.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a filter plugin for Data::Printer. It filters through several
web-related objects and display their content in a (hopefully!) more userful
way than a regular dump.
.SH "PARSED MODULES"
.IX Header "PARSED MODULES"
.SS "\s-1JSON\s0"
.IX Subsection "JSON"
Because Perl has no \f(CW\*(C`true\*(C'\fR or \f(CW\*(C`false\*(C'\fR tokens, many \s-1JSON\s0 parsers implement
boolean objects to represent those. With this filter, you'll get \*(L"true\*(R" and
\&\*(L"false\*(R" (which is what probably you want to see) instead of an object dump
on those booleans. This module filters through the following modules:
.PP
\&\f(CW\*(C`JSON::PP\*(C'\fR, \f(CW\*(C`JSON::XS\*(C'\fR, \f(CW\*(C`JSON\*(C'\fR, \f(CW\*(C`JSON::MaybeXS\*(C'\fR, \f(CW\*(C`Cpanel::JSON::XS\*(C'\fR,
\&\f(CW\*(C`JSON\*(C'\fR, \f(CW\*(C`JSON::SL\*(C'\fR, \f(CW\*(C`Pegex::JSON\*(C'\fR, \f(CW\*(C`JSON::Tiny\*(C'\fR, \f(CW\*(C`JSON::Any\*(C'\fR,
\&\f(CW\*(C`JSON::DWIW\*(C'\fR and \f(CW\*(C`Mojo::JSON\*(C'\fR.
.PP
Also, if you use \f(CW\*(C`JSON::Typist\*(C'\fR to parse your \s-1JSON\s0 strings, a Data::Printer
dump using this filter will always properly print numbers as numbers and
strings as strings.
.SS "\s-1COOKIES\s0"
.IX Subsection "COOKIES"
This filter is able to handle cookies from \f(CW\*(C`Dancer\*(C'\fR/\f(CW\*(C`Dancer2\*(C'\fR and
\&\f(CW\*(C`Mojolicious\*(C'\fR frameworks. Other frameworks like \f(CW\*(C`Catalyst\*(C'\fR rely on
\&\f(CW\*(C`HTTP::CookieJar\*(C'\fR and \f(CW\*(C`HTTP::Cookies\*(C'\fR, which simply store them in a
hash, not an object.
.SS "\s-1HTTP REQUEST/RESPONSE\s0"
.IX Subsection "HTTP REQUEST/RESPONSE"
\&\f(CW\*(C`HTTP::Request\*(C'\fR and \f(CW\*(C`HTTP::Response\*(C'\fR objects are filtered to display
headers and content. These are returned by LWP::UserAgent,
WWW::Mechanize and many others.
.PP
If the response comes from chained redirects (that the source HTTP::Response
object knows about), this filter will show you the entire redirect chain
above the actual object. You may disable this by changing the
\&\f(CW\*(C`filter_web.show_redirect\*(C'\fR option.
