first, write your code in Go.
package main
var SampleModule = map[string]string{
"hello": "Hello",
}
func Hello(args []string) ([]string, error) {
a := make([]string, 0, len(args)+1)
a = append(a, "hello")
return append(a, args...), nil
}
build it as plugin.
go build -buildmode=plugin sample.go
then load with load stamtement.
load sample # plugin filepath without .so
echo ${hello a ${hello b}}
# Output: hello a hello b
true && echo true
false || echo false
# output
echo hello >out
# append
echo hello >>out
# input
echo hello <in
