For + example, `:nth-child(1)` can be converted to `:first-child`, and + `p:nth-last-child(2n + 1)` converts to `p:nth-last-child(odd)`. + +# 2.0.7 + +* Fixes a regression where postcss-minify-selectors would transform `[title=""]` + into `[title=]` (thanks to @arperry). + +# 2.0.6 + +* Performance tweaks; now calls `Node#toString()` ~50% less often, removed dead + branches, extracted each node type into a separate transformer function. +* Resolves an issue where extraneous whitespace around a case-insensitive + attribute selector (`[href="foo" i]`) would not be removed. + +# 2.0.5 + +* Updated postcss-selector-parser to `2.0.0`. + +# 2.0.4 + +* Now compiled with babel 6. + +# 2.0.3 + +* Fixed an issue where `[a="-"]` was incorrectly minified to `[a=-]`. + +# 2.0.2 + +* Fixed a crash with Polymer mixins; now the module will pass through any + selector string with a trailing colon. + +# 2.0.1 + +* Replaced javascript-natural-sort with alphanum-sort (thanks to @TrySound). + +# 2.0.0 + +* Upgraded to PostCSS 5. +* At-rule parameter minification was extracted out of this module into + postcss-minify-params (thanks to @TrySound). + +# 1.5.0 + +* Added support for converting pseudo elements with double colon syntax to + the single colon syntax. + +# 1.4.7 + +* Further performance improvements by using less postcss-selector-parser + iterations. + +# 1.4.6 + +* Bump normalize-selector to `0.2.0`, decreases overall package weight. +* Speed up node iteration by calling `eachInside` once rather than twice. + +# 1.4.5 + +* Update normalize-selector to cut down package weight. + +# 1.4.4 + +* Fixed an integration issue with postcss-font-magician. + +# 1.4.3 + +* Fixed an issue where `.from` was transformed to `0%`. + +# 1.4.2 + +* Bump dependencies. +* Fixes for PostCSS plugin guidelines. + +# 1.4.1 + +* Fixes incorrect deduplication of pseudo selector rules. + +# 1.4.0 + +* Update to postcss-selector-parser to greatly improve parsing logic. + +# 1.3.1 + +* Fixes a crash when nothing was passed to `node-balanced`. + +# 1.3.0 + +* Now uses the PostCSS `4.1` plugin API. + +# 1.2.1 + +* Passes original test case in issue 1. + +# 1.2.0 + +* Does not touch quoted values in attribute selectors. +* No longer will mangle values such as `2100%` in keyframes. + +# 1.1.0 + +* Now minifies `from` to `0%` and `100%` to `to` in keyframe declarations. + +# 1.0.0 + +* Initial release. diff --git a/node_modules/postcss-minify-selectors/LICENSE-MIT b/node_modules/postcss-minify-selectors/LICENSE-MIT new file mode 100644 index 00000000..fd0e863a --- /dev/null +++ b/node_modules/postcss-minify-selectors/LICENSE-MIT @@ -0,0 +1,22 @@ +Copyright (c) Ben Briggs <beneb.info@gmail.com> (http://beneb.info) + +Permission is hereby granted, free of charge, to any person +obtaining a copy of this software and associated documentation +files (the "Software"), to deal in the Software without +restriction, including without limitation the rights to use, +copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the +Software is furnished to do so, subject to the following +conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES +OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.
