Many issues are annotated for difficulty as follows: |
|
|
|
- loc = locality of the issue |
|
* single file issue, affects file only, or very few |
|
** single module issue, affects several files of one module |
|
*** cross-module issue, significantly impacts multiple modules |
|
and may require substantial changes to internal interfaces |
|
- exist = difficulty of the existing code in this area |
|
* affected code is straightforward and easy to read and change |
|
** affected code is somewhat complex, but once you understand |
|
the design, not particularly difficult to understand |
|
*** affected code uses a special, exceptionally tricky design |
|
- algo = difficulty of the new algorithm to be written |
|
* the required logic and code is straightforward |
|
** the required logic is somewhat complex and needs a careful design |
|
*** the required logic is exceptionally tricky, |
|
maybe an approach to solve that is not even known yet |
|
- size = the amount of code to be written or changed |
|
* a small number of lines (at most 100, usually much less) |
|
** a considerable amount of code (several dozen to a few hundred) |
|
*** a large amount of code (many hundreds, maybe thousands) |
|
- imp = importance of the issue |
|
* mostly for completeness |
|
** would be nice to have |
|
*** issue causes considerable inconvenience |
|
|
|
Obviously, as the issues have not been solved yet, these annotations |
|
are mere guesses, and some may be wrong. |

- The abort() in bufcat(), html.c, can be triggered via buffmt_includes() |
|
by running -Thtml -Oincludes on a file containing a long .In argument. |
|
Fixing this will probably require reworking the whole bufcat() concept. |

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

|

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

- %A doesn't put an "and" before the final author name. |
- .%T can have trailing punctuation. Currently, it puts the trailing |
|
punctuation into a trailing MDOC_TEXT element inside its own scope. |
|
That element should rather be outside its scope, such that the |
|
punctuation does not get underlines. This is not trivial to |
|
implement because .%T then needs some features of in_line_eoln() - |
|
slurp all arguments into one single text element - and one feature |
|
of in_line() - put trailing punctuation out of scope. |

- .%T should be quoted, not underlined, when .%J is also present, |
- .Fn reopens a new scope after punctuation in mandoc, |
to better distinguish the contents of .%T and .%J, |
but closes its scope for good in groff. |
see for example OpenBSD cat(1) |
Do we want to change mandoc or groff? |

- The characters "|" and "\*(Ba" should never be bold, |
- .Nx 1.0a |
not even in the middle of a word, e.g. ".Cm b\*(Bac" in |
should be "NetBSD 1.0A", not "NetBSD 1.0a", |
"mknod [-m mode] name b|c major minor" |
see OpenBSD ccdconfig(8). |

|
- A bogus .Pp between two .It must not produce a double blank line, |
- In .Bl -tag, if a tag exceeds the right margin and must be continued |
see between -R and -r in OpenBSD rm(1). |
on the next line, it must be indented by -width, not width+1; |
|
see "rule block|pass" in OpenBSD ifconfig(8). |
|

|
|
|
- When the -width string contains macros, the macros must be rendered |
|
before measuring the width, for example |
|
.Bl -tag -width ".Dv message" |
|
in magic(5), located in src/usr.bin/file, is the same |
|
as -width 7n, not -width 11n. |
|
The same applies to .Bl -column column widths; |

An easy partial fix would be to just skip the first word if it starts |
|
with a dot, including any following white space, when measuring. |

|
|
- The \& zero-width character counts as output. |
|
That is, when it is alone on a line between two .Pp, |
|
we want three blank lines, not two as in mandoc. |

- Sequences of multiple man(7) paragraphs (.PP, .IP) interspersed |

- another example of the same problem: |
- We use the input line number at several places to distinguish |
.Bl -tag -width "\eD{format}XX" -compact |
same-line from different-line input. That plainly doesn't work |
in OpenBSD ksh(1) gives the wrong width |
with user-defined macros, leading to random breakage. |
because "\e" is one character in groff, two in mandoc |

- Find better ways to prevent endless loops |

Update both mdoc(7) and man(7) documentation. |
