termios.error: (25, 'Inappropriate ioctl for device')

[chinmaya-n]

Greetings!

When I try to run the program below, It gives Error as in the title. Image is here: http://imgur.com/9no96dh

import readchar

while True:
    print "Press 'A' to Start the recording"
    print "      'Z' to Stop the recording"
    print "      'Enter' to quit the program..."

    # Read a key
    key = readchar.readkey()
    if(key == 'A'):
        print "Started Recording..."
    elif(key == 'Z'):
        print "Stopped Recording..."
    elif(key == '\r'):
        print "Exiting..."
        break
    else:
        print "Please Use only allowed keys: A, Z, Enter!" 

I tried to do just run readchar.readkey() in python console, It worked fine there. But when I tried to do it as above, this error occurred. Any help will be greatly appreciated.

Note: I'm on Ubuntu Gnome x86_64. Kernel: 3.19.* v. Using Python 2.7.

Thanks & Regards, inblueswithu

which version are you using? Please, use version 0.7. It is the only one I assure that works, because I tried to change my mind in order to support other things... And it didn't work.

https://pypi.python.org/pypi/readchar

Thank you!

I installed using pip. http://imgur.com/LswwHag. You can see that my version is 0.7. readchar-0.7.dist-info

[techgnosis]

I'm having the same bug with readchar 0.7

[chinmaya-n]

@techgnosis Can you please try to run my program in your PC and check if its the same error for you?

[magmax]

Well... first of all, use readchar.keys.ENTER instead of \r. But this is not going to fix the problem.

I ran it in my machine (Python 2.7.10, virtualenv 13.1.2-2, readchar 0.7, ArchLinux, Awesome wm) with no problem.

How could I reproduce it?

[magmax]

Ok. I have it.

Running it with thunar, it returns the error::

termios.error: (25, 'Inappropriate ioctl for device')

this is because I'm trying to get the terminal settings but it is not running in a terminal environment.

I'm not sure about a good fix for this, but forcing it to be run in a terminal. I will investigate further more.

[techgnosis]

That makes sense. I was running it in PyCharm. I didn't try to run it in the terminal..

@magmax You are right. I now ran the program in a terminal and it worked great! I have been trying to run it from WingIDE.

[techgnosis]

Worked for me too. Thanks guys

So nothing more is required and this issue can be closed.

By the way... Maybe this other library can help you: https://github.com/magmax/python-inquirer

I wrote python-readchar just to create it. Here you are more examples: http://python-inquirer.readthedocs.org/en/latest/examples.html

[chinmaya-n]

It seems my requirement is out of scope for this library (as you are concentrating with in terminal only, but not from any other IDEs or non terminal executions). I think you can close it.

Thank you all!

[magmax]

I'm afraid yes. Maybe you can use pty or https://github.com/pexpect/ptyprocess in order to make it work in a non-terminal environment.

Thank you anyways.

[chinmaya-n]

ThankYou. ptyprocess is interesting.

This would be useful if it works in IDE, trying to debug some code using the IDE's debugger but this error won't let me do it.

Hi, guys, Do you solve the problem? I got the same exception when I run the following code: `

code line in script

width = os.get_terminal_size().columns

run

../bin/normalizer.py input.tsv out.tsv 1> log 2> error

For future self and similar - might be also an issue if you pass sth "defintiely not being tty", i.e. I saw it when we used local file by accident.

Partly resolution for pycharm https://intellij-support.jetbrains.com/hc/en-us/community/posts/360003383619/comments/6589796593042 (but readkey on macos can't read shift+tab and etc)
