Hi,
What do people think about the attached patch, which teaches ncal(1)
(and cal(1)) to parse month names if invoked with both a month and year
specification? It is not terribly necessary, but it just might turn out
to be useful :)
Examples:
[roam@straylight:v2 ~]$ LANG=C ncal August 2002
August 2002
Mo 5 12 19 26
Tu 6 13 20 27
We 7 14 21 28
Th 1 8 15 22 29
Fr 2 9 16 23 30
Sa 3 10 17 24 31
Su 4 11 18 25
[roam@straylight:v2 ~]$ LANG=C cal sep 2001
September 2001
Su Mo Tu We Th Fr Sa
1
2 3 4 5 6 7 8
9 10 11 12 13 14 15
16 17 18 19 20 21 22
23 24 25 26 27 28 29
30
[roam@straylight:v2 ~]$
(warning: Windows-1251 character set in the following example)
[roam@straylight:v2 ~]$ cal фев 2000
Февруари 2000
Нд Пн Вт Ср Чт Пт Сб
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29
[roam@straylight:v2 ~]$
G'luck,
Peter

because I didn't think of a good beginning of it.
