ProjectName normalization

[fcx-mrogez]

I wanted to use project name with dots "." in it ("my-compose-app-1.2.3"), but the ProjectName Normalization procedure doesn't allow dots and remove them, which is inconvenient:

compose-go/loader/loader.go

Line 700 in dbfe619

r := regexp.MustCompile("[a-z0-9_-]")

I don't see in the specification such restriction about dots in the name: https://github.com/compose-spec/compose-spec/blob/main/04-version-and-name.md#name-top-level-element

I know I can Skip normalization, but doing so will also remove the creation of default network which I rely on.

So are dots acceptable in the name ? Should the specification be modified to include what are acceptable names ?

Normalization is required as project name is used as prefix for docker resources, so those restrictions.
. anyway should not be an issue, need to check if there's any other reason this is rejected

Ok good to know. Even better if "." can be accepted :)
