Support terminal and HTML markup

[nichtich]

Right now one must always define DEFAULT_MARKS by hand which is cumbersome. For instance in every script one must write:

use Term::ANSIColor;

%String::Diff::DEFAULT_MARKS = ( 
    remove_open  => color('red'),
    remove_close => color('reset'),
    append_open  => color('green'),
    append_close => color('reset'),
);

This module should provide some default markup settings as easy options, for instance:

    use String::Diff qw(diff html); # sets DEFAULT_MARKS to html
    use String::Diff qw(diff ansi); # sets DEFAULT_MARKS to ansi

    diff($s1,$s2, syntax => 'html');
    diff($s1,$s2, syntax => 'ansi');

I want to reduce the dependence.
If there is a possibility, only to add to the document.

use Term::ANSIColor;
%String::Diff::DEFAULT_MARKS = (
remove_open => color('red'),
remove_close => color('reset'),
append_open => color('green'),
append_close => color('reset'),
);

Term::ANSIColor is a core module, so you don't add any additional dependency. Moreover you can just use fixed strings (also for HTML). Anyway, I use modules for not having to write the same lengthy code to every script. String::Diff should make common use cases (ANSI color markup, HTML markup) quick and simple with a single option or parameter.

You may need OOPish interface.

my $differ = String::Diff->new(
    remove_open => color('red'),
    remove_close => color('reset'),
    append_open => color('green'),
    append_close => color('reset'),
);
my $result = $differ->diff($old, $new);

But I'm too late response...
