<p>cvc5 can be configured at runtime using a wide range of options.
When cvc5 is used as a binary, options can be set on the command line.
Also, options can be set and inspected using the respective commands of the input language and the corresponding API functions:</p>

</ul>
<p>Generally, all options are identified by a name <code class="docutils literal notranslate"><span class="pre"><name></span></code>, and (optionally)
by a short name <code class="docutils literal notranslate"><span class="pre"><short></span></code> (a single letter).
Additionally, they can have one or more aliases, which can be used instead of
<code class="docutils literal notranslate"><span class="pre"><name></span></code>.</p>
<p><strong>Internally</strong>, options are strongly typed and must be either Boolean, (signed
or unsigned) integers, floating-point numbers, strings, or an enumeration type.
Values for options with a numeric type may be restricted to an interval.</p>
<p>Some options have <strong>custom types</strong> (e.g., <a class="reference internal" href="#lbl-option-err"><span class="std std-ref">err</span></a>) which
require special treatment internally.
The usage of such options is documented as part of the documentation for the corresponding options.</p>
<p>On the command line, a <strong>Boolean</strong> option can be set to <code class="docutils literal notranslate"><span class="pre">true</span></code> via
<code class="docutils literal notranslate"><span class="pre">--<name></span></code> or <code class="docutils literal notranslate"><span class="pre">-<short></span></code>.
Most Boolean options can also be set to <code class="docutils literal notranslate"><span class="pre">false</span></code> via <code class="docutils literal notranslate"><span class="pre">--no-<name></span></code>.
In cvc5’s APIs, this is done via <code class="docutils literal notranslate"><span class="pre">setOption("<name>",</span> <span class="pre">"true"</span> <span class="pre">|</span> <span class="pre">"false")</span></code>.</p>
<p>For <strong>all other types</strong>, values are given on the command line using
<code class="docutils literal notranslate"><span class="pre">--<name>=<value></span></code> or <code class="docutils literal notranslate"><span class="pre">--<name></span> <span class="pre"><value></span></code>,
and <code class="docutils literal notranslate"><span class="pre">setOption("<name>",</span> <span class="pre">"<value>")</span></code> in the APIs.
The given value must be convertible to the appropriate type, in particular for
numeric and enumeration types.</p>
<p>Below is an exhaustive list of options supported by cvc5.</p>
