Common.gitattributes contains very "common" file extensions like tgz:

You can use this or this generator to combine different parts you need (e.g. IDE + Unity + Common + other stuff that are relevant to your project).

Does that work for your scenario?

Is that really the best approach? I thought the idea was to have one gitattributes that should work with most Unity projects. If we need to obtain the .tgz rule from Common.gitattributes, why then have other file formats in Unity.gitattributes like .png or .jpg when they are also available in Common.gitattributes? I could understand it if it was some rare format used in specific projects, but .tgz is how Unity distributes some of its packages.

Common.gitattributes contains very "common" file extensions like tgz:

This is specifically adding lfs to a file that is also in Common. As of right now, only Unity contains lfs entries.

#23 indicates that there wasn't interest in adding lfs globally, but maybe opinions have changed in the last 6 years.

#23 indicates that there wasn't interest in adding lfs globally, but maybe opinions have changed in the last 6 years.

For reference, I converted everything to use lfs in #195 as per #194 (comment). Not sure if anyone has had problems with it but it's possible. Maybe it quietly fails when LFS isn't installed? In that case, we should definitely revert everything to binary.

For this PR, I think it makes sense to include the extension since we already have all those others.
