SASS Theme Generator

this project serves to support the easy creation of themes using sass variables and sources. As the variables are resolved prior to the sources it is not required to import them. It is important to note that all variables should be defined in the variables and not among the sources.

Install & Use

Project level

To install the library at the project level use npm install sass-theme-generator and to generate the theme add 'sass-theme' to a package.json script.

Global level

To install the library at the global level use npm install -g sass-theme-generator and generate the theme by calling sass-theme in the project folder.

The theme.config.json file

The config file for this library is used to override the default values for this plugin and has the following parameters which can be set.

parameter name	type	default value	description
name	string	theme	The root name for the theme files. Setting the name my-company would result in my-company.css, src/my-company_sources.scss & src/my-company_variables.scss
target	string	dist	The target directory for file storage.
sources	string[]	[]	The source files containing the implementation of the themes. These files use the variables as declared in the variables file. These files should not contain variables!
variables	string[]	[]	The files containing the variable declarations. These files should not contain implementations!

Configuration

Given the following directory structure:

/root
 |
 └──/src
     |
     ├──/constructs
     |   ├── _inputs.scss
     |   └── constructs.scss
     |
     ├──/theme
     |   ├── _page.scss
     |   └── theme.scss
     |
     └──/variables
         ├── _color.scss
         ├── _dimensions.scss
         ├── _display.scss
         └── variables.scss

And the required output:

/root
 |
 └──/target
     └──/src
     |   ├── royal_sources.scss
     |   └── royal_variables.scss
     └── royal.css

Then the theme.config.json would then look like:

{
  "variables": [
    "test/variables/variables.scss",
    "test/constructs/constructs.scss"
  ],
  "sources": ["test/theme.scss"],
  "target": "target",
  "name": "royal"
}

Function comment support (1.1.x +)

To create more support for functional css with themes function comments allow the generation of functional classes.

The function comment delimiter is //@fn which is followed by the variable declarations. The pattern delimiter is => which is followed by the pattern where $0 refers to the first variable set, $1 to the second and so on.

If we add a function comment like:

//@fn multiply [ top, right, bottom, left][ s, n, l] => .margin-$0-$1 { margin-$0: $tier__spacing--$1; }

This would result in the comment being substituted by:

.margin-top-s { margin-top: tier__spacing--s; }
.margin-top-n { margin-top: tier__spacing--n; }
.margin-top-l { margin-top: tier__spacing--l; }
.margin-right-s { margin-right: tier__spacing--s; }
.margin-right-n { margin-right: tier__spacing--n; }
.margin-right-l { margin-right: tier__spacing--l; }
.margin-bottom-s { margin-bottom: tier__spacing--s; }
.margin-bottom-n { margin-bottom: tier__spacing--n; }
.margin-bottom-l { margin-bottom: tier__spacing--l; }
.margin-left-s { margin-left: tier__spacing--s; }
.margin-left-n { margin-left: tier__spacing--n; }
.margin-left-l { margin-left: tier__spacing--l; }

Available functions

• multiply: This function creates unique combinations for all variables per set.
• stitch: This function combines the sets nth variable to create n versions of the pattern. All variable sets must be of equal length.
