It is good to have customization of serve port

I'm running pyxtermjs on port 5002 and it works fine in this link
http://localhost:5002

I'm using nginx to proxy port 8083 to port 5002, to be able to access to terminal from port 8083
http://localhost:8083

But here the connection is blocked and it shows this
ERROR (_log_error_once:720) http://localhost:8083 is not an accepted origin. (further occurrences of this error will be logged with level INFO)

I guess it is blocking connections from other ports as a security feature. Is there any way to allow this ?

Hi guys,

thanks for this amazing tool,
I wanted to integrate pyxtermjs on an existing python script already using flask (to avoid to use a reverse proxy using 2 ports)
Is there a simple way for this integration?

Many thanks

pyxterm.js uses flask+flask-socketio on the backend. To get new output from the pty, it runs socketio.sleep() and checks for new output in an endless loop.

It would be better if it could use async+await to immediately forward the new output over a websocket. The new async web framework Bocadillo would be a good alternative to try since it now has websocket support bocadilloproject/bocadillo#75.

I am trying to save the user prompt to a log file but this program receives every key that is pressed by user without filtering any. Is there any way to save only the input when pressed enter?

Thank you for this awesome tool. Is there a straight-forward way to integrate the sound output of Terminal Applications running on pyxtermjs through the browser? Thank you again.

Maybe this issue can keep a long-term activity status without being closed for accepting more good use scenarios.

following install directions, pip install -r requirements, got error

Could not find a version that satisfies the requirement pkg-resources==0.0.0 (from -r requirements.txt (line 7)) (from versions: )
No matching distribution found for pkg-resources==0.0.0 (from -r requirements.txt (line 7))

Fixed by removing line pkg-resources==0.0.0 from requirements.txt

Tried this on windows 7 and it says no module named 'termios'.
Getting the same error while importing in seperate py file. Also cant install via pip when further researched it is found : no distribution available for windows

so for the time it is safe to say that this package is only linux supportive?

If not have authentication, it will make a great security risk.

The purpose of this issue is to address the ability to port over to another flask application that I have been building. Currently if pyxtermjs is run with the following command the application works just fine.

python3 app.py

However when run under flask with the command "flask run" the application looses the interactivity with the shell session.

I am wondering why this is and how someone can go through and add/take-away from this base example to include it in an already existing flask application.

Why terminal is not autosized by window size? What is the reason for this behavior?

Hello
I need to implement a web terminal base on flask and use the factory mode to start up the app.
My question is what time the pty.fork() function child_pid equal zero?

your code

(child_pid, fd) = pty.fork()
    if child_pid == 0:
        # this is the child process fork.
        # anything printed here will show up in the pty, including the output
        # of this subprocess
        subprocess.run(app.config["cmd"])
    else:
        # this is the parent process fork.
        # store child fd and pid
        app.config["fd"] = fd
        app.config["child_pid"] = child_pid
        set_winsize(fd, 50, 50)
        cmd = " ".join(shlex.quote(c) for c in app.config["cmd"])
        print("child pid is", child_pid)
        print(
            f"starting background task with command `{cmd}` to continously read "
            "and forward pty output to client"
        )
        socketio.start_background_task(target=read_and_forward_pty_output)
        print("task started")

In my application, I can't launch the subprocess.

I'm in a situation where I have to create child pty fork for each user session. I exactly followed your approach and it's working great but text delay (while on emitting the pty output) happens if more than 3 sessions got opened (in the background it created three child processes). Please help me to overcome this situation. Does making use of async func would help? or do we have to use any low level functions like os.wait() or os.waitpid() ?

Thanks for your great work now I am trying to learn and build something cool based on your project.

And now I am facing a problem that I can not solve myself after doing a lot researches...

Let's say the starting path is /User/Example/App

and then the command input sequence from web side is :

cd ..
cd ..

And now the current path should be at /User but how can I get this path using code ?

Any advice will be appreciated, thanks :)

I'd like a command-line argument that lets me specify a custom CSS file to use. For example, I might want to use some CSS that changes the way that the connected/disconnected looks, or I might want to specify a specific font for part of it.

Can a feature please be added to support adding custom CSS into pyxter.js?

Hi Chad,
We are using a similar xtermjs application using node js (node-pty) to host the terminal process and SignalR for communication with the web host. I’ve been looking at doing the same thing using python for about a year (!) until I came across pyxtermjs and was super existed.

I’m not a python guru by any means, but I got most of it working, but I got stuck on the initiation where I run into some issues which seems related to threading.
What would it take to get an hour of your time to see if you can point me in the right direction? I’m not looking for a free-bee. I’m happy to reimburse you since I’m really stuck right now.

You can reach me a mikael dot hakansson at axians dot com. or on twitter @wmmihaa

Cheers
Mikael
