When I use diff file1 file2, if any text on that line differs from one file to the next it'll print out the entire line. I'd like to see only the text... (2 Replies)

algorithm::diffold
Algorithm::DiffOld(3pm) User Contributed Perl Documentation Algorithm::DiffOld(3pm)
NAME
Algorithm::DiffOld - Compute `intelligent' differences between two files / lists but use the old (<=0.59) interface.
NOTE
This has been provided as part of the Algorithm::Diff package by Ned Konz. This particular module is ONLY for people who HAVE to have the
old interface, which uses a comparison function rather than a key generating function.
Because each of the lines in one array have to be compared with each of the lines in the other array, this does M*N comparisions. This can
be very slow. I clocked it at taking 18 times as long as the stock version of Algorithm::Diff for a 4000-line file. It will get worse
quadratically as array sizes increase.
SYNOPSIS
use Algorithm::DiffOld qw(diff LCS traverse_sequences);
@lcs = LCS( @seq1, @seq2, $comparison_function );
$lcsref = LCS( @seq1, @seq2, $comparison_function );
@diffs = diff( @seq1, @seq2, $comparison_function );
traverse_sequences( @seq1, @seq2,
{ MATCH => $callback,
DISCARD_A => $callback,
DISCARD_B => $callback,
},
$comparison_function );
COMPARISON FUNCTIONS
Each of the main routines should be passed a comparison function. If you aren't passing one in, use Algorithm::Diff instead.
These functions should return a true value when two items should compare as equal.
For instance,
@lcs = LCS( @seq1, @seq2, sub { my ($a, $b) = @_; $a eq $b } );
but if that is all you're doing with your comparison function, just use Algorithm::Diff and let it do this (this is its default).
Or:
sub someFunkyComparisonFunction
{
my ($a, $b) = @_;
$a =~ m{$b};
}
@diffs = diff( @lines, @patterns, &someFunkyComparisonFunction );
which would allow you to diff an array @lines which consists of text lines with an array @patterns which consists of regular expressions.
This is actually the reason I wrote this version -- there is no way to do this with a key generation function as in the stock
Algorithm::Diff.
