| HX | 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 |
| | 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 | This macro takes five parameters: foreground, background, active hypertext link, hypertext link not yet visited, and visited hypertext link colour. |
| BGIMG | the only parameter to this macro is the background image file. |
| URL | generates a URL using either two or three arguments. 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. 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: |
| | 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 | 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, and 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: |
| | 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, 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 url and the second is the browser text. A third argument, similar to the macros above, is intended for stuff printed immediately afterwards. The second and the third parameter are optional. Hyphenation 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 | 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.
...

|
| IMG | Include a picture into the document. The first argument is the horizontal location: right, left, or center (-R, -L, or -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 | Include an image in PNG format. This macro takes exactly the same parameters as the IMG macro; it has the advantage of working with postscript and html devices 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 | Place a PNG image on the margin and wrap text around it. The first parameter is the alignment: left or right (-L or -R). 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. |
| HnS | Begin heading. The heading level is specified by the first parameter. Use this macro of your headings contain URLs. Example: |
| HnE | End heading. |
| LK | Force grohtml to place the automatically generated links at this position. If this manual page has been processed with -Thtml those links can be seen right here. |
|
--> |
|
| HR | Generate a full-width horizontal rule. |
| 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 an H1 heading. Use it to provide an HTML title as search engine fodder but a graphic title in the document. |
| HTML | All text after this macro is treated as raw html. If the document is processed without -Thtml then the macro is ignored. Internally, this macro is used as a building block for other higher-level macros. |
| | For example, the BGIMG macro is defined as --> |
|
| |
.de BGIMG
. HTML <body background=[rs]$1>
..
| |
|
| DC | Produce a drop capital. The first parameter is the letter to be dropped and enlarged, the second parameter is the ajoining text whose height the first letter should not exceed. The optional third parameter is the color of the dropped letter. |
