Project history and usage

Cascadia is a Go command-line wrapper around the Go Cascadia CSS selector package, aimed at testing selectors and extracting HTML/XML content without writing a Go program.

Project history

The project began publicly in 2016 under Tong Sun's GitHub account. 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.
