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.

1.291 ! schwarze 64:
! 65: - .als only works for macros in mandoc, not for user-defined strings.
! 66: Also, the "val" field in struct roffkv would have to be replaced
! 67: with a pointer to a reference-counted wrapper, and an alias
! 68: would have to point to the same wrapper as the original.
! 69: .als to undefined does nothing; the alias is not created.
! 70: .rm'ing the original leaves the alias to point to the old value.
! 71: .de .als .de changes both, but

1.42 schwarze 126:
127: - inside `.Bl -column' phrases, punctuation is handled like normal
128: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
129:
130: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
131: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."

1.12 kristaps 133:
1.20 kristaps 134: - prohibit `Nm' from having non-text HEAD children
135: (e.g., NetBSD mDNSShared/dns-sd.1)
136: (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
1.109 schwarze 137:
1.174 schwarze 138: - support translated section names
139: e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
140: that one uses NOMBRE because it is spanish...
141: deraadt tends to think that section-dependent macro behaviour

1.174 schwarze 144:
1.109 schwarze 145: - When there is free text in the SYNOPSIS and that free text contains
146: the .Nm macro, groff somehow understands to treat the .Nm as an in-line
147: macro, while mandoc treats it as a block macro and breaks the line.
148: No idea how the logic for distinguishing in-line and block instances
149: should be, needs investigation.

1.209 schwarze 184:
185: - In a matrix, break the output line after each matrix line.
1.287 schwarze 186: Found in the discussion at CDBUG 2015. Suggested by Avi Weinstock.
187: This may not be the ideal solution after all: eqn(7) matrices
188: are lists of columns, so Avi's proposal would show each *column*
189: on its own *line*, which is likely to cause confusion.
190: A better solution, but much harder to implement, would be to
191: actually show the coordinates of column vectors on different
192: terminal output lines, using the clumnated output facilities
193: developed for .Bl -tag, .Bl -column, and also used for tbl(7).

207: - GNU eqn converts some operators to special characters, for example,
208: input HYPHEN-MINUS becomes output \(mi, unless it is part of a
209: quoted word. mandoc(1) only does this when the operator is
210: surrounded by blanks, not when it is part of an unquoted word.
