<p>groff</p><ul>
<p><li>XHTML support has been added to grohtml and can be
specified by −Txhtml. This option also utilizes the
MathML capability of eqn and combines the outputs of both in
the final XHTML file. Users can also specify the
‘−P−V’ option together with
‘−Txhtml’ in groff. This has the effect of
creating an XHTML validator button at the bottom of each
page.</p>
<p style="margin-top: 1em"></li><li>Some options have been
added to control a new preprocessor, ‘preconv’
(see below): ‘−k’ activates it,
‘−K’ sets the input encoding, and
‘−D’ sets the default encoding.</p>
<p style="margin-top: 1em"></li><li>A new environment
variable ‘GROFF_ENCODING’ sets the encoding of
input files; it implies command option
‘−k’. </li></p></ul>
<p>troff</p><ul>
<p><li>Two new requests ‘device’ and
‘devicem’ have been added which are equivalents
to the \X and \Y escapes, respectively.</p>
<p style="margin-top: 1em"></li><li>A new read-only number
register ‘.br’ is available which is set
to 1 if a macro is called as .foo and to 0 if
called as ’foo. This allows to reliably modify
requests.</p>
<pre style="margin-left:3%; margin-top: 1em">.als bp@orig bp
.de bp
. tm before bp
. ie \\n[.br] .bp@orig
. el ’bp@orig
. tm after bp
..</pre>
<p style="margin-top: 1em"></li><li>A new request
‘fzoom’ has been added to adjust the optical
size of a font in relation to the others. The zoom factor is
given in integer multiples of 1/1000th. In the following
example, the CR font is magnified by 10% (the zoom factor is
1.1).</p>
<pre style="margin-left:3%; margin-top: 1em">.fam P
.fzoom CR 1100
.ps 12
Palatino and \f[CR]Courier\f[]</pre>
<p style="margin-top: 1em">The new number register
‘.zoom’ holds the zoom value of the current
font, in multiples of 1/1000th.</p>
<p style="margin-top: 1em"></li><li>The
‘cflags’ request has been extended with a new
flag value 64, to be used in combination with values 2
(break before character) and 4 (break after character).
If set, the hyphenation codes of the surrounding characters
are ignored.</p>
<p style="margin-top: 1em"></li><li>A new debugging
request, ‘pev’, has been added to print all of
the current known environments to stderr. It first prints
the state of the current environment, then iterates through
all of the known environments, printing each except the one
that is current.</p>
<p style="margin-top: 1em"></li><li>A new escape
‘\$^’ has been added. It represents the
parameters of a macro as if they were an argument to the
‘ds’ request. This is used by
‘trace.tmac’.</p>
<p style="margin-top: 1em"></li><li>A new read-only number
register ‘.O’ is available which returns the
current suppression level as set by the ‘\O’
escape.</p>
<p style="margin-top: 1em"></li><li>The space width emitted
by the ‘\|’ and ‘\^’ escape
sequences can be controlled on a per-font basis. If there is
a glyph named ‘\|’ or ‘\^’,
respectively (note the leading backslash), defined in the
current font file, use this glyph’s width instead of
the default value.</p>
<p style="margin-top: 1em">This behaviour is not new, but
hasn’t been documented before. </li></p></ul>
<p>nroff</p><ul>
<p><li>Two new command line options ‘−w’
and ‘−W’ are accepted and passed to groff
to enable and disable warning messages, respectively.
</li></p> </ul>
<p>preconv</p><ul>
<p><li>This is a new preprocessor to convert various input
encodings to something groff understands (this is, ASCII and
\[uXXXX] entities, with ‘XXXX’ a hexadecimal
number with 4 to 6 digits, representing a Unicode input
code). Normally, preconv should be invoked with options
‘−k’ and ‘−K’ of groff.
See the preconv man page for details. </li></p></ul>
<p>pic</p><ul>
<p><li>int(x) now really behaves as documented: It
truncates the non-integer part of x, this is, it rounds
towards zero and not towards the next integer less than or
equal to x.</p>
<p style="margin-top: 1em"></li><li>Pic now supports up to
32 macro arguments (and up to 16 on EBCDIC platforms).</p>
<p style="margin-top: 1em"></li><li>Heinz-Jürgen
Ãrtel contributed code for two new keywords,
‘xslanted’ and ‘yslanted’, which can
change the shape of boxes into arbitrary parallelograms.
</li></p> </ul>
<p>tbl</p><ul>
<p><li>Latest versions of DWB tbl introduced an
‘x’ column specifier for a single column
expanded to the line width. GNU tbl has now been extended to
support even multiple ‘x’ specifiers within a
table.</p>
<p style="margin-top: 1em"></li><li>To avoid collision with
the new ‘x’ specifier, a block formatting macro
must now be selected with specifier letter ‘m’.
</li></p> </ul>
<p>eqn</p><ul>
<p><li>Eric S. Raymond has added a new device type to eqn,
MathML. When −TMathML is enabled, eqn now emits MathML
formula markup rather than groff commands. The new groff
−Txhtml device uses this. </li></p></ul>
<p>chem</p><ul>
<p><li>The preprocessor ‘chem’ was added.
‘chem’ is a roff language to generate chemical
structure diagrams. It generates ‘pic’ output.
</li></p> </ul>
<p>grops</p><ul>
<p><li>The PS font definition files have been regenerated
with newer AFM versions from Adobe’s 35 core fonts as
present in most Level 2 PS printers. The changes are
minor (most notably, the addition of the ‘Euro’
glyph and an extended set of kerning values).</p>
<p style="margin-top: 1em">For backwards compatibility, the
old set of font definition files is still available; for
details please read the man page of grops. </li></p></ul>
<p>grotty</p><ul>
<p><li>\D’p...’ is now supported if the polygon
consists entirely of horizontal and vertical lines.
</li></p> </ul>
<p>grohtml</p><ul>
<p><li>XHTML support has been added.</p>
<p style="margin-top: 1em"></li><li>New command line option
‘−V’ (to be used in XHTML mode) to produce
an XHTML validator button.</p>
<p style="margin-top: 1em"></li><li>New command line option
‘−y’ to produce a right-justified groff
signature at the end of the document (in combination with
option ‘−V’). </li></p></ul>
<p>gxditview</p><ul>
<p><li>Support for keyboard navigation has been
improved.</p>
<p style="margin-top: 1em"></li><li>Similar to other X11
applications, there are now two resource files,
‘GXditview’ and ‘GXditview-color’.
</li></p> </ul>
<p>groffer</p><ul>
<p><li>‘groffer’ version 1.* exists now in a
shell and a Perl version. </li></p></ul>
<p>afmtodit</p><ul>
<p><li>New option ‘−c’ to output more
font information as comments.</p>
<p style="margin-top: 1em"></li><li>New option
‘−k’ to suppress output of kerning
data.</p>
<p style="margin-top: 1em"></li><li>New option
‘−f NAME’ to set the internal name of the
groff font. </li></p></ul>
<p>macro packages</p><ul>
<p><li>Joachim Walsdorff contributed the
‘hdtbl’ package for the generation of tables,
using a syntax very similar to the HTML table model. For
example, a table with two cells and two rows looks like
this:</p>
<pre style="margin-left:3%; margin-top: 1em">.TBL cols=2
. TR .TD 1*1 .TD 1*2
. TR .TD 2*1 .TD 2*2
.ETB</pre>
<p style="margin-top: 1em">Here the same table using a more
expanded syntax:</p>
<pre style="margin-left:3%; margin-top: 1em">.TBL cols=2
. TR
. TD 1*1
. TD 1*2
. TR
. TD 2*1
. TD 2*2
.ETB</pre>
<p style="margin-top: 1em">Tables can be nested;
‘hdtbl’ works without a preprocessor so that the
full capability of groff’s macro engine is
available.</p>
<p style="margin-top: 1em">This package currently works
with ‘-Tps’ only.</p>
<p style="margin-top: 1em"></li><li>−mandoc now
supports multiple man pages (in either man or mdoc
format).</p>
<p style="margin-top: 1em"></li><li>Fabrice
Ménard contributed locales support. In
particular, it is now possible to get French localization of
the main macro packages (−ms, −mm, −me,
and −mom, but not −man and −mdoc which are
localized differently) by appending ‘-mfr’ to
the list of macro packages. Example:</p>
<pre style="margin-left:3%; margin-top: 1em">groff −ms −mfr foo > foo.ps</pre>
<p style="margin-top: 1em">Note that latin-9 input encoding
is used for French (to support the ‘oe’
ligature).</p>
<p style="margin-top: 1em"></li><li>Swedish macro
localization (with ‘−msv’) has been
added.</p>
<p style="margin-top: 1em"></li><li>German macro
localization (with ‘−mde’ and
‘−mden’ for traditional and new
orthography, respectively) has been added.</p>
<p style="margin-top: 1em"></li><li>Czech macro
localization (with ‘−mcs’) has been
added.</p>
<p style="margin-top: 1em">Note that latin-2 input encoding
is used for Czech.</p>
<p style="margin-top: 1em"></li><li>A new macro
‘Dx’ has been added to the mdoc package which
identifies the DragonFly OS.</p>
<p style="margin-top: 1em"></li><li>If mdoc is used to
print multiple man pages (together with the −rcR=0
command line option), each man page now starts a new
page.</p>
<p style="margin-top: 1em"></li><li>−mtrace has been
considerably improved, now showing number and string
register assignments, among other things. See the
groff_trace man page for details.</p>
<p style="margin-top: 1em"></li><li>The PSPIC macro now
works with all devices (producing a hollow rectangle on
devices which don’t support inclusion of PS images)
and is loaded in troffrc at start-up.</p>
<p style="margin-top: 1em"></li><li>A new auxiliary macro
package ‘62bit’ has been added which provides
some macros for adding, multiplying, and dividing signed
62bit integers (mainly to handle normal groff number
operations without risking overflow errors).</p>
<p style="margin-top: 1em"></li><li>For −ms, Eric S.
Raymond contributed support for ancient Bell Labs localisms
‘.SC’, ‘.UC’, ‘.P1’, and
‘.P2’. The latter three are enabled only after
.SC is called.</p>
<p style="margin-top: 1em"></li><li>A new string,
‘SN-STYLE’, has been added to the ms macros,
controlling the formatting of section numbers in headings
defined by ‘.NH’.</p>
<p style="margin-top: 1em"></li><li>The new macro package
‘ptx’ provides a template definition for the
‘.xx’ macro as needed by GNU ptx (for creating
permuted indices). </li></p></ul></td></tr></table><hr>
