6 Many issues are annotated for difficulty as follows:
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
32 Obviously, as the issues have not been solved yet, these annotations
33 are mere guesses, and some may be wrong.

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
72 .de .als .rm .de only changes the new value, not the alias.

127 - inside `.Bl -column' phrases, punctuation is handled like normal
128 text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
130 - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
131 is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
132 but should give "ab ."
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)
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
142 is a bad idea in the first place, so this may be irrelevant
143 loc ** exist ** algo ** size * imp **
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.

183 --- missing eqn features -----------------------------------------------
185 - In a matrix, break the output line after each matrix line.
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).
194 loc * exist * algo ** size ** imp **
196 - The "size" keyword is parsed, but ignored by the formatter.
197 loc * exist * algo * size * imp *

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.
211 Also, check whether there are more such cases (e.g., +?).

322 - .%T can have trailing punctuation. Currently, it puts the trailing
323 punctuation into a trailing MDOC_TEXT element inside its own scope.
324 That element should rather be outside its scope, such that the
325 punctuation does not get underlines. This is not trivial to
326 implement because .%T then needs some features of in_line_eoln() -
327 slurp all arguments into one single text element - and one feature
328 of in_line() - put trailing punctuation out of scope.
329 Found in mount_nfs(8) and exports(5), search for "Appendix".

332 - Trailing punctuation after .%T triggers EOS spacing, at least

516 - mark macros as: page structure domain, manual domain, general text domain
519 - mention /usr/share/misc/mdoc.template in mdoc(7)?
521 - Is all the content from http://www.std.com/obi/BSD/doc/usd/28.tbl/tbl

528 - the PDF file is HUGE: this can be reduced by using relative offsets

534 - POSIX says in the documentation of sysconf(3) that PATH_MAX
535 is allowed to be so large that it is a bad idea to use it
536 for sizing static buffers. So use dynamic buffers throughout.
537 See the file test-PATH_MAX.c for details.

541 - Is it possible to further simplify ENDBODY_SPACE?
543 - Find better ways to prevent endless loops
544 in roff(7) macro and string expansion.
546 - make buffers for parsing functions const

565 - .Cd # arch1, arch2 in section 4 pages:
566 find better way to indicate multiple architectures, maybe:
567 allow .Dt vgafb 4 "macppc sparc64"
568 already shown as "Device Drivers Manual (macppc sparc64)"
569 for apropos, make that "vgafb(4) - macppc # sparc64" instead of "- all"
570 groff can be made to show multiple arches, too, but it is
571 tedious to do the string parsing in roff code...

582 Do we need to fix existing manuals?
583 Do we need to fix the definition of the mdoc(7) language?
