between the sentences. Thomas Klausner says he has seen some
of these, and i don't see any false positives.

Also catch cases where the new sentence starts with a one-letter word
and the input line is broken right after that word.
Suggested by Thomas Klausner <wiz @ NetBSD>.
It's merely a three-bit diff, changing one byte from 0x34 to 0x33,
so what can possibly go wrong...

second step: make the per-column byte pointer persistent across
term_flushln() calls, such that a subsequent call can continue at
the point where the previous call left. If more than one column
is in use, return from term_flushln() when the column is full,
rather than breaking the output line.
No functional change, because nothing sets up multiple columns yet.
|
| |
|
|
|
|
| |
first step: split column data out of the terminal state struct into
a new column state struct and use an array of such column state
structs. No functional change.

and after that, previously written output gets overwritten, but
overwriting with blanks does *not* erase previously written content.
Yes, manual pages exist that are crazy enough to rely on that...

Renaming a user-defined macro is very simple: just copy
the definition to the new name and delete the old name.
Renaming high-level macros is a bit tricky: use a dedicated
key-value-table, with non-standard names as keys and standard
names as values. When a macro is found that is not user-defined,
look it up in the "renamed" table and translate it back to the
standard name before passing it on to the high-level parsers.

Contrary to groff, high-level macros abort .ce mode for now.

The Tcl/Tk manual pages use this extensively.
Delete the TERM_MAXMARGIN hack, it breaks .mc inside .nf;
instead, implement a proper TERMP_BRNEVER flag.

Eliminate the "overstep" state variable.
The information is already contained in "viscol".
Minus 60 lines of code, no functional change intended.

(escape character control), touching nothing after the preprocessing
stage and keeping even the state variable local to the preprocessor.
Since the escape character is also used for line continuation, this
requires pulling the implementation of line continuation from the
input reader to the preprocessor, which also considerably shortens
the code required for that.
When the escape character is changed, simply let the preprocessor
replace bare by escaped backslashes and instances of the non-standard
escape character with bare backslashes - that's all we need.
Oh, and if anybody dares to use these requests in OpenBSD manuals,
sending a medium-sized pack of axe-murderers after them might be a
worthwhile part of the punishment, but probably insuffient on its own.

strange groff edge case behaviour found in multimedia/mjpegtools
|
| | |
|
| |
|
|
|

|
|
|
|
|

A full implementation would require access to output device properties
and state variables (both only available after the main parser has
finalized the parse tree) before numerical expansions in the roff
preprocessor (i.e., before the main parser is even started).
Not trying to pull that stunt right now because the static-width
implementation committed here is sufficient for tcl-style manual pages
and already more complicated than i would have suspected.

and of called macros.
This bug affects almost all macros, and fixing it simplifies the
code. It is amazing that the bogus ARGS_QWORD feature got implemented
in the first place, and then carrier along for more than eight years
without anybody ever noticing that it was pointless.

man(1) does not ignore manpath directories lacking mandoc.db(5) files;

When pkg_add(1)ing packages installing manual pages into some directory,
the database in that directory automatically gets created or updated,
no change so far. This patch causes the database file to be
automatically unlinked when pkg_delete(1)ing the last package having
manual pages in that directory, to leave less cruft behind.

Just let HTML <table> do its work of selecting the needed width.

Switch -W all from meaning -W warning to meaning -W style.
The meaning of -T lint does *not* change, it still implies -W warning.
No messages on the new level yet, but they will come.
Usually, i do not lightly make the user interface larger.
But this has been planned for years, and EXIT STATUS 1
was reserved for it all the time. The message system
is now stable enough to finally implement it.

1. I forgot about the 2n padding between tag and body.
2. The factor 1.1 was too small for bold fold, make it *1.15 + 1n.

got committed to groff which changed .TP from using .it to using .itc,
such that groff now supports more than one man(7) macro line in the .TP
head if all but the last line in the head end with \c.
Of course, relying on that behaviour is utterly non-portable, but if
authors are reckless enough to use that idiom, let's do what they want.

widths of the remaining columns is already wider than the line
length, underflowing size_t and dying from ENOMEM is the wrong plan.
Instead, simply refrain from expanding anything in such a situation,
avoiding a crash that tb@ found with afl.
