<p>Language-specific settings and settings for particular language servers can be configured in a <code>languages.toml</code> file placed in your <ahref="./configuration.html">configuration directory</a>. Helix actually uses two <code>languages.toml</code> files, the <ahref="https://github.com/helix-editor/helix/blob/master/languages.toml">first one</a> is in the main helix repository; it contains the default settings for each language and is included in the helix binary at compile time.

If a user wants to disable auto-format, they can change the <code>languages.toml</code> in their <ahref="./configuration.html">configuration directory</a> to make the rust entry read like the example below; the new key/value pair <code>auto-format = false</code> will override the default when the two sets of settings are merged on start-up:</p>
