generate css from scss - asp.net

I have scss and css files in ASP.NET project.
If I change scss, should be css be regenerated? If yes, then how? VS can do this or should I have some other tool?

There are extensions that allow you to regenerate from inside Visual Studio, but I personally prefer the command line way.
sass --watch [folder holding .scss files]:[folder holding .css files]
If you use Compass, you can use this command instead:
compass watch
Both of these commands will tell Sass to watch the folder with the .scss files, and any time they're changed and saved, regenerate the CSS files.
If you created the project, then you likely already have Sass (and, by extension, Ruby) installed. If you don't, you'll need to install Ruby and Sass. Windows has a nice little installer that installs both Ruby and RubyGems. Once it's installed, you'll need to run the following to install Sass:
gem install sass
Once Sass is installed, you can either run the sass --watch command, or use a VS extension of your choice to watch and recompile the CSS files.

How to compile SASS .scss files in most basic method (without framework)

I installed Bootstrap CSS with SASS from the following repo:
https://github.com/twbs/bootstrap-sass
I ran the command "bower install bootstrap-sass" on the command line and this successfully installed the folder bower_components on my project folder. (Incidentally - I have nothing else present yet, I want to learn to bootstrap the CSS compiling first).
OK, here's what I want to accomplish:
I want to be able to add .scss files to the folder I create called resources/assets/sass/
I want to provision/manage so that .scss files I add to this directory are in turn compiled to public/build/css/that_file_name.css
More practically, I would like to compile all of the .scss files into one large .css file.
My question(s) are:
What does the compiling?
How do I instruct it to compile the .scss files in the folder above in the public/build/css/ folder?
Must I configure new .scss files or can I set it so as to just add them to that sass folder?
Bonus, how do I tell it to minify the output file, or not (so I can experiment with both ways)?
What does the compiling?
Compiling Sass files transforms stylesheets with Sass-specific syntax like selector nesting and mixins into normal CSS that can be parsed by browsers.
How do I instruct it to compile the .scss files in the folder above in the public/build/css/ folder?
Since you're already using Bower which is a Node.js package, I assume that you have no problem using the Node.js package node-sass instead of the original Ruby version.
First, install the package using npm i -D node-sass. Then, create a new script inside your project's package.json:
"compile-sass": "node-sass resources/assets/sass/main.scss public/build/css/main.css"
main.scss is now your entry point where you import Bootstrap and your other stylesheets.
// I don't know whether this path is correct
// Just find out the location of "_bootstrap.scss" and then create the relative path
#import "../../../bower_components/bootstrap-sass/assets/stylesheets/_bootstrap.scss";
/* Your custom SCSS */
Finally, to actually run the compilation, execute npm run compile-sass in your terminal.
Must I configure new .scss files or can I set it so as to just add them to that sass folder?
Since you never tell node-sass to "compile everything inside this folder" and instead use an entry point file (main.js), when you want to include a new file you simply add an #import directive with a relative path to it.
Bonus, how do I tell it to minify the output file, or not (so I can experiment with both ways)?
To minify the resulting main.css file, I recommend csso. You can install its CLI package using npm i -D csso-cli and then add another script to your package.json:
"minify-css": "csso public/build/css/main.css public/build/css/main.min.css"
You can then run that script using npm run minify-css. The minified file will be outputted as main.min.css.
For all the question asked, the answer can be found above. But if you are just looking to compile .scss file to .css using command line, use below,
sass source/stylesheets/index.scss build/stylesheets/index.css
Make sure you have "node JS/npm" and Sass compiler installed.
If not, use this to install Node.js and npm - https://www.npmjs.com/get-npm
And use this to install Sass - https://sass-lang.com/install
Enjoy ;)

Can anyone tell me how to compile sass into css automatically?

I had to rewrite this every time I want to see a live preview.
sass stylesheet.scss stylesheet.css
I use sass --watch stylesheet.scss:stylesheet.css. When saving your .scss file, it'll automatically update the .css file.
You might also consider sass --watch stylesheet.scss:stylesheet.css --style expanded --sourcemap=none to keep the .css file readable.
I'd recommend the Sass Workflow class on Udemy.
Try out Grunt or Gulp with Sass: A great tutorial: https://www.taniarascia.com/getting-started-with-grunt-and-sass/
You need something to compile it automatically. As an example, there are solutions that use node.js to automatically compile for you on your computer. One tool is Foundation for Websites by Zurb.
You can install the application which will automatically compile sass for you.
For more information, check out: http://foundation.zurb.com/sites/download.html/
you can use this code
sass --watch file.sass:file.css
or
sass --watch foldersass:foldercss
Sass can be compiled automatically using below command:
sass --watch SASS_SOURCE_PATH:CSS_BUILD_PATH --style=expanded --no-source-map
Where:
SASS_SOURCE_PATH: Path of sass file
CSS_BUILD_PATH: Path of build CSS file. Where do you want to save CSS file
--no-source-map: will not output a map file, which is not readable.
--style=expanded: will expand CSS to human readable.

Sass --watch only compiling initially

I have Sass v 3.3.6 installed on a ruby project. I'm running the command:
sass --watch assets/sass/
which upon running, compiles the sass files in the sass folder into css files in the folder. However, if I make any changes to the sass files without re-running the above command, the css files don't update. I thought that the --watch command auto-updated upon changes. What am I doing wrong?

Sass not compiling in textmate

I'm trying to use SASS for the first time with textmate. I seem to have installed it correctly by following the instructions on the git page - https://github.com/MarioRicalde/SCSS.tmbundle
but I can't find any information on how I can now use it.
When I make a .sass file the new Sass syntax is highlighted but when I save it is not compiled. Am I missing something?
Make sure to open up Terminal and in the command line, navigate to your project folder and run this command:
sass --watch style.scss:style.css
Name your working file style.scss, and it will compile and generate and update the style.css file that you reference in your document head.
Also make sure you have installed the Sass gem within your project directory :)
gem install sass
UPDATE
The bundle is only for installing syntax highlighting in Textmate. Sass is a precompiler for CSS, so it generates CSS from what you write in Sass. This is done through the sass --watch command above in the command line.

Foundation 4 sass --watch issue

Brand spanking new to foundation 4,
I've installed all dependancies, compass, sass, and zurb-foundation.
ran compass create testproject -r zurb-foundation --using foundation --syntax sass
... worked fine.
ran sass --watch sass:css in the testproject directory and I keep getting errors like so...
error /Users/figmints/Sites/testssss/sass/app.sass (Line 5: File to import not found or unreadable: normalize.
Load paths:
/Users/system/Sites/testproject
/Users/system/Sites/testproject/sass)
In the config.rb, the first line is require 'zurb-foundation'
Isn't this supposed to make the file normalize.scss visible to the project so that I do not have to copy each file located in my gems folder?
Could anyone direct me towards my mistake, please?
Thanks,
Seth
As far as I know, there's no sass watch. What you need to do is:
Navigate to your project's root folder (which is where your Compass project's config.rb should be) through your terminal
Type compass watch and hit Enter
See the magic happen (if you have nicely configured your config.rb, that is)
A Compass project should be watched by Compass. The watch function is why—IMO—Compass is so nice: it does something Sass naturally doesn't do.
Have you tried compiling using compass watch in your testproject root directory, instead of compiling with Sass? Because you created your project with Compass, so you should use Compass to compile.
