I'm creating some icon font rules for using in my site. Using Sass I wanted to list all the icons in a list variable and use #each to loop through them all.
Code looks like this:
$icons:
wifi 600,
wifi-hotspot 601,
weather 602;
#each $icon in $icons {
.icon-#{nth($icon, 1)},
%icon-#{nth($icon, 1)} {
content: "\#{nth($icon, 2)}";
}
}
The problem is the backslash on the content: line. I need it for the character encoding, but it escapes the variable interpolation, outputting CSS that looks like this:
.icon-wifi {
content: "\#{nth($icon, 2)}";
}
Adding one more backslash like this: content: "\\#{nth($icon, 2)}"; outputs this CSS:
.icon-wifi {
content: "\\600";
}
Is there a way to get the Sass to output CSS with only a single backslash while keeping the variable interpolation?
I got this to work by messing with the interpolation
sassmesiter demo
// ----
// Sass (v3.4.21)
// Compass (v1.0.3)
// ----
$icons:
wifi 600,
wifi-hotspot 601,
weather 602;
#each $icon in $icons {
.icon-#{nth($icon, 1)},
%icon-#{nth($icon, 1)} {
content: #{'"\\' + nth($icon, 2) + '"'}; // <------ See this line
}
}
compiles to
.icon-wifi {
content: "\600";
}
.icon-wifi-hotspot {
content: "\601";
}
.icon-weather {
content: "\602";
}
If you include the backslash in the actual variable, then when the sass generates the css, it will actually generate the calculated unicode character instead of outputting the unicode in the css output. This still usually works but it's hard to debug if something is going wrong and it is a bit more prone to cause issues in the browser in rendering the icon.
To output the actual unicode in the generated CSS, you can do this:
#function icon($character){
#return unquote('\"') + unquote(str-insert($character,'\\', 1)) + unquote('\"');
}
$icon-thing: "e60f";
.icon-thing:before {
content: icon($icon-thing); //outputs content: "\e60f";
}
You can add the backslash to the parameter in the $icons variable. That is,
$icons: wifi "\600", wifi-hotspot "\601", weather "\602";
#each $icon in $icons {
.icon-#{nth($icon, 1)}, %icon-#{nth($icon, 1)} {
content: "#{nth($icon, 2)}";
}
}
Generated CSS:
.icon-wifi {
content: "\600";
}
.icon-wifi-hotspot {
content: "\601";
}
.icon-weather {
content: "\602";
}
Use unquote and double slash
$var:123 → content:"\e123"
content:#{unquote('\"')+("\\")+("e")+$var+unquote('\"')};
If you are using Gulp to compile your Sass files, installing this Gulp plugin is probably the easiest way to get around the issue:
https://www.npmjs.com/package/gulp-sass-unicode
var sass = require('gulp-sass');
var sassUnicode = require('gulp-sass-unicode');
gulp.task('sass', function(){
gulp.src('style.scss')
.pipe(sass())
.pipe(sassUnicode()) // <-- This is the bit that does the magic
.pipe(gulp.dest( "css/" ));
});
There is no need to make any code alterations in your Sass files. Write out your Sass code how you want and the unicode characters are decoded back into regular escaped strings in the output CSS automatically.
Input SCSS
$testContent: "\f26e";
#test {
content: $testContent;
}
Output CSS
#test {
content: "\f26e";
}
Unfortunately, these solutions were not entirely working for me but I was finally able to get it working with SASS maps
//node-sass 4.11.0
//libsass 3.5.4
$hexes: (
checkmark: \2714
);
#function out-content($var) {
#return unquote("\"#{ $var }\"");
}
#each $mod, $code in $hexes {
.#{$mod}-after {
&:after {
content: out-content($code);
}
}
}
//output
//.checkmark-after:after {
//content: "\2714";
//}

I have this:
.a-btn {
//rules here
##{&}__label {
//more rules
}
}
so I am after such an output:
.a-btn {…}
#a-btn__label {…}
BUT That compiles to this error:
SassError: Invalid CSS after "#": expected selector, was "#.a-btn"
So I need to convert .a.btn to a-btn. Therefore I have tried to use str-slice like that:
.a-btn {
//rules here
##{str-slice(&, 2)}__label {
//more rules
}
}
But that yields:
SassError: argument `$string` of `str-slice($string, $start-at, $end-at:-1)` must be a string
Can you try this
.a-btn
#at-root ##{str-slice(#{&},2)}__label
height: 200px
width: 200px
background: red
file a.scss:
$myVariable:#ffffff;
file b.scss:
#import './a.scss';
//does not work
:root{
--root-variable:$myVariable;
}
//works
.myClass{
color:$myVariable;
}
The editor sees the value of myVariable in the b.scss file. But after compiling on the page, if you look at the properties, it looks like this:
--root-variable:$myVariable
but expected:
--root-variable:#ffffff
webpack:
{
test: /\.vue$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'vue-loader',
options: {
loaders: {
scss: 'vue-style-loader!css-loader!sass-loader', // <style lang="scss">
sass: 'vue-style-loader!css-loader!sass-loader?indentedSyntax' // <style lang="sass">
}
}
}
}
How to fix it?
//UPDATE
I changed the question because I found the problem, but I still do not know how to solve it
For anyone coming across this now, it was due to a change in Sass 3.5, which is explained here.
Using Sass variables when defining custom CSS variables now needs to be done slightly differently. This used to work:
:root {
--root-variable: $myVariable;
}
But now you should now do this:
:root {
--root-variable: #{$myVariable};
}
I'm using CodeKit to compile .scss using libsass. In these files I want to include some Liquid templating
.some-class {
color: {{ settings.color_primary }};
}
Throws and error though. Is there a way to tell the preprocessor to let this pass through?
Thanks
Use sass interpolations to insert anything literally
.some-class {
color: #{ "{{ settings.color_primary }}" };
}
You may also use a helper function for nicer syntax
#function liquid-var($name) {
#return #{ "{{ " + $name + " }}" };
}
.some-class {
color: liquid-var("settings.color_primary");
}
I have written below code in sass / scss. Here i am facing an issue i.e. when i'm trying to loop and concatenate value with \ . I'm getting space when my value contains alpha numeric. Kindly suggest how to overcome form this
SCSS =>>
Input :
$data: (
a:2766,
b:27B3,
d:1F48C
);
#each $value1, $value2 in $data {
.#{$value1}{
content: str-slice("\x",1,1)+($value2);
}
}
Output :
.a {
content: "\2766";
}
.b {
content: "\27B 3";
}
.d {
content: "\1F 48C";
}
It looks like this is a bug in Sass itself. Update your Sass and your problem should be fixed.
You can see this is the case on sass playground. Copy and paste your sass code there and then select Sass v3.3.14 and Sass v3.4.21 (or any later/newer) and you'll see the difference. :)
Edit:
In order to add \x at the beginning, you can do it this way:
SCSS (Sass v3.4.21):
$data: (
a: 2766,
b: 27B3,
d: 1F48C
);
#each $value1, $value2 in $data {
.#{$value1}{
content: str-insert(#{$value2}, "\\x", 1);
}
}
CSS output:
.a {
content: \x2766;
}
.b {
content: \x27B3;
}
.d {
content: \x1F48C;
}
str-insert puts a string inside other string. \\ in \\x escapes to single \x. Oh, and as the reference states, first character in sass is 1, not 0.
I have this snippet of code in my scss file:
$ttk-bg-green: #99FF00;
$ttk-bg-orange: #FFBE00;
$ttk-bg-purple: #CD66FF;
$ttk-bg-blue: #55BBFF;
$ttk-icon-green: #80D500;
$ttk-icon-orange: #FFAF37;
$ttk-icon-purple: #CD66FF;
$ttk-icon-blue: #62C0FF;
$color-types: "bg" "icon";
$color-styles: "green" "orange" "purple" "blue";
#each $color-type in $color-types {
#each $color-style in $color-styles {
.ttk-#{$color-type}-#{$color-style} { color: $ttk-#{$color-type}-#{$color-style}; }
}
}
it's supposed to generate something along the lines of:
.ttk-bg-green: #99FF00;
The compass compiler fails to compile the code, saying $ttk variable does not exist.
it just fails to recognize it as a whole variable.
ideas? solutions?
