## Summary
Slang is basically a Slim template language for Crystal language, so the
very same Slim parser works fine.
Slim template: https://github.com/slim-template/slim
Slang template: https://github.com/jeromegn/slang
## Test plan
Create a simple slang file with some tailwind-css and check if the CSS
is being extracted:
```slim
doctype html
html
head
title This is a title
body.min-h-screen
header.stick.top-0.z-10
section.max-w-4xl.mx-auto.p-4.flex.items-center.justify-between
h1.text-3xl.font-medium This is a slang file
```
To test it, get any slim template, rename the extension to .slang
Fixes#17851

Fixes#18431
The `~W(…)` syntax in Elixir is a _sigil_. It's basically another way to
write strings, arrays of strings, etc… The syntax lets you use a handful
of surrounding brackets like `~W(…)`, `~W[…]`, `~W{…}`, `~W"…"`, etc… to
let you write lists without necessarily having to escape characters.
In v3 our extractor was able to pick these up but in v4 Oxide does not.
I've added a preprocessor for Elixir files so we can modify the code
before our main extractor sees it.
Now things like this: `~W(text-white bg-gray-600)` will get turned into
` ~W text-white bg-gray-600 ` which can easily be processed by our
extractor.
The sigils we support are:
- `~s` / `~S` (strings)
- `~w` / `~W` (word lists)
- `~c` / `~C` (charlists)
We're specifically detecting the use of `(…)`, `[…]`, and `{…}` as using
quotes already works today.

## Summary
In a form like,
```clojure
(if condition :bg-white :bg-black)
```
`:bg-black` will fail to extract, while `:bg-white` is extracted as
expected. This PR fixes this case, implements more comprehensive
candidate filtering, and supersedes a previous PR.
Having recently submitted a PR for handling another special case with
Clojure keywords (the presence of `:` inside of keywords), I thought it
best to invert the previous strategy: Instead of handling special cases
one by one, consume keywords according to the Clojure reader spec.
Consume nothing else, other than strings.
Because of this, this PR is a tad more invasive rather than additive,
for which I apologize. The strategy is this:
- Strings begin with a `"` and ends with an unescaped `"`. Consume
everything between these delimiters (existing case).
- Keywords begin with `:`, and end with whitespace, or one out of a
small set of specific reserved characters. Everything else is a valid
character in a keyword. Consume everything between these delimiters, and
apply the class splitting previously contained in the outer loop. My
previous special case handling of `:` inside of keywords in #18338 is
now redundant (and is removed), as this is a more general solution.
- Discard _everything else_.
I'm hoping that a strategy that is based on Clojure's definition of
strings and keywords will pre-empt any further issues with edge cases.
Closes#18344.
## Test plan
- Added failing tests.
- `cargo test` -> failure
- Added fix
- `cargo test` -> success

## Summary
Taking a shot at fixing my own complaint from #18336.
Added failing test and fix for extracting classes containing a
pseudo-class from Clojure keywords. Eg., `:hover:text` ->
`"hover:text"`. This would previously produce `["hover", "text"]`.
## Test plan
- Add a failing test.
- Verify that it fails with `cargo test`.
- Add fix.
- Verify that `cargo test` has no further complaints.

This PR fixes a Haml pre-processing issue where a crash occurs if there
is no trailing `\n` at the end of the file and the code before it was
considered Ruby code.
This happens in situations where Ruby code was used. E.g.:
```
- index = 0
- index += 1
```
In this situation when we see the `-` on the second line, then we will
find the whole indented block and parse it as Ruby code instead. The
block ands at the last `\n`, but since we reach the end of the file,
there is no `\n`. Right now we incorrectly reset the internal cursor to
the last known `\n` position. This means that the `start` of the Ruby
block will be _after_ the `end` of the Ruby block and the Haml parser
will crash.
To solve this, once we reach the end of the file, we don't reset the
cursor to the wrong position.
Fixes:

## Test plan
1. Added a regression test that did fail before the fix, and doesn't
anymore

This PR fixes an issue in the Clojure pre-processor where candidates
including `.` characters were not extracted correctly.
The solution here is to only replace the `.` with a ` ` when the `.` is
not surrounded by numbers. This means that:
```
:.foo.bar
```
Becomes
```
: foo bar
```
But
```
:.gap-1.5.flex
```
Becomes
```
: gap-1.5 flex
```
This way the `gap-1.5` is correctly extracted.
## Test plan
1. Added a test for this case
2. Tested this in the extractor tool as well. Notice how the `gap-1.5`
is correctly extracted here.

Fixes: 17760
This PR fixes a bug where a class like `header_1` wasn't properly
extracted because we didn't allow an `_` before a number.
This PR fixes that by allowing an `_` before a number.
Fixes: #17960
## Test plan
1. Added a test to verify this works
2. Existing tests work
Used the visualizer tool for this to verify that the `header_1` class is
being extracted:

Closes#15806
This PR adds a new `postinstall` script to `@tailwindcss/oxide` that
will attempt to download the platform-specific optional dependency to
avoid issues when the package manager does not do that automatically
(see #15806). The implementation for this is fairly simple: The npm
package is downloaded from the official npm servers and extracted into
the `node_modules` directory of the `@tailwidncss/oxide` installation.
## Test plan
Since we still lack a solid repro of #15806, the way I tested this
change was to manually remove all automatically-installed optional
dependencies and then running the postinstall script manually. The
script then downloads the right version package which makes the import
to `@tailwidncss/oxide` work. An appropriate integration test was added
too.
I furthermore also validated that:
- This works across CI platforms [ci-all]
- The postinstall script bails out when running `pnpm install` in the
dev setup. This is necessary since doing the initial install won't have
any binary dependencies yet so it would download invalid versions from
npm (as the version numbers locally refer to the last released version).
We can safely bail out here though since this was never an issue with
local development.
- The postinstall script does not do anything when the
`@tailwindcss/oxide` library is added _unless_ the issue is detected.

Closes#15452
This PR adds more directories to the list of ignored content dirs. These
are now handled the same as `node_modules`:
- Contents of this directory are ignored by default to avoid scanning
dependency trees
- Explicit `@import`s inside these folders are now treated as
_external_, bypassing any `.gitignore` files.
The new extensions are:
- Version control systems: `.hg`, `.svn`
- Bundler caches: `.venv`, `venv`, `.yarn`
- Framework caches: `.next`, `.turbo`, `.parcel-cache`, `__pycache__`,
`.svelte-kit`
## Test plan
Verified with the repro of #15452 by renaming the ignored directory to
`.venv` and installing a local tarball:

This PR improves the debugability of the scanner when using `DEBUG=*` by
writing to a `tailwindcss-{pid}.log` file in the current working
directory.
It will include all the tracing information from the scanner. This PR
also introduces `Discovering {path}` and `Reading {path}` logs.
- `Discovering {path}` — this is logged when we are traversing the file
system looking for files. We use the `ignore` crate, and log this
information in the `filter_entry` callback. If a file was already
ignored by `.gitignore` files, this won't show up, but it also means
that we will not read it.
- `Reading {path}` — this is when we are actually reading the file so we
can start extracting potential Tailwind CSS classes.
These will give you some insights in what paths are being scanned, and
if we get stuck, where we get stuck.
Also, we are appending to the file. In the log below, you can already
see that a `tailwindcss-<number>.log` file exists already even though it
didn't exist before running the command. This should make it easier to
debug if we get stuck on a specific file/folder because the file will be
populated with information.
There are a few reasons for appending to a file:
1. There is a lot of output, so spamming the stdout/stderr is not ideal
2. If you run the same command again, after changing your `@source`
directives, you could diff the outputs. (although, the timestamps will
be different)
3. When using `DEBUG=*`, a lot of other tools also output debug
information, so writing to a file should make this better.

We also output where we are writing the file to. This looks like this
when using the CLI:

src="https://github.com/user-attachments/assets/79c2cc95-adea-4bbd-a4f1-101de45726f5"
/>
Last but not least, this also ignores `.log` files by default
## Test plan
Ran the CLI (but you can use any tool real, since this is implemented in
Oxide) with the `DEBUG=*` flag.
The file generated, looks like the example I shared above.
This PR fixes a Windows CI issue due to the recently merged #17846
There might be better ways to solve this, but essentially we want to
make sure we are always dealing with `\n` and not `\r\n`. This PR fixes
that by replacing all `\r\n` with `\n` in the tests.
This PR fixes and improves the HAML extractor by ensuring that whenever
we detect lines or blocks of Ruby code (`-`, `=` and `~`) characters at
the beginning of the line, we treat them as Ruby code.
Fixes: #17813
## Test Plan
1. Existing tests pass
2. Changed 1 existing test which embedded Ruby syntax
3. Added a dedicated test to ensure the HAML file in the linked issue is
parsed correctly
Running this in the internal extractor tool you can see that the
`w-[12px]`, `w-[16px]`, `h-[12px]`, and `h-[16px]` are properly
extracted.
Note: the `mr-12px` is also extracted, but not highlighted because this
is not a valid Tailwind CSS class.

This PR ignores `.db` files by default. We already ignored `.sqlite` and
`.sqlite3` files but we didn't ignore `.db` files which is a common
extension for database files as well.
Due to the binary nature of `.db` files, scanning these could result in
hard to debug errors such as:
Resolves https://github.com/tailwindlabs/tailwindcss/issues/17699
GeoJSON files are giant JSON files for geographic data structures and
will never contain Tailwind classes, but because they are often huge
they will slow down the build a lot if scanned.

We generate a glob to ignore binary extensions that looks something like
this:
```
*.{mp4,pages,exe,…}
```
However, if you have a folder that happens to end in `.pages` for
example, then this folder will be ignored in its entirety.
To solve this, we added a new flag to the `Gitignore` struct so we can
register a bunch of ignore rules that _only_ apply to paths and not
folders.

Closes#17448Closes#13133
This PR adds an a new Oxide target for `wasm32-wasip1-threads`:
`@tailwindcss/oxide-wasm32-wasi`. The goal of this is to enable more
environments to run Oxide, including (but not limited to) StackBlitz.
We're making use of `napi-rs`'s upcoming v3 features to simplify the
setup here, meaning `napi-rs` will configure the WASM target and create
an npm package that works across Node and browser environments.
## MacOS AArch64 issues
While setting up an integration test for the new WASM target, I ran into
an issue where FS reads where not terminating on macOS. After some
research I found this to be a limitation of the Node.js container
interface right now, see: https://github.com/nodejs/node/issues/47193
### Windows issues
We also found that the Node.js wasi container does not properly support
Windows: https://github.com/nodejs/uvwasi/issues/11
For now we, it's probably best for MacOS AArch64 users and Windows users
to use the native modules instead.
## Test plan
The `@tailwindcss/oxide-wasm32-wasi` npm package can be built locally
via `pnpm build` and then run with the Oxide API. A usage example can be
taken from the newly added integration test.
Furthermore this was tested to work as a polyfill on StackBlitz:

This PR fixes an issue where the Ruby `%w[…]` syntax causes utilities to
not be properly extracted.
This PR will now ensure that it does get extracted correctly.
Given this input:
```slim
div[
class=%w[bg-blue-500 w-10 h-10]
]
div[
class=%w[w-10 bg-green-500 h-10]
]
```
Before this PR, we extracted everything but the `bg-blue-500`. The
`w-10` was extracted but not because of the second div, but because of
the first one.
Fixes: #17542
## Test plan
1. Added a test to ensure it's working correctly.
Looking at the extractor tool, you can see that it now gets extracted
correctly. Top is before, bottom is with this change.

This PR is a follow-up PR for:
https://github.com/tailwindlabs/tailwindcss/pull/17433
In the other PR we allow scanning CSS files for extracting usages of CSS
variables. This is important for `.module.css` files that reference
these variables but aren't in the same big AST of the main CSS file.
This PR also makes sure to watch for changes in those registered CSS
files and re-extract the variables when they change.
This PR took a bit longer than expected because I was trying to make
sure that writing to `./dist/out.css` works without infinite-looping
(e.g.: we had issues with this in Tailwind CSS v3 with webpack).
But I couldn't reproduce the issue at all. I did had some code that
tried to detect if the CSS file contained license headers and skip in
(because then it's very likely an output CSS file) but even without it
the tests were fine.
I setup integration tests with `@tailwindcss/cli` itself, and with tools
that use webpack. Added a test for Next.js, and a dedicated webpack test
as well.
Even without tests, locally, I couldn't reproduce an infinite loop due
to changes in an output CSS file...
Eventually dropped the code that tries to detect output CSS files.
One thing to keep in mind is that if you change any of your "main" CSS
files, then we will trigger a full rebuild anyway, so this change is
only required for unrelated CSS files (like CSS module files) that use
CSS variables.
## Test plan
1. Added integration tests for the CLI and Next.js
2. Added new dedicated test for webpack
This PR fixes an issue where CSS variables could be used in CSS modules,
but where never emitted in your final CSS.
Some backstory, when Tailwind CSS v4 came out, we _always_ emitted all
CSS variables whether they were used or not.
Later, we added an optimization where we only emit the CSS variables
that were actually used. The definition of "used" in this case is:
1. Used in your CSS file(s) — (we check the final CSS AST for this)
2. Used _somewhere_ in any of your source files (e.g.: a JavaScript file
accessing a variable)
The issue this PR tries to solve is with the very first point. If you
are using CSS modules, then every CSS file is processed separately. This
is not a choice Tailwind CSS made, but how other build tooling works
(like Vite for example).
To prevent emitting all of Tailwind's Preflight reset and all utilities
per CSS file, you can use the `@reference` directive instead of
repeating `@import "tailwindcss";`. This is explained here:
https://tailwindcss.com/docs/compatibility#explicit-context-sharing
But now we are just _referencing_ them, not emitting them. And since the
CSS module is not connected in any way to the main `index.css` file that
contains the `@import "tailwindcss";` directive, we don't even see the
CSS variables while processing the `index.css` file. (or wherever your
main CSS file is)
This is where point 2 from above comes in. This is a situation where we
rely on the extractor to find the used CSS variables so we can
internally mark them as used.
To finally get to the point of this PR, the extractor only scans
`.html`, `.js`, ... files but not `.css` files. So all the CSS variables
used inside of CSS modules will not be generated.
This PR changes that behavior to also scan `.css` files. But _only_ for
CSS variables (not any other type of class candidate). This is
important, otherwise all your custom `@utility foo {}` definitions would
always mark `foo` as a used class and include it in the CSS which is not
always the case.
On top extracting CSS variables, we will also make sure that the CSS
variables we find are in usage positions (e.g.: `var(--color-red-500)`)
and not in definition positions (e.g.: `--color-red-500: #ff0000;`).
This is important because we only want to emit the variables that are
actually used in the final CSS output.
One future improvement not implemented here, is that technically we will
also extract CSS variables that might not be used if defined in a
`@utility`.
```css
@utility never-used {
color: var(--color-red-500); /* --color-red-500 will be emitted, even if it might not be used */
}
```
Fixes: #16904Fixes: #17429
# Test plan
1. Added a test where CSS variables are defined in `.css` files (and
ignored)
2. Added a test where CSS variables are used in `.css` files (and
included)
Testing on the reproduction defined in #16904, the `.module.css` file
contains a reference to `var(--color-hot-pink)`, but generating a build
shows that the variable definition is not available:
<img width="1630" alt="image"
src="https://github.com/user-attachments/assets/a0d5c37e-6813-4cd5-a677-6c356b5a73d4"
/>
When you run the build again with the changes from this PR, then we _do_
see the definition of the `--color-hot-pink` in the root CSS file:
<img width="2876" alt="image"
src="https://github.com/user-attachments/assets/beab7c11-a31b-4ea4-8235-4849a8e92859"

This PR fixes an extraction issue in Razor files where `@@md:bg-red-500`
can't always be extracted properly. We already convert `@@md:bg-red-500`
to ` @md:bg-red-500` but in certain situations Razor will emit the
double `@@` to the DOM.
A workaround in Razor land would be to write `@("@")md:bg-red-500`
instead. See: https://github.com/dotnet/aspnetcore/issues/38595 But then
we don't extract the `@md:bg-red-500` properly anymore.
This is where this PR comes in, essentially we will pre process the
Razor contents and apply the following replacement internally:
```diff
- @("@")md:bg-red-500
+ @md:bg-red-500
```
Notice that the `)` looks like it's replaced with `@`. This will have a
small side effect later when we get to the testing part.
But this way we properly see the `@md:bg-red-500` class during class
extraction.
> [!WARNING]
> There is technically a bug here because of the replacement with `@`,
because if you now run the `npx @tailwindcss/upgrade@latest` tool, then
we would replace `)md:bg-red-500` if changes are required, not the
`@("@")md:bg-red-500` part. We can try to fix that in this PR but it
seems unlikely that we will actually run into this issue realistically
speaking. I think fixing the actual extraction here is much more
important than the upgrade tooling that could fail _if_ we ever have to
migrate `@md:…` to something else.
Fixes: #17424
## Test plan
1. Added a test to verify the fix
2. Existing tests pass
3. Verified this in the extractor tool, but it looks a tiny bit funky.
Typically we remove characters by replacing it with a space ` `. But
this time, we replace it with some spaces _and_ an `@` character that
didn't exist at that specific position. If you look at the diff above,
you will notice that `)` was replaced with `@`.
That's why in the extractor tool it is highlighted that it could extract
it, but it's just funny looking because it highlights `)md:bg-red-500`

Was working on another issue and noticed that I wanted these but they
aren't related to any of the issues. So opening a separate PR to do some
internal cleanup.
This PR fixes some issues related to symlinks when using them in the
`@source` directive.
Fixes: #16765Fixes: #16038
## Test plan
1. Added tests to prove this works
- Added a recursive symlink test as well to make sure we don't hang
2. Existing tests still pass
