LLM Memory Gmail Loader

The LLM Memory Gmail Loader is a loader plugin designed for the llm_memory gem. It enables the retrieval of emails using the Gmail API. To use this plugin, please ensure you have the llm_memory gem installed.

              :gmail,
              emails: ["my@example.com"],
              query: "label:sent",
              limit: 10
            )

GOOGLE_PRIVATE_KEY
GOOGLE_CLIENT_EMAIL
GOOGLE_CLIENT_ID

2. Add the following configuration block in your initializer:

LlmMemoryGmailLoader.configure do |config|
  config.google_project_id = "<your_google_project_id>"
  config.google_private_key_id = "<your_google_private_key_id>"
  config.google_private_key = "<your_google_private_key>"
  config.google_client_email = "<your_google_client_email>"
  config.google_client_id = "<your_google_client_id>"
end
