Hi!

I'm using pretty-traceback as part of my application logging. App is deployed inside of a docker container which means app's process is not running in TTY.

When my loggers call formatException from:

class LoggingFormatterMixin(object):

    def formatException(self, ei):
        _, exc_value, traceback = ei
        return exc_to_traceback_str(exc_value, traceback, color=True)

I get "stty: standard input: Not a tty" message. This is because of following call chain:

exc_to_traceback_str() 
    --> _get_terminal_width() 
        --> os.get_terminal_size()

Current workaround for me is adding environment variable COLUMNS. It effectively prevents call to os.get_terminal_size.

This is fine, but is not perfect 😊 .

I would like to avoid adding COLUMNS env variable and would like to instead do this through code. Something like this would work for me, but any other solution that let's me somehow avoid call to os.get_terminal_size() is also fine:

- def exc_to_traceback_str(exc_value, traceback, color=False):
+ def exc_to_traceback_str(exc_value, traceback, color=False, columns=None):

• when columns is not None, use that, ignore os.environ["COLUMNS"] and don't call os.get_terminal_size()
• when columns is None keep current behavior

In a Linux environment, pretty-traceback is fantastic, except that for me it isn't issuing a final linefeed, leaving my prompt appended to the end of the final line of output.

A quick peek at the code suggests to me that this is to be expected, owing to use of sys.stderr.write() in hook.py, though I'm unclear if this behavior is intentional or not.

Assuming it isn't intentional, and hoping that the linefeed is also desirable and appropriate under Windows, I added + '\n' within hook.py thusly to get it working as I'd expect on my system:

def init_excepthook(color):
    def excepthook(exc_type, exc_value, traceback):
        tb_str = formatting.exc_to_traceback_str(exc_value, traceback, color) + '\n'

Executing python file as python script.py works fine. But if I try to do python ./script.py it gives the following error

Error in sys.excepthook:
Traceback (most recent call last):
  File "C:\Users\M1\anaconda3\envs\myenv\lib\site-packages\pretty_traceback\hook.py", line 23, in excepthook

  File "C:\Users\M1\anaconda3\envs\myenv\lib\site-packages\pretty_traceback\formatting.py", line 135, in _iter_entry_rows
    assert module.endswith(_module)

Tried to see pretty-tracebak in action in some of my scripts, doesn't seem to work.
Doing import and install() in entry points of my scripts. It imports the module, but traceback stays the same

Done the same thing in Python shell, just to show the screenshot here
Should it work in Python shell btw?

I might be doing something wrong but this is what I see:

The script:

#!/usr/bin/env python3
"""CRASH!"""

#import stackprinter
#stackprinter.set_excepthook(style='darkbg2')  # for jupyter notebooks try style='lightbg'

try:
    import pretty_traceback
    #pretty_traceback.install(envvar='ENABLE_PRETTY_TRACEBACK')
    pretty_traceback.install()
except ImportError:
    pass    # no need to fail because of missing dev dependency


def main():
    1 / 0


if __name__ == "__main__":
    main()

Hello,

I tried the example code posted at #2 and the library worked fine.
However, trying to code with decorators doesn't seem to be working.

Thanks in advance.
