Can't get the example to works #3
Description
Hi there,
I can't get ctrl+g to print hello world in interactive python shell as described in the example.
~/Documents/Git/rl_custom_function $ cat ~/.inputrc
$include function hello_world /tmp/hello_world.so
"\C-g": hello_world
~/Documents/Git/rl_custom_function $ rustc example/hello_world.rs -o /tmp/hello_world.so
~/Documents/Git/rl_custom_function $ cargo build --release --target-dir /tmp

write(2, "hello_world /tmp/strace\10\10\10\10\10\10\10\10\10"..., 35) = 35Any ideas ?
