Hi, it looks like somewhere between 2.7.5 and 2.8.5, man-db stopped honouring
a locally added '-U' option in manpath.config:
banana$ grep ^DEFINE /etc/manpath.config
DEFINE troff groff -U -mandoc
DEFINE nroff nroff -U -mandoc
banana$
Was this change of behaviour deliberate? Or is there an alternative way to
get .pso in man page sources working again? (Yes, I really need .pso.)
I checked the changelog entries from 2.7.5 to 2.8.5 but don't see any obvious
change that caused this change in behaviour.
If I call groff directly with 'groff -man -Tascii -U ./lx.1' then it works.
Thanks!
Alexis
PS Below is a demonstration of the problem with 2.8.5 and it working on 2.7.5.
With 2.8.5:
I have a command ade-config available, which just outputs some
variable settings in manpage-compatible format:
banana$ /usr/bin/ade-config --format=man
.ds ade_prefix /usr
.ds ade_lib_prefix /usr/lib/ade
...
banana$
and I have a man page source:
banana$ cat lx.1
.pso ade-config --format=man
.TH LX 1 "25 Apr 2019"
.SH NAME
lx \- do something in \*[ade_lib_prefix]
.br
.ne 5
.SH SYNOPSIS
.B lx
...
banana$
Yet when I run 'man ./lx.1' (or with lx.1 in a more normal place)
the stdout is (with blanks squeezed):
banana$ man ./lx.1 | sed -r 's/[ \t]+/ /g'
LX(1) General Commands Manual LX(1)
NAME
lx - do something in
SYNOPSIS
lx
25 Apr 2019 LX(1)
banana$
I.e. the fourth line is missing the text "/usr/lib/ade".
stderr is empty:
banana$ export MAN_KEEP_STDERR=1
banana$ man ./lx.1 > /dev/null
banana$
'man -d' shows no obvious errors but does show that the '-U' has
been seen:
banana$ man -d ./lx.1 2>&1 > /dev/null | fgrep -- -U
Defined `troff' as `groff -U -mandoc'.
Defined `nroff' as `nroff -U -mandoc'.
`troff' `groff -U -mandoc' `-3'
`nroff' `nroff -U -mandoc' `-3'
banana$
Exporting 'MANROFFOPT=-U' also did not restore the old bahaviour.
With 2.7.5 (on Ubuntu 16.04) the output from 'man ./lx.1' is:
cercis$ man ./lx.1 | sed -r 's/[ \t]+/ /g'
LX(1) General Commands Manual LX(1)
NAME
lx - do something in /usr/lib/ade
SYNOPSIS
lx
25 Apr 2019 LX(1)
cercis$
I.e. the fourth line *has* the text "/usr/lib/ade".
