Project history and usage

xurls is Daniel Marti's Go library and CLI for extracting URLs from text with curated regular expressions. It exposes strict and relaxed matchers as Go APIs and ships `cmd/xurls` for shell pipelines.

Project history

The GitHub repository was created in January 2015 and grew as a small Go package centered on reusable `regexp.Regexp` values. The README documents the v2 module path `mvdan.cc/xurls/v2`, strict and relaxed matching, cached compiled expressions, and a CLI install path via `go install`.

The release history shows the project adapting to URL edge cases rather than trying to become a full parser: Go modules, internationalized and punycode TLD handling, markdown punctuation cases, large-input CLI fixes, `xurls -fix`, redirect handling, and regular updates to TLD and scheme lists.

Adoption history

xurls is used as both a library and a command because URL extraction from arbitrary text appears in log processing, documentation checks, chat exports, feed cleanup, and static analysis. Its package-manager presence points to a developer-tool audience rather than a large end-user app.

How it is used

As a CLI, `xurls` reads text and prints matched URLs for shell pipelines. As a Go package, callers use `xurls.Relaxed()` or `xurls.Strict()` and then call standard `regexp` methods such as `FindString` or `FindAllString`.

Why package nerds care

xurls is package-nerd interesting because it packages a messy text-processing convention as a tiny, reproducible Go tool. Its history is mostly a record of edge cases in the public URL ecosystem: new schemes, TLD churn, Unicode, markdown punctuation, email ambiguity, and redirect cleanup.
