Temporary Files And Directories in Scilab

Temporary files and directories are useful when we need to create data that isn’t needed after the program exits. They don’t pollute the file system over time.

function check(e)
    if e <> [] then
        error(e);
    end
endfunction

// The easiest way to create a temporary file in Scilab is by
// using the 'tempname' function. It returns a unique file name
// in the system's temporary directory.
f_name = tempname();
disp("Temp file name: " + f_name);

// We can write some data to the file.
fd = mopen(f_name, 'wb');
mput(int8([1, 2, 3, 4]), 'c', fd);
mclose(fd);

// Clean up the file after we're done.
deletefile(f_name);

// If we intend to create many temporary files, we may
// prefer to create a temporary directory.
// In Scilab, we can use the 'mkdir' function to create a directory
// and 'tempname' to generate a unique name for it.
dname = tempname();
[status, msg] = mkdir(dname);
check(msg);
disp("Temp dir name: " + dname);

// Now we can synthesize temporary file names by
// prefixing them with our temporary directory.
fname = fullpath(dname + filesep() + "file1");
fd = mopen(fname, 'wb');
mput(int8([1, 2]), 'c', fd);
mclose(fd);

// Clean up the directory and its contents
rmdir(dname, 's');

To run the script, save it as temporary_files_and_directories.sce and execute it in Scilab:

--> exec('temporary_files_and_directories.sce', -1)
Temp file name: /tmp/SCI_TMP_1234567890_123
Temp dir name: /tmp/SCI_TMP_0987654321_321

Note that the actual temporary file and directory names will be different each time you run the script.

In this Scilab script:

We use tempname() to generate unique temporary file names.
File operations are performed using mopen(), mput(), and mclose().
Directory creation is done with mkdir().
File and directory cleanup is handled by deletefile() and rmdir() respectively.
Error checking is done through a custom check() function.

Scilab doesn’t have built-in functions specifically for temporary files and directories like Go does, so we use a combination of temporary name generation and standard file/directory operations to achieve similar functionality.
