A few new functions were added:
PCCF() PmWiki Create Callback Function
PPRE() PmWiki preg_replace eval
PPRA() PmWiki preg_replace arrays
Markup_e() like Markup() but with replacement evaluated in a Callback
We'll document these functions once we're sure they work like we want
them to work. But the Markup_e() function should not change a lot in
the future, so I'll give an example:
if until now a recipe used:
Markup('id', 'direcives', '/p(a)tte(rn)/e', "ReplFunc('$1', '$2')");
now it can alternatively use:
Markup_e('id', 'direcives', '/p(a)tte(rn)/', "ReplFunc(\$m[1],
\$m[2])");
so the changes are:
Markup_e() instead of Markup()
the pattern without the "e" modifier after the last /
the replacement with $m[0], $m[1], $m[2], $m[3] instead of '$0', '$1'
etc.
(this last one is not automatic, we should be careful there)
If a recipe uses preg_replace with an e modifier directly in its code,
is there a pmwiki-recommended way to use the new pmwiki functions and/or
replace the preg_replace calls with suitable preg_replace_callback? TIA
