I created a project using yo webapp (with the generator-webapp installed obviously).
Everything is fine, but I'm still missing something. I'm sure it's such an easy answer that I'll never come back to SO because I'll be too embarrassed.
I want to use Compass, which comes out of the box with Yeoman, but I don't know how. I mean, obviously #import "compass...etc" inside any Sass files won't work since inside app/bower_components (the default path for Sass #imports specified inside Gruntfile.js) there's no compass directory.
What should I do now in order to import Compass stylesheets?
You can use compass just as you would usually do. If you set up a vanilla compass project with compass create, there is compass folder either. If you want to use any of the helpers compass ships with, you can import them just as described in the documentation, e.g.
#import "compass/css3";
.mybox {
#include box-shadow(red 2px 2px 10px);
}
main.scss
You would have to install grunt task for compass with npm install grunt-contrib-compass and adjust your Gruntfile.js to add a task for compass compilation.
It may appear not that easy since it has some tricky parts like to compile your sass to .temp/main.css to use for testing/livereload, and then minify it into your dist when doing final build.
The most easy way might be to just try another generator that has compass in a separate directory. For example angular generator has compass and even bootstrap for compass. It's pretty cool.

While I was learning SASS, I have learned how to install SASS and dev-dependencies using npm package.
Now I want to work on my own project, so how should I work with SASS ?
Do I have to install SASS again ?
If not then how to use existing sass in my project and also the other dependencies like concatenation, auto pre-fixer. Especially when they are updated.
I've npm installed the latest node-sass, and scss files work fine until I use #use. I have a _tokens.scss file in /shared/tokens/ folder. Within _tokens.scss I have:
$colorwhite: #ffffff;
In my root folder, my App.scss looks like this:
#use "shared/tokens/tokens";
.App-header {
color: tokens.$colorwhite;
}
But I am getting this error:
./src/App.scss (./node_modules/css-loader/dist/cjs.js??ref--6-oneOf-5-1!./node_modules/postcss-loader/src??postcss!./node_modules/resolve-url-loader??ref--6-oneOf-5-3!./node_modules/sass-loader/dist/cjs.js??ref--6-oneOf-5-4!./src/App.scss)
SassError: Invalid CSS after " color: tokens": expected expression (e.g. 1px, bold), was ".$colorwhite;"
on line 26 of /Users/xxx/src/App.scss
>> color: tokens.$colorwhite;
Any ideas?
Edit: it works fine with #import. I've also tried #use... as * but no-go.
Update:
Since Node Sass is now deprecated, you can migrate to Dart Sass by replacing node-sass with sass in your package.json and so you will be able to use the #use and #forward rules.
You can use the migration tool to help you with the update.
Original answer:
The #use rule is currently only supported by Dart Sass. You should use #import instead.
You could switch to Dart Sass by taking advantage of package-aliasing. I guess this will not work under yarn.
First you remove the current node-sass pkg, then run:
npm install node-sass#npm:sass.
And you are fit to use the full features from sass with some remarks though.
Check the behavioral diffs here.
The performance measurement indicates that dart-sass is slower than node-sass.
It's all up to you and this turns to be a valid option here, if you really want to use these features provided by Sass.
I've been using Compass to compile Sass in my project, but it is now deprecated and no longer maintained so I want to move away from using Compass. The project uses PHP and Laravel, so I would like to use Laravel Elixir for compiling the Sass files instead.
Is there a way to transfer my .scss files from Compass to Elixir without going in and changing all the places in my Sass code that I use Compass helpers, or do I need to more or less re-write my Sass files? There are a ton of them, so I would love to avoid that.
On the suggestion of my co-worker, what I tried was to add the compass files to my resources/assets/sass directory (includes compass/css3, compass/layout, compass/reset, compass/typography, and compass/utilities, as well as several other .scss files included in Compass. The hope was that by including these files, the functions of Compass would still apply outside of it.
When I try to compile with gulp, the error I'm currently getting (although I'm guess I'll run into another one once this is fixed) is:
>> Sass Compilation Failed: resources/assets/sass/compass/_support.scss
Error: Undefined operation: "prefix-usage(browser-prefixes(browsers()), css-transitions, (full-support: true), (partial-support: true)) gt 0.1".
on line 324 of resources/assets/sass/compass/_support.scss
>> #if $usage > $threshold {
------^
My guess is that I will need to go ahead and remove the Compass stuff from the Sass code manually, but I'm hoping someone else has a better solution for me! Thanks.
ColorZilla's gradient editor says
// needs latest Compass, add '#import "compass"' to your scss
Well I've found that's not so easy. Obviously if you just throw #import "compass"; at the top of your .scss file, Sass won't compile because _compass.scss can't be found.
This is an asp.net project utilizing Sass. In addition, I have to use the sass ruby gem to compile, not compass's compiler.
I've installed the compass gem. I've followed the instructions on http://compass-style.org/install/. I've run compass init, compass create, compass install. None of them even give me compass's mixins.
I expected this to work like bourbon, though I know this isn't compass's primary goal.
What am I missing?
Install the library
bower install compass-sass-mixins
Import the compass into your SASS file
#import "bower_components/compass-sass-mixins/lib/compass"
Checkout SASS function list:

I'm trying to use Twitter Bootstrap for SASS, but at the moment it's not integrated into a Rails project, and I don't I need the stuff I'd get from Compass. I (think I) want a Ruby script that will generate my CSS, JS and Font files and put them in the right places, but having spent a couple of hours going round in circles with the docs, I can't figure this out.
I have a directory like:
site/
css/
bootstrap_variables.scss
application.scss
site.scss
fonts/
index.html
js/
css/bootstrap_variables.scss contains my custom variations on Bootstrap's default variables.
css/site.scss contains the site-specific, non-Bootstrap, CSS.
css/application.scss looks something like this:
#import "bootstrap_variables.scss";
// Import Bootstrap modules I need, but not others.
#import "bootstrap/variables";
#import "bootstrap/mixins";
// ... etc
#import "site.scss"
I've installed the bootstrap-sass gem. And now I want a script that does:
Process css/application.scss with SASS and outputs css/application.css.
Put the Bootstrap JavaScript I need into a single file in js/. (How do I specify which JS modules I need?)
If I'm using Bootstrap's icons, put the glyphicons fonts in fonts/.
If this sounds like madness, and I'm going about this entirely wrong, feel free to tell me that too!
And now I want a script that does:
I'm not sure why you need this script at all. Cause if you can run the script you also can install sass and run sass css/application.scss css/application.css. You can install all bootstrap's file in your site folder by running bower install bootstrap-sass and then run the sass command with --load-path option which should point to your bower_components folder. You can also copy / or link the required javascripts and font from the bower_components folder.
Or consider to use Gulp or Grunt to set up your build chain.
But you can use Sass programmatically indeed.
Process css/application.scss with SASS and outputs css/application.css.
Your script.rb should look something like that shown below:
/usr/bin/env ruby
require 'sass'
require 'bootstrap-sass'
sass_engine = Sass::Engine.for_file('css/application.scss',{
:style => :compact,
:syntax => :scss
})
output = sass_engine.render
File.open("css/application.css", 'w+') {|f| f.write(output) }
Notice that you also should have to integrate the autoprefixer.
Put the Bootstrap JavaScript I need into a single file in js/
After installing the bootstrap-sass gem you can read the javascript files from the gem (see: How to find the path a Ruby Gem is installed at (i.e. Gem.lib_path c.f. Gem.bin_path)).
So the get the content of the affix plugin you can use:
file = File.new(Gem::Specification.find_by_name("bootstrap-sass").gem_dir + "/assets/javascripts/bootstrap/affix.js", "r")
You you can read the required script, concatenate their content, minify and copy
If I'm using Bootstrap's icons, put the glyphicons fonts in fonts/.
As above, copy them from Gem::Specification.find_by_name("bootstrap-sass").gem_dir + "/assets/fonts
