Example: <string>

The following example parses strings indicated by double-quotes. Usage of the double-quote in the string itself is possible by escaping it

entry {
    default [object:
        '"'
        
        # Match all characters except the quotation character.
        # Match escaped quotation-characters first.
        def string = [['\\"' | (. except \")]+]
        '"'
    ]
}

Valid inputs:

Input	Output
parse('"Hello World"')	{string: 'Hello World'}
parse('"Say hello with \"Hello World\" !"')	{string: 'Say hello with \'Hello World\' !'}

Invalid inputs:

Input	Output
parse('"Ooops')	null (Missing closing quotation-sign)
parse('"Hello " World"')	null (Quotation not escaped)
