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.

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

105: we don't have either.

1.42 schwarze 135:
136: - inside `.Bl -column' phrases, punctuation is handled like normal
137: text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
138:
139: - inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
140: is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."

1.12 kristaps 142:

149: that one uses NOMBRE because it is spanish...
150: deraadt tends to think that section-dependent macro behaviour

1.174 schwarze 153:
1.109 schwarze 154: - When there is free text in the SYNOPSIS and that free text contains
155: the .Nm macro, groff somehow understands to treat the .Nm as an in-line
156: macro, while mandoc treats it as a block macro and breaks the line.
157: No idea how the logic for distinguishing in-line and block instances
158: should be, needs investigation.
