copier VS cookiecutter

When the internal model and the API model are pretty much the same, you might simply copy the result from one struct to another using e.g. https://github.com/jinzhu/copier

An alternative is to use a reflection based struct copier library or a codegen struct copier library

I think using the yaml library directly would be a lot easier. You could then unmarshal both configs to a struct and use something like copier to update the values.

However, if you don't want to bother, I suggest to take a look at https://github.com/jinzhu/copier which is more extensive and works with slices and pointer types.

Sometimes I use this to abstract boilerplate https://github.com/cookiecutter/cookiecutter

It can use a repo as a template.

It supports some interactive questions to choose options but mostly it is jinja templates.

Having libraries would be another option.

Install the cookiecutter package using the following command:

Consider taking a look at cookiecutter to generate projects from templates. There is also cookiecutter-django. As for your environment variables you should have an example .env file containing all the environment variables required by your project (without setting them) that can be safely pushed into your repository for you and other developers to copy into the actual .env file that'll be used by your project (add this file to .gitignore)

The Python Cookiecutter library revolutionizes project development by offering streamlined approach to creating template projects and improving developer experience.

We use cookie cutter templates (the Python project, https://github.com/cookiecutter/cookiecutter ), we prompt for the module & version etc

Why not use cookiecutter or a similar tool designed for making these sorts of project templates?

Is it common? I don't know. Is it useful? Absolutely. There is a tool called cookiecutter that allows you to define your own setup. For example, my cookiecutter setup for a python library is here. You can see what it's like by first installing the cookiecutter cli and then running

Also cookiecutter.

Visual Cookiecutter enhances the functionality of cookiecutter by offering unique features such as required fields, conditional input parameters, optional descriptions, and the ability to fix mistakes easily. This package seamlessly integrates with cookiecutter so that all existing templates work out-of-the-box.
