C/C++ DocTest

A C/C++ DocTest that runs tests using clang-repl interaction in comments. Supports Linux (macOS is untested).

Prerequisites

• clang-repl-kernel version 0.1.8
• libclang must be installed and functioning properly

Usage

sample.cpp

#include "sample.h"
namespace test {
/**
>>> test::Fac fac;
>>> %<< fac.fac(7);
5040
*/
int Fac::fac(int n) {
    return (n > 1) ? n * fac(n - 1) : 1;
}
/**
>>> test::Fac fac;
>>> %<< fac.fac2(5);
120
*/
int Fac::fac2(int n) {
    return (n > 1) ? n * fac(n - 1) : 1;
}
}

sample.h

#pragma once
/**
>>> test::Fac fac;
>>> %<< fac.fac(5);
120
>>> %<< fac.fac2(5);
120
*/
namespace test {
class Fac {
public:
/**
>>> test::Fac fac;
>>> %<< fac.fac(5);
120
*/
    int fac(int n);
    int fac2(int n);
};
}
