Re: [mapserver-users] [Feature Request] Ability to extract capture group contents from regex validation
This sounds like a good idea to me, but I would suggest to use named
capture groups. In perl, this uses this syntax: (?pattern). So,
in this example, it could be:
"datetime" "^(?[0-9]{4})[-_](?[0-9]{2})[-_](?[0-9]{2})$" # <-
3 capture groups
And the result could then be used in substitution as: %year%, %month%
and %day%. Maybe with an added prefix, but I'd prefer without, tbh.

Hi. I'm doing exactly this. Although, I'm not using mod_rewrite, instead I have a mod_perl module as a URI Translation handler, but it's essentially doing exactly the same thing as a regular rewrite. This works reasonably well, but I wouldn't mind if this functionality was baked into the mapfile. Especially since this could then be easily applied to other temporal dimensions than just TIME. -- Trond Michelsen ___ mapserver-users mailing list mapserver-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Next MapServer project steering committe meeting: Thursday 13:00UTC
Hi everyone!
This is not usual, but here it goes...
We all know that MapServer has a vibrant user community (and sometimes
development is not as visible or discussed as in other projects), so
(unofficially) I'd like to mention here that the MapServer Project Steering
Committee ("PSC", that means the 10+ individuals who help make decisions
regarding the management of MapServer releases and code changes) will be
meeting this coming Thursday on IRC chat. You are also encouraged to join the
meeting (there is an agenda item near the end called "community feedback",
where you can give input on what's important or missing in the upcoming 8.0
release, etc). Join and share! That's what FOSS is all about. Thanks!
- time:
- 13:00 UTC (8am Minny, 3pm Paris)

- agenda: https://github.com/MapServer/MapServer/wiki/PSC-Meeting-2021-07-29
- location: the meeting will be held in the #mapserver channel at

[mapserver-users] Please add your site (or OGC services) to the MapServer Gallery
Hi everyone! A few years ago a new MapServer user reminded us that we need working examples of applications (and MapServer-driven WMS/WFS/OWS services) listed on our map gallery. Please take a minute to add your site and specs (respecting the syntax and alphabetical order) at: https://github.com/mapserver/mapserver/wiki/MapServer-Site-Gallery It has become a great resource! Please take a moment to make sure that your MapServer-driven site or OGC services are listed there, especially as we are getting closer to the big MapServer 8.0 release. So help show off the powers of MapServer!! Thank you everyone :) -jeff -- Jeff McKenna GatewayGeo: Developers of MS4W, MapServer Consulting and Training co-founder of FOSS4G http://gatewaygeo.com/ ___ mapserver-users mailing list mapserver-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapserver-users
