Prevent Symfony Flex from creating files for some recipes

[guillemcanal]

Context

Symfony Flex is a great tool to get up an running when installing new components, but it has some issues:

We are using PHP to configure packages and components (ex : ./config/packages/doctrine.php, ./config/services.php).

We are using a different directory structure to organize our code were the Application layer is separated from the Domain and the Infrastructure.

Problem

When we use Composer to add or update any project dependency, Flex is noticing that some files are missing and creates them.

We end up having unwanted ./config/**.yaml files and empty directories like so ./src/{Controller,Entity/Repository}/.gitignore.

Possible solutions

• Being able to tell flex that some files are not wanted (for example, by providing glob patterns in the composer extra section).
• Prevent flex from creating files when adding/removing dependencies without recipes or when updating a dependency without a recipe.

Thank you for your consideration
