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/node.hh: Updated.
	* src/roff/troff/input.cc (word_space_node::reread,
	hmotion_node::reread): Reset `unformat' flag after usage.
	(unformat_macro): Append only if `set_unformat_flag()' returns
	non-zero.
	* src/roff/troff/troff.man: Updated.

2001-02-15  Werner LEMBERG  <wl@gnu.org>

	* 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>

	A new escape sequence `\:', inserting a zero-width break point.

	* src/roff/troff/input.h: Adding `ESCAPE_COLON'.
	* src/roff/troff/input.cc (get_copy, token::next, asciify):
	Implement it.
	* src/roff/troff/node.h (node): Add `is_escape_colon()' virtual
	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.
	* src/roff/troff/input.cc (process_input_stack): Use it.

	space_char_hmotion_node, overstrike_node): Add
	`get_hyphenation_type()' method.
	* src/roff/troff/node.cc (break_char_node::asciify): Don't asciify
	if `unformat_only' is active.

2001-01-30  Werner LEMBERG  <wl@gnu.org>

	Implemented new read-only number register `.linetabs' which
	returns 1 if in line-tabs mode, 0 otherwise.

	* src/roff/troff/env.h (environment): Add get_line_tabs() member.
	* 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>

	* src/roff/troff/input.cc (asciify): Add ESCAPE_RIGHT_PARENTHESIS.

2001-01-25  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.
	(environment::distance_to_next_tab): Use `line_tabs'.
	(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>

	* tmac/mwww.tmac: Call `www.tmac', not `arkup.tmac'.
	* src/preproc/html/pre-html.cc (findPrefix): New function which
	generates the troff executable name via the system prefix.
	* src/preproc/eqn/main.cc: Modified warning message.

	troff's `box' and `boxa' requests didn't preserve temporary
	indentation.

	`saved_target_text_length' members.
	* src/roff/troff/div.cc (do_divert): Use them.

	Tabs (but not yet leaders and fields) are now handled correctly by
	`asciify' request.

	* node.h (hmotion_node): Add field `was_tab'.
	* env.cc (environment::make_tab_node): Set 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.
	(init_input_requests): Added `unformat'.
	* node.cc (*_node::asciify), asciify_reverse_node_list: Added
	parameter to control asciification process.
	* node.h (*_node::asciify): Ditto.
	* NEWS, src/roff/troff/troff.man, man/groff.man: Document it.

	* test-groff: Updated.

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.
