## `getSelectors`

### Signature

```solidity
function getSelectors(string calldata artifactPath) external view returns (bytes4[] memory selectors);
```

### Description

Returns every function selector declared in the ABI of a compiled contract artifact.

You can identify the artifact by contract name, source path, compiler version, build profile, or a direct path to its JSON file. Use a more specific identifier when multiple artifacts match.

### Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `artifactPath` | `string` | Contract or artifact identifier |

### Returns

| Type | Description |
|------|-------------|
| `bytes4[]` | Function selectors from the artifact ABI |

### Example

```solidity [test/RecentCheatcodes.t.sol]
// [!include ~/snippets/projects/cheatcodes/test/RecentCheatcodes.t.sol:get-selectors]
```

### Supported Formats

Artifact identifiers include:

```text
Counter
Counter:0.8.30
Counter:optimized
src/Counter.sol
src/Counter.sol:Counter
src/Counter.sol:Counter:0.8.30
src/Counter.sol:Counter:optimized
out/Counter.sol/Counter.json
```

### Gotchas

* The call reverts when no artifact matches or when an identifier matches multiple artifacts.
* Reading a direct `.json` path requires read permission for that path. Identifiers resolved from the current build's in-memory artifact list do not.
* The result comes from the artifact ABI, so it excludes functions that are not present in that ABI.
