modules that require 10.10 about hammerspoon HOT 4 CLOSED

been out of touch for a bit -- yeah, versioning of the OS and deprecated functions has been something I've been mulling over lately... I've been avoiding some functionality because of it, but don't have a good way myself to test what's still hanging around...

For modules to be included as part of this new build process, what OS are we targeting? Lately I've been shooting for 10.7 where possible, but even that's getting hard sometimes, as 10.10 has actually removed some things rather than just deprecating them. As for out of band items, anyone have a good process for a makefile or code to check OS version and throw appropriate exceptions or errors? The only one I've seen so far relies on 10.9+ features, but I'll admit to not looking too hard yet!

My opinion is to target the latest OS release only, but I would be fine with:

• Keep the core compatible with older releases (not hard since it's unlikely to change very much)
• Someone makes a way for modules to express a minimum required OS and refuse to load them on older OS versions

I do think that we need to be careful here - I don't want to hold back lots of awesomeness for the majority on the latest OS, because of a tiny minority who are either forced to use an older release, or are refusing to upgrade.

My feelings: okay to require 10.10 for building, maybe help people with building on older versions by skipping modules, so they can still develop/patch. I haven't heard reasons to make core require 10.10, indeed, so if we can limit requiring 10.10 at runtime to specific modules, I'd love that.

I fully agree that holding back on awesome stuff would be bad, and if we run into that, I'm happy to reconsider my feelings :)

I have a hope that we can just catch the dlopen failure, but if not, version checks indeed.

So, we've been going at this for a while and we haven't really run into this issue in practice, afaics. I'm going to close this issue out because I don't think we actually need to do anything at the moment. If that changes, or if anyone disagrees, please re-open :)
