URITOOLS(1)

NAME
uritools - uritools 6.0.2

This module provides RFC 3986 compliant functions for parsing, classifying and composing URIs and URI references, largely replacing the Python Standard Library's urllib.parse <https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse> module.

    >>> from uritools import uricompose, urijoin, urisplit, uriunsplit
    >>> uricompose(scheme='foo', host='example.com', port=8042,
    ...            path='/over/there', query={'name': 'ferret'},
    ...            fragment='nose')
    'foo://example.com:8042/over/there?name=ferret#nose'
    >>> parts = urisplit(_)
    >>> parts.scheme
    'foo'
    >>> parts.authority
    'example.com:8042'
    >>> parts.getport(default=80)
    8042
    >>> parts.getquerydict().get('name')
    ['ferret']
    >>> parts.isuri()
    True
    >>> parts.isabsuri()
    False
    >>> urijoin(uriunsplit(parts), '/right/here?name=swallow#beak')
    'foo://example.com:8042/right/here?name=swallow#beak'

For various reasons, urllib.parse <https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse> and its Python 2 predecessor urlparse are not compliant with current Internet standards. As stated in Lib/urllib/parse.py <https://github.com/python/cpython/blob/main/Lib/urllib/parse.py#L22>: RFC 3986 is considered the current standard and any future changes to urlparse module should conform with it. The urlparse module is currently not entirely compliant with this RFC due to defacto scenarios for parsing, and for backward compatibility purposes, some parsing quirks from older RFCs are retained.

This module aims to provide fully RFC 3986 compliant replacements for the most commonly used functions found in urllib.parse <https://docs.python.org/3/library/urllib.parse.html#module-urllib.parse>. It also includes functions for distinguishing between the different forms of URIs and URI references, and for conveniently creating URIs from their individual components.

See also:

RFC 3986 <https://datatracker.ietf.org/doc/html/rfc3986.html> - Uniform Resource Identifier (URI): Generic Syntax
    The current Internet standard (STD66) defining URI syntax, to which any changes to uritools should conform. If deviations are observed, the module's implementation should be changed, even if this means breaking backward compatibility.

URI CLASSIFICATION

According to RFC 3986, a URI reference is either a URI or a relative reference. If the URI reference's prefix does not match the syntax of a scheme followed by its colon separator, then the URI reference is a relative reference.

A relative reference that begins with two slash characters is termed a network-path reference. A relative reference that begins with a single slash character is termed an absolute-path reference. A relative reference that does not begin with a slash character is termed a relative-path reference.

When a URI reference refers to a URI that is, aside from its fragment component, identical to the base URI, that reference is called a same-document reference. Examples of same-document references are relative references that are empty or include only the number sign ("#") separator followed by a fragment identifier.

A URI without a fragment identifier is termed an absolute URI. A base URI, for example, must be an absolute URI. If the base URI is obtained from a URI reference, then that reference must be stripped of any fragment component prior to its use as a base URI.

uritools.isuri(uristring)
    Return True if uristring is a URI.

uritools.isabsuri(uristring)
    Return True if uristring is an absolute URI.

uritools.isnetpath(uristring)
    Return True if uristring is a network-path reference.

uritools.isabspath(uristring)
    Return True if uristring is an absolute-path reference.

uritools.isrelpath(uristring)
    Return True if uristring is a relative-path reference.

uritools.issamedoc(uristring)
    Return True if uristring is a same-document reference.

URI COMPOSITION

uritools.uricompose(scheme=None, authority=None, path='', query=None, fragment=None, userinfo=None, host=None, port=None, querysep='&', encoding='utf-8')
    Compose a URI reference string from its individual components.

    All components may be specified as either Unicode strings, which will be encoded according to encoding, or bytes <https://docs.python.org/3/library/stdtypes.html#bytes> objects.

    authority may also be passed a three-item iterable specifying userinfo, host and port subcomponents. If both authority and any of the userinfo, host or port keyword arguments are given, the keyword argument will override the corresponding authority subcomponent.

    query may also be passed a mapping object or a sequence of two-element tuples, which will be converted to a string of name=value pairs separated by querysep.

    The returned URI reference is of type str <https://docs.python.org/3/library/stdtypes.html#str>.

uritools.urijoin(base, ref, strict=False)
    Convert a URI reference relative to a base URI to its target URI string.

    If strict is False, a scheme in the reference is ignored if it is identical to the base URI's scheme.

uritools.uriunsplit(parts)
    Combine the elements of a five-item iterable into a URI reference's string representation.

URI DECOMPOSITION

uritools.uridefrag(uristring)
    Remove an existing fragment component from a URI reference string.

    The return value is an instance of a subclass of collections.namedtuple with the following read-only attributes:
    Attribute | Index | Value
    uri | 0 | Absolute URI, or relative reference without a fragment identifier
    fragment | 1 | Fragment identifier, or None if no fragment was present

uritools.urisplit(uristring)
    Split a well-formed URI reference string into a tuple with five components corresponding to a URI's general structure:

        <scheme>://<authority>/<path>?<query>#<fragment>

    The return value is an instance of a subclass of collections.namedtuple with the following read-only attributes:
    Attribute | Index | Value
    scheme | 0 | URI scheme, or None if not present
    authority | 1 | Authority component, or None if not present
    path | 2 | Path component, always present but may be empty
    query | 3 | Query component, or None if not present
    fragment | 4 | Fragment identifier, or None if not present
    userinfo |  | Userinfo subcomponent of authority, or None if not present
    host |  | Host subcomponent of authority, or None if not present
    port |  | Port subcomponent of authority as a (possibly empty) string, or None if not present

URI ENCODING

uritools.uridecode(uristring, encoding='utf-8', errors='strict')
    Decode a URI string or string component.

    If encoding is set to None, return the percent-decoded uristring as a bytes <https://docs.python.org/3/library/stdtypes.html#bytes> object. Otherwise, replace any percent-encodings and decode uristring using the codec registered for encoding, returning a Unicode string.

uritools.uriencode(uristring, safe='', encoding='utf-8', errors='strict')
    Encode a URI string or string component.

    If uristring is a bytes <https://docs.python.org/3/library/stdtypes.html#bytes> object, replace any characters not in UNRESERVED or safe with their corresponding percent-encodings and return the result as a bytes <https://docs.python.org/3/library/stdtypes.html#bytes> object. Otherwise, encode uristring using the codec registered for encoding before replacing any percent encodings.

STRUCTURED PARSE RESULTS

The result objects from the uridefrag() and urisplit() functions are instances of subclasses of collections.namedtuple. These objects contain the attributes described in the function documentation, as well as some additional convenience methods.

class uritools.DefragResult(uri, fragment)
    Class to hold uridefrag() results.

getfragment(default=None, encoding='utf-8', errors='strict')
    Return the decoded fragment identifier, or default if the original URI did not contain a fragment component.

geturi()
    Return the recombined version of the original URI as a string.

class uritools.SplitResult(scheme, authority, path, query, fragment)
    Base class to hold urisplit() results.

getauthority(default=None, encoding='utf-8', errors='strict')
    Return the decoded userinfo, host and port subcomponents of the URI authority as a three-item tuple.

getfragment(default=None, encoding='utf-8', errors='strict')
    Return the decoded fragment identifier, or default if the original URI reference did not contain a fragment component.

gethost(default=None, errors='strict')
    Return the decoded host subcomponent of the URI authority as a string or an ipaddress <https://docs.python.org/3/library/ipaddress.html#module-ipaddress> address object, or default if the original URI reference did not contain a host.

getpath(encoding='utf-8', errors='strict')
    Return the normalized decoded URI path.

getport(default=None)
    Return the port subcomponent of the URI authority as an int <https://docs.python.org/3/library/functions.html#int>, or default if the original URI reference did not contain a port or if the port was empty.

getquery(default=None, encoding='utf-8', errors='strict')
    Return the decoded query string, or default if the original URI reference did not contain a query component.

getquerydict(sep='&', encoding='utf-8', errors='strict')
    Split the query component into individual name=value pairs separated by sep and return a dictionary of query variables. The dictionary keys are the unique query variable names and the values are lists of values for each name.
