=head1 NAME

cpan-changes - CLI for CPAN::Changes

=head1 VERSION

This document describes version 0.001 of cpan-changes (from Perl distribution App-CPAN-Changes), released on 2016-10-10.

=head1 SYNOPSIS

Check syntax:

 % cpan-changes check -f Changes
 % cpan-changes check ;# by default try to search file Changes, CHANGELOG, etc

Parse and dump parse result as JSON structure:

 % cpan-changes dump

Get preamble:

 % cpan-changes preamble

Set new preamble:

 % cpan-changes preamble "Revision history of Foo-Bar"

See information about a particular release:

 % cpan-changes release 0.001

Add a new release:

 % cpan-changes add-release 0.002 2016-10-10 "Change 1" "[GROUP 1]" "Change 2"

 # ditto, but dry-run and will show the resulting Changes file
 % cpan-changes add-release -V 0.002 --date 2016-10-10 --change "Change 1" \
     --change "[GROUP 1]" --change "Change 2" --dry-run

More subcommands to be added.

=head1 SUBCOMMANDS

=head2 B<add-release>

Add a new release.

=head2 B<check>

Check for parsing errors in Changes file.

=head2 B<dump>

Dump Changes as JSON structure.

=head2 B<preamble>

Get/set preamble.

=head2 B<release>

Return information (JSON object dump) of a specific release.

=head1 OPTIONS

C<*> marks required options.

=head2 Common options

=over

=item B<--config-path>=I<filename>

Set path to configuration file.

Can be specified multiple times.

=item B<--config-profile>=I<s>

Set configuration profile to use.

=item B<--file>=I<s>, B<-f>

If not specified, will look for file called Changes/CHANGELOG/etc in current directory.

=item B<--format>=I<s>

Choose output format, e.g. json, text.

Default value:

 undef

=item B<--help>, B<-h>, B<-?>

Display help message and exit.

=item B<--json>

Set output format to json.

=item B<--naked-res>

When outputing as JSON, strip result envelope.

Default value:

 0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
`--naked-res` so you just get:

    [1,2,3]


=item B<--no-config>

Do not use any configuration file.

=item B<--no-env>

Do not read environment for default options.

=item B<--subcommands>

List available subcommands.

=item B<--version>, B<-v>

Display program's version and exit.

=back

=head2 Options for subcommand add-release

=over

=item B<--change>=I<s@>*

Can be specified multiple times.

=item B<--changes-json>=I<s>

See C<--change>.

=item B<--date>=I<s>*

=item B<--note>=I<s>

=item B<--version-arg>=I<s>*, B<-V>

=back

=head2 Options for subcommand preamble

=over

=item B<--preamble>=I<s>

Set new preamble.

=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C cpan-changes cpan-changes

in your bash startup (e.g. C<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install L<shcompgen> which allows you to
activate completion scripts for several kinds of scripts on multiple shells.
Some CPAN distributions (those that are built with
L<Dist::Zilla::Plugin::GenShellCompletion>) will even automatically enable shell
completion for their included scripts (using C<shcompgen>) at installation time,
so you can immadiately have tab completion.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete cpan-changes 'p/*/`cpan-changes`/'

in your tcsh startup (e.g. C<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install C<shcompgen> (see above).

=head2 other shells

For fish and zsh, install C<shcompgen> as described above.

=head1 CONFIGURATION FILE

This script can read configuration files. Configuration files are in the format of L<IOD>, which is basically INI with some extra features.

By default, these names are searched for configuration filenames (can be changed using C<--config-path>): F<~/.config/cpan-changes.conf>, F<~/cpan-changes.conf>, or F</etc/cpan-changes.conf>.

All found files will be read and merged.

To disable searching for configuration files, pass C<--no-config>.

To put configuration for a certain subcommand only, use a section name like C<[subcommand=NAME]> or C<[SOMESECTION subcommand=NAME]>.

You can put multiple profiles in a single file by using section names like C<[profile=SOMENAME]> or C<[SOMESECTION profile=SOMENAME]> or C<[subcommand=SUBCOMMAND_NAME profile=SOMENAME]> or C<[SOMESECTION subcommand=SUBCOMMAND_NAME profile=SOMENAME]>. Those sections will only be read if you specify the matching C<--config-profile SOMENAME>.

You can also put configuration for multiple programs inside a single file, and use filter C<program=NAME> in section names, e.g. C<[program=NAME ...]> or C<[SOMESECTION program=NAME]>. The section will then only be used when the reading program matches.

Finally, you can filter a section by environment variable using the filter C<env=CONDITION> in section names. For example if you only want a section to be read if a certain environment variable is true: C<[env=SOMEVAR ...]> or C<[SOMESECTION env=SOMEVAR ...]>. If you only want a section to be read when the value of an environment variable has value equals something: C<[env=HOSTNAME=blink ...]> or C<[SOMESECTION env=HOSTNAME=blink ...]>. If you only want a section to be read when the value of an environment variable does not equal something: C<[env=HOSTNAME!=blink ...]> or C<[SOMESECTION env=HOSTNAME!=blink ...]>. If you only want a section to be read when an environment variable contains something: C<[env=HOSTNAME*=server ...]> or C<[SOMESECTION env=HOSTNAME*=server ...]>. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.

#   quotes and backslashes);
#
#2) quoted phrase that contain spaces, or phrase that contains escaped spaces is
#   parsed as a single word. For example:
#
#    command "First argument" Second\ argument
#
#   bash would split it as (represented as Perl):
#
#    ["command", "\"First", "argument\"", "Second\\", "argument"]
#
#   which is not very convenient. We parse it into:
#
#    ["command", "First argument", "Second argument"]
#
#3) variables are substituted with their values from environment variables except
#   for the current word (`COMP_WORDS[COMP_CWORD]`) (bash does not perform
#   variable substitution for `COMP_WORDS`). However, note that special shell
#   variables that are not environment variables like `$0`, `$_`, `$IFS` will not
#   be replaced correctly because bash does not export those variables for us.
#
#4) tildes (`~`) are expanded with user's home directory except for the current
#   word (bash does not perform tilde expansion for `COMP_WORDS`);
#
#Caveats:
#
#* Like bash, we group non-whitespace word-breaking characters into its own word.
#  By default `COMP_WORDBREAKS` is:
#
#    "'@><=;|&(:
#
#  So if raw command-line is:
#
#    command --foo=bar http://example.com:80 mail@example.org Foo::Bar
#
#  then the parse result will be:
#
#    ["command", "--foo", "=", "bar", "http", ":", "//example.com", ":", "80", "Foo", "::", "Bar"]
#
#  which is annoying sometimes. But we follow bash here so we can more easily
#  accept input from a joined `COMP_WORDS` if we write completion bash functions,
#  e.g. (in the example, `foo` is a Perl script):
#
#    _foo ()
#    {
#        local words=(${COMP_CWORDS[@]})
#        # add things to words, etc
#        local point=... # calculate the new point
#        COMPREPLY=( `COMP_LINE="foo ${words[@]}" COMP_POINT=$point foo` )
#    }
#
#  To avoid these word-breaking characters to be split/grouped, we can escape
#  them with backslash or quote them, e.g.:
#
#    command "http://example.com:80" Foo\:\:Bar
#
#  which bash will parse as:
#
#    ["command", "\"http://example.com:80\"", "Foo\\:\\:Bar"]
#
#  and we parse as:
#
#    ["command", "http://example.com:80", "Foo::Bar"]
#
#* Due to the way bash parses the command line (see above), the two below are
#  equivalent:
#
#    % cmd --foo=bar
#    % cmd --foo = bar
#
#Because they both expand to `['--foo', '=', 'bar']`. But obviously
#<pm:Getopt::Long> does not regard the two as equivalent.

#
#Bash accepts completion reply in the form of one entry per line to STDOUT. Some
#characters will need to be escaped. This function helps you do the formatting,
#with some options.
#
#This function accepts completion answer structure as described in the `Complete`
#POD. Aside from `words`, this function also recognizes these keys:
#
#* `as` (str): Either `string` (the default) or `array` (to return array of lines
#  instead of the lines joined together). Returning array is useful if you are
#  doing completion inside `Term::ReadLine`, for example, where the library
#  expects an array.
#
#* `esc_mode` (str): Escaping mode for entries. Either `default` (most
#  nonalphanumeric characters will be escaped), `shellvar` (like `default`, but
#  dollar sign `$` will not be escaped, convenient when completing environment
#  variables for example), `filename` (currently equals to `default`), `option`
#  (currently equals to `default`), or `none` (no escaping will be done).
#
#* `path_sep` (str): If set, will enable "path mode", useful for
#  completing/drilling-down path. Below is the description of "path mode".
#
#  In shell, when completing filename (e.g. `foo`) and there is only a single
#  possible completion (e.g. `foo` or `foo.txt`), the shell will display the
#  completion in the buffer and automatically add a space so the user can move to
#  the next argument. This is also true when completing other values like
#  variables or program names.
#
#  However, when completing directory (e.g. `/et` or `Downloads`) and there is
#  solely a single completion possible and it is a directory (e.g. `/etc` or
#  `Downloads`), the shell automatically adds the path separator character
#  instead (`/etc/` or `Downloads/`). The user can press Tab again to complete
#  for files/directories inside that directory, and so on. This is obviously more
#  convenient compared to when shell adds a space instead.
#
#  The `path_sep` option, when set, will employ a trick to mimic this behaviour.
#  The trick is, if you have a completion array of `['foo/']`, it will be changed
#  to `['foo/', 'foo/ ']` (the second element is the first element with added
#  space at the end) to prevent bash from adding a space automatically.
#
#  Path mode is not restricted to completing filesystem paths. Anything path-like
#  can use it. For example when you are completing Java or Perl module name (e.g.
#  `com.company.product.whatever` or `File::Spec::Unix`) you can use this mode
#  (with `path_sep` appropriately set to, e.g. `.` or `::`).

#* `parsed_opts` (hash, options parsed the standard/raw way)
#
#as well as all keys from `extras` (but these won't override the above keys).
#
#and is expected to return a completion answer structure as described in
#`Complete` which is either a hash or an array. The simplest form of answer is
#just to return an array of strings. The various `complete_*` function like those

#JSON - JSON (JavaScript Object Notation) encoder/decoder
#
#=head1 SYNOPSIS
#
# use JSON; # imports encode_json, decode_json, to_json and from_json.
# 
# # simple and fast interfaces (expect/generate UTF-8)
# 
# $utf8_encoded_json_text = encode_json $perl_hash_or_arrayref;
# $perl_hash_or_arrayref  = decode_json $utf8_encoded_json_text;
# 
# # OO-interface

# $json = JSON->new->allow_nonref;
# 
# $json_text   = $json->encode( $perl_scalar );
# $perl_scalar = $json->decode( $json_text );
# 
# $pretty_printed = $json->pretty->encode( $perl_scalar ); # pretty-printing
# 
# # If you want to use PP only support features, call with '-support_by_pp'
# # When XS unsupported feature is enable, using PP (de|en)code instead of XS ones.
# 
# use JSON -support_by_pp;
# 
# # option-acceptable interfaces (expect/generate UNICODE by default)
# 
# $json_text   = to_json( $perl_scalar, { ascii => 1, pretty => 1 } );
# $perl_scalar = from_json( $json_text, { utf8  => 1 } );
# 
# # Between (en|de)code_json and (to|from)_json, if you want to write
# # a code which communicates to an outer world (encoded in UTF-8),
# # recommend to use (en|de)code_json.
# 
#=head1 VERSION
#
#    2.90
#
#This version is compatible with JSON::XS B<2.34> and later.
#(Not yet compatble to JSON::XS B<3.0x>.)
#
#
#=head1 NOTE
#
#JSON::PP was earlier included in the C<JSON> distribution, but
#has since Perl 5.14 been a core module. For this reason,
#L<JSON::PP> was removed from the JSON distribution and can now
#be found also in the Perl5 repository at
#
#=over
#
#=item * L<http://perl5.git.perl.org/perl.git>
#
#=back
#
#(The newest JSON::PP version still exists in CPAN.)
#
#Instead, the C<JSON> distribution will include JSON::backportPP
#for backwards computability. JSON.pm should thus work as it did
#before.

# *************************** CAUTION **************************************
# *                                                                        *
# * INCOMPATIBLE CHANGE (JSON::XS version 2.90)                            *
# *                                                                        *
# * JSON.pm had patched JSON::XS::Boolean and JSON::PP::Boolean internally *
# * on loading time for making these modules inherit JSON::Boolean.        *
# * But since JSON::XS v3.0 it use Types::Serialiser as boolean class.     *
# * Then now JSON.pm breaks boolean classe overload features and           *
# * -support_by_pp if JSON::XS v3.0 or later is installed.                 *
# *                                                                        *
# * JSON::true and JSON::false returned JSON::Boolean objects.             *
# * For workaround, they return JSON::PP::Boolean objects in this version. *
# *                                                                        *

# *                                                                        *
# * And it discards a feature:                                             *
# *                                                                        *

# * In other word, JSON::PP::Boolean overload numeric only.                *
# *                                                                        *

#
#JSON (JavaScript Object Notation) is a simple data format.
#See to L<http://www.json.org/> and C<RFC4627>(L<http://www.ietf.org/rfc/rfc4627.txt>).
#
#This module converts Perl data structures to JSON and vice versa using either
#L<JSON::XS> or L<JSON::PP>.
#
#JSON::XS is the fastest and most proper JSON module on CPAN which must be
#compiled and installed in your environment.
#JSON::PP is a pure-Perl module which is bundled in this distribution and
#has a strong compatibility to JSON::XS.
#
#This module try to use JSON::XS by default and fail to it, use JSON::PP instead.
#So its features completely depend on JSON::XS or JSON::PP.
#
#See to L<BACKEND MODULE DECISION>.
#
#To distinguish the module name 'JSON' and the format type JSON,
#the former is quoted by CE<lt>E<gt> (its results vary with your using media),
#and the latter is left just as it is.
#
#Module name : C<JSON>
#
#Format type : JSON
#
#=head2 FEATURES
#
#=over
#
#=item * correct unicode handling
#
#This module (i.e. backend modules) knows how to handle Unicode, documents
#how and when it does so, and even documents what "correct" means.
#
#Even though there are limitations, this feature is available since Perl version 5.6.
#
#JSON::XS requires Perl 5.8.2 (but works correctly in 5.8.8 or later), so in older versions
#C<JSON> should call JSON::PP as the backend which can be used since Perl 5.005.
#
#With Perl 5.8.x JSON::PP works, but from 5.8.0 to 5.8.2, because of a Perl side problem,
#JSON::PP works slower in the versions. And in 5.005, the Unicode handling is not available.
#See to L<JSON::PP/UNICODE HANDLING ON PERLS> for more information.
#
#See also to L<JSON::XS/A FEW NOTES ON UNICODE AND PERL>
#and L<JSON::XS/ENCODING/CODESET_FLAG_NOTES>.
#
#
#=item * round-trip integrity
#
#When you serialise a perl data structure using only data types supported
#by JSON and Perl, the deserialised data structure is identical on the Perl
#level. (e.g. the string "2.0" doesn't suddenly become "2" just because
#it looks like a number). There I<are> minor exceptions to this, read the
#L</MAPPING> section below to learn about those.
#
#
#=item * strict checking of JSON correctness
#
#There is no guessing, no generating of illegal JSON texts by default,
#and only JSON is accepted as input by default (the latter is a security
#feature).
#
#See to L<JSON::XS/FEATURES> and L<JSON::PP/FEATURES>.
#
#=item * fast
#
#This module returns a JSON::XS object itself if available.
#Compared to other JSON modules and other serialisers such as Storable,
#JSON::XS usually compares favorably in terms of speed, too.
#
#If not available, C<JSON> returns a JSON::PP object instead of JSON::XS and
#it is very slow as pure-Perl.
#
#=item * simple to use
#
#This module has both a simple functional interface as well as an
#object oriented interface interface.
#
#=item * reasonably versatile output formats
#
#You can choose between the most compact guaranteed-single-line format possible
#(nice for simple line-based protocols), a pure-ASCII format (for when your transport
#is not 8-bit clean, still supports the whole Unicode range), or a pretty-printed
#format (for when you want to read that stuff). Or you can combine those features
#in whatever way you like.
#
#=back
#
#=head1 FUNCTIONAL INTERFACE
#
#Some documents are copied and modified from L<JSON::XS/FUNCTIONAL INTERFACE>.
#C<to_json> and C<from_json> are additional functions.
#
#=head2 encode_json
#
#    $json_text = encode_json $perl_scalar
#
#Converts the given Perl data structure to a UTF-8 encoded, binary string.
#
#This function call is functionally identical to:
#
#    $json_text = JSON->new->utf8->encode($perl_scalar)
#
#=head2 decode_json
#
#    $perl_scalar = decode_json $json_text
#
#The opposite of C<encode_json>: expects an UTF-8 (binary) string and tries
#to parse that as an UTF-8 encoded JSON text, returning the resulting
#reference.
#
#This function call is functionally identical to:
#
#    $perl_scalar = JSON->new->utf8->decode($json_text)
#
#
#=head2 to_json
#
#   $json_text = to_json($perl_scalar)
#
#Converts the given Perl data structure to a json string.
#
#This function call is functionally identical to:
#
#   $json_text = JSON->new->encode($perl_scalar)
#
#Takes a hash reference as the second.
#
#   $json_text = to_json($perl_scalar, $flag_hashref)
#
#So,
#
#   $json_text = to_json($perl_scalar, {utf8 => 1, pretty => 1})
#
#equivalent to:
#
#   $json_text = JSON->new->utf8(1)->pretty(1)->encode($perl_scalar)
#
#If you want to write a modern perl code which communicates to outer world,
#you should use C<encode_json> (supposed that JSON data are encoded in UTF-8).
#
#=head2 from_json
#
#   $perl_scalar = from_json($json_text)
#
#The opposite of C<to_json>: expects a json string and tries
#to parse it, returning the resulting reference.
#
#This function call is functionally identical to:
#
#    $perl_scalar = JSON->decode($json_text)
#
#Takes a hash reference as the second.
#
#    $perl_scalar = from_json($json_text, $flag_hashref)
#
#So,
#
#    $perl_scalar = from_json($json_text, {utf8 => 1})
#
#equivalent to:
#
#    $perl_scalar = JSON->new->utf8(1)->decode($json_text)
#
#If you want to write a modern perl code which communicates to outer world,
#you should use C<decode_json> (supposed that JSON data are encoded in UTF-8).
#
#=head2 JSON::is_bool
#
#    $is_boolean = JSON::is_bool($scalar)
#
#Returns true if the passed scalar represents either JSON::true or
#JSON::false, two constants that act like C<1> and C<0> respectively
#and are also used to represent JSON C<true> and C<false> in Perl strings.
#
#=head2 JSON::true
#
#Returns JSON true value which is blessed object.
#It C<isa> JSON::Boolean object.
#
#=head2 JSON::false
#
#Returns JSON false value which is blessed object.
#It C<isa> JSON::Boolean object.
#
#=head2 JSON::null
#
#Returns C<undef>.
#
#See L<MAPPING>, below, for more information on how JSON values are mapped to
#Perl.
#
#=head1 HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER
#
#This section supposes that your perl version is 5.8 or later.

#If you know a JSON text from an outer world - a network, a file content, and so on,
#is encoded in UTF-8, you should use C<decode_json> or C<JSON> module object
#with C<utf8> enable. And the decoded result will contain UNICODE characters.

#  # open( my $fh, "<:encoding($encoding)", 'json.data' );
#  # $unicode_json_text = <$fh>;
#
#In this case, C<$unicode_json_text> is of course UNICODE string.
#So you B<cannot> use C<decode_json> nor C<JSON> module object with C<utf8> enable.
#Instead of them, you use C<JSON> module object with C<utf8> disable or C<from_json>.

#Or C<encode 'utf8'> and C<decode_json>:
#
#  $perl_scalar = decode_json( encode( 'utf8', $unicode_json_text ) );
#  # this way is not efficient.
#
#And now, you want to convert your C<$perl_scalar> into JSON data and
#send it to an outer world - a network or a file content, and so on.
#
#Your data usually contains UNICODE strings and you want the converted data to be encoded
#in UTF-8, you should use C<encode_json> or C<JSON> module object with C<utf8> enable.
#
#  print encode_json( $perl_scalar ); # to a network? file? or display?
#  # or
#  print $json->utf8->encode( $perl_scalar );
#
#If C<$perl_scalar> does not contain UNICODE but C<$encoding>-encoded strings
#for some reason, then its characters are regarded as B<latin1> for perl
#(because it does not concern with your $encoding).
#You B<cannot> use C<encode_json> nor C<JSON> module object with C<utf8> enable.
#Instead of them, you use C<JSON> module object with C<utf8> disable or C<to_json>.
#Note that the resulted text is a UNICODE string but no problem to print it.
#
#  # $perl_scalar contains $encoding encoded string values
#  $unicode_json_text = $json->utf8(0)->encode( $perl_scalar );
#  # or 
#  $unicode_json_text = to_json( $perl_scalar );
#  # $unicode_json_text consists of characters less than 0x100
#  print $unicode_json_text;
#
#Or C<decode $encoding> all string values and C<encode_json>:
#
#  $perl_scalar->{ foo } = decode( $encoding, $perl_scalar->{ foo } );
#  # ... do it to each string values, then encode_json
#  $json_text = encode_json( $perl_scalar );

#If $enable is false, then the encode method will return the JSON string as a (non-encoded)
#Unicode string, while decode expects thus a Unicode string. Any decoding or encoding
#(e.g. to UTF-8 or UTF-16) needs to be done yourself, e.g. using the Encode module.

#
#Currently accepted extensions are:
#
#=over 4
#
#=item * list items can have an end-comma
#
#JSON I<separates> array elements and key-value pairs with commas. This
#can be annoying if you write JSON texts manually and want to be able to
#quickly append elements, so this extension accepts comma at the end of

#Whenever JSON allows whitespace, shell-style comments are additionally
#allowed. They are terminated by the first carriage-return or line-feed
#character, after which more white-space and comments are allowed.

#If C<$enable> is true (or missing), then the C<encode> method will output JSON objects

#
#If C<$enable> is false, then the C<encode> method will output key-value
#pairs in the order Perl stores them (which will likely change between runs

#
#This option is useful if you want the same data structure to be encoded as

#
#If C<$enable> is true (or missing), then the C<encode> method can convert a
#non-reference into its corresponding string, number or null JSON value,
#which is an extension to RFC4627. Likewise, C<decode> will accept those JSON
#values instead of croaking.
#
#If C<$enable> is false, then the C<encode> method will croak if it isn't

#    
#    $enabled = $json->get_allow_blessed
#
#If C<$enable> is true (or missing), then the C<encode> method will not
#barf when it encounters a blessed reference. Instead, the value of the
#B<convert_blessed> option will decide whether C<null> (C<convert_blessed>

#    $json = $json->convert_blessed([$enable])
#    
#    $enabled = $json->get_convert_blessed
#
#If C<$enable> is true (or missing), then C<encode>, upon encountering a
#blessed object, will check for the availability of the C<TO_JSON> method
#on the object's class. If found, it will be called in scalar context
#and the resulting scalar will be encoded instead of the object. If no
#C<TO_JSON> method is found, the value of C<allow_blessed> will decide what
#to do.
#
#The C<TO_JSON> method may safely call die if it wants. If C<TO_JSON>
#returns other blessed objects, those will be handled in the same
#way. C<TO_JSON> must take care of not causing an endless recursion cycle
#(== crash) in this case. The name of C<TO_JSON> was chosen because other
#methods called by the Perl core (== not by the user of the object) are
#usually in upper case letters and to avoid collisions with the C<to_json>
#function or method.
#
#This setting does not yet influence C<decode> in any way.

#
#=head2 filter_json_object
#
#    $json = $json->filter_json_object([$coderef])
#
#When C<$coderef> is specified, it will be called from C<decode> each
#time it decodes a JSON object. The only argument passed to the coderef
#is a reference to the newly-created hash. If the code references returns
#a single scalar (which need not be a reference), this value
#(i.e. a copy of that scalar to avoid aliasing) is inserted into the
#deserialised data structure. If it returns an empty list
#(NOTE: I<not> C<undef>, which is a valid scalar), the original deserialised
#hash will be inserted. This setting can slow down decoding considerably.
#
#When C<$coderef> is omitted or undefined, any existing callback will
#be removed and C<decode> will not change the deserialised hash in any
#way.
#
#Example, convert all JSON objects into the integer 5:
#
#   my $js = JSON->new->filter_json_object (sub { 5 });
#   # returns [5]
#   $js->decode ('[{}]'); # the given subroutine takes a hash reference.
#   # throw an exception because allow_nonref is not enabled
#   # so a lone 5 is not allowed.
#   $js->decode ('{"a":1, "b":2}');
#
#
#=head2 filter_json_single_key_object
#
#    $json = $json->filter_json_single_key_object($key [=> $coderef])
#
#Works remotely similar to C<filter_json_object>, but is only called for
#JSON objects having a single key named C<$key>.
#
#This C<$coderef> is called before the one specified via
#C<filter_json_object>, if any. It gets passed the single value in the JSON
#object. If it returns a single value, it will be inserted into the data
#structure. If it returns nothing (not even C<undef> but the empty list),
#the callback from C<filter_json_object> will be called next, as if no
#single-key callback were specified.
#
#If C<$coderef> is omitted or undefined, the corresponding callback will be
#disabled. There can only ever be one callback for a given key.
#
#As this callback gets called less often then the C<filter_json_object>
#one, decoding speed will not usually suffer as much. Therefore, single-key
#objects make excellent targets to serialise Perl objects into, especially
#as single-key JSON objects are as close to the type-tagged value concept
#as JSON gets (it's basically an ID/VALUE tuple). Of course, JSON does not
#support this in any way, so you need to make sure your data never looks
#like a serialised Perl hash.
#
#Typical names for the single object key are C<__class_whatever__>, or
#C<$__dollars_are_rarely_used__$> or C<}ugly_brace_placement>, or even
#things like C<__class_md5sum(classname)__>, to reduce the risk of clashing
#with real hashes.
#
#Example, decode JSON objects of the form C<< { "__widget__" => <id> } >>
#into the corresponding C<< $WIDGET{<id>} >> object:
#
#   # return whatever is in $WIDGET{5}:
#   JSON
#      ->new
#      ->filter_json_single_key_object (__widget__ => sub {
#            $WIDGET{ $_[0] }
#         })
#      ->decode ('{"__widget__": 5')
#
#   # this can be used with a TO_JSON method in some "widget" class
#   # for serialisation to json:
#   sub WidgetBase::TO_JSON {
#      my ($self) = @_;
#
#      unless ($self->{id}) {
#         $self->{id} = ..get..some..id..;

#With JSON::XS, this flag resizes strings generated by either

#memory when your JSON texts are either very very long or you have many
#short strings. It will also try to downgrade any strings to octet-form
#if possible: perl stores strings internally either in an encoding called
#UTF-X or in octet-form. The latter cannot store everything but uses less
#space in general (and some buggy Perl or C code might even rely on that
#internal representation being used).
#
#With JSON::PP, it is noop about resizing strings but tries

#Sets the maximum nesting level (default C<512>) accepted while encoding
#or decoding. If a higher nesting level is detected in JSON text or a Perl

#Nesting level is defined by number of hash- or arrayrefs that the encoder

#If no argument is given, the highest possible setting will be used, which

#=head1 INCREMENTAL PARSING
#
#Most of this section are copied and modified from L<JSON::XS/INCREMENTAL PARSING>.
#
#In some cases, there is the need for incremental parsing of JSON texts.
#This module does allow you to parse a JSON stream incrementally.
#It does so by accumulating text until it has a full JSON object, which
#it then can decode. This process is similar to using C<decode_prefix>
#to see if a full JSON object is available, but is much more efficient
#(and can be implemented with a minimum of method calls).
#
#The backend module will only attempt to parse the JSON text once it is sure it
#has enough text to get a decisive result, using a very simple but
#truly incremental parser. This means that it sometimes won't stop as
#early as the full parser, for example, it doesn't detect parenthesis
#mismatches. The only thing it guarantees is that it starts decoding as
#soon as a syntactically valid JSON text has been seen. This means you need
#to set resource limits (e.g. C<max_size>) to ensure the parser will stop
#parsing in the presence if syntax errors.
#
#The following methods implement this incremental parser.
#
#=head2 incr_parse

#This is the central parsing function. It can both append new text and
#extract objects from the stream accumulated so far (both of these
#functions are optional).
#
#If C<$string> is given, then this string is appended to the already
#existing JSON fragment stored in the C<$json> object.
#
#After that, if the function is called in void context, it will simply
#return without doing anything further. This can be used to add more text
#in as many chunks as you want.
#
#If the method is called in scalar context, then it will try to extract
#exactly I<one> JSON object. If that is successful, it will return this
#object, otherwise it will return C<undef>. If there is a parse error,
#this method will croak just as C<decode> would do (one can then use
#C<incr_skip> to skip the erroneous part). This is the most common way of
#using the method.
#
#And finally, in list context, it will try to extract as many objects
#from the stream as it can find and return them, or the empty list
#otherwise. For this to work, there must be no separators between the JSON
#objects or arrays, instead they must be concatenated back-to-back. If
#an error occurs, an exception will be raised as in the scalar context
#case. Note that in this case, any previously-parsed JSON texts will be
#lost.
#
#Example: Parse some JSON arrays/objects in a given string and return them.
#
#    my @objs = JSON->new->incr_parse ("[5][7][1,2]");
#
#=head2 incr_text
#
#    $lvalue_string = $json->incr_text
#
#This method returns the currently stored JSON fragment as an lvalue, that
#is, you can manipulate it. This I<only> works when a preceding call to
#C<incr_parse> in I<scalar context> successfully returned an object. Under
#all other circumstances you must not call this function (I mean it.
#although in simple tests it might actually work, it I<will> fail under
#real world conditions). As a special exception, you can also call this
#method before having parsed anything.
#
#This function is useful in two cases: a) finding the trailing text after a
#JSON object or b) parsing multiple JSON objects separated by non-JSON text
#(such as commas).
#
#    $json->incr_text =~ s/\s*,\s*//;
#
#In Perl 5.005, C<lvalue> attribute is not available.
#You must write codes like the below:
#
#    $string = $json->incr_text;
#    $string =~ s/\s*,\s*//;
#    $json->incr_text( $string );
#
#=head2 incr_skip
#
#    $json->incr_skip
#
#This will reset the state of the incremental parser and will remove the
#parsed text from the input buffer. This is useful after C<incr_parse>
#died, in which case the input buffer and incremental parser state is left
#unchanged, to skip the text parsed so far and to reset the parse state.
#
#=head2 incr_reset
#
#    $json->incr_reset
#
#This completely resets the incremental parser, that is, after this call,
#it will be as if the parser had never parsed anything.
#
#This is useful if you want to repeatedly parse JSON objects and want to
#ignore any trailing data, which means you have to reset the parser after
#each successful decode.
#

#
#=head2 allow_bignum
#
#    $json = $json->allow_bignum([$enable])
#
#If C<$enable> is true (or missing), then C<decode> will convert
#the big integer Perl cannot handle as integer into a L<Math::BigInt>
#object and convert a floating number (any) into a L<Math::BigFloat>.
#
#On the contrary, C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>

#See to L<JSON::PP/JSON::PP OWN METHODS>.
#
#=head1 MAPPING
#
#This section is copied from JSON::XS and modified to C<JSON>.
#JSON::XS and JSON::PP mapping mechanisms are almost equivalent.
#
#See to L<JSON::XS/MAPPING>.
#
#=head2 JSON -> PERL
#
#=over 4
#
#=item object
#
#A JSON object becomes a reference to a hash in Perl. No ordering of object
#keys is preserved (JSON does not preserver object key ordering itself).
#
#=item array
#
#A JSON array becomes a reference to an array in Perl.
#
#=item string
#
#A JSON string becomes a string scalar in Perl - Unicode codepoints in JSON
#are represented by the same codepoints in the Perl string, so no manual
#decoding is necessary.
#
#=item number
#
#A JSON number becomes either an integer, numeric (floating point) or
#string scalar in perl, depending on its range and any fractional parts. On
#the Perl level, there is no difference between those as Perl handles all
#the conversion details, but an integer may take slightly less memory and
#might represent more values exactly than floating point numbers.
#
#If the number consists of digits only, C<JSON> will try to represent
#it as an integer value. If that fails, it will try to represent it as
#a numeric (floating point) value if that is possible without loss of
#precision. Otherwise it will preserve the number as a string value (in
#which case you lose roundtripping ability, as the JSON number will be
#re-encoded to a JSON string).
#
#Numbers containing a fractional or exponential part will always be
#represented as numeric (floating point) values, possibly at a loss of
#precision (in which case you might lose perfect roundtripping ability, but
#the JSON number will still be re-encoded as a JSON number).
#
#Note that precision is not accuracy - binary floating point values cannot
#represent most decimal fractions exactly, and when converting from and to
#floating point, C<JSON> only guarantees precision up to but not including
#the least significant bit.
#
#If the backend is JSON::PP and C<allow_bignum> is enable, the big integers 
#and the numeric can be optionally converted into L<Math::BigInt> and
#L<Math::BigFloat> objects.
#
#=item true, false
#
#These JSON atoms become C<JSON::true> and C<JSON::false>,
#respectively. They are overloaded to act almost exactly like the numbers
#C<1> and C<0>. You can check whether a scalar is a JSON boolean by using
#the C<JSON::is_bool> function.
#
#   print JSON::true + 1;
#    => 1
#
#   ok(JSON::true eq  '1');
#   ok(JSON::true == 1);
#
#C<JSON> will install these missing overloading features to the backend modules.
#
#
#=item null
#
#A JSON null atom becomes C<undef> in Perl.
#
#C<JSON::null> returns C<undef>.
#
#=back
#
#
#=head2 PERL -> JSON
#
#The mapping from Perl to JSON is slightly more difficult, as Perl is a
#truly typeless language, so we can only guess which JSON type is meant by
#a Perl value.
#
#=over 4
#
#=item hash references
#
#Perl hash references become JSON objects. As there is no inherent ordering
#in hash keys (or JSON objects), they will usually be encoded in a
#pseudo-random order that can change between runs of the same program but
#stays generally the same within a single run of a program. C<JSON>
#optionally sort the hash keys (determined by the I<canonical> flag), so
#the same data structure will serialise to the same JSON text (given same
#settings and version of JSON::XS), but this incurs a runtime overhead
#and is only rarely useful, e.g. when you want to compare some JSON text
#against another for equality.
#
#In future, the ordered object feature will be added to JSON::PP using C<tie> mechanism.
#
#
#=item array references
#
#Perl array references become JSON arrays.
#
#=item other references
#
#Other unblessed references are generally not allowed and will cause an
#exception to be thrown, except for references to the integers C<0> and
#C<1>, which get turned into C<false> and C<true> atoms in JSON. You can
#also use C<JSON::false> and C<JSON::true> to improve readability.
#
#   to_json [\0,JSON::true]      # yields [false,true]
#
#=item JSON::true, JSON::false, JSON::null
#
#These special values become JSON true and JSON false values,
#respectively. You can also use C<\1> and C<\0> directly if you want.
#
#JSON::null returns C<undef>.
#
#=item blessed objects
#
#Blessed objects are not directly representable in JSON. See the
#C<allow_blessed> and C<convert_blessed> methods on various options on
#how to deal with this: basically, you can choose between throwing an
#exception, encoding the reference as if it weren't blessed, or provide
#your own serialiser method.
#
#With C<convert_blessed_universally> mode,  C<encode> converts blessed
#hash references or blessed array references (contains other blessed references)
#into JSON members and arrays.
#
#   use JSON -convert_blessed_universally;
#   JSON->new->allow_blessed->convert_blessed->encode( $blessed_object );
#
#See to L<convert_blessed>.
#
#=item simple scalars
#
#Simple Perl scalars (any scalar that is not a reference) are the most
#difficult objects to encode: JSON::XS and JSON::PP will encode undefined scalars as
#JSON C<null> values, scalars that have last been used in a string context
#before encoding as JSON strings, and anything else as number value:
#
#   # dump as number
#   encode_json [2]                      # yields [2]
#   encode_json [-3.0e17]                # yields [-3e+17]
#   my $value = 5; encode_json [$value]  # yields [5]
#
#   # used as string, so dump as string
#   print $value;
#   encode_json [$value]                 # yields ["5"]
#
#   # undef becomes null
#   encode_json [undef]                  # yields [null]
#
#You can force the type to be a string by stringifying it:
#
#   my $x = 3.1; # some variable containing a number
#   "$x";        # stringified
#   $x .= "";    # another, more awkward way to stringify
#   print $x;    # perl does it for you, too, quite often
#
#You can force the type to be a number by numifying it:
#
#   my $x = "3"; # some variable containing a string
#   $x += 0;     # numify it, ensuring it will be dumped as a number
#   $x *= 1;     # same thing, the choice is yours.
#
#You can not currently force the type in other, less obscure, ways.
#
#Note that numerical precision has the same meaning as under Perl (so
#binary to decimal conversion follows the same rules as in Perl, which
#can differ to other languages). Also, your perl interpreter might expose
#extensions to the floating point numbers of your platform, such as
#infinities or NaN's - these cannot be represented in JSON, and it is an
#error to pass those in.
#
#=item Big Number
#
#If the backend is JSON::PP and C<allow_bignum> is enable, 
#C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>
#objects into JSON numbers.

#
#=head1 BACKEND MODULE DECISION
#
#When you use C<JSON>, C<JSON> tries to C<use> JSON::XS. If this call failed, it will
#C<uses> JSON::PP. The required JSON::XS version is I<2.2> or later.
#
#The C<JSON> constructor method returns an object inherited from the backend module,
#and JSON::XS object is a blessed scalar reference while JSON::PP is a blessed hash
#reference.
#
#So, your program should not depend on the backend module, especially
#returned objects should not be modified.
#
# my $json = JSON->new; # XS or PP?
# $json->{stash} = 'this is xs object'; # this code may raise an error!
#
#To check the backend module, there are some methods - C<backend>, C<is_pp> and C<is_xs>.
#
#  JSON->backend; # 'JSON::XS' or 'JSON::PP'

#
#Always use JSON::backportPP.
#JSON::backportPP is JSON::PP back port module.
#C<JSON> includes JSON::backportPP instead of JSON::PP.

#
#These ideas come from L<DBI::PurePerl> mechanism.
#
#example:
#
# BEGIN { $ENV{PERL_JSON_BACKEND} = 'JSON::PP' }
# use JSON; # always uses JSON::PP
#
#In future, it may be able to specify another module.
#
#=head1 USE PP FEATURES EVEN THOUGH XS BACKEND
#
#Many methods are available with either JSON::XS or JSON::PP and
#when the backend module is JSON::XS, if any JSON::PP specific (i.e. JSON::XS unsupported)
#method is called, it will C<warn> and be noop.
#
#But If you C<use> C<JSON> passing the optional string C<-support_by_pp>,
#it makes a part of those unsupported methods available.
#This feature is achieved by using JSON::PP in C<de/encode>.
#
#   BEGIN { $ENV{PERL_JSON_BACKEND} = 2 } # with JSON::XS
#   use JSON -support_by_pp;
#   my $json = JSON->new;
#   $json->allow_nonref->escape_slash->encode("/");
#
#At this time, the returned object is a C<JSON::Backend::XS::Supportable>
#object (re-blessed XS object), and  by checking JSON::XS unsupported flags
#in de/encoding, can support some unsupported methods - C<loose>, C<allow_bignum>,
#C<allow_barekey>, C<allow_singlequote>, C<escape_slash> and C<indent_length>.
#
#When any unsupported methods are not enable, C<XS de/encode> will be
#used as is. The switch is achieved by changing the symbolic tables.
#
#C<-support_by_pp> is effective only when the backend module is JSON::XS
#and it makes the de/encoding speed down a bit.

#
#This routine will produce a <pm:Getopt::Long> specification from Rinci function
#metadata, as well as some more data structure in the result metadata to help
#producing a command-line help/usage message.
#
#Function arguments will be mapped to command-line options with the same name,
#with non-alphanumeric characters changed to `-` (`-` is preferred over `_`
#because it lets user avoid pressing Shift on popular keyboards). For example:
#`file_size` becomes `file-size`, `file_size.max` becomes `file-size-max`. If
#function argument option name clashes with command-line option or another
#existing option, it will be renamed to `NAME-arg` (or `NAME-arg2` and so on).
#For example: `help` will become `help-arg` (if `common_opts` contains `help`,
#that is).
#
#Each command-line alias (`cmdline_aliases` property) in the argument
#specification will also be added as command-line option, except if it clashes
#with an existing option, in which case this function will warn and skip adding
#the alias. For more information about `cmdline_aliases`, see `Rinci::function`.
#
#For arguments with type of `bool`, Getopt::Long will by default also
#automatically recognize `--noNAME` or `--no-NAME` in addition to `--name`. So
#this function will also check those names for clashes.
#
#For arguments with type array of simple scalar, `--NAME` can be specified more
#than once to append to the array.
#
#If `per_arg_json` setting is active, and argument's schema is not a "required
#simple scalar" (e.g. an array, or a nullable string), then `--NAME-json` will
#also be added to let users input undef (through `--NAME-json null`) or a
#non-scalar value (e.g. `--NAME-json '[1,2,3]'`). If this name conflicts with
#another existing option, a warning will be displayed and the option will not be
#added.
#
#If `per_arg_yaml` setting is active, and argument's schema is not a "required
#simple scalar" (e.g. an array, or a nullable string), then `--NAME-yaml` will
#also be added to let users input undef (through `--NAME-yaml '~'`) or a
#non-scalar value (e.g. `--NAME-yaml '[foo, bar]'`). If this name conflicts with
#another existing option, a warning will be displayed and the option will not be
#added. YAML can express a larger set of values, e.g. binary data, circular
#references, etc.
#
#Will produce a hash (Getopt::Long spec), with `func.specmeta`, `func.opts`,
#`func.common_opts`, `func.func_opts` that contain extra information
#(`func.specmeta` is a hash of getopt spec name and a hash of extra information
#while `func.*opts` lists all used option names).

#Try to produce a regexp object compatible with a certain perl version (should at
#least be >= 5.10).
#
#For example, in perl 5.14 regex stringification changes, e.g. `qr/hlagh/i` would
#previously be stringified as `(?i-xsm:hlagh)`, but now it's stringified as
#`(?^i:hlagh)`. If you set `plver` to 5.10 or 5.12, then this routine will
#still produce the former. It will also ignore regexp modifiers that are
#introduced in newer perls.
#
#Note that not all regexp objects are translatable to older perls, e.g. if they
#contain constructs not known to older perls like `(^...)` before perl 5.14.
