This command was used:
find . -type f -print0 | xargs -0 sed -i 's/return undef/return/g'
The idea behind this commit is described on http://oddmuse.org/wiki/Refactoring page.
In short: 'return undef' returns (undef) in list context (a list with one element),
which is wrong.
Replaced the $Id$ tags in $WikiDescription for all the modules and wiki.pl itself with a link to the source and an appropriate wiki page, if possible. This is shown in action=version and should help users figure out what another wiki has installed.
the InElement() and [Add|Close]HtmlEnvironment() family of
functions to add, remove, and search against HTML tag attributes
for all recently stacked HTML tag environments. Previously, tag
attributes were not retained; they were simply returned as text
from the AddHtmlEnvironment() function. Markup modules producing
complex HTML -- particularly, complex HTML having deeply nested
span or div tags -- can leverage the newly rewritten functions,
below, to simplify, streamline, and "clean up" their markup code.
(InElement): Rewritten to use this new variable.
(AddHtmlEnvironment): Rewritten to use this new variable.
(CloseHtmlEnvironment): Rewritten to use this new variable.
(CloseHtmlEnvironments): Rewritten to use this new variable.
(CloseHtmlEnvironmentUntil): Rewritten to use this new variable.
(AddOrCloseHtmlEnvironment): New function. Added so as to avoid
duplicate redefinition in the Creole, Creole Addition, and Usemod
modules.
* modules/usemod.pl (UsemodRule): Corrected erroneous usage of the
InElement() function. (I don't think UsemodRule() was ever quite
right, really; it's a bit surprising it worked this long!)
(RFC, ISBN, WikiHeading): Moved to modules/usemod.pl.
(PrintSearchResult): No longer strip common HTML tags (since those
are now defined in modules/usemod.pl).
(ApplyRules): Moved many rules to modules/usemod.pl.
(InitLinkPatterns): No longer set $RFCPattern and $ISBNPattern.
(InitVariables): No longer set @HtmlTags
($RFCPattern, $ISBNPattern, @HtmlTags, $HtmlTags, $HtmlLinks)
($RawHtml): Moved to modules/usemod.pl.
