lispdoc - results for format |
(format destination control-string &rest format-arguments) | Function: Provides various facilities for formatting output. CONTROL-STRING contains a string to be output, possibly with embedded directives, which are flagged with the escape character "~". Directives generally expand into additional text to be output, usually consuming one or more of the FORMAT-ARGUMENTS in the process. A few useful directives are: ~A or ~nA Prints one argument as if by PRINC ~S or ~nS Prints one argument as if by PRIN1 ~D or ~nD Prints one argument as a decimal integer ~% Does a TERPRI ~& Does a FRESH-LINE where n is the width of the field in which the object is printed. DESTINATION controls where the result will go. If DESTINATION is T, then the output is sent to the standard output stream. If it is NIL, then the output is returned in a string as the value of the call. Otherwise, DESTINATION must be a stream to which the output will be sent. Example: (FORMAT NIL "The answer is ~D." 10) => "The answer is 10." FORMAT has many additional capabilities not described here. Consult the manual for details.

babel:external-format | Type: An EXTERNAL-FORMAT consists in a combination of a Babel CHARACTER-ENCODING and an end-of-line style.

(alexandria.0.dev:format-symbol package control &rest arguments) | Function: Constructs a string by applying ARGUMENTS to string designator CONTROL as if by FORMAT, and then creates a symbol named by that string. If PACKAGE is NIL, returns an uninterned symbol, if package is T, returns a symbol interned in the current package, and otherwise returns a symbol interned in the package designated by PACKAGE.
