Missing file_obj.xreadlines()

GoogleCodeExporter commented 9 years ago

Any code with xreadlines() is confused by it and breaks:

lines = open('file.txt','r').xreadlines()
for line in lines:
    print line

That alone will not know the type of xreadlines, line, or lines, even though 
xreadlines returns an iterable that returns one line at a time. Basically it's 
an fgets operation on the open file. It's a Python 2.1 thing, so it should be 
in the purview of Shedskin.

No rush since .readlines() works alright, but .xreadlines() is necessary for 
really large file that get read in bit by bit.

so it was an 'easy task' for several months, and it took me 5 mins just now.. 
too bad I had to do it myself :P do note that xreadlines is deprecated, and you 
get about the same result with iter(file) or 'for line in file'. still for 
compatibility it's good to implement this. thanks again for mentioning!
