NAME
groff_www - groff macros for authoring web pages
SYNOPSIS
groff -mwww [ options ] file ...
DESCRIPTION
This manual page describes the GNU -mwww macro package,
which is part of the groff document formatting system. The manual page is very a basic guide, and the html device driver (grohtml) has been completely rewritten but still remains as in an alpha state. It has been included into the distribution so that a lot of people have a chance to test it. Note that this macro file will be automatically called(via the troffrc file) if you use -Thtml.
To see the hyperlinks in action, please format this man page with the grohtml device. Here is a summary of the functions found in this macro set..JOBNAME split output into multiple files
.HX automatic heading level cut off;$1 point for sections/headers
.BCL specify colours on a web page .BGIMG specify background image .URL create a url using two parameters .FTP create an ftp reference .MTO create a html email address .FTP create an ftp reference .TAG generate an html name .IMG include an image file .PIMG include png image .MPIMG place png on the margin and wrap text around it .HnS begin heading .HnE end heading .LK emit automatically collected links. .HR produce a horizontal rule .NHR suppress automatic generation of rules. .HTL only generate HTML title .HEAD add data to block .ULS unorder list begin .ULE unorder list end .OLS ordered list begin .OLE ordered list end .DLS definition list begin .DLE definition list end .LI insert a list item .DC generate a drop capital .HTML pass an html raw request to the device driver .CDS code example begin Groff Version 1.19.2Last change: 21 October 2010 1Device and Network Interfaces GROFF_WWW(7)
.CDE code example end Output of the pic, eqn, refer, and tbl preprocessors is acceptable as input. REQUESTS.JOBNAME filename
Split output into multiple HTML files. A file is split whenever a .SH or .NH 1 is encountered. Its argument is the file stem name for future output files. Thisoption is equivalent to grohtml's -j option.
.HX n Specify the cut off depth when generating links from section headings. For example, a parameter of~2 would cause grohtml to generate a list of links for .NH 1 and .NH 2 but not for .NH 3. Whereas .HX 0 will tell grohtml that no heading links should be created at all. Another method for turning automatic headings off is by issuing the the command line switch-P-l to groff.
.BCL foreground background active not-visited visited
This macro takes five parameters: foreground, back-
ground, active hypertext link, hypertext link not yet visited, and visited hypertext link colour. .BGIMG imagefile the only parameter to this macro is the background image file. .URL url [description] [after]generates a URL using either one, two or three argu-
ments. The first parameter is the actual URL, the second is the name of the link, and the third is optional stuff to be printed immediately afterwards. If description and after are absent then the url becomes the anchor text. Hyphenation is disabled while printing the actual URL; explicit breakpoints should be inserted with the [rs]: escape. Here is how to encode .URL http://[rs]:foo.[rs]:org/ foo :If this is processed by a device other than -Thtml it
appears as: m[blue]foom[] [la]C]http://foo.org][ra]: Groff Version 1.19.2Last change: 21 October 2010 2Device and Network Interfaces GROFF_WWW(7)
The URL macro can be of any type; for example we can reference by: .URL pic.html [dq]Eric Raymond's pic guide[dq] .MTO address [description] [after] Generate an email html reference. The first argument is mandatory as the email address. The optional second argument is the text you see in your browser If an empty argument is given, address is used instead. An optional third argument is stuff printed immediately afterwards. Hyphenation is disabled while printing the actual email address. For example, was achieved by the following macro: .MTO joe@user.org [dq]Joe User[dq]Note that all the URLs actually are treated as consum-
ing no textual space in groff. This could be con-
sidered as a bug since it causes some problems. Tocircumvent this, www.tmac inserts a zero-width charac-
ter which expands to a harmless space (only if run with-Thtml).
.FTP url [description] [after] indicates that data can be obtained via ftp. The first argument is the url and the second is the browser text. A third argument, similar to the macros above, is intended for stuff printed immediately afterwards. Thesecond and the third parameter are optional. Hyphena-
tion is disabled while printing the actual URL. As an example, here the location of the The macro example above was specified by: .FTP ftp://[rs]:ftp.gnu.org/ [dq]GNU ftp server[dq] . .TAG name Generates an html name tag from its argument. This can then be referenced using the macro. As you can see,you must precede the tag name with # since it is a
local reference. This link was achieved via placing a TAG in the URL description above; the source looks like this: .TP .B URL generates .TAG URL a URL using either two or three arguments. ... Groff Version 1.19.2Last change: 21 October 2010 3Device and Network Interfaces GROFF_WWW(7)
.IMG [-R|-L|-C] filename [width] [height]
Include a picture into the document. The first argu-
ment is the horizontal location: right, left, or center(-R, -L, or -C). Alignment is centered by default (-
C). The second argument is the filename. The optional third and fourth arguments are the width and height. If the width is absent it defaults to 1~inch. If the height is absent it defaults to the width. This maps onto an html img tag. If you are including a png image then it is advisable to use the PIMG macro..PIMG [-R|-L|-C] filename [width [height]]
Include an image in PNG format. This macro takes exactly the same parameters as the IMG macro; it hasthe advantage of working with postscript and html dev-
ices also since it can automatically convert the image into the EPS format, using the following programs of the netpbm package: pngtopnm, pnmcrop, and pnmtops.If the document isn't processed with -Thtml it is
necessary to use the -U option of groff.
.MPIMG [-R|-L] [-G gap] filename [width
Place a PNG image on the margin and wrap text around it. The first parameters are optional. The alignment:left or right (-L or -R) specifies the margin where the
picture is placed at. The default alignment is left(-L). Optionally, -G~gap can be used to arrange a gap
between the picture and the text that wraps around it. The default gap width is zero.The first non-optional argument is the filename. The
optional following arguments are the width and height. If the width is absent it defaults to 1~inch. If the height is absent it defaults to the width. Example:.MPIMG -L -G 2c foo.png 3c 1.5c
The height and width may also be given as percentages. The PostScript device calculates the width from the .lregister and the height from the .p register. For exam-
ple:.MPIMG -L -G 2c foo.png 15%
.HnS nBegin heading. The numeric heading level n is speci-
fied by the first parameter. Use this macro if your headings contain URL, FTP or MTO macros. Example: .HnS 1 Groff Version 1.19.2Last change: 21 October 2010 4Device and Network Interfaces GROFF_WWW(7)
.HR GNU Troff .URL http://groff.ffii.org (Groff)- a
.URL http://www.gnu.org/ GNU project. Hosted by .URL http://ffii.org/ FFII . .HR .HnE In this case you might wish to disable automatic linksto headings. This can be done via -P-l from the com-
mand line. .HnE End heading. .LK Force grohtml to place the automatically generated links at this position. If this manual page has beenprocessed with -Thtml those links can be seen right
here..HR Generate a full-width horizontal rule for -Thtml. No
effect for all other devices. .NHR Suppress generation of the top and bottom rules which grohtml emits by default. .HTL Generate an HTML title only. This differs from the TL macro of the ms macro package which generates both an HTML title and anheading. Use it to provide an HTML title as search engine fodder but a graphic title in the document. The macro terminates when a space or break is seen (.sp, .br). .HEAD Add arbitrary HTML data to the block. Ignored
if not processed with -Thtml. Example:
.HEAD [dq][dq] .HTML All text after this macro is treated as raw html. Ifthe document is processed without -Thtml then the macro
is ignored. Internally, this macro is used as a build-
ing block for other higher-level macros.

For example, the BGIMG macro is defined as .de BGIMG. HTML
.. .DC l text [color] Produce a drop capital. The first parameter is the letter to be dropped and enlarged, the second parameter text is the ajoining text whose height the first letter should not exceed. The optional third parameter is the color of the dropped letter. It defaults to black. .CDS Start displaying a code section in constant width font. .CDE End code display SECTION HEADING LINKS By default grohtml generates links to all section headings and places these at the top of the html document. (See for details of how to switch this off or alter the position). LIMITATIONS OF GROHTML tbl information is currently rendered as a PNG image. FILES /usr/share/groff/1.19.2/tmac/www.tmacATTRIBUTES
