Flaggie crashes when tty is not initialized

[edannenberg]

Hello,

running Flaggie in a docker container fails with:

Traceback (most recent call last):
  File "/usr/lib/python-exec/python3.10/flaggie", line 8, in <module>
    sys.exit(entry_point())
  File "/usr/lib/python3.10/site-packages/flaggie/__main__.py", line 353, in entry_point
    sys.exit(main(*sys.argv))

  File "/usr/lib/python3.10/site-packages/flaggie/__main__.py", line 191, in <genexpr>

  File "/usr/lib/python3.10/textwrap.py", line 399, in fill
    return w.fill(text)
  File "/usr/lib/python3.10/textwrap.py", line 371, in fill
    return "\n".join(self.wrap(text))
  File "/usr/lib/python3.10/textwrap.py", line 362, in wrap
    return self._wrap_chunks(chunks)
  File "/usr/lib/python3.10/textwrap.py", line 256, in _wrap_chunks
    raise ValueError("invalid width %r (must be > 0)" % self.width)
ValueError: invalid width -2 (must be > 0)

I assumed this was due to a missing tty but the tty binary and docker inspect both say that is not the problem. Digging deeper stty -a gave me the root of the problem:

speed 38400 baud; rows 0; columns 0; line = 0;

Running stty rows 50 cols 80 before flaggie fixes the issues. Could this possibly handled in flaggie gracefully? Thanks!

Thank you for the report. I'll try to fix it and release a version with the fix today.

That did the trick, thanks for the swift fix!
