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/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>

	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.

	`TOKEN_TRANSPARENT_DUMMY' and method `transparent_dummy()'.
	* src/roff/troff/input.cc (token::next, token::description,

	* 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.

	* 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.

2001-01-15  Gaius Mulley  <gaius@glam.ac.uk>

	First cut of the new html device driver.  Changes to pre-html and
	the new grohtml are too numerous to be documented here.

	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
	is no longer necessary -- if yes, it is easy to add some #ifdef's

	* 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

	* 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

	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.

	* font/devps/generate/Makefile (SHELL): Define explicitly to
	"/bin/sh", for non-Unix platforms.
	(extraclean): Use a more portable "" quoting instead of a
	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>

	* test-groff: Updated.

2000-08-24  Gaius Mulley  <gaius@glam.ac.uk>

	Added the new troff command .output <arg> to suppress output (while
	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.

	(check_output_limits, reset_output_registers, output_request,
	init_output_requests): New functions.
	(init_input_requests): Updated.

	* Makefile.in, tmac/Makefile.sub, tmac/eqnrc, tmac/troffrc-end:
	Updated.

	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>

	Add support for new BSD-style man pages (with ".Dd" instead of
	".TH"), so that "groff -man" understands both styles, even
	when running "groff -man" on a host whose system man page
	macros don't support ".Dd".

	* tmac/Makefile.sub (NORMALFILES): Add tmac.an.old.
	(stamp-wrap): Source tmac.andoc first when wrapping man macros,
	in case the system man macros don't define Dd or TH.

	* tmac/tmac.an.old: Renamed from tmac/tmac.an.
	* tmac/tmac.an: New one-line file.
	* tmac/tmac.andoc (TH): Adjust to the tmac.an.old file renaming.
