how to watch changes in whole directory/folder containing many sass files

问题

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.

回答1:

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 .:.

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

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.

回答5:

if you are in your current folder then do the following to watch it.

F:\sass tutorial>sass --watch ./:./

回答6:

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

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!
