For example: function_factory func1 func2 func3 will create three functions that just have the passed names without doing anything.
These birthed functions should be exported with like export -f function_name to make sure they are available in the same environment of function_factory .
Maybe you can use eval:
function generate_hello {
eval "function say_hello_to_$1 { echo hello $1; }"
}
Then run it:
$ generate_hello world
$ say_hello_to_world
hello world
It could be something like that:
#!/bin/bash
function function_factory()
{
while [ $# -ne 0 ]
do
eval "
function $1()
{
echo \"my name is $1\"
}
"
shift
done
}
function_factory fun1 fun2 fun3
fun1
fun3
output:
$ ./test
my name is fun1
my name is fun3
This is about as minimal as I can get:
factory() { for f; do eval "$f() { :; }"; done; }
Then:
$ factory f{1..3}
$ type f1 f2 f3 f4
f1 is a function
f1 ()
{
:
}
f2 is a function
f2 ()
{
:
}
f3 is a function
f3 ()
{
:
}
bash: type: f4: not found
