- 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. |

- .Bd -centered implies -filled, not -unfilled, which is not |
| from kristaps@ Fri, 11 Sep 2009 17:10:53 +0200 |
easy to implement; it requires code similar to .ce, which |
| |
we don't have either. |
| |
Besides, groff has bug causing text right *before* .Bd -centered |
| |
to be centered as well. |
| |
|
| |
- .Bd -filled should not be the same as .Bd -ragged, but align both |
| |
the left and right margin. In groff, it is implemented in terms |
| |
of .ad b, which we don't have either. Found in cksum(1). |
| |
|
| |
- implement blank `Bl -column', such as |
| |
.Bl -column |
| |
.It foo Ta bar |
| |
.El |
| |
|
| |
- explicitly disallow nested `Bl -column', which would clobber internal |
| |
flags defined for struct mdoc_macro |
| |
|
| |
- In .Bl -column .It, the end of the line probably has to be regarded |
| |
as an implicit .Ta, if there could be one, see the following mildly |
| |
ugly code from login.conf(5): |
| |
.Bl -column minpasswordlen program xetcxmotd |
| |

| |
- inside `.Bl -column' phrases, punctuation is handled like normal |
| |
text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -." |
| |
|
| |
- inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf' |
| |
is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab." |
| |
but should give "ab ." |
| |
|
| |
- set a meaningful default if no `Bl' list type is assigned |
| |
|
| |
- have a blank `It' head for `Bl -tag' not puke |
| |
|
| |
- check whether it is correct that `D1' uses INDENT+1; |
| |
does it need its own constant? |
| |
|
| |
- prohibit `Nm' from having non-text HEAD children |
| |
(e.g., NetBSD mDNSShared/dns-sd.1) |
| |
(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified) |
| |
|
| |
- support translated section names |
| |
e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first |
| |
that one uses NOMBRE because it is spanish... |
| |
deraadt tends to think that section-dependent macro behaviour |
| |
is a bad idea in the first place, so this may be irrelevant |
| |
|
| |
- 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. |

- When makewhatis(8) encounters a FATAL parse error, |
| |
it silently treats the file as formatted, which makes no sense |
| |
at all for paths like man1/foo.1 - and which also contradicts |
| |
what the manual says at the end of the description. |
| |
The end result will be ENOENT for file names returned |
| |
by mansearch() in manpage.file. |
| |
|
| |
- makewhatis(8) for preformatted pages: |
| |
parse the section number from the header line |
| |
and compare to the section number from the directory name |
| |
|
| |
- Does makewhatis(8) detect missing NAME sections, missing names, |
| |
and missing descriptions in all the file formats? |

|
| |
- clean up escape sequence handling, creating three classes: |
| |
(1) fully implemented, or parsed and ignored without loss of content |
| |
(2) unimplemented, potentially causing loss of content |
| |
or serious mangling of formatting (e.g. \n) -> ERROR |
| |
see textproc/mgdiff(1) for nice examples |

(3) undefined, just output the character -> perhaps WARNING |

| - nroff inserts a space before :, mandoc doesn't: |
- .%T can have trailing punctuation. Currently, it puts the trailing |
| .Dl expr "/$a" Li : '.*/\e(.*\e)' |
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". |

|
| |
- Trailing punctuation after .%T triggers EOS spacing, at least |
| |
outside .Rs (eek!). Simply setting ARGSFL_DELIM for .%T is not |

the right solution, it sends mandoc into an endless loop. |

| - OpenBSD::PackageName(3p) has "if (block) 90:1" in the parse tree |
- check that MANDOCERR_BADTAB is thrown in the right cases, |
| |
i.e. when finding a literal tab character in fill mode, |
| |
and possibly change the wording of the warning message |
| |
to refer to fill mode, not literal mode |

- warn about "new sentence, new line" |
| |
|
| |
- mandoc_special does not really check the escape sequence, |
| |
but just the overall format |
| |
|
| |
- integrate mdoclint into mandoc ("end-of-line whitespace" thread) |

| Several areas can be cleaned up to make mandoc even faster. These are |
- mention hyphenation rules: |
| |
breaking at letter-letter in text mode (not macro args) |
| |
proper hyphenation is unimplemented |
| |
|
| - cache `Bd' display types as `Bl' types are cached (this primarily |
- talk about spacing around delimiters |
| improves code-size by removing the a2disp type functions) |

| |
|
| - improve caching mechanism to handle other per-element arguments so |
- mark macros as: page structure domain, manual domain, general text domain |
| that they need not be recalculated between front- and back-ends (also |
is this useful? |
| reduces code size and complexity) |
|
| |
|
| |
- mention /usr/share/misc/mdoc.template in mdoc(7)? |

- the PDF file is HUGE: this can be reduced by using relative offsets |
| |
|
| |
- instead of re-initialising the roff predefined-strings set before each |
| |
parse, create a read-only version the first time and copy it |
| |

- We use the input line number at several places to distinguish |
| |
same-line from different-line input. That plainly doesn't work |
| |
with user-defined macros, leading to random breakage. |
| |
|
| |
- Find better ways to prevent endless loops |
| |
in roff(7) macro and string expansion. |
| |
|
| |
- Finish cleanup of date handling. |
| |
Decide which formats should be recognized where. |
| |
Update both mdoc(7) and man(7) documentation. |

- Consider creating some views that will make the database more |
| |
readable from the sqlite3 shell. Consider using them to |
| |
abstract from the database structure, too. |
