Convert Sass to SCSS

libsass/sassc require SCSS. This is an experiment at writing a really barebones Sass to SCSS converter. Hopefully if this experiment works out, I can rewrite it in C and use it in a patch to libsass.

Supports

• automatic semicolon ; insertion
• automatic opening and closing curly brace {} insertion
• @import bourbon/bourbon => @import "bourbon/bourbon"
• = => mixin
• + => include

Usage

Convert asdf.sass to asdf.scss: python sass_to_scss.py asdf.sass

Options:

usage: sass_to_scss.py [-h] [--spaces SPACES] 9[--debug] file

Convert a Sass file to SCSS.

positional arguments:
  file

optional arguments:
  -h, --help       show this help message and exit
  --spaces SPACES  number of spaces used for indentation
  --debug          output debug information

Example

Turn this beautiful Sass:

@import bourbon/bourbon
@import "http://fonts.googleapis.com/css?family=PT+Serif:400,700,400italic,700italic|Oswald:400,300,700|Droid+Sans:400,700"

$teal: #00917d
$serif: 'PT Serif', serif

=red-text
    color: red
    background-color: $teal

=rounded($amount, $background_color)
    -moz-border-radius: $amount
    -webkit-border-radius: $amount
    border-radius: $amount
    background-color: saturate(lighten($background_color, 30%), 100%)

.error
    +red-text
    .details
        border: 3px solid #777
        +rounded(0.5em, desaturate(#5336a2, 10%))

.container
    position: absolute
    top: 0
    color: green
    bottom: 0

    .right, .row:hover, &.touch .row
        right: 0
        border: 1px solid #fff
        h1
            color: blue
    .left
        left: 0
        h1
            color: red

into this less beautiful SCSS:

@import "bourbon/bourbon";
@import "http://fonts.googleapis.com/css?family=PT+Serif:400,700,400italic,700italic|Oswald:400,300,700|Droid+Sans:400,700";
$teal: #00917d;
$serif: 'PT Serif', serif;
@mixin red-text {
    color: red;
    background-color: $teal;
}
@mixin rounded($amount, $background_color) {
    -moz-border-radius: $amount;
    -webkit-border-radius: $amount;
    border-radius: $amount;
    background-color: saturate(lighten($background_color, 30%), 100%);
}
.error {
    @include red-text;
    .details {
        border: 3px solid #777;
        @include rounded(0.5em, desaturate(#5336a2, 10%));
    }
}
.container {
    position: absolute;
    top: 0;
    color: green;
    bottom: 0;
    .right, .row:hover, &.touch .row {
        right: 0;
        border: 1px solid #fff;
        h1 {
            color: blue;
        }
    }
    .left {
        left: 0;
        h1 {
            color: red;
        }
    }
}
