Like <code><a href="/link/base%3A%3Ainteractive()?package=rlang&version=1.1.0" data-mini-rdoc="rlang::base::interactive()">base::interactive()</a></code>, <code>is_interactive()</code> returns <code>TRUE</code> when
the function runs interactively and <code>FALSE</code> when it runs in batch
mode. It also checks, in this order:<ul>
<li>The <code>rlang_interactive</code> global option. If set to a single <code>TRUE</code>
or <code>FALSE</code>, <code>is_interactive()</code> returns that value immediately. This
escape hatch is useful in unit tests or to manually turn on
interactive features in RMarkdown outputs.</li>
<li>Whether knitr or testthat is in progress, in which case
<code>is_interactive()</code> returns <code>FALSE</code>.</li>
</ul><code>with_interactive()</code> and <code>local_interactive()</code> set the global
option conveniently.

A toolbox for working with base types, core R features
like the condition system, and core 'Tidyverse' features like tidy
evaluation.

is_interactive function

<dl><dt>value</dt>
<dd>A single <code>TRUE</code> or <code>FALSE</code>. This overrides the return
value of <code>is_interactive()</code>.</dd>

<dd>The environment of a running function which defines
the scope of the temporary options. When the function returns,
the options are reset to their original values.</dd>
