Function: eval-print-last-sexp

eval-print-last-sexp is an interactive and byte-compiled function defined in elisp-mode.el.gz.

Signature

(eval-print-last-sexp &optional EVAL-LAST-SEXP-ARG-INTERNAL)

Documentation

Evaluate sexp before point; print value into current buffer.

Normally, this function truncates long output according to the value of the variables eval-expression-print-length and eval-expression-print-level. With a prefix argument of zero, however, there is no such truncation. Such a prefix argument also causes integers to be printed in several additional formats
(octal, hexadecimal, and character).

If eval-expression-debug-on-error is non-nil, which is the default, this command arranges for all errors to enter the debugger.

Probably introduced at or before Emacs version 22.1.
