WeeWX 4.10.1 deltatime, long_form and current

[Werner Krenn]

before 4.10.1
$current.runtime        18 Tage, 0 Stunden, 18 Minuten

with 4.10.1
$current.runtime        1556294 Sekunden
$current.runtime.hour        432,3 Stunden
$current.runtime.day        18,0 Tage
$current.runtime.long_form    18 Minuten, 14 Sekunden     #missing days and hours!

temporary solution:
in weewx.conf
[StdReport]
    [[Defaults]]
        [[[Units]]]
            [[[[DeltaTimeFormats]]]]
                current = "%(day)d Tage, %(hour)d Stunden, %(minute)d Minuten"        Labels are Text

with
                current   = "%(day)d%(day_label)s, %(hour)d%(hour_label)s, %(minute)d%(minute_label)s"
weewx[11327] ERROR weewx.reportengine: Syntax error: missing option "day_label" in interpolation.
weewx[11327] ERROR weewx.reportengine:    ****       Report ignored

Is there another solution?

NO.

@Tom,

You assume that the current deltatime value is always less than 1 hour,
otherwise the default definition of
current = "%(minute)d%(minute_label)s, %(second)d%(second_label)s"
makes no sense.

You can now redefine this in weewx.conf or %lang.conf:
current = "%(day)d%(day_label)s, %(hour)d%(hour_label)s, %(minute)d%(minute_label)s".
But with that, you get an error when starting the report:

ERROR weewx.reportengine: Syntax error: missing option "day_label" in interpolation.

If you then change this definition without the '_labels', e.g.;
current = "%(day)d days, %(hour)d hours, %(minute)d minutes".
Then it works, but you lose the foreign language support.
I have now changed the units.py and in
    def long_form(self, val_t, context, format_string=None):
I now differentiate between less than 3600 seconds and less than 86400 seconds and then greater.

@Tom,

You assume that the current deltatime value is always less than 1 hour,

 

I'm not assuming anything. You are using the tag $current, which implies something that is, well, "Current." That is, it is of a time scale comparable to an archive interval or, perhaps, up to a day. Definitely not longer than that.

It can't guess your intentions, nor can it guess that "runtime" might be measured in days. If it can, then tell it that:

$current.runtime.long_form(format_string="%(day)d%(day_label)s, %(hour)d%(hour_label)s, %(minute)d%(minute_label)s")

The reason why it's done this way is so that you don't end up with a leading "0 days" for the typically short time intervals associated with $current.

An alternative is to define a search list extension for "runtime". Then you can apply any context you wish, not just the "current" context.

Hope this helps.
