## HOW TO CONTRIBUTE
Thank you for considering contributing to this distribution. This file
contains instructions that will help you work with the source code.
The distribution is managed with Dist::Zilla. This means than many of the
usual files you might expect are not in the repository, but are generated at
release time, as is much of the documentation. Some generated files are
kept in the repository as a convenience (e.g. Makefile.PL or cpanfile).
Generally, **you do not need Dist::Zilla to contribute patches**. You do need
Dist::Zilla to create a tarball. See below for guidance.
### Getting dependencies
If you have App::cpanminus 1.6 or later installed, you can use `cpanm` to
satisfy dependencies like this:
$ cpanm --installdeps .
Otherwise, look for either a `Makefile.PL` or `cpanfile` file for
a list of dependencies to satisfy.
### Running tests
You can run tests directly using the `prove` tool:
$ prove -l
$ prove -lv t/some_test_file.t
For most of my distributions, `prove` is entirely sufficient for you to test any
patches you have. I use `prove` for 99% of my testing during development.
### Code style and tidying
Please try to match any existing coding style. If there is a `.perltidyrc`
file, please install Perl::Tidy and use perltidy before submitting patches.
If there is a `tidyall.ini` file, you can also install Code::TidyAll and run
`tidyall` on a file or `tidyall -a` to tidy all files.
### Patching documentation
Much of the documentation Pod is generated at release time. Some is
generated boilerplate; other documentation is built from pseudo-POD
directives in the source like C<=method> or C<=func>.
If you would like to submit a documentation edit, please limit yourself to
the documentation you see.
If you see typos or documentation issues in the generated docs, please
email or open a bug ticket instead of patching.
### Installing and using Dist::Zilla
Dist::Zilla is a very powerful authoring tool, optimized for maintaining a
large number of distributions with a high degree of automation, but it has a
large dependency chain, a bit of a learning curve and requires a number of
author-specific plugins.
To install it from CPAN, I recommend one of the following approaches for
the quickest installation:
# using CPAN.pm, but bypassing non-functional pod tests
$ cpan TAP::Harness::Restricted
$ PERL_MM_USE_DEFAULT=1 HARNESS_CLASS=TAP::Harness::Restricted cpan Dist::Zilla
# using cpanm, bypassing *all* tests
$ cpanm -n Dist::Zilla
In either case, it's probably going to take about 10 minutes. Go for a walk,
go get a cup of your favorite beverage, take a bathroom break, or whatever.
When you get back, Dist::Zilla should be ready for you.
Then you need to install any plugins specific to this distribution:
$ cpan `dzil authordeps`
$ dzil authordeps | cpanm
Once installed, here are some dzil commands you might try:
$ dzil build
$ dzil test
$ dzil xtest
You can learn more about Dist::Zilla at http://dzil.org/

Software Foundation; either version 1, or (at your option) any
later version, or
b) the "Artistic License"
--- The GNU General Public License, Version 1, February 1989 ---

This is free software, licensed under:
The GNU General Public License, Version 1, February 1989
GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must tell them their rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
1. You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this General
Public License.
d) You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in
exchange for a fee.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 1 and 2 above provided that you also do one of the following:
a) accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying the Program (or any work based
on the Program) you indicate your acceptance of this license to do so,
and all its terms and conditions.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein.
7. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of the license which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
the license, you may choose any version ever published by the Free Software
Foundation.
8. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, or (at your option)
any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

This is free software, licensed under:
The Artistic License 1.0
The Artistic License
Preamble
The intent of this document is to state the conditions under which a Package
may be copied, such that the Copyright Holder maintains some semblance of
artistic control over the development of the package, while giving the users of
the package the right to use and distribute the Package in a more-or-less
customary fashion, plus the right to make reasonable modifications.
Definitions:
- "Package" refers to the collection of files distributed by the Copyright
Holder, and derivatives of that collection of files created through
textual modification.
- "Standard Version" refers to such a Package if it has not been modified,
or has been modified in accordance with the wishes of the Copyright
Holder.
- "Copyright Holder" is whoever is named in the copyright or copyrights for
the package.
- "You" is you, if you're thinking about copying or distributing this Package.
- "Reasonable copying fee" is whatever you can justify on the basis of media
cost, duplication charges, time of people involved, and so on. (You will
not be required to justify it to the Copyright Holder, but only to the
computing community at large as a market that must bear the fee.)
- "Freely Available" means that no fee is charged for the item itself, though
there may be fees involved in handling the item. It also means that
recipients of the item may redistribute it under the same conditions they
received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications derived
from the Public Domain or from the Copyright Holder. A Package modified in such
a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided that
you insert a prominent notice in each changed file stating how and when you
changed that file, and provided that you do at least ONE of the following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or an
equivalent medium, or placing the modifications on a major archive site
such as ftp.uu.net, or by allowing the Copyright Holder to include your
modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict with
standard executables, which must also be provided, and provide a separate
manual page for each non-standard executable that clearly documents how it
differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or executable
form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where to
get the Standard Version.
b) accompany the distribution with the machine-readable source of the Package
with your modifications.
c) accompany any non-standard executables with their corresponding Standard
Version executables, giving the non-standard executables non-standard
names, and clearly documenting the differences in manual pages (or
equivalent), together with instructions on where to get the Standard
Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this Package. You
may not charge a fee for this Package itself. However, you may distribute this
Package in aggregate with other (possibly commercial) programs as part of a
larger (possibly commercial) software distribution provided that you do not
advertise this Package as a product of your own.
6. The scripts and library files supplied as input to or produced as output
from the programs of this Package do not automatically fall under the copyright
of this Package, but belong to whomever generated them, and may be sold
commercially, and may be aggregated with this Package.
7. C or perl subroutines supplied by you and linked into this Package shall not
be considered part of this Package.
8. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

NAME
Sub::Uplevel - apparently run a function in a higher stack frame
VERSION
version 0.2800
SYNOPSIS
use Sub::Uplevel;
sub foo {
print join " - ", caller;
}
sub bar {
uplevel 1, \&foo;
}
#line 11
bar(); # main - foo.plx - 11
DESCRIPTION
Like Tcl's uplevel() function, but not quite so dangerous. The idea is
just to fool caller(). All the really naughty bits of Tcl's uplevel()
are avoided.
THIS IS NOT THE SORT OF THING YOU WANT TO DO EVERYDAY
uplevel
uplevel $num_frames, \&func, @args;
Makes the given function think it's being executed $num_frames
higher than the current stack level. So when they use
caller($frames) it will actually give caller($frames + $num_frames)
for them.
"uplevel(1, \&some_func, @_)" is effectively "goto &some_func" but
you don't immediately exit the current subroutine. So while you
can't do this:
sub wrapper {
print "Before\n";
goto &some_func;
print "After\n";
}
you can do this:
sub wrapper {
print "Before\n";
my @out = uplevel 1, &some_func;
print "After\n";
return @out;
}
"uplevel" has the ability to issue a warning if $num_frames is more
than the current call stack depth, although this warning is disabled
and compiled out by default as the check is relatively expensive.
To enable the check for debugging or testing, you should set the
global $Sub::Uplevel::CHECK_FRAMES to true before loading
Sub::Uplevel for the first time as follows:
#!/usr/bin/perl
BEGIN {
$Sub::Uplevel::CHECK_FRAMES = 1;
}
use Sub::Uplevel;
Setting or changing the global after the module has been loaded will
have no effect.
EXAMPLE
The main reason I wrote this module is so I could write wrappers around
functions and they wouldn't be aware they've been wrapped.
use Sub::Uplevel;
my $original_foo = \&foo;
*foo = sub {
my @output = uplevel 1, $original_foo;
print "foo() returned: @output";
return @output;
};
If this code frightens you you should not use this module.
BUGS and CAVEATS
Well, the bad news is uplevel() is about 5 times slower than a normal
function call. XS implementation anyone? It also slows down every
invocation of caller(), regardless of whether uplevel() is in effect.
Sub::Uplevel overrides CORE::GLOBAL::caller temporarily for the scope of
each uplevel call. It does its best to work with any previously existing
CORE::GLOBAL::caller (both when Sub::Uplevel is first loaded and within
each uplevel call) such as from Contextual::Return or Hook::LexWrap.
However, if you are routinely using multiple modules that override
CORE::GLOBAL::caller, you are probably asking for trouble.
You should load Sub::Uplevel as early as possible within your program.
As with all CORE::GLOBAL overloading, the overload will not affect
modules that have already been compiled prior to the overload. One
module that often is unavoidably loaded prior to Sub::Uplevel is
Exporter. To forcibly recompile Exporter (and Exporter::Heavy) after
loading Sub::Uplevel, use it with the ":aggressive" tag:
use Sub::Uplevel qw/:aggressive/;
The private function "Sub::Uplevel::_force_reload()" may be passed a
list of additional modules to reload if ":aggressive" is not aggressive
enough. Reloading modules may break things, so only use this as a last
resort.
As of version 0.20, Sub::Uplevel requires Perl 5.6 or greater.
HISTORY
Those who do not learn from HISTORY are doomed to repeat it.
The lesson here is simple: Don't sit next to a Tcl programmer at the
dinner table.

#pod winds up no or above uplevel(), it's CORE::caller(X+1+uplevel+1).

#pod call to uplevel (from the Up_Frames stack set during the uplevel call)
#pod
#pod * additionally, we need to hide the uplevel subroutine call, too, so we search
#pod upwards one more level for each call to uplevel
#pod
#pod * when we've reached the top of the search, we want to return that frame
#pod in the call stack, i.e. the requested height plus any uplevel adjustments

B<THIS IS NOT THE SORT OF THING YOU WANT TO DO EVERYDAY>
=over 4
=item B<uplevel>
uplevel $num_frames, \&func, @args;
Makes the given function think it's being executed $num_frames higher
than the current stack level. So when they use caller($frames) it
will actually give caller($frames + $num_frames) for them.
C<uplevel(1, \&some_func, @_)> is effectively C<goto &some_func> but
you don't immediately exit the current subroutine. So while you can't
do this:
sub wrapper {
print "Before\n";
goto &some_func;
print "After\n";
}
you can do this:
sub wrapper {
print "Before\n";
my @out = uplevel 1, &some_func;
print "After\n";
return @out;
}
C<uplevel> has the ability to issue a warning if C<$num_frames> is more than
the current call stack depth, although this warning is disabled and compiled
out by default as the check is relatively expensive.
To enable the check for debugging or testing, you should set the global
C<$Sub::Uplevel::CHECK_FRAMES> to true before loading Sub::Uplevel for the
first time as follows:
#!/usr/bin/perl
BEGIN {
$Sub::Uplevel::CHECK_FRAMES = 1;
}
use Sub::Uplevel;
Setting or changing the global after the module has been loaded will have
no effect.
=begin _private
So it has to work like this:
Call stack Actual uplevel 1
CORE::GLOBAL::caller
Carp::short_error_loc 0
Carp::shortmess_heavy 1 0
Carp::croak 2 1
try_croak 3 2
uplevel 4
function_that_called_uplevel 5
caller_we_want_to_see 6 3
its_caller 7 4
So when caller(X) winds up below uplevel(), it only has to use
CORE::caller(X+1) (to skip CORE::GLOBAL::caller). But when caller(X)
winds up no or above uplevel(), it's CORE::caller(X+1+uplevel+1).
Which means I'm probably going to have to do something nasty like walk
up the call stack on each caller() to see if I'm going to wind up
before or after Sub::Uplevel::uplevel().
=end _private
=begin _dagolden
I found the description above a bit confusing. Instead, this is the logic
that I found clearer when CORE::GLOBAL::caller is invoked and we have to
walk up the call stack:
* if searching up to the requested height in the real call stack doesn't find
a call to uplevel, then we can return the result at that height in the
call stack
* if we find a call to uplevel, we need to keep searching upwards beyond the
requested height at least by the amount of upleveling requested for that
call to uplevel (from the Up_Frames stack set during the uplevel call)
* additionally, we need to hide the uplevel subroutine call, too, so we search
upwards one more level for each call to uplevel
* when we've reached the top of the search, we want to return that frame
in the call stack, i.e. the requested height plus any uplevel adjustments
found during the search
=end _dagolden

=head1 EXAMPLE
The main reason I wrote this module is so I could write wrappers
around functions and they wouldn't be aware they've been wrapped.
use Sub::Uplevel;
my $original_foo = \&foo;
*foo = sub {
my @output = uplevel 1, $original_foo;
print "foo() returned: @output";
return @output;
};
If this code frightens you B<you should not use this module.>
=head1 BUGS and CAVEATS
Well, the bad news is uplevel() is about 5 times slower than a normal
function call. XS implementation anyone? It also slows down every invocation
of caller(), regardless of whether uplevel() is in effect.
Sub::Uplevel overrides CORE::GLOBAL::caller temporarily for the scope of
each uplevel call. It does its best to work with any previously existing
CORE::GLOBAL::caller (both when Sub::Uplevel is first loaded and within
each uplevel call) such as from Contextual::Return or Hook::LexWrap.
However, if you are routinely using multiple modules that override
CORE::GLOBAL::caller, you are probably asking for trouble.
You B<should> load Sub::Uplevel as early as possible within your program. As
with all CORE::GLOBAL overloading, the overload will not affect modules that
have already been compiled prior to the overload. One module that often is
unavoidably loaded prior to Sub::Uplevel is Exporter. To forcibly recompile
Exporter (and Exporter::Heavy) after loading Sub::Uplevel, use it with the
":aggressive" tag:
use Sub::Uplevel qw/:aggressive/;
The private function C<Sub::Uplevel::_force_reload()> may be passed a list of
additional modules to reload if ":aggressive" is not aggressive enough.
Reloading modules may break things, so only use this as a last resort.
As of version 0.20, Sub::Uplevel requires Perl 5.6 or greater.
=head1 HISTORY
Those who do not learn from HISTORY are doomed to repeat it.
The lesson here is simple: Don't sit next to a Tcl programmer at the
dinner table.
