Emacs frontend for Igor Chubin's wttr.in weather service https://git.cjennings.net/emacs-wttrin/atom?h=v0.3.0 2026-04-04T18:07:50+00:00 2026-04-04T18:07:50+00:00 Craig Jennings c@cjennings.net 2026-04-04T18:07:50+00:00 urn:sha1:f526cf641181e9cdb533a1f8a278de1fad49ca25 The tooltip was a static string computed at fetch time. Since every successful fetch sets the cache timestamp to now and immediately renders the tooltip, it was always "just now". Extract wttrin--mode-line-tooltip as a named function that computes age from the cache at call time. Set help-echo to this function so Emacs invokes it on hover, producing an accurate age like "Updated 12 minutes ago".
