Source code directives to ignore lines

There are a couple of ways (as demonstrated below) to nudge Aderyn to skip reporting on certain lines.

Example

Consider the following code:

// aderyn-ignore-next-line(centralization-risk, state-change-without-event)  
function withdraw() external onlyOwner {  
    uint256 l = s_funders.length;  

    // aderyn-ignore-next-line(costly-loop)  
    for (uint256 funderIndex = 0; funderIndex < l; funderIndex++) {  
        address funder = s_funders[funderIndex];  
        delete s_addressToAmountFunded[funder];  
    }  
    ...  
}  

In this snippet, Aderyn flags the withdraw() function for centralization risk and state change without an event. If you, as the developer, are aware of these risks and accept them, you can suppress these warnings using one of the following methods:

Ignore the next line

Place the directive above the problematic line

// aderyn-ignore-next-line(detector-name)

Ignore the current line

Place the directive on the same line:

// aderyn-ignore(detector-name)  

Ignoring All Detectors

If you want Aderyn to skip a line entirely, regardless of the detector, you can use:

// aderyn-ignore  

// aderyn-ignore-next-line  

Note that in this case, you do not need to specify the detector name in parentheses.

Aderyn sometimes reports issues that are false positives in addition to legitimate issues.

Since it helps to make a semantic separation between directives that are for ignoring legitimiate issues and false positives we have introduced a new directive which behaves exactly the same way as the above mentioned ignore directive but it can be invoked by replacing the word ignore with fp Example

// aderyn-fp(detector-name)

All other variants shown above will work with fp

This allows developers to remember to revisit the false positives before launching their protocol.
