Question 1

How does sonic-cpp compare to simdjson?

Accepted Answer

Sonic-cpp and simdjson both use SIMD for speed, but sonic-cpp focuses more on C++11 compatibility and offers ParseOnDemand features, while simdjson might have broader platform support. Benchmarks in the README show sonic-cpp often outperforms in parsing and serialization on x86/Linux.

Question 2

How to integrate sonic-cpp into a CMake project?

Accepted Answer

Add the include directory with `-I/path/to/sonic/include/` in your compiler flags and ensure you're using GCC or LLVM on Linux with AVX2 support. The README provides example commands for building with CMake or Bazel, but note the specific hardware requirements.

Question 3

Is sonic-cpp compatible with Windows or Visual Studio?

Accepted Answer

No, the README explicitly states it does not support the MSVC compiler, limiting it to Linux environments with GCC or LLVM. For Windows, you'd need alternative JSON libraries or workarounds like WSL.

Question 4

Does sonic-cpp support streaming JSON parsing?

Accepted Answer

The README doesn't mention streaming capabilities; it focuses on in-memory parsing and serialization. For large files, you might need to handle chunking manually, as it's optimized for speed over incremental processing.

Question 5

What are the build requirements for sonic-cpp?

Accepted Answer

You need C++11 or above, an x86 platform with AVX2, GCC or LLVM compiler, and Linux OS. Compilation requires flags like `-march=haswell` for optimal performance, as shown in the usage examples.

Question 6

Can sonic-cpp validate JSON schema?

Accepted Answer

No, schema validation is not listed as a feature in the README or RoadMap. It's designed for fast parsing and manipulation, so you'd need to implement validation separately if required.
