Memory efficient way of reading files line-by-line from the end of file

• Free software: MIT license
• Documentation: https://file-read-backwards.readthedocs.io.

Features

This package is for reading file backward line by line as unicode in a memory efficient manner for both Python 2.7 and Python 3.

It currently supports ascii, latin-1, and utf-8 encodings.

It supports "\r", "\r\n", and "\n" as new lines.

Usage Examples

Another example using python3.11:

from file_read_backwards import FileReadBackwards

with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:

    # getting lines by lines starting from the last line up
    for l in frb:
        print(l)

Another way to consume the file is via readline(), in python3.11:

from file_read_backwards import FileReadBackwards

with FileReadBackwards("/tmp/file", encoding="utf-8") as frb:

    while True:
        l = frb.readline()
        if not l:
            break
        print(l, end="")
