cdifflib
========
[<img src="https://travis-ci.org/mduggan/cdifflib.svg?branch=master">](https://travis-ci.org/mduggan/cdifflib/)
Python [difflib](http://docs.python.org/2/library/difflib.html) sequence
matcher reimplemented in C.
Actually only contains reimplemented parts. Creates a `CSequenceMatcher` type
which inherets most functions from `difflib.SequenceMatcher`.
`cdifflib` is about 4x the speed of the pure python `difflib` when diffing
large streams.
Limitations
-----------
The C part of the code can only work on `list` rather than generic iterables,
so anything that isn't a `list` will be converted to `list` in the
`CSequenceMatcher` constructor. This may cause undesirable behavior if you're
not expecting it.
Works with Python 2.7 and 3.6 (Should work on all 3.3+)
Usage
-----
Can be used just like the `difflib.SequenceMatcher` as long as you pass lists. These examples are right out of the [difflib docs](http://docs.python.org/2/library/difflib.html):
```Python
>>> from cdifflib import CSequenceMatcher
>>> s = CSequenceMatcher(None, ' abcd', 'abcd abcd')
>>> s.find_longest_match(0, 5, 0, 9)
Match(a=1, b=0, size=4)
>>> s = CSequenceMatcher(lambda x: x == " ",
... "private Thread currentThread;",
... "private volatile Thread currentThread;")
>>> print round(s.ratio(), 3)
0.866
```
It's completely compatible, so you can replace the difflib version on startup
and then other libraries will use CSequenceMatcher too, eg:
```Python
from cdifflib import CSequenceMatcher
import difflib
difflib.SequenceMatcher = CSequenceMatcher
import library_that_uses_difflib
# Now the library will transparantely be using the C SequenceMatcher - other
# things remain the same
library_that_uses_difflib.do_some_diffing()
```
Making
------
Set up a venv:
```
python -m venv .venv
source .venv/bin/activate
```
To install:
```
python -m build
```
To test:
```
python -m pytest tests/cdifflib_tests.py
```
