Adding Fuzzyurl to Your Project

To use Fuzzyurl with your projects, edit your mix.exs file and add it as a dependency:

defp deps do
  [{:fuzzyurl, "~> 0.9.0"}]


Fuzzyurl provides two related functions: non-strict parsing of URLs or URL-like strings into their component pieces (protocol, username, password, hostname, port, path, query, and fragment), and fuzzy matching of URLs and URL patterns.

Specifically, URLs that look like this:

[protocol ://] [username [: password] @] [hostname] [: port] [/ path] [? query] [# fragment]

Fuzzyurls can be constructed using some or all of the above fields, optionally replacing some or all of those fields with a * wildcard if you wish to use the Fuzzyurl as a URL mask.

Parsing URLs

iex> f = Fuzzyurl.from_string("https://api.example.com/users/123?full=true")
%Fuzzyurl{fragment: nil, hostname: "api.example.com", password: nil, path: "/users/123", port: nil, protocol: "https", query: "full=true", username: nil}
iex> f.protocol
iex> f.hostname
iex> f.query

Constructing URLs

iex> f = Fuzzyurl.new(hostname: "example.com", protocol: "http", port: "8080")
%Fuzzyurl{fragment: nil, hostname: "example.com", password: nil, path: nil, port: "8080", protocol: "http", query: nil, username: nil}
iex> Fuzzyurl.to_string(f)

Matching URLs

Fuzzyurl supports wildcard matching:

  • * matches anything, including nil.
  • foo* matches foo, foobar, foo/bar, etc.
  • *bar matches bar, foobar, foo/bar, etc.

Path and hostname matching allows the use of a greedier wildcard ** in addition to the naive wildcard *:

  • *.example.com matches filsrv-01.corp.example.com but not example.com.
  • **.example.com matches filsrv-01.corp.example.com and example.com.
  • /some/path/* matches /some/path/foo/bar and /some/path/ but not /some/path
  • /some/path/** matches /some/path/foo/bar and /some/path/ and /some/path

The Fuzzyurl.mask/0 and Fuzzyurl.mask/1 functions aid in the creation of URL masks.

iex> m = Fuzzyurl.mask
%Fuzzyurl{fragment: "*", hostname: "*", password: "*", path: "*", port: "*", protocol: "*", query: "*", username: "*"}
iex> Fuzzyurl.matches?(m, "http://example.com/a/b/c")

iex> m2 = Fuzzyurl.mask(path: "/a/b/**")
%Fuzzyurl{fragment: "*", hostname: "*", password: "*", path: "/a/b/**", port: "*", protocol: "*", query: "*", username: "*"}
iex> Fuzzyurl.matches?(m2, "https://example.com/a/b/")
iex> Fuzzyurl.matches?(m2, "git+ssh://[email protected]/a/b")
iex> Fuzzyurl.matches?(m2, "https://example.com/a/bar")

Fuzzyurl.best_match, given a list of URL masks and a URL, will return the mask which most closely matches the URL:

iex> masks = ["/foo/*", "/foo/bar", Fuzzyurl.mask]
iex> Fuzzyurl.best_match(masks, "http://example.com/foo/bar")

If you'd prefer the list index of the best-matching URL mask, use Fuzzyurl.best_match_index instead:

iex> masks = ["/foo/*", "/foo/bar", Fuzzyurl.mask]
iex> Fuzzyurl.best_match_index(masks, "http://example.com/foo/bar")
