Header file.h

This header provides helper functions to read/write data from/to files easily.

Examples

The following code snippet reads a file and computes SHA-1 hash of the contents:

#include <clu/file.h>
#include <clu/assertion.h>

int main()
{
    std::vector<int> data{ 1, 2, 3, 4 };
    clu::write_all_bytes("data.bin", data);
    const auto read = clu::read_all_bytes<int>("data.bin"); // read as vector of ints
    const auto bytes = clu::read_all_bytes("data.bin"); // default behavior is to read as vector of bytes
    CLU_ASSERT(read == data);

    clu::write_all_text("data.txt", "Hello, world!");
    const std::string text = clu::read_all_text("data.txt");
    CLU_ASSERT(text == "Hello, world!");
}
