54 is a typesetting package which reads plain text mixed with
55 formatting commands and produces formatted output.
56 Groff now supports HTML.

84 This is the GNU groff document formatting system.
85 The version number is given in the file VERSION.
87 Included in this release are implementations of troff, pic, eqn, tbl, refer,
88 the -man macros and the -ms macros, and drivers for PostScript, TeX dvi
89 format, HP LaserJet 4 printers, HTML format (still alpha), and
90 typewriter-like devices.
91 Also included is a modified version of the Berkeley -me macros, an enhanced
92 version of the X11 xditview previewer, and an implementation of the -mm
94 .MTO jh@\:axis.se "J\(:orgen H\(:agg" .
96 See the file INSTALL for installation instructions.
97 You will require a C++ compiler.
99 The file NEWS describes recent user-visible changes to groff.
101 Groff is free software.
102 See the file COPYING for copying permission.
104 The file PROBLEMS describes various problems that have been encountered in
105 compiling, installing, and running groff.
107 For the moment, the documentation assumes that you are already familiar with
108 the Unix versions of troff, -man, -ms and the preprocessors.
110 The most recent released version of groff is always available by anonymous
111 ftp from ftp.gnu.org in the directory pub/\:gnu/\:groff.
113 A CVS repository is now available, containing the current development
115 You can access it with the commands:
120 export CVSROOT=:pserver:anoncvs@anoncvs.ffii.org:/var/cvs
127 (if the prompt for the password appears, just press the enter key).
128 After a successful login you no longer need the first two commands; an
129 update of a checked out repository should be done with:
137 Please read the info pages of cvs for further details.
139 Alternatively, you can download snapshots (which are updated twice a day)
141 .URL ftp://\:ftp.ffii.org/\:pub/\:groff/\:devel/\:groff-current.tar.gz here
142 or a diff file relative to the latest official groff release as:
146 ftp://ftp.ffii.org/pub/groff/devel/groff-[version]-current.diff.gz
150 Please report bugs using the form in the file BUG-REPORT; the idea of this
151 is to make sure that FSF has all the information it needs to fix the bug.
152 At the very least, read the BUG-REPORT form and make sure that you supply
153 all the information that it asks for.
154 Even if you are not sure that something is a bug, report it using
155 BUG-REPORT: this will enable us to determine whether it really is a bug or
158 Three mailing lists are available:

166 .MTO groff@gnu.org groff@gnu.org

170 .MTO groff-commit@ffii.org groff-commit@ffii.org
171 a read-only list showing logs of commitments to the CVS repository
174 Note that groff@gnu.org is an alias for
175 .MTO groff@\:ffii.org groff@\:ffii.org ;
176 you must be subscribed to the `groff' and `groff-commit' lists to send mails.
178 To subscribe, send e-mail to [list]-request@[domain] (example:

196 This section describes recent user-visible changes in groff. Bug
197 fixes are not described. There are more details in the man pages.
205 Color support has been added to troff and pic (and to two device drivers,
206 grops and grohtml -- other preprocessors and drivers will follow). A new
207 function `defcolor' defines colors; the escape sequence `\em' sets the
208 drawing color, the escape sequence `\eM' specifies the background color for
209 closed objects created with \eD'...' commands. Similar to fonts, `\emP' and
210 `\eMP' switch back to the previous color. `\em' and `\eM' correspond to the
211 new troff output commands `m' and `DF'.
213 Outputting color can be disabled in troff and groff with the option -c
214 (it is always disabled in compatibility mode).
216 For defining color components as fractions between 0 and 1, a new scaling
217 indicator `f' has been defined: 1f = 65536u. For testing whether a color
218 is defined (with .if and .ie), a new conditional operator `m' is
221 More details can be found in the troff manual page.
224 It is now possible to have whitespace between the first and second dot (or
225 the name of the ending macro) to end a macro definition. Example:
233 \&. nop Hello, I'm `foo'.
234 \&. nop I will now define `bar'.
236 \&. nop Hello, I'm `bar'.
244 `.fn' is a new string-valued register which returns the (internal) real
245 font name; styles and families are properly concatenated.
248 The new request `fchar' can be used to provide fallback characters. Its
249 syntax is the same as the `char' request; the only difference is that a
250 character defined with `.char' hides the glyph with the same name in the
251 current font, whereas a character defined with `.fchar' is checked only if
252 the particular glyph isn't found in the current font. This test happens
253 before checking special fonts.
256 The new request `itc' is a variant of `.it' for which a line interrupted
257 with \ec counts as one input line.
260 A new escape sequence `\eO' is available (mainly for internal use with
261 grohtml). Please see groff_diff.man and groff.texinfo for more details.
264 Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
265 the man macros for compatibility with older BSD releases.
268 The `-xwidth' specifier in the mdoc macro package has been removed. Its
269 functionality is now integrated directly into `-width'. Similarly,
270 `-column' has been extended to has this functionality also.
273 A new macro `Ex' has been added to the mdoc macro package to document an
277 `troff.man' has been split. Differences to UNIX troff are now documented
278 in the new man page `groff_diff.man'.
281 groff_mwww.man' has been renamed to `groff_www.man'. The file mwww.tmac
285 The macro `NO-AUTO-RULE' has been added to www.tmac; it suppresses the
286 generation of top and bottom rules which grohtml emits by default.
295 The new command line `-c' disables color output (which is always disabled
296 in compatibility mode).
305 New keywords `color' (or `colour', `colored', `coloured'), `outline' (or
306 `outlined'), and `shaded' are available. `outline' sets the color of the
307 outline, `shaded' the fill color, and `color' sets both. Example:
309 \fCcircle shaded "green" outline "black" ;\fP
311 Color support for TeX output is not implemented yet.
320 A new script contributed by Eric S. Raymond <esr@thyrsus.com>. It
321 converts a PIC diagram into a cropped image. Since it uses gs and the PNM
322 library, virtually all graphics formats are available for output.
331 Color support has been added.
340 Color support for glyphs has been added.
343 New option `\fC-h\fP' to select the style of headings in HTML output.
352 A new manual page `\fCditroff.7\fP' is available.
