Emacs frontend for Igor Chubin's wttr.in weather service https://git.cjennings.net/emacs-wttrin/atom?h=release%2F0.4.0 2026-06-26T14:53:18+00:00 2026-06-26T14:53:18+00:00 Craig Jennings c@cjennings.net 2026-06-26T14:53:18+00:00 urn:sha1:55ee8158a1f85bb532a24d752f9ef409192a924c A saved location carries a display name distinct from its query target ("Mom's House" maps to coordinates or an address), stored in a savehist-persisted wttrin-saved-locations alist. The name shows everywhere the place appears (picker, buffer header, mode-line tooltip) while wttr.in is still queried by the target. Management commands wttrin-save-location, wttrin-rename-location, and wttrin-remove-location edit the directory, with refuse-on-collision rename and a favorite-fallback warning on remove. In the weather buffer, s/r/x reach those commands and d names a detected location before promoting it to the default. The footer is two columns: a "This view" column (another, refresh, quit) and a "Saved locations" column (save, make default, rename, remove). The buffer anchors to the top so the forecast isn't scrolled out of view in a short window. The mode-line follows favorite changes immediately rather than waiting for the next scheduled fetch, and its hover tooltip shows the saved name instead of the raw query. History holds named entries only: raw coordinate detections and saved names stay out of it. 2026-06-24T03:04:46+00:00 Craig Jennings c@cjennings.net 2026-06-24T03:04:46+00:00 urn:sha1:4d46eafaa087f5570ece9d2e5f5d2ba6bc0d824e I added four customizable faces so themes and customize-face can restyle the text wttrin draws itself: wttrin-mode-line-stale (the dimmed stale mode-line emoji), wttrin-staleness-header (the "Last updated:" line), wttrin-instructions (the footer prose), and wttrin-key (the [a]/[g]/[q] chords). The package exposed no faces before and hardcoded one color. The stale-emoji dimming used a literal "gray60". Now it inherits a face, so the color tracks the theme. I changed make-emoji-icon's second argument from a color string to a face symbol applied via :inherit. wttrin-key inherits bold rather than help-key-binding, which is Emacs 28+ while the package supports 24.4. The weather ASCII art stays colored by xterm-color's ANSI faces. Only the package's own text is newly faced. 2026-04-04T18:26:10+00:00 Craig Jennings c@cjennings.net 2026-04-04T18:26:10+00:00 urn:sha1:de99a2930bbe65d7c2ea04656caa18823068c182 The emoji face (dimmed/normal) was frozen at the last update-display call, but the tooltip computes staleness dynamically. Between refreshes, data could cross the stale threshold — tooltip says "Stale" while the emoji is still normal. Track the rendered staleness state. When the tooltip detects a transition, trigger a re-render so the emoji dimming matches. 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". 2026-04-04T17:51:32+00:00 Craig Jennings c@cjennings.net 2026-04-04T17:51:32+00:00 urn:sha1:622ae39ad1e2544980cff73af8a5d5b2a64dacc8 Update copyright headers across all 37 .el files to include 2026. Add missing Author field to testutil-wttrin.el for consistency. 2026-02-21T13:11:03+00:00 Craig Jennings c@cjennings.net 2026-02-21T13:06:50+00:00 urn:sha1:b74b98f177d92d50ddbede900ba41212e07c5f63 Replace TTL-based cache invalidation with proactive scheduled refresh. Both mode-line and buffer systems now follow: timer refreshes cache, display reads from cache, staleness indicated when data is old. Phase 1 - Mode-line cache formalization + staleness display: - Replace wttrin--mode-line-tooltip-data with wttrin--mode-line-cache as (timestamp . data) cons cell matching buffer cache pattern - Add wttrin--format-age helper for human-readable age strings - Rewrite wttrin--mode-line-update-display to take no arguments, read from cache, compute staleness (age > 2x refresh interval), dim emoji gray when stale, show staleness info in tooltip - Rewrite wttrin--mode-line-fetch-weather to write cache on success, show stale display on failure with cache, error placeholder without - Add wttrin--mode-line-update-placeholder-error for first-launch failure Phase 2 - Remove TTL, add proactive buffer refresh: - Rename wttrin-cache-ttl to wttrin-refresh-interval (default 3600s) with define-obsolete-variable-alias for backward compatibility - Change wttrin-mode-line-refresh-interval default from 900 to 3600 - Remove TTL check from wttrin--get-cached-or-fetch; serve cached data regardless of age, background timer keeps it fresh - Add buffer refresh timer (wttrin--buffer-cache-refresh) Phase 3 - Buffer staleness display: - Add wttrin--format-staleness-header for buffer age display - Insert staleness line in wttrin--display-weather before instructions Phase 4 - Cleanup: - Remove all references to wttrin--mode-line-tooltip-data - Update README.org cache settings and mode-line documentation - Update tests for new API (198 tests across 21 files, all passing) 2026-02-20T13:31:41+00:00 Craig Jennings c@cjennings.net 2026-02-20T13:31:41+00:00 urn:sha1:ec8130cfe1a7390e9939b311c8db39907a3f7f44 Display ⏳ with "Fetching weather..." tooltip immediately when mode-line mode starts, so the user sees wttrin is active before the first API response arrives. 2026-02-20T13:06:47+00:00 Craig Jennings c@cjennings.net 2026-02-20T13:06:47+00:00 urn:sha1:30fe3ab230a66f98dd8ece253bf79c61c2fbf6e1 Reject empty or malformed wttr.in responses to prevent blank icon and tooltip. Fix tooltip lambda to treat empty string as falsy. Add debug logging for nil-location and invalid-response paths.
