If I take the value from a tiddler field like {{!!add.filter}} then it
works fine but I need to check and clean this value before it goes to the
filter. Otherwise [search:text:regexp{!!add.filter}] crashes my wiki if it
contains "||" somewhere or "|" at the edge. There shoud be more checks but
I start with this one.
So i've made JS macro and checked its results - ok. It replaces || to | and
removes | prefix an suffix
...
exports.run = function(regexp) {
regexp= regexp.replace(/([\|\\\{\}]){2,}/g, "$1");
regexp= regexp.replace(/^([\|]){1,}/g, "");
regexp= regexp.replace(/([\|]){1,}$/g, "");
return regexp;
};
But when I
\define validFilter()<$macrocall $name="validateregexp"
regexp={{!!add.filter}}/>
and change filter
[search:text:regexp{!!add.filter}]
to
[search:text:regexp<validFilter>]
then the second filter always returns nothing even if {!!add.filter}
and <validFilter> are equal and the first filter works correctly.
I would like to understand why. And how I should apply my macro to the
filter.
