consistent with how mdoc behaves (and produces more readable manuals).
OK schwarze@

from putting a line break between the '-' and the flag character.

doesn't support the latter. OK schwarze@

Reminded about the missing feature by millert@.
This reduces mandoc/groff differences in base by 25%.

Fixes vertical spacing after "OPTIONS" in gcc(1).

even on an input line containing a partial implicit macro.
Fixes horizontal spacing in vi(1), ddb(4), and ppp(8).

* When they are trailing the last item, move them outside the list.
* When they are trailing any other none-compact item, drop them.
Improves formatting of 40 pages, e.g. grep(1), ksh(1), netstat(1),
ath(4), bsd.port.mk(5), pf.conf(5), mount(8), crypto(9).

that's stupid because it may break enclosing font changes,
but let's do the same for groff bug compatibility.
--> Never use \*(Ba, use just plain "|"! <--
Also, predefined strings are already expanded by the roff(7) parser,
so the mdoc(7) parser has to look for the expanded string.
Formatting improvements in ksh(1), less(1), atan2(3),
hostapd.conf(5), snmpd.conf(5), and mknod(8).

do not let it depend on the default indent provided by -Oindent.
By default, this doesn't change anything because 7 / 2 = 3;
in -Omdoc mode, it makes man(7) output the same as mdoc(7) output.
|
|
In flush-left mode of both man(7) and mdoc(7), when an output line is broken
at the position of a literal tab, the tab indents the following line.

* Keep height argument on the same line (it got printed to the output).
* For .El .sp, avoid the weird .sp -1v .PP .sp output sequence.
|
|
* So far, .Pp and .Lp were removed before paragraph type blocks.
* Now also remove .br before paragraph type blocks.
* Treat .Lp as a paragraph like .Pp, so remove .Pp, .Lp, .br before it.
* Do not treat .sp as a paragraph, don't remove anything before it.
* After .Sh, .Ss, .Pp, and .Lp, remove .Pp, .Lp, .sp, .br, and blank lines.
* After .sp and .br, remove .br.

and ignore .sp after .PP. This fixes vertical spacing
for blank lines after .PP and for .sp after .PP.

of the first list in a section, not before every item of the first list.
|
|
There are still lots of ugly line breaks, to be fixed later.
|
|
body of the item, mdoc(7) breaks the line, whereas the .TP used to
translate this to man(7) does not. Thus, insert an explicit roff(7)
line break in this place.
To be able to correctly count the characters, do not pass font escapes
an the like through print_word().
|
|
In -mdoc -Tman, improve the framework to control vertical spacing.
Use both to support .Bl -compact (surprisingly hard to get right).
|
|
was a non-text node. Fix this by rewriting post_nm() to always set
the meta name to UNKNOWN when the name is missing or unusable.
While here, make MANDOCERR_NONAME an ERROR, as it usually renders
the page content unintelligible.
Bug reported by Maxim <Belooussov at gmail dot com>, thanks.

* .Fn with exactly one argument
* .Bl -hang without a -width
Now all 3776 base manuals build without crashing.
|
|
All mdoc(7) macros are now supported by -Tman.
|
|
|
|
In the end, this turned out to be surprisingly simple;
of course, getting identical output will be quite hard,
so there is no way to quickly set up unit tests.
|
|
while here, do some minor outflags cleanup
|
|
* do not add an excessive blank line before the block
* in literal mode, start a new line after the tag
getting this to work requires some general (print_man_node) fixes:
* in literal mode, break the output line at the end of each
input line, not just after those input lines ending in text
* but don't break it when there was no output on the line
* and adjust the margins after the .HP tag
these general fixes require an adjustment to -Tascii .TP rendering:
* set up NOBREAK mode before the body, not after the head
finally, based on all this, implement -Tman .Bl -hang in terms of .HP
|
|
When the width of a tag in .Bl -hang was exactly one character
shorter than the maximum length that would fit, the following text
would have a negative hang of one character (i.e., hang to the left).
That bug is no longer present in groff-1.21, so relax mandoc, too.
|
|
* fix -Tman .Bl -bullet .It
* adjust the -Tascii .Bl -bullet -dash -hyphen .It
default and minimum width to new groff standards,
it changed from 4n (in groff 1.15) to 2n (in groff 1.21)
* same for -Tascii -enum, it changed from 5n to 2n
* use -hang formatting for -Tascii -enum -width 2n
* for -Tascii -enum, the default is -width 3n
|
|
and implement -Tman .Fd
|
|
|
|
To get the spacing right,
* avoid man(7) code line breaks at places where no spacing is allowed
* allow spacing right after .Sm on
* allow spacing after empty .Fl at the end of an input line

also reset -[no]split mode at .Sh AUTHORS in -Tascii
|
|
shortening some frequent idioms and preparing for better vertical
spacing in the SYNOPSIS; no functional change intended.
|
|
and passing around a structure containing them into each and every function,
just use a single static bitfield.
In preparation for adding more output flags to support more features.
|
|
and fix -Tman .Vt for the non-SYNOPSIS case
|
|
so avoid printing pointless goo in -Tman
|
|
|
|
again, some blank lines still missing from the output.
While here, remove the trailing semicolon
from .Fn when outside .Sh SYNOPSIS.

Needed for sqlite3(1) as reported by espie@.
|
|
The reason was that `RS' wasn't BSCOPE'd, so the next-line (BLINE) scope
opened by `TP' would still be in the macro HEAD.
This was from joerg@'s archive of failures.
Fix by kristaps@, bsd.lv rev. 1.74.

* right after .Ns, avoid breaking the line in man code
* after .Fl without arguments, do not insert a blank into man code
* before each .Nm in .Sh SYNOPSIS, insert a .br into man code
* skip .Pp arguments, don't copy them to man code
