NAME

Sah::Schemas::Code - Various schemas related to 'code' type and coderefs

VERSION

This document describes version 0.003 of Sah::Schemas::Code (from Perl distribution Sah-Schemas-Code), released on 2023-12-20.

SAH SCHEMAS

The following schemas are included in this distribution:

  • code_from_str

    Coderef from eval\`ed string.

    This schema accepts coderef or string which will be eval'ed to coderef. Note that this means allowing your user to provide arbitrary Perl code for you to execute! Make sure first and foremost that security-wise this is acceptable in your case.

    By default eval() is performed in the main namespace and without stricture or warnings. See the parameterized version Sah::PSchema::code_from_str if you want to customize the eval().

    What's the difference between this schema and str_or_code (from Sah::Schemas::Str)? Both this schema and str_or_code accept string, but this schema will directly compile any input string while str_or_code will only convert string to code if it is in the form of sub { ... }. In other words, this schema will always produce coderef, while str_or_code can produce strings also.

CONTRIBUTING

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.
