VERSION

This document describes version 0.016 of Sah::Schemas::Str (from Perl distribution Sah-Schemas-Str), released on 2023-10-23.

SAH SCHEMAS

The following schemas are included in this distribution:

  • hexstr

    String of bytes in hexadecimal notation, e.g. "ab99" or "CAFE".

    Whitespace is allowed and will be removed.

  • latin_alpha

    String containing only zero or more Latin letters, i.e. A-Z or a-z.

  • latin_alphanum

    String containing only zero or more Latin letters/digits, i.e. A-Za-z0-9.

  • latin_letter

    A single latin letter, i.e. A-Z or a-z.

  • latin_lowercase_alpha

    String containing only zero or more lowercases Latin letters, i.e. a-z.

    Uppercase letters will be coerced to lowercase.

  • latin_lowercase_letter

    A single latin lowercase letter, i.e. a-z.

  • latin_uppercase_alpha

    String containing only zero or more uppercase Latin letters, i.e. A-Z.

    Uppercase letters will be coerced to lowercase.

  • latin_uppercase_letter

    A single latin uppercase letter, i.e. A-Z.

  • lowercase_str

    String containing only zero or more lowercase letters.

    Uppercase letters will be coerced to lowercase.

  • non_empty_str

    A non-empty string (length >= 1) (alias for str1).

  • percent_str

    A number in percent form, e.g. "10.5%".

    This schema accepts floating number followed by percent sign. Unlike the percent schema from Sah::Schemas::Float, The percent sign will not be removed nor the number be converted to decimal (e.g. 50% to 0.5).

  • str1

    A non-empty string (length >= 1).

  • str_or_aos

    String or array (0+ length) of (defined) string.

  • str_or_aos1

    String or array (1+ length) of (defined) string.

  • str_or_code

    String or coderef (if string is of the form `sub {...}`).

    Either string or coderef is accepted.

    If string matches the regex qr/\Asub\s*\{.*\}\z/s, then it will be eval'ed into a coderef. If the code fails to compile, the value will be rejected. Note that this means you accept arbitrary code from the user to execute! Please make sure first and foremost that this is acceptable in your case.

    Currently string is eval'ed in the main package, without use strict or use warnings.

    This schema is handy if you want to accept string or coderef from the command-line.

  • str_or_re

    String or regex (if string is of the form `/.../`).

    Either string or Regexp object is accepted.

    If string is of the form of /.../ or qr(...), then it will be compiled into a Regexp object. If the regex pattern inside /.../ or qr(...) is invalid, value will be rejected.

    Currently, unlike in normal Perl, for the qr(...) form, only parentheses ( and ) are allowed as the delimiter.

    Currently modifiers i, m, and s after the second / are allowed.

  • str_or_re_or_code

    String, or regex (if string is of the form `/.../`), or coderef (if string is in the form of `sub { ... }`).

    Either string, Regexp object, or coderef is accepted.

    If string is of the form of /.../ or qr(...), then it will be compiled into a Regexp object. If the regex pattern inside /.../ or qr(...) is invalid, value will be rejected. Currently, unlike in normal Perl, for the qr(...) form, only parentheses ( and ) are allowed as the delimiter. Currently modifiers i, m, and s after the second / are allowed.

    If string matches the regex qr/\Asub\s*\{.*\}\z/s, then it will be eval'ed into a coderef. If the code fails to compile, the value will be rejected. Note that this means you accept arbitrary code from the user to execute! Please make sure first and foremost that this is acceptable in your case. Currently string is eval'ed in the main package, without use strict or use warnings.

    This schema is handy if you want to accept string or regex or coderef from the command-line.

  • uppercase_str

    String containing only zero or more uppercase letters.

    Uppercase letters will be coerced to lowercase.

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.
