.SH 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
|
|
.RB ( 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
|
|
\fCtroffrc\fP file) if you use \fC-Thtml\fP.
|
|
.PP
|
|
To see the hyperlinks in action, please format this man page with the
|
|
.B grohtml
|
|
device.
|
|
.PP
|
|
Here is a summary of the functions found in this macro set.

|
|
.SH REQUESTS
|
|
.TP
|
|
.B 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:
|
|
.sp
|
|
.nf
|
|
\fC\&.HTMLINDEX 0\fP
|
|
.fi
|
|
.sp
|
|
will tell
|
|
.B grohtml
|
|
not to generate links.
|
|
An \fCHTMLINDEX\fP of 2 will mean that a heading
|
|
.sp
|
|
.B "1.1.1 Some Title"
|
|
.sp
|
|
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 \fC-P-l\fP.
|
|
.TP
|
|
.B BODYCOLOR
|
|
takes five parameters: foreground, background, active hypertext link,
|
|
hypertext link not yet visited, and visited hypertext link colour.
|
|
.TP
|
|
.B BACKGROUND
|
|
the only parameter to this macro is the background image file.
|
|
.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, 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
|
|
.B \e:
|
|
escape.
|
|
Here is how to encode
|
|
.URL "homepage for groff" http://\:groff.\:ffii.\:org/ :
|
|
.sp
|
|
.nf
|
|
\s-2\fC\&.URL "homepage for groff" http://\e:groff.\e:ffii.\e:org/ :\fP\s+2
|
|
.fi
|
|
.sp
|
|
If this is processed by a device other than \fC-Thtml\fP
|
|
it appears as:
|
|
homepage for groff \(lahttp://groff.\:ffii.\:org\(ra.
|
|
The URL macro can be of any type; for example we can reference
|
|
.URL "Eric Raymond's pic guide" pic.html
|
|
by:
|
|
.sp
|
|
.nf
|
|
\s-2\fC\&.URL "Eric Raymond's pic guide" pic.html\fP\s+2
|
|
.fi
|
|
.sp
|
|
.TP
|
|
.B MAILTO
|
|
generates 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, and
|
|
an optional third argument is stuff printed immediately after the
|
|
second argument.
|
|
Hyphenation is disabled while printing the actual email address.
|
|
For example, the groff maintainers are
|
|
.MAILTO wl@gnu.org "Werner Lemberg"
|
|
and
|
|
.MAILTO Ted.Harding@nessie.mcc.ac.uk "Ted Harding" .
|
|
This is achieved by the following macros:
|
|
.sp
|
|
.nf
|
|
\s-2\fC\&.MAILTO wl@gnu.org "Werner Lemberg"
|
|
\&.MAILTO Ted.Harding@nessie.mcc.ac.uk "Ted Harding" .\s+2\fP
|
|
.fi
|
|
.sp
|
|
Note that all the urls actually are treated as consuming no textual space
|
|
in groff.
|
|
This could be considered as a bug since it causes some problems.
|
|
To circumvent this, \fCwww.tmac\fP inserts a zero-width character which
|
|
expands to a harmless space (only if run with -Thtml).
|
|
.TP
|
|
.B 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
|
|
immediately 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
|
|
.FTP "current groff development distribution" \
|
|
ftp://ftp.ffii.org/\:pub/\:groff/\:devel/\:groff-current.tar.gz .
|
|
The macro example above was specified by:
|
|
.sp
|
|
.nf
|
|
\s-2\fC\&.FTP "current groff development distribution" \\
|
|
ftp://ftp.ffii.org/\e:pub/\e:groff/\e:devel/\e:groff-current.tar.gz .\fP\s+2
|
|
.fi
|
|
.sp
|
|
.TP
|
|
.B IMAGE
|
|
allows the document to include pictures.
|
|
The first argument is the image file.
|
|
The second optional argument gives the horizontal location;
|
|
.B l
|
|
puts the image to the left border,
|
|
.B r
|
|
to the right.
|
|
Any other value centers the image.
|
|
The next two arguments 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).
|
|
.sp
|
|
.TP
|
|
.B HTML
|
|
all text after this macro is treated as raw html.
|
|
If the document is processed \fIwithout\fP \fC-Thtml\fP then
|
|
the macro is ignored.
|
|
This macro is a building block for other higher level macros.
|
|
.sp
|
|
For example, the \fCBACKGROUND\fP macro is defined as:
|
|
.nf
|
|
\fC\&.de BACKGROUND
|
|
\&. HTML <body background=\\$1>
|
|
\&..
|
|
\fP
|
|
.fi
|
|
.TP
|
|
.B TAG
|
|
generates an html name tag from its argument.
|
|
This can then be referenced using the
|
|
.URL URL #URL
|
|
macro.
|
|
As you can see, you must precede the tag name with `\fC#\fP' since it is
|
|
a local reference.
|
|
This link was achieved via placing a TAG in the URL description above;
|
|
the source looks like this:
|
|
.sp
|
|
.nf
|
|
\s-2\fC\&.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.\fP\s+2
|
|
.fi
|
|
.sp
|
|
.TP
|
|
.B LINE
|
|
generates a full width horizontal rule.
|
|
Example:
|
|
.sp
|
|
.nf
|
|
\fC\s-2\&.LINE\fP\s+2
|
|
.fi
|
|
.sp
|
|
.TP
|
|
.B LINKS
|
|
.TAG LINK
|
|
requests that grohtml place the automatically generated links at this position.
|
|
For example:
|
|
.LINKS
|
|
.SH
|
|
SECTION HEADING LINKS
|
|
.LP
|
|
By default
|
|
.B grohtml
|
|
generates links to all section headings and places these at the top of the
|
|
html document. (See
|
|
.URL LINKS #LINK
|
|
for details of how to switch this off or alter the position.
