Cannot change jinja2 variable_start_string and variable_end_string, NonTemplatedInputDirException

[sacha-c]

• Cookiecutter version: 2.4.0
• Template project url: N/A
• Python version: 3.10.9
• Operating System: MacOS

Description:

Overriding jinja's variable_start_string and variable_end_string when using _jinja2_env_vars in cookiecutter.json gives an error NonTemplatedInputDirException.

The reason is that the variable start & end strings are hardcoded when cookiecutter is looking for the template directory (see here). This means that cookiecutter always looks for {{ and }} when looking for a template directory, which should actually be variable_start/end_string in the case of overriding them.

This is the same behavior as this closed issue #1736 in which the root problem was not resolved.

I have made a PR addressing this issue, and am very open to feedback #1963

What I've run:

cookiecutter .

in a project with cookiecutter.json

    ...,
    "_jinja2_env_vars": {
        "variable_start_string": "{%{",
        "variable_end_string": "}%}"
    }

I have updated my PR with an additional fix regarding the usage of these placeholders.

Looking forward to your feedback 🙂

I'm running into this same issue. It would be very useful for using cookiecutter with React projects where {{ can possibly show up in many places. Thanks @sacha-c for looking into it!
