* parser bugs

************************************************************************

- It should be noted that in mandoc, the TBL macros are interpreted as

real roff macros (e.g., `. TS' is ok), while the troff preprocessor

only looks for `.TS' (static string). This should be noted in the

COMPATIBILITY section. The same applies for nascent `.EQ' (as it is

now, `.EN' is processed as a static string).

- .TP before .SH is still FATAL in man(7)

reported by brad@ Sat, 15 Jan 2011 15:54:54 -0500

- The mdoc(7) parser should handle `\.' as punctuation:

.Ql .if ${VAR} op something \.

should produce

`.if ${VAR} op something'.

not

`.if ${VAR} op something .'

as seen in make(1).

To escape the dot, one would use `\&.'.

- the roff parser doesn't tolerate additional characters between

a macro and the \} terminating a conditional block, e.g.

.if n \{

.br \}

--- missing roff features ----------------------------------------------

- roff.c should treat \n(.H>23 and \n(.V>19 in the pod2man(1)

preamble as true, see for example AUTHORS in MooseX::Getopt.3p

reported by Andreas Voegele <mail at andreasvoegele dot com>

- .ad (adjust margins)

.ad l -- adjust left margin only (flush left)

.ad r -- adjust right margin only (flush right)

- xloadimage(1) wants .ti (temporary indent), rep by naddy@

reported again by bentley@ in nmh(1) Mon, 23 Apr 2012 13:38:28 -0600

also uses .ce (center N lines) and .fc (field control)

- .ta (tab settings) occurs in ircbug(1) and probably gnats(1)

reported by brad@ Sat, 15 Jan 2011 15:50:51 -0500

- pod2man expects `tr' to be implemented for \*(-- to work

- \c (interrupted text) should prevent the line break

even inside .Bd literal; that occurs in chat(8)

- \c (interrupted text) occurs in chat(8)

- using undefined strings or macros defines them to be empty

--- missing mdoc features ----------------------------------------------

Line 101

Line 78

- explicitly disallow nested `Bl -column', which would clobber internal

flags defined for struct mdoc_macro

- In .Bl -column .It, the end of the line probably has to be regarded

as an implicit .Ta, if there could be one, see the following mildly

ugly code from login.conf(5):

.Bl -column minpasswordlen program xetcxmotd

.It path Ta path Ta value of Dv _PATH_DEFPATH

.br

Default search path.

reported by Michal Mazurek <akfaew at jasminek dot net>

via jmc@ Thu, 7 Apr 2011 16:00:53 +0059

- inside `.Bl -column' phrases, punctuation is handled like normal

text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."

Line 116

Line 103

(e.g., NetBSD mDNSShared/dns-sd.1)

(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)

- When there is free text in the SYNOPSIS and that free text contains

the .Nm macro, groff somehow understands to treat the .Nm as an in-line

macro, while mandoc treats it as a block macro and breaks the line.

No idea how the logic for distinguishing in-line and block instances

should be, needs investigation.

--- missing man features -----------------------------------------------

- bashbug(1) complains "line scope broken" after

.SM

.B something

should either just work or be a warning

reported by naddy@

- groff an-ext.tmac macros (.UR, .UE) occur in xine(5)

reported by brad@ Sat, 15 Jan 2011 15:45:23 -0500

- -T[x]html doesn't stipulate non-collapsing spaces in literal mode

--- missing tbl features -----------------------------------------------

- implement basic non-parametric .de to support e.g. sox(1)

reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200

*** sox(1) still doesn't work, tbl(1) errors need investigation

- allow standalone `.' to be interpreted as an end-of-layout

delimiter instead of being thrown away as a no-op roff line

reported by Yuri Pankov, Wed 18 May 2011 11:34:59 CEST

--- missing misc features ----------------------------------------------

- clean up escape sequence handling, creating three classes:

Line 174

Line 169

so far, we only have it in roff(7) and man(7)

reminded by millert@ Thu, 09 Dec 2010 17:29:52 -0500

- perl(1) SYNOPSIS looks bad; reported by deraadt@

1) man(7) seems to need SYNOPSIS .Nm blocks, too

- In .Bl -column,

.It Em Authentication<tab>Key Length

ought to render "Key Length" with emphasis, too,

see OpenBSD iked.conf(5).

reported again Nicolas Joly via wiz@ Wed, 12 Oct 2011 00:20:00 +0200

- empty phrases in .Bl column produce too few blanks

try e.g. .Bl -column It Ta Ta

is just "o\bo".

see for example OpenBSD ksh(1)

- The characters "|" and "\*(Ba" should never be bold,

- .Pp between two .It in .Bl -column should produce one,

not even in the middle of a word, e.g. ".Cm b\*(Bac" in

not two blank lines, see e.g. login.conf(5).

"mknod [-m mode] name b|c major minor"

reported by jmc@ Sun, 17 Apr 2011 14:04:58 +0059

in OpenBSD ksh(1)

reported again by sthen@ Wed, 18 Jan 2012 02:09:39 +0000 (UTC)

- A bogus .Pp between two .It must not produce a double blank line,

see between -R and -r in OpenBSD rm(1), before "update" in mount(8),

or in DIAGNOSTICS in init(8), or before "is always true" in ksh(1).

The same happens with .Pp just before .El, see bgpd.conf(5).

Also have `It' complain if `Pp' is invoked at certain times (not

-compact?).

- If the *first* line after .It is .Pp, break the line right after

the tag, do not pad with space characters before breaking.

See the description of the a, c, and i commands in sed(1).

Line 243

Line 229

.Bl -tag -width ".Dv message"

in magic(5), located in src/usr.bin/file, is the same

as -width 7n, not -width 11n.

The same applies to .Bl -column column widths;

reported again by Nicolas Joly Thu, 1 Mar 2012 13:41:26 +0100 via wiz@ 5 Mar

- The \& zero-width character counts as output.

That is, when it is alone on a line between two .Pp,

Line 251

Line 239

- When .Fn arguments exceed one output line, all but the first

should be indented, see e.g. rpc(3);

reported by jmc@ on discuss@ Fri, 29 Oct 2010 13:48:33 +0100

reported again by Nicolas Joly via wiz@ Sun, 18 Sep 2011 18:24:40 +0200

Also, we don't want to break the line within the argument of:

.Fa "chtype tl"

- .Ns should work when called at the end of an input line, see

the following code in vi(1):

.It Xo

.Op Ar line

.Cm a Ns Op Cm ppend Ns

.Op Cm !\&

.Xc

The input text is appended after the specified line.

- Header lines of excessive length:

Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c

and document it in mdoc(7) and man(7) COMPATIBILITY

found while talking to Chris Bennett

- In man(7), the sequence

.HP

.SH HEADER

one line of regular text

.SH

.PP

should not produce two blank lines before the .SH,

regular text

see for example named-checkconf(8).

should not produce any blank lines between the header and the text,

see for example rsync(1).

Reported by naddy@ Mon, 28 Mar 2011 20:45:42 +0200

- In man(7), the sequence

regular text

.RS

.IP

should have a blank line between the text and the beginning of the

.IP "tag"

indented paragraph, see for example sudo(1).

indented text

should produce one, not four blank lines between the regular text

and the tag, see for example rsync(1).

Likewise,

regular text

.IP

indented text

should produce one, not two blank lines in between, and

regular text

.IP

.RS

.IP tag

indented text

should produce one, not three blank lines.

Reported by naddy@ Mon, 28 Mar 2011 20:45:42 +0200

- At least sometimes, .sp is ignored right after .SH; see named.conf(5).

- trailing whitespace must be ignored even when followed by a font escape,

see for example

makes

Line 290

Line 285

in dig(1).

- the PDF file is HUGE: this can be reduced by using relative offsets

- instead of re-initialising the roff predefined-strings set before each

parse, create a read-only version the first time and copy it

************************************************************************

************************************************************************

- We use the input line number at several places to distinguish

same-line from different-line input. That plainly doesn't work

with user-defined macros, leading to random breakage.

- Find better ways to prevent endless loops

in roff(7) macro and string expansion.

- Finish cleanup of date handling.

Decide which formats should be recognized where.

Update both mdoc(7) and man(7) documentation.
