💡 There is a safeguard for this problem.

@szepeviktor Thanks for the pull request and linking to your workflow file.

The generated zip file contains a few files that are listed in the .gitignore file. By default git archive ignores these files, do you know if there is a method that will allow safe-svg to include these files when generating the zip file via git archive?

The affected files are:

• built assets in the /dist directory
• production assets included in the /vendor directory

I've hit a few road-blocks trying to figure it out, so would value any input.

There is an option for that: https://git-scm.com/docs/git-archive#Documentation/git-archive.txt---add-fileltfilegt

BTW .gitignore is unrelated to .gitattributes

Isn't this covered by the .distignore file?

Maybe.
Composer uses GitHub ZIP, those are not affected by distignore.
