AnyEvent::Subprocess::Easy - wrappers around AnyEvent::Subprocess to save typing in simple cases
version 1.102912
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 don't work quite the way you want, it is not too hard to use AnyEvent::Subprocess directly.
We use Sub::Exporter here, so you can customize the exports as appropriate.
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 doesn't exit cleanly.
qx_nonblock
recv
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).
exec
exit 0
Not enough "easy" stuff here yet. Please contribute your common patterns!
