scissors 0.6.4

A CSS minifier / tree-shaker for AngularDart 1.x / Angular2.

Current development tree

...

0.6.4 (2016-06-30)

Bugfixes

• Fix skipping of image inlining for unaffected files (see issue #53)

0.6.3 (2016-06-14)

Bugfixes

• Fixed bidirectionalization of @media rules.
• Fixed race condition + some embarrassing typos in Sass settings (caused some includes to not be resolved)
• Merged SassC & ImageInlining transformers to avoid some errors "Both {SassC on ..., ImageInlining on ...} emitted the same file."
• Switched hidden onlyCompileOutOfDateSass option's default to false (caused pub to hang when used in combination with some other transformers)

Features

• Removed experimental scissors/src/checker/transformer, which feature was integrated to the Dart Linter package from version 0.1.19.
• Switched some defaults around: pruneCss: false, imageInlining: inlineInlinedImages

0.6.2 (2016-06-02)

Features

• Added experimental scissors/src/checker/transformer that detects unawaited futures. These extra static checks are slow, but prevent accidental fire-and-forget of futures within async method bodies.

0.6.1 (2016-05-26)

Bugfixes

• Fixed Bidi CSS which had been wrongly simplified (issue #43)

0.6.0 (2016-03-16)

Bugfixes

• Switched from a code_transformers dependency to a transformer_test dev dependency (issue #35)

0.5.0 (2016-03-14)

Features

• Added a sourcemap-stripping transformer, usable standalone or in scissors/permutations_transformer with stripSourceMaps: true (relevant only when the $dart2js transformer has sourceMaps: true)
• Added Compass polyfills for prefix-usage, browsers, browser-prefixes, compact (makes lots of Compass mixins to work well)

Bugfixes

• CSS pruning:

  • Handle Angular2 [attr.name] and [class.name] syntaxes in CSS pruning (issues #30 & #31)
  • Skip :host rules (issue #29)

• Bidirectional CSS:

  • Fix Css mirroring to handle multiple selectors in RuleSet
  • Transformer is now an aggregate (more solid interaction with other transformers)

• Follow symlinks in path resolution logic.

• scissors-sassc now automatically finds compass stylesheets

0.4.3 (2016-03-04)

Features

• Introduced scissors-sassc binary that wraps sassc and adds inline-image support.

0.4.2 (2016-03-03)

Bugfixes

• Fixed "Bad state: Setting sasscArgs wasn't read yet." (issue #27).

0.4.1 (2016-01-19)

Bugfixes

• Simplified bidirectional CSS output (issue #23): now produces smaller code.

0.4.0 (2016-01-19)

Features

• Added scissors/css_mirroring_transformer that makes CSS files to support bidirectional layouts (uses CSSJanus. Given foo { color: blue; float: left }, it generates:

  foo { color: blue }
  :host-context([dir="ltr"]) foo { float: left }
  :host-context([dir="rtl"]) foo { float: right }
  

  So you just need the supporting code in your main.dart to support bidirectional layouts (see example/mirroring):

  document.body.dir = Bidi.isRtlLanguage(Intl.getCurrentLocale()) ? 'rtl' : 'ltr';
  

  This feature is also available in the regular scissors transformer, but it must be enabled with bidiCss: true.

• Added compiledCssExtension option to control how foo.scss is compiled: append yields foo.scss.css (default), while replace produces foo.css.

Bugfixes

• Fixed support for -I / --load-path arguments in sasscArgs setting (issue #21)

0.3.0 (2016-01-13)

Features

• Added scissors-sassc-compass binary that provides a best-effort replacement for Compass using SassC: it processes any inline-image function detected, and falls back to using plain Compass if SassC fails to compile the input (or if it does not understand the command-line arguments).

Bugfixes

• scissors/permutations_transformer: generate sourcemaps for permutations (limited to source map of main fragment; shouldn't hurt much if deferred parts only contain messages and template caches)

0.2.2 (2016-01-05)

Bugfixes

• Systematically resolve paths from settings (for pngcrush, sassc, etc)
• scissors/permutations_transformer: generate permutation for defaultLocale (language in which the messages are written in the source, defaults to en_US)

0.2.1 (2015-12-14)

Bugfixes

• Resolve files with the .packages file to prepare for disappearance of packages/.
• scissors/transformer: made Sass transformer really lazy.
• scissors/permutations_transformer: hard-fail when parts check fails (consume the .dart.js)
• scissors/reloader/transformer: added named argument timestampBaseUrl to setupReloader.

0.2.0 (2015-11-19)

Features

• Added inline_images.dart entry point for standalone inlining

Bugfixes

• Improved asset file resolution with package_name/path pattern.
• Made permutations transformer lazy

0.1.9 (2015-11-15)

Features

• Added new scissors/reloader/transformer + runtime lib that allow instant reload whenever assets are updated (triggered at the end of the pub build). Reloader usage is erased from release builds by default (respecting source maps).
• Don't prune css in debug by default

Bugfixes

• Sass transformer respects existing .scss.css input and only rebuilds them from the .scss sources when it's out of date (timestamp-based; can be disabled with onlyCompileOutOfDateSass: false).

0.1.8 (2015-11-14)

This version comes with a massive refactoring that splits out most features into their own transformer. Please note that there are still only 3 officially-supported transformer entry points:

• scissors/transformer (lazy Sass compilation, CSS and image optimizations)
• scissors/eager_transformer (eager version of the previous: builds all the assets upfront when pub serve is run)
• scissors/permutations_transformer (lazy locale-specific permutations with optional Closure Compilation to reoptimize the outputs)

Bugfixes

• Permutations transformer (scissors/permutations_transformer):

  • Permutations are now built lazily (fixes pub serve + Dartium experience)
  • Disabled reoptimizePermutations by default
  • Respect javaPath when running the Closure Compiler.
  • Added expectedPartCounts check (takes a map of .dart.js script path to number of expected parts, see example/permutations)

• Fixed path resolution regression (dotted package names)

0.1.7 (2015-11-12)

Bugfixes

• Fixed image linking (imageInlining: linkInlinedImages), with a new packageRewrites setting (with fromPattern,toReplacement syntax; defaults to ^package:,packages/, which works well with pub serve).
• Fixed usage of pngCrushPath setting.

0.1.6 (2015-11-12)

Bugfixes

• Fixed support of wildcard * CSS rules.

Features

• Added support for LTR/RTL-specific parts in scissors/permutations_transformer (see example/permutations).

0.1.5 (2015-11-12)

Bugfixes

• Fixed base64 format in inline-image

Features

• Added experimental SVG optimization (poor-man heuristics, enabled in release, disable with optimizeSvg: false)

• Added experimental PNG optimization relying on pngcrush (enabled in release, disable with optimizePng: false, provide path to pngcrush with pngCrushPath: path/to/pngcrush)

• Added imageInlining setting to control image inlining inside CSS files, accepts values:

  • inlineAllUrls: inlines inline-image and url references
  • inlineInlinedImages: inlines inline-image only (default in release mode)
  • linkInlinedImages: rewrites inline-image references into url references (default in debug mode): images are not inlined.
  • disablePass: don't touch inline-image references (may produce invalid CSS).

• Added experimental scissors/permutations_transformer transformer that generates locale-specific .js artefacts when using defer-loaded messages (package:intl).

0.1.4 (2015-10-30)

Bugfixes

• Cleaner path resolution logic (easier to override)
• Stricter regexp in recursive sass imports consumer

0.1.3 (2015-10-28)

Features

• The transformer is now lazy by default, which speeds up startup time of pub serve (use scissors/eager_transformer to force eager transform)

• Sass compilation supports Compass's inline-image helper to inline images.

• Rebuilds .css files when any transitive .sass import is modified:

  • Requires pub serve --force-poll
  • The default (lazy) transformer will just invalidate stale resources, while scissors/eager_transformer will eagerly rebuild them.

0.1.2 (2015-10-26)

Features

• Improved sassc integration:

  • Resolving ${FOO} environment variables in sasscPath and sasscArgs settings
  • Automatically set --load-path arguments with list of root directories, with clean fork point (path_resolver.dart)
  • Output css sourcemaps

0.1.1 (2015-10-23)

Features

• Preliminary support for compiling *.scss and *.sass files with sassc.

0.1.0 (2015-10-22)

Features

• Basic support for .css pruning based on companion .html template or inlined templates in companion .dart file (Angular1 and Angular2)
• Support for ng-class and interpolated name fragments inside class in templates
