Greetings!
HTML4.LISP (attached) will generate HTML code based on the current DTD (2.0,
3.2, 4.0 strict/transitional/frameset) loaded into the HTML-PARSER. The
HTML-PARSER must be loaded *and* initialized before loading HTML4.
DECLARE functions are generated for ELEMENTS without content (META, LINK,
IMG,...) and WITH macros are generated for ELEMENTS with content (HTML,
HEAD, BODY,...). All but a few (DECLARE-DOCUMENT-TYPE, WITH-HEADING,
WITH-SECTION-HEADING, WITH-PHRASE, WITH-FONTSTYLE) functions/macros are
automatically generated.
The DTD ELEMENT names were chosen as the names of the FUNCTIONS/MACROS (with
the appropriate DECLARE- or WITH- suffix) and the DTD ATTRIBUTE names were
chosen as the names of the attribute parameters. For example, WITH-HEAD,
DECLARE-META, :LANG, and :DIR. Alias function/macros are created in an
attempt to be somewhat backwardly compatible: for example, WITH-PARAGRAPH
may be used instead of WITH-P. You may generate your own aliased
functions/macros for any of the elements defined in the DTD. (See the code.)
However, aliases are not created for attributes: so, for example, :ALIGN
must be used instead of :ALIGNMENT. Furthermore, keyword parameters are used
almost exclusively for attributes: the exception being backwardly compatible
functions/macros like DECLARE-TITLE and WITH-SECTION-HEADING. Use the
CL-HTTP Documentation Facility after loading this file for a complete list
of HTML4 functions, macros, and attributes for the currently-loaded DTD.
Missing required attributes (for example, BDO DIR) signal an error.
Extraneous attributes are simply ignored (or should they also signal an
error?) Attribute values are verified and bad values signal an error.
However, this verification is somewhat loose: for example, pixels are
verified as cdata (as currently defined in the HTML-PARSER DTDs).
Tested under MacIvory/Genera 8.3, CL-HTTP 156, HTML-PARSER V11. Comments and
ports to other LISPs welcome!
