Possible typo leading to error

[waynetheisinger]

I'm getting:

{ [Error: bower_components/compass-mixins/lib/compass/functions/_lists.scss
  34:12  index out of bounds for `nth($list, $n)`]
  message: 'bower_components/compass-mixins/lib/compass/functions/_lists.scss\n  34:12  index out of bounds for `nth($list, $n)`',

  showStack: false,

Changing

    @for $i from 2 through length($items) {
      $item: nth($items, $i);
      @if $item != null {
        $full: $full $item;
      }
    }

To

    @for $i from 1 through length($items) {
      $item: nth($items, $i);
      @if $item != null {
        $full: $full $item;
      }
    }

Fixes it... typo?

[waynetheisinger]

actually, this is not just a typo, when I change to 1, I now get the first item in the list twice... column-rule: 1px 1px solid #eee; so you are intending to use 2, not sure why the first is repeated though and not sure how to stop the out of index error if I change to 2 -- I'm now reading up on sass systax in order to debug...

[waynetheisinger]

This seems to do what I want

  @for $i from 1 through length($items) {
      @if $i != 1 {
        $item: nth($items, $i);
        @if $item != null {
          $full: $full $item;
        }
      }
    }

I'm having the same issue with the latest version. The fix by @waynetheisinger works.

[xzyfer]

I think this work around is red herring for the real issue. Sass lists are 1 indexed so nth($list, length($list)) is within bounds. This is not the case for 0 indexed arrays common in other languages.

@xzyfer I'm using the fix by @waynetheisinger on a project temporarily. But I agree, we need to figure out where it's really coming from.
