Doc request: how to retrieve / print logs?

[rebcabin]

It's not clear how to access the buffers created by INFO and other logging mechanisms. Please see this stackoverflow question: http://bit.ly/1mJUoS0.

The following is a tiny MVP of something that does not work; about as far as I could get reading the source. I stalled at line 1559, where the code refers to scopedMessage, and I could not find a definition of that anywhere ... seems some deeper magic is happening.

#include <stdio.h>
#include <iostream>

#define CATCH_CONFIG_RUNNER
#include "catch.hpp"
using namespace std;

struct some_struct
{
    uint64_t timestamp;
    double lat;
    double lon;
    float alt;
};

TEST_CASE ("sizes", "[metadata]" ) {
    INFO ( "The number is " << 42 );
    REQUIRE (sizeof(some_struct) == 32);
}

int
main (int argc, char ** const argv) {
    int result = Catch::Session().run( argc, argv );
    // cout << Catch::MessageBuilder::m_stream;
    return result;
}

The INFO information is reported on failure (and with option --success), not on success (Catch streaming macros).

prompt>g++ -ICatch/single_include -o info.exe info.cpp & info.exe -r compact
info.cpp:18: failed: sizeof(some_struct) == 33 for: 32 == 33 with 1 message: 'The number is 42'
Failed 1 test case, failed 1 assertion.

cheers,
Martin

Ok, thanks for the clarification!
