Hi Thomas As I understand there wouldn't be much required by Django to support this - just one function. So if it came to Python, I think we'd like to see a working snippet, maybe in a third party package, before merging support.
In terms of the PEP, - there are already "too many" ways to template a string in Python, so I'm not sure it will be very popular. A few alternatives spring to mind, beyond those discussed in your related forum thread ( https://forum.djangoproject.com/t/rethinking-how-to-create-html-f-string-like-with-conditional-escape/8212 ). First, there's syntactic macros in PEP 638 ( https://www.python.org/dev/peps/pep-0638/ ). They would provide some extensibility to Python's grammar, so features like your HTML string would not need to go through PEP's and Python releases. They could just be installable packages. Definitely check that out - it seems like it's still in draft phase though. Second, a related way to emulate such macros currently is with a codec. Check out the future-fstrings package, which backported f-strings to older versions of Python: https://github.com/asottile/future-fstrings . As a "wrapper" text codec, it gets to pre-process the source code before passing it on to Python to execute. You could do your template string transformation with the current version of Python like this. Third, stack inspection would also allow you to emulate template strings. Take this example: import inspect from django.utils.html import format_html def html(string): locals_ = inspect.currentframe().f_back.f_locals return format_html(string, **locals_) def main(): name = "Adam" statement = "I'm < 120 years old" print(html("<strong>{name}</strong> says <em>{statement}</em>")) if __name__ == "__main__": main() Running it: $ python ex.py <strong>Adam</strong> says <em>I'm < 120 years old</em> On Fri, 11 Jun 2021 at 08:52, guettli <guettli.goo...@thomas-guettler.de> wrote: > Hi, > > Since I use the html-fragments-over-the-wire pattern (htmx) I create > small function based views returning small html fragments. > > Up to now I use format_html(). > > I am tired of passing in the variables like `foo=foo, bar=bar` into > format_html(). > > I created a Python PEP to introduce a new way. > > The goal is to have something like the convenient f-string syntax > combined with conditional_escape(). > > The draft is here: > > Template Literals: > https://github.com/guettli/peps/blob/master/pep-9999.rst > > I am looking for feedback.
