The 2014 changelog entry for version 2.2.0 added a command-line config file named crushfile.php, which is the package's official documented config filename. ### Why package nerds care For package collectors, CSS Crush represents the period when CSS preprocessors competed on lightweight build integration, automatic prefixing, and language extensions before many of those features moved into PostCSS pipelines or native CSS. ### Timeline - 2012: 1.8.0 adds selector aliasing. - 2013: 2.0.0 raises the PHP requirement, namespaces library code, and removes several legacy IE helpers. - 2014: 2.2.0 adds crushfile.php for command-line configuration. - 2019: 3.0.0 raises the PHP requirement to 5.6 and simplifies the plugin API. - 2022: 4.0.0 raises the PHP requirement to 7. ### Related projects - CSS Crush sits in the same historical space as Sass, Less, Stylus, PostCSS-era plugins, and other CSS build tools that extended CSS before browser support caught up. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** css-crush - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [php](https://www.automicvault.com/pkg/brew/php/) - Runtime dependency declared by Homebrew. - [sassc](https://www.automicvault.com/pkg/brew/sassc/) - Shares av.db curated category or tags: cli, css, developer-tools, web-development. - [angular-cli](https://www.automicvault.com/pkg/brew/angular-cli/) - Shares av.db curated category or tags: cli, developer-tools, web-development. - [gatsby-cli](https://www.automicvault.com/pkg/brew/gatsby-cli/) - Shares av.db curated category or tags: cli, developer-tools, web-development. - [gwt](https://www.automicvault.com/pkg/brew/gwt/) - Shares av.db curated category or tags: cli, developer-tools, web-development. - [js-beautify](https://www.automicvault.com/pkg/brew/js-beautify/) - Shares av.db curated category or tags: cli, css, developer-tools, web-development. - [livereload](https://www.automicvault.com/pkg/brew/livereload/) - Shares av.db curated category or tags: cli, developer-tools, web-development. - [minify](https://www.automicvault.com/pkg/brew/minify/) - Shares av.db curated category or tags: cli, css, developer-tools, web-development. - [nuxi](https://www.automicvault.com/pkg/brew/nuxi/) - Shares av.db curated category or tags: cli, developer-tools, web-development. ## Combined YAML source View the package source record on GitHub.
