<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Now that <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-7"><a href="https://www.drupal.org/project/drupal/issues/2313917" title="Status: Closed (fixed)">#2313917: Core version key in module's .info.yml doesn't respect core semantic versioning</a></span> is committed</p>
<p>Projects can specify drupal core compatibility through `<code>core_version_requirement</code>` key. This key is already in the composer semver format.</p>
<p>This should be used to determine which version of Drupal core to require if composer.json doesn't require drupal/core.</p>
<p>It seems that </p>
<pre>dependencies:<br> - drupal:system (>= 8.5)</pre><p>
Also affects the <code>drupal/core</code> requirement<br>
From testing <a href="https://git.drupalcode.org/project/token">https://git.drupalcode.org/project/token</a> which has no composer.json.</p>
<p>The <code>core_version_requirement</code> should probably take precedence over this if both are present.</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Use <code>core_version_requirement</code> to determine <code>drupal/core</code> requirement if it is not specified in a composer.json file.</p>
<p>The precedence is as follows:</p>
<ul>
<li>If <code>drupal/core</code> is listed as a dependency in <code>composer.json</code>, that value will be used.</li>
<li>Otherwise, if <code>core_version_requirement</code> is set in the <code>.info.yml</code> file, that value will be used.</li>
<li>Otherwise, if the <code>info.yml</code> file declares a version dependency on any core module, that version will be used.</li>
</ul>
<h3 id="summary-remaining-tasks">Remaining tasks</h3>
<p>Determine if other keys in the info.yml file should affect the Drupal core requirement. </p>
