@p7-mark How do you handle the case of launch -y here. Those launching stacks in a CI pipeline using full automation need to be assured that this change does not break that automation.

@p7-mark How do you handle the case of launch -y here. Those launching stacks in a CI pipeline using full automation need to be assured that this change does not break that automation.

@alexharv074 when using launch -y, the order of operations is simply printed, and then the launch command is executed without confirmation.

In this example, I run launch -y against a stack group with two stacks (one with obsolete: true):

sceptre launch s3 -y
* During launch, the following stacks will be skipped, neither created nor updated:
s3/bucket-policy

The following operations will occur, in the following order:
Deploy: s3/bucket
Skip:   s3/bucket-policy

[2024-05-27 07:34:22] - s3/bucket - Launching Stack
[2024-05-27 07:34:23] - s3/bucket - Stack is in the PENDING state
[2024-05-27 07:34:23] - s3/bucket - Creating Stack
[2024-05-27 07:34:23] - s3/bucket localtest-s3-bucket AWS::CloudFormation::Stack CREATE_IN_PROGRESS User Initiated
[2024-05-27 07:34:27] - s3/bucket Bucket AWS::S3::Bucket CREATE_IN_PROGRESS
[2024-05-27 07:34:27] - s3/bucket Bucket AWS::S3::Bucket CREATE_IN_PROGRESS Resource creation Initiated

@p7-mark Thanks. I can live with this although I feel like the output in the launch -y case is a bit inconsistent with the original design i.e. not quite Sceptre-y enough! I also think your new code probably belongs in a new private method; it feels to me as if there is too much going on in the print_operations method now.

@p7-mark I have been using this a while now and feel that some work is needed to make the output consistent and clean. During delete I see this:

During launch I then see this:

Similarly, the implementation in the code is inconsistent. You have:
