- .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 \} |

| as a macro argument, identical to \ i.e. escaping the next character |
* when parsing roff(7) and man(7) macro arguments |
| We do not have macro definitions yet; if we implement them, |
It does not yet work in mdoc(7) macro arguments |
| \\ must behave in a macro def like in a macro argument, |
because libmdoc does not yet use mandoc_getarg(). |
| and when using the macro, it must expand yet again. |
Also check what happens in plain text, it must be identical to \e. |

the left and right margin. In groff, it is implemented in terms |
| |
of .ad b, which we don't have either. Found in cksum(1). |
| |
|
| |
- 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) |

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

| |
--- 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 |
| |
|
| |
--- missing misc features ---------------------------------------------- |
| |
|
| |
- 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 |
| |
|
| |
- The \t escape sequence is the same as a literal tab, see for example |
| |
the ASCII table in hexdump(1) where |
| |
.Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo |
| |
.It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq |
| |
produces |
| |
000 nul 001 soh 002 stx 003 etx 004 eot 005 enq |
| |

| - nroff inserts a space before :, mandoc doesn't: |
- .%T can have trailing punctuation. Currently, it puts the trailing |
| .Dl expr "/$a" Li : '.*/\e(.*\e)' |
punctuation into a trailing MDOC_TEXT element inside its own scope. |
| |
That element should rather be outside its scope, such that the |
| |
punctuation does not get underlines. This is not trivial to |
| |
implement because .%T then needs some features of in_line_eoln() - |
| |
slurp all arguments into one single text element - and one feature |
| |
of in_line() - put trailing punctuation out of scope. |
| |
Found in mount_nfs(8) and exports(5), search for "Appendix". |
| |
|
| |
- in enclosures, mandoc sometimes fancies a bogus end of sentence |

| - FIXED OpenBSD mdoc.c 1.52 schwarze 16.5.10 |
- .Rv (and probably .Ex) print different text if an `Nm' has been named |
| lines containing blank characters, and nothing else, |
or not (run a manual without `Nm blah' to see this). I'm not sure |
| in literal context (.Bd -literal): |
that this exists in the wild, but it's still an error. |
| groff outputs just blank lines "\n" |
|
| mandoc outputs blanks to the left margin, |
|
| then the number of balnks minus one |
|
| NEEDS MERGING TO bsd.lv |
|
| |
|
| |
- 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), 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). |
| |
|
| |
- If the first line after .It is .D1, do not assert a blank line |
| |
in between, see for example tmux(1). |
| |
reported by nicm@ 13 Jan 2011 00:18:57 +0000 |
| |
|
| |
- .Nx 1.0a |
| |
should be "NetBSD 1.0A", not "NetBSD 1.0a", |
| |
see OpenBSD ccdconfig(8). |
| |
|
| |
- The space character joining .Dx .Fx .Nx .Ox (are these all?) to its |
| |
argument is non-breaking. See the cdio(1) HISTORY and many others. |
| |
|
| |
- 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). |
| |
|
| |
- When the -width string contains macros, the macros must be rendered |
| |
before measuring the width, for example |
| |
.Bl -tag -width ".Dv message" |
| |
in magic(5), located in src/usr.bin/file, is the same |
| |
as -width 7n, not -width 11n. |
| |
|
| |
- 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 |
| |
|
| |
- .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 |
| |
.Op Ar line |
| |
.Cm a Ns Op Cm ppend Ns |
| |
.Op Cm !\& |
| |
.Xc |
| |
The input text is appended after the specified line. |

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

| |
|
| |
- In man(7), the sequence |
| |
.HP |
| |
one line of regular text |
| |
.SH |
| |
should not produce two blank lines before the .SH, |
| |
see for example named-checkconf(8). |
| |
|
| |
- In man(7), the sequence |
| |
regular text |
| |
.RS |
| |
.IP |
| |
should have a blank line between the text and the beginning of the |
| |
indented paragraph, see for example sudo(1). |
| |
|
| |
- 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, |
