\ No newline at end of file +--[[JoshTriplett]] + +I'm not comfortable with exposing regexps to web editing. At the very least +it's trivial to construct regexps that take indefinitely long to match +certain strings, which could be used to DOS ikiwiki. At worst, perl code +can be embedded in regexps in a variety of ways that are painful to filter +out, and perl's regexp engine could also potentially have bugs that could +be exploited by user-supplied regexps. + +It seems that a better place to put this kind of text munging is in +special-purpose plugins. It should be very simple to write plugins for the +above two examples, that look identical to the user as what you described. + +--[[Joey]] |
