I was interested in creating a template that adds a suffix to all the input wires in an instance. I was having trouble figuring it out based on the examples. Wilson helped me out, so I am posting the result here:

/* digital_block AUTO_TEMPLATE (
.(.) (\1@"(if (equal vl-dir "output") nil "_sh")"[]),
);/
dig_block(/autoinst/);

turns into:
dig_block(/autoinst/
// Outputs
.out1 (out1),
.out1 (out2[3:0]),
...
// Inputs
.in1 (in1_sh),
.in2 (in2_sh[3:0]),
...);

Thanks.
