Question 1

How to set up event priorities in the event library?

Accepted Answer

Use the SetPriority method, e.g., ev.SetPriority(event.HP), to assign high priority. This ensures that during simultaneous event triggers, high-priority events are dispatched first, as demonstrated in the README priority example.

Question 2

event library vs libevent: which is better for Go projects?

Accepted Answer

Event is a Go-native alternative with similar performance using epoll/kqueue, ideal for teams wanting libevent-like efficiency without C dependencies. However, libevent has a larger multi-language ecosystem, while event is more lightweight but Go-specific.

Question 3

What platforms does the event library support?

Accepted Answer

It supports Linux, FreeBSD, DragonFly, NetBSD, OpenBSD, and Darwin (macOS), as shown in the platform badges. It does not work on Windows or other non-UNIX systems, limiting cross-platform use.

Question 4

How to handle timeout events in the event library?

Accepted Answer

Combine EvTimeout with other events using the EvTimeout flag, then attach with a duration via ev.Attach(time.Second). The callback triggers when the timeout expires, as shown in the README read/write/timeout example.

Question 5

Is the event library suitable for building an HTTP server?

Accepted Answer

While it provides low-level I/O handling, you must implement the HTTP protocol manually. It's better for custom network apps rather than out-of-the-box web servers, which might prefer frameworks like net/http.

Question 6

How to implement a repeating timer with the event library?

Accepted Answer

Use NewTicker to create a repeating event, e.g., ev := event.NewTicker(base, callback, arg), and attach it with ev.Attach(time.Second) to trigger every interval, as detailed in the ticker section of the README.
