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.

1.28 schwarze 122:
1.174 schwarze 123: - .Bd -centered implies -filled, not -unfilled, which is not
124: easy to implement; it requires code similar to .ce, which
125: we don't have either.
126: Besides, groff has bug causing text right *before* .Bd -centered

1.184 schwarze 128: loc *** exist *** algo ** size ** imp ** (parser reorg would help)
1.174 schwarze 129:
1.82 schwarze 130: - .Bd -filled should not be the same as .Bd -ragged, but align both
131: the left and right margin. In groff, it is implemented in terms
132: of .ad b, which we don't have either. Found in cksum(1).

1.184 schwarze 154: loc * exist *** algo ** size * imp **
1.42 schwarze 155:
156: - inside `.Bl -column' phrases, punctuation is handled like normal
157: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
158:
159: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
160: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
161: but should give "ab ."
1.12 kristaps 162:
1.174 schwarze 163: - check whether it is correct that `D1' uses INDENT+1;

1.174 schwarze 166:
1.20 kristaps 167: - prohibit `Nm' from having non-text HEAD children
168: (e.g., NetBSD mDNSShared/dns-sd.1)
169: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.109 schwarze 170:
1.174 schwarze 171: - support translated section names
172: e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
173: that one uses NOMBRE because it is spanish...
174: deraadt tends to think that section-dependent macro behaviour
175: is a bad idea in the first place, so this may be irrelevant
1.184 schwarze 176: loc ** exist ** algo ** size * imp **
1.174 schwarze 177:
1.109 schwarze 178: - When there is free text in the SYNOPSIS and that free text contains
179: the .Nm macro, groff somehow understands to treat the .Nm as an in-line
180: macro, while mandoc treats it as a block macro and breaks the line.
181: No idea how the logic for distinguishing in-line and block instances
182: should be, needs investigation.
