2012-09-11  Ralph Corderoy <ralph@inputplus.co.uk>
	    Werner LEMBERG  <wl@gnu.org>

	* src/preproc/tbl/tbl.man: Better document `d' column specifier.

2012-08-31  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Add `pdfmom' to handle mom documents with gropdf.

2012-08-08  Eric S. Raymond  <esr@thyrsus.com>

	TBLization, as discussed on the list.  There's a rewrite of
	this file in panning, but this gets the content clean for now.

	* tmac/groff_mdoc.man: In this file.

2012-08-09  Werner LEMBERG  <wl@gnu.org>

	Provide proper Unicode mapping from and to dotless j.

	Elimination of nasty presentation-level macro tangles makes
	structural translation to XML possible.

	* man/groff_char.man: Clean up the mess, use real TBL tables.

2012-07-23  Eric S. Raymond  <esr@thyrsus.com>

	More elimination of low-level troff hackery in the documentation
	so it can be lifted to structural markup.

	* tmac/groff_me.man: Use TBL rather than wacky diversions and .ti
	requests.

2012-07-24  Werner LEMBERG  <wl@gnu.org>

	* src/preproc/eqn/eqn.man, src/preproc/grn/grnn.man,
	src/devices/grodvi/grodvi.man, src/devices/grolj4/grolj4.man,
	src/devices/grops/grops.man, src/utils/lkbib/lkbib.man,
	src/utils/indxbib/indxbib.man, src/utils/tfmtodit/tfmtodit.man,
	src/utils/xtotroff/xtotroff.man:
	Remove running text in the synopses of various manual pages,
	as it badly screws up attempts to mechanically parse them.

	* contrib/mom/groff_mom.man: Use .URL rather than .UR/.UE, as this is
	now preferred for manual pages.

2012-07-03  Werner LEMBERG  <wl@gnu.org>

	Fix Unicode mapping of Greek stroked and curly phi.

	Problem reported by Alkis Georgopoulos <alkisg@gmail.com>;

	This does the same as the previous commit.

2012-05-24  Denis M. Wilson  <dmw@oxytropis.plus.com>

	See

	  http://lists.gnu.org/archive/html/bug-groff/2012-05/msg00000.html

	for the report and the bug fix.

2012-05-24  Ivan Shmakov  <oneingray@gmail.com>

	Add some generic fallback characters.

	* tmac/fallbacks.tmac: New file.
	* tmac/troffrc: Include it.
	* tmac/Makefile.sub (NORMALFILES): Include it.

2012-05-20  Deri James  <deri@chuzzlewit.demon.co.uk>

	* doc/groff.texinfo: Add extra info about `.asciify'.
	Document new gropdf options -u and -s.

	* src/devices/gropdf/gropdf.man: Remove references to Type 42 fonts,
	they do not work in PDFs.
	Document new option -s which adds `statistics' line to end of PDF
	file showing number of pages in document.  This has always been the
	default behaviour (to add this line), all other software seems to
	ignore it as intended, but `gs' sometimes complains, so the default
	is now to omit the statistics.
	Document new option -u[cmapfilename] to allow a user ToUnicode CMap
	instead of gropdf's default.  If no `cmapfilename' given then do not
	include any ToUnicode CMap.

	* src/devices/gropdf/gropdf.pl <top>: Allow `bundled' flags on
	command line (i.e. -de = -d -e).
	Use $RT_SEP as multi path separator, not hard coded `:'.  Update all
	users.
	New flags -u and -s.
	Once a custom papersize has been set as \X'papersize x,y' make it
	sticky so all following pages use custom size.
	When importing pdf with \X'pdf: pdfpic ...' do not compress objects
	which are already compressed!  This caused problems with PDFs
	created with ImageMagick, now fixed.
	(IsText, PutLine, do_t): The troff `u' command can contain a kerning
	adjustment number, this was not being handled, now fixed.
	(do_c): The troff `c' command was not being handled correctly, now
	fixed.
	(FindChar, RemapChr, do_N): Handle fonts with more than 255 glyphs.
	($ucmap): Define CMap ToUnicode to convert ligatures
	(fl,fi,ff,ffl,ffi) back to individual characters, useful for
	cut'n'paste and text searching.
	(LoadFont): Handle it.
	(ToPoints, GetPoints): Handle `z' unit.
	(do_x, FixPDFColour, PutHotSpot): Allow Annotation colour to be
	groff colour, i.e. 0-65535 *3, or #rrggbb, or #rrrrbbbbgggg.
	(do_p):The papersize width/length in switch -p were reversed,
	corrected.

	* src/devices/gropdf/Makefile.sub (gropdf): Use $RT_SEP.
	Use $fontpath rather than $fontdir (this ensures site-font is
	included in searches).

	* tmac/pdf.tmac (PDFBOOKMARK.VIEW, PDFHREF.VIEW, PDFPAGE.Y): Fix
	strings.
	(pdfbookmark): Correct handling of bookmark levels.
	Convert \[em] to hyphen in bookmarks
	Rather use -N than -T for "named" bookmarks (-T already used for "tag"
	in pdfmark.tmac)
	(.pdfclean): New macro which attempts to asciify bookmark text.
	(.pdfpagename): New wrapper macro for \X'pdf: pagename'.
	(.pdfswitchtopage): New wrapper macro for \X'pdf: switchtopage'.

2012-03-10  Werner LEMBERG  <wl@gnu.org>

	Fix compiler warnings.

	* src/preproc/html/pre-html.cpp (alterDeviceTo): Avoid ambiguous
	if-else clause.

	* src/preproc/grn/main.cpp (sccsid): Comment out.

	* src/roff/troff/number.cpp (parse_expr) <case '*'>: Add cast.

	* src/devices/xditview/Makefile.sub (EXTRA_CFLAGS): Add `-Dlint' so
	that unused static ID arrays don't cause a warning.

	(Some) problems reported by Bjarni Ingi Gislason
	<bjarniig@rhi.hi.is>.

2012-03-05  Werner LEMBERG  <wl@gnu.org>

	* tmac/an-ext.tmac (SY): Handle argument with spaces correctly.

	Problem reported by Bjarni Ingi Gislason <bjarniig@rhi.hi.is>.

2012-03-01  Bjarni Ingi Gislason  <bjarniig@rhi.hi.is>

	[an-old] Fix warnings.

	* tmac/an-old.tmac (an-init): Insert missing braces.

2012-02-26  Werner LEMBERG  <wl@gnu.org>

	Update configuration files from `gnulib' and `config' repositories.

	This also fixes a problem with `iconv' on Solaris 10, as reported in

	  http://lists.gnu.org/archive/html/bug-groff/2012-02/msg00007.html

	* configure.ac: Call `gl_LOCALCHARSET.
	Call `AM_ICONV' as C++.

	* config.guess, config.rpath, config.sub, install-sh, mkinstalldirs:
	Updated.

	m4/lib-link.m4, m4/lib-prefix.m4: Updated.
	* m4/fcntl-o.m4, m4/localcharset.m4: New files.

	* Makefile.in: Updated.

	* src/include/localcharset.h, src/libs/libgroff/config.charset,
	src/libs/libgroff/localcharset.c: Updated.

	* aclocal.m4, configure, src/include/config.hin: Regenerated.

2012-02-20  Werner LEMBERG  <wl@gnu.org>

	Update `gnulib' files.

	The invocation was

	  gnulib-tool --add-import \
	              --dir=src/libs/gnulib \
	              wcwidth

	Additionally, src/libs/gnulib/configure.ac was adjusted from a
	`test' run as described in the change from 2010-12-13.

	* src/libs/gnulib/*: Updated.

2012-02-15  Deri James  <deri@chuzzlewit.demon.co.uk>

	[gropdf] Fixes and omissions.

	* src/devices/gropdf/gropdf.pl (<top>, do_u): Add facility to handle
	track kerning (.tkf).
	(do_x, do_p, do_t): If pages are reordered using `pagename' and
	`switchtopage' keep track of outline bookmarks.
	(do_x): Handle multiple files on gropdf command line, stitch
	multiple groff_out files together.  In the main read loop any argc
	values not consumed by options are taken as input files and
	processed in order.  What prevented it working properly before is
	the way an `x i' (initialize) record has been handled.  It now
	processes the initialization code only in the first file.
	(PutHotSpot): Allow user to control size of hotspot bounding box on
	clickable links by setting PDFHREF.LEADING

	* tmac/pdf.tmac (PDFHREF.LEADING): Adjust value.
	(pdf*href): Pass value of PDFHREF.LEADING to gropdf.

2012-02-10  Deri James  <deri@chuzzlewit.demon.co.uk>

2012-02-08  Werner LEMBERG  <wl@gnu.org>

	* src/preproc/pic/main.cpp (do_file): Check for invalid characters.

	Problem reported by Doug McIlroy <doug@cs.dartmouth.edu>.

	[mdoc] * tmac/doc-syms: Fix meaning of XBD acronym.

2012-01-25  Tadziu Hoffmann  <hoffmann@usm.uni-muenchen.de>

	* tmac/e.tmac (bl): Make it work inside blocks.

	See threads starting with

	  http://lists.gnu.org/archive/html/groff/2011-12/msg00055.html
	  http://lists.gnu.org/archive/html/groff/2012-01/msg00000.html

2012-01-10  Bruno Haible  <bruno@clisp.org>

	Fix handling of MAKEFLAGS variable.

	* Makefile.in (MAKE_K_FLAGS): Improved definition,
	as explained and discussed in

	  http://lists.gnu.org/archive/html/groff/2012-01/msg00039.html

2012-01-03  Ingo Schwarze  <schwarze@usta.de>

	Improve parallel builds.

	Some hdtbl and mom examples want PostScript formatting which
	requires the `DESC' file to be ready; however, the top-level
	`Makefile.in' doesn't currently enforce the proper order of building
	of `font/dev' before `contrib/hdtbl', `contrib/mom', and so on.

	Given that `font/dev' and the contrib examples are in different
	child processes of the recursive make system, it doesn't seem
	possible to solve this using clean Makefile dependencies.  We now
	enforce the order by splitting the shell command invoking recursive
	make in the top level `Makefile.in'.

	* Makefile.in (ALLDIRS): Remove `OTHERDIRS'.
	(dodirs): Updated.
	(`$(TARGETS)'): Handle `OTHERDIRS' separately.

2012-01-03  Kristaps Dzonsons  <kristaps@bsd.lv>

	[mdoc] Add `-isoC-2011'.

	* tmac/doc-syms (doc-str-St--isoC-2011): Add it.
	* tmac/groff_mdoc.man: Document it.

2011-12-26  Deri James  <deri@chuzzlewit.demon.co.uk>

	* font/devpdf/Makefile.sub: Only build fonts on first `make'.

	* doc/groff.texinfo (.tl): Improve documentation.
	Wording suggested by Keith Marshall
	<keithmarshall@users.sourceforge.net>.

2011-12-01  Werner LEMBERG  <wl@gnu.org>

	[me] Fix behaviour of centered block.
	Problem and possible fix reported in thread starting at

	  http://lists.gnu.org/archive/html/groff/2011-11/msg00002.html

	* tmac/e.tmac (`(c'): Always start with a new line.

2011-12-01  Ingo Schwarze  <schwarze@usta.de>

	[man] Print volume headers like mdoc.

	* tmac/an-old.tmac (an-init): Add default volume name if fifth
	argument to `.TH' is missing.

2011-11-22  Werner LEMBERG  <wl@gnu.org>

	* tmac/groff_man.man: Minor documentation improvements.

	char' for all members.

	* src/devices/grohtml/html-text.cpp (html_text::remove_def): Remove
	unused variable `q'.
	* src/devices/grohtml/post-html.cpp
	(html_printer::lookahead_for_tables): Remove unused variable `left'
	and `seen_text'.

2011-10-23  Ingo Schwarze  <schwarze@openbsd.org>

	[mdoc] Synchronize string tables with the mandoc(1) utility.

	* tmac/doc-common: Add many architecture names used in NetBSD and
	OpenBSD (and "arm" from FreeBSD) and remove the duplicate OS version
	entry for Darwin-10.6.0.

	* tmac/doc-syms: Add many library names used in NetBSD and FreeBSD.

	* tmac/groff_mdoc.man: Document all supported architecture names, OS

	install 'util/BuildFoundries', only used in 'make'.

	* src/devices/gropdf/gropdf.pl (<top>, GetType1): Make STDOUT and
	any font files read to be accessed in binary rather than text mode.
	Prevents errors when running on systems set up for UTF-8.

2011-08-10  Deri James  <deri@chuzzlewit.demon.co.uk>

	* src/devices/gropdf/gropdf.pl: Change command line option `-fy' to
	`-y' for consistency.

	* doc/groff.texinfo, src/devices/gropdf/gropdf.man: Updated.

	* font/devpdf/Foundry: Renamed to...

2011-07-12  Ted Harding  <ted.harding@wlandres.net>
	    Werner LEMBERG  <wl@gnu.org>

2011-07-03  Ben Laurie  <benl@FreeBSD.org>

	Fix clang warnings.

	* src/libs/libdriver/input.cpp (odd): Use parentheses.

	* src/roff/troff/mtsm.cpp (state_set::is_in): Fix parentheses;
	previous code always tested for bit 0.

2011-07-03  Guillem Jover  <guillem@debian.org>

	mdoc: Update more OS versions strings.

	* tmac/doc-common: Add versions strings for NetBSD, OpenBSD,
	FreeBSD, and DragonFly.

2011-04-08  Michail Vidiassov  <master@iaas.msu.ru>

2011-03-29  Ingo Schwarze  <schwarze@usta.de>

	Add another POSIX standard.

	* tmac/doc-syms: Add POSIX 1003.1b.

2011-03-29  Christian Weisgerber  <naddy@mips.inka.de>

	Fix build with non-GNU make.

	* Makefile.in ($TARGETS): We must not pass `$MDEFINES' recursively
	down to the sub-makes started in src/libs/gnulib, because that
	directory has its own values for `$top_srcdir' etc., and overriding
	those from the command line will cause the build to fail.
	Currently, `$MAKEOVERRIDES' will prevent the recursive passing of
	those overrides with GNU make, but not with other make(1)
	implementations.  It looks like all targets that require `$MDEFINES'
	set them explicitly anyway, so we shouldn't need to set `$MDEFINES'
	on the top level.

	Documentation updates.

	* NEWS, PROBLEMS, MANIFEST: Update.

2010-12-26  Werner LEMBERG  <wl@gnu.org>

	Speed up troff.

	* src/include/ptable.h (PTABLE): Make hash tables much more sparse
	by changing the ratio `FULL_NUM/FULL_DEN' from 2/3 to 1/4.  This
	increases the allocated memory by about 200kByte (which is nothing
	today) but assures that there aren't extremely long searches for a
	free hash slot in case that the hash function doesn't return a free
	one.  Due to the nature of the entries in uniuni.cpp, the used hash
	function in ptable.cpp is not optimal, but using a sparse array
	compensates this.

2010-12-20  Werner LEMBERG  <wl@gnu.org>

	Replace patch from 2010-12-18 with a much faster implementation.

	* src/roff/troff/node.h (node): Add virtual function
	`get_break_code'.

	* src/roff/troff/node.cpp (inter_char_space_node): Remove class
	completely.
	(glyph_node::merge_glyph_node): Restore previous version.

	(break_char_node): Add `prev_break_code' field and update
	constructors.
	(node::get_break_code, break_char_node::get_break_code): Implement.

	(node::add_char): Pass remaining cflags values.

	(break_char_node::add_self): Use the logic of the now deleted
	`inter_char_space_node::add_self' function to insert a space node if
	necessary.

2010-12-20  Daiki Ueno  <ueno@unixuser.org>

	A new try to not changing srcdir if building in separate builddir.

	Makefile.in ($GNULIBDIRS): Disable calls to autoconf and friends.

2010-12-20  Werner LEMBERG  <wl@gnu.org>

	Speed up access to cflags values.

	We now recompute the cflags values for all charinfo objects if
	`.class' has been called.

	* src/roff/troff/charinfo.h: Add external references to `class_flag'
	and `get_flags'.
	(charinfo): `get_flags' no longer has a return value.
	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
	charinfo::can_break_before, charinfo::can_break_after,
	charinfo::can_break_after, charinfo::ends_sentence,
	charinfo::transparent,, charinfo:ignore_hcodes,
	charinfo::prohibit_break_before, charinfo::prohibit_break_after,
	charinfo::inter_char_space): Call global `get_flags' only if
	necessary.
	(charinfo::add_to_class): Set `class_flag'.

	* src/roff/troff/input.cpp (class_flag): New global flag.
	(charinfo::charinfo): Call `get_flags' member function.
	(get_flags): New global function which iterates over all entries in
	the charinfo dictionary.
	(charinfo::get_flags): Set `flags' directly.

2010-12-19  Werner LEMBERG  <wl@gnu.org>

	Protect `.class' against cyclic nesting.

	* src/roff/troff/charinfo.h (charinfo::contains): Add optional
	boolean argument.
	* src/roff/troff/input.cpp (define_class, charinfo::contains): Check
	for cyclic nesting.

2010-12-18  Werner LEMBERG  <wl@gnu.org>

	Improve CJK support with new values for `.cflags'.

	This patch introduces three new values to `.cflags':

	  don't break before character: 128
	  don't break after character:  256
	  allow inter-character break:  512

	They are handled differently if compared to other cflags values:

	  (1) hcode values are completely ignored
	  (2) similar to kern values, and contrary to the other cflags
	      values, troff looks at pairs of characters to decide whether a
	      break gets inserted

	A yet-to-be-written patch should add inter-character spacing if
	those flags are active; currently, only zero-width breakpoints are
	inserted.

	* src/roff/troff/charinfo.h (charinfo): Change type of `flags' to
	`int'.  Update callers accordingly.
	New enum values `DONT_BREAK_BEFORE', `DONT_BREAK_AFTER', and
	`INTER_CHAR_SPACE'.
	New member functions `prohibit_break_before',
	`prohibit_break_after', and `inter_char_space'.
	* src/roff/troff/input.cpp: Updated.

	* src/roff/troff/node.cpp (inter_char_space_node): New class similar
	to kern_pair_node, collecting charinfo entities with the
	abovementioned cflags values.
	(break_char_type): Add new enum values.
	(glyph_node::merge_glyph_node): Handle abovementioned cflags values
	and emit an `inter_char_space_node' if necessary.

	* tmac/ja.tmac: Use new cflags values.

	* doc/groff.texinfo, NEWS, man/groff_diff.man: Document new values.

2010-12-18  Werner LEMBERG  <wl@gnu.org>

	Remove compiler warning.

	* src/libs/libgroff/relocate.cpp (msw2posixpath): Remove redundant
	dereferencing.

2010-12-16  Daiki Ueno  <ueno@unixuser.org>

	Don't change srcdir if building in a separate builddir.

	* Makefile.in ($GNULIBDIRS): Copy configuring stuff of gnulib if
	necessary.

	This issue happens with gcc 4.2.4.

	* src/roff/troff/node.cpp (node::~node): Move to...

	member function is publicly visible.

2010-12-15  Werner LEMBERG  <wl@gnu.org>

2010-12-13  Daiki Ueno  <ueno@unixuser.org>
	    Werner LEMBERG  <wl@gnu.org>

	Add wide character support to grotty.

	This is a huge patch, mainly by adding the gnulib infrastructure in
	a separate directory tree (in `src/libs/gnulib/lib') for its
	`wcwidth' module.  However, the actual changes to native groff
	source files are just a few lines.

	* Makefile.comm (INCLUDES): Updated.
	(LIBGNU): Define.

	* Makefile.in (NOMAKEDIRS): Updated.
	(GNULLIBDIRS): Define.
	(DISTDIRS): Add GNULLIBDIRS.
	($LIBDIRS): Depend on GNULLIBDIRS.

	  . Call

	      gnulib-tool --create-testdir \
	                  --dir=src/libs/gnulib \
	                  wcwidth

	    to get a testbed.

	  . Manually move directories src/libs/gl{lib,m4} to
	    src/libs/{lib,m4}, and do s/gllib/lib/ and s/glm4/m4/ everywhere
	    to `convert' the gnulib testbed to a standard gnulib
	    configuration as maintained by gnulib-tool.

	  . Call

	      gnulib-tool --add-import \
	                  --dir=src/libs/gnulib \
	                  wcwidth

	    to update everything.

2010-12-13  Werner LEMBERG  <wl@gnu.org>

	`.class' must not emit empty lines.

	* src/roff/troff/input.cpp (define_class): Add missing `skip_line'

	* src/libs/libgroff/font.cpp (glyph_to_unicode): Implement it.
	(font::contains, font::get_code): Use it.

	(charinfo): New members `ranges' and `nested_classes'.
	New member functions `get_unicode_code' and `get_flags'.
	New member functions `add_to_class', `is_class', and `contains'.
	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
	charinfo::can_break_before, charinfo::can_break_after,
	charinfo::can_break_after, charinfo::ends_sentence,
	charinfo::transparent,, charinfo:ignore_hcodes): Use `get_flags',
	which handles character classes also.

	* src/roff/troff/input.cpp (char_class_dictionary): New global
	variable.

	[troff]: Fix hyphenation problem with kerned letters.
	Problem reported by Steve Izma <sizma@golden.net>.

	* src/roff/troff/node.cpp
	(kern_pair_node::add_discretionary_hyphen): Compute `tf' using the
	first node, `n1'.  `n2' might be another kerning node, and the
	`get_tfont' member function isn't defined then.

2009-09-01  Michael Cain  <mcain6925@comcast.net>

	[pic] Fix a border case for arc computation.

	* src/preproc/pic/object.cpp (object_spec::make_arc): It can happen
	that test `radius < d' in the loop is satisfied, but the difference
	in the two values is on the order of 1e-10.  If `radius' is small,
	doubling the value can lead to a fairly gross error.

	The original code appears to have been intended to deal with the
	situation when radius is orders of magnitude less than `d'.  The
	replacement code simply assigns `radius' the smallest value that
	avoids problems with the floating point code further on in the
	routine.

2009-08-14  Roger Leigh  <rleigh@debian.org>

	* src/preproc/pic/pic.y: Split `expr' into `expr_lower_than' and
	`expr_not_lower_than' so that we can handle

	  (1/3)<(1/2)<foo,bar>,baz>

	correctly.  Without the patch, `(1/3)<(1/2)' is handled prematurely
	as a comparison.

	* configure.ac: Read `VERSION' and `REVISION' files to provide
	proper values for AC_INIT.
	* Makefile.in: Use `@datarootdir@' and `@docdir@' so that

	* doc/groff.texinfo: Improve documentation of `lsm' request.

2009-02-14  Werner LEMBERG  <wl@gnu.org>

	Implement a leading spaces macro request, `lsm', in analogy to
	`blm'.
	Implement two new number registers, \n[lsn] and \n[lss], which hold
	the number of spaces and the horizontal space, respectively, which
	would be inserted if the macro registered by `lsm' wasn't called.
