# prettydiff
[](https://crates.io/crates/prettydiff)
[](https://docs.rs/prettydiff)
Side-by-side diff for two files in Rust. App && Library.
## Examples
### Slice diff
```rust
use prettydiff::diff_slice;
println!("Diff: {}", diff_slice(&[1, 2, 3, 4, 5, 6], &[2, 3, 5, 7]));
println!(
"Diff: {}",
diff_slice(&["q", "a", "b", "x", "c", "d"], &["a", "b", "y", "c", "d", "f"])
);
println!(
"Diff: {}",
diff_slice(&["a", "c", "d", "b"], &["a", "e", "b"])
);
```
Get vector of changes:
```rust
use prettydiff::diff_slice;
assert_eq!(
diff_slice(&["q", "a", "b", "x", "c", "d"], &["a", "b", "y", "c", "d", "f"]).diff,
vec![
DiffOp::Remove(&["q"]),
DiffOp::Equal(&["a", "b"]),
DiffOp::Replace(&["x"], &["y"]),
DiffOp::Equal(&["c", "d"]),
DiffOp::Insert(&["f"]),
]
);
```
### Diff line by chars or words
```rust
use prettydiff::{diff_chars, diff_words};
println!("diff_chars: {}", diff_chars("abefcd", "zadqwc"));
println!(
"diff_chars: {}",
diff_chars(
"The quick brown fox jumps over the lazy dog",
"The quick brown dog leaps over the lazy cat"
)
);
println!(
"diff_chars: {}",
diff_chars(
"The red brown fox jumped over the rolling log",
"The brown spotted fox leaped over the rolling log"
)
);
println!(
"diff_chars: {}",
diff_chars(
"The red brown fox jumped over the rolling log",
"The brown spotted fox leaped over the rolling log"
)
.set_highlight_whitespace(true)
);
println!(
"diff_words: {}",
diff_words(
"The red brown fox jumped over the rolling log",
"The brown spotted fox leaped over the rolling log"
)
);
println!(
"diff_words: {}",
diff_words(
"The quick brown fox jumps over the lazy dog",
"The quick, brown dog leaps over the lazy cat"
)
);
```
### Diff lines
```rust
use prettydiff::diff_lines;
let code1_a = r#"
void func1() {
x += 1
}
void func2() {
x += 2
}
"#;
let code1_b = r#"
void func1(a: u32) {
x += 1
}
void functhreehalves() {
x += 1.5
}
void func2() {
x += 2
}
void func3(){}
"#;
println!("diff_lines:");
println!("{}", diff_lines(code1_a, code1_b));
```
## App
This crate also provides app for side-by-side diff:
```sh
cargo install prettydiff
prettydiff left_file.txt right_file.txt
```
