Though not strictly necessary, the library attempts to generate
reasonable layout in SGML output. It does this only by inserting
newlines before and after tags. It does this on the basis of the
multifile predicate html_write:layout/3
- html_write:layout(+Tag,
-Open, -Close)
- Specify the layout conventions for the element Tag, which is
a lowercase atom. Open is a term Pre-Post.
It defines that the element should have at least Pre newline
characters before and Post after the tag. The Close
specification is similar, but in addition allows for the atom
-empty,
telling the library that the element has declared empty content. In this
case the close-tag is not emitted either, but in addition html//1
interprets Arg in Tag(Arg) as a list of
attributes rather than the content.
A tag that does not appear in this table is emitted without
additional layout. See also print_html/[1,2].
Please consult the library source for examples.
