Its README says it started as a thin wrapper around Andy Balholm's Go Cascadia package and grew into a more capable selector-testing and extraction tool. ### Adoption history The official README documents binary releases, Debian/Ubuntu installation, distro packages through the author's Cloudsmith repository, and Homebrew packaging. GitHub metadata shows a small but active open-source utility with wiki documentation and cross-platform release artifacts. Homebrew analytics show modest niche use, with 190 installs in the last 365 days in the formula API. ### How it is used Users pass an input file or stdin, a CSS selector, and an output target. The tool supports text output, raw output, block and piece extraction, wrapped HTML output, and CSV/TSV-style table output for scraping workflows. ### Why package nerds care Cascadia is package-nerd useful because it exposes a library-grade CSS selector engine as a tiny shell tool. It fits scripts, data-cleaning one-liners, and package tests where pulling in a browser or a larger scraper would be excessive. ### Timeline - 2016: Public GitHub repository created and copyright range begins in the CLI help. - 2025: README example shows version 1.5.0 built on 2025-11-10. - 2026: Homebrew formula packages v1.5.1 and tracks the GitHub release tarball. ### Related projects - andybalholm/cascadia provides the Go CSS selector package wrapped by this CLI. - andrew-d/goscrape is cited by the README as an influence for block and piece extraction concepts. ### 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:** cascadia - **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 - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [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. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [flyscrape](https://www.automicvault.com/pkg/brew/flyscrape/) - Shares av.db curated category or tags: cli, developer-tools, web-scraping. - [htmlq](https://www.automicvault.com/pkg/brew/htmlq/) - Shares av.db curated category or tags: cli, css-selectors, developer-tools, html. - [htmltest](https://www.automicvault.com/pkg/brew/htmltest/) - Shares av.db curated category or tags: cli, developer-tools, go, html. - [pit](https://www.automicvault.com/pkg/brew/pit/) - Shares av.db curated category or tags: cli, developer-tools, web-scraping. - [shub](https://www.automicvault.com/pkg/brew/shub/) - Shares av.db curated category or tags: cli, developer-tools, web-scraping. - [templ](https://www.automicvault.com/pkg/brew/templ/) - Shares av.db curated category or tags: cli, developer-tools, go, html. - [adr-viewer](https://www.automicvault.com/pkg/brew/adr-viewer/) - Shares av.db curated category or tags: cli, developer-tools, html. - [aha](https://www.automicvault.com/pkg/brew/aha/) - Shares av.db curated category or tags: cli, developer-tools, html. - [go-rice](https://www.automicvault.com/pkg/brew/go-rice/) - Both packages touch the same language runtime or ecosystem.
