HTML Output

Synopsis

(import (data html))

Encoding of S-expressions as HTML5.

S-Expression HTML Grammar

Elements are represented as lists starting with a tag symbol, optionally followed by an association list of attributes and by element contents:

html    → (SYMBOL content ...)
        | (SYMBOL ((SYMBOL . value) ...) content ...)

The value of an attribute may be a boolean or a list of text contents:

value   → BOOLEAN
        | (text ...)

An attribute with value #f is not serialized as HTML5; an attribute with value #t is serialized without a value assignment in HTML5.

The contents of elements and attributes may consist of plain text and entity references represented as symbols or positive integers. Normal elements may also contain other elements:

content → text
        | html

text    → STRING
        | NUMBER
        | SYMBOL

Operations

procedure: (html-tag-rule tag)

procedure: (html-tag-rule tag rule)

procedure: (write-html html)

procedure: (write-html html port)

Write an S-expression as HTML5 to the given port or to the (current-output-port).
