Hi Branden, I had a typo in a man(7) page where for some reason I slipped an .IP in the wrong place. I had no warnings about that IP. Neither groff(1) nor mandoc(1) complained about it. And BTW, mandoc(1)'s behavior seems the right one to me.
We're lucky that this is not a regression, since groff-1.22.4 is
crappier (it has the same bug, and it even blows me with blank lines
in other unwanted places).
Here's the source:
cat missing_blank.man
.TH a s d f
.SH qwe
rty.
.IP \[bu] 3
asd.
.PD 0
.IP \[bu] 3
fgh.
.IP
.PD
.SH jkl
zxc.
And here's what different formatters have to say about it:
$ /usr/bin/groff -ww -man -Tutf8 ./missing_blank.man
a(s) a(s)
qwe
rty.
• asd.
• fgh.
jkl
zxc.
f d a(s)
$ /usr/local/bin/groff -ww -rCHECKSTYLE=3 -man -Tutf8 ./missing_blank.man
an.tmac:./missing_blank.man:1: style: .TH missing fifth argument and second
argument 's' not a recognized manual section; specify its title
an.tmac:./missing_blank.man:6: style: use of deprecated macro: .PD
an.tmac:./missing_blank.man:10: style: use of deprecated macro: .PD
a(s) a(s)
qwe
rty.
• asd.
• fgh.
jkl
zxc.
f d a(s)
$ mandoc -Tlint ./missing_blank.man
mandoc: ./missing_blank.man:1:5: STYLE: lower case character in document title:
TH a
mandoc: ./missing_blank.man:1:9: WARNING: cannot parse date, using it verbatim:
TH d
$ mandoc -man ./missing_blank.man
a(s) a(s)
qwe
rty.
• asd.
• fgh.
jkl
zxc.
f d a(s)
We can see how mandoc(1), even if it doesn't warn about an ignored IP,
it correctly puts a blank before "jkl".
Cheers,
Alex
