Here are some examples of macro definitions:
<$macroMacroName [ modifiers ] [ attributes ]
Hugo-Addressthat only is a shortcut for your email-address like
<$macro Hugo-Address> email@example.com </$macro>So every time, you insert the macro-tag
<Hugo-Address>in your hsc-source, it will be replaced by
firstname.lastname@example.org the HTML-object.
Container macros allow you to create a macros with a text before and after the content. While the preceding/succeeding text is specified with the macro declaration, the content is assigned during the macro call.
To declare a macro as container, you have to specify the modifier
/CLOSE''. To insert the contents, use the special tag
<$content>. Alternatively, you can access the content with
the special attribute
You can use
<$content> multiple times inside the same macro,
To call a container macro, act the same as with the simple macro you have seen in the above example. But different to before, now also a end-tag has to show up. Everything between the corresponding start- and end-tag will be interpreted as content.
You should be aware of the fact that hsc, when scanning for the
end-tag for the macro, does not in process other macros or
<$include>-tags, but only looks at the text. Therefore, the
end-tag has to show up within the same input file as the
Ok, that was a bit much. Probably a good time for an example...
One of the most laughable stories about HTML is the one about
physical and logical styles: It is possible to render text in bold or
italic letters using tags like
<I>, which are
known as physical styles. Furthermore, you can also use some logical
<KBD>, which should be used to
mark sequences of code or user input. Both are usually rendered same
as the physical style
<TT> (typewriter font).
As everyone with a brain implemented could have told from the
beginning, the number of physical styles increased with every new HTML
release. In the draft to (never released) HTML-3.0 tags appeared to
render names of authors, acronyms, persons etc. The lack behind these
concepts became that obvious that even w3c found out it sucks. And so,
probably only soon before tags like
<Tim-Berners-Lee-s-favourite-tag-to-render-his-name> made it
into the specifications, this concepts has been abandoned.
However, it has not been replaced by anything more useful, and this has not changed much until today; except that many people are waiting for a new holy cow called Style Sheets to be implemented in a functioning way in at least some of the available browsers.
So it makes sense to use container macros as substitute for logical
styles, which will do nothing but enclose the content in a physical
style. Below a macro
<FILE> will be created, which can be used
to render filenames:
<$macro FILE /Close><I><$content></I></$macro>Your new style can be used like all other styles:
..open the file <file>hugo.txt</file> and..In this case, filenames will be rendered italic:
..open the file hugo.txt and..
It should be rather obvious how this one works: When calling the
</FILE>, hsc will scan the
input until it reaches a
</FILE>. Anything between the
corresponding start and end tag will be used as content, in this case
Now the macro text will be interpreted: The first part is easy, a
<I> will be inserted. After that, a
shows up, and the content read before will be inserted. In this case,
this is a simple plain text, but of course you could also use tags or
even other (container) macros. At the end of the macro, a closing
</I> is appended, and the macro call exits.
You should be aware that the macro content (the text specified
between the corresponding start and end macro tag) can not access
attributes which have been declared for the macro text (the text which
is assigned to the macro while declaring it using
<$macro sepp /close hugo:string> sepp : hugo=<(hugo)> <$content> sepp : hugo=<(hugo)> </$macro> <$define hugo:string="content's hugo"> <sepp hugo="sepp's hugo"> content: hugo=<(hugo)> </sepp>will result in
sepp : hugo=sepp's hugo content: hugo=content's hugo sepp : hugo=content's hugoThe line
does not - as some might have expected - access the attribute
hugo passed to the container macro
before, but still reads the attribute
hugo declared above
<$content>shows up while just processing a
<$content>, it does not make much sense to include the same content as just before. Instead, the parser uses the content passed to the previous but one container macro. For example:
<$macro hinz /close> hinz=( <$content> ) </$macro> <$macro kunz /close> kunz=( <$content> ) </$macro> <hinz><kunz>...some text...</kunz></hinz>will result in
hinz=( kunz=( ...some text... ) )
<$macro Button.Next NxtRef:uri> <A HREF=(NxtRef)><IMG SRC=":image/next.png" ALT="Next"></A> </$macro>This defines a macro that defines a button that references to the next page. As every page has its own next page, you can set one attribute for this macro:
NXTREF, which is the URI that should be referenced as the ``next'' page.
So an example usage of this macro would be:
<button.next NXTREF=":features/rplcent.html">which will give the button seen below:
Note that the value of
NXTREF is passed to the
HREF attribute within the
<A> tag when the macro
If you wonder, what
HREF=(NxtRef) (see above) should
mean: This sets
HREF with the value stored in
NxtRef. For details, read the section about expressions.
<$macro outer-sepp> now in outer sepp <* define inner-sepp *> <$macro inner-sepp> now in inner sepp </$macro> <* use inner-sepp *> <inner-sepp> </$macro> <outer-sepp>will result in
now in outer sepp now in inner sepp
At the moment you can call
<inner-sepp> even outside of
<outer-sepp>, as it is defined globally. When calling
<outer-sepp> another time, you will receive a message #59,
as this tries to redefine
