* Temporarily move postcss to dependencies
This is unfortunate but upgrading postcss-js caused postcss to not be installed at all. This is fine except in this case of NPM <= 6 when running npx tailwindcss init, or yarn v1, or npm 7/8 with legacy peer deps behavior and doing a similar thing. Deduping will still allow the user to install postcss and upgrade it and Tailwind CSS will pick it up. A more permanent solution may involve hijacking require or something similar.
* Update changelog
* add prettier-plugin-tailwindcss
This will use the prettier plugin in our tests as well, yay consistency!
* ensure that both `group` and `peer` can't be used in `@apply`
This was only configured for `group`
* expose `sortClassList` on the context
This function will be used by the `prettier-plugin-tailwindcss` plugin,
this way the sorting happens within Tailwind CSS itself adn the
`prettier-plugin-tailwindcss` plugin doesn't have to use internal /
private APIs.
The signature looks like this:
```ts
function sortClassList(classes: string[]): string[]
```
E.g.:
```js
let sortedClasses = context.sortClassList(['p-1', 'm-1', 'container'])
```
* update changelog
* add sort test for utilities with the important modifier e.g.: `!p-4`
* Add failing tests for negative utility detection
We're not generating them properly in all cases, when using at-apply we sometimes crash, and safelisting doesn't currently work as expected.
* Refactor
* Generate utilities for negatives before and after the prefix
* Properly detect negative utilities with prefixes in the safelist
* Refactor test a bit
* Add class list tests
* Update changelog
* quick fix for incorrect arbitrary properties
Turns out that using links like [https://example.com] causes arbitrary
properties to generate invalid css.
This is a very dirty quick fix for this specific case, so we have to fix
this properly!
* update changelog
* ensure content files are available in config
If you use the cli with the `--content` option, then we first resolve
the config (empty), then add the `content` to the config. The issue is
that this means that the content will be empty when you resolve it
initially. This results in a warning in your terminal.
Now, we will make sure to merge 2 configs if you have the `--content`
data passed. We will also make sure to override the final
`config.content.files` to whatever you passed in to make sure that this
is the same behaviour as before.
* update changelog
* ensure that we compile the postcss nesting plugin
* re-add optional chaining
This will allow us to be 100% sure that we can safely call
hasOwnProperty in case we get some very strange objects.
This will now also be compiled/transpiled by esbuild.
* import the internal postcss nesting plugin
This allows us to work on it without re-compiling while running tests.
Just like we do with all other code.
* update changelog
* remove optional chaining
This breaks on Node versions lower than version 13. Normally we
transpile everything, but we currently don't do this for the nesting
plugin since it is not really part of the `src` folder.
Will get this fixed in a better way, but for now this is a quick fix to
get everything working again!
