# at-else-empty-line-before
|
|
|
|
Require an empty line or disallow empty lines before `@`-else.
|
|
|
|
```scss
|
|
@if ($a == 0) { }
|
|
/* ← */
|
|
@else if ($x == 2) { } ↑
|
|
↑
|
|
/** ↑
|
|
* This empty line */
|
|
```
|
|
|
|
`@if` and `@else` statements might need to have different behavior than all the other at-rules. For that you might need to set `"ignoreAtRules": ["else"]` for stylelint's core rule [`at-rule-empty-line-before`](http://stylelint.io/user-guide/rules/at-rule-empty-line-before/). But that would make you unable to disallow empty lines before `@else` while forcing it to be on a new line. This rule is designed to solve exactly that.
|
|
|
|
## Options
|
|
|
|
`string`: `"never"`
|
|
|
|
There is no `"always"`, `"always-single-line"` options, because for such cases stylelint's `at-rule-empty-line-before` would work.
|
|
|
|
### `"never"`
|
|
|
|
There *must never* be an empty line before `@else` statements.
|
|
|
|
The following patterns are considered warnings:
|
|
|
|
```scss
|
|
@if ($x == 1) {
|
|
// ...
|
|
}
|
|
|
|
@else {}
|
|
```
|
|
```scss
|
|
@if ($x == 1) {
|
|
// ...
|
|
} @else if ($x == 2) {
|
|
// ...
|
|
}
|
|
|
|
|
|
@else { }
|
|
```
|
|
|
|
The following patterns are *not* considered warnings:
|
|
|
|
```scss
|
|
@if ($x == 1) {
|
|
// ...
|
|
} @else if ($x == 2) {
|
|
// ...
|
|
} @else {}
|
|
|
|
a {
|
|
@if ($x == 1) {
|
|
// ...
|
|
}
|
|
@else ($x == 2) {
|
|
// ...
|
|
}
|
|
}
|
|
```
