Linux ‘htop’ command can support mouse click

but xterm.dart can't suport

When using TerminalIsolate:

Future<TerminalIsolate> _ensureTerminalStarted() async {
    print("start");
    if (terminal == null) {
      terminal = TerminalIsolate(
        backend: FakeTerminalBackend(),
        maxLines: 10000,
        theme: widget.theme,
      );
    }

    if (!terminal!.isReady) {
      await terminal!.start(); // block here
    }
    print("end");
    return terminal!;
  }

the code will block on start().

When you add text to the terminal (Terminal.write), then scroll, you start in a weird position.

Press the up,down, left and right keys on the keyboard, will cause the automatic focus other widget.
ex.
press "Arrow Down" key, TerminalView's focus disable, the focus will appears on the button.

Great app, but web endorsement should probably removed from pub.dev

If I click space key inside terminal on chrome browser, nothing happens, no space inserted, not even even pops out.

Application such as vim cause crash because of they send binary message instead of UTF-8 char stream. This PR resolve the probleam.

TerminalStudio/dartssh#1

Just a quick question, is it possible to copy/paste text inside of the Terminalview? If yes what's the keyboard shortcut?
I tried the following combinations which didn't work on my Macbook:

• ctrl + v
• ctrl + shift + v
• command + v
• command + shift + v

none of them worked

The example is using a fake Terminal, and it works well.
but I don't know how to use this lib to connect to the Local Terminal.
Is there a way to do this?

As title suggests, Ctrl+C doesn't start a new line.

Affects 2.0.0 to 2.5.0-pre

Can we add an option for bright white in TerminalTheme?

It would be very interesting to be able to search for a term inside the terminal. In the search, each result would be selected in the terminal. And with the functions of searching next and previous.

Like this plugin for xterm.js: https://github.com/xtermjs/xterm-addon-search

frontend/terminal_view.dart

this api would trigger reflow and finally run into setScrollOffsetFromBottom, which refresh and make rebuild again. [rebuild in rebuild progress] is not allow so it cause crash in flutter. which happened in vim or tmux application.

I think it should be carefully use rebuild api in builder: )

Running as a macOS app, I'm getting the following error:

Input will slow down when there are too many characters in the terminal
System: windows10
TerminalSize: 1920*1080
example: vim、top...

There are some situations where the cursor movement is wrong.
I have recorded an example (using Tab to get command suggestions).

First try (works): entering "cmatr", then Tab (only one hit) => cmatrix is written ✔️
Second try (breaks): entering "cm", then Tab (3 hits) => Cursor is in the wrong line and writes "cm" over the result ❗

I would like to set the terminal font using GoogleFonts but in order to do this I would need to pass a TextStyle rather than a font name. Is there a reason why the TerminalStyle does not accept a TextStyle? I can contribute a PR if you would be open to the change and if there are no other blockers. Thank you

Platform: Android

Any Key that is not printable is not working... How should a terminal be used if we can't use things like backspace, Ctr-....

So i wrapped a RawKeyboardListener around the TerminalView and implemented some basic stuff based on the ASCII-Table:
https://github.com/flutter/flutter_web/blob/master/packages/flutter_web/lib/src/services/keyboard_maps.dart
http://www.physics.udel.edu/~watson/scen103/ascii.html

onKey: (event) {
  if (event.runtimeType.toString() == "RawKeyDownEvent") {
    RawKeyEventDataAndroid data = event.data as RawKeyEventDataAndroid;
    if (!_keyDownBuffer.contains(data.keyCode)) _keyDownBuffer.add(data.keyCode);
  }else if (event.runtimeType.toString() == "RawKeyUpEvent") {
    List<int> bytes;
    if (_keyDownBuffer.length == 1) {
      switch (_keyDownBuffer[0]) {
        case 19: bytes = [0x1b, 0x5b, 0x41]; break; // arrow up
        case 20: bytes = [0x1b, 0x5b, 0x42]; break; // arrow down
        case 21: bytes = [0x1b, 0x5b, 0x44]; break; // arrow left
        case 22: bytes = [0x1b, 0x5b, 0x43]; break; // arrow right
        case 61: bytes = [0x9]; break; // tab
        case 67: bytes = [0x8]; break; // backspace
      }
    } else if (_keyDownBuffer.length == 2) {
      switch (_keyDownBuffer[0]) {
        case 113: // Ctrl
          switch (_keyDownBuffer[1]) {
            case 29: bytes = [0x1]; break; // A (start of heading)
            case 30: bytes = [0x2]; break; // B (start of text)
            case 31: bytes = [0x3]; break; // C (end of text)
            case 32: bytes = [0x4]; break; // D (end of xmit)
            case 33: bytes = [0x5]; break; // E (enquiry)
            case 34: bytes = [0x6]; break; // F (acknowledge)
            case 35: bytes = [0x7]; break; // G (bell)

            case 38: bytes = [0x10]; break; // J (line feed)
            case 39: bytes = [0x11]; break; // K (vertical tab)
            case 40: bytes = [0x12]; break; // L (form feed)
            case 41: bytes = [0x13]; break; // M (carriage feed)
            case 42: bytes = [0x14]; break; // N (shift out)

            case 51: bytes = [0x23]; break; // W (end of xmit block)
            case 52: bytes = [0x18]; break; // X (cancel)
            case 53: bytes = [0x19]; break; // Y (end of medium)
            case 54: bytes = [0x1a]; break; // Z (substitute)
          }
          break;
      }
    }
    // send to serial
    _keyDownBuffer.clear();
    if (bytes != null && bytes.length != 0) globals.platform.invokeMethod("sendBytes", Uint8List.fromList(bytes));
  }
}

Could we get a listener like the onInput were we can just send the bytes with non printable stuff to the backend? This solution is really bad since also flutter reacts to some stuff and the keyboard disappears or the focus get's lost...

Hello, I am implementing a console for a very specific purpose.

I have 2 questions.

Can I disable the cursor (and entire input system) so that I can implement my own input?
or
Is there an easy way to retrieve text on submit instead of every character inputted?

There were some dependency problem and break change in desktop generation.

In addition, I check this file on Github, and I see that this is not the same version.

Do you have a solution ?

After I upgrade flutter SDK to 3.0, I can't run my app.
Could you provide a new version to add compatibility with flutter 3.0?

Use vim to open a text file. First, move cursor to the file bottom, then, move cursor up. When cursor hit the top of screen, vim dose not scroll up properly. Only first line content changed, other lines remain unchanged.

Hi,

in your example you are using an old version of dartssh2. If i try to use the latest version of dartssh2, it stucks on connecting unfortunately and the xterm doesn't refresh. Is possibile to use the latest version of xterm with the latest version of dartssh2? In particular, i mean the SSH implementation. The SSH implementation is totally different on dartssh2 page. On your example is reported totally differently

OS: Linux (Manjaro)
Flutter version: 1.26.0-1.0.pre
Dart version: 2.10.5
xterm version: 1.1.1+1

I created a brand new app and reproduced the exact code that is in the example section. The app ran but every time I try to delete a character with the backspace key, it adds an empty space char.

open a text file on linux server, hen a line of text file has thousands of characters, exception occurred:

hi, this is really awesome plugin! but i cannot write anything using my phones keyboard. thanks.

I have git-cloned the repository of xterm and set the host, username and password parameters of /example/lib/ssh.dart.

The example/lib/ssh.dart runs smoothly on Android emulator (API 30) (except for the physical BACKSPACE key of my bluetooth keyboard which does not work).

But the very same example/lib/ssh.dart does not run on Chrome (web-javascript). It is stuck to "connecting ssh://my.host.com:my_port..."

It is said in the xterm package description at pub.dev: "(...) with support for mobile and desktop platforms." Perhaps web platform is not supported yet?

When I try to insert a letter with accents it looks as if I had pressed the button 2 times.

While this generally occurs with the command cd ~, it has happened on other commands.

Affects 2.0.0 to 2.5.0-pre

I know that this is not the ideal place to ask this question, but in the repository of the lib "dartssh" there is no way to create issues, so is it possible to upload/download/move files via SFTP with your dartssh lib?

https://github.com/TerminalStudio/dartssh

This package is fantastic! I love it!

I was wondering if it was possible to have some more detailed documentation? Most of the API is pretty self-explanatory but some of it I wasn't sure about. For example, Terminal.newLineMode is a bool but it's not clear what true or false mean. Same with Terminal.originMode.

i clone your project ,and run local.dart with command 'flutter run -d macos',and error like that:

The process has forked and you cannot use this CoreFoundation functionality safely. You MUST exec().
Break on THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC() to debug.

In the xterm example, the SSH connection is not available in MacOS, but IOS can. How to solve this problem

The problem is here:

Handling this kind of thing is unfortunately a bit more complicated. The C++ code ends up thinking it needs to keep updating you, and it sends an update which causes you to also send an update, and it goes back and forth in a loop. The expectation is that if you send an update and get a new message, you won't send an update again if the values have not changed. You can see how the framework handles this here: https://github.com/flutter/flutter/blob/f0c9710493d3431a1983967dc26fad2a8513b94e/packages/flutter/lib/src/widgets/editable_text.dart#L1958-L1966

I'm surprised this isn't causing bigger problems on other platforms, but maybe it is. At any rate, the problem on macos is very noticable if you add a print to the onInput in the example - it will print indefinitely as soon as interaction starts with the application.

Text spacing is a little off on chrome. I am running

  xterm: ^2.4.0-pre

Between the t and e in text , there seems to be a lot more space. I am just using the default TextView

            Expanded(
                child: message.when(
                    loading: () => const CircularProgressIndicator(),
                    error: (err, stack) => Text('Error: $err'),
                    data: (message) {
                      terminal.write(message);
                      return TerminalView(
                        terminal: terminal,
                      );
                      // style: TerminalStyle(fontFamily: ["Cascadia Code"]));
                    })),

Any feedback or workaround is appreciated.

I am trying to install the example, but when it tries to get the dependencies it tells me this:
Because no versions of dartssh match >1.0.3+3 <2.0.0 and dartssh 1.0.3+3 depends on convert ^2.1.1, dartssh ^1.0.3+3 requires convert ^2.1.1.
And because every version of xterm from path depends on convert ^3.0.0, dartssh ^1.0.3+3 is incompatible with xterm from path.
So, because example depends on both xterm from path and dartssh ^1.0.3+3, version solving failed.
Running "flutter pub get" in example...
pub get failed (1; So, because example depends on both xterm from path and
dartssh ^1.0.3+3, version solving failed.)

It throws RangeError (byteOffset): Index out of range: index must not be negative: -36 when I call the selectedText of Terminal instance.

Step:

1. Select a line text in TerminalView widget by mouse manually. (Note that it must be a whole line of text starting at the beginning of the line, not part of a line.)
2. Call the terminal.selectedText getter.

flutter version: 2.10.0
OS version: macOS 12.1
app build platform: desktop (macOS)
xterm plugin version: 2.6.0

I'm developing an mobile ssh application with xterm.dart. Is there any plan to support features, such as

1. search
2. open external uri
   and so on?

I have worked in an electron application, witch use xterm.js to provide terminal feature, and our application suffered from the pool performance of web.
It's unexpectedly good performance that xterm.dart has. I'm very interested this project. : )

As far as I can see xterm.dart currently doesn't have the reflow logic ported from xterm.js.
Is this planned?
I had a brief look at it and it currently can't be ported directly because the way the buffer works is slightly different to xterm.js (no CircularList for example).
I could take over that task if you like but I think we would have to discuss the best approach here.

Hi, I just wrote a flutter page with xterm.dart based on the example : https://github.com/TerminalStudio/xterm.dart/blob/master/example/lib/main.dart

Everything is ok when running as a standalone flutter app.

But it can`t receive input from the soft keyboard when added as flutter module to an existing Android project.

Source code of the demo is here: https://github.com/luxi78/xterm.dart_in_module

Hope someone can find out what the problem is, Thanks!

There was the build error.
