Re: [nmh-workers] Ordinal Indicators.
Hi kre, > LC_TIME says how time (of day) is represented (d/m/y m/d/y, 12 or 24 > hour, etc) I had a need today to have date(1) produce ‘8th’ for today and find its interpreted sequences don't support the https://en.wikipedia.org/wiki/Ordinal_indicator, but then neither does POSIX's LC_TIME, it seems. -- Cheers, Ralph. -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers

Yes, strftime() has no ordinals, and (as best I understand it) locales
don't either. To get them you need to code it yourself
D=$(date +%d)
case "$D" in
[023]1) ORD=st;;
[02]2) ORD=nd;;
[02]3) ORD=rd;;
*) ORD=th;;
esac
case "$D" in
0*) SP=;;
*) SP=' ';;
esac
and then deal with internationalising that for yourself... (good luck).
Then
date "+%A, the${SP}%e${ORD} of %B"
or whatever.

This is true. To correct that, I note mh-format(5) too has no function to produce the ordinal suffix. :-) -- Cheers, Ralph. -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers

Impressively quick work.

Yep, you certainly made it look easy compared to kre and me. And it saved me raising a bug to say it wasn't implemented.

Re: [nmh-workers] Ordinal Indicators.
Ken, Ralph is being overly subtle (or perhaps I could use another word...) The point is, that if you're going to add this, you should do it correctly, not just any random code that looks close. kre ps: Hint: 11st is not correct. -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers

>The point is, that if you're going to add this, you should do it >correctly, not just any random code that looks close. Geez, you could have just SAID that (ok, fine, you DID say that, but ... oh, never mind). I missed that part in your examples.

Re: [nmh-workers] Ordinal Indicators.
Hi,
Is -42nd handled? IIRC we demand C99 so we know rounding is towards
zero. But C's remainder operator, ‘%’, returns the sign of the
dividend, unlike modulo. And then there's two's complement so INT_MIN
can't be made positive.

%%${b}10 = %(modulo${b}10)" ''
> done
> done
-42 / -10 = 4 -42 % -10 = -2
-42 / 10 = -4 -42 % 10 = -2
42 / -10 = -4 42 % -10 = 2
42 / 10 = 4 42 % 10 = 2

Hi Valdis, > > Is -42nd handled? > > I admit being totally mystified as to what situations require proper > handling of negative ordinals Well, from here the one after next is the 2nd, and the one before last is the -2nd. Regardless, the code and documentation should match, and it seems easiest to fix the code rather than explain the exceptions in the man page. IIRC that was the impetus behind McIlroy adding the BUGS section; his peers found it simpler to fix than document. -- Cheers, Ralph. -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
