ppURI

A pyparsing based URI parser/scanner library.

Install using pip or your tool of choice e.g.

pip install ppuri
poetry add ppuri

Usage

Parsing

Either import ppuri.uri and use the parse function to match and parse against all URI schemes e.g.

from ppuri import uri
info = uri.parse("https://www.example.com:443/a.path?q=aparam#afragment")
print(info)

prints

{
  "authority": { "address": "www.example.com", "port": "443" },
  "fragment": "afragment",
  "parameters": [{ "name": "q", "value": "aparam" }],
  "path": "/a.path",
  "scheme": "https",
  "uri": "https://www.example.com:443/a.path?q=aparam#afragment"
}

Or import a specific scheme's parse function.

from ppuri.scheme import http
info = http.parse()

and use that to parse

Scanning

To scan text for URIs use the scan method
