2007-02-09  Eric S. Raymond  <esr@snark.thyrsus.com>

        A try at the new rule for block column allocation is now enabled by
        the new `experimental' global option: The horizontal space up to the
        right margin which is not used by columns without text blocks is
        evenly distributed to the columns with text blocks.

        It doesn't work right as yet; there appears to be some error in the
        computation of `3avail', the available line length.  The purpose of
        this patch is (a) to make experimenting with other formulas easy,
        and (b) leave the infrastructure for flag `experimental' in place
        for future experiments.  Do not document any behavior associated
        with this flag!

        * src/preproc/tbl/table.h: Include `stdbool.h'.
        (table): Make `flags' public.
        Add `count_block_columns' function.
        Add `blockflag' array.
        Add `EXPERIMENTAL' enumeration value.

        * src/preproc/tbl/table.cpp (AVAILABLE_REG, COLCOUNT_REG): New
        macros.
        (table_entry): New member `parent' so that class and subclass
        members can set a parent field.  Update all users.
        (block_entry::do_divert): Handle `EXPERIMENTAL' flag.
        (block_entry::do_width): Set the parent's `blockflag'.
        (table::allocate): Handle `blockflag'.
        (table::count_block_columns): New function.
        (compute_span_width): Adjust AVAILABLE_REG.
        (table::compute_widths): Handle COLCOUNT_REG and AVAILABLE_REG.

        * src/preproc/tbl/main.cpp (process_options): Handle `experimental'
        option.

        likely to do something surprising.
        
        * man/groff_out.man: We can simplify the command macros still
        further if we stop trying to hide structural requests inside them. 
        Also, fix some instances of \} at start of line without a dot, and
        make some font changes explicit in strings.
        
        * man/groff_out.man: Cleanup -- remove now-unneeded uses of .do and
        .cp.
        
        * man/groff_out.man: Final step: Reduce x-command, get rid of eo/ec
        calls and fix macros to do without them.  File should now be
        viewer-portable.
        
        * man/groff_out.man: Fourth step: Eliminate use of eqn in favor of
        micromotions that produce the same visual result and can be lifted
        to XML-DocBook.

        Add support for MathML output to eqn.  

        The strategy used is very simple and relies on the fact that the box
        models of eqn and Presentation MathML differ in only trivial ways. 
        It leaves the grammar and existing internal object structures
        unchanged.  A new global, `output_format', is defined as an
        enumerated type with values {troff, mathml}.  Most of the functions
        and methods that emit actual output acquire a top-level conditional,
        dispatching on this global, which has one arm for troff mode and one
        for MathML mode.  In most cases the MathML arm is drastically
        simpler.

        (This strategy could be easily generalized to support other output
        formats.  TeX is a possibility that leaps to mind.)

        The only even moderately tricky changes are in the lexer.  Some of
        the predefined macros used constructs like `up', `down', `fwd',
        `back', and `vcenter' that have no equivalents in MathML.  I
        attacked this problem in these ways:

        1. I eliminated three uses of `back' to compose characters in favor
           of using equivalent groff specials `\(<<', `\(>>', and `\(<>'
           that did not exist when these macros were written.  (This will be
           a quality improvement for troff users.)

        2. I eliminated one use of `vcenter' by using \\(md.  (Likewise...)

        3. I then split the table of pre-definitions in three; one large
           common table and two small troff-specific and MathML-specific
           tables.  Use of troff-only operations (up, down, back, fwd,
           vcenter) is now confined to the former.  The latter now uses
           `size big' and drops out the explicit positioning operations,
           counting on MathML processors to do them.

        POTENTIAL TROUBLE SPOTS:

        Here are notes for reviewers on places I'm not 100% sure I've done
        the right thing:

        * In the process of preparing the troff table, I translated three
          definitions (dot_def, dotdot_def, and utilde def) that previously
          used explicit \v escapes to use `up' and `down' instead.  I
          modeled the new definitions on the way `vec' and `dyad' work, but
          it's possible I got something subtle wrong.

        * I'm not certain the MathML implementation of font_box::output() is
          right, because I don't quite get what the switcheroo between
          `current_roman_font' and `old_roman_font' is supposed to
          accomplish.  It does seem to generare good MathML, though.

        Finally, I made one purely cosmetic change in `text.cpp'; I replaced
        with an enum some magic numbers for spacing types that I thought
        were too ugly to live.

        REMAINING ISSUES:

        The entirety of eqn is translated when `-TMathML' is specified, 
        with the following exceptions...

        Limitations that cannot be fixed include non-support for special,
        up/down/fwd/back, and vcenter.

        Limitations that might be fixable include non-support for mark and
        lineup.  I will investigate further, but if these can be implemented
        at all it's going to be in a very complicated and nasty way.

        The way character boxes are output means that each digit of a
        multi-digit number gets its own <mn></mn> tag pair in the MathHTML. 
        While this is not technically wrong for Presentation MathML, it is
        ugly and inefficient.  Fixing this will require implementing a
        little state machine in the `text.cpp' output method.

2005-12-30  Werner LEMBERG  <wl@gnu.org>

        New preprocessor `preconv' to convert input encodings to something
        groff can understand.  Not yet integrated within groff.  Proper
        autoconf stuff is missing too.

        Tomohiro Kubota has written a first draft of this program, and some
        ideas have been reused (while almost no code has been taken
        actually).

        * src/preproc/preconv/preconv.cpp. src/preproc/preconv/Makefile.sub:
        New files.

        The change 2005-06-20 can indeed cause problems, so we follow the
        advice by using marks.

        * font/devps/prologue.ps (PBEGIN): Use `mark'.

2005-06-22  Werner LEMBERG  <wl@gnu.org>

        Another round in fixing getopt problems.  Hopefully the last one!
        This time we use the getopt stuff from gnulib and define a prefix
        unconditionally so that there are no collisions with any other
        getopt implementations.  This is a slight waste of space in case
        we already use a GNU getopt implementation, but on
        the other hand it really simplifies life.

        * src/include/getopt.h: Use gnulib version.

        * src/include/getopt_int.h: Use gnulib version.

        * src/include/groff-getopt.h: Removed.  Obsolete now.

        * src/include/lib.h: Regarding getopt, don't handle any platform
        specially; just include getopt.h.
        (__GETOPT_PREFIX): Define (before getopt.h).

        * src/include/Makefile.sub (HDRS): Updated.

        * src/libs/libgroff/getopt1.c, src/libs/libgroff/getopt.c: Use
        gnulib version.

        * src/libs/libgroff/Makefile.sub (EXTRA_CFLAGS): Set
        __GETOPT_PREFIX.

        * src/utils/pfbtops/pfbtops.c, src/utils/xtotroff/xtotroff.c
        (__GETOPT_PREFIX): Define (before getopt.h).

2005-06-21  Werner LEMBERG  <wl@gnu.org>

        * src/include/lib.h: Provide a fix for Mac OS X to not include
        groff-getopt.h.

2005-06-20  Denis M. Wilson  <dmw@oxytropis.plus.com>

        * font/devps/prologue.ps (EP): Dont' use `bind'.  Reason: Using
        `bind' to define a procedure which contains `showpage' means that an
        invocation of `showpage' may execute wrongly (the exact effect
        depending on the interpreter).  Not usually a problem except under
        transformations, such as combining pages.
        (PEND): Don't call `clear'.  Reason: Using `clear' in the definition
        of /PEND means that stack underflow will occur if the stack is
        deliberately non-empty before document inclusion.  If included
        files are found to be generally badly behaved, we could replace the
        `clear' with `mark' in /PBEGIN and `cleartomark' in /PEND (I've
        never found this necessary).

2005-06-20  Jörgen Grahn  <jgrahn@algonet.se>

        * src/preproc/soelim/soelim.cpp (do_file): Append trailing zero
        earlier to get correct error message.

        * src/roff/nroff/nroff.sh: Add support for iso-8859-15.

2005-06-15  Werner LEMBERG  <wl@gnu.org>

        Another try to update getopt files.  This time we add a dummy
        gettext.h file to satisfy the dependency.

        * src/include/getopt.h, src/libs/libgroff/getopt.c,
        src/libs/libgroff/getopt1.c: Updated from GNU libc CVS.

        * src/include/getopt_int.h: New file (from GNU libc CVS).

        * src/include/gettext.h: Dummy file which just defines a gettext()
        macro.

        * src/include/groff-getopt.h: Updated.

        * src/include/Makefile.sub (HDRS): Add getopt_int.h and gettext.h.


        * src/libs/libdriver/input.cpp (IntArray): Remove superfluous
        `const' keywords in return value.

        These patches modify the indentation implementation to use `<p
        style=margin-left: n%>'.  Many thanks to Peter and Larry for
        suggesting this solution.  Grohtml only uses tables for `.IP' and
        related tags when the first operand has a short width.

        Similarly, they modify all vertical space code.  By default, grohtml
        sets up a style sheet which uses no vertical space between `table',
        `pre', and `p' tags.  It forces spaces when it needs them using
        `style="margin-top: 1em"'.

        * src/devices/grohtml/html-table.cpp: Include `html-text.h'.
        (html_table::emit_table_header, html_table::emit_new_row):

        (html_indent::end): Remove code in function.

        * src/devices/grohtml/html-table.h: Updated.
        (html_table): Make `out' public.

        * tmac/an-old.tmac (ne): Using default scaling operator.

2004-09-19  Keith Marshall  <keith.d.marshall@ntlworld.com>

        This change implements the following features:

        PORPHANS
          New numeric register: Defines number of lines following LP, PP,
          QP, IP or XP, which must be kept together, before any automatic
          page break.  If insufficient space remains on the current page, a
          page break is forced before the new paragraph begins.

        HORPHANS
          New numeric register: Sets number of lines of following paragraph
          which must be kept with a heading, defined by NH or SH, before any
          automatic page break.  If insufficient space remains on the
          current page, a page break is forced before the heading.

        GROWPS
          (Thanks to Joerg van den Hoff, for this idea).

          New numeric register: Sets the first level of heading (set with
          NH), which will keep the same point size as body text; e.g. if
          GROWPS is set to 3, .NH 3, .NH 4, ... will produce headings at the
          point size specified by \n[PS], but .NH 2 and .NH 1 will have
          progressively larger point sizes, determined by \n[PSINCR] (see
          below).

        PSINCR
          New numeric register: Sets the point size increment for each level
          of heading, (set with NH), below the threshold level set by
          GROWPS; e.g. if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p,
          then .NH 1 will produce 14pt headings, .NH 2 will produce 12pt,
          and all other levels will remain at 10pt, (because \n[PS] = 10).

        SH
          Existing macro now accepts a numeric argument, to make heading
          size match that of NH with same argument value, when the
          GROWPS/PSINCR feature is enabled.

        SN-DOT
          New string, set by NH macro, replaces the existing (undocumented)
          use of SN, to represent the assigned section number.

        SN-NO-DOT
          New string, set by NH macro, represents the assigned section
          number, but omits the terminal period (periods at intermediate
          levels are retained).

        SN
          String set by NH macro, originally undocumented, now implemented
          as an alias for SN-DOT (which reproduces original behaviour).

        * tmac/s.tmac (PORPHANS): New register.
        (par*start): Use it.
        (HORPHANS, GROWPS, PSINCR): New registers.

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.

        (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>

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

        * Makefile.comm (install_dev, uninstall_dev): Protect `for' loops

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

        * font/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'.

        `-o' option work.

        * src/roff/troff/div.cpp: Include nonposix.h.
        (cleanup_and_exit): Call FLUSH_INPUT_PIPE.

        Fix handling of &nbsp; in grohtml.  To do this, troff emits `N'

          .di
          x\*[xxx]

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

        `HTML-TAG'.

        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
        often yields too small values).
        * src/roff/troff/node.h (*::get_hyphen_list): Add second parameter.
        * src/roff/troff/node.cc (*::get_hyphen_list): Handle new second

        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'.
