Embed Directive in Scilab

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

Our first example demonstrates how to include external files in a Scilab script. Scilab doesn’t have a built-in embed directive like some other languages, but we can achieve similar functionality using file I/O operations.

// Import necessary modules
// In Scilab, there's no need to import modules for basic file operations

// Read the contents of a single file into a string
function fileString = readFileToString(filename)
    fd = mopen(filename, 'r');
    fileString = mgetl(fd, -1);
    mclose(fd);
endfunction

// Read the contents of a single file into a matrix of bytes
function fileByte = readFileToBytes(filename)
    fd = mopen(filename, 'rb');
    fileByte = mget(fd, -1, 'uc');
    mclose(fd);
endfunction

// Main function
function main()
    // Print out the contents of 'single_file.txt'
    fileString = readFileToString('folder/single_file.txt');
    disp(fileString);
    
    fileByte = readFileToBytes('folder/single_file.txt');
    disp(ascii(fileByte));

    // Retrieve some files from the folder
    content1 = readFileToString('folder/file1.hash');
    disp(content1);

    content2 = readFileToString('folder/file2.hash');
    disp(content2);
endfunction

// Execute the main function
main()

To run this example, you’ll need to create the necessary files and folders first. Here are the commands to set up the environment:

$ mkdir -p folder
$ echo "hello scilab" > folder/single_file.txt
$ echo "123" > folder/file1.hash
$ echo "456" > folder/file2.hash

Then, you can run the Scilab script:

$ scilab -f embed_example.sce

The output should be:

hello scilab
hello scilab
123
456

This example demonstrates how to read files in Scilab, both as strings and as byte arrays. While Scilab doesn’t have an embed directive, we can achieve similar functionality by reading files at runtime.

The readFileToString function reads a file and returns its contents as a string, while readFileToBytes reads a file and returns its contents as a matrix of unsigned chars (bytes).

In the main function, we read and display the contents of the files we created. This approach allows us to include external files in our Scilab scripts, albeit at runtime rather than compile-time.
