13:30 <sleepydog> anyone got an example of a Cmdliner.Arg.t that accumulates repeated values of the same flag? The vflag_all examples show how to choose between different flags

13:31 <sleepydog> I'm trying to have a command line like awk's -v flag, e.g `mycommand -v var1=foo -v var2=bar ...`

13:35 <sleepydog> ah, i think i figured it out

17:21 <discocaml> <lima.leonardo> Hi. I am having some trouble with Eio and could use some help. I am trying to specify three fibers: one that executes an external process; one that writes to the stdin of the external process; and one that reads from the stdout of the external process, as follows:

17:21 <discocaml> <lima.leonardo> ```ocaml

17:21 <discocaml> <lima.leonardo> let exec (stream: in_channel) =

17:21 <discocaml> <lima.leonardo> let ( / ) = Eio.Path.( / ) in

17:22 <discocaml> <lima.leonardo> Switch.run (fun sw ->

17:23 <discocaml> <lima.leonardo> Just realized that I should have properly have asked in a different channel. Sorry for the long message.

17:32 <discocaml> <yawaramin> maybe #concurrency

17:32 <discocaml> <lima.leonardo> Thanks. Will repost it there.

18:31 <dh`> here's probably as good as anywhere
