How it does this depends on the data type of the object, according to rules described in this chapter. The interpreter runs automatically to evaluate portions of your program, but can also be called explicitly via the Lisp primitive function <code>eval</code>. </p> <table class="menu" border="0" cellspacing="0"> <tr> +<td align="left" valign="top">• <a href="intro-eval" accesskey="1">Intro Eval</a> +</td> +<td> </td> +<td align="left" valign="top">Evaluation in the scheme of things. </td> +</tr> <tr> +<td align="left" valign="top">• <a href="forms" accesskey="2">Forms</a> +</td> +<td> </td> +<td align="left" valign="top">How various sorts of objects are evaluated. </td> +</tr> <tr> +<td align="left" valign="top">• <a href="quoting" accesskey="3">Quoting</a> +</td> +<td> </td> +<td align="left" valign="top">Avoiding evaluation (to put constants in the program). </td> +</tr> <tr> +<td align="left" valign="top">• <a href="backquote" accesskey="4">Backquote</a> +</td> +<td> </td> +<td align="left" valign="top">Easier construction of list structure. </td> +</tr> <tr> +<td align="left" valign="top">• <a href="eval" accesskey="5">Eval</a> +</td> +<td> </td> +<td align="left" valign="top">How to invoke the Lisp interpreter explicitly. </td> +</tr> <tr> +<td align="left" valign="top">• <a href="deferred-eval" accesskey="6">Deferred Eval</a> +</td> +<td> </td> +<td align="left" valign="top">Deferred and lazy evaluation of forms. </td> +</tr> </table><div class="_attribution"> + <p class="_attribution-p"> + Copyright © 1990-1996, 1998-2022 Free Software Foundation, Inc. <br>Licensed under the GNU GPL license.<br> + <a href="https://www.gnu.org/software/emacs/manual/html_node/elisp/Evaluation.html" class="_attribution-link">https://www.gnu.org/software/emacs/manual/html_node/elisp/Evaluation.html</a> + </p> +</div> |
