Subject: [9front] cmd/cal: fix days of week alignment for year view (patch)
Date: Sat, 19 Jun 2021 00:34:06 +0200 [thread overview]
Message-ID: <4813B9A38B4F2483B8CEB8EC70C9CA96@9lab.org> (raw)
Inline below is a patch fixing the alignment of the rows
printing days of the week when viewing the whole year.

25 26 27 28 29 30 31 29 30 31
…
Note how the days (i.e. ' M Tu W Th F Sa Su') for Feb and Mar
do not align with the day numbers.
This is because an extra space is left *before* adding the terminating
'\0' via the pointer `dayw`.
With the patch applied the calendar aligns nicely for the year view:
