# `url`

This library implements validation, parsing, generating, and normalization of URLs, which can be represented as atoms, character lists, or code lists. It currently supports the following URL schemes:

Web protocols:

- `http`

- `https`

- `ws`

- `wss`

- `gopher`

File transfer and version control:

- `ftp`

- `ftps`

- `sftp`

- `git`

File access:

- `file`

Databases:

- `jdbc`

- `mongodb`

- `mysql`

- `postgresql`

Email and news:

- `mailto`

- `news`

- `nntp`

Media streaming:

- `mms`

- `rtmp`

- `rtsp`

Shell access:

- `ssh`

- `telnet`

Directory services:

- `ldap`

- `ldaps`

Other protocols:

- `tel`

- `urn`

The library predicates are defined in the `url(_Representation_)` parametric object where `_Representation_` can be one of:

- `atom` - strings are represented as atoms

- `chars` - strings are represented as lists of characters

- `codes` - strings are represented as lists of character codes

The parameter must be bound when sending messages to the object.
