urlquote 2.2.0

Fast quoting and unquoting of urls.

Urlquote

Fast percent encoding / decoding for python.

This library is not intended to be a replacement for urllib. urllib is part of the Python standard library and should be your go-to choice to quote and unquote URLs. However, should quoting or unquoting of URLs be known to be a performance bottleneck and you are fine with the encoding described below, then by all means have fun using this library.

Usage

from urlquote import quote

quoted = quote('/El Niño/')
assert(quoted == '/El%20Ni%C3%B1o/'.encode('utf-8'))

Compatibility

Since this library uses a cffi interface it should work fine with any version of Python. For Linux the wheel has to be build against a version of libc older or equal to the version of libc on the platform the wheel will be used on.

Installation

pip install urlquote

quote operates on UTF-8-encoded bytes. If passed a string, it will encode it into UTF-8 first. It will always return UTF-8-encoded bytes. unquote behaves the same way.

Encoding

The following encodings are offered. DEFAULT_QUOTING is used in case the quoting parameter is not specified.

Name	Additional encoded characters
SIMPLE_QUOTING
DEFAULT_QUOTING	space, <,>,`,?,{,}
QUERY_QUOTING	space, ",#,<,>
PATH_SEGMENT_QUOTING	space, ",#,<,>,`,?,%,/
USERINFO_QUOTING	space, ",#,<,>,`,?,{,},/,:,;,=,@,\,[,],^,|
PYTHON_3_7_QUOTING	space, ",#,<,>,`,?,{,},$,%,&,\,(,),,,=,;,:,!,@,[,],^,|,+,*
IDEMPOTENT_QUOTING	space, ",#,<,>,`,?,{,},$,&,\,(,),,,=,;,:,!,@,[,],^,|,+,*

Non printable and non standard ASCII characters are always quoted. The PYTHON_3_7_QUOTING is going to work the same way in every Python version the name is only refering to the urllib default encoding used in Python 3.7. IDEMPOTENT_QUOTING is the same as PYTHON_3_7_QUOTING but without % to provide idempotency.

Development

This library is a thin wrapper around the Rust crate percent-encoding. It exposes part of its functionality to python via a C interface using cffi.

To build it you need to install Rust and Cargo. Than you can proceed to build the wheel with:

python -m pip install build

To setup the development environment run:

python -m pip install -e .[test]

To execute the tests run

pytest

There are also some Rust-only unit tests. To execute them change into the rust subdirectory and call.

cargo test
