+    "screen-only": "only screen",
+    "xs-only": "only screen and (max-width: #{map-get($grid-breakpoints, "sm")-1})",


I think it is some ugly, more readable (with spaces):

#{map-get($grid-breakpoints, "sm") - 1}

Sure will make the changes

Can we add couple test more? the harder is the better

sure, I will try to add. Do you have anything in mind?

Something difficult with sass maps/list with interpolation

added new testcases

+  .text- #{ $name } {


I guess no. checked in the playground. Over there also it is formatting in the same way link

Let's add/fix two cases here in:

.text-#{ $name }

and

.text #{ $name }

sorry, didn't get your point. Can you please explain a bit.
.text-
#{ $name }
is formatting into
.text- #{ $name }

do you think it a bug? because we can't just assume that if it ends with "-", we have to merge the next text without space. The class name can also be just "test-", right?

No, it is not bug, just put in tests:

@each $size in $sizes { .icon #{$size} { border : "#{$size + "px"}" solid red; } }

and

@each $size in $sizes { .icon-#{$size} { border : "#{$size + "px"}" solid red; } }

and

//map test $font-weights : ("regular": 400 , "medium": 500, "bold": 700); @each $name, $boldness in $icons { .text #{ $name } { color: red; font-weight: "#{$boldness}" } }

//map test $font-weights : ("regular": 400 , "medium": 500, "bold": 700); @each $name, $boldness in $icons { .text-#{ $name } { color: red; font-weight: "#{$boldness}" } }

Instead

Thanks, will make the changes

Not sure it is safe to trim here, why we do it?

Stringify was adding extra '\n', so I am using trim

.icon-#{$size} above didn't add space around

@fisker and should not, you can write it in different ways (all valid):

.text foo { } .text- foo {} .text-foo {}

I mean space inside #{}, this one has space around $name, but .icon-#{$size} don't.

Yep, you are right

/cc @agamkrbit

I well make the changes ..
so .icon-#{$size} should be like .icon-#{ $size } right ?

Looks like we are keeping spaces on stable version.

Prettier 2.1.2

--parser scss

Input:

#{$a } { color: red; } #{ $a} { color: red; } #{ $a } { color: red; } #{$a} { color: red; }

Output:

#{$a } { color: red; } #{ $a} { color: red; } #{ $a } { color: red; } #{$a} { color: red; }

I have a question #9224 (comment)

fisker · 2020-09-23T04:30:23Z

@evilebottnawi

Do you think we should fix this by a solution fix both this and #9224?
It's more like "interpolation inside quoted string".

Update:

Found a old issue #2734, it seems already fixed by the parser shellscape/postcss-values-parser#37, unfortunately we are still using a old version.

alexander-akait · 2020-09-23T10:51:45Z

@fisker I think we can merge, I am afraid we can't update parser, because it is broken in many cases, also [email protected]/8.2 want to include built-in parser for selectors and values, maybe better to wait it

Yes, for both

fisker · 2022-11-24T06:38:06Z

Looks like we forgot about this one.

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width.

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ? R : never; // Prettier 2.8.3 (First format) type Foo<T> = T extends (a) => a is infer R extends string ?

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{!

It should be ignored in Prettier like the other SCM folders. ##### Recognize `@satisfies` in Closure-style type casts ([#14262](prettier/prettier#14262) by [@fisker](https://github.com/fisker))  ```jsx // Input const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); // Prettier 2.8.3 const a = /** @Satisfies {Record<string, string>} */ { hello: 1337 }; const b = /** @type {Record<string, string>} */ ({ hello: 1337 }); // Prettier 2.8.4 const a = /** @Satisfies {Record<string, string>} */ ({hello: 1337}); const b = /** @type {Record<string, string>} */ ({hello: 1337}); ``` ##### Fix parens in inferred function return types with `extends` ([#14279](prettier/prettier#14279) by [@fisker](https://github.com/fisker))  ```ts // Input type Foo<T> = T extends ((a) => a is infer R extends string) ?

This updates printer-glimmer to allow block params with custom "else if"-like blocks.  ```hbs {{!

This causes params to break to a new line together and not be split across lines unless the length of params exceeds the print width. This also updates the else block wrapping to behave exactly the same as opening blocks.  ```hbs {{! Input }} {{#block param param param param param param param param param param as |blockParam|}} Hello {{else block param param param param param param param param param param as |blockParam|}} There {{/block}} {{!
