Most of the names of the structures listed here have been fashioned
after their LaTeX[6] equivalent. New structures can be defined
by means of the html_expansion/2 predicate. Note that these structures take priority over the above
ones.
- start
- Used at the beginning of a document (translates to
<html>).
- end
- Used at the end of a document (translates to
</html>).
- --
- Produces a horizontal rule (translates to
<hr>).
\\
- Produces a line break (translates to
<br>).
- $
- Produces a paragraph break (translates to
<p>).
- comment(Comment)
- Used to insert an HTML comment
(translates to<!- Comment ->).
- title(Title)
- Used to give a title to a document
(translates to a
<title> environment).
- image(Addr)
- Used to include an image of address (URL)
Addr (translates to an
<img> element).
- image(URL,Atts)
- Idem with the list of attributes
Atts.
- ref(Addr,Text)
- Produces a hypertext link, Addr
is the URL of the referenced resource, Text is the text of the
reference (translates to
<a href="Addr">Text</a>).
- label(Label,Text)
- Labels Text as a target
destination with label Label (translates to
<a name="Label">Text</a>).
- heading(N,Text)
- Produces a heading of level N
(1 <= N <= 6), Text is the
text to be used as heading
(translates to a
<hN> environment).
- itemize(Items)
- Produces a list of bulleted items,
Items is a list of corresponding HTML terms (translates to a
<ul> environment).
- nice_itemize(Items)
- Same as above, but uses nicer
bullets. The bullet used can be changed through the predicate
icon_address/2. (See the source
file for details.)
- enumerate(Items)
- Produces a list of numbered items,
Items is a list of corresponding HTML terms (translates to an
<ol> environment).
- description(Defs)
- Produces a list of defined items,
Defs is a list whose elements are definitions, each of them
being a Prolog sequence (composed by ','/2 operators). The last
element of the sequence is the definition, the other (if any) are the
defined terms (translates to an
<dl> environment). The example files should clarify this point.
- preformatted(Text)
- Used to include preformatted text,
Text is a list of HTML terms, each element of the list being a
line of the resulting document (translates to a
<pre>
environment).
- verbatim(Text)
- Used to include text verbatim, special
HTML characters (<,>,&,") are translated into its quoted HTML
equivalent.
- nl
- Used to include a newline in the HTML source (just to
improve human readability).
- begin(Tag,Atts)
- It translates to the start of an
HTML environment of name Tag and attributes Atts. There
exists also a begin(Tag) structure. Useful, in conjunction
with the next structure, when including in a document output generated
by an existing piece of code (e.g. Tag = pre). Its use is
otherwise discouraged.
- end(Tag)
- Translates to the end of an HTML environment of
name Tag.
