1.18 schwarze 14: - fix bad block nesting involving multiple identical explicit blocks
15: see the OpenBSD mdoc_macro.c 1.47 commit message
16:
1.1 kristaps 17: - .Bl -column .Xo support is missing
18: ultimate goal:
19: restore .Xr and .Dv to
20: lib/libc/compat-43/sigvec.3
21: lib/libc/gen/signal.3
22: lib/libc/sys/sigaction.2
23:
1.28 schwarze 24: - edge case: decide how to deal with blk_full bad nesting, e.g.
25: .Sh .Nm .Bk .Nm .Ek .Sh found by jmc@ in ssh-keygen(1)
26: from jmc@ Wed, 14 Jul 2010 18:10:32 +0100
27:
28: - auto-Bk in the SYNOPSIS
29: patch from kristaps@ Fri, 16 Jul 2010 14:51:24 +0200
30: to be revisited after OpenBSD 4.8 tree unlock
31:
1.1 kristaps 32: - implement \\
33: in plain text, identical to \e
34: as a macro argument, identical to \ i.e. escaping the next character
35: We do not have macro definitions yet; if we implement them,
36: \\ must behave in a macro def like in a macro argument,
37: and when using the macro, it must expand yet again.
1.22 schwarze 38:
1.1 kristaps 39: - look at bsd.lv tbl(1)
40: from kristaps@ Fri, 11 Sep 2009 17:10:53 +0200
1.17 schwarze 41: also look at the mail from Thomas Klausner wiz at NetBSD

1.35 kristaps 43: joerg@ has patches for this somewhere...
1.1 kristaps 44:
45: - look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
46: These are a weird mixture of man(7) and custom autogenerated low-level
47: roff stuff. Figure out to what extent we can cope.

50:
1.10 kristaps 51: - implement blank `Bl -column', such as
52: .Bl -column
53: .It foo Ta bar
54: .El
1.11 kristaps 55:
56: - explicitly disallow nested `Bl -column', which would clobber internal
57: flags defined for struct mdoc_macro
1.42 ! schwarze 58:
! 59: - inside `.Bl -column' phrases, punctuation is handled like normal
! 60: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
! 61:
! 62: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
! 63: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
! 64: but should give "ab ."
1.12 kristaps 65:
66: - set a meaningful default if no `Bl' list type is assigned
1.13 kristaps 67:
68: - have a blank `It' head for `Bl -tag' not puke
1.20 kristaps 69:
70: - prohibit `Nm' from having non-text HEAD children
71: (e.g., NetBSD mDNSShared/dns-sd.1)
72: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.36 kristaps 73:
74: - allow `Qq', `Dq', `Sq', `Aq', `Bq' to have 0 arguments
75: noted by Alex Kozlov 08/06/10 23:05
1.41 kristaps 76:
77: - 'br\} doesn't correctly close scope.

1.33 schwarze 83:
1.28 schwarze 84: - perl(1) SYNOPSIS looks bad; reported by deraadt@
1.29 kristaps 85: 1) man(7) seems to need SYNOPSIS .Nm blocks, too
1.1 kristaps 86:
1.39 schwarze 87: - In .Bl -column,
88: .It Em Authentication<tab>Key Length
89: ought to render "Key Length" with emphasis, too,
90: see OpenBSD iked.conf(5).
91:
1.1 kristaps 92: - empty phrases in .Bl column produce too few blanks
93: try e.g. .Bl -column It Ta Ta

1.35 kristaps 95:
96: - %A doesn't put an "and" before the final author name.

98: ************************************************************************
99: * formatting issues: gratuitious differences
100: ************************************************************************
101:
1.38 schwarze 102: - .%T should be quoted, not underlined, when .%J is also present,
103: to better distinguish the contents of .%T and .%J,
104: see for example OpenBSD cat(1)
105:
106: - .It ${name Ns [ selector ] Ns }
107: should be "${name[selector]}" not "${name [selector]}"
108: This is parsed as
109: text("${name") text("[") Ns() text(selector)...
110: Opening punctuation should not fall out of .Ns.
111: see for example OpenBSD csh(1)
112:
113: - .%A should append the last author with " and " (if there are two)
114: or ", and " (if there are more), not ", "
115: see for example OpenBSD csh(1)
116:
117: - In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
118: is just "o\bo".
119: see for example OpenBSD ksh(1)
120:
121: - .No text No ) is "text )", not "text)"
122: see the terrible example
123: case word in [[(] pattern [| pattern] ... ) list ;; ] ... esac
124: in OpenBSD ksh(1)
125:
126: - .Sm should *not* produce as a blank line in .Bd -literal
127: see for example "Brace expansion" in OpenBSD ksh(1)
128:
129: - The characters "|" and "\*(Ba" should never be bold,
130: not even in the middle of a word, e.g. ".Cm b\*(Bac" in
131: "mknod [-m mode] name b|c major minor"
132: in OpenBSD ksh(1)
133:
134: - A bogus .Pp between two .It must not produce a double blank line,
1.39 schwarze 135: see between -R and -r in OpenBSD rm(1), before "update" in mount(8),
136: or in DIAGNOSTICS in init(8).
137:
138: - .Bd -literal and .Bd -unfilled are *not* identical.
139: In -literal, tabs are 8 spaces.
140: In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.
141: See the CCDF_* display in OpenBSD ccdconfig(8).
142:
143: - In .Bd -unfilled, .Pp should produce one blank line, not two;
144: see the ccd.conf display in OpenBSD ccdconfig(8).
145:
146: - .Nx 1.0a
147: should be "NetBSD 1.0A", not "NetBSD 1.0a",
148: see OpenBSD ccdconfig(8).
149:
150: - In .Bl -tag, if a tag exceeds the right margin and must be continued
151: on the next line, it must be indented by -width, not width+1;
152: see "rule block|pass" in OpenBSD ifconfig(8).
153:
154: - When .%T is used outside an .Rs context and with a trailing comma,
155: there is no point in rendering two commata,
156: see the first paragraph of the DESCRIPTION in OpenBSD mount_nfs(8).
157:
158: - When .%T is used outside an .Rs context and without a trailing comma,
159: no comma should be rendered at all,
160: see the first paragraph of the DESCRIPTION in OpenBSD exports(5).
161:
162: - Bogus .Pp before .Bl should not cause a double blank line,
163: see "The route utility provides the following simple commands:"
164: in OpenBSD route(8).

1.9 kristaps 166: ************************************************************************
167: * performance issues
168: ************************************************************************
169:
170: Several areas can be cleaned up to make mandoc even faster. These are
171:
172: - improve hashing mechanism for macros (quite important: performance)
173:
174: - improve hashing mechanism for characters (not as important)
1.23 kristaps 175:
1.37 kristaps 176: - the PDF file is HUGE: this can be reduced by using relative offsets
177:
1.23 kristaps 178: ************************************************************************
179: * structural issues
180: ************************************************************************
1.33 schwarze 181:
182: - rendering frontend code can calculate widths only for plain strings,
183: not for strings containing escape sequences. For example, this
184: hinders calculation of the indent required for .Nm \&[ in text(1).
185: comments from kristaps@ Wed, 21 Jul 2010 23:26:08 +0200
1.38 schwarze 186:
187: - another example of the same problem:
188: .Bl -tag -width "\eD{format}XX" -compact
189: in OpenBSD ksh(1) gives the wrong width
190: because "\e" is one character in groff, two in mandoc
191:
1.40 kristaps 192: - Now that `ds' is minimally supported, we can get rid of some
193: predefined strings. \*(C+ has already been thrown out. Track these
194: down and whack them. Look in e.g. gcc.1 for the top-level `ds'
195: invocations. These are reproduced across most crappy GNU manuals.
