Note that this validation runs both after the file is uploaded and after CarrierWave has processed the image. If your base uploader includes a filter to resize the image then the validation will be run against the resized image, not the original one that was uploaded. If this causes a problem for you, then you should avoid using a resizing filter on the base uploader and put any specific size requirements in a version instead.

So instead of this:

require 'carrierwave/processing/mini_magick'

# This gist contains pre-commit hooks to prevent you from commiting bad code or to the wrong branch.
# There are six variants that I have built:
# - pre-commit: stops commits to master/main/develop branches.
# - pre-commit-2: also includes a core.whitespace check.
# - pre-commit-3: the core.whitespace check and an EOF-newline-check.
# - pre-commit-4: only the core.whitespace check.
# - pre-commit-5: elixir formatting check.
# - pre-commit-6: prettier formatting check.
# Set the desired version like this before proceeding:

Exporting (iCloud) Keychain and Safari credentials to a CSV file

Update (October 2021)

Exporting password + one-time code data from iCloud Keychain is now officially supported in macOS Monterey and Safari 15 (for Monterey, Big Sur, and Catalina). You can access it in the Password Manager’s “gear” icon (System Preferences > Passwords on Monterey, and Safari > Passwords everywhere else), or via the File > Export > Passwords... menu item). You shouldn't need to hack up your own exporter anymore.

Original, Obsolete Content (2014)

After my dad died, I wanted to be able to have access any of his online accounts going forward. My dad was a Safari user and used iCloud Keychain to sync his credentials across his devices. I don’t want to have to keep an OS X user account around just to access his accounts, so I wanted to export his credentials to a portable file.
