How to use the project check-config command

In progress

The Great Expectations CLI is no longer the preferred method for implementing and configuring Great Expectations. This topic will be updated soon to reflect this change. For more information, see A fond farewell to the CLI.

To facilitate this substantial config format change, starting with version 0.8.0 we introduced project check-config to sanity check your config files. From your project directory, run:

great_expectations project check-config

This can be used at any time and will grow more robust and helpful as our internal config typing system improves.

You will most likely be prompted to install a new template. Rest assured that your original YAML file will be archived automatically for you. Even so, it's in your source control system already, right? ;-)
