Add or preserve empty line between nested SCSS rules

[alejandroiglesias]

Description

Even though I'm using newline_between_rules, it works only for top level (ie, zero-indented) rules (as confirmed by this changeset for the newline_between_rules PR). It's highly useful for SCSS code to keep newlines also for nested rules, so I think this would be a feature request. Basically, I think that if the newline_between_rules option is true, it should keep the newlines also for the nested rules. Until this gets changed, I sadly need to disable it for my SCSS code.

Input

The code looked like this before beautification:

.list-group {
  .list-group-item {
  }
  
  .list-group-icon {
  }
}

.list-group-condensed {
}

Expected Output

The code should have looked like this after beautification:

.list-group {
  .list-group-item {
  }

  .list-group-icon {
  }
}

.list-group-condensed {
}

Actual Output

The code actually looked like this after beautification:

.list-group {
  .list-group-item {
  }
  .list-group-icon {
  }
}

.list-group-condensed {
}

Steps to Reproduce

Beautify SCSS file with example input.

Environment

VSCode Beautify plugin version 1.1.1.

Settings

Example:

{
    "end_with_newline": true,
    "brace_style": "collapse,preserve-inline",
    "max_preserve_newlines": 2,
    "newline_between_rules": true,
    "space_around_combinator": true,
    "space_after_anon_function": true,
    "wrap_line_length": 100,
    "css": {
        "indent_size": 2
    }
}

This issue is a showstopper for me, would be great to see it fixed - otherwise I am forced to disable SCSS beautification as well.

@davemac - Any help you can provide would be appreciated.

[MarkSky]

Yes, I want this, too.

Now:

.preloader {
	height: 20px;
	.line {
		width: 1px;
		height: 12px;
		background: #38a0e5;
		margin: 0 1px;
		display: inline-block;
		&.line-1 {
			animation-delay: 800ms;
		}
		&.line-2 {
			animation-delay: 600ms;
		}
	}
	div {
		color: #38a0e5;
		font-family: 'Arial', sans-serif;
		font-size: 10px;
		margin: 5px 0;
	}
}

Expected:

.preloader {
    height: 20px;

    .line {
        width: 1px;
        height: 12px;
        background: #38a0e5;
        margin: 0 1px;
        display: inline-block;

        &.line-1 {
            animation-delay: 800ms;
        }

        &.line-2 {
            animation-delay: 600ms;
        }
    }

    div {
        color: #38a0e5;
        font-family: 'Arial', sans-serif;
        font-size: 10px;
        margin: 5px 0;
    }
}

Hope it will supported soon.

I'd like to help fix this issue, but not sure I have the correct skillset. What needs to be done to get this issue resolved?

[bitwiseman]

@davemac
The main skill you need is either Javascript or Python (and a willingness to write a little of the other language). See the Contibuting.md and if that does not have enough information, please help update that with sufficient information for new contributors.

@davemac I suggest you to take a look at original PR 44df1f1

This issue is at least partially addressed in 1.8.0-rc4.
The preserve_newlines setting now works so if there are newlines in the original input the beautifier can be set to not remove them. However, It still does not add the empty line if it is missing.

[MacKLess]

Resolved with the collapsing of empty {}. Here is my output, run on v1.8.0-rc5:

.list-group {
  .list-group-item {}

  .list-group-icon {}
}

.list-group-condensed {}

@alejandroiglesias, please feel free to check it yourself (http://jsbeautifier.org/)

@MarkSky I'm still working on addressing your example. Feel free to look over the code and see what it looks like for you (http://jsbeautifier.org/)

[alejandroiglesias]

@MacKLess thanks for the heads up, it seems to be working as requested according to a quick test with the input I provided, but I'm not using JS Beautifier on an actual project to test thoroughly. Almost a year passed now and I had to find a solution that worked for me. In any case, it seems to be still valuable for a lot of people who requested it.

[alphabt]

I verified that it no longer removes newline on http://jsbeautifier.org (thanks!), but it would be even better if it automatically adds newline.

[MacKLess]

@MarkSky & @iczman

The force newline now appears to be working. Here's the output run on the v1.8.0-rc7 (with my PR):

.preloader {
  height: 20px;

  .line {
    width: 1px;
    height: 12px;
    background: #38a0e5;
    margin: 0 1px;
    display: inline-block;

    &.line-1 {
      animation-delay: 800ms;
    }

    &.line-2 {
      animation-delay: 600ms;
    }
  }

  div {
    color: #38a0e5;
    font-family: 'Arial', sans-serif;
    font-size: 10px;
    margin: 5px 0;
  }
}

If my PR is approved, you should be able to try it out for yourselves. Let me know if this doesn't address the issue.

[shatkovski]

Is there an option to enable the classic behaviour?

I wish to get this output:

.list-group {
  .list-group-item {}
  .list-group-icon {}
}

.list-group-condensed {}

[bitwiseman]

@shatkovski Sorry, there is no setting to get the classic behavior.
It would likely be easy to do.
Please open a new issue requesting it.
