Signals in Scilab

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

Our example demonstrates how to handle signals in Scilab. While Scilab doesn’t have a direct equivalent to Go’s signal handling, we can use the atexit function to perform cleanup operations when the program is terminated.

function cleanup()
    disp("Cleaning up...")
    disp("exiting")
endfunction

function main()
    atexit(cleanup);
    
    disp("Program is running. Press Ctrl+C to terminate.")
    
    // Simulate a long-running process
    while %T
        sleep(1000);
    end
endfunction

main()

In this Scilab program:

1. We define a cleanup function that will be called when the program exits. This is similar to the signal handling in the original example.

2. In the main function, we register the cleanup function using atexit. This ensures that our cleanup code will be executed when the program terminates.

3. We then print a message indicating that the program is running and how to terminate it.

4. The while %T loop simulates a long-running process. In Scilab, %T represents true, so this is an infinite loop.

5. The sleep(1000) function causes the program to pause for 1 second in each iteration of the loop.

To run this program:

1. Save the code in a file, for example, signal_handling.sce.
2. Open Scilab and execute the script by typing exec('signal_handling.sce') in the Scilab console.
3. To terminate the program, press Ctrl+C in the Scilab console.

When you run this program, it will display:

Program is running. Press Ctrl+C to terminate.

And when you press Ctrl+C to terminate, it will display:

Cleaning up...
exiting

This example demonstrates a way to perform cleanup operations when a Scilab program is terminated, which is conceptually similar to signal handling in other languages. However, it’s important to note that Scilab’s signal handling capabilities are more limited compared to languages like C or Go.
