* parser bugs

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

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

- ".\}" on its own line gets translated to bare ".\&"

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

which forces pset() into man(7)

and then triggers an unknown macro error

reported by naddy@ Sun, 3 Jul 2011 21:52:24 +0200

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

- .It is parsed in general, except in .Bl -diag

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

deraadt@ Mon, 07 Nov 2011 11:10:52 -0700

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 \}

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

* formatter bugs

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

- tbl(7): Horizontal and vertical lines are formatted badly:

With the box option, there is too much white space at the end of cells.

Horizontal lines from "=" lines are a bit too long.

* missing features

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

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

- .if n \{

.br\}

should cause an extra space to be raised.

- .ad (adjust margins)

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

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

Line 56

Line 55

- .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) occurs in chat(8)

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

Line 95

Line 92

- 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.

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

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

Line 110

Line 117

(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 175

Line 190

.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

Line 193

Line 209

- .Rv (and probably .Ex) print different text if an `Nm' has been named

Line 216

Line 232

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

-compact?).

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

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

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

- 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 245

Line 265

- 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 only be effective when called by another macro,

not as a stand-alone macro at the beginning of a line;

see for example the awk(1) SYNOPSIS.

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

the following code in vi(1):

.It Xo

Line 272

Line 291

see for example named-checkconf(8).

- In man(7), the sequence

.SH HEADER

.PP

regular text

.RS

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

.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 303 Several areas can be cleaned up to make mandoc even fa

Line 342 Several areas can be cleaned up to make mandoc even fa

- 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

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

* structural issues

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

- 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.
