Allowing users to add (:directives:) may be risky, they could add
(:noaction:), (:noleft:), (:noheader:), (:notitle:), (:redirect SomeWhere:),
(:linebreaks:) and other possibly dangerous / defacing markups like (:if
If you really want to allow directives with "(:" and ":)" in posts of PmForm,
you can define another "PTV Pattern", and remove the existing one:
unset($PmFormPostPatterns); # or each one individually
'/(\\(== *(\\w[-\\w]*) *:(?!\\))\\s?)(.*?)(==\\))/s';
Thus, your multiline PageTextVariables will be stored in fields like this:
Note that this is a big change in how people use PageTextVariables in their
pages, so if someone is already using them, they may not want to change all
in order to use your recipe.
If it is possible to not store page (:directives:) via PmForm, or agree to the
default behavior that adds a space, your life and the life of the users of
your recipe will be much easier.
Also, a wiki writer having that much knowledge of PmWiki (to manipulate page
directives), he could just use the "edit" link to modify the page, couldn't
P.S. If you just need to add content in a page, but not edit it later in
PmForms, you could possibly add some (:directive:) in your local templates.
See how the user input is handled at PmForm:Comments and PmfTemplates:
