nospaces.py

import re

from django.utils.encoding import force_text
from django.template import Library, Node


register = Library()

    value = force_text(value)
    value = re.sub(r'\s+', ' ', value)

        self.nodelist = nodelist

    def render(self, context):
        return strip_spaces_in_tags(self.nodelist.render(context).strip())


@register.tag

Use from django.utils.encoding import force_str for newer Django versions.

@kontur I would usually just react to a helpful comment, but since I can't in gist: thanks so much!
To add more context: I used Django 5.2.4.
