dart-sass/CHANGELOG.md

1.2.1

• Always emit units in compressed mode for 0 dimensions other than lengths and angles.

1.2.0

• The command-line executable will now create the directory for the resulting CSS if that directory doesn't exist.

• Properly parse #{$var} -#{$var} as two separate values in a list rather than one value being subtracted from another.

• Improve the error message for extending compound selectors.

1.1.1

• Add a commit that was accidentally left out of 1.1.0.

1.1.0

• The command-line executable can now be used to write an output file to disk using sass input.scss output.css.

• Use a POSIX-shell-compatible means of finding the location of the sass shell script.

1.0.0

Initial stable release.

Changes Since 1.0.0-rc.1

• Allow ! in custom property values (#260).

Dart API

• Remove the deprecated render() function.

Node API

• Errors are now subtypes of the Error type.

• Allow both the data and file options to be passed to render() and renderSync() at once. The data option will be used as the contents of the stylesheet, and the file option will be used as the path for error reporting and relative imports. This matches Node Sass's behavior.

1.0.0-rc.1

• Add support for importing an _index.scss or _index.sass file when importing a directory.

• Add a --load-path command-line option (alias -I) for passing additional paths to search for Sass files to import.

• Add a --quiet command-line option (alias -q) for silencing warnings.

• Add an --indented command-line option for using the indented syntax with a stylesheet from standard input.

• Don't merge the media queries not type and (feature). We had previously been generating not type and (feature), but that's not actually the intersection of the two queries.

• Don't crash on $x % 0.

• The standalone executable distributed on GitHub is now named sass rather than dart-sass. The dart-sass executable will remain, with a deprecation message, until 1.0.0 is released.

Dart API

• Add a Logger class that allows users to control how messages are printed by stylesheets.

• Add a logger parameter to compile(), compileAsync(), compileString(), and compileStringAsync().

Node JS API

• Import URLs passed to importers are no longer normalized. For example, if a stylesheet contains @import "./foo.scss", importers will now receive "./foo.scss" rather than "foo.scss".

1.0.0-beta.5.3

• Support hard tabs in the indented syntax.

• Improve the formatting of comments that don't start on the same line as the opening /*.

• Preserve whitespace after and in media queries in compressed mode.

Indented Syntax

• Properly parse multi-line selectors.

• Don't deadlock on /* comments.

• Don't add an extra */ to comments that already have it.

• Preserve empty lines in /* comments.

1.0.0-beta.5.2

• Fix a bug where some colors would crash compressed mode.

1.0.0-beta.5.1

• Add a compressed output style.

• Emit a warning when && is used, since it's probably not what the user means.

• round() now returns the correct results for negative numbers that should round down.

• var() may now be passed in place of multiple arguments to rgb(), rgba(), hsl() and hsla().

• Fix some cases where equivalent numbers wouldn't count as the same keys in maps.

• Fix a bug where multiplication like (1/1px) * (1px/1) wouldn't properly cancel out units.

• Fix a bug where dividing by a compatible unit would produce an invalid result.

• Remove a non-sh-compatible idiom from the standalone shell script.

Dart API

• Add a functions parameter to compile(), compleString(), compileAsync(), and compileStringAsync(). This allows users to define custom functions in Dart that can be invoked from Sass stylesheets.

• Expose the Callable and AsyncCallable types, which represent functions that can be invoked from Sass.

• Expose the Value type and its subclasses, as well as the top-level sassTrue, sassFalse, and sassNull values, which represent Sass values that may be passed into or returned from custom functions.

• Expose the OutputStyle enum, and add a style parameter to compile(), compleString(), compileAsync(), and compileStringAsync() that allows users to control the output style.

Node JS API

• Support the functions option.

• Support the "compressed" value for the outputStyle option.

1.0.0-beta.4

• Support unquoted imports in the indented syntax.

• Fix a crash when :not(...) extends a selector that appears in :not(:not(...)).

Node JS API

• Add support for asynchronous importers to render() and renderSync().

Dart API

• Add compileAsync() and compileStringAsync() methods. These run asynchronously, which allows them to take asynchronous importers (see below).

• Add an AsyncImporter class. This allows imports to be resolved asynchronously in case no synchronous APIs are available. AsyncImporters are only compatible with compileAysnc() and compileStringAsync().

1.0.0-beta.3

• Properly parse numbers with exponents.

• Don't crash when evaluating CSS variables whose names are entirely interpolated (for example, #{--foo}: ...).

Node JS API

• Add support for the importer option to render() and renderSync(). Only synchronous importers are currently supported.

Dart API

• Added an Importer class. This can be extended by users to provide support for custom resolution for @import rules.

• Added built-in FilesystemImporter and PackageImporter implementations that support resolving file: and package: URLs, respectively.

• Added an importers argument to the compile() and compileString() functions that provides Importers to use when resolving @import rules.

• Added a loadPaths argument to the compile() and compileString() functions that provides paths to search for stylesheets when resolving @import rules. This is a shorthand for passing FilesystemImporters to the importers argument.

1.0.0-beta.2

• Add support for the ::slotted() pseudo-element.

• Generated transparent colors will now be emitted as rgba(0, 0, 0, 0) rather than transparent. This works around a bug wherein IE incorrectly handles the latter format.

Command-Line Interface

• Improve the logic for whether to use terminal colors by default.

Node JS API

• Add support for data, includePaths, indentedSyntax, lineFeed, indentWidth, and indentType options to render() and renderSync().

• The result object returned by render() and renderSync() now includes the stats object which provides metadata about the compilation process.

• The error object thrown by render() and renderSync() now includes line, column, file, status, and formatted fields. The message field and toString() also provide more information.

Dart API

• Add a renderString() method for rendering Sass source that's not in a file on disk.

1.0.0-beta.1

• Drop support for the reference combinator. This has been removed from the spec, and will be deprecated and eventually removed in other implementations.

• Trust type annotations when compiling to JavaScript, which makes it substantially faster.

• Compile to minified JavaScript, which decreases the code size substantially and makes startup a little faster.

• Fix a crash when inspecting a string expression that ended in "\a".

• Fix a bug where declarations and @extend were allowed outside of a style rule in certain circumstances.

• Fix not in parentheses in @supports conditions.

• Allow url as an identifier name.

• Properly parse /***/ in selectors.

• Properly parse unary operators immediately after commas.

• Match Ruby Sass's rounding behavior for all functions.

• Allow \ at the beginning of a selector in the indented syntax.

• Fix a number of @extend bugs:

  • selector-extend() and selector-replace() now allow compound selector extendees.

  • Remove the universal selector * when unifying with other selectors.

  • Properly unify the result of multiple simple selectors in the same compound selector being extended.

  • Properly handle extensions being extended.

  • Properly follow the first law of @extend.

  • Fix selector specificity tracking to follow the second law of @extend.

  • Allow extensions that match selectors but fail to unify.

  • Partially-extended selectors are no longer used as parent selectors.

  • Fix an edge case where both the extender and the extended selector have invalid combinator sequences.

  • Don't crash with a "Bad state: no element" error in certain edge cases.

1.0.0-alpha.9

• Elements without a namespace (such as div) are no longer unified with elements with the empty namespace (such as |div). This unification didn't match the results returned by is-superselector(), and was not guaranteed to be valid.

• str-slice() now correctly returns "" when $end-at is negative and points before the beginning of the string.

• Interpolation in quoted strings now properly preserves newlines.

• Don't crash when passing only $hue or no keyword arguments to adjust-color(), scale-color(), or change-color().
