sass-embedded-linux-musl-x64

• Fix a crash that could come up with importers in certain contexts.

• Don't throw errors for at-rules in keyframe blocks.

• Throw errors for misplaced statements in keyframe blocks.

• Mixins and functions whose names begin with -- are now deprecated for forwards-compatibility with the in-progress CSS functions and mixins spec. This deprecation is named css-function-mixin.

• Fix a bug in which stylesheet canonicalization could be cached incorrectly when custom importers or the Node.js package importer made decisions based on the URL of the containing stylesheet.

JS API

• Allow importer to be passed without url in StringOptionsWithImporter.

• No user-visible changes.

• Support adjacent /s without whitespace in between when parsing plain CSS expressions.

• Allow the Node.js pkg: importer to load Sass stylesheets for package.json exports field entries without extensions.

• When printing suggestions for variables, use underscores in variable names when the original usage used underscores.

JavaScript API

• Properly resolve pkg: imports with the Node.js package importer when arguments are passed to the JavaScript process.

Command-Line Interface

• Ship the musl Linux release with the proper Dart executable.

JavaScript API

• Export the NodePackageImporter class in ESM mode.

• Allow NodePackageImporter to locate a default directory even when the entrypoint is an ESM module.

Dart API

• Make passing a null argument to NodePackageImporter() a static error rather than just a runtime error.

Embedded Sass

• In the JS Embedded Host, properly install the musl Linux embedded compiler when running on musl Linux.

For more information about pkg: importers, see the announcement on the Sass blog.

Command-Line Interface

• Add a --pkg-importer flag to enable built-in pkg: importers. Currently this only supports the Node.js package resolution algorithm, via --pkg-importer=node. For example, @use "pkg:bootstrap" will load node_modules/bootstrap/scss/bootstrap.scss.

JavaScript API

• Add a NodePackageImporter importer that can be passed to the importers option. This loads files using the pkg: URL scheme according to the Node.js package resolution algorithm. For example, @use "pkg:bootstrap" will load node_modules/bootstrap/scss/bootstrap.scss. The constructor takes a single optional argument, which indicates the base directory to use when locating node_modules directories. It defaults to path.dirname(require.main.filename).

Dart API

• Add a NodePackageImporter importer that can be passed to the importers option. This loads files using the pkg: URL scheme according to the Node.js package resolution algorithm. For example, @use "pkg:bootstrap" will load node_modules/bootstrap/scss/bootstrap.scss. The constructor takes a single argument, which indicates the base directory to use when locating node_modules directories.

JavaScript API

• Add a sass.initCompiler() function that returns a sass.Compiler object which supports compile() and compileString() methods with the same API as the global Sass object. On the Node.js embedded host, each sass.Compiler object uses a single long-lived subprocess, making compiling multiple stylesheets much more efficient.

• Add a sass.initAsyncCompiler() function that returns a sass.AsyncCompiler object which supports compileAsync() and compileStringAsync() methods with the same API as the global Sass object. On the Node.js embedded host, each sass.AsynCompiler object uses a single long-lived subprocess, making compiling multiple stylesheets much more efficient.

Embedded Sass

• Support the CompileRequest.silent field. This allows compilations with no logging to avoid unnecessary request/response cycles.

• The Dart Sass embedded compiler now reports its name as "dart-sass" rather than "Dart Sass", to match the JS API's info field.

Embedded Sass

• In the JS Embedded Host, properly install the x64 Dart Sass executable on ARM64 Windows.

• Produce better output for numbers with complex units in meta.inspect() and debugging messages.

• Escape U+007F DELETE when serializing strings.

• When generating CSS error messages to display in-browser, escape all code points that aren't in the US-ASCII region. Previously only code points U+0100 LATIN CAPITAL LETTER A WITH MACRON were escaped.

• Provide official releases for musl LibC and for Android.

• Don't crash when running meta.apply() in asynchronous mode.

JS API

• Fix a bug where certain exceptions could produce SourceSpans that didn't follow the documented SourceSpan API.
