LesleyLai / locate_asset_path.cpp
Created November 11, 2022 09:19
Little C++ utility to searching upward until finding a "assets" subdirectory. Useful during development when I don't want to copy the assets to build directory every time.
auto locate_asset_path(const std::filesystem::path& current_path)
-> std::optional<std::filesystem::path>
{
namespace fs = std::filesystem;
std::optional<fs::path> result = std::nullopt;
for (auto path = current_path; path != current_path.root_path();
path = path.parent_path()) {
const auto assets_path = path / "assets";
if (exists(assets_path) && is_directory(assets_path)) {
