      • system

        @JvmOverloads() final static String system(String cmd, Long timeoutSeconds)

        Executes a system command and returns the output or error.

        This function reads stdout and stderr concurrently to avoid deadlock. If both streams are read sequentially, the process can block when its stderr buffer fills up while we're still reading stdout, causing a hang.

        Parameters:
        cmd - The command to execute
        timeoutSeconds - Maximum time to wait for the command to complete (0 = no timeout)
        Returns:

        The output of the command, or an error message if the command failed or timed out

      • system

        @JvmOverloads() final static String system(String cmd)

        cmd - The command to execute
        Returns:

        The output of the command, or an error message if the command failed or timed out

      • lineTempName

         final static String lineTempName(String solverName)

        Creates a temporary directory within a workspace for a solver.

      • removeDirectory

         final static Unit removeDirectory(Path dirPath)

        Recursively deletes a directory and its contents.
