I think you are right. Text::Levenshtein is better in this case because String::Approx will match substrings of the input. Here is one more thing. If substitutions are not allowed, only inserts and deletes, you could use Text::WagnerFischer to set the cost of substitution so high that it will not be used.
use Text::Levenshtein; use Text::WagnerFischer; my $pat = 'AAB'; my @lst = qw(ABAB ABBA ABB ABABAAB); my @dist1 = Text::Levenshtein::distance($pat, @lst); my @dist2 = Text::WagnerFischer::distance([0, 1, 100], $pat, @lst); my ($i, $item); $i = 0; foreach $item (@lst) { print "Levenshtein distance of $item to $pat is ",$dist1[$i],"\n"; print "WagnerFischer distance of $item to $pat is ",$dist2[$i],"\n" +; $i++; }

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
