I am not sure what exactly you are trying to achieve or what you are actually doing. Also what you know about the input - for example, do you know what the prompt is or whether each command starts with curl, or something else?
If I had to implement a method to capture a command to be executed, I would do it like this:
private Regex Prompt = new Regex("^.*@.*:.*[$#>] ?");
private void terminal_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
var s = terminal.Screen;
var top = s.CursorTop;
var lines = new StringBuilder();
for (int i = top; i >= 0; i--)
{
var line = s.GetRegionText(0, i, s.Columns, 1)[0];
var m = Prompt.Match(line);
if (m.Success)
{
lines.Insert(0, line.Substring(m.Length));
break;
}
else
{
lines.Insert(0, line);
}
}
MessageBox.Show(lines.ToString().Trim(), "Captured command");
}
}
The code above expects the prompt to be in the format user@machine:path$
It searches for the line containing the prompt.
It starts at the current cursor line (Screen.CursorTop) and goes one line up if the prompt was not detected.
This code was successfully tested with command echo Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris eget urna ut nibh laoreet ultrices. which spanned across three lines.
Please also note that if the user types very quickly, the last one or two characters of the command may not yet be displayed on the terminal screen when the ENTER is pressed. To ensure all sent/received data have been processed by the terminal before calling the GetRegionText() method, you should add terminal.Scripting.Process() method call at the beginning of the detection logic (just after the if (e.KeyCode == Keys.Enter) check). It can look like this:
terminal.UserInputEnabled = false;
terminal.SetDataProcessingMode(DataProcessingMode.None);
try
{
while (terminal.Scripting.Process(500) == TerminalState.DataReceived) ;
}
finally
{
terminal.UserInputEnabled = true;
terminal.SetDataProcessingMode(DataProcessingMode.Automatic);
}
If you want to achieve something else, or if you have a different scenario, please describe it in more detail. Also providing some of your existing code would be appreciated.
