Package: bsdmainutils
Version: 9.0.6
Severity: minor
With the -w flag, ncal shows the number of the week:
pseyfert@robusta ~ > LC_ALL=C ncal -w
January 2017
Su 1 8 15 22 29
Mo 2 9 16 23 30
Tu 3 10 17 24 31
We 4 11 18 25
Th 5 12 19 26
Fr 6 13 20 27
Sa 7 14 21 28
1 2 3 4 5
with -b it prints days row wise instead of column wise:
pseyfert@robusta ~ > LC_ALL=C ncal -b
January 2017
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 31
yet the combination of both flags doesn't lead to the number of the week being
shown at the beginning of each row:
pseyfert@robusta ~ > LC_ALL=C ncal -b -w
January 2017
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 31
In the attached patch I added this feature (which is a bit hacky as `weekstart`
gets incremented and decremented constantly)
