bpython crashes trying to print large object

vshesh commented 3 months ago

Hi,

Long time user of bpython, first time I got an error:


Traceback (most recent call last):
  File "/usr/local/bin/bpython", line 8, in <module>
    sys.exit(main())
             ^^^^^^

version information

$ bpython
bpython version 0.24 on top of Python 3.12.3 /usr/local/opt/python@3.12/bin/python3.12

I can json.dumps the large object, bpython will just crash on doing it itself though. I am guessing this is because it would take more than one whole screen to print out the object. having bpython die during a session when this happens is quite annoying - can this be fixed?

Please provide a way to reproduce the issue.

here you go the error seems to stem from use of unicode in strings somehow printing the string directly is fine, but embedding it in an object causes issues

$ bpython
>>> def infer(*args):
...     r = []
...     for i in range(10):
...         r.append([{
...             'location': {'type': 'x̄ȳwhr', 'value': [0.12309123, 1.1231312, 2.123123, 3.123213]},
...         }])
...
...     return r
...
>>> infer()
