import { finalizeSelector } from '../src/util/formatVariantSelector'
import { crosscheck } from './util/run'
Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`. However, when you use `:hover::file-selector-button` or `::file-selector-button:hover`, then there is a big difference. In the first place, you can hover over the full file input to apply changes to the `File selector button`. In the second scenario you have to hover over the `File selector button` itself to apply changes. You can think of it as function calls: - focus(hover(text-center)) What you would expect is something like this: `.focus\:hover\:text-center:hover:focus`, where `hover` is on the inside, and `focus` is on the outside. However in the current implementation this is implemented as `.focus\:hover\:text-cener:focus:hover` * add more variant tests for the new API * update parallel variants tests to make use of new API * implement core variants with new API * simplify/cleanup existing plugin utils We can get rid of this because we drastically simplified the new addVariant API. * add addVariant shorthand signature The current API looks like this: ```js addVariant('name', ({ format, wrap }) => { // Wrap in an atRule wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' })) // "Mutate" the selector, for example prepend `.dark` format('.dark &') }) ``` It is also pretty common to have this: ```js addVariant('name', ({ format }) => format('.dark &')) ``` So we simplified this to: ```js addVariant('name', '.dark &') ``` It is also pretty common to have this: ```js addVariant('name', ({ wrap }) => wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' }))) ``` So we simplified this to: ```js addVariant('name', '@media (prefers-reduced-motion: reduce)') ``` * improve fontVariantNumeric implementation We will use `@defaults`, so that only the resets are injected for the utilities we actually use. * fix typo * allow for nested addVariant shorthand This will allow to write something like: ```js addVariant('name', ` @supports (hover: hover) { @media (print) { &:hover } } `) // Or as a one-liner addVariant('name', '@supports (hover: hover) { @media (print) { &:hover } }') ``` * update changelog

let selector = '.bg-\\[rgba\\(0\\,0\\,0\\)\\]'
let candidate = 'hover:bg-[rgba(0,0,0)]'
Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`. However, when you use `:hover::file-selector-button` or `::file-selector-button:hover`, then there is a big difference. In the first place, you can hover over the full file input to apply changes to the `File selector button`. In the second scenario you have to hover over the `File selector button` itself to apply changes. You can think of it as function calls: - focus(hover(text-center)) What you would expect is something like this: `.focus\:hover\:text-center:hover:focus`, where `hover` is on the inside, and `focus` is on the outside. However in the current implementation this is implemented as `.focus\:hover\:text-cener:focus:hover` * add more variant tests for the new API * update parallel variants tests to make use of new API * implement core variants with new API * simplify/cleanup existing plugin utils We can get rid of this because we drastically simplified the new addVariant API. * add addVariant shorthand signature The current API looks like this: ```js addVariant('name', ({ format, wrap }) => { // Wrap in an atRule wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' })) // "Mutate" the selector, for example prepend `.dark` format('.dark &') }) ``` It is also pretty common to have this: ```js addVariant('name', ({ format }) => format('.dark &')) ``` So we simplified this to: ```js addVariant('name', '.dark &') ``` It is also pretty common to have this: ```js addVariant('name', ({ wrap }) => wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' }))) ``` So we simplified this to: ```js addVariant('name', '@media (prefers-reduced-motion: reduce)') ``` * improve fontVariantNumeric implementation We will use `@defaults`, so that only the resets are injected for the utilities we actually use. * fix typo * allow for nested addVariant shorthand This will allow to write something like: ```js addVariant('name', ` @supports (hover: hover) { @media (print) { &:hover } } `) // Or as a one-liner addVariant('name', '@supports (hover: hover) { @media (print) { &:hover } }') ``` * update changelog

Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`. However, when you use `:hover::file-selector-button` or `::file-selector-button:hover`, then there is a big difference.

Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`.

The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`. However, when you use `:hover::file-selector-button` or `::file-selector-button:hover`, then there is a big difference. In the first place, you can hover over the full file input to apply changes to the `File selector button`. In the second scenario you have to hover over the `File selector button` itself to apply changes. You can think of it as function calls: - focus(hover(text-center)) What you would expect is something like this: `.focus\:hover\:text-center:hover:focus`, where `hover` is on the inside, and `focus` is on the outside. However in the current implementation this is implemented as `.focus\:hover\:text-cener:focus:hover` * add more variant tests for the new API * update parallel variants tests to make use of new API * implement core variants with new API * simplify/cleanup existing plugin utils We can get rid of this because we drastically simplified the new addVariant API. * add addVariant shorthand signature The current API looks like this: ```js addVariant('name', ({ format, wrap }) => { // Wrap in an atRule wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' })) // "Mutate" the selector, for example prepend `.dark` format('.dark &') }) ``` It is also pretty common to have this: ```js addVariant('name', ({ format }) => format('.dark &')) ``` So we simplified this to: ```js addVariant('name', '.dark &') ``` It is also pretty common to have this: ```js addVariant('name', ({ wrap }) => wrap(postcss.atRule({ name: 'media', params: '(prefers-reduced-motion: reduce)' }))) ``` So we simplified this to: ```js addVariant('name', '@media (prefers-reduced-motion: reduce)') ``` * improve fontVariantNumeric implementation We will use `@defaults`, so that only the resets are injected for the utilities we actually use. * fix typo * allow for nested addVariant shorthand This will allow to write something like: ```js addVariant('name', ` @supports (hover: hover) { @media (print) { &:hover } } `) // Or as a one-liner addVariant('name', '@supports (hover: hover) { @media (print) { &:hover } }') ``` * update changelog

Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible.

Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`.

Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this.

The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions.

Improve `addVariant` API (#5809) * fix incorrect comment Probably messed this up in another PR, so just a bit of cleaning. * implement a formatVariantSelector function This will be used to eventually simplify the addVariant API. The idea is that it can take a list of strings that define a certain format. Then it squashes everything to a single format how you would expect it. E.g.: Input: - '&:hover' - '&:focus' - '.dark &' - ':merge(.group):hover &' - ':merge(.group):focus &' Output: - ':merge(.group):focus:hover .dark &:focus:hover' The API here is: - `&`, this means "The parent" or "The previous selector" (you can think of it like if you are using nested selectors) - `:merge(.group)`, this means insert a `.group` if it doesn't exist yet, but if it does exist already, then merge the new value with the old value. This allows us to merge group-focus, group-hover into a single `.group:focus:hover ...` * add new `format`, `withRule` and `wrap` API for addVariant * implement backwards compatibility This will ensure that the backwards compatibility for `modifySelectors` and direct mutations to the `container` will still work. We will try to capture the changes made to the `rule.selector`, we will also "backup" the existing selector. This allows us to diff the old and new selectors and determine what actually happened. Once we know this, we can restore the selector to the "old" selector and add the diffed string e.g.: `.foo &`, to the `collectedFormats` as if you called `format()` directly. This is a bunch of extra work, but it allows us to be backwards compatible. In the future we could also warn if you are using `modifySelectors`, but it is going to be a little bit tricky, because usually that's implemented by plugin authors and therefore you don't have direct control over this. Maybe we can figure out the plugin this is used in and change the warning somehow? * fix incorrect test This was clearly a bug, keyframes should not include escaped variants at all. The reason this is here in the first place is because the nodes in a keyframe are also "rule" nodes. * swap the order of pseudo states The current implementation had a strange side effect, that resulted in incorrect class definitions. When you are combining the `:hover` and `:focus` event, then there is no difference between `:hover:focus` and `:focus:hover`. However, when you use `:hover::file-selector-button` or `::file-selector-button:hover`, then there is a big difference. In the first place, you can hover over the full file input to apply changes to the `File selector button`. In the second scenario you have to hover over the `File selector button` itself to apply changes.
