Adding `difflib` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add --dev difflib

to add it a dev dependency (if it's used only in tests, not in the final product). To add it as a regular run-time dependency, run:

cargo add difflib

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

difflib = "0.4.0"

The difflib library will be automatically available globally. Read the difflib library documentation.

Readme

Difflib

Port of Python's difflib library to Rust. It's provide all necessary tools for comparing word sequences.

Installation

Simply add difflib to your dependencies block in Cargo.toml

[dependencies]
difflib = "0.4.0"

Documentation

Documentation is available at https://github.com/DimaKudosh/difflib/wiki

Example

extern crate difflib;

use difflib::differ::Differ;
use difflib::sequencematcher::SequenceMatcher;

fn main() {
    // unified_diff
    let first_text = "one two three four".split(" ").collect::<Vec<&str>>();
    let second_text = "zero one tree four".split(" ").collect::<Vec<&str>>();
    let diff = difflib::unified_diff(
        &first_text,
        &second_text,
        "Original",
        "Current",
        "2005-01-26 23:30:50",
        "2010-04-02 10:20:52",
        3,
    );
    for line in &diff {
        println!("{:?}", line);
    }

    //context_diff
    let diff = difflib::context_diff(
        &first_text,
        &second_text,
        "Original",
        "Current",
        "2005-01-26 23:30:50",
        "2010-04-02 10:20:52",
        3,
    );
    for line in &diff {
        println!("{:?}", line);
    }

    //get_close_matches
    let words = vec!["ape", "apple", "peach", "puppy"];
    let result = difflib::get_close_matches("appel", words, 3, 0.6);
    println!("{:?}", result);

    //Differ examples
    let differ = Differ::new();
    let diff = differ.compare(&first_text, &second_text);
    for line in &diff {
        println!("{:?}", line);
    }

    //SequenceMatcher examples
    let mut matcher = SequenceMatcher::new("one two three four", "zero one tree four");
    let m = matcher.find_longest_match(0, 18, 0, 18);
    println!("{:?}", m);
    let all_matches = matcher.get_matching_blocks();
    println!("{:?}", all_matches);
    let opcode = matcher.get_opcodes();
    println!("{:?}", opcode);
    let grouped_opcodes = matcher.get_grouped_opcodes(2);
    println!("{:?}", grouped_opcodes);
    let ratio = matcher.ratio();
    println!("{:?}", ratio);
    matcher.set_seqs("aaaaa", "aaaab");
    println!("{:?}", matcher.ratio());
