This is good, but there's a challenge: how does this interact with localization?

• eg: make sure to mark the text as left to right in case the parent page isn't
• eg: we might want to use a localized date format
• other ideas can fit too
  /area web-development

nit: this is mildly deceptive

Thanks for the feedback! Here's what we can do:

• Add dir and lang attributes on the shortcode to handle text direction
• Use Hugo's i18n for region name translations
• For dates, we can keep the original format for now, but it's possible to parse dates in the script and use Hugo's time formatting

other suggestions are welcome too

LGTM!

@Caesarsage, Thank you. This is a solid implementation that eliminates the need for manual event updates. The filtering logic and error handling are particularly well done.

Non-blocking: This could also use CLI flags for URL/limit/output to help with local testing, but the current constant-based approach is also reasonable for a small maintenance script.

This idea seems interesting :)

@Caesarsage

* Use Hugo's i18n for region name translations

region name - does it mean country name and city name ?

for example in:

        <a href="https://events.linuxfoundation.org/kubecon-cloudnativecon-north-america/" class="desktopKCButton"><strong>North America</strong> (Atlanta, Nov 10-13)</a>

there is "North America" + "Atlanta".

[lmktfy]

I'd say that the region is "North America". KubeCon North America was most recently held in the city of Atlanta.

Either before or after we merge this, we could ask the CNCF for a more machine readable version of the page we scrape.

Maybe there is a WordPress plugin that can add RDFa data to the event feed or something? Or they can serve the data we're after as jCalendar?

Yes, i agree with this

How do one get this informations from CNCF

[lmktfy]

To contact the CNCF, we use https://github.com/cncf/servicedesk

@kubernetes/sig-docs-leads can send a message on your / our behalf @Caesarsage (and it's OK to propose that!)

[nate-double-u]

Thanks for this @Caesarsage

A concern: this may circumvent the steering committee's ability to approve site-wide changes. Usually any update to the banner needs to be approved. Tho, I suppose if this is run and generates a PR that could be approved that would alleviate the concern.

Also, each banner has a UTM link associated with it generated by the LF Marketing team that wouldn't be captured by scraping the event page.

How would this manage scheduling the banners (and ensure there is no overlap between existing banners, or if there is, how would this decide which has precedence)?

[lmktfy]

There are several places we mention KubeCon.

This PR is about mentioning it on https://k8s.io/ (and localized equivalents)

We also have site wide banners, that this PR doesn't plan to touch.

For an Urchin / Google Analytics string, we could put that into a Netlify variable and inject it into production builds. The string isn't secret but putting it into a variable helps avoid tainting the metrics with forks and stale site.
