Sah::Schemas::Perl - Sah schemas related to Perl
This document describes version 0.049 of Sah::Schemas::Perl (from Perl distribution Sah-Schemas-Perl), released on 2023-10-26.
The following schemas are included in this distribution:
perl::distname
Perl distribution name, e.g. Foo-Bar.
This is a schema you can use when you want to accept a Perl distribution name, e.g. WWW-Mechanize. It offers basic checking of syntax as well as a couple of conveniences. First, it offers completion from list of locally installed Perl distribution. Second, it contains coercion rule so you can also input Foo::Bar, Foo/Bar, Foo/Bar.pm, or even 'Foo.Bar' and it will be normalized into Foo-Bar.
WWW-Mechanize
Foo::Bar
Foo/Bar
Foo/Bar.pm
Foo-Bar
To see this schema in action on the CLI, you can try e.g. the dist-has-deb script from App::DistUtils and activate its tab completion (see its manpage for more details). Then on the CLI try typing:
dist-has-deb
% dist-has-deb WWW-<tab> % dist-has-deb dzp/<tab>
Note that this schema does not check that the Perl disribution exists on CPAN or is installed locally. To check that, use the perl::distname::installed schema. And there's also a perl::distname::not_installed schema.
perl::distname::installed
perl::distname::not_installed
perl::distname::default_this_dist
Perl distribution name, defaults to "this distribution".
See App::ThisDist's this_dist() for more details on how "this distribution" is determined. Note that App::ThisDist is not added as dependency automatically; you will have to add it manually.
this_dist()
App::ThisDist
Note: be careful when using this schema for actions that are destructive to a Perl dist or that change some things, because a user can perform those actions without giving an argument (e.g. a delete-dist script). It is safer to use this schema to perform a non=destructive action (e.g. ls-dist) and/or operate in dry-run mode by default.
delete-dist
ls-dist
perl::distname_with_optional_ver
Perl distribution name (e.g. Foo-Bar) with optional version number suffix (e.g. Foo-Bar@0.001).
For convenience (particularly in CLI with tab completion), you can input one of:
Foo::Bar Foo/Bar Foo/Bar.pm Foo.Bar
and it will be coerced into Foo-Bar form.
perl::distname_with_ver
Perl distribution name with version number suffix, e.g. Foo-Bar@0.001.
Foo::Bar@1.23 Foo/Bar@1.23 Foo/Bar.pm@1.23 Foo.Bar@1.23
perl::filename
Filename of Perl script/module/POD, e.g. /path/Foo/Bar.pm.
Use this schema if you want to accept a filesystem path containing Perl script, module, or POD. The value of this schema is in the convenience of CLI completion, as well as coercion from script or module name.
String containing filename of a Perl script or module or POD. For convenience, when value is in the form of:
Foo Foo.pm Foo.pod Foo::Bar Foo/Bar Foo/Bar.pm Foo/Bar.pod
and a matching .pod or .pm file is found in @INC, then it will be coerced (converted) into the path of that .pod/.pm file, e.g.:
@INC
/home/ujang/perl5/perlbrew/perls/perl-5.24.0/lib/site_perl/5.24.0/Foo/Bar.pm lib/Foo/Bar.pod
To prevent such coercion, you can use prefixing path, e.g.:
./Foo::Bar ../Foo/Bar /path/to/Foo/Bar
This schema comes with convenience completion too.
perl::funcname
Perl function name, either qualified with package name (e.g. Foo::subname) or unqualified (e.g. subname).
Currently function name is restricted to this regex:
\A[A-Za-z_][A-Za-z_0-9]*\z
Function name can be qualified (prefixed) by a package name, which is restricted to this regex:
[A-Za-z_][A-Za-z_0-9]*(::[A-Za-z_0-9]+)*
perl::identifier::qualified_ascii
Qualified identifier in Perl, without "use utf8" in effect.
perl::identifier::qualified_unicode
Unqualified identifier in Perl, with "use utf8" in effect.
perl::identifier::unqualified_ascii
Unqualified identifier in Perl, without "use utf8" in effect.
perl::identifier::unqualified_unicode
perl::modargs
Shorter alias for perl::modname_with_optional_args.
perl::modname
Perl module name, e.g. Foo::Bar.
This is a schema you can use when you want to accept a Perl module name. It offers basic checking of syntax as well as a couple of conveniences. First, it offers completion from list of locally installed Perl modules. Second, it contains coercion rule so you can also input Foo-Bar, Foo/Bar, Foo/Bar.pm or even 'Foo.Bar' and it will be normalized into Foo::Bar.
To see this schema in action on the CLI, you can try e.g. the pmless script from App::PMUtils and activate its tab completion (see its manpage for more details). Then on the CLI try typing:
pmless
% pmless M/<tab> % pmless dzp/<tab> % pmless Module/List/Wildcard % pmless Module::List::Wildcard
Note that this schema does not check that the Perl module exists or is installed locally. To check that, use the perl::modname::installed schema. And there's also a perl::modname::not_installed schema.
perl::modname::installed
perl::modname::not_installed
perl::modname::default_this_mod
Perl module, defaults to "this module".
See App::ThisDist's this_mod() for more details on how "this module" is determined. Note that App::ThisDist is not added as dependency automatically; you will have to add it manually.
this_mod()
Note: be careful when using this schema for actions that are destructive to a Perl module or that change some things, because a user can perform those actions without giving an argument (e.g. a delete-module script). It is safer to use this schema to perform a non=destructive action (e.g. man-module) and/or operate in dry-run mode by default.
delete-module
man-module
Name of a Perl module that is installed locally.
This schema is based on the perl::modname schema with an additional check that the perl module is installed locally. Checking is done using Module::Installed::Tiny. This check fetches the source code of the module from filesystem or %INC hooks, but does not actually load/execute the code.
Name of a Perl module that is not installed locally.
This schema is based on the perl::modname schema with an additional check that the perl module is not installed locally. Checking is done using Module::Installed::Tiny. This check fetches the source code of the module from filesystem or %INC hooks, but does not actually load/execute the code.
perl::modname_or_prefix
Perl module name (e.g. Foo::Bar) or prefix (e.g. Foo::Bar::).
Contains coercion rule so inputing Foo-Bar or Foo/Bar will be normalized to Foo::Bar while inputing Foo-Bar- or Foo/Bar/ will be normalized to Foo::Bar::
Foo-Bar-
Foo/Bar/
Foo::Bar::
See also: perl::modname and perl::modprefix.
perl::modprefix
perl::modname_pm
Perl module name in Foo/Bar.pm form.
This is just like the perl::modname schema except that instead of to Foo::Bar, it normalizes to Foo/Bar.pm.
perl::modname_with_optional_args
Perl module name (e.g. Foo::Bar) with optional arguments (e.g. Foo::Bar=arg1,arg2).
Perl module name with optional arguments which will be used as import arguments, just like the -MMODULE=ARGS shortcut that perl provides. Examples:
-MMODULE=ARGS
perl
Foo Foo::Bar Foo::Bar=arg1,arg2
See also: perl::modname. A two-element array from (coercible from JSON string) is also allowed:
["Foo::Bar", \@args]
perl::modname_with_optional_ver
Perl module name (e.g. Foo::Bar) with optional version number suffix (e.g. Foo::Bar@0.001).
perl::modname_with_ver
Perl module name with version number suffix, e.g. Foo::Bar@0.001.
perl::modnames
Array of Perl module names, e.g. ["Foo::Bar", "Baz"].
Array of Perl module names, where each element is of perl::modname schema, e.g. Foo, Foo::Bar.
Foo
Contains coercion rule that expands wildcard, so you can specify:
Module::P*
and it will be expanded to e.g.:
["Module::Patch", "Module::Path", "Module::Pluggable"]
The wildcard syntax supports jokers (?, *, **), brackets ([abc]), and braces ({one,two}). See Module::List::Wildcard for more details.
?
*
**
[abc]
{one,two}
Perl module prefix, e.g. Foo::Bar::.
Perl module prefix, e.g. Foo::Bar::. An empty prefix ('') is also allowed.
Contains coercion rule so you can also input:
Foo-Bar Foo-Bar- Foo-Bar Foo/Bar Foo/Bar/ Foo::Bar
and it will be normalized into Foo::Bar::.
perl::modprefixes
Perl module prefixes, e.g. ["", "Foo::", "Foo::Bar::"].
Array of Perl module prefixes, where each element is of perl::modprefix schema, e.g. Foo::, Foo::Bar::.
Foo::
Module::C*
["Module::CPANTS::", "Module::CPANfile::", "Module::CheckVersion::", "Module::CoreList::"]
The wildcard syntax supports jokers (?, '*) and brackets ([abc]). See the unix` type of wildcard in Regexp::Wildcards, which this coercion rule uses.
) and brackets (
). See the
perl::module::release::version
Expression to select module release.
perl::module::release::versions
perl::pm_filename
A .pm filename, e.g. /path/Foo.pm.
Use this schema if you want to accept a filesystem path containing Perl module. The value of this schema is in the convenience of CLI completion, as well as coercion from module name.
String containing filename of a Perl module. For convenience, when value is in the form of:
Foo Foo.pm Foo::Bar Foo/Bar Foo/Bar.pm
and a matching .pm file is found in @INC, then it will be coerced (converted) into the path of that .pm file, e.g.:
/home/ujang/perl5/perlbrew/perls/perl-5.24.0/lib/site_perl/5.24.0/Foo/Bar.pm
perl::pod_filename
A .pod filename, e.g. /path/Foo.pod.
Use this schema if you want to accept a filesystem path containing Perl POD. The value of this schema is in the convenience of CLI completion, as well as coercion from POD name.
String containing filename of a Perl .pod file. For convenience, when value is in the form of:
Foo Foo.pod Foo::Bar Foo/Bar Foo/Bar.pod
and a matching .pod file is found in @INC, then it will be coerced (converted) into the filesystem path of that .pod file, e.g.:
/home/ujang/perl5/perlbrew/perls/perl-5.24.0/lib/site_perl/5.24.0/Foo/Bar.pod
perl::pod_or_pm_filename
A .pod or .pm filename, e.g. /path/Foo.pm or /path/Bar/Baz.pod.
String containing filename of a Perl POD or module. For convenience, when value is in the form of:
Foo Foo.pod Foo.pm Foo::Bar Foo/Bar Foo/Bar.pod Foo/Bar.pm
This schema is like another schema perl::filename except that .pod is prioritized over .pm. If both Foo.pm and Foo.pod are found in @INC, the path to Foo.pod will be returned.
Foo.pm
Foo.pod
perl::podname
Perl POD name, e.g. Moose::Cookbook.
Perl POD name, e.g. Config, Some::Other::POD.
Config
Some::Other::POD
Basically the same as perl::modname, but with a different completion.
perl::qualified_funcname
Perl function name qualified with a package name, e.g. Foo::subname.
and package name is restricted to this regex:
This schema includes syntax validity check only; it does not check whether the function actually exists.
perl::release::version
One of known released versions of perl (e.g. 5.010 or 5.10.0).
Use this schema if you want to accept one of the known released versions of perl.
The list of releases of perl is retrieved from the installed core module Module::CoreList during runtime as well as the one used during build. One of both those Module::CoreList instances might not be the latest, so this list might not be up-to-date. To ensure that the list is complete, you will need to keep your copy of Module::CoreList up-to-date.
The list of version numbers include numified version (which, unfortunately, collapses trailing zeros, e.g. 5.010000 into 5.010) as well as the x.y.z version (e.g. 5.10.0).
perl::unqualified_funcname
Perl function name which must not be qualified with a package name, e.g. subname.
perl::version
Perl version object.
Use this schema if you want to accept a version object (see version). Coercion from string is provided.

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.
