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 roff parser doesn't tolerate additional characters between |
- .if n .ce in the middle of .TS data |
| a macro and the \} terminating a conditional block, e.g. |
afl case f1/id:000103,sig:06,src:009024+009105,op:splice,rep:2 (jes@) |
| .if n \{ |
While roff_parseln() prevents .ce and similar requests in the middle |
| .br \} |
of a tbl, the guard is no longer effective when the .ce is wrapped |
| reported by ulrich spoerlein Tue, 19 Oct 2010 20:39:50 +0200 |
in a roff block, for example a conditional. The resulting assertion |
| |
has never been seen in any real-world manual page. |
| |
This is too dangerous to fix before release because it requires |
| |
reorganizing the very delicate internals of roff_parseln(), |
| |
which risks causing more severe bugs. |

- wrong number of layout columns in tbl(7) code generated by -T man |
| |
https://savannah.gnu.org/bugs/?57720 |
| |
The reason likely is that tbl(7) does not support the -Bl -column |
| |
feature of not explicitly specifying the last table column. |

- roff.c, roff_expand() should not remove blanks before comments |
| |
to Oliver Corff, Sep 7, 2021 |
| |
loc * exist * algo * size * imp * |
| |
but watch out for regressions in the high-level parsers |
| |
maybe it should not even remove comments? - consider T{\" |
| |
|
| |
- In the body of conditional requests, escape sequence expansion |
| |
must not be performed if the condition is false. This implies |
| |
the first part of a request line must be expanded before |
| |
request parsing (like it is now), but expansion in the second |
| |
part must be delayed. |

| - pod2man expects `tr' to be implemented for \*(-- to work |
- .als only works for macros in mandoc, not for user-defined strings. |
| |
Also, the "val" field in struct roffkv would have to be replaced |
| |
with a pointer to a reference-counted wrapper, and an alias |
| |
would have to point to the same wrapper as the original. |
| |
.als to undefined does nothing; the alias is not created. |
| |
.rm'ing the original leaves the alias to point to the old value. |
| |
.de .als .de changes both, but |
| |
.de .als .rm .de only changes the new value, not the alias. |

- mandoc replaces all ASCII control characters except tab and line feed |
| |
with '?' during input. It would be better to replace them with |
| |
Unicode escapes in preconv_encode() or somewhere in the vicinity, |
| |
such that the already existing better replacement strings show |
| |
up in the output. Emulating groff is not desirable: groff replaces |
| |
0x00, 0x0b, and 0x0d to 0x1f with the empty string (bad because |
| |
that's easy to overlook for the document author), 0x01 with '.' |
| |
(very confusing), and passes through 0x02 to 0x08, 0x0c, and 0x7f |
| |
raw (bad because that is insecure output). Remember that 0x07 may |
| |
need special handling because it is sometimes used for certain |
| |
delimiters, so it may need handling *after* roff.c rather than before. |
| |
reminded by John Gardner 16 Jun 2020 14:26:28 +1000 |
| |
Actually, more ASCII control characters than just 0x07 may need |
| |
later handling because they can for example be used in macro names. |
| |
So they may need handling after roff(7) processing. |

- 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. |

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

surrounded by blanks, not when it is part of an unquoted word. |

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

- .%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. |
| |
Found in mount_nfs(8) and exports(5), search for "Appendix". |

- Can the distinction between .Vt and .Va be made stricter, |
| |
recommending .Vt extern char * Ns Va optarg ; ? |
| |
What about the block macro properties of .Vt in the SYNOPSIS? |

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