Get current URL in Twig template?

I looked around for the code to get the current path in a Twig template (and not the full URL), i.e. I don't want http://www.sitename.com/page, I only need /page.

{{ path(app.request.attributes.get('_route'),
     app.request.attributes.get('_route_params')) }}

If you want to read it into a view variable:

{% set currentPath = path(app.request.attributes.get('_route'),
                       app.request.attributes.get('_route_params')) %}

The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user, that reference the services you might use in a controller.

Get current url: {{ app.request.uri }} in Symfony 2.3, 3, 4, 5

Get path only: {{ app.request.pathinfo }} (without parameters)

Get request uri: {{ app.request.requesturi }} (with parameters)
