This is somewhat embarassing, since I'm sure the answer to this question is to be found in many good perl books. But I suspect the answer is probably pretty simple to someone who has the "perl mentality", so I'm hoping your replies will aid me in gaining said mentality. I used to program Tcl, and since changing to perl, often find myself wanting an 'lsearch' function. I tend to add it so:

sub lsearch {
  my $item = shift;
  my @array = @_;
  foreach (0..$#array) {
    if ($item eq $array[$_]) {
      return $_;
    }
  }
  return "";
}

# Want to remove $item from @list
unless (my $index = lsearch($item, @list) eq "") {
  splice(@list, $index, 1);
}

I think that in some cases where I used to use 'lsearch', I could now be using 'grep', but what do you do when you want the index of an item in your list? Or do you just program to avoid such cases?

• 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).
