How to get funID?

Question

need help to get the correct funcID. I've Tried many ways. Will be glad to get your help. Thanks!

slugSha256() {
  slug=$(echo -n "$1" | sha256sum | cut -d' ' -f1)
  echo -n $((16#"${slug:0:8}"))
}
functionHash() {
  hash=$(slugSha256 "$(echo -n "$1" | sed 's/ //g')")
  if [[ "$1" == *constructor* ]]; then hash=$((hash ^ (2 ** 31))); fi
  printf '0x%x' "$hash"
}
functionID() { functionHash "$1v2"; }

`

functionID "main()(string)" # 0xb0992770
functionID "redeem(uint256, string, uint256)()" # 0x58160fa0
functionID "constructor()()" # 0x68b55f3f

Answer 1

foo.sol

pragma ever-solidity >= 0.64.0;
contract foo {
 constructor() public {}
 function main() public returns (string) {}
 function redeem(uint256 a, string b, uint256 c) public {}
}

via everdev npx everdev sol update

~/.everdev/solidity/solc --function-ids foo.sol

via sold: sold --function-ids foo.sol

out:

{
  "constructor": "0x68b55f3f",
  "main": "0x30992770",
  "redeem": "0x58160fa0"
}
