Version 1.21 released
=====================

	* NEWS, REVISION, VERSION, doc/groff.texinfo, doc/webpage.ms:
	Updated.
	* aclocal.m4, configure: Regenerated.

2010-12-31  Werner LEMBERG  <wl@gnu.org>

	* doc/webpage.ms: Updated.

2010-12-30  Werner LEMBERG  <wl@gnu.org>

	Call texi2dvi with correct makeinfo binary.

	* doc/Makefile.in (.texinfo.dvi, .texinfo.pdf): Use $(MAKEINFO).

2010-12-30  Werner LEMBERG  <wl@gnu.org>

	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.

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

	Fix compilation problem.

	This issue happens with gcc 4.2.4.

	* src/roff/troff/node.cpp (node::~node): Move to...
	* src/roff/troff/node.h: Here.  This ensures that the inline
	member function is publicly visible.

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

	Remove unused code.

	* src/roff/troff/node.cpp, src/roff/troff/node.h
	(space_node::space_node): Remove unused constructor.

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

	Use enum to increase readability.

	* src/roff/troff/node.cpp (break_char_type): New enum.
	(break_char_node::add_self, node::add_char): Use it.

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.
	($LIBDIRS): Depend on GNULLIBDIRS.
	($GNULLIBDIRS): New target.

	* src/libs/libgroff/font.cpp (font::get_width, font::load)
	[is_unicode]: Use `wcwidth'.

	* src/roff/troff/Makefile.sub (XLIBS): Add LIBGNU.
	* src/roff/troff/input.cpp (main): Set LC_CTYPE.

	* src/devices/grotty/Makefile.sub (XLIBS): Add LIBGNU.
	* src/devices/grotty/tty.cpp (main): Set LC_CTYPE.

	* src/libs/gnulib/*: New files.  The import was done as follows:

	  . 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'
	calls.

	    Daiki Ueno  <ueno@unixuser.org>

	Implement support for character classes.

	This patch uses standard C++ headers, contrary to the rest of groff.
	Ideally, everything in groff should be updated to do the same.

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

	* src/roff/troff/charinfo.h: Include <vector> and <utility>.
	(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.
	(define_class): New function.
	(init_input_requests): Register `class'.

	[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.

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

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

	Improve configuration.

	* configure.ac: Read `VERSION' and `REVISION' files to provide
	proper values for AC_INIT.
	* Makefile.in: Use `@datarootdir@' and `@docdir@' so that
	configure's `--datarootdir' and `--docdir' options are honoured.
	Documentation is now by default installed into something like
	`/usr/local/share/doc/groff-1.20.1'.

	* configure: Regenerated.

	* 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.

	* src/roff/troff/input.cpp (leading_spaces_macro_name,
	leading_spaces_number, leading_spaces_space): New global
	variables.
