Issue with gulp-css-comb : "Please check the validity"

Question

I'm trying to fix my gulp-ccs-comb task but I have this error :

MacBook-Pro:myProject remy$ gulp sass-comb
[11:23:10] Using gulpfile ~/myproject/gulpfile.js
[11:23:10] Starting 'sass-comb'...
[11:23:10] Finished 'sass-comb' after 5.88 ms

events.js:183
      throw er; // Unhandled 'error' event
      ^

Gonzales PE version: 3.0.0-28

SCSS file :

$list: margin padding;
$listPosition: top bottom left right;

@each $className in $list {
  @for $i from 0 through 100 {
    @if $i % 5 == 0 {
      @each $positionName in $listPosition {
        .#{$className}#{$positionName}-#{$i} {
          #{$className}-#{$positionName}: #{$i}px !important;
        }
      }
      .#{$className}-#{$i} {
        #{$className}: #{$i}px !important;
      }
    }
  }
}

What I am doing wrong in my scss syntax ?

Thank you for your help :)

Answer 1

Try to change @for and @if to @while.

$list: margin padding;
$listPosition: top bottom left right;

@each $className in $list {
  $i: 0;
  @while $i <= 100 {
    @each $positionName in $listPosition {
      .#{$className}#{$positionName}-#{$i} {
        #{$className}-#{$positionName}: #{$i}px !important;
      }
    }
    .#{$className}-#{$i} {
      #{$className}: #{$i}px !important;
    }
    $i: $i + 5;
  }
}

It works for me ( as well as your code :)
