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 urlquotequote 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, ",#,<,>,`,?,{,},$,%,&,\,(,),,,=,;,:,!,@,[,],^,|,+,*
|
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.
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 buildTo setup the development environment run:
python -m pip install -e .[test]To execute the tests run
pytestThere are also some Rust-only unit tests. To execute them change into the rust subdirectory and call.
