How to convert directory SASS/SCSS to CSS via comm

问题:

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.

回答1:

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
