Review became the step everything else waits on, and that's where I thought a small tool could help: make it easier to see which files still need a person to read them.</p> <p>DiffSeek for GitHub is a Chrome extension that adds this to GitHub's own "Files changed" page rather than replacing it.</p> <h2> Hiding generated files </h2> <p>When you open a PR, generated files and files you've already viewed are hidden, and one click in the filter menu shows them again. A file counts as generated when your repo's root <code>.gitattributes</code> marks it with <code>linguist-generated</code>, the attribute GitHub already uses:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>dist/** linguist-generated=true api/client/** linguist-generated=true </code></pre> </div> <p>These files are also marked viewed automatically, so they count toward your progress.</p> <h2> Progress in the file tree </h2> <p>Each file and folder in GitHub's file tree gets a viewed badge: an empty circle while unread, a half-filled one when partly reviewed, a check once done. Clicking a folder's badge marks its unread visible files as viewed, so on a large PR I can tell what's left by looking at the tree.</p> <p>The filter menu can also show a single CODEOWNERS owner, group or file format at a time.</p> <h2> Privacy </h2> <p>DiffSeek works through your existing GitHub session, so private repos work without a token or account. It has no backend and collects no data.</p> <h2> Try it </h2> <p>The source is on GitHub under the MIT license: <a href="https://github.com/n8v-guy/diffseek" rel="noopener noreferrer">https://github.com/n8v-guy/diffseek</a></p> <p>You can install it from the Chrome Web Store: <a href="https://chromewebstore.google.com/detail/lpohfkpkmaakdllgpognpjegifccnfec" rel="noopener noreferrer">https://chromewebstore.google.com/detail/lpohfkpkmaakdllgpognpjegifccnfec</a></p> <p>If you review a lot of PRs, I'd like to hear what still slows you down, in the comments or as an issue.</p> showdev github codereview opensource
