1.70 kristaps 23:
24: - pod2man expects `tr' to be implemented for \*(-- to work
1.61 schwarze 25:
1.75 schwarze 26: - implement `rm' - it is easy to do and used in the pod2man preamble
27: reminded by brad@ Sun, Jan 09, 2011 at 09:45:58PM -0500
28:
1.18 schwarze 29: - fix bad block nesting involving multiple identical explicit blocks
30: see the OpenBSD mdoc_macro.c 1.47 commit message
31:
1.1 kristaps 32: - .Bl -column .Xo support is missing
33: ultimate goal:
34: restore .Xr and .Dv to
35: lib/libc/compat-43/sigvec.3
36: lib/libc/gen/signal.3
37: lib/libc/sys/sigaction.2
38:
1.28 schwarze 39: - edge case: decide how to deal with blk_full bad nesting, e.g.
40: .Sh .Nm .Bk .Nm .Ek .Sh found by jmc@ in ssh-keygen(1)
41: from jmc@ Wed, 14 Jul 2010 18:10:32 +0100
42:
1.74 schwarze 43: - \\ is now implemented correctly
44: * when defining strings and macros using .ds and .de
45: * when parsing roff(7) and man(7) macro arguments
46: It does not yet work in mdoc(7) macro arguments
47: because libmdoc does not yet use mandoc_getarg().
48: Also check what happens in plain text, it must be identical to \e.
1.22 schwarze 49:
1.60 schwarze 50: - implement basic non-parametric .de to support e.g. sox(1)
51: reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200
1.67 schwarze 52: *** sox(1) still doesn't work, tbl(1) errors need investigation
1.64 schwarze 53:
1.62 schwarze 54: - clean up escape sequence handling, creating three classes:
55: (1) fully implemented, or parsed and ignored without loss of content
56: (2) unimplemented, potentially causing loss of content
57: or serious mangling of formatting (e.g. \n) -> ERROR
58: see textproc/mgdiff(1) for nice examples
59: (3) undefined, just output the character -> perhaps WARNING
1.1 kristaps 60:
61: - look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
62: These are a weird mixture of man(7) and custom autogenerated low-level
63: roff stuff. Figure out to what extent we can cope.
64: noted by stsp@ Sat, 24 Apr 2010 09:17:55 +0200
65: reminded by nicm@ Mon, 3 May 2010 09:52:41 +0100
66:
1.10 kristaps 67: - implement blank `Bl -column', such as
68: .Bl -column
69: .It foo Ta bar
70: .El
1.11 kristaps 71:
72: - explicitly disallow nested `Bl -column', which would clobber internal
73: flags defined for struct mdoc_macro
1.42 schwarze 74:
75: - inside `.Bl -column' phrases, punctuation is handled like normal
76: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
77:
78: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
79: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
80: but should give "ab ."
1.12 kristaps 81:
82: - set a meaningful default if no `Bl' list type is assigned
1.13 kristaps 83:
84: - have a blank `It' head for `Bl -tag' not puke
1.20 kristaps 85:
86: - prohibit `Nm' from having non-text HEAD children
87: (e.g., NetBSD mDNSShared/dns-sd.1)
88: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.57 kristaps 89:
1.63 schwarze 90: - xloadimage(1) wants .ti (temporary indent), rep by naddy@
91:
92: - bashbug(1) complains "line scope broken" after
93: .SM
94: .B something
95: should either just work or be a warning
96: reported by naddy@
1.71 schwarze 97:
98: - check compatibility with Plan9:
99: http://swtch.com/usr/local/plan9/tmac/tmac.an
100: http://swtch.com/plan9port/man/man7/man.html

1.1 kristaps 103: ************************************************************************
104: * formatting issues: ugly output
105: ************************************************************************
1.33 schwarze 106:
1.67 schwarze 107: - double quotes inside double quotes are escaped by doubling them
1.74 schwarze 108: implement this in mdoc(7), too
109: so far, we only have it in roff(7) and man(7)
1.67 schwarze 110: reminded by millert@ Thu, 09 Dec 2010 17:29:52 -0500
111:
1.28 schwarze 112: - perl(1) SYNOPSIS looks bad; reported by deraadt@
1.29 kristaps 113: 1) man(7) seems to need SYNOPSIS .Nm blocks, too
1.1 kristaps 114:
1.39 schwarze 115: - In .Bl -column,
116: .It Em Authentication<tab>Key Length
117: ought to render "Key Length" with emphasis, too,
118: see OpenBSD iked.conf(5).
119:
1.1 kristaps 120: - empty phrases in .Bl column produce too few blanks
121: try e.g. .Bl -column It Ta Ta
122: reported by millert Fri, 02 Apr 2010 16:13:46 -0400
1.48 schwarze 123:
124: - in enclosures, mandoc sometimes fancies a bogus end of sentence
125: reminded by jmc@ Thu, 23 Sep 2010 18:13:39 +0059
1.35 kristaps 126:
1.1 kristaps 127: ************************************************************************
128: * formatting issues: gratuitious differences
129: ************************************************************************
1.65 kristaps 130:
131: - .Rv (and probably .Ex) print different text if an `Nm' has been named
132: or not (run a manual without `Nm blah' to see this). I'm not sure
133: that this exists in the wild, but it's still an error.
1.38 schwarze 134:
135: - In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
136: is just "o\bo".
137: see for example OpenBSD ksh(1)
138:
139: - The characters "|" and "\*(Ba" should never be bold,
140: not even in the middle of a word, e.g. ".Cm b\*(Bac" in
141: "mknod [-m mode] name b|c major minor"
142: in OpenBSD ksh(1)
143:
144: - A bogus .Pp between two .It must not produce a double blank line,
1.39 schwarze 145: see between -R and -r in OpenBSD rm(1), before "update" in mount(8),
146: or in DIAGNOSTICS in init(8).
1.68 kristaps 147: Also have `It' complain if `Pp' is invoked at certain times (not
148: -compact?).
1.39 schwarze 149:
150: - .Nx 1.0a
151: should be "NetBSD 1.0A", not "NetBSD 1.0a",
152: see OpenBSD ccdconfig(8).
153:
154: - In .Bl -tag, if a tag exceeds the right margin and must be continued
155: on the next line, it must be indented by -width, not width+1;
156: see "rule block|pass" in OpenBSD ifconfig(8).
1.56 schwarze 157:
158: - The \& zero-width character counts as output.
159: That is, when it is alone on a line between two .Pp,
160: we want three blank lines, not two as in mandoc.
1.63 schwarze 161:
162: - When .Fn arguments exceed one output line, all but the first
163: should be indented, see e.g. rpc(3);
164: reported by jmc@ on discuss@ Fri, 29 Oct 2010 13:48:33 +0100
1.64 schwarze 165:
166: - Header lines of excessive length:
167: Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c
168: and document it in mdoc(7) and man(7) COMPATIBILITY
169: found while talking to Chris Bennett
1.75 schwarze 170:
171: ************************************************************************
172: * error reporting issues
173: ************************************************************************
174:
175: - downgrade "ERROR: macro requires body argument(s)" to WARNING
176: for the typical man(7) cases, it keeps confusing people

1.1 kristaps 178:
1.9 kristaps 179: ************************************************************************
180: * performance issues
181: ************************************************************************
182:
183: Several areas can be cleaned up to make mandoc even faster. These are
184:
185: - improve hashing mechanism for macros (quite important: performance)
186:
187: - improve hashing mechanism for characters (not as important)
1.23 kristaps 188:
1.37 kristaps 189: - the PDF file is HUGE: this can be reduced by using relative offsets
190:
1.23 kristaps 191: ************************************************************************
192: * structural issues
193: ************************************************************************
1.67 schwarze 194:
195: - Find better ways to prevent endless loops
196: in roff(7) macro and string expansion.
