Implementation of the purl (package url) specification.

See the documentation.

iex> Purl.new("pkg:hex/purl")
{:ok, %Purl{type: "hex", name: "purl"}}
iex> Purl.to_string(%Purl{type: "hex", name: "purl"})
"pkg:hex/purl"

To handle the purl record, first include the header:

-include_lib("purl/include/purl.hrl").

> purl:new("pkg:hex/purl").
{ok, #purl{type = <<"hex">>, name = <<"purl">>}}
> purl:to_string(#purl{type = <<"hex">>, name = <<"purl">>})
<<"pkg:hex/purl">>
