Deprecation

As of 2020-05-10, I've decided to no longer spend time updating this plugin.

UPDATE

I see that rdipardo has put up a fork on GitHub. You may want to check that out instead.

Why?

It's been quite a while since I did any significant work on it. Here's a few reasons for that:

No time. There's many reasons for this, not least my children. Life goes on.
It was written in Delphi. At work, we've moved away from Delphi (to C# and other languages). For me, this means it takes more time to get into this plugin's code.
It uses Internet Explorer's engine, which is becoming more and more obsolete, and shouldn't really be used anymore.
I don't use Notepad++ as often. For many scenarios, other software such as Visual Studio Code or Notepad3 have become my go-to editor. Better looking, cross-platform; and Notepad++ has had a few breaking changes that made upgrading a pain. I do still use it occasionally, but not for any serious web development.

What now?

As long as the plugin works, it works. But if something in a future version of Notepad++ changes, it may not work in those versions. I suggest you check out the GitHub fork mentioned above.

For web development, I now use Visual Studio Code, which sports various extensions (such as Live Preview) that provide functionality similar to this plugin, and more! Some of them even support debugging the preview.

Source code

If you've got a copy of Delphi handy, feel free to download the source code and play with it.
