Package: pydf
Version: 9
Severity: normal
Using pydf in Emacs shell buffers fails like this:
$ pydf
Traceback (most recent call last):
File "/usr/bin/pydf", line 644, in <module>
display_table(table, terminal_width)
File "/usr/bin/pydf", line 534, in display_table
squeeze_table(table, terminal_width-1)
File "/usr/bin/pydf", line 482, in squeeze_table
colsize = len(row[col][1])
ValueError: __len__() should return >= 0
$
That's because the termios detection routine appears to work, but
returns zero. When running inside Emacs, the best way to detect the
terminal width is probably to use COLUMNS, both shell mode and term mode
set it:

Thanks.
