oofcanvas: livecheck doesn't work

[ryandesign (Ryan Carsten Schmidt)]

% port livecheck oofcanvas
Error: cannot check if oofcanvas was updated (The requested URL returned error: 403)

What do I need to do to get livecheck to work? Is there any benefit if the port maintainer and the port developer are the same person? There is an update in the download directory on our server, but as I commented in #68085 it's not relevant for MacPorts.

livecheck is user-visible. It's even on our web site now. See the circled exclamation mark to the right of the version here:

​https://ports.macports.org/port/oofcanvas/details/

To fix livecheck, you set livecheck.type, livecheck.url, and livecheck.regex correctly. livecheck.type is typically regex to indicate that you want MacPorts to run a single-line regular expression over the contents of a page. If you want a multi-line regex instead, use regexm. livecheck.url is the page you want it to fetch, and livecheck.regex is the regular expression you want it to use. Put capturing parentheses around the part of the regular expression that represents a found version number. MacPorts will collect all the matches, sort them using its version comparison procedure, and return the largest one.
