Then this is the easy way to apply it.</p> <ol class="arabic"> <li><p>You download the patch file, and you save it on your file system, e.g. as <code class="docutils literal">~/Downloads/39.diff</code></p></li> <li><p>You use the command line. Supposing you unpacked the archive in <code class="docutils literal"><span class="pre">~/dev/CDNTaxReceipts-3.1</span></code></p> <pre class="literal-block">cd ~/dev/CDNTaxReceipts-3.1 patch -p1 &lt; ~/Downloads/39.diff</pre> </li> </ol> <p>Here you are. You patched the extension.</p> <p>If you use Windows, the hardest part will be finding a patch executable. On almost every other OS, patch will be available by default.</p></div>https://blog.johanv.org/en/posts/how-to-apply-a-patch/Thu, 25 Feb 2016 19:05:07 GMT
