Abstract

Ne.app OCL provides free header-only C++ libraries for usage in C++ software development.

Modules include, a core library containing algorithms and containers for C++20 or later.

These libraries were built on top of the Boost C++ libraries and C++ SL.

Using OCL

This is taken from the FIX module, and will be used here as an example of usage of the OCL.

int main(int argc, char** argv)
{
	ocl::fix::visitor	   basic_visitor;
	ocl::fix::range_buffer fix = basic_visitor.visit(default_fix);

	ocl::io::enable_stdio_sync(false);

	ocl::io::print(":key=35\n");
	ocl::io::print(":value=", fix["35"], "\n");
}

The OCL are mostly headers only (except OCL.FIX as of 2026), so no compilation step is needed. And is C++17 or later.
