+ READEXPR &key primary-prompt secondary-prompt history
+
+ primary-prompt -- a string (default "=> ")
+ secondary-prompt -- a string (default "| ")
+ history -- a boolean (default t)
+
+ As READLINE, except reads enough lines to complete a lisp
+ expression.
+
+ Primary-prompt controls the prompt of the first line,
+ secondary prompt the prompt of the rest of the lines.
+
+
+ READLINE &key prompt history
+
+ prompt -- a string (default "")
+ history -- a boolean (default t)
+
+ Prompt is the prompt displayed to user.
+
+ History controls whether the string read is added to history, or
+ not. Note that history is available in any case. Currently there
+ is no way to erase history. Leading and trailing whitespace is trimmed
+ from string before they are added to history, and strings that consist
+ entirely of whitespace are not saved to history.
+
+ Dispite the cleanups performed on history, strings are returned as
+ read.
