Crawls web pages and prints any link it can find.

• fast html SAX-parser (powered by golang.org/x/net/html)
• small (<3000 SLOC), idiomatic, 100% test covered codebase
• grabs most of useful resources urls (pics, videos, audios, forms, etc...)
• found urls are streamed to stdout and guranteed to be unique (with fragments omitted)
• scan depth (limited by starting host and path, by default - 0) can be configured
• can crawl rules and sitemaps from robots.txt
• brute mode - scan html comments for urls (this can lead to bogus results)
• make use of HTTP_PROXY / HTTPS_PROXY environment values
• directory-only scan mode (aka fast-scan)
• user-defined cookies, in curl-compatible format (i.e. -cookie "ONE=1; TWO=2" -cookie "ITS=ME" -cookie @cookie-file)
• user-defined headers, same as curl: -header "ONE: 1" -header "TWO: 2" -header @headers-file

• binaries for Linux, FreeBSD, macOS and Windows

Crawley is available in the AUR. Linux distributions with access to it can obtain the package from here. You can also use your favourite AUR helper to install it, e. g. paru -S crawley-bin.
