I start a project where I have this : Site
And I like to do something like this :
: sass --watch Component/*.scss:css/style.css
When a save is done in any .scss in Component/, it run "watch", is that possible ?
Thk for looking;
If you are using the sass gem you have the following options:
update will compile a single file or multiple files in a folder (depending on the parameters). watch will do the same and after the initial compilation is completed it will watch the file or all the files in the specified folder, so everytime a change is detected on any of the target files, sass will compile the changed ones.
Both options have the same command line sintax:
sass --watch input/folder:output/folder
sass --watch input.scss:output.css
So, to compile all the files in a folder:
sass --update path/to/input/folder:path/to/output/folder
And to compile and then watch a folder:
sass --watch path/to/input/folder:path/to/output/folder
Just run sass --help for a complete list of options.
Hope it helps!
Supposing, you use gulp to run the tasks.
var sass = require('gulp-sass'); //after npm i gulp-sass --save-dev in your terminal.
gulp.task('watch', function(){
gulp.watch('./app/sass/*.scss', ['sass']); //place the correct location of your scss folder
});
And include watch in 'build' task
// *** build task *** //
gulp.task('build', function() {
runSequence(
['watch']
);
});
Hope this helps!

I have been struggling with gulp to compile scss files into css.
I havn't used gulp and sass very much and the docs of this particular framework are not helpful on this matter.
My gulpfile looks like this
var gulp = require('gulp');
var sass = require('gulp-sass');
var scssFile='assets/scss/bootstrap-material-design.scss';
gulp.task('sass', function () {
return gulp.src(scssFile)
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('_site/assets/css'));
});
I did npm install gulp gulp-sass --save-dev to install libraries.
And I copied the content of this folder https://github.com/FezVrasta/bootstrap-material-design/tree/master/scss into a folder named "scss"
Now running gulp sass gives me this error:
[13:54:37] Using gulpfile ~/workspace/imb4/gulpfile.js
[13:54:37] Starting 'sass'...
Error in plugin "sass"
Message:
assets/scss/_variables.scss
Error: File to import not found or unreadable: ~bootstrap/scss/functions.
on line 56 of assets/scss/_variables.scss
from line 2 of assets/scss/_core.scss
from line 3 of assets/scss/bootstrap-material-design.scss
>> #import "~bootstrap/scss/functions"; // from bootstrap node_module
^
[13:54:37] Finished 'sass' after 50 ms
Is this because I copied the wrong scss folder ?
Do I need to npm install bootstrap-material-design#4.1.1?
(I did try that, but I can't require() it because it needs jQuery or something.)
Do I need to reference the scss files that are in the node_modules?
The error says it needs a bootstrap folder, do I need to download bootstrap scss files manually and copy them in the folder? Do I have to do npm install bootstrap?
It's probably a stupid question, but I'm already stuck on this for hours now.
Clone the folder in the link as is to your assets/scss
Your gulpfile should call your main entry sass file style.scss - in your case "bootstrap-material-design.scss"
this sass file contains only one import - #import "core";
_core imports _variables.scss, _mixins.scss etc...
your _variables.scss file has
#import "~bootstrap/scss/functions"; // from bootstrap node_module
#import "~bootstrap/scss/variables"; // from bootstrap node_module
So its looking for a node_modules/bootstrap folder,
npm install bootstrap
will add it.
when you run your gulp task and the sass starts compiling it needs the full bootstrap files located in node_modules/bootstrap/scss/ folder to compile correctly.
your "bootstrap-material-design.scss" will first import _core, _core will then import _variables, _variables imports a few custom files from another variables folder within the scss directory before looking at your node_modules folder (on line 56) with #import "~bootstrap/scss/functions";
your gulp task will pick up your sass files references (anything with an underscore is compiled at build time) - That spits out a plain css file where ever you set the destination to be eg "assets/css/style.css" which is the file you should reference in your html after build.
if this is still not happening for you you may just have a simple path issue to resolve. bootstrap versions can differ on sass fodler structure so double check your path in node_modules/bootstrap/scss/ actually has a functions folder.
If it does try #import "./node_modules/bootstrap/functions";
If it does not then you may need to check your version of bootstrap.
Eg - with bootstrap 4.1.1 they are imports not folders
#import '~bootstrap/scss/_functions';
#import '~bootstrap/scss/_variables';
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
Im following this tutorial to compile Sass with Gulp
https://www.youtube.com/watch?v=cg7lwX0u-U0
I think im doing the same as in the video but I get this error that I don't understand.
I don't want to compress it, I just want to compile all my .scss files to a single styles.css file, as I do with Compass.
You are using gulp-ruby-sass instead of the regular gulp-sass. gulp-ruby-sass does not use the gulp.src() command, instead you should give the path to it directly like this:
gulp.task('styles', function() {
sass('sass/_*.scss')
.pipe(gulp.dest('css/'));
});
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
http://sass-lang.com/documentation/file.SASS_REFERENCE.html#using_sass
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
