Release v6.9

weewx-loopdata 6.9

A next_* almanac field now expires the moment its event passes,
instead of serving the same event until midnight; complete Italian,
Norwegian (Bokmål) and Swedish translations of the sample report ship,
all three Beta pending native-speaker review; and almanac fields no
longer cache a no-data answer for the rest of the day. Drop-in
upgrade — install over 6.x; no configuration changes, and every
existing fields line keeps its meaning (next_* fields simply stop
serving events that have already happened). Released alongside
weewx-skyfield 2.0 and weewx-celestial 8.0, which ship the same three
languages for their pages — and whose satellite pass panel this
release's expiry fix keeps honest.

What's new

• next_* almanac fields expire at their event's own instant, not
  at midnight. Fields naming the same event — say a satellite
  pass's rise, set and maximum altitude — are computed together and
  expire together, at the latest time among them (for a pass, the set
  time): an in-progress pass keeps serving until it ends, then the
  very next packet carries the following pass, every field switching
  at once. Before, the day's first packet computed the event once and
  served it until the local day rolled — a stale window in every
  release since almanac fields shipped in 5.0 (almanac.next_full_moon
  served the old event from the instant it passed until midnight), made
  glaring by developing weewx-celestial 8.0's "Next pass overhead"
  panel against this code: driven by the old caching, the panel showed
  a morning pass as "just set" until the day's end. Fixed before
  either shipped. Recomputes stay rare by construction, since each one returns
  the next occurrence, re-arming the cache: next_full_moon
  recomputes once per lunar month, a satellite's next_pass once per
  pass. previous_* fields and the day tier are unchanged, and a
  group with no time-typed field keeps the once-per-day refresh —
  include a pass time field to get event-time expiry.

• Italian ships (Beta). lang/it.conf — gauge headings after
  WeeWX's own Seasons skin (Punto di rugiada, Pressione, Pioggia,
  Intensità pioggia), with one documented departure (Temperatura
  percepita for Feels Like, the term Italian weather services use);
  the nine trend.barometer.desc tendency descriptions in bulletin
  vocabulary (in aumento, stabile, in diminuzione); and, for a
  loopdata instance whose target report is Italian, the compass
  ordinates (O for west, SSO for SSW, N.D. for no direction), moon
  phases, body and all 88 constellation names. Select it with
  lang = it on the report's stanza.

  

• Norwegian ships (Beta). lang/no.conf (Bokmål; the file code is
  WeeWX's own no) — gauge headings after Seasons' Norwegian
  (Lufttrykk, Regn, Regnintensitet, Føles som), with the
  departures documented in the file header; tendencies stigende /
  stabilt / fallende; and the value-side sections for a Norwegian
  target report (Ø for east, SSV for SSW). Select it with lang = no.

  

• Swedish ships (Beta). lang/sv.conf — WeeWX's Seasons skin has
  no Swedish file, so the headings are fresh in SMHI's everyday
  vocabulary (Daggpunkt, Lufttryck, Regnintensitet, Känns som);
  tendencies stigande / stabilt / fallande; and the value-side
  sections for a Swedish target report — coordinates abbreviate east as
  Ö while the compass winds use O (NNO, ONO, OSO, SSO). Select it with
  lang = sv.

  

• In all three, the shared vocabulary — body names, moon phases,
  hemispheres, compass ordinates, all 88 constellation names — is
  copied verbatim from weewx-skyfield's and weewx-celestial's new lang
  files, kept in step by the same cross-repo test that pins the German,
  French, Danish, Dutch and Spanish. Corrections from native speakers
  are very welcome at
  the issue tracker.

• No-data almanac answers are no longer cached for the day. A day-
  or event-tier almanac field that evaluates to no data — say, a
  weewx-skyfield satellite whose orbital elements have not been
  downloaded yet — now retries on every packet and picks up its value
  the moment the almanac has data. Before, the honest startup N/A was
  cached until midnight, long after the elements arrived. Fields with
  real values cache exactly as before.

Requirements

• WeeWX 4 or 5 (translations need WeeWX 4.6 or later)
• Python 3.7 or later
• No third-party Python packages required
• Satellite almanac fields (almanac.iss.next_pass... and friends, as
  weewx-celestial 8.0's migrator emits them) need
  weewx-skyfield 2.0
  registered as the almanac; every other almanac field works with
  PyEphem or WeeWX's built-in almanac, as always
