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.

- \\ 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.

- .Bd -centered implies -filled, not -unfilled, which is not
|
|
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.
|
|
loc *** exist *** algo ** size ** imp ** (parser reorg would help)

|
|
|
- .Bd -filled should not be the same as .Bd -ragged, but align both

- 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 ."
|
|
|
|
- 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
|
|
loc ** exist ** algo ** size * imp **
|
|
|
|
- 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.

- .%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.

try to guess Xr in man(7) for hyperlinking

- The tables used to render the three-part page headers actually force

the width of the <body> to the max-width given for <html>.

Not yet sure how to fix that...

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.

Note that formatting is inconsistent in groff.

Relatively hard because the relevant code is scattered

Several areas can be cleaned up to make mandoc even faster. These are
|
|
|
|
- improve hashing mechanism for macros (quite important: performance)
|
|
|
|
- improve hashing mechanism for characters (not as important)
|
|
|
|
- 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

- POSIX says in the documentation of sysconf(3) that PATH_MAX

is allowed to be so large that it is a bad idea to use it
|

for sizing static buffers. So use dynamic buffers throughout.

See the file test-PATH_MAX.c for details.

- 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.
