This release contains 2 new utility classes I needed for MQTT.fx‘s script editing function Desktop and Shell.

By now I used to open a script for editing with the system default editor via java.awt.Desktop. So far this works well on my Mac but there were issues on Windows and Linux. To get rid of these issues I create my own Desktop class to open the script directly with the system shell:

Desktop

public class Desktop {

    public static boolean edit(String fileToEdit) {
        return openWithSystem(fileToEdit);
    }

    private static boolean openWithSystem(String fileToOpen) {
        if (OS.isLinux()) {
            if (Shell.canOpen("gnome-open", fileToOpen)) {
                return true;
            } else if (Shell.canOpen("kde-open", fileToOpen)) {
                return true;
            } else if (Shell.canOpen("xdg-open", fileToOpen)) {
                return true;
            }
        } else if (OS.isWindows()) {
            if (Shell.canOpen("explorer", fileToOpen)) {
                return true;
            }
        } else if (OS.isMac()) {
            if (Shell.canOpen("open", fileToOpen)) {
                return true;
            }
        }
        return false;
    }
}

Shell

public class Shell {

    public static boolean canOpen(String... command) {
        try {
            ProcessBuilder builder = new ProcessBuilder(command);
            Process process = builder.directory(new File(System.getProperty("user.home"))).start();
            if (process == null) {
                return false;
            }
            try {
                process.exitValue();
                // if this does not throw an IllegalThreadStateException the process is not running/has exited immediately
                return false;
            } catch (IllegalThreadStateException e) {
                // the process seems to be in a running state
                return true;
            }
        } catch (IOException ex) {
            return false;
        }
    }

    public static List<String> prepareOpenFileLine(String command, String fileToOpen) {
        List<String> commandList = new ArrayList<>();
        for (String s : command.split(" ")) {
            commandList.add(s.trim());
        }
        commandList.add(fileToOpen);
        return commandList;
    }

    public static Optional<Process> execute(List<String> command) throws IOException {
        return execute(new File(System.getProperty("user.home")), command);
    }

    public static Optional<Process> execute(File directory, String... command) throws IOException {
        return execute(directory, Arrays.asList(command));
    }

    public static Optional<Process> execute(String... command) throws IOException {
        return Shell.execute(new File(System.getProperty("user.home")), command);
    }

    public static Optional<Process> execute(File directory, List<String> command) throws IOException {
        ProcessBuilder builder = new ProcessBuilder(command);
        Process process = builder.directory(directory).start();
        return Optional.of(process);
    }
}
