  • Specify private SSH-key to use when executing shell command with or without Ruby?

    - by Christoffer
    A rather unusual situation perhaps, but I want to specify a private SSH-key to use when executing a shell (git) command from the local computer. Basically like this: git clone [email protected]:TheUser/TheProject.git -key "/home/christoffer/ssh_keys/theuser" Or even better (in Ruby): with_key("/home/christoffer/ssh_keys/theuser") do sh("git clone [email protected]:TheUser/TheProject.git") end I have seen examples of connecting to a remote server with Net::SSH that uses a specified private key, but this is a local command. Is it possible? Thanks

  • Specifying column names from a list in the data.frame command.

    - by MW Frost
    I have a list called cols with column names in it: cols <- c('Column1','Column2','Column3') I'd like to reproduce this command, but with a call to the list: data.frame(Column1=rnorm(10)) Here's what happens when I try it: > data.frame(cols[1]=rnorm(10)) Error: unexpected '=' in "data.frame(I(cols[1])=" The same thing happens if I wrap cols[1] in I() or eval(). How can I feed that item from the vector into the data.frame() command?

  • How to use command bindings in user controls in wpf?

    - by Sam
    In MainWindow the commandbinding works fine. In UserControl1 it doesnt work. Note the datacontext is set correctly as is evidenced by the content of the button which is the result of a binding. I am not trying to bind the command in the usercontrol to a command in mainwindow or any other such trickery. I am just trying to replicate what I did in MainWindow in UserControl1. // MainWindow xaml <StackPanel> <Button Content="Click Here" Command="{Binding ClickHereCommand}" Height="25" Width="90"></Button> <local:UserControl1></local:UserControl1> </StackPanel> // MainWindow public partial class MainWindow : Window { public static RoutedCommand ClickHereCommand { get; set; } public MainWindow() { InitializeComponent(); this.DataContext = this; ClickHereCommand = new RoutedCommand(); CommandBindings.Add(new CommandBinding(ClickHereCommand, ClickHereExecuted)); } public void ClickHereExecuted(object sender, ExecutedRoutedEventArgs e) { System.Windows.MessageBox.Show("hello"); } } // UserControl1 xaml <UserControl x:Class="CommandBindingTest.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300" x:Name="root"> <Grid DataContext="{Binding ElementName=root}" > <Button Content="{Binding ButtonContent}" Command="{Binding ClickHereCommand}" Height="25" Width="90"></Button> </Grid> </UserControl> // UserControl1 public partial class UserControl1 : UserControl, INotifyPropertyChanged { private string _ButtonContent; public string ButtonContent { get { return _ButtonContent; } set { if (_ButtonContent != value) { _ButtonContent = value; OnPropertyChanged("ButtonContent"); } } } public static RoutedCommand ClickHereCommand { get; set; } public UserControl1() { InitializeComponent(); ClickHereCommand = new RoutedCommand(); CommandBindings.Add(new CommandBinding(ClickHereCommand, ClickHereExecuted)); ButtonContent = "Click Here"; } public void ClickHereExecuted(object sender, ExecutedRoutedEventArgs e) { System.Windows.MessageBox.Show("hello from UserControl1"); } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; public void OnPropertyChanged(string name) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(name)); } } #endregion }

    - by lallous
    Hello I want to attach to a running process using 'ddd', what I manually do is: # ps -ax | grep PROCESS_NAME Then I get a list and the pid, then I type: # ddd PROCESS_NAME THE_PID Is there is a way to type just one command directly? Remark: When I type ps -ax | grep PROCESS_NAME <- grep will match both the process and grep command line itself.

  • Problem creating calculations 'engine' in two class java calculator

    - by tokee
    i have hit a brick wall whilst attempting to create a two class java calculator but have been unsuccessful so far in getting it working. i have the code for an interface which works and displays ok but creating a seperate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which works with the interface class and allows input when from single button i.e. if one is pressed on the calc then 1 displays onscreen. please note i'm not asking someone to do the whole thing for me as i want to learn and i'm confident i can do the rest including addition subtraction etc. once i get over the obstacle of getting the two classes to communicate. any and all assistance would be very much appreciated. Please see the calcInterface class code below - import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.*; /** *A Class that operates as the framework for a calculator. *No calculations are performed in this section */ public class CalcFrame implements ActionListener { private CalcEngine calc; private JFrame frame; private JTextField display; private JLabel status; /** * Constructor for objects of class GridLayoutExample */ public CalcFrame() { makeFrame(); //calc = engine; } /** * This allows you to quit the calculator. */ // Alows the class to quit. private void quit() { System.exit(0); } // Calls the dialog frame with the information about the project. private void showAbout() { JOptionPane.showMessageDialog(frame, "Group Project", "About Calculator Group Project", JOptionPane.INFORMATION_MESSAGE); } private void makeFrame() { frame = new JFrame("Group Project Calculator"); makeMenuBar(frame); JPanel contentPane = (JPanel)frame.getContentPane(); contentPane.setLayout(new BorderLayout(8, 8)); contentPane.setBorder(new EmptyBorder( 10, 10, 10, 10)); /** * Insert a text field */ display = new JTextField(); contentPane.add(display, BorderLayout.NORTH); //Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(4, 4)); JPanel buttonPanel = new JPanel(new GridLayout(4, 4)); contentPane.add(new JButton("1")); contentPane.add(new JButton("2")); contentPane.add(new JButton("3")); contentPane.add(new JButton("4")); contentPane.add(new JButton("5")); contentPane.add(new JButton("6")); contentPane.add(new JButton("7")); contentPane.add(new JButton("8")); contentPane.add(new JButton("9")); contentPane.add(new JButton("0")); contentPane.add(new JButton("+")); contentPane.add(new JButton("-")); contentPane.add(new JButton("/")); contentPane.add(new JButton("*")); contentPane.add(new JButton("=")); contentPane.add(new JButton("C")); contentPane.add(buttonPanel, BorderLayout.CENTER); //status = new JLabel(calc.getAuthor()); //contentPane.add(status, BorderLayout.SOUTH); frame.pack(); frame.setVisible(true); } /** * Create the main frame's menu bar. * The frame that the menu bar should be added to. */ private void makeMenuBar(JFrame frame) { final int SHORTCUT_MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask(); JMenuBar menubar = new JMenuBar(); frame.setJMenuBar(menubar); JMenu menu; JMenuItem item; // create the File menu menu = new JMenu("File"); menubar.add(menu); // create the Quit menu with a shortcut "Q" key. item = new JMenuItem("Quit"); item.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, SHORTCUT_MASK)); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { quit(); } }); menu.add(item); // Adds an about menu. menu = new JMenu("About"); menubar.add(menu); // Displays item = new JMenuItem("Calculator Project"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { showAbout(); } }); menu.add(item); } /** * An interface action has been performed. * Find out what it was and handle it. * @param event The event that has occured. */ public void actionPerformed(ActionEvent event) { String command = event.getActionCommand(); if(command.equals("0") || command.equals("1") || command.equals("2") || command.equals("3") || command.equals("4") || command.equals("5") || command.equals("6") || command.equals("7") || command.equals("8") || command.equals("9")) { int number = Integer.parseInt(command); calc.numberPressed(number); } else if(command.equals("+")) { calc.plus(); } else if(command.equals("-")) { calc.minus(); } else if(command.equals("=")) { calc.equals(); } else if(command.equals("C")) { calc.clear(); } else if(command.equals("?")) { } // else unknown command. redisplay(); } /** * Update the interface display to show the current value of the * calculator. */ private void redisplay() { display.setText("" + calc.getDisplayValue()); } /** * Toggle the info display in the calculator's status area between the * author and version information. */ }

  • MVC Pass textbox to controller if not in a form tag

    - by user1679820
    I am working on and Microsoft MVC3 project and cannot pass a parameter which has been edited to the controller. It will only pass back the original set parameter For example: @Ajax.ActionLink("share file", InviteController.Actions.Result, InviteController.Name, new { message = Model.Message }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "popup", OnSuccess = "$('#popup').dialog('open')" }, new { id = "popup-button" }) <label>Personal Message <span class="optional-message">(optional)</span></label> @Html.TextAreaFor(x => x.Message) </div> This will pass the to the following controller but the 'message' parameter has the original message and not the updated message: public ActionResult Result(FormCollection coll, string message) { I'd love if someone could give me some advice. Many Thanks

  • PHP exec problem with s3-put

    - by schneck
    Hi there, I use the s3-bash-project to upload data to an S3-Bucket. My command looks like this: /mypath/s3_bash/s3-put -v -k '123456789' -s '/mypath/secret' -T '/mypath/upload/myuploadfile' '/my.bucket/mykeyname' I can run the command from the command line (Mac OS X), and it works well. Now I want to execute it from a PHP-Script: exec($command, $output); but in output, the "s3-put"-command only returns the command's help text. I log the command, and it works if I c&p it from the log the the command line, so there not a problem. It seems that PHP does not pass all the parameters to the command line, although I run escapeshellarg() over all the parameters. I'm using a local XAMPP-Test environment, safe_mode is off. Any ideas?
