====== Function STRING ====== ====Syntax==== * **string** //x// → //string// ====Arguments and Values==== * //x// - a //[[CL:Glossary:string]]//, a //[[CL:Glossary:symbol]]//, or a //[[CL:Glossary:character]]//. * //string// - a //[[CL:Glossary:string]]//. ====Description==== Returns a //[[CL:Glossary:string]]// described by //x//; specifically: * If //x// is a //[[CL:Glossary:string]]//, it is returned. * If //x// is a //[[CL:Glossary:symbol]]//, its //[[CL:Glossary:name]]// is returned. * If //x// is a //[[CL:Glossary:character]]//, then a //[[CL:Glossary:string]]// containing that one //[[CL:Glossary:character]]// is returned. * **string** might perform additional, //[[CL:Glossary:implementation-defined]]// conversions. ====Examples==== <blockquote> (string "already a string") <r>"already a string" </r> (string 'elm) <r>"ELM" </r> (string #\\c) <r>"c" </r> </blockquote> ====Affected By==== None. ====Exceptional Situations==== In the case where a conversion is defined neither by this specification nor by the //[[CL:Glossary:implementation]]//, an error of type **[[CL:Types:type-error]]** is signaled. ====See Also==== * **[[CL:Functions:coerce|Function COERCE]]** * **[[CL:Types:string|Type STRING]]** ====Notes==== **[[CL:Functions:coerce]]** can be used to convert a //[[CL:Glossary:sequence]]// of //[[CL:Glossary:characters]]// to a //[[CL:Glossary:string]]//. **[[CL:Functions:prin1-to-string]]**, **[[CL:Functions:princ-to-string]]**, **[[CL:Functions:write-to-string]]**, or **[[CL:Functions:format]]** (with a first argument of **[[CL:Constant Variables:nil]]**) can be used to get a //[[CL:Glossary:string]]// representation of a //[[CL:Glossary:number]]// or any other //[[CL:Glossary:object]]//. \issue{CHARACTER-PROPOSAL:2-1-1} \issue{CHARACTER-PROPOSAL:2-1-1} \issue{STRING-COERCION:MAKE-CONSISTENT} \issue{STRING-COERCION:MAKE-CONSISTENT}
