Introduction

Prosper is great for making slides in L

AT

EX. Viewing the slides on an online computer suggests linking the presentation to a web site. More specifically; we want to link to some section in a web-document created with L

AT

EX and TeX4ht. Let’s see wether this is possible!

How to insert hyperlinks

Here is an example: Bram Stoker wrote “Dracula” more than a century

• ago. On Project Gutenberg you can find “Dracula”

and hundreds of public domain books online. The link was inserted with the \href{url}{text}

• command. This command resides in the

hyperref-package, which included by prosper. Thus, to insert a hyperlink to an external web-document, one only has to insert the appropriate \href-command.

How to insert hyperlinks cont.

Note that the urlcolor-parameter to hyperref is

• bscured by the prosper class, so the best way to do

create a colored hyperlink is to precede the text with a color-command, e.g. {\green \underline{text}}

Creating hyperlinks in TeX4ht

With TeX4ht one can create splendid html-versions of L

AT

EX-documents. The only trouble is how to know the name of the links to various html-pages created. Solution: Exploit TeX4ht’s “hooks” when issuing sectioning commands. I have written a collection of macros in customlinks.tex to accomplish this task. Simply issue \include{customlinks.tex} after \begin{document}, and the hooks will be set up.

Creating hyperlinks in TeX4ht cont.

After compiling the document, run cat doc.log | grep Customlinks >links.txt to create a text file containing descriptions of all the

• links. They are all easily read and remembered.

(doc.log is the logfile from your main document.) You can also create custom links wherever you want, with the \customlink and \pagelink commands. Do you want to know more? See the L

AT

EX Web Companion and the customlinks.tex source.

A simple example: dracula.tex

dracula.tex contains some bloody sections. The document is converted to html with TeX4ht. See it here! (For the sake of simplicity, we don’t split the document over several html-files.) After running the cat-command mentioned on the previous slide, we get this text-file describing the links:

• -- Customlinks says: Link to chapter 1: dracula.html#ch1
• -- Customlinks says: Link to section 1.1: dracula.html#sec1-1
• -- Customlinks says: Link to chapter 2: dracula.html#ch2
• -- Customlinks says: Link to section 2.1: dracula.html#sec2-1

Now, let’s see section 2.1, which is from Jonathan Harker’s journal: Jonathan harker’s journal.
