Question 1

How do I integrate errlog with an existing logger like logrus?

Accepted Answer

Set the PrintFunc in the Config struct to your logger's printf method, as shown in the custom example using logrus.Printf. Ensure the format string handles newlines appropriately for clean output.

Question 2

Is errlog or pkg/errors better for Go error debugging?

Accepted Answer

Errlog focuses on real-time debugging with source context and stack traces, while pkg/errors is for error wrapping and propagation. Errlog is ideal for immediate insights during development, whereas pkg/errors suits error chain management.

Question 3

Can I disable errlog for specific errors or code sections?

Accepted Answer

Errlog operates globally per logger instance; selective disabling requires creating multiple logger configurations or using environment variables to conditionally enable features, which isn't built-in.

Question 4

Does errlog handle errors in concurrent Goroutines well?

Accepted Answer

Errlog logs errors with stack traces that include goroutine information, but it doesn't aggregate or specifically manage concurrent errors, so each error is logged independently in its goroutine context.

Question 5

How current is errlog? The README mentions last update 2019.

Accepted Answer

The project shows signs of staleness with warnings about outdated documentation. Check GitHub for recent commits or issues to assess maintenance, as it might not have active updates.

Question 6

What's the performance hit when using errlog in dev vs production?

Accepted Answer

In development, enabling all features adds noticeable overhead due to stack trace generation and source printing. In production, use no-op mode to reduce this to near-zero, similar to standard error checks.
