multidiff's Issues

UnicodeEncodeError after fresh install

Hello World!

I found your wonderful multidiff from Reddit and wanted to give it a try, but I ran into the following problem:

Running setup as in README:

root@jj:~/multidiff# python3 setup.py install
Traceback (most recent call last):

Can you help?

Please consider naming the commandline multidiff

for sure should not have .py suffix since implementation detail is not important
would make it easier to get started using (I installed multidiff so I use multidiff instead of figuring out what is the cmdline entry point)

Consider making output as wide as the terminal

Possibly making it optional... I would have added --width=auto and did max terminal width if that information is available ... here is code from tqdm

tqdm/_utils.py-def _environ_cols_linux(fp):  # pragma: no cover
tqdm/_utils.py-
tqdm/_utils.py-    try:
tqdm/_utils.py:        from termios import TIOCGWINSZ
tqdm/_utils.py-        from fcntl import ioctl
tqdm/_utils.py-        from array import array
tqdm/_utils.py-    except ImportError:
tqdm/_utils.py-        return None
tqdm/_utils.py-    else:
tqdm/_utils.py-        try:
tqdm/_utils.py:            return array('h', ioctl(fp, TIOCGWINSZ, '\0' * 8))[1]
tqdm/_utils.py-        except:
tqdm/_utils.py-            try:
tqdm/_utils.py-                from os.environ import get
tqdm/_utils.py-            except ImportError:
tqdm/_utils.py-                return None
tqdm/_utils.py-            else:
tqdm/_utils.py-                return int(get('COLUMNS', 1)) - 1

please provide setup.py

and possibly make multidiff into a multidiff Python package while at it ;) It would simplify its distribution (e.g. via pypi), packaging, and (re)use (as a Python module).

large inputs cause hang and never finish

I have install multidiff and I execute the command with window10
“multidiff test1.bin test2.bin”
it doesn't work...
