Here is a #golang challenge for you! 🤓
Without modifying my package named "puzzler", can you create, in the main function, a variable of (non-exported) type puzzler.config? Playground: https://go.dev/play/p/hSSRfbZbjKK
I'll post a solution tomorrow. 😉

@jub0bs Depends on how you define "without modifying my package"

jub0bs Aug 8, 2023

@hexaheximal You can add whatever you want above line 9 (on my screenshot), nothing on or below it. Is that clearer?

hexaheximal Aug 8, 2023

@jub0bs somewhat.

The solution I'm thinking of would be to create a new file in the `puzzler` directory that exports a function to create it.

jub0bs Aug 8, 2023

@hexaheximal Not allowed. Only modify the main package, nothing else. 😉

@jub0bs found a solution using reflection!

I wonder if we can use the `WithTimeoutMs` without reflection to get the desired type. Would gladly take a look at your solution.

@babariviere Nice! Reflection is indeed one possible approach. How about with generics only (no reflection)?

Babar Aug 9, 2023

@jub0bs Ah got it!

So this is what you expected?

@babariviere Yes, well done; you don't even need to call f, though.

I'll talk about what this implies in a future post.

@jub0bs Now that you say it, it’s logic haha.

Will look into it!

@jub0bs Now reading that one makes sense https://infosec.exchange/@jub0bs/110859382493813244
