I tried:
sass-convert --from scss --to css --recursive app/assets/stylesheets temp
But this only converts css to SASS, and I want the other way around.
Then I looked at the sass command, but it doesn't look like I can pass it a directory.
To do a one-time Sass compile instead of a watch, you can do this from the command line:
sass --update scss:css
To have Sass import one file (usually a partial, with a _ starting the filename), you can do this inside a Sass file:
#import "_base.scss";
This way, Sass knows where you want the include to occur.
By default, Sass can't import an entire directory. The Sass Globbing gem, however, can. You can install it from the command line:
gem install sass-globbing
And then watch with it:
sass -r sass-globbing --watch sass_dir:css_dir
Note that globbing will import files alphabetically, so be sure your CSS will cascade appropriately if this occurs.
Use the sass command followed by the input file name and path, a colon (:) and the desired output file name and path. If the output file does not already exist Sass will generate it. For example,
sass sass/main.scss:css/main.css
However, this is a one-off command that would require being run every time you want to generate a new CSS file. A simpler and handier method is to use Sass's built-in --watch flag. This watches for changes to your Sass file and automatically runs the compile command each time you save changes.
sass --watch sass/main.scss:css/main.css
If you have multiple Sass files within a directory you can watch for changes to any file within that directory:
sass --watch sass:css
Sass also has four CSS output styles available: nested, expanded, compact and compressed. These can be used thus:
sass --watch sass:css --style compressed
Refer to the Sass documentation for more.
to that, simply go your project directory and do this :
sass --update sass-dir:assets/css
with sass-dir the directory containing your actual sass files and assets/css the desired output directory.
Hope this could help.
You can use compass to convert Sass files into CSS.
To initialize the config.rb, try:
compass init --syntax=sass --css-dir=css --javascripts-dir=js
Once you've the configuration file, try:
compass compile
or by specifying the file explicitly: compass compile sass/foo.scss.
To install it, try:
sudo gem update
sudo gem install sass compass
https://sass-lang.com/guide
you can use
sass --watch [input folder path]:[output folder path]
i tried running it in a new terminal and after that sass watches the folder and compiles upon any changes.
you can use this code
sass --watch file.sass:file.css
or
sass --watch folderSass:foldercss
if you want to create css.main you can use this code
sass --watch sass:css --style compressed

I am trying to compile my Sass on the Cloud9 (http://c9.io) IDE. I have a Compass config.rb file, which I'd like to be adhered to.
The output of sass -h within the terminal states that a --compass option exists:
mikemike#x:~/workspace/resources/assets/sass (master) $ sass -h compass
Usage: sass [options] [INPUT] [OUTPUT]
Description:
Converts SCSS or Sass files to CSS.
Common Options:
-I, --load-path PATH Specify a Sass import path.
-r, --require LIB Require a Ruby library before running Sass.
--compass Make Compass imports available and load project configuration.
-t, --style NAME Output style. Can be nested (default), compact, compressed, or expanded.
-?, -h, --help Show this help message.
-v, --version Print the Sass version.
I'm unsure how to get this working. There is no additional information on it and simply running sass --compass or sass --compass config.rb just seems to put sass in interactive mode.
The command you just ran is giving you a hint as to how you're supposed to use it. It expects an input and an output. Since you're providing neither, it goes into interactive mode.
You can't specify the location of the config.rb, this is by design. Use the compass command instead (eg. compass watch).
sass --compass is intended to be a quick-and-dirty way to get access to the Compass libraries that don't require any configuration. If you want anything more complicated, you should use the compass executable.

How could I trace changes in whole directory containing many sass files ? I'm using the following command to watch changes in sass
file:
sass --watch style.scss:style.css
But how to watch changes in whole directory/folder containing many sass files.
Simply use the command sass --watch <input folder>:<output folder>, like this:
$ ls -l
css/ sass/
$ sass --watch sass:css
Where <input folder> contains the Sass files and <output folder> that hosts the generated CSS files.
Expanding the answer by piouPiouM a little:
Output files will be created with the same names as input files except ending with .css.
<input folder> and <output folder> can be the same.
Both folders can be the present working directory, so the following is valid:
$ sass --watch .:.
Go to you terminal and get to you folder then wrote:
sass --watch .
this will watch all sass files and convert to css files with the same name.
also you can do it in this way:
sass --watch ~/user/youUser/workspace/project/styles/
I hope this can help you.
I ended up doing this without using Grunt or Sass-watch:
npm install -g watch
watch "sass assets/app.scss assets/dist/app.css" assets/css
if you are in your current folder then do the following to watch it.
F:\sass tutorial>sass --watch ./:./
Just in case someone faces with this issue in 2018:
sass Website refers to Ruby Sass that is been deprecated.
and as now (May 2018) if you install dart sass via npm , it does not support --watch command
What to do:
you need to install node-sass globaly , like:
npm install node-sass -g
and then restart the command line , then use this code:
node-sass --watch scss/styles.scss css/styles.css
to compile your scass files to css.
basically node-sass supports --watch command and we use that to compile our scss codes to regular css files.
and just in case you get an error like this at the first time that you save your .scss file:
{
"status": 3,
"message": "File to read not found or unreadable: yourdirectory/scss/styles.scss",
"formatted": "Internal Error: File to read not found or unreadable: yourdirectory/scss/styles.scss\n"
}
what you need to do is save it again, it will work correctly!
According to the information, you can use the next command line:
sass --watch .
Source: http://sassbreak.com/watch-your-sass/#what-does---watch-do
You can create one sass file which includes the rest of the files, and then just watch this file.
Alternately, look into Grunt and the very good grunt-contrib-compass plugin
You can set sass to watch all the .scss files(for my case i got several .scss files in src/static folder) to compile, but before install it globally:
npm i -g sass
then go to the project folder and type command below:
sass --watch $(pwd)/src/static
also you can wrap it in npm script in package.json, like
"scripts": {
"sass:watch": "sass --watch $(pwd)/src/static"
}
and run it by this command:
npm run sass:watch
I know that I can watch a single file in a folder and have it compressed like so:
sass --watch HealthyArticles.scss:HealthyArticles.min.css --style compressed
What I'd like to be able to do is:
sass --watch *.scss:*.min.css --style compressed
The problem with this is that I get the error:
Errno::EINVAL: Invalid argument - *.scss
The main point is controlling the output filename. Is this possible with sass?
I think you're probably looking for Compass. All this stuff is just baked into Rails, so I'm not sure exactly how everything links together, but I believe if you're using SCSS without a framework around it, then Compass is what you're after.
Download from http://compass-style.org/ and run something like this:
gem install compass
$ compass create asd --bare --sass-dir "input_directory" --css-dir "output_directory"
You can set this in a config file:
output_style = :compressed
Alternatively, you could just run a script that does something like (this is Ruby):
files = Dir["/path/to/scss/folder/*.scss"].map do |file|
"#{file}:#{file.gsub(".scss", ".min.css")}"
end
`sass --watch #{files} --style compressed`
Is there a way to force Compass to use the Sass syntax instead of SCSS?
For new projects, run:
compass create path/to/project --syntax sass
to generate .sass files using Sass syntax inside the sass folder. The --syntax option and others are listed when you run compass --help.
For existing projects, add the following to your Compass config.rb:
preferred_syntax = :sass
That's covered in the Compass configuration reference. And you'll want to run your existing SCSS files through sass-convert to generate new ones which use Sass syntax.
I'd like to use Sass with Compass on my static HTML project, but following the instructions does not work. This is what I did:
$ gem install compass
$ cd <myproject>
$ compass install compass .
which was following by awaiting:
directory ./sass/
directory ./stylesheets/
create ./sass/screen.scss
create ./sass/print.scss
create ./sass/ie.scss
create ./stylesheets/screen.css
create ./stylesheets/ie.css
create ./stylesheets/print.css
But when I start watching scss sass --watch sass:stylesheets, I get an error:
error sass/screen.scss (Line 6: File to import not found or unreadable: compass/reset.
This msg coherent with #import "compass/reset";
What do I have to do on my Ubuntu to see that compass imports?
Use compass watch instead of sass --watch sass:stylesheets. If you're using compass, you don't need to bother with sass command. Just use the compass command.
if you really wanted to use sass command i use this code. Considering that you are in your sass directory running the following command.
sass --watch style.scss:../stylesheets/
That simply means that I have created a new file called style.scss and imported the following files within my style.scss. So sass would only watch a single file. In the above command we wishes to have the generated style.css to be in the stylesheet directory.
again its sass --watch style.scss:/path-to-output-directory/
#import "ie";
#import "print";
#import "screen";
so in this process sass is only watching single file style.scss for any changes within sass directory files.
I hope this explains well.
