Edebug does this for you; it binds <code>print-length</code> and <code>print-level</code> to the values of the variables <code>edebug-print-length</code> and <code>edebug-print-level</code> (so long as they have non-<code>nil</code> values). See <a href="output-variables">Output Variables</a>. </p> <dl> <dt id="edebug-print-length">User Option: <strong>edebug-print-length</strong> -</dt> <dd><p>If non-<code>nil</code>, Edebug binds <code>print-length</code> to this value while printing results.

The ‘<samp>#1=</samp>’ notation labels the structure that follows it with the label ‘<samp>1</samp>’, and the ‘<samp>#1#</samp>’ notation references the previously labeled structure. This notation is used for any shared elements of lists or vectors. </p> <dl> <dt id="edebug-print-circle">User Option: <strong>edebug-print-circle</strong> -</dt> <dd><p>If non-<code>nil</code>, Edebug binds <code>print-circle</code> to this value while printing results.
