Sah::Schema::country::code::alpha3 - Country code (alpha-3)
This document describes version 0.009 of Sah::Schema::country::code::alpha3 (from Perl distribution Sah-Schemas-Country), released on 2023-08-07.
"" # INVALID "ID" # INVALID (Only alpha-3 codes are allowed) "IDN" # valid, becomes "idn" "xx" # INVALID "xxx" # INVALID
To check data against this schema (requires Data::Sah):
use Data::Sah qw(gen_validator); my $validator = gen_validator("country::code::alpha3*"); say $validator->($data) ? "valid" : "INVALID!";
The above validator returns a boolean result (true if data is valid, false if otherwise). To return an error message string instead (empty string if data is valid, a non-empty error message otherwise):
my $validator = gen_validator("country::code::alpha3", {return_type=>'str_errmsg'}); my $errmsg = $validator->($data); # a sample valid data $data = "IDN"; my $errmsg = $validator->($data); # => "" # a sample invalid data $data = ""; my $errmsg = $validator->($data); # => "Must be one of [\"phl\",\"esp\",\"tkm\",\"ago\",\"jor\",\"cyp\",\"cuw\",\"blm\",\"can\",\"aia\",\"hun\",\"atg\",\"vat\",\"esh\",\"glp\",\"mli\",\"mda\",\"ind\",\"eth\",\"png\",\"asm\",\"bfa\",\"guy\",\"deu\",\"ukr\",\"jpn\",\"prt\",\"cck\",\"lao\",\"tkl\",\"blr\",\"afg\",\"are\",\"gab\",\"swz\",\"vnm\",\"idn\",\"tcd\",\"bgd\",\"srb\",\"ala\",\"mwi\",\"rus\",\"bes\",\"tgo\",\"che\",\"zwe\",\"cok\",\"mne\",\"mar\",\"guf\",\"grl\",\"sjm\",\"mmr\",\"flk\",\"plw\",\"ben\",\"bmu\",\"gnq\",\"bol\",\"lca\",\"sgs\",\"zaf\",\"omn\",\"shn\",\"gtm\",\"nam\",\"lso\",\"iot\",\"svn\",\"gnb\",\"fro\",\"cmr\",\"bra\",\"grc\",\"bel\",\"niu\",\"gmb\",\"eri\",\"pyf\",\"arg\",\"abw\",\"nld\",\"hmd\",\"vgb\",\"dza\",\"hti\",\"hnd\",\"mac\",\"msr\",\"mtq\",\"tto\",\"tca\",\"chn\",\"mhl\",\"egy\",\"sxm\",\"pse\",\"qat\",\"fsm\",\"lby\",\"tza\",\"chl\",\"ita\",\"mrt\",\"moz\",\"mng\",\"cod\",\"pan\",\"khm\",\"smr\",\"arm\",\"cxr\",\"aut\",\"prk\",\"uga\",\"gum\",\"kgz\",\"ncl\",\"kaz\",\"bvt\",\"gbr\",\"lie\",\"nga\",\"ton\",\"ner\",\"mco\",\"ggy\",\"sgp\",\"bgr\",\"rwa\",\"brn\",\"isr\",\"civ\",\"ltu\",\"imn\",\"slv\",\"bih\",\"fji\",\"vut\",\"svk\",\"cri\",\"blz\",\"gin\",\"nzl\",\"wlf\",\"cze\",\"dom\",\"umi\",\"npl\",\"nor\",\"sur\",\"pol\",\"gib\",\"yem\",\"isl\",\"syr\",\"jey\",\"kna\",\"tjk\",\"fin\",\"reu\",\"bhs\",\"brb\",\"cym\",\"cub\",\"maf\",\"pcn\",\"grd\",\"atf\",\"hrv\",\"gha\",\"uzb\",\"rou\",\"nic\",\"aus\",\"zmb\",\"caf\",\"kir\",\"slb\",\"tls\",\"sau\",\"and\",\"per\",\"pak\",\"ecu\",\"geo\",\"ven\",\"tur\",\"bdi\",\"mdv\",\"sen\",\"mdg\",\"lbr\",\"mnp\",\"kor\",\"irl\",\"fra\",\"dma\",\"sle\",\"dnk\",\"irn\",\"jam\",\"wsm\",\"stp\",\"aze\",\"dji\",\"som\",\"pry\",\"mys\",\"cpv\",\"ata\",\"tha\",\"vct\",\"kwt\",\"mex\",\"alb\",\"usa\",\"ury\",\"nru\",\"sdn\",\"spm\",\"pri\",\"mus\",\"lva\",\"bhr\",\"swe\",\"lux\",\"tun\",\"twn\",\"col\",\"lka\",\"mlt\",\"lbn\",\"myt\",\"cog\",\"mkd\",\"com\",\"nfk\",\"est\",\"ssd\",\"ken\",\"tuv\",\"syc\",\"bwa\",\"hkg\",\"vir\",\"irq\",\"btn\"]"
Often a schema has coercion rule or default value rules, so after validation the validated value will be different from the original. To return the validated (set-as-default, coerced, prefiltered) value:
my $validator = gen_validator("country::code::alpha3", {return_type=>'str_errmsg+val'}); my $res = $validator->($data); # [$errmsg, $validated_val] # a sample valid data $data = "IDN"; my $res = $validator->($data); # => ["","idn"] # a sample invalid data $data = ""; my $res = $validator->($data); # => ["Must be one of [\"phl\",\"esp\",\"tkm\",\"ago\",\"jor\",\"cyp\",\"cuw\",\"blm\",\"can\",\"aia\",\"hun\",\"atg\",\"vat\",\"esh\",\"glp\",\"mli\",\"mda\",\"ind\",\"eth\",\"png\",\"asm\",\"bfa\",\"guy\",\"deu\",\"ukr\",\"jpn\",\"prt\",\"cck\",\"lao\",\"tkl\",\"blr\",\"afg\",\"are\",\"gab\",\"swz\",\"vnm\",\"idn\",\"tcd\",\"bgd\",\"srb\",\"ala\",\"mwi\",\"rus\",\"bes\",\"tgo\",\"che\",\"zwe\",\"cok\",\"mne\",\"mar\",\"guf\",\"grl\",\"sjm\",\"mmr\",\"flk\",\"plw\",\"ben\",\"bmu\",\"gnq\",\"bol\",\"lca\",\"sgs\",\"zaf\",\"omn\",\"shn\",\"gtm\",\"nam\",\"lso\",\"iot\",\"svn\",\"gnb\",\"fro\",\"cmr\",\"bra\",\"grc\",\"bel\",\"niu\",\"gmb\",\"eri\",\"pyf\",\"arg\",\"abw\",\"nld\",\"hmd\",\"vgb\",\"dza\",\"hti\",\"hnd\",\"mac\",\"msr\",\"mtq\",\"tto\",\"tca\",\"chn\",\"mhl\",\"egy\",\"sxm\",\"pse\",\"qat\",\"fsm\",\"lby\",\"tza\",\"chl\",\"ita\",\"mrt\",\"moz\",\"mng\",\"cod\",\"pan\",\"khm\",\"smr\",\"arm\",\"cxr\",\"aut\",\"prk\",\"uga\",\"gum\",\"kgz\",\"ncl\",\"kaz\",\"bvt\",\"gbr\",\"lie\",\"nga\",\"ton\",\"ner\",\"mco\",\"ggy\",\"sgp\",\"bgr\",\"rwa\",\"brn\",\"isr\",\"civ\",\"ltu\",\"imn\",\"slv\",\"bih\",\"fji\",\"vut\",\"svk\",\"cri\",\"blz\",\"gin\",\"nzl\",\"wlf\",\"cze\",\"dom\",\"umi\",\"npl\",\"nor\",\"sur\",\"pol\",\"gib\",\"yem\",\"isl\",\"syr\",\"jey\",\"kna\",\"tjk\",\"fin\",\"reu\",\"bhs\",\"brb\",\"cym\",\"cub\",\"maf\",\"pcn\",\"grd\",\"atf\",\"hrv\",\"gha\",\"uzb\",\"rou\",\"nic\",\"aus\",\"zmb\",\"caf\",\"kir\",\"slb\",\"tls\",\"sau\",\"and\",\"per\",\"pak\",\"ecu\",\"geo\",\"ven\",\"tur\",\"bdi\",\"mdv\",\"sen\",\"mdg\",\"lbr\",\"mnp\",\"kor\",\"irl\",\"fra\",\"dma\",\"sle\",\"dnk\",\"irn\",\"jam\",\"wsm\",\"stp\",\"aze\",\"dji\",\"som\",\"pry\",\"mys\",\"cpv\",\"ata\",\"tha\",\"vct\",\"kwt\",\"mex\",\"alb\",\"usa\",\"ury\",\"nru\",\"sdn\",\"spm\",\"pri\",\"mus\",\"lva\",\"bhr\",\"swe\",\"lux\",\"tun\",\"twn\",\"col\",\"lka\",\"mlt\",\"lbn\",\"myt\",\"cog\",\"mkd\",\"com\",\"nfk\",\"est\",\"ssd\",\"ken\",\"tuv\",\"syc\",\"bwa\",\"hkg\",\"vir\",\"irq\",\"btn\"]",""]
Data::Sah can also create validator that returns a hash of detailed error message. Data::Sah can even create validator that targets other language, like JavaScript, from the same schema. Other things Data::Sah can do: show source code for validator, generate a validator code with debug comments and/or log statements, generate human text from schema. See its documentation for more details.
To validate function parameters against this schema (requires Params::Sah):
use Params::Sah qw(gen_validator); sub myfunc { my @args = @_; state $validator = gen_validator("country::code::alpha3*"); $validator->(\@args); ... }
To specify schema in Rinci function metadata and use the metadata with Perinci::CmdLine (Perinci::CmdLine::Lite) to create a CLI:
# in lib/MyApp.pm package MyApp; our %SPEC; $SPEC{myfunc} = { v => 1.1, summary => 'Routine to do blah ...', args => { arg1 => { summary => 'The blah blah argument', schema => ['country::code::alpha3*'], }, ... }, }; sub myfunc { my %args = @_; ... } 1; # in myapp.pl package main; use Perinci::CmdLine::Any; Perinci::CmdLine::Any->new(url=>'/MyApp/myfunc')->run; # in command-line % ./myapp.pl --help myapp - Routine to do blah ... ... % ./myapp.pl --version % ./myapp.pl --arg1 ...
To validate some data on the CLI, you can use validate-with-sah utility. Specify the schema as the first argument (encoded in Perl syntax) and the data to validate as the second argument (encoded in Perl syntax):
% validate-with-sah '"country::code::alpha3*"' '"data..."'
validate-with-sah has several options for, e.g. validating multiple data, showing the generated validator code (Perl/JavaScript/etc), or loading schema/data from file. See its manpage for more details.
validate-with-sah
To create a type constraint and type library from a schema (requires Type::Tiny as well as Type::FromSah):
package My::Types { use Type::Library -base; use Type::FromSah qw( sah2type ); __PACKAGE__->add_type( sah2type('country::code::alpha3*', name=>'CountryCodeAlpha3') ); } use My::Types qw(CountryCodeAlpha3); CountryCodeAlpha3->assert_valid($data);
Accept only current (not retired) codes. Only alpha-3 codes are accepted.
Code will be converted to lowercase.

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
