Skip directory if name is empty

See original GitHub issue

We are looking to have a configuration like this:

things:
  thing1:
    name: name1
    type: one
  thing2:
    name: name2
    type: one
  thing3:
    name: name3
    type: two

And from it we’d like to stamp out a particular folder for each thing based on its type field. I’m wondering if any thought has been given to a feature like this?

One approach would be to support conditional directories. If the name evaluates to empty, then omit it and all its content from being copied. With this, its not ideal, but we could create a fixed number of folders:

- [[things.thing1.name if things.thing1 is not none]]
- [[things.thing2.name if things.thing2 is not none]]
... etc.  (I'm not 100% on that jijna syntax, but conceptually make the dir name empty if you don't want to render it).

Another approach would be somehow support for loops in directory names, but I’m uncertain of exactly how that might look right now.

Has this ever come up before? Is there a feature or enhancement around this that copier would be willing to accept?

A slightly different use case but I needed to have conditional folders today.

My use case: I have a django template structure where I want templates folder to be contents of either bs5 or tailwind depending on the answer.

For this purpose I have two folders in copier template. One contains bootstrap templates. Second contains tailwind templates.

Didn’t work I tried with this:

[%if project_type == 'bs5' %]templates[%endif%]
[%if project_type == 'tailwind' %]templates[%endif%]

If I specify tailwind, then contents that were inside the bs5 folders get copied to parent as blank path is specified.

Worked I found a trick that worked for me. Sharing that in case someone needs it. I noticed that excludes contains __pycache__. So when I wanted to skip the folder, I named it __pycache__. Seems to do the trick.

This works for me:

[%if project_type == 'bs5' %]templates[%else%]__pycache__[%endif%]
[%if project_type == 'tailwind' %]templates[%else%]__pycache__[%endif%]

Hope this helps someone. -A

Ah, but that’s for a file, not for a dir. However, I see that in the same test we have https://github.com/copier-org/copier/blob/534a888a0ae2222ab2352fe4b9dcfa1fbe82a64a/tests/test_copy.py#L61 which really is our test case.

Thus this should be closed, please reopen if it happens again, thanks everyone. 😊
