guard-s3 is a simple guard library that syncs local directories with S3 as files are changed.

This is a sample Guardfile that will automatically upload all files in the Guard watchdir directory into the specified S3 bucket. By default, watchdir is the directory from which guard was called, but it can be specified using the --watchdir/-w parameter. See the guard main documentation for details.

opts = {
  :access_key_id      => 'ACCESS_KEY_ID_XXXXXX',
  :secret_access_key  => 'SECRET_ACCESS_KEY_XXXXXXXXXXXXXXXXXXXXXX',
  :bucket             => "mybucket",
  :s3_permissions     => :public_read
}

guard 's3', opts do
  watch(/.*/)
end

prefix is supported as a an option prefix to the key created on S3. e.g. /prefix/path/to/file.txt

• guard
• aws-sdk

• Added prefix to prefix S3 key.
• Compare file etag and upload if different (or not present).
• Support Guard v2.
• Switch to using Amazon aws-sdk for Ruby.

• Fixed watchdir behavior. Guard-s3 will now watch and upload from the directory path specified in the Guardfile relative to the guard watchdir.
