Question 1

How do I install cl-async with libuv on Linux?

Accepted Answer

First, install libuv v1.x via your package manager (e.g., `apt-get install libuv1-dev`), then load cl-async via Quicklisp. If not in Quicklisp, clone it into local-projects as per the README instructions.

Question 2

Is cl-async better than Bordeaux-threads for async tasks?

Accepted Answer

cl-async is for non-blocking I/O using libuv, ideal for network operations, while Bordeaux-threads handles multi-threading. Use cl-async for event-driven I/O and Bordeaux-threads for CPU-bound concurrency; they can complement each other.

Question 3

Can I build a web server with cl-async?

Accepted Answer

Yes, but cl-async provides low-level TCP/SSL drivers, so you'll need to implement HTTP protocol handling yourself or use a higher-level library like Hunchentoot with async patches, as cl-async focuses on foundational async I/O.

Question 4

How does error handling work in cl-async?

Accepted Answer

Errors are managed through structured event callbacks, where specific error handlers can be defined for operations like TCP or DNS, as detailed in the event handling documentation on the project website.

Question 5

What are the performance benchmarks for cl-async?

Accepted Answer

The README links to benchmarks showing cl-async's efficiency with libuv, comparable to Node.js in I/O throughput, but actual performance depends on system setup and use case specifics.

Question 6

Is cl-async production-ready for Common Lisp apps?

Accepted Answer

It has a comprehensive test suite and uses stable libuv, making it suitable for production, but ensure libuv compatibility and test thoroughly due to its lower-level nature and dependency on external C libraries.
