simpletail 0.1.2

Read file in reverse order

Before we go into technical details, a note about the license: It’s GPLv3. This practically means that if you use this module, your program needs to be GPLv3. Sorry about that.

Briefly, the following will print my_file backwards:

import sys

from simpletail import ropen

with ropen('my_file') as f:
    for line in f:

It will work on Unix. It will work on Windows. On Python 2 and 3. It will work regardless what kind of line endings you have. It should work with any file encoding (but you need to specify an encoding, see below), but I’m not certain about that; if in your encoding there are multibyte characters that contain the bytes \n or \r, it will probably not work.


ropen(file, bufsize=4096, encoding=None, errors=None,
      newline=None, closefd=True)

ropen() returns a file object. file is usually a file name, but in Python 3 it can be anything open() accepts as a first argument (however wrapping files opened in text mode will probably not work). The file is read from the end in chunks of size bufsize. The rest of the arguments have the meaning they have in the open() built-in function of Python 3, but they will also work in Python 2, with the exception of closefd, which is ignored in Python 2.
