</td><td valign="top" width="70%">
<p>troff</p><ul>
<p><li>Analogously to the .ft and \f pair, two new requests
‘gcolor’ and ‘fcolor’ (which pair
with \m and \M, respectively) have been added to set the
glyph and background colours.</p>
<p style="margin-top: 1em"></li><li>A new read-only,
string-valued register ‘.sty’ returns the name
of the current style.</p>
<p style="margin-top: 1em"></li><li>Two new conditional
operators ‘F ⟨name⟩’ and
‘S ⟨name⟩’ have been added.
‘F’ is true if a font ⟨name⟩ exists.
‘S’ is true if a style ⟨name⟩ has been
registered.</p>
<p style="margin-top: 1em"></li><li>Cyrillic characters
have been added to the ‘utf8’ and
‘html’ output devices. </li></p></ul>
<p>pic</p><ul>
<p><li>The ‘by’ argument in a ‘for’
loop can now be negative if it is additive. For the
multiplicative case, it must be greater than zero. </li></p></ul>
<p>eqn</p><ul>
<p><li>The following keywords aren’t new but
haven’t been documented previously:</p>
<p style="margin-left:3%; margin-top: 1em"><b>undef
NAME</b> (to undefine a macro) <b><br>
copy "FILE"</b> (a synonym for
‘include’) <b><br>
space n</b> (to modify the vertical spacing before and after
an equation)</p>
<p style="margin-top: 1em"></li><li>The following macros
aren’t new but haven’t been documented
previously:</p>
<p style="margin-left:3%; margin-top: 1em"><b>Alpha, ...,
Omega</b> (the same as ‘ALPHA’, ...,
‘OMEGA’) <b><br>
ldots</b> (three dots on the base line) <b><br>
dollar</b> (a dollar glyph)</p>
<p style="margin-top: 1em"></li><li>The following keywords
have been extended. Again, this isn’t new but
hasn’t been documented previously:</p>
<p style="margin-left:3%; margin-top: 1em"><b>col n { ... }
<br>
lcol n { ... } <br>
rcol n { ... } <br>
ccol n { ... } <br>
pile n { ... } <br>
lpile n { ... } <br>
rpile n { ... } <br>
cpile n { ... }</b> (set vertical spacing between rows
to N) </li></p></ul>
<p>grohtml</p><ul>
<p><li>This device driver has been raised to beta stage;
its set of tags should be stable now.</p>
<p style="margin-top: 1em"></li><li>New command-line option
‘−s’ to set the base point size.</p>
<p style="margin-top: 1em"></li><li>New command-line option
‘−S’ to set the split level while
generating multiple files. </li></p></ul>
<p>grotty</p><ul>
<p><li>Experimental support for zero-width and double-width
characters. </li></p></ul>
<p>gxditview</p><ul>
<p><li>On platforms which have the X Window System
this program is now built and installed automatically.
</li></p> </ul>
<p>xtotroff</p><ul>
<p><li>This program to create font definition files for
xditview isn’t new but hasn’t been installed
previously. </li></p></ul>
<p>groffer</p><ul>
<p><li>A security problem (reported as CAN-2004-0969) has
been fixed. </li></p></ul>
<p>gdiffmk</p><ul>
<p><li>A new script contributed by Mike Bianchi. It
compares two groff, nroff, or troff documents and creates an
output with added margin characters (using
‘.mc’) to indicate the differences. </li></p></ul>
<p>pdfroff</p><ul>
<p><li>A new wrapper script contributed by Keith Marshall
to easily create PDF documents with groff. </li></p></ul>
<p>macro packages</p><ul>
<p><li>ms.tmac</p><ul>
<p><li>Support for fractional point sizes: A value for the
‘PS’, ‘VS’, ‘FPS’, and
‘VPS’ register larger than or equal to 1000 is
always divided by 1000. For example,
‘.nr PS 10250’ sets the
document’s font size to 10.25 points.</p>
<p style="margin-top: 1em"></li><li>The ‘Ds’
and ‘De’ macros provided in ms since groff
version 1.19 have been removed; the equivalent
‘DS’ and ‘DE’ macros should be used
instead. X11 documents which actually use ‘Ds’
and ‘De’ always load a specific macro file from
the X11 distribution (‘macros.t’) which provides
proper definitions for the two macros.</p>
<p style="margin-top: 1em"></li><li>The following registers
have been added for improving layout control:</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="13%">
<p style="margin-top: 1em">PORPHANS</p></td>
<td width="87%">
</td></tr>
</table>
<p style="margin-left:8%;">Defines number of lines
following ‘LP’, ‘PP’,
‘QP’, ‘IP’ or ‘XP’ which
must be kept together, before any automatic page break.</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="13%">
<p style="margin-top: 1em">HORPHANS</p></td>
<td width="87%">
</td></tr>
</table>
<p style="margin-left:8%;">Sets number of lines of
following paragraph which must be kept with a heading,
defined by ‘NH’ or ‘SH’, before any
automatic page break.</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="10%">
<p style="margin-top: 1em">GROWPS</p></td>
<td width="90%">
</td></tr>
</table>
<p style="margin-left:8%;">Sets the first level of heading
(set with ‘NH’) which keeps the same point size
as body text.</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="10%">
<p style="margin-top: 1em">PSINCR</p></td>
<td width="90%">
</td></tr>
</table>
<p style="margin-left:8%;">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’
produces 14pt headings, ‘.NH 2’ produces
12pt, and all other levels remain at 10pt (because
\n[PS] = 10).</p>
<p style="margin-left:8%; margin-top: 1em"></li><li>The
‘SH’ 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. </li></p></ul>
<p style="margin-top: 1em">Please refer to the
documentation of the ms package for other, minor
improvements.</p>
<p style="margin-top: 1em"></li><li>me.tmac</p>
<p style="margin-top: 1em">The section type set with the
‘++’ request is available in the
‘_M’ register. This isn’t new but
hasn’t been documented before.</p>
<p style="margin-top: 1em"></li><li>www.tmac</p>
<p style="margin-top: 1em">The ‘HR’ macro no
longer causes an empty line for non-HTML devices.</p>
<p style="margin-top: 1em">A new macro ‘HEAD’
has been added to directly add data to the
<head>...</head> block.</p>
<p style="margin-top: 1em">New macros ‘OLS’ and
‘OLE’ to start and end an ordered list.</p>
<p style="margin-top: 1em">New macros ‘DLS’ and
‘DLE’ to start and end a definition list.
</li></p> </ul>
<p>pdfmark</p><ul>
<p><li>A new macro package contributed by Keith Marshall
which implements PDF marks. This is in alpha stage
currently. </li></p></ul>
<p>miscellaneous</p><ul>
<p><li>Two new keywords to the DESC file have been added
which are needed for grohtml: ‘image_generator’
and ‘unscaled_charwidths’. The former gives the
name of the program which creates PNG images, and the latter
makes troff always use unscaled character widths. </li></p></ul></td></tr></table><hr>
