NAME

String::Query::To::Regexp - Convert query to regular expression

VERSION

This document describes version 0.003 of String::Query::To::Regexp (from Perl distribution String-Query-To-Regexp), released on 2022-11-02.

SYNOPSIS

 use String::Query::To::Regexp qw(query2re);

 my $re;

 $re = query2re("foo");                       # => qr/\A(?=.*foo).*\z/s   -> string must contain 'foo'
 $re = query2re({ci=>1}, "foo";               # => qr/\A(?=.*foo).*\z/is  -> string must contain 'foo', case-insensitively
 $re = query2re("foo", "bar");                # => qr/\A(?=.*foo)(?=.*bar).*\z/s   -> string must contain 'foo' and 'bar', order does not matter
 $re = query2re("foo", "-bar");               # => qr/\A(?=.*foo)(?!.*bar).*\z/s   -> string must contain 'foo' but must not contain 'bar'
 $re = query2re({bool=>"or"}, "foo", "bar");  # => qr/\A(?:(?=.*foo)|(?!.*bar)).*\z/s  -> string must contain 'foo' or 'bar'
 $re = query2re({word=>1}, "foo", "bar");     # => qr/\A(?=.*\bfoo\b)(?!.*\bbar\b).*\z/s  -> string must contain words 'foo' and 'bar'; 'food' or 'lumbar' won't match

 $re = query2re({re=>1}, "foo", "/bar+/", qr/baz/i);  # => qr/(?^s:\A(?=.*foo\+)(?=.*(?^i:bar+))(?=.*(?^u:baz+)).*\z)/  -> allow regexes in queries

DESCRIPTION

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.
