Embed Directive in Cilk

Here’s the translation of the Go code to Cilk, formatted in Markdown suitable for Hugo:

#include <cilk/cilk.h>
#include <iostream>
#include <string>
#include <fstream>
#include <vector>

// In Cilk, there's no direct equivalent to Go's embed directive.
// We'll simulate it by reading files at runtime.

std::string read_file(const std::string& filename) {
    std::ifstream file(filename);
    return std::string((std::istreambuf_iterator<char>(file)),
                        std::istreambuf_iterator<char>());
}

int main() {
    // Simulating the embedding of single_file.txt
    std::string fileString = read_file("folder/single_file.txt");
    std::vector<char> fileByte(fileString.begin(), fileString.end());

    // Print out the contents of single_file.txt
    std::cout << fileString;
    std::cout << std::string(fileByte.begin(), fileByte.end());

    // Simulating the embedding of multiple files
    std::string content1 = read_file("folder/file1.hash");
    std::cout << content1;

    std::string content2 = read_file("folder/file2.hash");
    std::cout << content2;

    return 0;
}

This Cilk code simulates the functionality of the original example. However, it’s important to note that Cilk doesn’t have a direct equivalent to the embed directive found in Go. Instead, we’ve implemented a simple file reading function to load the contents of files at runtime.

Here’s an explanation of the changes:

1. We include necessary headers for Cilk, I/O operations, and string manipulation.

2. We define a read_file function that reads the contents of a file into a string. This simulates the embedding functionality.

3. In the main function, we use read_file to load the contents of single_file.txt into both a string and a vector of bytes, mirroring the original Go code.

4. We print the contents of single_file.txt using both the string and byte vector representations.

5. We then simulate reading multiple files by calling read_file for file1.hash and file2.hash, and print their contents.

To run this example, you would need to compile it with a Cilk compiler and ensure that the folder structure and files exist as in the original example. The command might look something like this:

$ cilk++ -o embed_example embed_example.cpp
$ ./embed_example

Remember that this is a runtime simulation of the compile-time embedding in Go. In a real-world scenario, you might want to consider more efficient ways of handling file I/O in Cilk, especially for larger files or performance-critical applications.
