prin1

(prin1 object &optional stream)

Writes object to standard output in its readable form, exactly like print but without the trailing newline. Strings are printed with surrounding quotes and characters in #\ syntax, so the output could be read back by read. Inside a string every embedded " and \ is preceded by a \; a newline is printed literally. Binding *print-case* converts the case of every symbol printed (Reader Case); *print-length* / *print-level* truncate lists and vectors ((1 2 ...), #), *print-gensym* nil drops a gensym's #:, and *print-base* / *print-radix* re-spell integers and ratios (FF, #xFF, 255.). A symbol's package qualifier is printed only when the symbol is not accessible in the current *package* (Packages). With the optional stream argument the output goes to that stream instead of standard output. Returns object.
