Sass: Watch multiple input-files for one output-file [duplicate] - sass

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

--watch command is obsolete?

--watch command
no longer works for scss. What's the equivalent
Bought a new pc and can't get newest version of sass to compile
This is going to be marked as duplicate but please point me in right direction
No, I don't think so.
As the official SASS website explained, you can use --watch command like this:
sass --watch <input file or folder>:<output file or folder>
To install sass on your new machine you can use this command:
npm install -g sass

Compile everything in scss folder to style.css via terminal

I have the following folder structure:
theme
scss
hero.scss
header.scss
style.css
I'm trying to compile everything in the scss into style.css. I've followed this tutorial, but I believe this approach will compile several different css files (whereas I only want the one).
Even with the above approach, whenever I run npm run scss, it doesn't compile anything?
This is my package.json file:
{
"name": "test",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"scss": "node-sass --watch scss -o css"
},
"author": "",
"license": "ISC"
}
When running npm run watch-css or npm run scss, nothing happens? Where am I going wrong?
Your input directory and output directories are incorrect for the node-sass command. Assuming you've the following directory structure:
theme
scss
hero.scss
header.scss
style.css
package.json
You've created an npm run script called scss which is leveraging the node-sass library to compile your SASS into CSS. If you want to execute this run script you should type the following into your command line: npm run scss
Now when you type this command you're actually running the node-sass library with these parameters:
node-sass --watch scss -o css
In this command, you've specified that your Sass files exist in your scss directory and node-sass should look in this directory to compile your Sass into CSS. Once this is done your newly generated CSS is moved into your css directory.
However, the first issue is you don't have css directory for node-sass to put these compiled Sass files into. You can remedy this by either creating a css folder within your theme directory or modifying your output location parameter appropriately.
The other issue is your input directory location is incorrect for your Sass files. You've specified it as the scss directory however this location is relative to your package.json file and there is theme folder in-between said files. This should probably be changed to the following: theme/scss.
So in order to get it this command to work appropriately you need to change your input and output directories to point to the correct directory structure of your application.
Perhaps you could try changing your run script to the following and seeing if this helps (Assuming you don't want to create a css folder):
"scss": "node-sass --watch theme/scss -o theme"
then re-run your npm script like so:
npm run scss
Hopefully that helps!

Error while trying to compile directory with .scss files

I simply want to compile the whole directory with .scss files like it is in docs but I get an error, what am I doing wrong?
The command is: sass scss:public/main.css but I get this error:
Errno: EISDIR: Is a directory # rb_sysopen scss Use --trace for backtrace
The Sass documentation shows no such usage for compiling with the sass command. You cannot compile a directory to a single file.
You can also tell Sass to watch the file and update the CSS every time
the Sass file changes:
sass --watch input.scss:output.css
If you have a directory with many Sass files, you can also tell Sass
to watch the entire directory:
sass --watch app/sass:public/stylesheets

How to convert directory SASS/SCSS to CSS via command line?

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

sass watch files in folder and minify, but control output filename

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`
