2002-02-04  Larry Kollar  <kollar@alltel.net>

	compatibility mode is saved on entry, switched off during string
	expansion, and restored on exit.  The latter is the pendant to `dei'
	for `am'.

	Insert COMPATIBLE_SAVE and COMPATIBLE_RESTORE at the beginning and
	end of string, respectively.

	* tmac/trace.tmac: Trace calls to `am' also.  Make it work in
	compatibility mode.

	* NEWS: Revised.
	* doc/groff.texinfo: Introduce @Def...List, @Def...Item, and

	proper HTML output -- see the comment in the file for more
	information.
	Updated all calls.

2002-01-21  Werner LEMBERG  <wl@gnu.org>

	Complete revision of color support:

	  Adapt programs to the new libdriver/input.cc.

	  Color spaces are no longer converted to RGB but transferred as-is
	  in the troff intermediate output format.

	  Handle default color gracefully.  troff now supports a `default'
	  color (which can't be changed).

	  grops will now use the proper color space functions if available.

	  Update pic.

	Note that currently grohtml doesn't handle colors properly.  This
	has to be fixed.

	(ps_printer::set_line_thickness): Renamed to ...
	(ps_printer::set_line_thickness_and_color): This (and updated).
	(ps_printer::set_color): Change second parameter from `complete'
	to `fill' which better describes what it does.
	(ps_printer::draw): Call `flush_sbuf' to output graphic commands
	and text in the right order.
	Updated.
	Remove branches for `f' and `F'; this is handled by
	libdriver/input.cc.

	Implementing color support in troff, pic, grops, and grohtml.  These
	changes are based on a major patch provided by Gaius Mulley
	<gaius@glam.ac.uk>.

	New request: `defcolor', supporting rgb, cmy, cmyk, and gray
	definitions with both hex values and fractions.

	New escapes: \m and \M for drawing and background color,
	respectively.  This corresponds to the troff output commands `m'
	and `DF'.

	groff and troff accept command line switch `-c' to disable color
	output (which is automatically disabled in compatibility mode).

	New scaling indicator `f' for fractions (1f = 65536u).

	New conditional operator `m' to test for defined colors with `if'
	and `ie'.

	New keywords `color' (or `colour', `colored', `coloured'), `outline'
	(or `outlined'), and `shaded' added to pic.

	* src/include/color.h: New file.
	* src/include/driver.h: Include it.

2001-02-16  Werner LEMBERG  <wl@gnu.org>

	Fixing a bug which prevented proper end-of-sentence recognition
	between an `unformatted' box and the following text.  As a
	consequence, vertical line distances are no longer preserved in
	boxes after a call to `.unformat' -- because boxes aren't
	line-oriented (contrary to diversions), this doesn't make sense
	anyway.

	* src/roff/troff/node.cc (*node::set_unformat_flag): Add return
	value.
	(vertical_size_node::set_unformat_flag): New method.

	* src/roff/troff/troff.man, NEWS, man/groff.man: Improved
	documentation of `asciify' and `unformat' requests.

2001-02-13  Werner LEMBERG  <wl@gnu.org>

	Redesigned the `unformat' request.  It is no longer connected with
	`asciify' but rather uses new `reread()' methods if the `unformat'
	flag is set.  Additionally, the handling of space characters after
	unformatting has been fixed so that they retain their width.

	* src/roff/troff/node.h (width_list): New structure to store
	original widths of spaces.
	(node): Added `unformat' member.
	Replaced `num_spaces' variable with `orig_width' list.
	* src/roff/troff/node.cc (*node::asciify,
	asciify_reverse_node_list): Removed `unformat_only' flag and related
	code.
	(word_space_node::asciify, word_space_node::word_space_node): Use
	`orig_width'.
	(word_space_node::~word_space_node): New destructor.
	(word_space_node::copy): Updated to handle `orig_width'.
	(hmotion_node::copy, unbreakable_space_node::copy): Updated.
	(*node::merge_space): Update `orig_width' list if necessary.
	(*node::set_unformat_flag): New methods to set the `unformat' flag.
	* src/roff/troff/enc.cc (environment::space_newline): Use
	`width_list'.
	(environment::space): Added method to handle space width and
	sentence space width as parameters.  Use `width_list'.
	(environment::make_tab_node): Updated.
	* src/roff/troff/env.h: Updated.
	* src/roff/troff/input.cc (word_space_node::reread,
	unbreakable_space_node::reread, hmotion_node::reread): New methods
	to handle nodes specially if `unformat' flag is set.
	(do_asciify_macro): Renamed back to ...
	(asciify_macro): This.
	(unformat_macro): New implementation to simply set the `unformat'
	flag.

	* MORE.STUFF: Added more info about deroff.

2001-02-08  Werner LEMBERG  <wl@gnu.org>

	* src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
	space_char_hmotion_node, overstrike_node): Add `get_hyphen_list()'
	and `add_self()' methods to avoid hyphenation.  For example, the
	hyphen list for `foo\0\0bar' was `foobar', causing insertion of a
	soft hyphen after `foo'.  Now the hyphen list is correctly
	`foo<ignore><ignore>bar'.

2001-02-05  Yoshiteru Kageyama  <yt-kage@cb3.so-net.ne.jp>

	* tmac/groff_tmac.man: Fix `BIR' macro.

2001-02-04  Werner LEMBERG  <wl@gnu.org>

	method.
	(space_node): Add `was_escape_colon' member.  Add `is_escape_colon()'
	and `asciify()' methods.
	* src/roff/troff/node.cc (space_node::space_node): Updated.
	(space_node::asciify): Handle `was_escape_colon'.
	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

	Handle `\~' similar to other comparable requests.

	* src/roff/troff/input.cc (process_input_stack): Remove now obsolete
	label.
	(token::next): Move creation of an unbreakable_space_node to...
	(token::add_to_node_list): Here.

	Fix a bug which sometimes prevented hyphenation of words connected
	with `\~' or `\ ' (and other escape sequences handled as
	TOKEN_NODE).  This also fixes a hyphenation problem with boxes
	(after a call to the `unformat' request).

	* src/roff/troff/env.h (environment::possibly_break_line,
	environment::hyphenate_line): Introducing `start_here' parameter.
	* src/roff/troff/env.cc (environment::space_newline,
	environment::space): Use it.
	(environment::possibly_break_line, environment::hyphenate_line):
	Implement it.

	space_char_hmotion_node, overstrike_node): Add
	`get_hyphenation_type()' method.

	* src/roff/troff/env.cc (get_line_tabs): New function.
	(init_env_requests): Use it.
	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

	* VERSION, REVISION: Changing to 1.17.0.

2001-01-28  Werner LEMBERG  <wl@gnu.org>

	Fixed a bug which prevented hyphenation of words which are finished
	with `\)'.

	* src/roff/troff/token.h (token): Add enum type
	`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
	* src/roff/troff/input.cc (token::next, token::description,
	get_line_arg, token::add_to_node_list, token::process): Use it.

2001-01-27  Werner LEMBERG  <wl@gnu.org>

	computed relative to the input line but relative to the output line.

	* src/roff/troff/env.h (environment): New member `line_tabs'.
	* src/roff/troff/env.cc (line_tabs_request): Implement request.
	(environment::environment, environment::copy): Updated.

	(init_env_requests): Register request.
	* src/roff/troff/troff.man, man/groff.man, NEWS: Document it.  Other
	fixes.

2001-01-24  Werner LEMBERG  <wl@gnu.org>

	Introducing a new read-only register `.int' which is set to a
	positive value if the last output line is interrupted (i.e., if it
	contains `\c').

	* src/roff/troff/env.cc (init_env_requests): Add it.
	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

2001-01-23  Gaius Mulley  <gaius@glam.ac.uk>

	* node.cc (hmotion_node::copy, hmotion_node::asciify): Use it.

	Added new request `unformat' which will, contrary to `asciify',
	preserve font information after unformatting (i.e., only nodes
	dealing with horizontal space are converted back to input
	characters).

	* input.cc (asciify_macro): Renamed to ...
	(do_asciify_macro): this, having a new parameter `unformat_only'.
	(asciify_macro, unformat_macro): New; using do_asciify_macro.
	(init_input_requests): Added `unformat'.
	* node.cc (*_node::asciify), asciify_reverse_node_list: Added

	Stuff related to `html' has been renamed to `html-old' and `html2'
	stuff has been renamed to `html' (including directories).  The new
	html device driver is therefore invoked as `-Thtml'.

	Added new `\O' escape to suppress output (needed by html driver).

	Added functions and code to pass info about input-level commands
	(`.in', `.fl', etc.) to html driver.

	Three new functions (.html-begin, .html-end, and .html-image) for
	better html handling: `html-begin' will execute the remaining line
	if at the outermost nesting level, increasing an internal counter.
	`html-end' does the same but decreases the internal counter.
	`html_image' puts its arguments into a special node (suppress_node)
	to define an image region.

	The `output' request has been removed.

	src/preproc/html2/pre-html.cc, src/preproc/html2/pushbackbuffer.cc,
	src/roff/groff/pipeline.c: Removing `#ifndef errno' to avoid
	compilation errors with some compilers.  It seems that this code

	for that particular old-fashioned compiler.

	* MORE.STUFF: Added info about Meta-tbl.

	* doc/groff.texinfo: Added more info about `.if "..."..."'.

2000-10-07  Werner LEMBERG  <wl@gnu.org>

2000-10-06  Werner LEMBERG  <wl@gnu.org>

	Adding a new request .dei: define indirect.  The first and second
	parameter of .dei are taken from string registers instead directly;
	this very special request is needed to make tmac.trace independent
	from the escape character (which might even be disabled).

	* src/roff/troff/input.cc (do_define_macro): Implement it.
	(define_macro_indirect): New function.
	(init_input_requests): Use it.

	Adding two requests .ecs and .ecr: Save and restore the escape

	Implement it.
	(init_input_requests): Use it.

	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.

2000-09-22  Ricardo Soares Guimar�es  <ricardo@conectiva.com.br>

	Adding a new option -P and new environment variable GROPS_PROLOGUE

	strings.h from the former to the latter.
	* src/devices/grolbp/lpb.cc, src/include/lib.h: Move strncasecmp()
	stuff from the former to the latter.

2000-09-11  Werner LEMBERG  <wl@gnu.org>

	Implementing two new requests .tm1 and .tmc: The former is similar
	to .tm but can output leading spaces; its syntax is similar to
	defining a string, i.e., a `"' can be used to mark the beginning of
	the string to be written to stderr: `.tm1 " test'.  The latter is
	similar to .tm1 but doesn't write out a final newline character.

	* src/roff/troff/input.cc (terminal1, terminal_continue,
	do_terminal): New functions.
	(init_input_requests): Use them.
	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.

2000-09-02  Werner LEMBERG  <wl@gnu.org>

	Implementing a .nop request which does nothing.

	* src/roff/troff/input.cc (nop_request): New function.
	(init_input_requests): Use it.
	* src/roff/troff/troff.man, NEWS, man/groff.man: Updated.

2000-09-01  Werner LEMBERG  <wl@gnu.org>

	* font/devps/generate/Makefile (SHELL): Define explicitly to
	"/bin/sh", for non-Unix platforms.

	backslash (which doesn't work on DOS/Windows).
	
	* font/devlj4/generate/Makefile (extraclean): Ditto.

	* font/devdvi/generate/Makefile (extraclean): Ditto.

2000-08-25  Werner LEMBERG  <wl@gnu.org>

	still obeying motion) and also the opminx, opminy, opmaxx, opmaxy
	registers (for passing the output dimensions to the output device).

	* src/roff/troff/div.cc (top_level_diversion::output): Use `width'
	parameter.
	* src/roff/troff/node.h, src/roff/troff/node.cc

	since some non-GNU sed programs can't handle null regexps.
	* configure, src/preproc/eqn/Makefile.sub,
	src/roff/grog/Makefile.sub, src/roff/nroff/Makefile.sub: Updated.

	* src/devices/grolbp/lbp.cc: Add an AIX workaround for an autoconf
	bug (string.h and strings.h are both needed according to latest
	POSIX standard).

	* MORE.STUFF: Added info about unroff and troffcvt.

2000-08-08  Werner LEMBERG  <wl@gnu.org>

	* src/include/posix.h: Add a default value for FILENAME_MAX.

2000-08-06  Paul Eggert  <eggert@twinsun.com>

2000-02-06  Werner LEMBERG  <wl@gnu.org>

	I've considerably modified the directory structure of the
	distribution to get a more vertical layout.  For example, the number
	of top level directories has been reduced from 42 to 6.

	As a consequence, many changes, especially to the makefiles, were
	necessary:

	* The makefile variables `top_builddir' and `top_srcdir' have been
	introduced.  Virtually all relative paths have been replaced with
	absolute ones using these two variables.

	* Dependencies (in the files `Makefile.dep') are no longer part of
	the distribution.  Instead, they are created during a `make install'
	in the build directory.

	* aclocal.m4 (GROFF_SRCDIR, GROFF_BUILDDIR): Two new functions to
	make `top_srcdir' and `top_builddir' absolute.

	Some other changes:

	* Man pages now depend on the files `VERSION' and `REVISION'.

	* The added shell script `mkinstalldirs' will replace `mkdir' in
	almost all cases.

	* VERSION: Version number increased to 1.16.

2000-02-04  Werner LEMBERG  <wl@gnu.org>

	* grops/psrm.cc (read_one_of): Fixed pointer incrementation.

	* Makefile.in: Removed $(tmac_m) since it is no longer needed
	(after an update of the mm stuff).

	* troff/Makefile.sub (majorminor.cc): Fix dependencies.

2000-02-03  Werner LEMBERG  <wl@gnu.org>

	The .psbb request will now also accept Mac PS images (i.e. using LF
	as the EOL character).

	* troff/input.cc (ps_get_line): New function, taken from psrm.cc
	(with slight modifications).
	* troff/input.cc (do_ps_file): Use it.

	* test-groff: Add grohtml and grolj4 output devices to PATH.

2000-01-30  Werner LEMBERG  <wl@gnu.org>

	* NEWS, MORE.STUFF: Updated.

2000-01-30  Cary D. Renzema  <caryr@dollar.mxim.com>

	Add the `srand' command to pic.

	* pic/lex.cc, pic/pic.y: Implement it.
	* pic/pic.man: Document it.
	* pic/pic.cc, pic/pic.tab.h: Regenerated (with yacc).

2000-01-30  Werner LEMBERG  <wl@gnu.org>

	Add a new request `.psbb'.  This does exactly what the external
	program psbb did.  It scans a PostScript image file for a
	%%BoundingBox comment and extracts the bounding box values (in
	PostScript units) which	are then stored in the four new (read-only)
	number registers `llx', `lly', `urx', and `ury'.

	This will allow the usage of the .PSPIC macro without worrying
	about unsafe behaviour of groff, i.e., it will work without the
	`-U' switch of groff.

	* troff/input.cc: Implement it.
	* tmac/tmac.pspic: Use it.
	* troff/troff.man, grops/grops.man, NEWS: Document it.
	* psbb/*, Makefile.in: Remove it since it is no longer needed.

	This is bloody C code simply adapted from psbb.c!  Any improvements
	welcome.

	The macros .URL, .FTP, and .MAILTO now accept a third argument which
	will be immediately appended to the second argument (to be used with
	punctuation, for example).

	Disabled .CDFTP macro temporarily for security reasons.

	* tmac/groff_markup.man: Complete revision for latest changes in
	tmac.arkup -- note that it does not yet format correctly with
	grohtml :-(

	SUPPRESS_BOTTOM_REG to 1, spring the trap, then set
	SUPPRESS_BOTTOM_REG back to 0.  In T#, do nothing if
	SUPPRESS_BOTTOM_REG is non-zero.  In T#, always mark the current
	vertical position and return to it before turning traps on again.

	ps/ps.c (ps_printer::draw), dvi/dvi.c (dvi_printer::draw): Make
	type of first argument int rather than char.  This works around a
	bug on the 68030 based Apollo using g++ 1.37.1.

	* lib/font.c: Initialize font::hor and font::vert to 1.
	(font::load_desc): Check the values of font::hor and font::vert.

	* lib/lib.h: Added definition of INT_DIGITS. Fix it so that it can
	be included in a C compilation.
	(iftoa): Use INT_DIGITS. Include lib.h.
	(itoa): Likewise.
	(as_string): Likewise.
	* tbl/table.c: Removed definition of INT_DIGITS.

	argument to \w is at a different input level.

	* tbl/table.c (table::init_output): Define a new macro
	REPEATED_VPT_MACRO, like vpt but if in a diversion also
	transparently outputs itself.

	REPEATED_MARK_MACRO, like mk but if in a diversion also
	transparently outputs itself.
	(table::do_row): Mark row_top_reg using	REPEATED_MARK_MACRO. This
	is necessary because .TH might not call .T#.
	(table::do_top): Likewise TOP_REG.
	(table::define_bottom_macro): If TOP_REG is no longer valid, use
	#T - DOUBLE_LINE_SEP rather than #T. This is necessary because the
	table header might contain just the two top rules.

	do_break() but before setting exit_flag to 2.

	* troff/input.c: Remove FLUSH_PENDING_LINES and
	TOKEN_FLUSH_PENDING_LINES. Instead, flush pending lines from
	environment after END_TRAP token seen, but only if there aren't
	any more traps still unfinished.

	* troff/env.c (environment::hyphenate_line): Don't completely give
	up if the word is not to be hyphenated; continue so that breaks
	can be made at break_char_node's.

	* lib/lib.h: Only define INT_MAX if it's not already defined;
	undef INT_MIN if it's already defined.

	* Makefile: Make it easy to define CFRONT_ANSI_BUG.
