It's is unclear what you are asking for. The Julia Base library includes a high-performance, cross-platform framework for responding to file change events on disk. (see base/poll.jl)
Interprocess communication is done through the creation of a named pipe. (see base/spawn.jl for examples) popen is unrelated to fork, select, or file notification. although the equivalent call in julia is more object-based, around the Cmd object and backtick (`) notation, and functions such as run, spawn, and open On Sun, Jun 15, 2014 at 7:54 PM, Alireza Nejati <[email protected]> wrote: > It's my impression that to do this sort of stuff you should use Julia's > built-in process creation/communication facilities.
