=head1 NAME

Data::Sah::Coerce::perl::To_bool::From_str::common_words - Convert common true/false words (e.g. "yes","true","on","1" to "1", and "no","false","off","0" to "")

=head1 VERSION

This document describes version 0.050 of Data::Sah::Coerce::perl::To_bool::From_str::common_words (from Perl distribution Data-Sah-Coerce), released on 2021-10-18.

=head1 SYNOPSIS

To use in a Sah schema:

 ["bool",{"x.perl.coerce_rules"=>["From_str::common_words"]}]

=head1 DESCRIPTION

This coercion rule converts "true", "yes", "on" (matched case-insensitively) to
"1"; and "false", "no", "off", "0" (matched case-insensitively) to "". All other
strings are left untouched.

B<Note that this rule is incompatible with Perl's notion of true/false.> Perl
regards all non-empty string that isn't "0" (including "no", "false", "off") as
true. But this might be useful in CLI's or other places.

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required
beyond that are considered a bug and can be reported to me.
