I can't clearly see a use case. I went on to the "why" section but I'm having a hard time trying to understand what this is trying to solve. Perhaps a clear and simple example to see why you would use it could be useful. Also I find it extremely verbose to write HTML the way is shown in the examples at the top. Having used Jinja for a very long time, its simplicity and separation from logic makes it almost (for me) the only templating lang that you need to learn in Python. Writing HTML code the way is shown is clearly not for me, but there might be uses cases for it.
That's a fair point, although my feeling after working quite a bit with Jinja recently is the opposite (primarily for lack of static analysis and IDE support).
You're right, for example the documentation should be improved quite a bit. Keep in mind that this project is pretty new, I simply had no time to add more docs or further improve the existing one.
Ps.: with the Snippet utility and markdown support, you can actually write quite a bit of your HTML in a html files rather than Python. You could even use Jinja templates as the backend for some of your components. This part will see more work as I have spare time to work more on the project.
Sometimes I want to do things totally pure html, with more dynamicness and more reusability. Jinja template fall short.
This! I recently wanted to get back to writing a web app entirely rendered on the server side without the need for a JavaScript framework and I was really struck by how embarrassingly clumsy templating engines are compared to JSX.
