Sass 3.2.1
How to replace in string some part of text? For example, remove from color #fefefe a dash #, to be fefefe.
Thanks!
Sass provides a collection of handy functions to manipulate strings, however there is no function to replace a substring with another string. Here is a quick str-replace function if you ever need one. .selector { content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
Sass String Functions The string functions are used to manipulate and get information about strings. Sass strings are 1-based. The first character in a string is at index 1, not 0.
Start the TRANWRD function. The TRANWRD function is a versatile function to replace one value with another. Specify the input variable that contains the character you want to replace. This input variable can be a column name, a string, or an expression. Specify the character that you want to replace.
Notice the extra space in the CSS (between a and day), which comes from the null value being converted to an empty string. While Sass provides only the single operator for strings, it does have a few built-in functions for manipulating strings. They might not appear useful at first, but they can be very useful when writing mixins and functions.
Here is a function that I just used!
SCSS-FUNCTION
/// Replace `$search` with `$replace` in `$string`
/// @author Hugo Giraudel
/// @param {String} $string - Initial string
/// @param {String} $search - Substring to replace
/// @param {String} $replace ('') - New value
/// @return {String} - Updated string
@function str-replace($string, $search, $replace: '') {
$index: str-index($string, $search);
@if $index {
@return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace);
}
@return $string;
}
SCSS-USAGE:
.selector {
$string: 'The answer to life the universe and everything is 42.';
content: str-replace($string, 'e', 'xoxo');
}
SCSS-RESULT:
.selector {
content: "Thxoxo answxoxor to lifxoxo thxoxo univxoxorsxoxo and xoxovxoxorything is 42.";
}

I use SASS with indented style, so this is my conversion to get a color variable to replace in a background with data:href inline encoded css svg-image. The # needs to be url-encoded and I use global colors that only needs to be replaced in one place and simply just work!
SASS-FUNCTION:
@function str-replace($string, $search, $replace: '')
$index: str-index($string, $search)
@if $index
@return str-slice($string, 1, $index - 1) + $replace + str-replace(str-slice($string, $index + str-length($search)), $search, $replace)
@return $string
SASS-USAGE:
$color-blue-night: #172b47
$icon-normal: str-replace('' + $color-blue-night, '#', '')
or for a clear example
.test
color: str-replace('' + $color-blue-night, '#', '')
SASS-RESULT:
.test {
color: "172b47"; }
