Key Features

The key features of sf_git include:

• Snowsight Authentication: Supports both SSO and password modes for secure access.
• Worksheets Push and Fetch: Allows seamless synchronization of local and Snowsight worksheets.
• Configuration: Configurable through CLI commands for personalized setup.

Installation and Configuration

To install and configure sf_git, follow these steps:

$ pip install sf_git==1.3.1
$ sfgit config --git-repo <path_to_git_repo>
$ sfgit config --save-dir <path_to_worksheets_persistency_directory>
$ sfgit config --account <your_snowsight_account_id>
$ sfgit config --username <your_snowsight_login_name>
$ sfgit config --password <your_snowsight_password>


Usage Workflow

The sf_git tool follows a straightforward workflow for managing worksheets:

1. Start session: Upload worksheet from the local branch to Snowsight.
2. Modify and Validate: Test and update on Snowsight.
3. End session: Fetch modified worksheets back to the local branch and commit changes.

$ sfgit fetch
$ sfgit commit -m "Your commit message"


Limitations

The sf_git tool has certain limitations:

• Synchronization respects case sensitivity and folder architecture: Users need to be mindful of case sensitivity and folder structure when synchronizing worksheets.
