Manual Reference Pages - ANYEVENT::SUBPROCESS::EASY (3)
AnyEvent::Subprocess::Easy - wrappers around AnyEvent::Subprocess to save typing in simple cases
use AnyEvent::Subprocess::Easy qw(qx_nonblock);
my $date = qx_nonblock(date)->recv;
I was writing some examples and noticed some patterns that came up
again and again, so I converted them to functions. These are opaque
and non-customizeable, but might be helpful if you want to do
something common without a lot of typing. If they dont work quite
the way you want, it is not too hard to use AnyEvent::Subprocess
We use Sub::Exporter here, so you can customize the
exports as appropriate.
qx_nonblock( CW$cmdline | CW@cmdline )
qx_nonblock works like qx, except that it returns a condvar that
you recv on to get the captured stdout. The recv will throw an
exception if the process you run doesnt exit cleanly.
You can pass in one string for the shell to interpret (like exec),
or you can pass in a list of arguments (passed directly to exec).
You can also pass in a coderef if you like; it will be called with an
undefined number of arguments in the child process (and should exit 0
if it is successful).
Not enough easy stuff here yet. Please contribute your common
