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/.

        accordingly.
        (vmotion_node::col): New variable.
        Updated constructor accordingly.

        environment::make_tab_node, environment::add_padding, title):
        Updated.
        (environment_switch, environment_copy): Don't add color nodes.

        * src/roff/troff/input.cc (do_glyph_color, do_fill_color): Return
        nothing.

        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

        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.

        (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'.
        (usage): Updated.
        * NEWS, src/devices/grotty/grotty.man: Updated.

        * src/include/errarg.h (errarg): Add support for `unsigned int'.
        * src/libs/libgroff/errarg.c: Implement it.

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

        * 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'.

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.

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::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.

        * 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):

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.
        (environment): New members `col' and `fill'.

        * src/include/Makefile.sub: Updated.

        * src/libs/libdriver/input.cc (do_file): Initialize `env.col' and
        `env.fill'.
        Handle `m' and `DF' troff commands.
        * src/libs/libgroff/color.cc: New file.
        * src/libs/libgroff/Makefile.sub: Updated.

        * src/preproc/html/pre-html.cc (IMAGE_BORDER_PIXELS): Set to 2.

        `set_fill_color'.
        (closed_object): Add member function `set_fill_color'.
