Tacit

It provides the useful function, tac, which lets you read lines from end of file. It works like the tac command in the shell.

It reads file into a fixed buffer and yields lines orderly, so it is comportable to use on big file, e.g., large log.

Examples

The content of file:

The first line.
The second line.
The last line.

The code:

for line in open(path):
    print line,
print

from tacit import tac

for line in tac(path):
    print line,

The output:

The first line.
The second line.
The last line.

The last line.
The second line.
The first line.
