Summary

(This is likely not a finished plugin, but a grounds for discussion around this feature.)

In logEvent, I would like to be able to distinguish between errors that I already opted out via "use no memo"/"use no forget" and new, unhandled errors.

How did you test this change?

No tests yet, I want to know if this is something worth pursuing first before I put more work into this.

Greptile Overview

Greptile Summary

This PR adds an optedOut boolean field to CompileErrorEvent to distinguish between compiler errors that were explicitly opted out using directives like "use no memo" or "use no forget", versus new unhandled errors. The change enables better telemetry by allowing consumers to filter error logs based on whether they were intentionally suppressed.

• Added optional optedOut field to CompileErrorEvent type definition
• Modified logError function to accept an optedOut parameter and include it in logged events
• Passes true when logging errors for functions with opt-out directives, false for all other error cases

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is simple, well-scoped, and backwards-compatible. The optedOut field is optional, so existing logger implementations won't break. The logic correctly distinguishes between opted-out errors (when directives.optOut != null) and regular errors, properly threading the boolean through the call chain.
• No files require special attention
