Function TERPRI, FRESH-LINE

Syntax:

terpri `&optional` output-stream => nil

fresh-line `&optional` output-stream => generalized-boolean

Arguments and Values:

output-stream -- an output stream designator. The default is standard output.

generalized-boolean---a generalized boolean.

Description:

terpri outputs a newline to output-stream.

fresh-line is similar to terpri but outputs a newline only if the output-stream is not already at the start of a line. If for some reason this cannot be determined, then a newline is output anyway. fresh-line returns true if it outputs a newline; otherwise it returns false.

Examples:

     (with-output-to-string (s)
        (write-string "some text" s)
        (terpri s)
        (terpri s)
        (write-string "more text" s))
    =>  "some text

    more text"
     (with-output-to-string (s)
        (write-string "some text" s)
        (fresh-line s)
        (fresh-line s)
        (write-string "more text" s))
    =>  "some text
    more text"

Side Effects:

The output-stream is modified.

Affected By:

*standard-output*, *terminal-io*.

Exceptional Situations:

None.

See Also: None.

Notes:

terpri is identical in effect to

     (write-char #\Newline output-stream)
