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.

1.42 schwarze 105:
106: - inside `.Bl -column' phrases, punctuation is handled like normal
107: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
108:
109: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
110: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
111: but should give "ab ."
1.12 kristaps 112:
1.20 kristaps 113: - prohibit `Nm' from having non-text HEAD children
114: (e.g., NetBSD mDNSShared/dns-sd.1)
115: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.109 schwarze 116:
1.174 schwarze 117: - support translated section names
118: e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
119: that one uses NOMBRE because it is spanish...

1.109 schwarze 124: - When there is free text in the SYNOPSIS and that free text contains
125: the .Nm macro, groff somehow understands to treat the .Nm as an in-line
126: macro, while mandoc treats it as a block macro and breaks the line.
127: No idea how the logic for distinguishing in-line and block instances
128: should be, needs investigation.

1.209 schwarze 163:
164: - In a matrix, break the output line after each matrix line.
1.287 ! schwarze 165: Found in the discussion at CDBUG 2015. Suggested by Avi Weinstock.
! 166: This may not be the ideal solution after all: eqn(7) matrices
! 167: are lists of columns, so Avi's proposal would show each *column*
! 168: on its own *line*, which is likely to cause confusion.
! 169: A better solution, but much harder to implement, would be to
! 170: actually show the coordinates of column vectors on different

186: - GNU eqn converts some operators to special characters, for example,
187: input HYPHEN-MINUS becomes output \(mi, unless it is part of a
188: quoted word. mandoc(1) only does this when the operator is
189: surrounded by blanks, not when it is part of an unquoted word.
190: Also, check whether there are more such cases (e.g., +?).
