Compass plugin with various Sass script utility functions. Includes
- Functions to test if a variable, mixing and function exists (these now exist in Sass 3.3 - sass/sass#821)
- Variable interpolation
Make sure you have Compass and Sass 3.3 or greater installed. Sass 3.3 is currently in alpha. To instal the alpha version
sass gem install sass --pre
To install Sass Utilities
sass gem install sass-utilities
Require Sass Utilities into your Compass config.rb
sass require 'sass-utilities'
Don't import the file into your stylesheets. Sass utilities has no .sass or .scss files. If you try to import you will get an error.
$does-exist-var: 'myVar';
// note that you pass in does-exist-var, not $does-exist-var
variable-exists(does-exist-var); // returns true
variable-exists(doesnt-exist-var); // returns false
@mixin mixing-does-exist {
-test: 'I do exist';
}
mixin-exists(mixing-does-exist); // returns true
mixin-exists(mixing-doesnt-exist); // returns false
@function function-does-exist() {
@return 'does-exist'
}
function-exists(function-does-exist); // returns true
function-exists(function-doesnt-exist); // returns false
$color: red;
$fs: 3rem;
// note that you pass in color, not $color
color: interpolate-variable(color);
font-size: interpolate-variable(fs);
color: red;
font-size: 3rem;There will be maps data type in Sass (sass/sass#642) which will mean that some of this functionality may not be necessary. There might still be situtations in which it is desirable (especially as the interpolate funtion doesn't throw an error if the variable doesn't exist, it just returns false).
- Function and mixin interpolation - hopefully sass/sass#626 gets into Sass soon so an extension doesn't have to worry about it.
