1.184 schwarze 6: Many issues are annotated for difficulty as follows:
7:
8: - loc = locality of the issue
9: * single file issue, affects file only, or very few
10: ** single module issue, affects several files of one module
11: *** cross-module issue, significantly impacts multiple modules
12: and may require substantial changes to internal interfaces
13: - exist = difficulty of the existing code in this area
14: * affected code is straightforward and easy to read and change
15: ** affected code is somewhat complex, but once you understand
16: the design, not particularly difficult to understand
17: *** affected code uses a special, exceptionally tricky design
18: - algo = difficulty of the new algorithm to be written
19: * the required logic and code is straightforward
20: ** the required logic is somewhat complex and needs a careful design
21: *** the required logic is exceptionally tricky,
22: maybe an approach to solve that is not even known yet
23: - size = the amount of code to be written or changed
24: * a small number of lines (at most 100, usually much less)
25: ** a considerable amount of code (several dozen to a few hundred)
26: *** a large amount of code (many hundreds, maybe thousands)
27: - imp = importance of the issue
28: * mostly for completeness
29: ** would be nice to have
30: *** issue causes considerable inconvenience
31:
32: Obviously, as the issues have not been solved yet, these annotations
33: are mere guesses, and some may be wrong.

75: - \\ in high-level macro arguments
76: Currently, \\ is expanded in two situations:
77: 1) macro and string definition (roff.c setstrn())
78: 2) macro argument parsing (mandoc.c mandoc_getarg())
79: For user defined macros, the second happens in time because of ROFF_REPARSE.
80: But for standard high-level macros, it only happens after entering the
81: high level parsers, which is too late because the code doesn't get
82: back to roff.c roff_res() from that point. Because this requires
83: distinguishing requests, user-defined macros and standard macros
84: on the roff_res() level, it is hard to solve without the parser reorg.

1.28 schwarze 108:
1.174 schwarze 109: - .Bd -centered implies -filled, not -unfilled, which is not
110: easy to implement; it requires code similar to .ce, which
111: we don't have either.
112: Besides, groff has bug causing text right *before* .Bd -centered
113: to be centered as well.
1.184 schwarze 114: loc *** exist *** algo ** size ** imp ** (parser reorg would help)
1.174 schwarze 115:
1.82 schwarze 116: - .Bd -filled should not be the same as .Bd -ragged, but align both
117: the left and right margin. In groff, it is implemented in terms
118: of .ad b, which we don't have either. Found in cksum(1).

1.184 schwarze 140: loc * exist *** algo ** size * imp **
1.42 schwarze 141:
142: - inside `.Bl -column' phrases, punctuation is handled like normal
143: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
144:
145: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
146: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
147: but should give "ab ."
1.12 kristaps 148:
1.20 kristaps 149: - prohibit `Nm' from having non-text HEAD children
150: (e.g., NetBSD mDNSShared/dns-sd.1)
151: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.109 schwarze 152:
1.174 schwarze 153: - support translated section names
154: e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
155: that one uses NOMBRE because it is spanish...
156: deraadt tends to think that section-dependent macro behaviour
157: is a bad idea in the first place, so this may be irrelevant
1.184 schwarze 158: loc ** exist ** algo ** size * imp **
1.174 schwarze 159:
1.109 schwarze 160: - When there is free text in the SYNOPSIS and that free text contains
161: the .Nm macro, groff somehow understands to treat the .Nm as an in-line
162: macro, while mandoc treats it as a block macro and breaks the line.
163: No idea how the logic for distinguishing in-line and block instances
164: should be, needs investigation.

181: These macros were used by the GNU grep(1) man page.
1.258 schwarze 182: The groff_www(7) manual page itself uses them, too.
1.252 schwarze 183: We should probably *not* add them to mandoc.
