      <p>Instead of running the same commands over and over again, some of the command-line tools that I use have a <code>watch</code> mode and will automatically re-run when files are changed, however, not all do.</p>

      <p>Instead of doing this manually, I can achieve the same thing though using a tool called <code>nodemon</code> - a script monitor for node projects, but it can work with non-node projects too.</p>

      <p>Here's an example where I'm automatically re-running my PHPUnit tests using a <code>just test</code> recipe each time a file within my custom modules directory changes:</p>

      <pre><code>nodemon \
        --watch web/modules/custom \
        --ext '*' \
        --exec "just test --stop-on-failure --colors=always"
      </code></pre>

      <p>I specify the files or directories I want to watch, which file extensions should trigger a restart (in this case, I've enabled all extensions), and the command to execute.</p>

      <p>This watches all files and run all of the tests, but I can filter either if I need to.</p>

      <p>As well as PHP tools like PHPUnit and PHPStan, I also use this for other things such as when creating presentation slides with rst2pdf where I can automatically re-generate the PDF whenever I update the rst file.</p>
