Emacs frontend for Igor Chubin's wttr.in weather service https://git.cjennings.net/emacs-wttrin/atom?h=v0.3.1 2026-04-04T18:26:10+00:00 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.
