************************************************************************ * Official mandoc TODO. * $Id$ ************************************************************************ ************************************************************************ * parser bugs ************************************************************************ - the roff parser doesn't tolerate additional characters between a macro and the \} terminating a conditional block, e.g. .if n \{ .br \} reported by ulrich spoerlein Tue, 19 Oct 2010 20:39:50 +0200 ************************************************************************ * formatter bugs ************************************************************************ ************************************************************************ * missing features ************************************************************************ - pod2man expects `tr' to be implemented for \*(-- to work - implement `rm' - it is easy to do and used in the pod2man preamble reminded by brad@ Sun, Jan 09, 2011 at 09:45:58PM -0500 - 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 - \\ is now implemented correctly * when defining strings and macros using .ds and .de * when parsing roff(7) and man(7) macro arguments It does not yet work in mdoc(7) macro arguments because libmdoc does not yet use mandoc_getarg(). Also check what happens in plain text, it must be identical to \e. - 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 - clean up escape sequence handling, creating three classes: (1) fully implemented, or parsed and ignored without loss of content (2) unimplemented, potentially causing loss of content or serious mangling of formatting (e.g. \n) -> ERROR see textproc/mgdiff(1) for nice examples (3) undefined, just output the character -> perhaps WARNING - 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) - xloadimage(1) wants .ti (temporary indent), rep by naddy@ - bashbug(1) complains "line scope broken" after .SM .B something should either just work or be a warning reported by naddy@ - check compatibility with Plan9: http://swtch.com/usr/local/plan9/tmac/tmac.an http://swtch.com/plan9port/man/man7/man.html "Anthony J. Bentley" 28 Dec 2010 21:58:40 -0700 ************************************************************************ * formatting issues: ugly output ************************************************************************ - double quotes inside double quotes are escaped by doubling them implement this in mdoc(7), too 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 AuthenticationKey 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 ************************************************************************ - .Rv (and probably .Ex) print different text if an `Nm' has been named or not (run a manual without `Nm blah' to see this). I'm not sure that this exists in the wild, but it's still an error. - In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet is just "o\bo". see for example 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). Also have `It' complain if `Pp' is invoked at certain times (not -compact?). - .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. - 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 - 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 ************************************************************************ * error reporting issues ************************************************************************ ************************************************************************ * 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 ************************************************************************ - Find better ways to prevent endless loops in roff(7) macro and string expansion.
