' or details = 'hide' provides a clickable name for each group of messages with initial value of show or hide

config.php settings

You can change the following in config.php. For example

$MessagesReplacementDebug = true; # results may vary
default: false
$MessagesReplacementHeading = true; # shows heading level 3 for each group of messages
default: false
$MessagesReplacementDetails = 'hide'; # rolls up each group of messages
default: empty (no details rollup available), values are 'hide' and 'show'
