hello, I am having issues trying to install 'mysql2' gem on windows 10. I tried supplying the mysql include and lib folders for "mysql server 8.0", "connector c++ 8.0" and "mysql-connector-c-6.1.11"

@weaksauce: Was able to get it to work. My problem was, that my specs were wrapped in a Module . Removed the Module and it works perfectly now. Thanks for your hint with the solargraph download-core ; yard gems ; solargraph bundle ; sequence of commands. Something solid to hold on to. :)

So I'm still confused how the ruby ecosystem handles semver compliant versions that include a prerelease number. Rubygems recommends 1.0.0.alpha.1, but the semver standard would use 1.0.0-alpha1. What would happen with a semver-compliant version string? Will it still be handled as a prerelease by all the Ruby tools?

does ruby support the separation of declaration and implementation of code in separate files the way .h header files and .c code files work in C?

John_Ivan: No.
<John_Ivan>
I see. thanks.
<adam12>
I mean, you could just define empty method bodies if you wanted...
<adam12>
I'm sure it would be fine, but might warn.
<John_Ivan>
yeah. cheers.
<adam12>
Paired with Ruby 3 endless methods, it might be fairly close.
<adam12>
def method()= nil; def other_method()= nil; then in other fine, def method(); implementation.
<adam12>
If you're at that point, I'd probably just use RBS. But I am not sure of your ultimate use case.

adam12, what's RBS? my goal is just organization.

hobby project. I just want to be clean.
<adam12>
John_Ivan: It's a file format for Ruby 3 type support that defines the method signatures.
<John_Ivan>
oh nice
<adam12>
Technically it's use for type checking, but if you wanted to just use it for documentation and ignored the errors it might be OK too.

If I do `string.unpack(format)` the result would read a certain amount of bytes from the string, for example "LCCCC" would be 8 bytes. Is there a way to find out the size of that packed format?
<felipec>
So for example I could do `io.read(sizeof("LCCC"))`
