oh you will very much want to do this at the head of your mix task or else you’ll be wondering why nothing works:
Application.ensure_all_started(:hound)
Chromedriver.ensure_running()
# linux, very hacky, MacOS - ymmv
@spec ensure_running(non_neg_integer) :: :ok
def ensure_running(sleep_time \\ 500) do
{ps, _} = System.cmd("ps", ["aux"])
unless ps =~ "chromedriver" do
chromedriver_executable = System.find_executable("chromedriver")
{:ok, _pid} = Task.start(fn ->
System.cmd(chromedriver_executable, [], stderr_to_stdout: true)
end)
Process.sleep(sleep_time)
end
:ok
end
