string (Function)

Next: string-upcase; string-downcase; string-capitalize; nstring-upcase; nstr+, Previous: char; schar, Up: Strings

Syntax:

— Function: string x → string

Arguments and Values:

x—a string, a symbol, or a character.

string—a string.

Description:

Returns a string described by x; specifically:

If x is a string, it is returned.
If x is a symbol, its name is returned.
If x is a character, then a string containing that one character is returned.
string might perform additional, implementation-defined conversions.

Examples:

 (string "already a string") → "already a string"
 (string 'elm) → "ELM"
 (string #\c) → "c"

Exceptional Situations:

In the case where a conversion is defined neither by this specification nor by the implementation, an error of type type-error is signaled.

Notes:

coerce can be used to convert a sequence of characters to a string.

prin1-to-string, princ-to-string, write-to-string, or format (with a first argument of nil) can be used to get a string representation of a number or any other object.
