[mathisloge]

Describe the pull request

So I don't really know if this is the correct way of adding a older version of a already newer library. But i thought i will give it a try.

pinging @vadi2 as he requested this and might have time to test this as soon as it is ready to use.

waiting for the ci run and then pushing the commits to go back to version 5.4.3

Nice, how would I try this in the project?

currently you could clone the https://github.com/mathisloge/vcpkg with the branch lua 5.1.
But after i push the commits to go back to 5.4.3 you need to follow https://github.com/microsoft/vcpkg/blob/master/docs/users/versioning.md to freeze the version to 5.1

Per policy we don't allow downgrading of libraries. The correct way to accomplish this would be to create your own custom Git registry and push the needed versions to that registry.

You can read our registries blog post that includes an in-depth tutorial. If you need more help setting this up for your project/team please feel free to open a new discussion or contact us by email or Slack/Discord.

So I thought if I'm pushing it back to 5.4.3 the version feature should allow projects to consume the 5.1 version. But since lua started (in vcpkg) with version 5.4.3 only versions beginning with this version are supported in the future?

All older versions have to live in a custom registry?

Thanks for clarifying.

@mathisloge

That's correct. Our current stance is to have missing versions be provided by custom registries; we hope that a federated environment of high-quality custom registries is born at some point in time that can address the shortcomings of the main registry. We also may change our stance on this in the future.

[mathisloge]

@vadi2 Have created a custom registry as @vicroms said with lua versions 5.1, 5.2 and 5.3 since 5.4 and onward will be supported from vcpkg main repo

@vicroms should maybe also close #7713
