Thanks for the reminder!

This can be updated with check marks for:

• kaitai_struct_tests
• kaitai_ci_ui

Now that the tests are licensed kaitai-io/ci_targets#4 can be merged and checked off, too.
Edit: ci_targets has the prepare-* files in the repo so it's not as easy as that.

[GreyCat]

I would actually try to do it another way: let's strip ci_targets from everything but generated code + minimal possible set of CI instructions, and clearly mark it as technical repo, derivative of the compiler + tests + runtimes?

[cherue]

SGTM. So that would mean moving all the prepare-* scripts to the test repo and using the config from the test repo too, right?

[GreyCat]

Yep. Ideally, I'd even want to switch to into the mode when we won't depend on any particular proprietary CI's init/prepare instructions and just use our own, say, Docker containers, so exact CI test runs can be easily reproducible on local machine.

Extracted this as a separate idea: #714
