Release v6.3

weewx-loopdata 6.3

A feature release: $station report tags can now be listed as fields, most
usefully a live WeeWX/server uptime that is correct within a packet or two
of a restart. Drop-in upgrade — install over 6.x, no config changes; new
station.* fields are opt-in via the fields line.

What's new

• Station fields. Any $station report tag can be listed as a field
  with the $ removed: station.uptime.raw,
  station.uptime.long_form(), station.os_uptime.raw,
  station.version, station.location, station.altitude.meter.raw, and
  so on. Values are evaluated against the exact object behind the
  report's $station tag, with loopdata's usual round(n) and format
  specs, so they render as the report would render them.
• Live, restart-correct uptime. uptime and os_uptime are
  recomputed on every loop packet. The report-cycle workaround — shipping
  $station.uptime.raw in a template and extrapolating in page
  javascript — shows the pre-restart uptime still climbing until the next
  report cycle; a station.uptime.raw loop field is correct within one
  packet. Every other $station attribute is constant for the life of
  the weewxd process and is computed once.
• Tuple endpoints render as json arrays. A field whose endpoint is a
  tuple of scalars is now emitted as a json array instead of Python's
  str() of the tuple: station.latitude renders as
  ["37", "24.00", "N"] — the same (degrees, minutes, hemisphere) parts a
  template indexes — and an almanac field ending in, e.g., moon_phases
  gets the same treatment.

Requirements

• WeeWX 4 or 5
• Python 3.7 or later
• No third-party Python packages required
