************************************************************************
* Official mandoc TODO.
* $Id: TODO,v 1.58 2010/10/01 21:51:13 schwarze Exp $
************************************************************************
************************************************************************
* missing features
************************************************************************
- explicit blocks with missing end macro should be implicitely closed
at the end of the enclosing block, e.g. .Bl It (El) Sh
reminded by stsp@ in net/pptp pptp.8 Fri, 23 Apr 2010 20:32:39 +0200
- fix bad block nesting involving multiple identical explicit blocks
see the OpenBSD mdoc_macro.c 1.47 commit message
- .Bl -column .Xo support is missing
ultimate goal:
restore .Xr and .Dv to
lib/libc/compat-43/sigvec.3
lib/libc/gen/signal.3
lib/libc/sys/sigaction.2
- edge case: decide how to deal with blk_full bad nesting, e.g.
.Sh .Nm .Bk .Nm .Ek .Sh found by jmc@ in ssh-keygen(1)
from jmc@ Wed, 14 Jul 2010 18:10:32 +0100
- auto-Bk in the SYNOPSIS
patch from kristaps@ Fri, 16 Jul 2010 14:51:24 +0200
to be revisited after OpenBSD 4.8 tree unlock
- implement \\
in plain text, identical to \e
as a macro argument, identical to \ i.e. escaping the next character
We do not have macro definitions yet; if we implement them,
\\ must behave in a macro def like in a macro argument,
and when using the macro, it must expand yet again.
- look at bsd.lv tbl(1)
from kristaps@ Fri, 11 Sep 2009 17:10:53 +0200
also look at the mail from Thomas Klausner wiz at NetBSD
on Wed, 2 Jun 2010 11:01:29 +0200
joerg@ has patches for this somewhere...
- look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
These are a weird mixture of man(7) and custom autogenerated low-level
roff stuff. Figure out to what extent we can cope.
noted by stsp@ Sat, 24 Apr 2010 09:17:55 +0200
reminded by nicm@ Mon, 3 May 2010 09:52:41 +0100
- implement blank `Bl -column', such as
.Bl -column
.It foo Ta bar
.El
- explicitly disallow nested `Bl -column', which would clobber internal
flags defined for struct mdoc_macro
- inside `.Bl -column' phrases, punctuation is handled like normal
text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
- inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
but should give "ab ."
- set a meaningful default if no `Bl' list type is assigned
- have a blank `It' head for `Bl -tag' not puke
- prohibit `Nm' from having non-text HEAD children
(e.g., NetBSD mDNSShared/dns-sd.1)
(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
- allow `Qq', `Dq', `Sq', `Aq', `Bq' to have 0 arguments
noted by Alex Kozlov 08/06/10 23:05
- Have `Sh', `It', `Ss' and others complain if `Pp' is invoked prior to
close (in the post validation) or prior to open (pre). This noted by
jmc@ a thousand years ago.
************************************************************************
* formatting issues: ugly output
************************************************************************
- 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).
- empty phrases in .Bl column produce too few blanks
try e.g. .Bl -column It Ta Ta
reported by millert Fri, 02 Apr 2010 16:13:46 -0400
- in enclosures, mandoc sometimes fancies a bogus end of sentence
reminded by jmc@ Thu, 23 Sep 2010 18:13:39 +0059
************************************************************************
* formatting issues: gratuitious differences
************************************************************************
- .%T should be quoted, not underlined, when .%J is also present,
to better distinguish the contents of .%T and .%J,
see for example OpenBSD cat(1)
- In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
is just "o\bo".
see for example OpenBSD ksh(1)
- .Sm should *not* produce as a blank line in .Bd -literal
see for example "Brace expansion" in OpenBSD ksh(1)
- The characters "|" and "\*(Ba" should never be bold,
not even in the middle of a word, e.g. ".Cm b\*(Bac" in
"mknod [-m mode] name b|c major minor"
in OpenBSD ksh(1)
- 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).
- .Bd -literal and .Bd -unfilled are *not* identical.
In -literal, tabs are 8 spaces.
In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.
See the CCDF_* display in OpenBSD ccdconfig(8).
- .Nx 1.0a
should be "NetBSD 1.0A", not "NetBSD 1.0a",
see OpenBSD ccdconfig(8).
- In .Bl -tag, if a tag exceeds the right margin and must be continued
on the next line, it must be indented by -width, not width+1;
see "rule block|pass" in OpenBSD ifconfig(8).
- The \& zero-width character counts as output.
That is, when it is alone on a line between two .Pp,
we want three blank lines, not two as in mandoc.
************************************************************************
* performance issues
************************************************************************
Several areas can be cleaned up to make mandoc even faster. These are
- improve hashing mechanism for macros (quite important: performance)
- improve hashing mechanism for characters (not as important)
- the PDF file is HUGE: this can be reduced by using relative offsets
************************************************************************
* structural issues
