title: VSCode clang-format Xaver extension with no parent location for .clang-format
body: <p>I would like to configure the VSCode Xaver extension to use a .clang-format file that is not in the parent folder, E.g. on the command line you could do this
  &quot;-style=file:&lt;format_file_path&gt;&quot; to explicitly specify the configuration file path.</p>
  <p>I have tried these settings below,</p>
  <pre><code>&quot;clang-format.executable&quot;: &quot;/usr/bin/clang-format-15&quot;,
  </code></pre>
  <p>with</p>
  <pre><code>&quot;clang-format.style&quot;: &quot;file:../40_scripts/shared&quot;,
  </code></pre>
  <p>or even</p>
  <pre><code>&quot;clang-format.style&quot;: &quot;file:${workspaceRoot}/40_scripts/shared&quot;,
  </code></pre>
  <p>and even,</p>
  <pre><code>&quot;clang-format.assumeFilename&quot;: &quot;${workspaceRoot}/40_scripts/shared/.clang-format&quot;,
  </code></pre>
  <p>But i can't get it to work, i see this in the extensions output window
  &quot;Error reading ${workspaceRoot}/40_scripts/shared/.clang-format: No such file or directory&quot;.
  Is it possible with this extension to change the path to the .clang-format file? Thanks.</p>
