Here's a comparison among:
- the current seconds-to-string
- mastodon-tl--human-duration
- mastodon with a 3600s resolution
- mastodon with 1yr "resolution"
- the new seconds-to-string with option READABLE=t
- new seconds-to-string with abbreviated units and half unit resolution
<snip>
Basically, this shows that:
. mastodon truncates where seconds-to-string rounds
I definitely think rounding makes more sense for a readable unit; consider 2.98y.
. seconds-to-string lacks the "1 hour 11 min" output format
. seconds-to-string sometimes produces inaccurate results, as in
5.5 => 5.48s
The last item worries me: can we fix this, please?
The latter issue results simply from my truncation of the initial delay column to 1 decimal digit. E.g. .45s * 2.3^3 = 5.47515s, so s2s has it right.
The second item sounds like a useful feature, so maybe an optional
behavior could provide it as well?
I've expanded the call format to (delay &optional readable abbrev half) , with READABLE='expanded an option to get the "1 hour 11 min" expanded format, i.e. one larger and one smaller unit (if appropriate). Patch below.
Updated output at the same delays for the various new options (r: readable, e: readable=expanded, a: abbrev, h: half):
