code_theme_list

<code>code_theme_list()</code> lists the built-in code themes.

A suite of tools to build attractive command line interfaces
('CLIs'), from semantic elements: headings, lists, alerts, paragraphs,
etc. Supports custom themes via a 'CSS'-like language. It also
contains a number of lower level 'CLI' elements: rules, boxes, trees,
and 'Unicode' symbols with 'ASCII' alternatives. It support ANSI
colors and text styles as well.

code_theme_list function

A theme is a list of character vectors, except for <code>bracket</code>, see below.
Each character vector must contain RGB colors (e.g. <code>"#a9a9a9"</code>),
and cli styles, e.g. <code>"bold"</code>. Entries in the list:<ul>
<li><code>reserved</code>: reserved words</li>
<li><code>number</code>: numeric literals</li>
<li><code>null</code>: the <code>NULL</code> constant</li>
<li><code>operator</code>: operators, including assignment</li>
<li><code>call</code>: function calls</li>
<li><code>string</code>: character literals</li>
<li><code>comment</code>: comments</li>
<li><code>bracket</code>: brackets: <code>(){}[]</code> This is a list of character vectors,
to create "rainbow" brackets. It is recycled for deeply nested lists.</li>
</ul>

Code themes

In RStudio, it matches the current theme of the IDE.
You can use three options to customize the code theme:<ul>
<li>If <code>cli.code_theme</code> is set, it is used.</li>
<li>Otherwise if R is running in RStudio and <code>cli.code_theme_rstudio</code> is
set, then it is used.</li>
<li>Otherwise if T is not running in RStudio and <code>cli.code_theme_terminal</code>
is set, then it is used.</li>
</ul>You can set these options to the name of a built-in theme, or to list
that specifies a custom theme. See <code>code_theme_list()</code> for the list
of the built-in themes.
