06:51 <ehirdoy1> I'm trying to get rid of Unix dependency in some general package, which uses Unix.gettimeofday (). Should I replace gettimeofday with Mirage_clock.PCLOCK.now_d_ps to support Unix && Hvt at once?

09:01 <hannes> ehirdoy1: yes, the common pattern is to functorize them over (P : Mirage_clock.PCLOCK) and use "P.now_d_ps ()" in the code. then the client has to instantiate that functor and pass their clock implementation.

09:02 <hannes> another option is to pass a function (unit -> Ptime.t, or even only Ptime.t) to the library, then there's no functor needed

09:04 <hannes> I've not yet found a good rule of thumb what to use when, both are very explicit, I usually like passing the function/current timestamp better unless the module is already functorized (since functors are pretty heavy-weight in my brain -- and I like to be able to read and explain my code even in the morning before my first coffee)

23:47 <atagunov> hi, I've seen "Metaprogramming with ML modules in the MirageOS" mentioned a couple of times online. What does it actually mean? Is Mirage written in usual OCaml? Does it then have these metaprogramming facilities outside of Mirage context? Thx!

23:50 <atagunov> - not entirely sure I am on the right channel for a generic question like this but this is the only mirage channel I found
