Hi Manuel,
my goal was pretty simply: I wanted the output be nicely aligned even when
it's piped. When I tried that using -F I thought that -F is just ignored.
However, as you have shown that is not the case.
Nevertheless, it seems that setting the width of columns does not work as I
expected:
That's because it acts as --disable-columns, so widths are ignored in
that case.
Perhaps I'm still not understanding how to correctly use this? Is there a
way to have `aptitude search '~N' | head -3` produce aligned output?
Right now the only solution I see is something ugly like the following
# aptitude -F '%p %d' search '~N' | perl -ne 'printf("%-30s - %s\n", /(\S+)
(.+)/)' | head -3
icingacli - simple CLI tool for Icingaweb2 and its
modules
icingaweb2-common - simple and responsive web interface for
Icinga - common files
libp8-platform-dev - Pulse-Eight's platform support library --
development files
Right.
So if you want to parse the different fields, the "machine-parsable"
that you mentioned, I think that it's better to use "-F '%p ΒΆ %d'", with
some strange separator character that does not appear in the
descriptions (although I wonder if there's a way to really guarantee
that... perhaps control characters).
For getting aligned output when piping/redirecting and you want to set a
width anyway, I made it to "columnize" and using -w/::Width when set
explicitly instead of "--disabling-columns".
It still acts as "--disabling-columns" if width not set explicitly
(because it cannot be guessed correctly in that case).
So "`aptitude search -w $COLUMNS > t; less t` worked in 0.7.4", should
work again in > 0.7.6.
Marking as +pending.

Actually I started to like the perl post-processing, so I will simply close
my bug report although I'm still not understanding why the width in the
format does not work in piped context.
It's probably more useful for a range of use-cases, yes.
Anyway, changed now in the case that you or anybody else still want to
use the functionality.
Cheers.
