Custom extensions

[dadyarri]

How to to use custom extensions in template directory without changing pythonpath?

In my template (https://github.com/dadyarri/lab-work-template) i have extensions folder in there one python file with jinja extension, which used in one of the generated files.

cookiecutter.json have correct link to this extension:

but when i try to run cookiecutter with this substitution {% cookiecutter.file_name|to_camel %} i got this:

  File ".\tests\test_{{cookiecutter.file_name}}.py", line 3, in template
jinja2.exceptions.TemplateSyntaxError: Encountered unknown tag 'cookiecutter'.
  File ".\tests\test_{{cookiecutter.file_name}}.py", line 3
    class Test{% cookiecutter.file_name|to_camel %}:

this with this substitution {{ cookiecutter.file_name|to_camel }}

File ".\tests\test_{{cookiecutter.file_name}}.py", line 3, in template
jinja2.exceptions.TemplateAssertionError: No filter named 'to_camel'.
  File ".\tests\test_{{cookiecutter.file_name}}.py", line 3
    class Test{{ cookiecutter.file_name|to_camel }}:

Hey @dadyarri 👋 ,

Cookiecutter needs to import the extension module; if the module is not in your python path, it will raise an ImportError under the hood.

So the options, IMHO, are:

• change the python path
• install your template as a package and use the full package like es. : "_extensions": ["lab_work_template.extensions.to_camel.ToCamelCaseExtension"]
• wait for https://github.com/cookiecutter/cookiecutter/pull/1240/files

We hope to include this feature shortly.

Thanks 🙏
