! 18: ************************************************************************
! 19:
! 20: - in literal mode, the man(7) -Tascii formatter
! 21: breaks the line between macro arguments,
! 22: e.g. ".B #include <libintl.h>" in gettext(3)

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

1.1 kristaps 104: ************************************************************************
105: * formatting issues: ugly output
106: ************************************************************************
1.33 schwarze 107:
1.67 schwarze 108: - double quotes inside double quotes are escaped by doubling them
1.74 ! schwarze 109: implement this in mdoc(7), too
! 110: so far, we only have it in roff(7) and man(7)
1.67 schwarze 111: reminded by millert@ Thu, 09 Dec 2010 17:29:52 -0500
112:
1.28 schwarze 113: - perl(1) SYNOPSIS looks bad; reported by deraadt@
1.29 kristaps 114: 1) man(7) seems to need SYNOPSIS .Nm blocks, too
1.1 kristaps 115:
1.39 schwarze 116: - In .Bl -column,
117: .It Em Authentication<tab>Key Length
118: ought to render "Key Length" with emphasis, too,
119: see OpenBSD iked.conf(5).
120:
1.1 kristaps 121: - empty phrases in .Bl column produce too few blanks
122: try e.g. .Bl -column It Ta Ta
123: reported by millert Fri, 02 Apr 2010 16:13:46 -0400
1.48 schwarze 124:
125: - in enclosures, mandoc sometimes fancies a bogus end of sentence

1.35 kristaps 127:
1.1 kristaps 128: ************************************************************************
129: * formatting issues: gratuitious differences
130: ************************************************************************
1.65 kristaps 131:
132: - .Rv (and probably .Ex) print different text if an `Nm' has been named
133: or not (run a manual without `Nm blah' to see this). I'm not sure
134: that this exists in the wild, but it's still an error.
1.38 schwarze 135:
136: - In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
137: is just "o\bo".
138: see for example OpenBSD ksh(1)
139:
140: - The characters "|" and "\*(Ba" should never be bold,
141: not even in the middle of a word, e.g. ".Cm b\*(Bac" in
142: "mknod [-m mode] name b|c major minor"
143: in OpenBSD ksh(1)
144:
145: - A bogus .Pp between two .It must not produce a double blank line,
1.39 schwarze 146: see between -R and -r in OpenBSD rm(1), before "update" in mount(8),
147: or in DIAGNOSTICS in init(8).
1.68 kristaps 148: Also have `It' complain if `Pp' is invoked at certain times (not
149: -compact?).
1.39 schwarze 150:
151: - .Nx 1.0a
152: should be "NetBSD 1.0A", not "NetBSD 1.0a",
153: see OpenBSD ccdconfig(8).
154:
155: - In .Bl -tag, if a tag exceeds the right margin and must be continued
156: on the next line, it must be indented by -width, not width+1;
157: see "rule block|pass" in OpenBSD ifconfig(8).
1.56 schwarze 158:
159: - The \& zero-width character counts as output.
160: That is, when it is alone on a line between two .Pp,
161: we want three blank lines, not two as in mandoc.
1.63 schwarze 162:
163: - When .Fn arguments exceed one output line, all but the first
164: should be indented, see e.g. rpc(3);
165: reported by jmc@ on discuss@ Fri, 29 Oct 2010 13:48:33 +0100
1.64 schwarze 166:
167: - Header lines of excessive length:
168: Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c
169: and document it in mdoc(7) and man(7) COMPATIBILITY
170: found while talking to Chris Bennett

1.9 kristaps 172: ************************************************************************
173: * performance issues
174: ************************************************************************
175:
176: Several areas can be cleaned up to make mandoc even faster. These are
177:
178: - improve hashing mechanism for macros (quite important: performance)
179:
180: - improve hashing mechanism for characters (not as important)
1.23 kristaps 181:
1.37 kristaps 182: - the PDF file is HUGE: this can be reduced by using relative offsets
183:
1.23 kristaps 184: ************************************************************************
185: * structural issues
186: ************************************************************************
1.67 schwarze 187:
188: - Find better ways to prevent endless loops
189: in roff(7) macro and string expansion.
