1.61 schwarze 24:
1.1 kristaps 25: - explicit blocks with missing end macro should be implicitely closed
26: at the end of the enclosing block, e.g. .Bl It (El) Sh
27: reminded by stsp@ in net/pptp pptp.8 Fri, 23 Apr 2010 20:32:39 +0200
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:
43: - auto-Bk in the SYNOPSIS
44: patch from kristaps@ Fri, 16 Jul 2010 14:51:24 +0200
45: to be revisited after OpenBSD 4.8 tree unlock
46:
1.1 kristaps 47: - implement \\
48: in plain text, identical to \e
49: as a macro argument, identical to \ i.e. escaping the next character
50: We do not have macro definitions yet; if we implement them,
51: \\ must behave in a macro def like in a macro argument,
52: and when using the macro, it must expand yet again.
1.22 schwarze 53:
1.60 schwarze 54: - implement basic non-parametric .de to support e.g. sox(1)
55: reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200
1.67 ! schwarze 56: *** sox(1) still doesn't work, tbl(1) errors need investigation
1.64 schwarze 57:
1.62 schwarze 58: - clean up escape sequence handling, creating three classes:
59: (1) fully implemented, or parsed and ignored without loss of content
60: (2) unimplemented, potentially causing loss of content
61: or serious mangling of formatting (e.g. \n) -> ERROR
62: see textproc/mgdiff(1) for nice examples
63: (3) undefined, just output the character -> perhaps WARNING
1.60 schwarze 64:
65: - port OpenBSD tbl integration bsd.lv, probably cleaning it up
1.1 kristaps 66:
67: - look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
68: These are a weird mixture of man(7) and custom autogenerated low-level
69: roff stuff. Figure out to what extent we can cope.

71: reminded by nicm@ Mon, 3 May 2010 09:52:41 +0100
72:
1.10 kristaps 73: - implement blank `Bl -column', such as
74: .Bl -column
75: .It foo Ta bar
76: .El
1.11 kristaps 77:
78: - explicitly disallow nested `Bl -column', which would clobber internal
79: flags defined for struct mdoc_macro
1.42 schwarze 80:
81: - inside `.Bl -column' phrases, punctuation is handled like normal
82: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
83:
84: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
85: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
86: but should give "ab ."
1.12 kristaps 87:
88: - set a meaningful default if no `Bl' list type is assigned
1.13 kristaps 89:
90: - have a blank `It' head for `Bl -tag' not puke
1.20 kristaps 91:
92: - prohibit `Nm' from having non-text HEAD children
93: (e.g., NetBSD mDNSShared/dns-sd.1)
94: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.57 kristaps 95:
96: - Have `Sh', `It', `Ss' and others complain if `Pp' is invoked prior to
97: close (in the post validation) or prior to open (pre). This noted by
98: jmc@ a thousand years ago.
1.41 kristaps 99:
1.63 schwarze 100: - xloadimage(1) wants .ti (temporary indent), rep by naddy@
101:
102: - bashbug(1) complains "line scope broken" after
103: .SM
104: .B something
105: should either just work or be a warning

109: * formatting issues: ugly output
110: ************************************************************************
1.33 schwarze 111:
1.67 ! schwarze 112: - double quotes inside double quotes are escaped by doubling them
! 113: implement this in man(7) and mdoc(7)
! 114: reminded by millert@ Thu, 09 Dec 2010 17:29:52 -0500
! 115:
1.28 schwarze 116: - perl(1) SYNOPSIS looks bad; reported by deraadt@
1.29 kristaps 117: 1) man(7) seems to need SYNOPSIS .Nm blocks, too
1.1 kristaps 118:
1.39 schwarze 119: - In .Bl -column,
120: .It Em Authentication<tab>Key Length
121: ought to render "Key Length" with emphasis, too,
122: see OpenBSD iked.conf(5).
123:
1.1 kristaps 124: - empty phrases in .Bl column produce too few blanks
125: try e.g. .Bl -column It Ta Ta

1.48 schwarze 127:
128: - in enclosures, mandoc sometimes fancies a bogus end of sentence
129: reminded by jmc@ Thu, 23 Sep 2010 18:13:39 +0059

1.1 kristaps 131: ************************************************************************
132: * formatting issues: gratuitious differences
133: ************************************************************************
1.65 kristaps 134:
135: - .Rv (and probably .Ex) print different text if an `Nm' has been named
136: or not (run a manual without `Nm blah' to see this). I'm not sure
137: that this exists in the wild, but it's still an error.
1.1 kristaps 138:
1.38 schwarze 139: - .%T should be quoted, not underlined, when .%J is also present,
140: to better distinguish the contents of .%T and .%J,
141: see for example OpenBSD cat(1)
142:
143: - In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
144: is just "o\bo".
145: see for example OpenBSD ksh(1)
146:
147: - The characters "|" and "\*(Ba" should never be bold,
148: not even in the middle of a word, e.g. ".Cm b\*(Bac" in
149: "mknod [-m mode] name b|c major minor"
150: in OpenBSD ksh(1)
151:
152: - A bogus .Pp between two .It must not produce a double blank line,
1.39 schwarze 153: see between -R and -r in OpenBSD rm(1), before "update" in mount(8),
154: or in DIAGNOSTICS in init(8).
155:
156: - .Bd -literal and .Bd -unfilled are *not* identical.
157: In -literal, tabs are 8 spaces.
158: In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.
159: See the CCDF_* display in OpenBSD ccdconfig(8).
160:
161: - .Nx 1.0a
162: should be "NetBSD 1.0A", not "NetBSD 1.0a",
163: see OpenBSD ccdconfig(8).
164:
165: - In .Bl -tag, if a tag exceeds the right margin and must be continued
166: on the next line, it must be indented by -width, not width+1;
167: see "rule block|pass" in OpenBSD ifconfig(8).
1.56 schwarze 168:
169: - The \& zero-width character counts as output.
170: That is, when it is alone on a line between two .Pp,
171: we want three blank lines, not two as in mandoc.
1.63 schwarze 172:
173: - When .Fn arguments exceed one output line, all but the first
174: should be indented, see e.g. rpc(3);
175: reported by jmc@ on discuss@ Fri, 29 Oct 2010 13:48:33 +0100
176:
177: - It seems that .TP does not want TWOSPACE after the tag;
178: see bashbug(1); reported by naddy@
1.64 schwarze 179:
180: - Header lines of excessive length:
181: Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c
182: and document it in mdoc(7) and man(7) COMPATIBILITY
183: found while talking to Chris Bennett

1.9 kristaps 185: ************************************************************************
186: * performance issues
187: ************************************************************************
188:
189: Several areas can be cleaned up to make mandoc even faster. These are
190:
191: - improve hashing mechanism for macros (quite important: performance)
192:
193: - improve hashing mechanism for characters (not as important)
1.23 kristaps 194:
1.37 kristaps 195: - the PDF file is HUGE: this can be reduced by using relative offsets
