This action works to prevent both:

• Large files that are not LFS tracked
• Files that are LFS tracked

from being checked-in in non-pointer format/not stored in LFS. The latter happens if the client does not have git-lfs installed.

This action scans files in commits of a pull request and will mark the pull request as failed, add a lfs-detected! label and reply with an issue comment if any of the following is true about any of the pull request files:

• The file size is greater than the configured file size limit threshold.
• The file is tracked in LFS but is being checked-in as a regular file
  • the current implementation of this check is that the file has git attribute filter: lfs but does not contain the string version https://git-lfs.github.com/spec/v1'

Note: Remember to configure the branch protection rule and select the LFS-warning status when you enable the Required status check to pass option.

Required, set's the file size limit threshold. Accepts b (bytes), mb (megabytes) and gb (gigabytes) as units of measurement, if omitted interprets as bytes.

Default 10mb.

Optional. Takes a valid GitHub Token from the Repo by default.

Optional. A newline delimited list of glob patterns that match checked in files to exclude form LFS Warning.

Returns an array of possible detected large file(s)
