Introduce a new mdoc(7) macro .Tg ("tag") to explicitly mark a place
as defining a term.  Please only use it when automatic tagging does
not work.  Manual page authors will not be required to add the new
macro; using it remains optional.  HTML output is still rudimentary
in this version and will be polished later.

Thanks to kn@ for reminding me that i have been considering since
BSDCan 2014 whether something like this might be useful.  Given
that possibilities of making automatic tagging better are running
out and there are still several situations where automatic tagging
cannot do the job, i think the time is now ripe.

Feedback and no objection from millert@; OK espie@ inoguchi@ kn@.

Align to the new, sane behaviour of the groff_mdoc(7) .Dd macro:
without an argument, use the empty string, and always concatenate
all arguments, no matter their number.
This allows reducing the number of arguments of mandoc_normdate()
and some other simplifications, at the same time polishing some
error messages by adding the name of the macro in question.

If messages are shown and output is printed without a pager, display
a heads-up on stderr at the end because otherwise, users may easily
miss the messages: because messages typically occur while parsing,
they typically preceed the output.  This is most useful with flag
combinations like "-c -W all" but may also help in some unusual
error scenarios.
Inconvenient ordering of output originally pointed out by espie@
for the example situation that /tmp/ is not writeable.

Some time ago, i simplified mandoc_msg() such that it can be used
everywhere and not only in the parsers.
For more uniform messages, use it at more places instead of err(3),
in particular in the main program.
While here, integrate a few trivial functions called at exactly one
place into the main option parser, and let a few more functions use
the normal convention of returning 0 for success and -1 for error.

Yet another round of improvements to manual font selection.

Unify handling of \f and .ft.
Support \f4 (bold+italic).
Support ".ft BI" and ".ft CW" for terminal output.
Support the .ft request in HTML output.
Reject the bogus fonts \f(C1, \f(C2, \f(C3, and \f(CP.
In regress.pl, only strip leading whitespace in math mode.

Several improvements to escape sequence handling.

* Add the missing special character \_ (underscore).
* Partial implementations of \a (leader character)
and \E (uninterpreted escape character).
* Parse and ignore \r (reverse line feed).
* Add a WARNING message about undefined escape sequences.
* Add an UNSUPP message about unsupported escape sequences.
* Mark \! and \? (transparent throughput)
and \O (suppress output) as unsupported.
* Treat the various variants of zero-width spaces as one-byte escape
sequences rather than as special characters, to avoid defining bogus
forms with square brackets.
* For special characters with one-byte names, do not define bogus
forms with square brackets, except for \[-], which is valid.
* In the form with square brackets, undefined special characters do not
fall back to printing the name verbatim, not even for one-byte names.
* Starting a special character name with a blank is an error.
* Undefined escape sequences never abort formatting of the input
string, not even in HTML output mode.
* Document the newly handled escapes, and a few that were missing.
* Regression tests for most of the above.

Almost mechanical diff to remove the "struct mparse *" argument
from mandoc_msg(), where it is no longer used.
While here, rename mandoc_vmsg() to mandoc_msg() and retire the
old version:  There is really no point in having another function
merely to save "%s" in a few places.
Minus 140 lines of code.

Major cleanup; may imply minor changes in edge cases of error reporting.

Finally, drop support for the run-time configurable mandocmsg()
callback.  It was over-engineered from the start, never used for
anything in a decade, and repeatedly caused maintenance headaches.

Consolidate reporting infrastructure into two files, mandoc.h and
mandoc_msg.c, mopping up the bits and pieces that were scattered
around main.c, read.c, mandoc_parse.h, libmandoc.h, the prototypes
of four parsing-related functions, and both parser structs.

Cleanup, no functional change:
Split the top level parser interface out of the utility header
mandoc.h, into a new header mandoc_parse.h, for use in the main
program and in the main parser only.
Move enum mandoc_os into roff.h because struct roff_man is the
place where it is stored.
This allows removal of mandoc.h from seven files in low-level
parsers and in formatters.

Implement the \f(CW and \f(CR (constant width font) escape sequences
for HTML output.  Somewhat relevant because pod2man(1) relies on this.
Missing feature reported by Pali dot Rohar at gmail dot com.

Note that constant width font was already correctly selected before
this when required by semantic markup.  Only attempting physical
markup with the low-level escape sequence was ineffective.

Rudimentary implementation of the roff(7) .char (output glyph
definition) request, used for example by groff_hdtbl(7).

This simplistic implementation may interact incorrectly
with the .tr (input character translation) request.
But come on, you are not only using .char *and* .tr, but you do so
with respect to the same character in the same manual page?

Rudimentary implementation of the roff(7) .while request.
Needed for example by groff_hdtbl(7).

There are two limitations:
It does not support nested .while requests yet,
and each .while loop must start and end in the same scope.

The roff_parseln() return codes are now more flexible
and allow OR'ing options.

The upcoming .while request will have to re-execute roff(7) lines
parsed earlier, so they will have to be saved for reuse - but the
read.c preparser does not know yet whether a line contains a .while
request before passing it to the roff parser.  To cope with that,
save all parsed lines for now.  Even shortens the code by 20 lines.

Implement the roff(7) .shift and .return requests,
for example used by groff_hdtbl(7) and groff_mom(7).

Also correctly interpolate arguments during nested macro execution
even after .shift and .return, implemented using a stack of argument
arrays.

Note that only read.c, but not roff.c can detect the end of a macro
execution, and the existence of .shift implies that arguments cannot
be interpolated up front, so unfortunately, this includes a partial
revert of roff.c rev. 1.337, moving argument interpolation back into
the function roff_res().

Issue a STYLE message when normalizing the date format in .Dd/.TH.
Leah Neukirchen pointed out that mdoclint(1) used to warn about a
leading zero before the day number, so we know that both NetBSD and
Void Linux want the message.  It does no harm on OpenBSD because
Mdocdate always does the right thing anyway.

Split -Wstyle into -Wstyle and the even lower -Wbase, and add

Please use just "-Tlint" to check base system manuals (defaulting
to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the
manuals of portable software projects you maintain that are not
part of OpenBSD base, to avoid bogus recommendations about base
system conventions that do not apply.

Partial implementation of \h (horizontal line drawing function).
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.

Introduce a new mandoc(1) message level, -W style, below -W warning.
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.

jmc@ regarding the concept: "really good idea"

Add a warning "new sentence, new line".
This does not attempt to pinpoint each and every offender, but
instead tries very hard to avoid false positives: Currently, there
are only two false positives in the whole OpenBSD base system.
Only do this in mdoc(7), not in man(7), because manuals written
in man(7) typically have much worse problems than this.
OK jmc@ on a previous version of the patch

Delete complicated code dealing with .Bl -tag without -width,

traditional -width Ds that is still in widespread use.

I just pushed a patch upstream to GNU roff that does the same for
groff_mdoc(7).  Before, groff contained code that was even more
complicated than mandoc, but both resulted in quite different
user-visible output.  Now, both agree, and output is nicer for both.

In private header files, __BEGIN_DECLS and __END_DECLS are pointless.
Because these work slightly differently on different systems,
they are becoming a maintenance burden in the portable version,
so delete them.

Besides, one of the chief design goals of the mandoc toolbox is to
make sure that nothing related to documentation requires C++.
Consequently, linking mandoc against any kind of C++ program would
defeat the purpose and is not supported.

Major character table cleanup:
* Use ohash(3) rather than a hand-rolled hash table.
* Make the character table static in the chars.c module:
There is no need to pass a pointer around, we most certainly
never want to use two different character tables concurrently.
* No need to keep the characters in a separate file chars.in;
that merely encourages downstream porters to mess with them.
* Sort the characters to agree with the mandoc_chars(7) manual page.
* Specify Unicode codepoints in hex, not decimal (that's the detail
that originally triggered this patch).
No functional change, minus 100 LOC, and i don't see a performance change.

Improve error handling in the eqn(7) parser.
Get rid of the first fatal error, MANDOCERR_EQNSYNT.
In eqn(7), there is no need to be bug-compatible with groff, so there
is no need to abondon the whole equation in case of a syntax error.

In particular:
* Skip "back", "delim", "down", "fwd", "gfont", "gsize", "left",
  "right", "size", and "up" without arguments.
* Skip "gsize" and "size" with a non-numeric argument.
* Skip closing delimiters that are not open.
* Skip "above" outside piles.
* For diacritic marks and binary operators without a left operand,
  default to an empty box.
* Let piles and matrices take one argument rather than insisting
  on a braced list.  Let HTML output handle that, too.
* When rewinding, if the root box is guaranteed to match
  the termination condition, no error handling is needed.

Re-write of eqn(7) parser and MathML output.
This adds parser-level support for the grammar described by the eqn
second-edition technical paper, "Typesetting Mathematics — User's Guide"
(Kernighan, Cherry).
The reason for this re-write is the grouping rules, which were not
possible given the existing implementation.
The re-write has also considerably simplified the HTML (and, if it ever
is completed, terminal) front-end.

the column lists.
This gets rid of one of the last useless FATAL errors

This fixes an issue introduced more than five years ago, at first
causing an assert() since mdoc_action.c rev. 1.14 (June 17, 2009),
then later a FATAL error since mdoc_validate rev. 1.130 (Nov. 30, 2010),

One of the WARNING messages has to use the word "section" twice in two
different meanings, that cannot be helped.  But we can make this less
confusing by stating that the second instance refers to stuff like (2),

Rudimentary implementation of the .it request (input line trap).
As with any low-level roff request involving subtle interactions
with macro internals, this implementation is not exact, but it
does handle the simplest cases.

This request occurs in man(7) code generated from DocBook,
for example mysql(1) and yasm_arch(7).
Thanks to brad@ for reporting the issue back in January 2011.

The name "struct tbl" was badly misleading for two reasons:
1) This struct almost exclusively contains the table options.
2) Information about the table as a whole is actually in "struct tbl_node".
Besides, "struct tbl" was almost impossible to search for.
So rename it to "struct tbl_opts".  No functional change.

Implement the roff \z escape sequence, intended to output the next
character without advancing the cursor position; implement it to
simply skip the next character, as it will usually be overwritten.

With this change, the pod2man(1) preamble user-defined string \*:,
intended to render as a diaeresis or umlaut diacritic above the
preceding character, is rendered in a slightly less ugly way,
though still not correctly.  It was rendered as "z.." and is now
rendered as ".".

Given that the definition of \*: uses elaborate manual \h positioning,
there is little chance for mandoc(1) to ever render it correctly,
but at least we can refrain from printing out a spurious "z", and
we can make the \z do something semi-reasonable for easier cases.

Do not handle vertical lines as additional tbl(7) columns,
instead save their properties with the following column.
This simplifies layout parsing and saves a lot of code
related to column handling.

At output time, print all white space and vertical lines
separating columns before printing the following column,
and none after printing the preceding column, considerably
simplifying white space handling and width calculations.

No functional change, but it saves 150 lines of code,
and it allows the next patch to tbl_term.c, tbl_literal().

If -Tman is specified and input is -man, echo the preprocessed (`so'
replaced by file) input.  This replaces earlier behaviour of doing
nothing, which I found unexpected (mandoc should always output).

This requires a buffer in read.c that saves the input lines before being
parsed, with a special hook if `so' is invoked.  This buffer is just
flushed to output if -mman is the input.

While mucking around doing this, I also alpha-ordered the mandoc.h
functions.

Ok schwarze@, with no screaming when the polished patch was published.

Move "chars" interface out of out.h and into mandoc.h.  This doesn't
change any code but for renaming functions and types to be consistent
with other mandoc.h stuff.  The reason for moving into libmandoc is that
the rendering of special characters is part of mandoc itself---not an
external part.  From mandoc(1)'s perspective, this changes nothing, but
for other utilities, it's important to have these part of libmandoc.
Note this isn't documented [yet] in mandoc.3 because there are some
parts I'd like to change around beforehand.

Remove a2roffdeco() and mandoc_special() functions and replace them with
a public (mandoc.h) function mandoc_escape(), which merges the
functionality of both prior functions.

Reason: code duplication.  The a2roffdeco() and mandoc_special()
functions were pretty much the same thing and both quite complex.  This
allows one function to receive improvements in (e.g.) subexpression
handling and performance, instead of having to replicate functionality.

As such, the mandoc_escape() function already handles a superset of the
escapes handled in previous versions and has improvements in performance
(using strcspn(), for example) and reliable handling of subexpressions.

This code Works For Me, but may need work to catch any regressions.
Since the benefits are great (leaner code, simpler API), I'd rather have
it in-tree than floating as a patch.

Add initial EQN support to mandoc.  This parses, then throws away, data
between EQ and EN roff blocks.  EQN is different from TBL in that data
after .EQ is unilaterally considered an equation until an .EN.  Thus,
there's no need to jump through hoops in having table spans and so on.
This is ONLY the parse code framework in libroff.  EQN is not yet passed
into the backends.

Refactoring in preparation for .rm support:
Unify parsing of names given as roff request arguments into a new
function roff_getname(), which is rather different from the parsing
function for normal arguments, mandoc_getarg(), because names cannot
be quoted and cannot contain whitespace or escaped characters.
The new function now throws an ERROR when finding escaped characters
in a name.

Make width calculations occur within tbl_term.c, not tbl.c.  This allows
for front-ends to make decisions about widths, not the back-end.

To pull this off, first make each tbl_head contain a unique index value
(0 <= index < total tbl_head elements) and remove the tbl_calc() routine
from the back-end.

Then, when encountering the first tbl_span in the front-end, dynamically
create an array of configurations (termp_tbl) keyed on each tbl_head's
unique index value.  Construct the decimals and widths at this time,
then continue parsing as before.

The termp_tbl and indexes are required because we pass a const tbl AST
into the front-end.

Plug in the "head" concept for tables.  A tbl_head specifies the full

for a row and iterates through each entry, plugging data from the

is verbatim except that lists macros are made into hard-coded lists (for

Implement a simple, consistent user interface for error handling.
We now have sufficient practical experience to know what we want,
so this is intended to be final:
- provide -Wlevel (warning, error or fatal) to select what you care about
- provide -Wstop to stop after parsing a file with warnings you care about
- provide consistent exit status codes for those warnings you care about
- fully document what warnings, errors and fatal errors mean
- remove all other cruft from the user interface, less is more:
- remove all -f knobs along with the whole -f option
- remove the old -Werror because calling warnings "fatal" is silly
- always finish parsing each file, unless fatal errors prevent that
This commit also includes a couple of related simplifications behind
the scenes regarding error handling.
Feedback and OK  kristaps@;  Joerg Sonnenberger (NetBSD) and
Sascha Wildner (DragonFly BSD) agree with the general direction.
