Diff::LCS

RubyGems Version Coveralls
Build Status

Description

Diff::LCS computes the difference between two Enumerable sequences using the
McIlroy-Hunt longest common subsequence (LCS) algorithm. It includes utilities
to create a simple HTML diff output format and a standard diff-like tool.

This is release 2.0, which has significant breaking changes (removal of
deprecations and workarounds) and requires at least Ruby 3.2 or higher. See full
details in the CHANGELOG, but users of diff-lcs should not notice any
significant changes to the APIs.

Performance and Compatibility

I have not run any benchmarks, but the use of immutable Data classes and the
removal of a number of inner loop conditionals related to encoding and String
handling (which have been unnecessary since at least Ruby 2.1 but kept for
strict compatibility) should allow better optimization by modern Ruby
implementations.

If you are using RSpec for your test suite, you are unlikely to be able to use
Diff::LCS 2.0 because of the minimum Ruby version unless the developers of RSpec
loosen their version constraints. I cannot control this and have raised
rspec/rspec#290.

Synopsis

Using this module is quite simple. By default, Diff::LCS does not extend objects
with the Diff::LCS interface, but will be called as if it were a function:

require 'diff/lcs'

seq1 = %w(a b c e h j l m n p)
seq2 = %w(b c d e f j k l m r s t)

lcs = Diff::LCS.LCS(seq1, seq2)
diffs = Diff::LCS.diff(seq1, seq2)
sdiff = Diff::LCS.sdiff(seq1, seq2)
seq = Diff::LCS.traverse_sequences(seq1, seq2, callback_obj)
bal = Diff::LCS.traverse_balanced(seq1, seq2, callback_obj)
seq2 == Diff::LCS.patch!(seq1, diffs)
seq1 == Diff::LCS.unpatch!(seq2, diffs)
seq2 == Diff::LCS.patch!(seq1, sdiff)
seq1 == Diff::LCS.unpatch!(seq2, sdiff)

Objects can be extended with Diff::LCS:

seq1.extend(Diff::LCS)
lcs = seq1.lcs(seq2)
diffs = seq1.diff(seq2)
sdiff = seq1.sdiff(seq2)
seq = seq1.traverse_sequences(seq2, callback_obj)
bal = seq1.traverse_balanced(seq2, callback_obj)
seq2 == seq1.patch!(diffs)
seq1 == seq2.unpatch!(diffs)
seq2 == seq1.patch!(sdiff)
seq1 == seq2.unpatch!(sdiff)

By requiring 'diff/lcs/array' or 'diff/lcs/string', Array or String will be
extended for use this way.

Note that Diff::LCS requires a sequenced enumerable container, which means that
the order of enumeration is both predictable and consistent for the same set of
data. While it is theoretically possible to generate a diff for an unordered
hash, it will only be meaningful if the enumeration of the hashes is consistent.
In general, this will mean that containers that behave like String or Array will
perform best.

History

Diff::LCS is a port of Perl's Algorithm::Diff that uses the McIlroy-Hunt longest
common subsequence (LCS) algorithm to compute intelligent differences between
two sequenced enumerable containers. The implementation is based on Mario I.
Wolczko's Smalltalk version 1.2 (1993) and Ned Konz's Perl version
Algorithm::Diff 1.15. Diff::LCS#sdiff and
Diff::LCS#traverse_balanced were originally written for the Perl version by
Mike Schilli.

The algorithm is described in A Fast Algorithm for Computing Longest Common
Subsequences, CACM, vol.20, no.5, pp.350-353, May 1977, with a few minor
improvements to improve the speed. A simplified description of the algorithm,
originally written for the Perl version, was written by Mark-Jason Dominus.
