.Bl -tag
.Sm off
.It ...
triggered an assertion, which it shouldn't;
the warning that .Bl -tag "requires the width argument" is enough.
From Joerg Sonnenberger.

modern groff produces three blank lines before the man(7) footer;
from Joerg Sonnenberger.

patch from Joerg Sonnenberger;
this finally fixes the test(1) SYNOPSIS.
|
|
This will eventually be used so that mdoc_macro can know whether to
dump list line arguments into the body (`Bl -column' overflowing).
Remove a2list() and arg_listtype() because of this.
From kristaps@.
While merging, fix a regression in mdoc_term.c, print_bvspace():
The bsd.lv version of this broke vertical spacing in .Bl -column.

sigvec(3) triggers MANDOCERR_BODYLOST, which must not be fatal
|
|
featuring three message levels, as agreed during the mandoc hackathon:
* FATAL parser failure, cannot produce any output from this input file:
eventually, we hope to convert most of these to ERRORs.
* ERROR, meaning mandoc cannot cope fully with the input syntax and will
probably lose information or produce structurally garbled output;
it will try to produce output anyway but exit non-zero at the end,
which is eventually intended to make the ports infrastructure happy.
* WARNING, meaning you should clean up the input file, but output
is probably mostly OK, so this will not cause error-exit at the end.
This commit is mostly just converting the old system to the new one; before
the classification will become really reliable, we must check all messages.
In particular,
* set up a new central message string table in main.c
* drop the old message string tables from man.c and mdoc.c
* get rid of the piece-meal merr enums in libman and libmdoc
* reduce number of error/warning functions from 16 to 6 (still a lot...)
While here, handle a few problems more gracefully:
* allow .Rv and .Ex to work without a prior .Nm
* allow .An to ignore extra arguments
* allow undeclared columns in .Bl -column

* allow roff_parseln() to be re-run
* allow roff_parseln() to manipulate the line buffer offset
* support the offset in the man and mdoc libraries
* adapt .if, .ie, .el, .ig, .am* and .de* support
* interpret some instructions even in conditional-negative context
Coded by kristaps during the last day of the mandoc hackathon.
To avoid regressions in the OpenBSD tree, commit this together
with some small local additions:
* detect roff block end "\}" even on macro lines
* actually implement the ".if n" conditional
* ignore .ds, .rm and .tr in libroff
Also back my old .if/.ie/.el-handling out of libman, reverting:
man.h 1.15 man.c 1.25 man_macro.c 1.15 man_validate.c 1.19
man_action.c 1.15 man_term.c 1.28 man_html.c 1.9.

This is the OpenBSD part of the main step to bring it back in sync.
At the same time, this prevents trailing whitespace in the output:
We delay writing blanks until we are sure printable characters follow.
This is achieved by
* not using vbl any longer for the control of line breaking
* such that vbl can sum up all kinds of white space
* before writing a word, printing all the blanks collected in vbl
* within the word, adding NBSP chars to vbl, then continuing with the word
* after the word, adding blanks to vbl, then starting the next word
|
|
to make it easier to understand and to fix various bugs:
* strip white space from the end MDOC_TEXT elements in literal mode
* in literal mode, a line may be blank even when containing tabs
* escaped backslashes do not escape following characters

but in practice, most real legacy man(7)uals are using so much
low level roff that we can't really get away without at least
partially handling some roff instructions.
As doing this in man(7) only has become messy and as even some
mdoc(7) pages need it, start a minimal partial roff preprocessor.
As a first step, move handling of .am[i], .de[i] and .ig there.
Do not use the roff preprocessor for new manuals!
Now that we have three main parser libraries - roff, man and mdoc -
each one having its own error handling is becoming messy, too.
Thus, start unifying message handling in one central place,
introducing a new generic function mmsg().

* Flag errors and warnings in global variables.
* Exit with error code if either is not null on exit.
* Push down the buffers to the functions using them.
* Handle the stdin/file argument in one function.
* Use mmap when possible or else read the whole file into a single buffer.
* Push buffer resizing into its own function.
|
|
* If the last -column .Bl isn't specified, it is auto-sized.
* An invalid .St argument should be a warning, not an error.
Just put the argument into the output.
* An invalid .At argument should be a warning, not an error.
Just print the argument, like new groff does.
* Remove warnings concerning manual section (like 1, 6, 8).
It was only used for .Ex and not really useful.
* Remove warnings concerning page section (like SYNOPSIS).
These were only used for .Fd and .Lb and not really useful.

Only OPEN are drawn before the beginning of a macro;
this is new, before this, MIDDLE ('|') were drawn in front, too.
Only CLOSE are pushed after the end of a macro (as before).

This allows us to finally enable handling of leading punctuation
without regressions.

which is simpler and more powerful than mine, and remove mine.
* man(7) now has EOS handling, too
* put EOS detection into its own function in libmandoc
* use node and termp flags to communicate the EOS condition
* no more EOS pseudo-macro
* no more non-printable EOS marker character on the formatter level
This slightly breaks EOS detection after trailing punctuation
in mdoc(7) macros, but that will be restored soon.

this does not merge kristaps' end-of-sentences handling yet,
i will check that separately. This one includes:
* handle \*(Ba as a delimiter
* introduce ARGS_PEND for .Bl -column .It end-of-line special casing
* section ordering: expect EXIT STATUS at the right place
* line break fixes in SYNOPSIS
* allow literal contexts to have arbitrary line lengths
* the input file column number can not be used to identify the beginning
of a line because white space is allowed after the initial '.'
* proper leading spaces in -man -Tascii mode
* do not let Lb break lines in -mdoc -Thtml LIBRARY
|
|
* preserve multiple consecutive space characters in input
* do not restrict .Cd and .Rv to certain sections (requested by Joerg)
* do not run lookup() on quoted words
* enum return types for mdoc_args and mdoc_argv
* fix auto-closing of LINK tag in -Txhtml (from Daniel Friesel)
* various lint and manual fixes

This option was not useful, you never want mandoc to die
just because there is an invalid character in the input file,
neither in production nor when linting: a warning is sufficient.
This was particularly annoying because it was part of -fstrict
and could not be switched off.

ruin indentation of the next line in the SYNOPSIS section;
bug found by jacekm@ in err(3)

When converting blank lines to .Pp outside literal context,
it could happen that the following node ended up as a child
of the .Pp element, but it must always be a sibling.

and outside. In literal context, tab stops are at each eigth column;
outside, they are at each fifth column.
Use tabwidth = 5 as the default and temporarily switch to 8 in termp_bd_pre().
This requires to move the term_flushln() of the final line of a display from
termp_bd_post() to termp_bd_pre(); the former still needs term_newln()
to handle the final lines of non-literal displays.
Handling inside term_flushln() is tricky because a tab collapses with
inter-word spacing, but not with another tab.
Missing feature reported independently by jmc@ and deraadt@.
|
|
When finding a blank line, trying to parse it is a bad idea.
Instead, after adding .Pp to the AST, just return from parsetext().
|
|
another problem reported by jmc@.
The physical output line may contain output from more than one buffer.
Thus, to decide whether a line break is needed, it's insufficient to
only look at the number of bytes in the current output buffer.
Keep track of the number of characters already written, too.

because jmc@ noticed that it broke blank lines in literal displays.
The original idea was to suppress stray blank lines.
But we don't want to suppress *all* blank lines,
instead just those caused by nested lists.
So do the check whether there was any output on this line,
i.e. whether or not to break the line,
at the right place, which is after processing the .It body.

avoid the bad parts of 1.9.23, and keep local patches.
Input in general:
* Basic handling of roff-style font escapes \f, \F.
* Quoted punctuation does not count as punctuation.
mdoc(7) parser:
* Make .Pf callable; noted by Claus Assmann.
* Let .Bd and .Bl ignore unknown arguments; noted by deraadt@.
* Do not warn when .Er is used outside certain sections.
* Replace mdoc_node_free[list] by mdoc_node_delete.
* Replace #define by enum for rew*() return values.
man(7) parser:
* When .TH is missing, use default section and date.
Output in general:
* Curly braces do not count as punctuation.
* No space after .Fl w/o args when a macro follows on the same line.
HTML output:
* Unify PAIR_*_INIT macros, introduce new PAIR_ID_INIT().
* Print whitespace after, not before .Vt .Fn .Ft .Fo.
Checked that all manuals in base still build.
