# readtail
### Simple Description
- A simplest generator function written in pure python
- Seek from the tail of the file
### Install
```shell
pip install tailread
```
### Useage
```python
import tailread as tail
# consuming tails one by one
lines = tail.readlines('access.log')
# take tail of one line
line = next(lines)
print(line)
# b'line 10/r/n'
# next...
line = next(lines)
print(line)
# b'line 9/r/n'
# When passing a fileobject, The file must be opened in bytes mode.
with open('access.log', 'rb'): as fp:
for line in tail.readlines(fp):
print(line)
if 'some string' in line:
break
# or from file path
for line in tail.readlines('access.log'):
print(line)
if 'some string' in line:
break
# b'line 10\r\n'
# b'line 9\r\n'
# b'line 8\r\n'
# b'line 7\r\n'
# ....
```
```python
# decoding lines from encoding info
for line in tail.readlines('access.log', encoding='utf-8', errors='ignore'):
print(line)
# line 10
# line 9
# line 8
# line 7
# ....
```
