Emacs frontend for Igor Chubin's wttr.in weather service https://git.cjennings.net/emacs-wttrin/atom?h=release%2F0.4.0 2026-06-25T16:15:34+00:00 2026-06-25T16:15:34+00:00 Craig Jennings c@cjennings.net 2026-06-25T16:15:34+00:00 urn:sha1:33621b5a6e5407da190767b89756e287698ef234 Geolocation used to live in a separate command, so getting weather for where you are meant knowing a second command existed. I added a "Current location (detect)" entry pinned to the top of the M-x wttrin picker. Selecting it detects your location and shows its weather. If the guess is wrong (VPN, hotspot) the detected city is visible in the header, so you reopen the picker and type one. Press d to keep the detected city as the default. The entry is pinned first through a completion table whose display-sort-function holds against completion frameworks that re-sort, and it never enters location history or the cache as a place. A new wttrin-geolocation-enabled (default t) turns every geolocation surface off for users who want that: the picker entry, the auto-detect favorite, and the command. It stays on by default. The older wttrin-set-location-from-geolocation command is now obsolete in favor of the picker. Its customize-save-variable persistence advice is replaced by savehist, which already carries the favorite across sessions. 2026-06-25T05:10:49+00:00 Craig Jennings c@cjennings.net 2026-06-25T05:10:49+00:00 urn:sha1:4266923daf6f137fbe2897334b7669f7fb4633c8 Pressing d to promote a displayed location to the favorite changed wttrin-favorite-location but left the mode-line untouched. Its cache still held the old location's weather. The next scheduled refetch could be up to an hour away, so the hover tooltip kept showing the previous default. wttrin--set-favorite-location now detects a real change and, when the mode-line is active, clears the stale cache and fetches the new location at once via a new wttrin--mode-line-refresh-now helper. The tooltip switches within seconds instead of waiting for the timer. 2026-06-24T04:10:51+00:00 Craig Jennings c@cjennings.net 2026-06-24T04:10:51+00:00 urn:sha1:efd3cdce5b3aebfdb3e02460d1ec0434cef85949 I bound d in the weather buffer to wttrin-make-default, which sets wttrin-favorite-location to the location on screen so it drives the mode-line and future sessions. The footer advertises "[d] to make default". Persistence rides savehist, not the Emacs custom-variable mechanism: wttrin--savehist-register registers wttrin-favorite-location alongside the search history, at load and on savehist-save-hook. Enable savehist-mode and the favorite survives restarts. Promoting a location drops it from the search history, the way wttrin-default-locations entries are kept out of history. The favorite shows in the picker instead: wttrin--completion-candidates prepends it when it's a string and not already a default, so it appears exactly once. The setter only assigns the variable and trims history. It doesn't register with savehist itself, because savehist-additional-variables is unbound until savehist loads, so a direct add-to-list would error for users without savehist. Registration stays on the load and save-hook path.
