2004-04-06  Keith Marshall  <keith.d.marshall@ntlworld.com>

        Make scripts like nroff.sh and neqn.sh portable across various
        (Unix-like) shell implementations from Cygwin, MSYS, etc., which use
        non-POSIX path separators.  The idea is to extend those scripts to
        decide at run-time (of the script) which path separator to use.

        * arch/misc/Makefile.sub: New file.
        * arch/misc/shdeps.sh: New file, generating OS dependency fixups.
        This script handles @GROFF_BIN_PATH_SETUP@, replacing it with
        a proper definition of the variable `GROFF_RUNTIME'.

        * Makefile.in (SH_DEPS_SED_SCRIPT): New variable.
        (MDEFINES): Add SH_DEPS_SED_SCRIPT.
        (PROGDEPDIRS): New variable.
        `FORCE' it.
        (PROGDIRS): Add PROGDEPDIRS.

        * src/preproc/eqn/Makefile.sub (neqn): Call SH_DEPS_SED_SCRIPT.
        Don't substitute @SEP@ and @BINDIR@.
        * src/preproc/eqn/neqn.sh: Use @GROFF_BIN_PATH_SETUP@.
        (PATH): Use GROFF_RUNTIME.

        * src/roff/nroff/Makefile.sub (nroff): Call SH_DEPS_SED_SCRIPT.
        Don't substitute @SEP@ and @BINDIR@.
        * src/roff/nroff/nroff.sh: Use @GROFF_BIN_PATH_SETUP@.
        (PATH): Use GROFF_RUNTIME.

2004-04-05  Keith Marshall  <keith.d.marshall@ntlworld.com>

        * src/roff/nroff/nroff.sh: Implement work-around for sh.exe from
        Cygwin which doesn't handle stderr correctly.

2004-03-08  Werner LEMBERG  <wl@gnu.org>

        * Makefile.comm (install_dev, uninstall_dev): Protect `for' loops
        against empty argument.  Problem reported by <cgd@broadcom.com>.

2004-03-05  Keith Marshall  <keith.d.marshall@ntlworld.com>

2004-03-05  Werner LEMBERG  <wl@gnu.org>

        * fonts/devlj4/Makefile.sub (LJ4RES): Set to 1200.  This helps to
        reduce alignment problems with newer printers which use built-in
        TrueType fonts (instead of the older Intellifonts).  The ideal
        solution is to provide a second set of groff metric files, but this
        is extremely time-consuming to produce, given that HP's metric
        files are very rudimentary.

2004-03-01  Werner LEMBERG  <wl@gnu.org>

        (char_buffer::do_html, char_buffer::do_image) [DEBUGGING]: Fix calls
        to `set_redirection' and `save_and_redirect'.
        (usage): Fix message.
        (makeTempFiles, main): Use `DEBUG_FILE'.

          .di

        produces `x a' instead of `xa'.  This is a temporary fix, disabling
        font changes in diversions for -Thtml.

        * src/devices/grops/ps.cc (subencoding): New structure.
        (style): Add `sub' field.
        Updated all users.
        (ps_printer): Add `subencodings' and `next_subencoding_index' fields.
        Add `set_subencoding', `get_subfont' and `encode_subfont' member
        functions.
        Updated all users.
        (ps_printer::set_char): Use `set_subencoding'.
        (make_subencoding_name): New function.

        Updated all callers.
        This allows to get lines of arbitrary length.
        Use `valid_input_table'.
        Remove warning about non-conforming PS line length.  This seems
        not to be of great importance -- for example, dvips don't emit
        a warning either.
        (PS_LINE_MAX): Removed.
        (matches_comment): Change first argument to be of type `string &'.

        on the font encoding.
        * tmac/ps.tmac: Add `fi' and `fl'.
        Improve `Fi' and `Fl'.
        * tmac/X.tmac, tmac/lbp.tmac, tmac/tty.tmac: Improve `Fi' and `Fl'.

        * tmac/groff_mdoc.man: Fix description of `Dt'.

2003-02-26  Egil Kvaleberg  <egil@kvaleberg.no>

        * font/devps/prologue.ps: Fix for included Postscript that does
        a setpagedevice -- which is now safely ignored.

        * NEWS: Updated.

        * src/devices/grops/ps.cc: Now sets the page size in the generated
        document.  This is done in two ways: Via a %%-comment for gv and
        the like, and via a PageSize and setpagedevice for programs that
        understands Postscript proper, like ps2pdf.

        * src/devices/grops/ps.h: New broken-flag to avoid page size
        definition, if required.

        * src/devices/grops/grops.man: New broken-flag 16 mentioned.

        * src/utils/afmtodit/Makefile.sub (afmtodit): Handle @FONTDIR@.
        * src/utils/afmtodit/afmtodit.man: Document it.

        * NEWS: Updated.

        CJK punctuation characters U+3008 and U+3009.

        `+e' for position 34.

        Improve hyphenation slightly.  This is a first step in redesigning
        the hyphenation algorithm to make it more flexible (e.g. allowing
        kerns and ligatures between the hyphenation character and the
        following character -- while not used normally in English, other
        languages like German would benefit).

        * src/roff/troff/env.cc (environment::hyphenate_line): Use
        assertion instead of if-clause.
        Let `get_hyphen_list' return the number of involved characters in
        the hyphenation pattern instead of computing it directly (which

2002-11-10  Werner LEMBERG  <wl@gnu.org>

        Added three new requests `schar', `fschar', and `rfschar'.  `schar'
        defines a glyph which is searched after the check for fonts declared
        with `.special' (and before the check for all mounted special
        fonts).  `fschar' defines a glyph for a particular font which is
        searched after the check for fonts declared with `.fspecial' (and
        before the check for fonts declared with `.special').  `rfschar'
        removes glyphs defined with `fschar'.

2002-10-02  Werner LEMBERG  <wl@gnu.org>

        Redesigning color support in troff.  Colors are no longer
        represented as separate nodes but are now part of glyph nodes and
        friends.  This fixes the current formatting misbehaviour due to the
        changes introduced on 2002-09-20.  Some extra code is necessary for
        proper grotty support: Without adding color variables to
        space-related nodes, the background color would be changed too late.

        * src/roff/troff/node.h, src/roff/troff/node.cc:
        s/current_pagecolor/current_fill_color/.
        s/current_glyphcolor/current_glyph_color/.

        Changing the substring request to make it fit better with other
        string manipulation functions in other programming languages:
        Index 0 is now the first character in the string, and index -1
        indicates the last character.  Since this request didn't work
        properly anyway in the last release, it doesn't harm too much to
        change the syntax.

        Improve handling of hyphenation patterns.  It is now possible to
        use most of TeX's pattern files unmodified.  To make the process
        more flexible, a new request `hpfcode' has been added which
        provides a character code mapping for the `hpf' request.  See
        comment before hpf_getc() for more details.

        * src/roff/troff/charinfo.h (charinfo::get_translation_input): New
        inline function.

        * src/roff/troff/env.cc (WORD_MAX): Reduced to 256 since `unsigned
        char' is used for offsets in hyphenation exceptions.

        * tmac/hyphen.us: Replace with contents of unmodified `hyphen.tex'.

2002-02-06  Werner LEMBERG  <wl@gnu.org>

        Implementing color support in grotty.  The new switch -c activates
        the old drawing scheme, disabling color at the same time.  The new
        switch `-i' selects italic instead of underlining (SGR only).

        * src/devices/grotty/tty.cc (putstring): New define instead of
        `fputs'.  Updated all callers.

        `is_underline', `is_bold', `cu_flag', `tty_colors'.
        New methods `make_underline', `make_bold', `color_to_idx',
        `change_color', `put_color'.
        (cu_flag): Moved into `tty_printer' class.
        (tty_printer::tty_printer): Initialize colors.
        (tty_printer::add_char, tty_printer::set_char, tty_printer::special,
        tty_printer::draw, tty_printer::end_page): Handle colors also.
        (main): Add options `-c' and `-i'.

        * src/libs/libgroff/errarg.c: Implement it.

        * src/libs/libdriver/input.cc (parse_D_command, do_file): Add
        call to `pr->change_color'.

        troff_output_file::glyph_color): Call `do_motion'.

        * tmac/tty.tmac: Add color definitions.

        * src/roff/groff/groff.man: Minor fixes.

2002-02-05  Bernd Warken  <bwarken@mayn.de>

        * src/libs/libdriver/input.cc: Introduce `EnvInt' typedef and use
        it.  This is a preparation for future changes.

2002-02-05  Werner LEMBERG  <wl@gnu.org>

        * src/roff/troff/input.cc (process_input_stack): Fix the case
        where leading spaces are followed by \f or \s; previously, an
        incorrect space width has been used.

        * doc/roff.man (quoted_char): Fix argument.
        (comment): Define string.

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

        * doc/groff.texinfo: More fixes.

2002-02-04  Werner LEMBERG  <wl@gnu.org>

        * src/preproc/eqn/box.cc (output_string): Don't use \\*[...].
        * src/preproc/eqn/main.cc (do_file, inline_equation): Call
        `restore_compatibility' before `output_string' -- the LINE_STRING
        register now already contains proper switches from and to
        compatibility mode.

        * man/groff_char.man: Add Euro symbol.
        * man/groff_diff.man: Improve documentation of `.am1' and `.as1'.

        texinfo->pdf.
        (.texinfo.html): Add support for texinfo->html.

2002-02-03  Werner LEMBERG  <wl@gnu.org>

        Added three new requests `ds1', `as1', and `ami'.  The former two
        are equivalent to `ds' and `as' with the difference that
        compatibility mode is saved on entry, switched off during string
        expansion, and restored on exit.  The latter is the pendant to `dei'
        for `am'.

        (do_define_string): Use `define_mode' and `calling mode'.
        Insert COMPATIBLE_SAVE and COMPATIBLE_RESTORE at the beginning and
        end of string, respectively.

        (define_nocomp_string, append_nocomp_string,
        define_string_indirect): New functions.
        (init_input_requests): Updated.
        * NEWS, man/groff_diff.man, man/groff.man: Document it.

        * src/preproc/eqn/box.cc (box::top_level, box::extra_space): Use
        `as1' for assigning LINE_STRING (this is `10' usually).  Sun's
        mm macro package accesses this string register directly.
        * src/preproc/eqn/main.cc (inline_equation): Use `as1'.

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

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

        * doc/groff.texinfo, tmac/groff_ms.man: More fixes.

2002-01-31  Werner LEMBERG  <wl@gnu.org>

        * tmac/an-old.tmac (I): Use \, and \/ to improve spacing.

2002-01-31  Bernd Warken  <bwarken@mayn.de>

        * man/groff_out.man: Revised and updated.

2002-01-30  Bernd Warken  <bwarken@mayn.de>

        * src/libs/libdriver/input.cc [USE_ENV_STACK]: New macro to comment
        out the unused `{' and `}' commands.  Undefined by default.
        (IntArray): Make `data' private.
        (IntArray::operator[], IntArray::get_data, IntArray::len): Use these
        new methods instead.
        (skip_line_D, skip_to_end_of_line): New functions.
        (get_D_fixed_args): Use `skip_line_D'.
        Changed to handle dummy odd arguments by ...
        (get_D_fixed_args_odd_dummy): This new function.
        (get_D_variable_args): Split some code into ...
        (get_possibly_integer_args): This new function.
        (send_draw): Use more `const'.
        (delete_current_env): New function.
        (position_to_end_of_args): Use `size_t'.
        Updated.
        (send_draw): Updated.
        (parse_D_command): Handle `c', `C', and `t' better.
        Updated.
        (do_file): Updated.

2002-01-29  Werner LEMBERG  <wl@gnu.org>

        * NEWS: Revised.
        * doc/groff.texinfo: Introduce @Def...List, @Def...Item, and
        @Def...ListEnd which replaces @Def...x.  This is necessary to get
        proper HTML output -- see the comment in the file for more

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.

        * src/libs/libgroff/itoa.c (UINT_DIGITS): New macro.
        (ui_to_a): New function.
        * src/include/lib.h: Updated.

        * src/include/color.h (color_scheme): Replace `NONE' with `DEFAULT'.
        (color): Simplified; removed all `double' members and methods.
        A new array `components' now holds the color parameters.
        (color::is_default, color::get_components): New methods.
        (color::operator==, color:operator!=): New.
        (Red, Green, Blue, Cyan, Magenta, Yellow, Black, Gray): New macros
        to make access to the `components' array more comprehensible.
        * src/libs/libgroff/color.cc: Implement new color support.
        (atoh): Small fixes.
        (color::read_encoding): Simplified for new troff intermediate color
        output format.
        (default_color): New global variable.

        * src/roff/troff/input.cc (default_symbol): New global variable.

        (troff_output_file::hex): Removed.

        Updated to include/color.h and libdriver/input.cc.

        * src/preproc/pic/object.cc (draw_arrow): New parameter to set
        fill color properly (identically to the outline color).  \D'f...'
        doesn't work any more.
        All function calls to it updated.

        * src/devices/grohtml/post-html.cc (html_printer::do_body, main):
        Updated.
        * src/devices/grohtml/html-text.cc (html_text::issue_color_begin):

        and text in the right order.
        Updated.
        Remove branches for `f' and `F'; this is handled by
        libdriver/input.cc.

2001-10-04  Werner LEMBERG  <wl@gnu.org>

        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.
        * src/include/printer.h: Include color.h.

        Handle `m' and `DF' troff commands.
        * src/libs/libgroff/color.cc: New file.
        * src/libs/libgroff/Makefile.sub: Updated.

        Added skeleton macro for defunct macros.

        Updated documentation.

        When inside displays, an empty input line warning should be
        suppressed.  If another macro call is put inside a display,
        all subsequent empty lines found in that display caused a
        warning to be emitted.

2001-04-10  Ruslan Ermilov  <ru@freebsd.org>

        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).

        (doc-in-synopsis-section): New variable.  Updated all related
        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.

2001-03-04  Gaius Mulley  <gaius@glam.ac.uk>

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

        * src/devices/grohtml/post-html.cc: Adding UNICODE_DESC_START.
        (html_printer::add_to_sbuf): Changing type of `code' parameter.

        * src/roff/troff/node.cc (space_node::get_hyphenation_type): New
        method.  Return `HYPHEN_MIDDLE' if it was `\:'.
        * src/roff/troff/node.h: Updated.

2001-02-17  Ruslan Ermilov  <ru@FreeBSD.org>

        * 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.

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

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

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

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.
        * 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.

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.

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/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.

        * 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.

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

        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.

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

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

        used before -ms.

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

        * tmac.doc: Minor documentation fix.

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

        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.

        * MORE.STUFF: Added info about port to DOS.
        * NEWS, win32-diffs: Updated.

        * src/include/nonposix.h: Remove first line -- this file is used

        because it has more than one dot in its trunk, replace the dot
        with an underscore and try again.
        (do_file): Use FOPEN_RB instead of "r".  Skip every CR before a
        Newline.
        [__MSDOS__ || _MSC_VER]: Stop at the first ^Z character.

        * src/utils/hpftodit/hpftodit.cc: #include nonposix.h.
        (File::File): Open the input file in binary mode.  Strip CR
        characters from each CR-LF pair.
        (xbasename): Support file names with several possible slash-type
        characters, as given by DIR_SEPS[] in nonposix.h.

        call to pclose, a suitable macro is now defined on nonposix.h.
        Use the portable macros WIFEXITED, WIFSIGNALED, WTERMSIG, WSTOPSIG

        (remove_tmp_files, add_tmp_file): New functions.
        (xtmpfile): Record temporary files and register an atexit function
        to delete them explicitly, instead of relying on the OS to do
        that, which doesn't work on non-Unix systems.

        * src/libs/libgroff/searchpath.cc: #include nonposix.h.
        (search_path::search_path): Use PATH_SEP instead of a literal

        etc. can include a semi-colon on DOS/Windows.
        (depend.temp): Use depend1.temp instead of depend.temp1, to
        prevent files from overerwiting each other on 8+3 filesystems.

        * gendef.sh (t): Change definition to work with DOS/Windows.

        doc/groff.texinfo: Apart of some typo corrections, I also changed

        dummy function.
        * src/roff/troff/node.cc: Use special versions of popen() in
        real_output_file() and pclose() in ~real_output_file().

2000-02-27  Werner LEMBERG  <wl@gnu.org>

        Adding a new driver, grolbp, for Canon CAPSL printers (LBP-4 and

2000-02-22  Werner LEMBERG  <wl@gnu.org>

        * src/preproc/grn/main.cc: Slight formatting.

        * src/roff/groff/groff.man: Added an example.

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.

        vertical position and return to it before turning traps on again.
        
Thu Jul 26 02:54:32 1990  James Clark  (jjc at yquem)

        * troff/node.c, troff/node.h: In classes derived from node,
        replace prev_char_width method by last_char_node method.
        * troff/env.c (environment::get_prev_char_width): Use
        node::last_char_node rather than node::get_prev_char_width.

        * Makefile: Added comment about -fno-inline on 68030-based
        Apollos.

        * troff/reg.c (number_format_to_ascii), eqn/delim.c (DELIM_TABLE_SIZE),

        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

        * tbl/table.h (class table): Add `keep' member.
        * tbl/table.c (table::table): Initialize `keep'.

        be included in a C compilation.
        (iftoa): Use INT_DIGITS. Include lib.h.

        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.
        (table::define_bottom_macro): Use REPEATED_VPT_MACRO instead of
        vpt.
        (table::do_row): Likewise.

        * tbl/table.c (vertical_rule::print): Prefix the .sp -1 line with
        TRANSPARENT_STRING_NAME.

        * tbl/table.c (table::init_output): In the table release macro
        print an error message and don't produce any output if after
        issuing the need request the table still will not fit.  Also
        remove the diversion after bringing it back.

        * tbl/table.c (table::init_output): Define a new macro
        REPEATED_MARK_MACRO, like mk but if in a diversion also

        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.

        entry starting from 1 unless \nC is > 0, like Sun.  Added an
        optional 5th argument to .TH which specifies the manual name and
        appears in the center of the header.  Understand the X, P and D
        registers like Sun.

        title into read_title_parts.
        * troff/input.c (read_title_parts): New function.  Check the
        input_level when testing whether a token matches the delimiter.

        * troff/input.c (exit_request): New function.
        * troff/input.c (init_input_requests): Bind ex request to
        exit_request rather than exit_groff.

        * troff/input.c (exit_groff): Call tok.next() before

        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/token.h: Remove TOKEN_FLUSH_PENDING_LINES.

Sun Jul 15 10:50:08 1990  James Clark  (jjc at yquem)

        * 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.

        * lib/lib.h: If CFRONT_ANSI_BUG is defined, cast INT_MIN to long.
