GROFF_MWWW(W) GROFF_MWWW(W) NAME groff_mwww - groff macros for authoring web pages SYNOPSIS groff -mwww [ options ] file ... DESCRIPTION This manual page describes the GNU -mwww macros, 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 dis- tribution 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. SYNPOSIS .HTMLINDEX determine automatic link cut off point for sections/headers .BODYCOLOR specify colours on a web page .BACKGROUND specify background image .URL create a url using two parameters .MAILTO create a html email address .FTP create an ftp reference .IMAGE include an image file .HTML pass an html raw request to the device driver .TAG generate an html name tag from $1 .LINE create a full width horizontal rule Output of the pic, eqn, refer, and tbl preprocessors is acceptable as input. REQUESTS HTMLINDEX determines the cut off point for automatic link generation to headings. By default all headings found in a troff document have links created to them at the top of the html web page. It maybe that many of the lower heading levels do not require links. Alternatively some web pages may not need any heading links at all, in which case: .HTMLINDEX 0 will tell grohtml not to generate links. An HTM- LINDEX of 2 will mean that a heading 1.1.1 Some Title will not be included in the links either as it is said to have a heading level of three. Another method for switching automatic headings is via the command line switch -P-l. BODYCOLOR takes five parameters: foreground, background, active hypertext link, hypertext link not yet vis- ited, and visited hypertext link colour. BACKGROUND the only parameter to this macro is the background image file. URL generates a URL using either two or three argu- ments. $1 is the name of the link, $2 is the actual URL, and $3 is optional stuff to be printed immediately after $2. Hyphenation is disabled while printing the actual URL; explicit breakpoints should be inserted with the \: escape. Here is how to encode homepage for groff <http://groff.ffii. org/>: .URL "homepage for groff" http://\:groff.\:ffii.\:org/ : If this is processed by a device other than -Thtml it appears as: homepage for groff <http://groff. ffii.org>. The URL macro can be of any type; for example we can reference Eric Raymond's pic guide <pic.html> by: .URL "Eric Raymond's pic guide" pic.html MAILTO generates an email html reference. The first argu- ment is mandatory as the email address. The optional second argument is the text you see in your browser, and an optional third argument is stuff printed immediately after the second argu- ment. Hyphenation is disabled while printing the actual email address. For example, the groff main- tainers are Werner Lemberg <wl@gnu.org> and Ted Harding <Ted.Harding@nessie.mcc.ac.uk>. This is achieved by the following macros: .MAILTO wl@gnu.org "Werner Lemberg" .MAILTO Ted.Harding@nessie.mcc.ac.uk "Ted Harding" . Note that all the urls actually are treated as con- suming no textual space in groff. This could be considered as a bug since it causes some problems. To circumvent this, www.tmac inserts a zero-width character which expands to a harmless space (only if run with -Thtml). FTP indicates that data can be obtained via ftp. The first argument is the browser text and the second is the url. A third argument, similar to the macros above, is intended for stuff printed immedi- ately after the second argument. The second and the third parameter are optional. Hyphenation is disabled while printing the actual URL. As an example, here the location of the current groff development distribution <ftp://ftp.ffii.org/pub/ groff/devel/groff-current.tar.gz>. The macro exam- ple above was specified by: .FTP "current groff development distribution" \ ftp://ftp.ffii.org/\:pub/\:groff/\:devel/\:groff-current.tar.gz . IMAGE allows the document to include pictures. The first argument is the image file. The second optional argument gives the horizontal location; l puts the image to the left border, r to the right. Any other value centers the image. The next two argu- ments are optional also: Argument three is the width in pixels (default is 400 pixels if absent). The fourth argument is the height in pixels (default is the width value if absent). HTML all text after this macro is treated as raw html. If the document is processed without -Thtml then the macro is ignored. This macro is a building block for other higher level macros. For example, the BACKGROUND macro is defined as: .de BACKGROUND . HTML <body background=\$1> .. TAG generates an html name tag from its argument. This can then be referenced using the URL <#URL> 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. $1 is the name of the link, $2 is the actual URL. LINE generates a full width horizontal rule. Example: .LINE LINKS requests that grohtml place the automatically gen- erated links at this position. For example: SECTION HEADING LINKS By default grohtml generates links to all section headings and places these at the top of the html document. (See LINKS <#LINK> for details of how to switch this off or alter the position. LIMITATIONS OF GROHTML Tbl information is currently rendered as a png image.
