Create folder if condition is met

[roaldarbol]

I want to create a folder if a certain condition is met. Currently I've got a solution that works on Mac, but I get an error on Windows. I don't really think it's a bug (but if it is, we can transfer to issues), but rather that I can't find out from the docs how to do it properly.
The project is here in case anyone wants to have a closer look.

The crus is that I want to have a .vscode/settings.json be generated only if the user indicates that they use VS Code. I've tried a few different things:

• {% if "Visual Studio Code" in ide %}.vscode{% endif %}.jinja, settings.json
• {% if "Visual Studio Code" in ide %}.vscode{% endif %}, settings.json
• {% if "Visual Studio Code" in ide %}.vscode{% endif %}, settings.json.jinja
• {% if "Visual Studio Code" in ide %}.vscode{% endif %}.jinja, settings.json.jinja

It all works fine on MacOS, but on Windows it generates an error, the important part being:

Stderr:       | error: invalid path '{% if "Visual Studio Code" in ide %}.vscode{% endif %}/settings.json.jinja'

Here's the entire error message - I run copier with pixi exec, but that shouldn't really matter:

I also tried putting a conditonal statement in the exclude section of copier.yaml but couldn't make that work.

Double quotes are invalid path characters on the annoying operating system. Try single quotes instead :) (your second solution)

[roaldarbol]

That did it! Thanks! :-D

[kir0ul]

I had the same issue and that fixed it, thanks!
