It renders list variable only as first item of it

• Cookiecutter version: 2.4.0
• Template project url:
• Python version: 3.10
• Operating System: ubuntu

Description:

When i have something like this:

animal:
  fly: [bird]
  walk: [cat]
food: [meat, worms]

I try to put this in cookiecutter template generation:

    """Generate usecase project structure from cookiecutter template."""
    rich_print("Generating project from cookiecutter template.")
    cookiecutter(
        template=str(ROOT_PATH / "template"),
        no_input=True,
        extra_context={
            "animal": config["animal"],
            "food": config["food"],
 
        },
    )

Then in post_gen_project.py i try to tweak a bit:

ANIMAL: str = "{{ cookiecutter.animal }}"
FOOD: str = "{{ cookiecutter.food }}"

print(ANIMAL)  # -> {"fly": ["bird"], "walk": ["cat"]}
print(FOOD) # -> meat

Its crazy, i have never seen such a thing, like there is no place in between that i reference these variables, and when variable is type of list it only takes first time with cookiecutter, checked everystep.. No idea what can i do more

I literally run into the same problem just now and I am so glad there is an open issue. After digging, I found that
at this point the context is wrong.

cookiecutter/cookiecutter/main.py

Lines 183 to 186 in 2402048

	with import_patch:
	result = generate_files(
	repo_dir=repo_dir,
	context=context,

I am still trying to understand the source code, there is context["cookiecutter"] which stores the first element of a list while there is an internal one context["_cookietcutter"] that keep the original list.

It's most likely this function is buggy.

cookiecutter/cookiecutter/prompt.py

Lines 233 to 240 in 1669f0d

	def prompt_for_config(context, no_input=False):
	"""Prompt user to enter a new config.
	:param dict context: Source for field names and sample values.
	:param no_input: Do not prompt for user input and use only values from context.
	"""
	cookiecutter_dict = OrderedDict([])
	env = StrictEnvironment(context=context)

Which has this logic of treating list as a choice.

cookiecutter/cookiecutter/prompt.py

Lines 268 to 272 in 1669f0d

	if isinstance(raw, list):
	# We are dealing with a choice variable
	val = prompt_choice_for_config(
	cookiecutter_dict, env, key, raw, no_input, prompts, prefix
	)

[noklam]

As a workaround, use {{ _cookiecutter.<var> }} instead of {{ cookiecutter.<var> }}. This preserve the original list, right now I think cookiecutter assume a list is a choice so it will only return one of the choices.
