YamlCSS Converter

Welcome to our YamlCSS Framework, a user-friendly tool designed to simplify web styling without requiring extensive new learning. Leveraging familiar SASS/CSS knowledge, this framework enables seamless translation of YAML configurations into robust CSS/SCSS, facilitating efficient management of variables, mixins, and styling across projects. Whether configuring colors, typography, or complex layouts, our framework empowers developers to enhance productivity and maintainability with minimal effort and maximum impact.

Features:

• Parses YAML files using the js-yaml library.
• Converts the parsed YAML data to CSS styles based on a predefined structure.
• Offers a command-line tool for easy conversion.
• Offers an out-of-the-box SCSS support for nested styling /Mixins/Variables/Functions/Inheritance/Loops/Conditions .

Installation:

1. Clone this repository or download the zip file. Or Install globally via a package manager:

   npm install -g https://github.com/neon-x-hub/yaml-css.git

Usage:

1. Create a YAML file: Define your styles in a YAML file (e.g., styles.yaml). Refer to the example structure below.

2. Run the script: Execute the script using the command line:

   ycss input.yaml output.scss

   • Replace input.yaml with your actual file name.
   • Replace output.scss with your desired output file name for the generated CSS/SCSS.

Feature with some examples

Note:

If any key or value strings in the YAML configuration contain special characters, ensure they are wrapped in double quotes ("). This helps maintain correct interpretation and processing when translating into SCSS.

1. Variables

YAML:

variables:
  primary-color: '#3498db'
  padding: '10px'
  font-sizes: [10px, 20px, 30px]
  theme-colors:
    primary: '#3498db'
    secondary: '#2ecc71'
    danger: '#e74c3c'
  colors:
    - red
    - green
    - blue

SCSS:

$primary-color: #3498db;
$padding: 10px;
$font-sizes: (10px, 20px, 30px);
$theme-colors: (primary: #3498db, secondary: #2ecc71, danger: #e74c3c);
$colors: (red, green, blue);

2. Mixins

YAML:

# You can define a set of mixins
mixins:
  box:
    padding: $padding
    border: 1px solid $primary-color
  chip:
    padding: $padding
    border-radius: 9999px
# Or you can define each mixin individually with the "mxn" keyword
mxn box2:
  padding: $padding
  border: 1px solid $primaryColor

SCSS:

@mixin box {
  padding: $padding;
  border: 1px solid $primary-color;
}
@mixin chip {
  padding: $padding;
  border-radius: 9999px;
}
@mixin box2 {
  padding: $padding;
  border: 1px solid $primaryColor;
}

3. Functions

YAML:

# You can define a set of functions
functions:
  darken:
    - [color, amount] # Params
    - | # Body
       @return mix(black, $color, $amount);

# Or you can define each function individually with "func" keyword
func lighten:
  - [color, amount]
  - |
     @return mix(white, $color, $amount);

SCSS:

@function darken ($color, $amount) {
  @return mix(black, $color, $amount);
  
}
@function lighten($color, $amount) {
  @return mix(white, $color, $amount);
  
}

4. Styles By Tag, Classes and IDs

YAML:

h1:
  font-size: 24px
  font-weight: bold
  color: green
  "&:hover":
    color: blue

.class :
  color: red
  font-size: 16px
  font-weight: bold
  text-decoration: underline
  "&:before" :
    color: blue

"#id":
  color: blue
  font-weight: bold
  text-decoration: none
  "&:hover":
    text-decoration: underline

SCSS:

h1 {
  font-size: 24px;
  font-weight: bold;
  color: green;
  &:hover {
    color: blue;
  }
}
.class {
  color: red;
  font-size: 16px;
  font-weight: bold;
  text-decoration: underline;
  &:before {
    color: blue;
  }
}
#id {
  color: blue;
  font-weight: bold;
  text-decoration: none;
  &:hover {
    text-decoration: underline;
  }
}

CSS:

h1 {
  font-size: 24px;
  font-weight: bold;
  color: green;
}
h1:hover {
  color: blue;
}

.class {
  color: red;
  font-size: 16px;
  font-weight: bold;
  text-decoration: underline;
}
.class:before {
  color: blue;
}

#id {
  color: blue;
  font-weight: bold;
  text-decoration: none;
}
#id:hover {
  text-decoration: underline;
}

5. Support for CSS @ Rules (e.g. @supports, @media ...etc)

Supported tags are 'media', 'font-face', 'keyframes', 'supports', 'document', 'page', 'namespace'

YAML:

supports (display:grid):
  .grid-container:
    display: grid

CSS/SCSS:

@supports (display: grid) {
  .grid-container {
    display: grid;
  }
}

6. The @use Sass rule

YAML:

use:
  - sass:map
  - m: sass:math

SCSS

@use 'sass:map';
@use 'sass:math' as m;

7. Nested Selector with Mixin (nav ul li a)

YAML:

nav:
  ul:
    margin: 0
    padding: 0
    list-style: none
    li:
      display: inline-block
      include: chip
      a:
        text-decoration: none
        color: $primary-color
        include: box

SCSS:

nav {
  ul {
    margin: 0;
    padding: 0;
    list-style: none;
    li {
      display: inline-block;
      @include chip;
      a {
        text-decoration: none;
        color: $primary-color;
        @include box;
      }
    }
  }
}

CSS:

nav ul {
  margin: 0;
  padding: 0;
  list-style: none;
}
nav ul li {
  display: inline-block;
  padding: 10px;
  border-radius: 9999px;
}
nav ul li a {
  text-decoration: none;
  color: #3498db;
  padding: 10px;
  border: 1px solid #3498db;
}

8. Extend Selector - Inheritance (.nav-item)

YAML:

.nav-item:
  extend: base-style
  background-color: "#f5f5f5"

.base-style:
  color: $primary-color
  margin: $padding

SCSS:

.nav-item {
  @extend .base-style;
  background-color: #f5f5f5;
}

.base-style {
  color: $primary-color;
  margin: $padding;
}

CSS:

/* Doesn't scale well!! */

.nav-item {
  background-color: #f5f5f5;
}

.base-style, .nav-item {
  color: #3498db;
  margin: 10px;
}

9. Looping through Colors (@each)

YAML:

each $color in $colors:
  .color-#{$color}:
    color: $color

each $color $value in $theme-colors: # With maps
  .text-#{$color}:
    color: $value

SCSS:

@each $color in $colors {
  .color-#{$color} {
    color: $color;
  }
}

@each $color, $value in $theme-colors { // With maps
  .text-#{$color} {
    color: $value;
  }
}

CSS:

.color-red {
  color: "red";
}

.color-green {
  color: "green";
}

.color-blue {
  color: "blue";
}

/* With maps */

.text-primary {
  color: #3498db;
}

.text-secondary {
  color: #2ecc71;
}

.text-danger {
  color: #e74c3c;
}

14. Conditional Statements (@if, @else if, @else)

YAML:

if $theme == 'dark':
  body:
    background-color: black
    color: white

elif $theme == 'light':
  body:
    background-color: white
    color: black
else:
  body:
    background-color: green
    color: red

SCSS:

@if $theme == 'dark' {
  body {
    background-color: black;
    color: white;
  }
}
@else if $theme == 'light' {
  body {
    background-color: white;
    color: black;
  }
}
@else {
  body {
    background-color: green;
    color: red;
  }
}

15. Loops (@for)

YAML:

.scss:
  for $i in 1..3:
    .font-size-#{$i}:
      font-size: nth($font-sizes, $i)

  for $i in 1..4:
    .padding-#{$i}:
      padding: $i * 10px

SCSS:

.scss {
  @for $i from 1 through 3 {
    .font-size-#{$i} {
      font-size: nth($font-sizes, $i);
    }
  }
  
  @for $i from 1 through 4 {
    .padding-#{$i} {
      padding: $i * 10px;
    }
  }
}

CSS:

.scss .font-size-1 {
  font-size: "10px";
}
.scss .font-size-2 {
  font-size: "20px";
}
.scss .font-size-3 {
  font-size: "30px";
}
.scss .padding-1 {
  padding: 10px;
}
.scss .padding-2 {
  padding: 20px;
}
.scss .padding-3 {
  padding: 30px;
}
.scss .padding-4 {
  padding: 40px;
}
