        * tmac/an-old.tmac: Use `de1' instead of `de' request for all
        public and trap-invoked macros.  As a consequence, the man macros
        work in compatibility mode also.

        Updated documentation.

        When inside displays, an empty input line warning should be

        warning to be emitted.

        Fix indentation in SYNOPSIS.

        Updated to include changes of latest BSD mdoc version (basically,
        the only change is that `.Fn' and `.Fc' put a final semicolon after
        a function declaration in the SYNOPSIS section).

        functions.
        (doc-indent-synopsis-active): New register.
        (Nd, Fn, Fo): Use it.
        (Cd): It requires manipulation of \n[doc-indent-synopsis] so that
        `.Cd' with long argument line produces indented wrapped lines.
        Also, the misplaced `.nop \*[doc-Nm-font]\c'' caused extra
        undesirable line break to be output.
        (doc-do-func-decl, Nm, Vt, Fn, Fo): Remove extraneous calls to
        `.rs'.
        (Fn, Fc): Add final `;' to output.

        Fixed grohtml handling of any named glyph for glyph indexes < 0x80.
        Cosmetic changes to `.html-begin', `.html-end', `.html-image' which

        * tmac/groff_tmac.man: Fix typo.

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.

        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.
        * src/roff/troff/node.h (unbreakable_space_node, hmotion_node,
        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.

        * src/roff/troff/div.h (diversion): Add `saved_prev_line_interrupted'.
        * src/roff/troff/div.cc (do_divert): Use it.

2001-01-25  Werner LEMBERG  <wl@gnu.org>

        Adding the `linetabs' request.  If set, tab distances are not
        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.

        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.

2001-01-23  Werner LEMBERG  <wl@gnu.org>

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

        * src/roff/troff/div.h (diversion): Add `saved_saved_indent' and
        `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.

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.

        * tmac/Makefile.sub: Added `wrap' stuff again, but installing into
        $(systemtmacdir) since the wrapper files are platform-dependent.

        * src/roff/troff/input.cc: Introduce MACRO_POSTFIX.
        (open_mac_file, macro_source): Implement it.

        $GROFF_BIN_PATH.
        * src/roff/groff/groff.cc (main): Implement $GROFF_BIN_PATH and
        $GROFF_PATH__ (the latter for communication with troff).
        * src/roff/troff/input.cc (main): Use $GROFF_PATH__ for $PATH if
        set.
        * NEWS, src/roff/nroff/nroff.man, src/roff/groff/groff.man,

        output_pending_lines() instead of output_line().
        * src/preproc/eqn/main.cc (do_file): Fix graphic_end().

        Replace tmac.safer with a real secure solution.

        system_request, pipe_output): Disable requests if in safer mode.
        * src/roff/groff/groff.cc (main): Remove reference to tmac.safer.
        * tmac/tmac.safer, tmac/groff_msafer.man: Removed.
        * tmac/Makefile.sub, NEWS, man/roff.man, tmac/groff_tmac.man,

        src/roff/troff/troff.man, arch/djgpp/README: Updated.

        * src/devices/grops/ps.cc (main), src/devices/grops/psrm.cc

2000-10-09  Werner LEMBERG  <wl@gnu.org>

        * src/libs/libbib/map.c, src/libs/libgroff/getcwd.c,
        src/libs/libgroff/strtol.c, src/preproc/html2/image.cc,
        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
        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>

        Adding a new escape sequence \B'...': If the string between
        the delimiters is a valid numeric expression, return the character
        `1', and `0' otherwise.  This is an analogon to \A.

        * src/roff/troff/input.cc (do_expr_test): Implement it.
        (token::next): Use it.
        * src/roff/troff/troff.man, NEWS, man/groff.man: Document it.

        * tmac/tmac.trace: Made independent from escape character.

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
        character.  These two requests are needed to make tmac.trace
        independent from the escape character (which might even be
        disabled).

        * src/roff/troff/input.cc (save_escape_char, restore_escape_char):
        Implement it.
        (init_input_requests): Use it.

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

2000-09-22  Ricardo Soares Guimarães  <ricardo@conectiva.com.br>

        Adding a new option -P and new environment variable GROPS_PROLOGUE
        to grops, selecting a different prologue file (minor modifications
        by WL).

        * src/devices/grops/psrm.cc (resource_manager::output_prolog),
        src/devices/grops/ps.cc (main): Implement it.
        * src/devices/grops/grops.man, NEWS: Document it.

2000-09-22  Werner LEMBERG  <wl@gnu.org>

        * INSTALL: Add info about selecting paper format.

2000-09-21  Werner LEMBERG  <wl@gnu.org>

        * src/roff/troff/input.cc (main): Fixing compiler warning.
        * src/include/{driver.h, lib.h}: Move inclusion of string.h and
        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.

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

        * tmac/groff_mdoc.samples.man: Small fixes.

2000-09-08  Werner LEMBERG  <wl@gnu.org>

        * tmac/groff_mdoc.man: Fixing typo.

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>

        * doc/groff.texinfo: Added some comments.

2000-08-30  Werner LEMBERG  <wl@gnu.org>

        * src/roff/troff/TODO: Updated.

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

        * doc/groff.texinfo: Fix comment how to compile the DVI file.

2000-08-25  Eli Zaretskii  <eliz@is.elta.co.il>

        * 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>

        * NEWS, doc/groff.texinfo, tmac/groff_tmac.man, man/roff.man,
        src/roff/troff/troff.man: Document Eli's latest changes.

2000-08-25  Eli Zaretskii  <eliz@is.elta.co.il>

        * src/roff/troff/input.cc (open_mac_file, macro_source): Support
        macro file names of the form NAME.tmac as well as tmac.NAME.

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

        * src/include/posix.h: Remove definition of FILENAME_MAX.

        * src/preproc/html2/pre-html.h, pre-html.cc: Add return type to
        `sys_fatal' and `stop' function().

        * 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.
        * src/roff/troff/node.h, src/roff/troff/node.cc
        (troff_output_file::really_print_line,
        ascii_output_file::really_print_line,
        supress_output_file::really_print_line): Use `width' parameter.
        (troff_output_file::really_on, troff_output_file::really_off,
        output_file::on, output_file::off, real_output_file::on,
        real_output_file::off, real_output_file::really_on,
        real_output_file::really_off): New functions.
        (real_output_file:public output_file): New variable `output_on'.
        (real_output_file::begin_page, real_output_file::copy_file,
        real_output_file::transparent_char, real_output_file::print_line):
        Use it.
        (real_output_file::print_line): Use check_output_limits.
        * src/roff/troff/reg.h, src/roff/troff/request.h,
        src/roff/troff/input.cc (assign_registers): New function to remove
        two `goto's.
        (do_ps_file): Use it.
        (check_output_limits, reset_output_registers, output_request,
        init_output_requests): New functions.
        (init_input_requests): Updated.

        Added new grohtml2 device and html2 preprocessor (coding
        not yet finished) which will eventually replace grohtml.

        * Makefile.in, tmac/Makefile.sub, tmac/eqnrc, tmac/troffrc-end:
        Updated.
        * src/include/htmlindicate.h, src/include/htmlindicate
        (html_begin_suppress, html_end_suppress): New functions.
        * src/preproc/tbl/main.cc: Use it.
        * src/roff/groff/groff.cc: Add support for html2 device (which will
        automatically invoke the html2 preprocessor).
        * src/roff/troff/input.cc (is_html2): New variable.
        * src/roff/troff/troff.h, src/roff/troff/env.h,
        src/roff/troff/env.cc (environment::add_html_tag): New function
        (uses `is_html2').
        (environment::do_break): Use it.
        * font/devhtml2/*: New files.
        * src/devices/grohtml2: New device.
        * src/preproc/html2: New preprocessor.
        * tmac/tmac.html-tags, tmac/tmac.html2: New files.

        groff-getopt.h.

2000-08-18  Werner LEMBERG  <wl@gnu.org>

        * configure.in: Don't provide an empty value for SH_SCRIPT_SED_CMD
        since some non-GNU sed programs can't handle null regexps.

        src/roff/grog/Makefile.sub, src/roff/nroff/Makefile.sub: Updated.

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

        * tmac/tmac.a4: Will now work with ms macros also; -ma4 should be
        used before -ms.

        * tmac/tmac.man.old: Remove unused number register.

        * tmac.doc: Minor documentation fix.

2000-08-07  Paul Eggert  <eggert@twinsun.com>

        * src/roff/groff/pipeline.c (is_system_shell):

        that the argument length is less than FILENAME_MAX.
        * src/libs/libgroff/tmpfile.cc (add_tmp_file): Likewise.
        Use struct hack to allocate and free file name.
        (struct xtmpfile_list): fname is now part of the structure,
        not a pointer to another string.

2000-08-07  Tom Schmidt  <tschmidt@micron.com>

        * 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.
