This is a port of GNU Groff 1.22.3 to MSDOS/DJGPP.
Groff is a document-formatting and typesetting package. It belongs to an
older generation of word-processing software that is not WYSIWYG; instead,
you edit the document source with a text editor, intersperse the text with
special directives that specify fonts and formatting parameters, and then
submit the source to a batch processor which produces a ready-to-print or
ready-to-read document.
Groff includes the GNU implementation of the Unix-standard utilities troff
and nroff, and their companions pic, eqn, tbl, soelim, and others. It also
includes many macro packages, including man, the package of macros for
formatting man pages.
The DJGPP port of Groff is mainly used to format man pages.
DJGPP specific changes.
=======================
- Although all the DJGPP specific changes required to build the old groff-1.16
port have found their way into the official release code of groff, this port
requires some adjustments. This is because most of the non-posix code added
since then is very WIN32 centric and ignores pure DOS peculiarities specially
in pipeline.c. There are also some file names and directory names that are
not SFN clean and need to be adjusted so that the binary package installs
and works on plain DOS.
- The content of the /arch/djgpp of the official release has been replaced by
new files (config.bat, config.sed, config.site, etc). The original files
have been moved into /arch/djgpp/original.
- Groff requires some support programs to be available. If they have not been
ported to DJGPP then the corresponding functionality will not be available.
This concerns specially the functionality to convert man pages into pdf.
- To configure and build this port a C++ compiler and the latest port of perl
must be installed.
- The build system of groff is not the standard one produced with autotools.
This makes it very hard to adjust the DJGPP specific config files to the
path assumptions made in the Makefile.ins and the directory tree used. Due
to this reason the package has not been configured at all but all script
adjustments have been done to configure and compile the source code in the
/_build.205 directory. You should cd into the /_build.205 directory and
configure the sources like this:
..\arch\djgpp\config ./..
- Although some DJGPP/DOS specific fixes have been done to the various shell
and perl scripts not all of them may be operational. In this case you are
alone. If you are able to fix them, send a patch to me and it will be
include in the next port of groff.
- The default paths were groff and its programs search for fonts and other
scripts have changed since groff-1.16. The groff specific paths stored
in the djgpp.env file no longer reflects this and needs to be adjusted
accordingly.
- There are no DJGPP specific user visible changes.
- This is the first port that has been compiled using djdev205. Starting
with this port version I will no longer support neither djdev204 nor djdev203.
- The port has been tested by using it. I have used them only on WinXP.
It has worked flawlessly. I do not konw if this will ever be the case on
FreeDOS. I have never used/tested them in that environment.
- The port has been configured and compiled on WinXP SP3. There is no
guarantee that this may be possible with any other DOS-like OS. Due
to the massive use of long file names it will not be possible to configure
and compile without LFN support. The port has been compiled using gcc520
and bnu225br2.
As usual, all djgpp specific files (diffs, README files, etc.) are stored in
the /arch/djgpp directory. The sources have not been configured due to the
need of absolute paths. Neitherless all scripts have been written to be used
in the build directory called /_build.205.
For further information about GNU Groff please read the info docs and NEWS file.
This is an verbatim extract of the NEWS file (not every change announced may
be available in the DJGPP port):
-------------------------------------------------------------------------------
VERSION 1.22.3
==============
Gxditview
---------
o X11 resources for `gxditview', which were previously installed in
/usr/X11/lib/X11/app-defaults no matter which `prefix' was set, are
now installed in appresdir=$prefix/lib/X11/app-defaults. If
`appresdir' is not a standard X11 resource directory, the environment
variable XFILESEARCHPATH should be set to this path. The standard
default directories depends on the system `libXt'. Common directories
include:
/usr/lib/X11/app-defaults
/usr/share/X11/app-defaults
/etc/X11/app-defaults
Note that if the option `--with-appresdir' is passed to `configure',
the `prefix' will not be added to `appresdir'.
Glilypond
---------
o This new preprocessor (contributed by Bernd Warken) allows embedding of
code for GNU LilyPond (http://www.lilypond.org), a music typesetter. The
data gets automatically processed and embedded as EPS images.
Gperl
-----
o Bernd Warken contributed a new preprocessor to handle Perl code that can
be evaluated and then processed by groff.
Gpinyin
-------
o Another preprocessor from Bernd Warken to pretty-print Pinyin syllables
like `guo2wang2' as `guówáng'.
Pdfroff
-------
o The pdfroff utility script now activates its `--no-toc-relocation' option
by default, unless a request similar to:
.if !\n[PHASE] .tm pdfroff-option:set toc_relocation=enabled
is invoked during input file processing; (`.if !\n[PHASE] ...' ensures
that the effect of the `.tm' request is restricted to the document setup
phase of processing, as pdfroff sets it to 1 or 2 in the output phase,
but leaves it unset in the setup phase).
The bundled `spdf.tmac' macro package, which implicitly activates
`-mpdfmark' for `ms' macro users, ensures that TOC relocation is
appropriately enabled, when the `.TC' macro is invoked.
Macro Packages
--------------
o The -mom macro package now has full support for eqn, pic, and tbl, as well
as captioning and labelling of pdf images and preprocessor output. Lists
of Figures, Equations, and Tables can now be autogenerated. PDF_IMAGE has
a new FRAME option.
o A French introduction to the -me macro package has been added (file
`meintro_fr.me').
o In -mdoc, command %C is now available, providing a city or place
reference.
VERSION 1.22.2
==============
Tbl
---
o The character `#' can now be used as an eqn delimiter within tables.
Eqn
---
o A GNU extension
delim on
has been added to reactivate delimiters which have been disabled with
`delim off'.
VERSION 1.22.1
==============
(There was no release 1.22.)
Groff
-----
o A new option `-j' has been added to call the `chem' preprocessor.
Tbl
---
o Improved line numbering support.
Macro Packages
--------------
o Support for the `refer' preprocessor has been added to the -mm macro
package.
o In -me, the `TH' macro was changed for compatibility with line number
support in tables.
`bl' now works inside of blocks.
The behaviour of centered blocks has been improved.
Line numbering support has been improved.
o The -mom macro package has reached version 2.0, focusing on PDF output
with gropdf (using the new `pdfmom' wrapper script). See the file
`version-2.html' of the -mom documentation for a list of the many changes.
o Some generic Unicode fallback characters (mainly Roman numerals) have been
added.
Gropdf
------
o A new driver for generating PDF output directly, contributed by Deri James
<deri AT chuzzlewit DOT myzen DOT co DOT uk>. Note that this driver is written in Perl,
thus you need a working Perl installation to run this output device.
Pdfmom
------
o A new wrapper around groff that facilitates the production of PDF
documents from files formatted with the -mom macros.
VERSION 1.21
============
Troff
-----
o The new `lsm' request specifies a macro to be invoked when leading spaces
in an input line are encountered (which are removed then). Number
registers `lsn' and `lss' hold the number of removed leading spaces and
the corresponding horizontal space, respectively.
o There is a new warning category `file', enabled by default. The `mso'
request emits warnings in this category when the requested macro file does
not exist.
o The new `class' request assigns a short name to a set of characters
which can be referred to in the `cflags' request. This is especially
useful to control line-breaking and hyphenation rules in CJK languages.
o Three new values for the `cflags' request have been added, which are
needed for proper CJK support.
128 prohibit before but allow break after character
256 prohibit after but allow break before character
512 allow break before and after character
Tbl
---
o A new global option `nowarn' suppresses warnings if tables are longer than
the current line width.
Afmtodit
--------
o New option `-o' to specify the name of the output file.
Macro Packages
--------------
o A new macro `%U' has been added to the mdoc package to indicate a URL
reference within an .Rs/.Re environment.
o Rudimentary support for the Japanese script has been added, most suitable
for man page handling as output by grotty. The file `ja.tmac' contains
the necessary setup to allow line breaks before and after CJK characters
(with proper exceptions). Note, however, that no inter-character spacing
is implemented yet -- this usually causes many warnings about bad line
breaks.
VERSION 1.20.1
==============
A packaging error made it necessary to publish this release. No
user-visible changes.
VERSION 1.20
============
Groff
-----
o 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.
o 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.
o A new environment variable `GROFF_ENCODING' sets the encoding
of input files; it implies command option `-k'.
Troff
-----
o Two new requests `device' and `devicem' have been added which are
equivalents to the \X and \Y escapes, respectively.
o 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.
.als bp AT orig bp
.de bp
. tm before bp
. ie \\n[.br] .bp AT orig
. el 'bp AT orig
. tm after bp
..
o 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).
.fam P
.fzoom CR 1100
.ps 12
Palatino and \f[CR]Courier\f[]
The new number register `.zoom' holds the zoom value of the current font,
in multiples of 1/1000th.
o 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.
o 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.
o 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'.
o A new read-only number register `.O' is available which returns the
current suppression level as set by the `\O' escape.
o 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.
This behaviour is not new, but hasn't been documented before.
Nroff
-----
o Two new command line options `-w' and `-W' are accepted and passed to
groff to enable and disable warning messages, respectively.
Preconv
-------
o 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.
Pic
---
o 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.
o Pic now supports up to 32 macro arguments (and up to 16 on EBCDIC
platforms).
o Heinz-Jürgen Örtel contributed code for two new keywords, `xslanted' and
`yslanted', which can change the shape of boxes into arbitrary
parallelograms.
Tbl
---
o 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.
o To avoid collision with the new `x' specifier, a block formatting macro
must now be selected with specifier letter `m'.
Eqn
---
o 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.
Chem
----
o The preprocessor `chem' was added. `chem' is a roff language to generate
chemical structure diagrams. It generates `pic' output.
Grops
-----
o 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).
For backwards compatibility, the old set of font definition files is still
available; for details please read the man page of grops.
Grotty
------
o \D'p...' is now supported if the polygon consists entirely of horizontal
and vertical lines.
Grohtml
-------
o XHTML support has been added.
o New command line option `-V' (to be used in XHTML mode) to produce an
XHTML validator button.
o New command line option `-y' to produce a right-justified groff signature
at the end of the document (in combination with option `-V').
Gxditview
---------
o Support for keyboard navigation has been improved.
o Similar to other X11 applications, there are now two resource files,
`GXditview' and `GXditview-color'.
Groffer
-------
o `groffer' version 1.* exists now in a shell and a Perl version.
Afmtodit
--------
o New option `-c' to output more font information as comments.
o New option `-k' to suppress output of kerning data.
o New option `-f NAME' to set the internal name of the groff font.
Macro Packages
--------------
o 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:
.TBL cols=2
. TR .TD 1*1 .TD 1*2
. TR .TD 2*1 .TD 2*2
.ETB
Here the same table using a more expanded syntax:
.TBL cols=2
. TR
. TD 1*1
. TD 1*2
. TR
. TD 2*1
. TD 2*2
.ETB
Tables can be nested; `hdtbl' works without a preprocessor so that the
full capability of groff's macro engine is available.
This package currently works with `-Tps' only.
o -mandoc now supports multiple man pages (in either man or mdoc format).
o 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:
groff -ms -mfr foo > foo.ps
Note that latin-9 input encoding is used for French (to support the `oe'
ligature).
o Swedish macro localization (with `-msv') has been added.
o German macro localization (with `-mde' and `-mden' for traditional and
new orthography, respectively) has been added.
o Czech macro localization (with `-mcs') has been added.
Note that latin-2 input encoding is used for Czech.
o A new macro `Dx' has been added to the mdoc package which identifies the
DragonFly OS.
o 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.
o -mtrace has been considerably improved, now showing number and string
register assignments, among other things. See the groff_trace man page
for details.
o 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.
o 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).
o 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.
o A new string, `SN-STYLE', has been added to the ms macros, controlling
the formatting of section numbers in headings defined by `.NH'.
o The new macro package `ptx' provides a template definition for the `.xx'
macro as needed by GNU ptx (for creating permuted indices).
VERSION 1.19.2
==============
Troff
-----
o 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.
o A new read-only, string-valued register `.sty' returns the name of the
current style.
o 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.
o Cyrillic characters have been added to the `utf8' and `html' output
devices.
Pic
---
o 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.
Eqn
---
o The following keywords aren't new but haven't been documented previously:
undef NAME (to undefine a macro)
copy "FILE" (a synonym for `include')
space n (to modify the vertical spacing before and after
an equation)
o The following macros aren't new but haven't been documented previously:
Alpha, ..., Omega (the same as `ALPHA', ..., `OMEGA')
ldots (three dots on the base line)
dollar (a dollar glyph)
o The following keywords have been extended. Again, this isn't new but
hasn't been documented previously:
col n { ... }
lcol n { ... }
rcol n { ... }
ccol n { ... }
pile n { ... }
lpile n { ... }
rpile n { ... }
cpile n { ... } (set vertical spacing between rows to N)
Grohtml
-------
o This device driver has been raised to beta stage; its set of tags should
be stable now.
o New command line option `-s' to set the base point size.
o New command line option `-S' to set the split level while generating
multiple files.
Grotty
------
o Experimental support for zero-width and double-width characters.
Gxditview
---------
o On platforms which have the X Window System this program is now built and
installed automatically.
Xtotroff
--------
o This program to create font definition files for xditview isn't new but
hasn't been installed previously.
Groffer
-------
o A security problem (reported as CAN-2004-0969) has been fixed.
Gdiffmk
-------
o 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.
Pdfroff
-------
o A new wrapper script contributed by Keith Marshall to easily create PDF
documents with groff.
Macro packages
--------------
o ms.tmac
. 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.
. 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.
. The following registers have been added for improving layout control:
PORPHANS
Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which
must be kept together, before any automatic page break.
HORPHANS
Sets number of lines of following paragraph which must be kept with a
heading, defined by `NH' or `SH', before any automatic page break.
GROWPS
Sets the first level of heading (set with `NH') which keeps the
same point size as body text.
PSINCR
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).
. 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.
Please refer to the documentation of the ms package for other, minor
improvements.
o me.tmac
The section type set with the `++' request is available in the `_M'
register. This isn't new but hasn't been documented before.
o www.tmac
The `HR' macro no longer causes an empty line for non-HTML devices.
A new macro `HEAD' has been added to directly add data to the
<head>...</head> block.
New macros `OLS' and `OLE' to start and end an ordered list.
New macros `DLS' and `DLE' to start and end a definition list.
Pdfmark
-------
o A new macro package contributed by Keith Marshall which implements PDF
marks. This is in alpha stage currently.
Miscellaneous
-------------
o 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.
VERSION 1.19.1
==============
Groff
-----
o The argument of the command line option `-I' is now also passed to troff
and grops, specifying a directory to search for files on the command line,
files named in `so' and `psbb' requests, and files named in \X'ps: file'
and \X'ps: import' escapes.
o If option `-V' is used more than once, the commands are both printed
on standard error and run.
Troff
-----
o Two new read-only, string-valued registers `.m' and `.M' return the
name of the current drawing and background color, respectively.
o New read-only register `.U' which is set to 1 if in safer mode and set
to 0 if in unsafe mode.
o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added.
Example use:
groff -Tdvi -mlatin5 my_file > my_file.dvi
Note that some output devices don't support all glyphs of this encoding.
o If the `return' request is called with an argument, it exits twice,
namely the current macro and the macro one level higher. This is
used to define a wrapper macro for `return' in trace.tmac.
o For completeness, two new requests have been added: `dei1' and `ami1'.
They are equivalent to `dei' and `ami', respectively, but the macros
are executed with compatibility mode off (similar to `de1' and `am1').
o New command line option `-I' to specify a directory for files (both
those on the command line and those named in `psbb' requests). This is
also handled by the groff wrapper program.
o Since version 1.19 you can say `.vs 0'. Older versions emit a warning
and convert this to `.vs \n[.V]'.
This hasn't been documented properly. Note that `.vs 0' isn't saved in a
diversion since it doesn't result in vertical motion.
Pic
---
o Dashed and dotted ellipses have been implemented.
Tbl
---
o New specifier `x' to make tbl call a user-defined macro on a table
cell. Patch by Heinz-Jürgen Oertel <hj DOT oertel AT surfeu DOT de>.
Grap2graph
----------
o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>. It
converts a grap diagram into a cropped image. Since it uses gs and the
PNM library, virtually all graphics formats are available for output.
[Note that the grap program itself isn't part of the groff package;
see the file MORE.STUFF how to obtain grap.]
Grohtml
-------
o New option `-j' to emit output split into multiple files.
Grops
-----
o New command line option `-I' to specify a directory to search for files
on the command line and files named in \X'ps: import' and \X'ps: file'
escapes. This is also handled by the groff wrapper program.
o The default value for the `broken' keyword in the DESC file is now 0.
Grolj4
------
o A new man page `lj4_font(5)' documents how fonts are accessed with
grolj4.
o The built-in fonts for LJ4 and newer PCL 5 devices have been completely
revised, mainly to access as much glyphs as possible. The provided
metric files should be compatible with recent PCL 5 printers also.
Additionally, font description files have been added for the Arial and
Times New Roman family, the MS symbol, and Wingdings fonts.
Afmtodit
--------
o New option `-x' to prevent use of built-in Adobe Glyph List.
Hpftodit
--------
o Completely revised to handle HP TrueType metric files also. See the
hpftodit manual page for more details.
Groffer
-------
o This version is a rewrite of groffer in many parts, but it is kept in
the old single script style.
New options: --text, --mode text, --tty-viewer, --X, --mode X,
--X-viewer, --html, --mode html, --html-view, --apropos-data,
--apropos-devel, --apropos-progs.
New documentation file: README_SH.
Enhancement of the configuration files and the `apropos' handling.
Macro Packages
--------------
o www.tmac: New macro `JOBNAME' to split output into multiple files.
o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY
section.
VERSION 1.19
============
Troff
-----
o Input encoding files for latin-9 (a.k.a. latin-0 and ISO 8859-15) and
latin-2 (ISO 8859-2) have been added. Example use:
groff -Tdvi -mlatin9 my_file > my_file.dvi
You still need proper fonts with the necessary glyphs. Out of the box,
the groff package supports latin-9 only for -Tps, -Tdvi, and -Tutf8,
and latin-2 only for -Tdvi and -Tutf8.
o Composite glyphs are now supported. To do this, a subset of the Adobe
Glyph List (AGL) Algorithm as described in
http://partners.adobe.com/public/developer/opentype/index_glyph.html
is used to construct glyph names based on Unicode character codes. The
existing groff glyph names are frozen; no glyph names which can't be
constructed algorithmically will be added in the future.
The \[...] escape sequence has been extended to specify multiple glyph
components. Example:
\[A ho]
this accesses a glyph with the name `u0041_0328'.
Some groff glyphs which are useful as composites map to `wrong' Unicode
code points. For example, `ho' maps to U+02DB which is a spacing
ogonek, whereas a non-spacing ogonek U+0328 is needed for composite
glyphs. The new request
.composite from to
changes the mapping while a composite glyph name is constructed.
To make \[A ho] yield the expected result,
.composite ho u0328
is needed. [The new file `composite.tmac' loaded at start-up already
contains proper calls to `.composite'.]
Please refer to the info pages of groff and to the groff_char man page
for more details.
o A new request `fschar' has been added to define font-specific fallback
characters. They are searched after the list of fonts declared with the
`fspecial' request but before the list of fonts declared with `special'.
o Fallback characters defined with `fschar' can be removed with the
new `rfschar' request.
o A new request `schar' has been added to define global fallback
characters. They are searched after the list of fonts declared with the
`special' request but before the already mounted special fonts.
o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the current
point horizontally. Despite of being silly, this change has been
reverted for backwards compatibility. Consequently, the intermediate
output command `Df' also moves the position horizontally again.
\D'f ...' is deprecated since it depends on the horizontal resolution of
the output device (given with the `hor' parameter in the DESC file).
Use the new \D'Fg ...' escape instead.
o For orthogonality, new \D subcommands to change the fill color are
available:
\D'Fr ...' (rgb)
\D'Fc ...' (cmy)
\D'Fg ...' (gray)
\D'Fk ...' (cmyk)
\D'Fd' (default color)
The arguments are the same as with the `defcolor' request. The current
position is *not* changed.
o The values set with \H and \S are now available in number registers
\n[.height] and \n[.slant], respectively.
o The `.pe' number register isn't new but hasn't been documented before.
It is set to 1 during a page ejection caused by the `bp' request.
o The new glyph symbol `tno' is a textual variant of `no'.
o The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL.
(Well, it is not really new since it has been previously supported by
grolj4.) The mapping for both the dvi and lj4 symbol font has been
changed accordingly so that Greek small letter epsilon, `*e', has the
same glyph shape as with other devices.
Grops
-----
o The font `freeeuro.pfa' has been added to provide various default glyph
shapes for `eu' and `Eu'.
o It is now possible to access all glyphs in a Type 1 font, not only 256
(provided the font file created by afmtodit has proper entries). grops
constructs additional encoding vectors on the fly if necessary.
o The paper size is now emitted via the %%DocumentMedia and PageSize
mechanisms so that it is no longer required to tell `gv' or `ps2pdf'
about the paper size. The `broken' flag value 16 omits this feature
(the used PostScript command `setpagedevice' is a LanguageLevel 2
extension) -- if you intend to further process grops output to get an
encapsulated PS (EPS) file you must also use this option.
Patch by Egil Kvaleberg <egil AT kvaleberg DOT no>.
o Non-slanted PostScript metrics have been changed again; they no longer
contain negative left italic correction values. This assures correct
spacing with eqn.
Grodvi
------
o The font cmtex10 has been added as the special font `SC' to the DVI fonts.
It is used as a font-specific special font for CW and CWI.
o New options -l and -p to set landscape orientation and the paper size.
grodvi now emits a `papersize' special which is understood by DVI drivers
like dvips.
Consequently, the DESC file should contain a `papersize' keyword.
o The glyph shapes for \[*f] and \[*e] have been exchanged with \[+f] and
\[+e], respectively, to be in sync with all other devices.
o Glyphs \[HE] and \[DI] have been replaced with \[u2662] and \[u2661],
respectively, since the former two glyphs have a black (filled) shape
which grodvi doesn't provide by default (it never has actually).
Grolj4
------
o The glyphs \[*e] and \[+e] have been exchanged to be in sync with
all other devices.
o The glyph \[~=] is now called \[|=]. Similar to other devices, \[~=]
is now another name for glyph \[~~].
Grotty
------
o New option `-r'. It is similar to the -i option except it tells grotty to
use the `reverse video' attribute to render italic fonts.
Pic
---
o New command `figname' to set the name of a picture's output box in TeX
mode.
Refer
-----
o The environment variable `REFER' to override the name of the default
database isn't new but hasn't been documented before.
Soelim
------
o New option `-r' to avoid emission of `.lf' lines.
o New option `-t' to emit TeX comment lines (giving current file and the
line number) instead of `.lf' lines.
Afmtodit
--------
o Unencoded glyphs in an AFM file are output also (since grops can now emit
multiple encoding vectors for a single font).
o New option `-m' to prevent negative left italic correction values.
o The mapping and encoding file together with file `DESC' are now searched
in the default font directory also. Please refer to the man page of
afmtodit for more details.
Macro Packages
--------------
o Larry Kollar <kollar AT alltel DOT net> and others made the man macros more
customizable.
. New command line options -rFT, -rIN, and -rSN to set the vertical
location of the footer line, the body text indentation, and the
sub-subheading indentation.
. New command line option -rHY (similar to the ms macros) to control
hyphenation.
. New macros `.PT' and `.BT' to print the header and footer strings.
They can be replaced with a customized version in `man.local'.
. The string `HF' now holds the typeface to print headings and
subheadings.
. Similar to the ms macros, the LT register now defaults to LL if not
explicitly specified on the command line.
o troff's start-up file `troffrc' now includes `papersize.tmac' to set
the paper size with the command line option `-dpaper=<size>'.
Possible values for `<size>' are the same as the predefined `papersize'
values in the DESC file (only lowercase; see the groff_font man page)
except a7-d7. An appended `l' (ell) character denotes landscape
orientation. Examples: `a4', `c3l', `letterl'.
Most output drivers need additional command line switches `-p' and
`-l' to override the default paper length and orientation as set in
the driver specific DESC file.
For example, use the following for PS output on A4 paper in landscape
orientation:
groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
VERSION 1.18.1
==============
Troff
-----
o The non-slanted PostScript font definition files have been regenerated to
include left and right italic correction values. Applying those to a
glyph (this is, prepending the glyph with `\,' and appending `\/' to the
glyph) sets the glyph width to the real value given by the horizontal
bounding box values. Without those escapes, the advance width for the
particular glyph is used (which can differ considerably).
Most users will neither need this feature nor notice a difference in
existing documents (provided \, and \/ is used as advertised, namely for
italic fonts only); its main goal is to improve image generation with
grohtml.
This is an experimental change, and feedback is welcome.
Tbl
---
o Added global option `nospaces' to ignore leading and trailing spaces in
data items.
Grolbp
------
o The option -w (--linewidth) has been added (similar to other device
drivers) to set the default line width.
Grn
---
o Support for b-spline and Bezier curves has been added.
Groffer
-------
o New option `--shell' to select the shell under which groffer shall run.
Macro Packages
--------------
o The string `Am' (producing an ampersand) has been added to mdoc for
compatibility with NetBSD.
o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit)
instead.
o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal
and vertical movements; please refer to contrib/mom/NEWS for more
details.
o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers.
Miscellaneous
-------------
o The `papersize' keyword in the DESC file now accepts multiple arguments.
It is scanned from left to the right, and the first valid argument is
used. This makes it possible to provide a fallback paper size.
Example:
papersize /etc/papersize a4
o A local font directory has been prepended to the default font path; it
defaults to /usr/local/share/groff/site-font. Similar to the normal
font searching process, files must be placed into a devXXX subdirectory,
e.g.
/usr/local/share/groff/site-font/devps/FOO
for a PostScript font definition file FOO.
VERSION 1.18
============
***************************************************************************
* *
* PLEASE READ THE CHANGES BELOW REGARDING GROTTY, GROFF'S TTY FRONTEND. *
* *
***************************************************************************
Troff
-----
o Color support has been added to troff and pic (and to the device drivers
grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will
follow). A new function `defcolor' defines colors; the escape sequence
`\m' sets the drawing color, the escape sequence `\M' specifies the
background color for closed objects created with \D'...' commands.
`\m[]' and `\M[]' switch back to the previous color. `\m' and `\M'
correspond to the new troff output command sets starting with `m' and
`DF'. The device-specific default color is called `default' and can't be
redefined.
Use the `color' request to toggle the usage of colors (default is on); the
read-only register `.color' is 0 if colors are not active, and non-zero
otherwise.
The old `Df' output command is mapped onto `DFg'; all color output
commands don't change the current font position (consequently, `Df'
doesn't either).
Outputting color can be disabled in troff and groff with the option -c
(it is always disabled in compatibility mode). See the section on grotty
for the GROFF_NO_SGR environment variable also.
For defining color components as fractions between 0 and 1, a new scaling
indicator `f' has been introduced: 1f = 65536u. For testing whether a
color is defined (with .if and .ie), a new conditional operator `m' is
available.
More details can be found in the groff_diff.7 manual page and in
groff.texinfo.
o Similar to \m and \M, \f[] switches back to the previous font. \fP
(and \f[P]) is still valid for backwards compatibility.
o The new escape \F is the same as `.fam'; \F[] switches back to previous
family -- \F[P] selects family `P'.
o Two new glyph symbols are available: `eu' is the official Euro symbol;
`Eu' is a font-specific glyph variant.
o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of
`+-', `di', and `mu', respectively.
o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has
got the troff glyph name `mc'.
o -Tutf8 is now available on EBCDIC hosts.
o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...].
Example:
.ds xxx This is a \\$1 test.
\*[xxx nice]
o It is now possible to have whitespace between the first and second dot (or
the name of the ending macro) to end a macro definition. Example:
.de !
..
.
.de foo
. nop Hello, I'm `foo'.
. nop I will now define `bar'.
. de bar !
. nop Hello, I'm `bar'.
. !
..
o `.fn' is a new string-valued register which returns the (internal) real
font name; styles and families are properly concatenated.
o Three new read/write registers `seconds', `minutes', and `hours' contain
the current time, set at start-up of troff. Use the `af' request to
control their output format.
o The new request `fchar' can be used to provide fallback characters. It
has the same syntax as the `char' request; the only difference is that a
character defined with `.char' hides the glyph with the same name in the
current font, whereas a character defined with `.fchar' is checked only if
the particular glyph isn't found in the current font. This test happens
before checking special fonts.
o In analogy to the `tmc' request, `.writec' is the same as `.write' but
doesn't emit a final newline.
o The new request `itc' is a variant of `.it' for which a line interrupted
with \c counts as one input line.
o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but
with compatibility mode disabled during expansion of strings defined by
them.
o The syntax of the `substring' request has been changed: The first
character in a string now has index 0, the last character has index -1.
Note that this is an incompatible change.
o To emit strings directly to the intermediate output, a new `output'
request has been added; it is similar to `\!' used at the top level.
o `.hpf' has been extended. It can now handle most TeX hyphenation
pattern files without modification. To do that, the commands \patterns,
\hyphenation, and \endinput are recognized. Please refer to groff_diff.7
for more information.
o `hpfcode' is a new request to provide an input encoding mapping for the
`hpf' request.
o The new request `hpfa' appends hyphenation patterns (`hpf' replaces
already existing patterns).
o A new request `ami' (append macro indirect) has been added. The first and
second parameter of `ami' are taken from string registers rather than
directly; this very special request is needed to make `trace.tmac'
independent from the escape character (which might even be disabled).
o The new request `sizes' is similar to the `sizes' command in DESC files.
It expects the same syntax; the data must be on a single line, and the
final `0' can be omitted.
o `trin' (translate input) is a new request which is similar to `tr' with
the exception that the `asciify' request uses the character code (if
any) before the character translation. Example:
.trin ax
.di xxx
a
.br
.di
.xxx
.trin aa
.asciify xxx
.xxx
The result is `x a'. Using `tr', the result would be `x x'.
o The request `pvs' isn't new, but hasn't been documented before. It
adds vertical space after a line has been output. This makes it an
alternative to the `ls' request to produce double-spaced documents.
The read-only register `.pvs' holds the current amount of the
post-vertical line space.
o For compatibility with plan 9's troff, multiple `pi' requests are
supported:
.pi foo
.pi bar
is now equivalent to
.pi foo | bar
o A new escape sequence `\O' is available to disable and enable glyph
output. Please see groff_diff.7 and groff.texinfo for more details.
o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X;
they are ignored now. Additionally `\ ' and `\~' are converted to
single space characters.
o The default tab distance in nroff mode is now 0.8i to be compatible
with UNIX troff.
o Using the latin-1 input character 0xAD (soft hyphen) for the `shc'
request was a bad idea. Instead, it is now translated to `\%', and
the default hyphenation character is again \[hy]. Note that the glyph
\[shc] is not useful for typographic purposes; it only exists to have
glyph names for all latin-1 characters.
Macro Packages
--------------
o Peter Schaffter <df191 AT ncf DOT ca> has contributed a new major macro package
called `mom', mainly for non-scientific writers, which takes care of
many typographic issues. It comes with a complete reference (in HTML
format) and some examples. `mom' has been designed to format documents
for PostScript output only.
o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
the man macros for compatibility with older BSD releases.
o Both the man and mdoc macro packages now use the LL and LT registers for
setting the line and title length, respectively (similar to those
registers in the ms macro package). If not set on the command line or
in a macro file loaded before the macro package itself, they default to
78n in nroff mode and 6.5i in troff mode.
o The `-xwidth' specifier in the mdoc macro package has been removed. Its
functionality is now integrated directly into `-width'. Similarly,
`-column' has been extended to provide this functionality also.
o A new macro `Ex' has been added to the mdoc macro package to document an
exit status.
o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is
now automatically loaded for -Tdvi), using a dvips special to load the EPS
file.
o The trace.tmac package now traces calls to `am' also. Additionally, it
works in compatibility mode.
o `troff.1' has been split. Differences to UNIX troff are now documented
in the new man page `groff_diff.7'.
o `groff_mwww.7' has been renamed to `groff_www.7'. The file mwww.tmac
has been removed.
o `groff_ms.7' has been completely rewritten. It now contains a complete
reference to the ms macros.
o `groff_trace.7' documents the trace macro package.
o Changes in www.tmac:
Note that HTML support is still in alpha change, so it is rather likely
that both macro names and macro syntax will change. Some of the macros
mentioned below aren't really new but haven't been documented properly
before.
The following macros have been renamed:
MAILTO -> MTO
IMAGE -> IMG
LINE -> HR
For consistency, the macros `URL', `FTL', and `MTO' now all have the
address as the first parameter followed by the description.
By default, grohtml generates links to all section headings at the top
of the document. Use the new `LK' macro to specify a different place.
For specifying the background color and a background image, use the
new macros `BCL' and `BGIMG', respectively.
The macro `NHR' has been added; it suppresses the generation of top and
bottom rules which grohtml emits by default.
The new macro `HX' determines the cut-off point for automatic link
generation to headings.
The image position parameter names in `IMG' have been changed to `-L',
`-R', and `-C'.
New macro `PIMG' for inclusion of a PNG image (it automatically
converts it into an EPS file if not -Thtml is used).
New macro `MPIMG' for putting a PNG image into the left or right margin
(it automatically converts it into an EPS file if not -Thtml is used).
New macros `HnS', `HnE' to start and end a header line block.
New macro `DC' to produce dropcap characters.
New macro `HTL' to generate an HTML title line only but no H1 heading.
New macros `ULS' and `ULE' to start and end an unordered list. The new
macro `LI' inserts a list item.
Groff
-----
o The new command line option `-c' disables color output (which is always
disabled in compatibility mode).
Nroff
-----
o Two new command line options `-c' and `-C'; the former passes `-c' to
grotty (switching to the old output scheme); the latter passes `-C' to
groff (enabling compatibility mode).
Pic
---
o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or
`outlined'), and `shaded' are available. `outline' sets the color of the
outline, `shaded' the fill color, and `color' sets both. Example:
circle shaded "green" outline "black" ;
Filled arrows always use the outline color for filling.
Color support for TeX output is not implemented yet.
Pic2graph
---------
o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>. It
converts a PIC diagram into a cropped image. Since it uses gs and the PNM
library, virtually all graphics formats are available for output.
Eqn2graph
---------
o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>. It
converts an EQN diagram into a cropped image. Since it uses gs and the PNM
library, virtually all graphics formats are available for output.
Groffer
-------
o A new script contributed by Bernd Warken <bwarken AT mayn DOT de>. It displays
groff files and man pages on X and tty, taking care of most parameters
automatically.
Grog
----
o Documents using the mom macro package are recognized.
Grops
-----
o Color support has been added.
o A new option `-p' is available to select the output paper size. It has
the same syntax as the new `papersize' keyword in the DESC file.
Grodvi
------
o By default, font sizes are now available in the range 5-10000pt, similar
to PS fonts. If you want the old behaviour (i.e., font sizes at discrete
values only), insert the following at the start of your document:
.if '\*[.T]'dvi' \
. sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \
1728 1800 2000 2074 2200 2400 2488 2800 3600
o A new font file HBI (using cmssbxo10; this is slanted sans serif bold
extended) has been added.
o Two font families are now available: `T' and `H'.
o EC and TC fonts have been integrated. Use `-mec' (calling the file
ec.tmac) to switch to them. Those fonts give a much better coverage of
the symbols defined by groff than the CM fonts.
Note that ec.tmac must be called before any language-specific files; it
doesn't take care of hcode values.
o Color support has been added. For drawing commands, colors are translated
to gray values currently.
Grotty
------
o Color support has been added, using the SGR (ISO 6429, sometimes called
ANSI color) escape sequences.
o SGR escape sequences are now used by default for underlining and bold
printing also, no longer using the backspace character trick. To revert
to the old behaviour, use the `-c' switch.
Note that you have to use the `-R' option of `less' to make SGR escapes
display correctly. On the other hand, terminal programs and consoles like
`xterm' which support SGR sequences natively can directly display the
output of grotty. Consequently, the options `-b', `-B', `-u', and `-U'
work only in combination with `-c' and are ignored silently otherwise.
For the `man' program, it may be necessary to add the `-R' option of
`less' to the $PAGER environment variable (or $MANPAGER, depending on the
used `man' program); alternatively, you can use `man's `-P' option (or
adapt its configuration file accordingly). See man(1) for more details.
o If the environment variable GROFF_NO_SGR is set, SGR output is disabled,
reverting to the old behaviour.
o A new special \X'tty: sgr n' has been added; if n is non-zero or missing,
enable SGR output (the default).
o If the new option `-i' is used (only in SGR mode), grotty sends escape
sequences to set the italic font attribute instead of the underline
attribute for italic fonts. Note that many terminals don't have support
for this (including xterm).
Grohtml
-------
o Color support for glyphs has been added.
o New option `-h' to select the style of headings in HTML output.
o New option `-b' to set the background colour to white.
o New options `-a' and `-g' to control the number of bits for anti-aliasing
used for text and graphics, respectively. Default value is 4; 0 means
no anti-aliasing.
o groff character/glyph entities now map onto HTML 4 character entities.
Grolbp
------
o Valid paper sizes are now specified as with the new `papersize' keyword
in the DESC file. Specifically, the old custom paper type format
`custAAAxBBB' is no longer supported.
Miscellaneous
-------------
o A new manual page `ditroff.7' is available.
o The groff texinfo manual is installed now, together with a bunch
of examples.
o A new keyword `papersize' has been added to the DESC file format. Its
argument is either
. a predefined paper format (e.g. `A4' or `letter')
. a file name pointing to a file which must contain a paper size
specification in its first line (e.g. `/etc/papersize')
. a custom paper size definition like `35c,4i'
See groff_font(5) for more details. This keyword only affects the
physical dimensions of the output medium; grops, grolj4, and grolbp use it
currently. troff completely ignores it.
VERSION 1.17.2
==============
This is major bug-fixing release which should replace 1.17.1.
Troff
-----
o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter
gives the horizontal image location (left, centered, or right), and the
optional 3rd and 4th parameter the image dimensions.
VERSION 1.17.1
==============
This is mainly a bug-fixing release.
Troff
-----
o Two new requests `de1' and `am1' which are similar to `de' and `am' but
with compatibility mode disabled during expansion of macros defined by
them.
o Added request `brp'. This is the same as `\p'.
o Similar to other versions of troff, the `ns' request now works in all
diversions, not only in the top-level one.
o New read-only number register `.ns'. Returns 1 if in no-space mode,
0 otherwise.
Nroff
-----
o Options -p (pic) and -t (tbl) added.
o The environment variable GROFF_BIN_PATH is now checked before PATH for
finding groff.
Grohtml
-------
o New option `-D dir' to specify a directory in which all images are placed.
o New option `-I stem' to specify an image name stame. If not given,
`grohtml-XXX' is used (`XXX' is the process ID).
VERSION 1.17
============
Groff
-----
o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'. The
old behaviour has been changed to overcome problems with platforms which
have an 8+3 file name limit, and platforms which have other versions of
troff installed also. Additionally, all macro files have been renamed
using the latter scheme to avoid 8+3 name clashes.
o The new environment variable GROFF_BIN_PATH is checked for programs groff
is calling (preprocessors, troff, and output devices) before PATH. If not
set, it defaults to the directory where the groff binary is located.
Previously, it was PATH only. The nroff script only uses GROFF_BIN_PATH
to find the groff binary but passes both the GROFF_BIN_PATH and PATH
environment variables to groff.
Troff
-----
o The mdoc package has been completely rewritten, using the full power of
GNU troff to remove limitations of Unix troff (which is no longer
supported). Most important changes are:
. No argument limit
. Almost all macros are parsed and callable (if it makes sense)
. `.Lb': prints library names
. `.Nm <punctuation>' now works as expected; `.Nm "" <punctuation>' has
been withdrawn
. Updated `.St' command
. `.Fx': prints FreeBSD
. `.Ox': prints OpenBSD
. `.Bsx': prints BSD/OS
. `.Brq', `.Bro', `.Brc': brace enclosure macros
. `.Bd -centered': center lines
. `.Bl -xwidth <string>': interpret <string> and use the resulting width
. Support for double-sided printing (-rD1 command line switch)
. Support for 11pt and 12pt document sizes (-rS11, -rS12 command line
switches)
`groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely
documents the mdoc package.
Great care has been taken to assure backwards compatibility. If you
encounter any abnormal results, please report them to bug-groff AT gnu DOT org.
o A new command line option for the `man' macros (similar to the `mdoc'
package) has been implemented: `-rcR=1' (now the default in nroff mode)
produces one single, very long page instead of multiple pages. `-rcR=0'
deactivates it.
o The `return' request has been added to return immediately from a macro.
o A new request `nop' (no operation) has been added which is similar to
`if 1'. For example,
.if t \{\
Hallo!
.\}
can now be written as
.if t \{\
. nop Hallo!
.\}
o `box' and `boxa' are two new requests which behave similarly to `di' and
`da' but don't include a partially filled line (which is restored after
ending the diversion).
o The `asciify' request has been extended to `unformat' space characters
and some other escape sequences also.
`\ ' is no longer unformatted as a space but remains an unpaddable,
unbreakable space character.
o The new `unformat' request is similar to `asciify' but only handles space
characters and tabs specially if the diversion is reread, retaining font
information. This makes it possible to reformat diversions; for example
the following
.ll 3i
.
a01 a02 a03 a04 a05 a06 a07 a08 a09 a10.
.
.box box1
.ev 1
.nf
\f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P]
.br
.ev
.box
.
c01 c02 c03 c04 c05 c06 c07 c08 c09 c10.
.
.unformat box1
.box1
gives
a01 a02 a03 a04 a05 a06 a07
a08 a09 a10. c01 c02 c03 c04
c05 c06 c07 c08 c09 c10. b01
b02 b03 b04 b05 b06 b07 b08
b09 b10.
Without the `unformat' request, space characters are converted to word
space nodes which are no longer stretchable, and the result would be
a01 a02 a03 a04 a05 a06 a07
a08 a09 a10. c01 c02 c03 c04
c05 c06 c07 c08 c09 c10. b01

b09 b10.
o The new request `linetabs' controls the `line-tabs' mode. In line-tabs
mode, tab distances are computed relative to the (current) output line.
Otherwise they are taken relative to the input line. For example, the
following
.ds x a\t\c
.ds y b\t\c
.ds z c
.ta 1i 3i
\*x
\*y
\*z
yields
a b c
In line-tabs mode, the same code gives
a b c
The new read-only number register `.linetabs' returns 1 if in line-tabs
mode, and 0 otherwise.
o Two new requests `tm1' and `tmc' have been added to improve writing
messages to the terminal. `tm1' is similar to `tm' but allows leading
whitespace. `tmc' is similar to `tm1' but doesn't emit a final newline.
o For compatibility with sqtroff, the request `output' has been added.
The behaviour is similar to `\!' at the top-level, that is, it directly
inserts its argument into the intermediate output format. The syntax
is similar to .tm1, allowing leading whitespace.
o The new `spreadwarn' request makes troff warn if spaces in an output
line are widened by a given limit or more.
o Use `warnscale' to change the scaling indicator troff uses for
warning messages.
o A new request `dei' (define indirect) has been added. The first and
second parameter of `dei' are taken from string registers rather than
directly; this very special request is needed to make `trace.tmac'
independent from the escape character (which might even be disabled).
o It is now possible to save and restore the escape character with two new
requests `ecs' and `ecr'.
o The new escape sequence \B'...' is an analogon to `\A': If the string
within the delimiters is a valid numeric expression, return character `1',
and `0' otherwise.
o The new escape sequence `\:' inserts a zero-width break point. This is
similar to `\%' but without a soft hyphen character.
o The `tr' request can now map characters onto `\~'.
o Calling the `fam' request without an argument switches back to the
previous font family.
o The new read-only register `.int' is set to a positive value if the last
output line is interrupted (i.e., if the input line contains `\c').
o The `writem' request is not new, but hasn't been documented before. This
is similar to `write' but instead of a string the contents of a given
macro or string is written to a stream.
o The read/write number register `hp' to get/set the current horizontal
position relative to the input line isn't new but hasn't been documented
properly before.
o `\X' and `\Y' are now transparent for end-of-sentence recognition.
o The `cu' request in nroff mode now works as documented (i.e., it
underlines spaces also).
Grog
----
o The grog script now works in non-compatibility mode also (which is the
default). As usual, use the `-C' option to activate compatibility mode.
Grops
-----
o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has
been added to select a different prologue file.
o The effect of the former `-mpsnew' option to access more Type 1 characters
is now the default and no longer available. To get the old behaviour
(i.e., emulation of some glyphs by composition) use `-mpsold'.
Miscellaneous
-------------
o For security reasons the following changes have been done:
. The tmac.safer file has been replaced with a built-in solution; .open,
.opena, .pso, .sy, and .pi are completely disabled in safer mode (which
is the default); to enable these requests the `-U' command line flag
must be used.
. Files specified with the .mso request or given with the `-m' command
line option, and hyphenation patterns loaded with `.hpf' are no longer
searched in the current directory by default (besides the usual tmac
path). Instead, the home directory is used. To add the current
directory, either use the `-U' or `-M' command line option or set the
GROFF_TMAC_PATH environment variable to an appropriate value.
. troffrc, troffrc-end, and eqnrc are neither searched in the current nor
in the home directory (even if -U is given). Use -M or GROFF_TMAC_PATH
to change that.
. Similarly, the current directory is no longer part of the font path.
Use the `-F' command line option or the GROFF_FONT_PATH environment
variable if you really need the current directory.
o groff now installs its data files into /usr/local/share/groff/<version> by
default, following the GNU standard. Additionally, a local tmac directory
(by default /usr/local/share/groff/site-tmac) is scanned before the
standard tmac directory. Wrapper files for system-specific macro packages
(if necessary) are put into /usr/local/lib/groff/site-tmac; this directory
is searched before the local tmac directory.
o All programs now have option `-v' to show the version number; they exit
immediately afterwards, following the GNU standards. Additionally,
`--version' and `--help' have been added, doing the obvious actions.
