## Overview
Simple Python library to perform a 3-way merge between strings, based on [diff-match-patch](https://github.com/google/diff-match-patch). This library performs merges at a character level, as opposed to most VCS systems, which opt for a line-based approach.
## Installing
To install three-merge, you can use both conda or pip package managers:
```bash
# Using conda (Recommended)
conda install three-merge -c spyder-ide
# Using pip
pip install three-merge
```
## Dependencies
This package depends on [diff-match-patch](https://github.com/google/diff-match-patch) to compute and track the differences across the source and target strings with respect to the base one.
## Installing locally
To install and develop three-merge locally, you will need to install diff-match-patch:
```bash
# Using conda
conda install diff-match-patch
# Using pip
pip install diff-match-patch
```
Then, you can install the package locally using pip:
```bash
pip install -U -e .
```
## Running tests
We use pytest to run tests as it follows:
```bash
pytest -x -v three_merge/tests
```
## Package usage
Three-merge provides a ``merge`` function to merge changes from two strings (source, target) with respect a original string (base). This library is able to handle additions, deletions and preserved sections across both strings, while detecting and highlighting possible merge conflicts (like Git).
```python
# Package import
from three_merge import merge
# Strings have non-conflicting additions
base = '123456789101112'
source = '0123456789101112'
target = '12345678910111213'
# merged = '012345678910111213'
merged = merge(source, target, base)
# Strings have an addition conflict
base = '123456789101112'
source = '123a456789101112'
target = '123b456789101112'
# merged = '123<<<<<<< ++ a ======= ++ b >>>>>>>456789101112'
merged = merge(source, target, base)
# Strings have non-conflicting addition/deletions
base = '123456789101112'
source = '123456789ab101112'
target = '123789101112'
# merged = '123789ab101112'
merged = merge(source, target, base)
```
