spdlog(fmtlib)で std::vector を扱う.

More than 1 year has passed since last update.


spdlog(or fmtlib の fmt::print) で, std::vector の数値配列をロギングしたり(行列とか)したい.


spdlog で, fmtlib を有効にしているものとします.

fmtlib の join を使うのが楽でしょうか.


std::vector<float> values{0.0f, 0.2f, 0.3f};
fmt::print("values = [{}]", fmt::join(values, ", "));

// values = [0.0, 0.2, 0.3]

同様にして, std::array も扱うことができます.
