Parse an input source with the parse function.

(parse source) → wikitext/c

source : (or/c port? string?)

Parse the source into a wikitext object.

(wikitext? x) → boolean?

x : any/c

Returns #t if x is a parsed wikitext object.

You can retrieve the body of the parsed text as an xexpr. The various creole markup commands are transformed into an HTML-like xexpr, which can then be processed as desired.

(body wikitext) → (listof xml:xexpr?)

wikitext : wikitext/c

Extract the body of the document from the wikitext object.

If there are any keywords in the input text (indicated by ::keyword value), then these can be retrieved by one of a family of lookup functions:

(lookup wikitext key) → (or/c string? false/c)

wikitext : wikitext/c

key : symbol?

Retrieve the metadata value corresponding to key key. If several were specified, they are concatenated.

(lookup/multiple wikitext key) → (listof string?)

wikitext : wikitext/c

key : symbol?

Retrieve the multiple metadata values corresponding to key, or an empty list if there was none.

(lookup-parsed wikitext key) → any

wikitext : wikitext/c

key : symbol?

Like lookup, except that, depending on the key, the value is returned as a parsed object. The only ones treated specially are 'date and 'updated, which are returned as SRFI-19 date objects.

(lookup-keys wikitext) → (listof symbol?)

wikitext : wikitext/c

Return the list of available keys.

(set-metadata! wikitext key value) → any

wikitext : wikitext/c

key : symbol?

value : string?

Set a metadata key to have the given value. This appends the value, so that the value changes for LOOKUP, but is extended for LOOKUP/MULTIPLE.
