## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.

### 时间线

- 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.
