<tr><td><code>popup-border</code></td><td>Draw border around <code>popup</code>, <code>menu</code>, <code>all</code>, or <code>none</code></td><td><code>none</code></td></tr>
<tr><td><code>indent-heuristic</code></td><td>How the indentation for a newly inserted line is computed: <code>simple</code> just copies the indentation level from the previous line, <code>tree-sitter</code> computes the indentation based on the syntax tree and <code>hybrid</code> combines both approaches. If the chosen heuristic is not available, a different one will be used as a fallback (the fallback order being <code>hybrid</code> -><code>tree-sitter</code> -><code>simple</code>).</td><td><code>hybrid</code></td></tr>

<p>You may also have to activate them in the LSP config for them to appear, not just in Helix. Inlay hints in Helix are still being improved on and may be a little bit laggy/janky under some circumstances. Please report any bugs you see so we can fix them!</p>
<tr><td><code>git-global</code></td><td>Enables reading global <code>.gitignore</code>, whose path is specified in git's config: <code>core.excludesfile</code> option</td><td><code>true</code></td></tr>
<p>Ignore files can be placed locally as <code>.ignore</code> or put in your home directory as <code>~/.ignore</code>. They support the usual ignore and negative ignore (unignore) rules used in <code>.gitignore</code> files.</p>
<p>Additionally, you can use Helix-specific ignore files by creating a local <code>.helix/ignore</code> file in the current workspace or a global <code>ignore</code> file located in your Helix config directory:</p>
<ul>
<li>Linux and Mac: <code>~/.config/helix/ignore</code></li>
<tr><td><code>render</code></td><td>Whether to render whitespace. May either be <code>"all"</code> or <code>"none"</code>, or a table with sub-keys <code>space</code>, <code>nbsp</code>, <code>nnbsp</code>, <code>tab</code>, and <code>newline</code></td><td><code>"none"</code></td></tr>
<tr><td><code>characters</code></td><td>Literal characters to use when rendering whitespace. Sub-keys may be any of <code>tab</code>, <code>space</code>, <code>nbsp</code>, <code>nnbsp</code>, <code>newline</code> or <code>tabpad</code></td><td>See example below</td></tr>
<tr><td><code>layout</code></td><td>A vector of gutters to display</td><td><code>["diagnostics", "spacer", "line-numbers", "spacer", "diff"]</code></td></tr>
<p>The <code>diff</code> gutter option displays colored bars indicating whether a <code>git</code> diff represents that a line was added, removed or changed.
These colors are controlled by the theme attributes <code>diff.plus</code>, <code>diff.minus</code> and <code>diff.delta</code>.</p>
<p>Other diff providers will eventually be supported by a future plugin system.</p>
<p>There are currently no options for this section.</p>
<tr><td><code>enable</code></td><td>Whether soft wrapping is enabled.</td><td><code>false</code></td></tr>
<tr><td><code>max-wrap</code></td><td>Maximum free space left at the end of the line.</td><td><code>20</code></td></tr>
<tr><td><code>max-indent-retain</code></td><td>Maximum indentation to carry over when soft wrapping a line.</td><td><code>40</code></td></tr>
<tr><td><code>wrap-indicator</code></td><td>Text inserted before soft wrapped lines, highlighted with <code>ui.virtual.wrap</code></td><td><code>↪ </code></td></tr>
<tr><td><code>wrap-at-text-width</code></td><td>Soft wrap at <code>text-width</code> instead of using the full viewport size.</td><td><code>false</code></td></tr>
<tr><td><code>enable</code></td><td>If set to true, then when the cursor is in a position with non-whitespace to its left, instead of inserting a tab, it will run <code>move_parent_node_end</code>. If there is only whitespace to the left, then it inserts a tab as normal. With the default bindings, to explicitly insert a tab character, press Shift-tab.</td><td><code>true</code></td></tr>
<tr><td><code>supersede-menu</code></td><td>Normally, when a menu is on screen, such as when auto complete is triggered, the tab key is bound to cycling through the items. This means when menus are on screen, one cannot use the tab key to trigger the <code>smart-tab</code> command. If this option is set to true, the <code>smart-tab</code> command always takes precedence, which means one cannot use the tab key to cycle through menu items. One of the other bindings must be used instead, such as arrow keys or <code>C-n</code>/<code>C-p</code>.</td><td><code>false</code></td></tr>
<p>Due to lack of support for S-tab in some terminals, the default keybindings don't fully embrace smart-tab editing experience. If you enjoy smart-tab navigation and a terminal that supports the <ahref="https://github.com/helix-editor/helix/wiki/Terminal-Support#enhanced-keyboard-protocol">Enhanced Keyboard protocol</a>, consider setting extra keybindings:</p>
