Library function is public but deploying automically

Question

According to the documentation If a library has only internal functions then the library is included in the contract that uses it. There is no need to deploy a separate contract for the library. But I a have public function in a library that's deploying automatically with the contract. But it supposed to be deployed separately cause I was accessing a public function.

Here is my code:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.3;

library math{
    function max(uint x, uint y) public pure returns (uint)
        {
            return x >= y ? x : y;
        }
}


contract test{
    function testMax(uint x,uint y) external pure returns (uint) {
        return math.max(x,y);
    }
}

Here I can access the max function without deploying the math library. What's the reason behind it? Note: I am using remix IDE

This comes down to the compiler that you use. Remix IDE will deploy libraries automatically according to the docs - see here.

There is an autoDeployLib attribute in the artifact JSON file of the calling contract. You can set that to false if you'd like to disable this behaviour for a particular contract/library pair. The docs I linked also explain this.

There is also a very similar question I found that might help Why can I use Linked Libraries on Remix IDE without deploying them first?
