Goose

Goose is a small utility library which supports inserting STL collection-like types to the output streams. It also provides stringification of such collections.

Supported platforms

Supported C++ standard versions are 17 and 20. Linux and Mac are tested on the CI. Support for Windows is not guaranteed.

Usage

1. Goose can be used as single header library from the release version.
2. Another way of using Goose is to add this repo as a submodule. Currently, only CMake is supported as a build system.

Examples

Using overloaded operator<< for STL collections

One-dimensional vector:

std::vector<int> vec{1, 2, 3, 4};
std::cout << vec << std::endl;

Output:

[1, 2, 3, 4]

Two-dimensional vector (I'm not saying you should use this example in production :D):

using Vec2 = std::vector<std::vector<int>>;
Vec2 vec2{{1, 2, 3, 4}, {-1, -2, -3, -4}, {42, -68}};
std::cout << vec2 << std::endl;

Output:

{[1, 2, 3, 4],
 [-1, -2, -3, -4],
 [42, -68]}

Using gos::to_string for STL collections

using HashMap = std::unordered_map<std::string, int>;
HashMap map{{"some", 42}, {"random", 600}, {"words", 68}};
auto stringified_map = gos::to_string(map);
std::printf("Stringified map: %s\n", stringified_map.c_str());

Possible output:

Stringified map: [[words, 68], [random, 600], [some, 42]]
