# operator-no-newline-after
|
|
|
|
Disallow linebreaks after Sass operators.
|
|
|
|
```scss
|
|
a { width: 10px + $n; }
|
|
/** ↑
|
|
* Linebreaks after this */
|
|
```
|
|
|
|
This rule checks math operators (`+`, `-`, `/`, `*`, `%`) and comparison operators (`>`, `<`, `!=`, `==`, `>=`, `<=`).
|
|
|
|
Not all symbols that correspond to math operators are actually considered operators by Sass. Some of the exceptions are:
|
|
|
|
* `+` and `-` as signs before values;
|
|
* `+` and `-` as signs in [space-delimited lists](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#string_operations);
|
|
* `-` as part of [a string](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#string_operations) or [a Sass identifier](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#subtraction), e.g. a variable;
|
|
* `/` as a CSS delimiter in property values like `font: 10px/1.2 Arial;` ([read more](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#division-and-slash)).
|
|
|
|
For more details refer to [Sass official documentation](http://sass-lang.com/documentation/file.SASS_REFERENCE.html). An online Sass compiler - [Sassmeister](http://www.sassmeister.com/) - could also come in handy.
|
|
|
|
The following patterns are considered warnings:
|
|
|
|
```scss
|
|
a { width: 10 +
|
|
1; }
|
|
```
|
|
|
|
```scss
|
|
a {
|
|
width: 10 +
|
|
1;
|
|
}
|
|
```
|
|
|
|
The following patterns are *not* considered warnings:
|
|
|
|
```scss
|
|
a {
|
|
width: str- // not a math operator, ignored
|
|
some;
|
|
}
|
|
```
|
|
|
|
```scss
|
|
a { width: 10px - 1; }
|
|
```
|
|
|
|
```scss
|
|
a {
|
|
width: 10px * 1.7 // the newline is not right after the operator
|
|
+ 1;
|
|
}
|
|
```
