envBytes32
Signature
function envBytes32(string calldata key) external returns (bytes32 value);
function envBytes32(string calldata key, string calldata delimiter) external returns (bytes32[] memory values);
Description
Read an environment variable as bytes32
or address[]
.
Tips
- For arrays, you can specify the delimiter used to separate the values with the
delimiter
parameter.
Examples
Single Value
With environment variable BYTES32_VALUE=0x00
,
string memory key = "BYTES32_VALUE";
bytes32 expected = bytes32(0x0000000000000000000000000000000000000000000000000000000000000000);
bytes32 output = cheats.envBytes32(key);
assert(output == expected);
Array
With environment variable BYTES32_VALUES=0x7109709ECfa91a80626fF3989D68f67F5b1DD12D,0x00
,
string memory key = "BYTES32_VALUES";
string memory delimiter = ",";
bytes32[2] memory expected = [
bytes32(0x7109709ECfa91a80626fF3989D68f67F5b1DD12D000000000000000000000000),
bytes32(0x0000000000000000000000000000000000000000000000000000000000000000)
];
bytes32[] memory output = cheats.envBytes32(key, delimiter);
assert(keccak256(abi.encodePacked((output))) == keccak256(abi.encodePacked((expected))));
