13:36 <dr_df0> hi!

13:36 <dr_df0> hi all! quick question, is there a better way than using mutable ref list to capture query results from the Sqlite3.exec callback function:

13:36 <dr_df0> like in the pseudo code:

13:36 <dr_df0> let result = ref []

13:36 <dr_df0> exec db sql ~cb:( fun row _ -> match row.(0) with Some a -> result := a :: !result | _ -> () )

13:45 <freyr69> dr_df0: it seems not. You could use stack, tho

13:45 <freyr69> Stack.pop

13:45 <freyr69> *push

13:48 <dr_df0> freyr69: thanks!

21:02 <orbifx> hello all

21:03 <orbifx> anyone here familiar with the lwt_sequence replacement situation? companion_cube

21:03 <orbifx> I see mirage has gone down the dllist way

21:05 <orbifx> companion_cube: also `opam search lwt-pipe` doesn't find lwt-pipe

21:06 <companion_cube> might not be released

21:10 <orbifx> companion_cube: got a minute to catch me up? I came back to use lwt.sequence and found everyone running away :P

21:10 <companion_cube> well I can dicuss, but I don't really have time to work on that

21:10 <companion_cube> it needs more testing, always :/

21:10 <companion_cube> (or actual use in prod)

21:15 <orbifx> What are the candidates in play now to substitute sequence?

21:15 narimiran has quit [Ping timeout: 272 seconds]

21:15 <companion_cube> lwt.sequence? no idea really

21:15 <orbifx> I need to spawn lwt threads (promises?) that communicate with each other by pushing messages to each other
