# Diffing With Patience
|
|
|
|
The default diff algorithm used by Git is pretty good, but it can get
|
|
mislead by larger, complex changesets. The result is a noisier, misaligned
|
|
diff output.
|
|
|
|
If you'd like a diff that is generally a bit cleaner and can afford a little
|
|
slow down (you probably can), you can instead use the `patience` algorithm
|
|
which is described as such:
|
|
|
|
> Patience Diff, instead, focuses its energy on the low-frequency
|
|
> high-content lines which serve as markers or signatures of important
|
|
> content in the text. It is still an LCS-based diff at its core, but with
|
|
> an important difference, as it only considers the longest common
|
|
> subsequence of the signature lines:
|
|
|
|
> Find all lines which occur exactly once on both sides, then do longest
|
|
> common subsequence on those lines, matching them up.
|
|
|
|
You can set this as the default algorithm by adding the following lines to
|
|
your `~/.gitconfig` file:
|
|
|
|
```
|
|
[diff]
|
|
algorithm = patience
|
|
```
|
|
|
|
or it can be set from the command line with:
|
|
|
|
```bash
|
|
$ git config --global diff.algorithm patience
|
|
```
