Comparing contents of 2 string (or files), and showing differences

ultranerds has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm trying to achive something like this - with 2 strings:

http://www.travellerspoint.com/wiki_compare.cfm?title=Panama&new_version=25&old_version=23

Is there a "good" way of doing this? Or is it gonna be a case of trying to make use of the `diff` command from command line? (I've used this before, but its made quite difficult to use - as I wanna really split them up into 2 <td> cells, kinda like the example URL above)

TIA

Andy

ultranerds, this is your posting number 86 here, I think it is time your read What shortcuts can I use for linking to other information?, and used it appropriately. To answer your question there's Alogorithm::Diff on CPAN which you might use. If I remember correctly SVN::Web also colors diffs, you might look for prior art there. Also SVN::Notify::HTML::ColorDiff sounds promising. Perl 6 - links to (nearly) everything that is Perl 6.	[reply]

Hi, Thanks for your reply. Re the "help" section, sorry - missed that bit. Didn't realise you could do all that stuff ;) Will try and use it in the future. Regarding those modules etc - I've asked my host to install them, and I'll then give it a go - and see if it will do what I need :) Thanks again Andy	[reply]

Without following your link, does Algorithm::Diff do what you want?	[reply]
