NAME

URI::XSEscape - Fast XS URI-escaping library, replacing URI::Escape.

VERSION

Version 0.001000

SYNOPSIS

    # load once
    use URI::XSEscape;

    # keep using URI::Escape as you wish

DESCRIPTION

By loading URI::XSEscape anywhere, you replace any usage of URI::Escape with a faster C implementation.

You can continue to use URI::Escape and any other module that depends on it just like you did before. It's just faster now.

When you have loaded URI::XSEscape, you can control the overriding of URI::Escape's methods using the environment variable PERL_URI_XSESCAPE. Only if it is explicitly set to zero, the methods in URI::Escape will not be overwritten. This is how the benchmark below is run.

METHODS/ATTRIBUTES

These match the API described in URI::Escape.

Please see those modules for documentation on what these methods and attributes are.

uri_escape

uri_escape_utf8

uri_unescape

BENCHMARKS

For the common case, which is calling uri_escape with a single argument, and calling uri_unescape, URI::XSEscape runs between 25 and 34 times faster than URI::Escape. The other cases are also faster, but the difference is not that noticeable.
