This script handles various "fixup transitions" that might need to
|
|
occur to help existing sites smoothly upgrade to newer releases of
|
|
PmWiki. Rather than put the workarounds in the main code files, we
|
|
try to centralize them here so we can see what's deprecated and a
|
|
simple switch (?trans=0 in the url) can tell the admin if his site
|
|
is relying on an outdated feature or way of doing things.
|
|
|
|
Transitions defined in this script:
|
|
|
|
$Transition['nosessionencode'] - turn off session encoding
|
|
|
|
$Transition['version'] < 2001967 - all transitions listed above
|
|
|
|
$Transition['wspre'] - leading spaces are pre text
|
|
|
|
$Transition['version'] < 2001941 - all transitions listed above
|
|
|
|
$Transition['wikiwords'] - 2.1-style WikiWord processing
|
|
|
|
$Transition['version'] < 2001924 - all transitions listed above
|
|
|
|
$Transition['abslinks'] - absolute links/page vars
|
|
|
|
$Transition['version'] < 2001901 - all transitions listed above
|
|
|
|
$Transition['vspace'] - restore <p class='vspace'></p>
|
|
|
|
$Transition['version'] < 2001006 - all transitions listed above
|
|
|
|
$Transition['fplbygroup'] - restore FPLByGroup function
|
|
|
|
$Transition['version'] < 2000915 - all transitions listed above
|
|
|
|
$Transition['mainrc'] - keep using Main.AllRecentChanges
|
|
$Transition['mainapprovedurls'] - keep using Main.ApprovedUrls
|
|
$Transition['pageeditfmt'] - default $PageEditFmt value
|
|
$Transition['mainpages'] - other default pages in Main
|
|
|
|
$Transition['version'] < 1999944 - all transitions listed above
|
|
|
|
To get all of the transitions for compatibility with a previous
|
|
version of PmWiki, simply set $Transition['version'] in a local
|
|
configuration file to the version number you want compatibility
|
|
with. All of the transitions associated with that version will
|
|
then be enabled. Example:
|
|
|
|
# Keep compatibility with PmWiki version 2.0.13
|
|
$Transition['version'] = 2000013;
|
|
|
|
To explicitly enable or disable specific transitions, set
|
|
the corresponding $Transition[] element to 1 or 0. This will
|
|
override the $Transition['version'] item listed above. For
|
|
example, to enable just the 'pageeditfmt' transition, use
|
|
|
|
$Transition['pageeditfmt'] = 1;
|
