/*
From http://blogs.perl.org/users/nick_wellnhofer/2015/03/writing-xs-like-a-pro---perl-no-get-context-and-static-functions.html
The perlxs man page recommends to define the PERL_NO_GET_CONTEXT macro before including EXTERN.h, perl.h, and XSUB.h.
If this macro is defined, it is assumed that the interpreter context is passed as a parameter to every function.
If it's undefined, the context will typically be fetched from thread-local storage when calling the Perl API, which
incurs a performance overhead.
WARNING:
setting this macro involves additional changes to the XS code. For example, if the XS file has static functions that
call into the Perl API, you'll get somewhat cryptic error messages like the following:
/usr/lib/i386-linux-gnu/perl/5.20/CORE/perl.h:155:16: error: ‘my_perl’ undeclared (first use in this function)
# define aTHX my_perl
See http://perldoc.perl.org/perlguts.html#How-do-I-use-all-this-in-extensions? for ways in which to avoid these
errors when using the macro.
One way is to begin each static function that invoke the perl API with the dTHX macro to fetch context. This is
used in the following static functions.
Perl extension for efficient creation and manipulation of AVL balanced binary trees.
AVLTree provides a simple and fast implementation of AVL balanced trees.
It uses the Perl XS extension mechanism by providing a tiny wrapper around
an efficient C library which does the core of the work. Preliminary benchmarking
shows this module is one order of magnitude faster than a pure perl implementation.
The nodes of an AVL tree object can hold any kind of item, as long as each
one of these has an element which can be used to define a partial order on
the set of possible items. This is specified by providing, upon tree construction,
a reference to a function for comparing any two of the possible items.
The underlying C library is a reinterpretation of the C library originally
developed by Julienne Walker. This library has been adapted for dealing
directly with Perl (SV) variables.
INSTALLATION
To install this module, run the following commands:
lib/AVLTree.pm view on Meta::CPAN
=head1 DESCRIPTION
This module provides a simple and fast implementation of B<AVL balanced binary trees>.
It uses the Perl XS extension mechanism by providing a tiny wrapper around
an efficient C library which does the core of the work. Preliminary benchmarking
shows this module one order of magnitude faster than a pure perl implementation.
The nodes of an AVL tree object can hold any kind of item, as long as each
one of these can be used or has an element that can be use to define a partial order
on the set of possible items. This is specified by providing, upon tree construction,
a reference to a function for comparing any two of the possible items.
The underlying C library is a reinterpretation of the C library originally
developed by Julienne Walker L<http://www.eternallyconfuzzled.com/jsw_home.aspx>.
This library has been adapted for dealing directly with Perl (SV) variables.
The module at the moment is in beta stage but it is usable. It provides methods
for creating and querying an AVL tree, get its size and insert and remove elements
from it. Additionaly, it is possible to traverse the tree in forward/reverse order.
automagially add a dot between the original filename and the
suffix. If you want the dot, you have to include it in the option
argument.
If neither C<--patch> or C<--copy> are given, the default is to
simply print the diffs for each file. This requires either
C<Text::Diff> or a C<diff> program to be installed.
=head2 --diff=I<program>
Manually set the diff program and options to use. The default
is to use C<Text::Diff>, when installed, and output unified
context diffs.
=head2 --compat-version=I<version>
Tell F<ppport.h> to check for compatibility with the given
Perl version. The default is to check for compatibility with Perl
version 5.003. You can use this option to reduce the output
of F<ppport.h> if you intend to be backward compatible only
down to a certain Perl version.

To avoid namespace conflicts, you can change the namespace of the
explicitly exported functions / variables using the C<DPPP_NAMESPACE>
macro. Just C<#define> the macro before including C<ppport.h>:
#define DPPP_NAMESPACE MyOwnNamespace_
#include "ppport.h"
