Dolt is a SQL database that you can fork, clone, branch, merge, push and pull just like a Git repository. Connect to Dolt just like any MySQL database to read or modify schema and data. Version control functionality is exposed in SQL via system tables, functions, and procedures. Or, use the Git-like command line interface to import CSV files, commit your changes, push them to a remote, or merge yo
Working on many projects across multiple identities can be difficult to manage. This is a procedure that leverages git aliases to set an identity at the project level for any arbitrary project. This procedure also implements GPG-based commit signing, which establishes the following security features: Authenticity: The name on the commit really is the author of the code. Integrity: Neither the code

At a certain point one of your messages got mislabled and you try to understand why. You scroll through that horrible mess of filters, you wish you could find-and-replace stuff, test the changes on your fi
