NAME ^

SHARYANTO::Array::Util - Array-related utilities

VERSION ^

This document describes version 0.76 of SHARYANTO::Array::Util (from Perl distribution SHARYANTO-Utils), released on 2014-10-11.

SYNOPSIS ^

 use SHARYANTO::Array::Util qw(match_array_or_regex split_array);

 match_array_or_regex('bar',  ['foo', 'bar', qr/[xyz]/]); # true, matches string
 match_array_or_regex('baz',  ['foo', 'bar', qr/[xyz]/]); # true, matches regex
 match_array_or_regex('oops', ['foo', 'bar', qr/[xyz]/]); # false

 my @res = split_array('--', [qw/--opt1 --opt2 -- foo bar -- --val/]);
 # -> ([qw/--opt1 --opt2/],  [qw/foo bar/],  [qw/--val/])

 my @res = split_array(qr/--/, [qw/--opt1 --opt2 -- foo bar -- --val/], 2);
 # -> ([qw/--opt1 --opt2/],  [qw/foo bar -- --val/])

 my @res = split_array(qr/(--)/, [qw/--opt1 --opt2 -- foo bar -- --val/], 2);
 # -> ([qw/--opt1 --opt2/],  [qw/--/],  [qw/foo bar -- --val/])

 my @res = split_array(qr/(-)(-)/, [qw/--opt1 --opt2 -- foo bar -- --val/], 2);
 # -> ([qw/--opt1 --opt2/],  [qw/- -/],  [qw/foo bar -- --val/])

DESCRIPTION ^

FUNCTIONS ^

split_array($str_or_re, \@array[, $limit]) => LIST

Like the split() builtin Perl function, but applies on an array instead of a scalar. It loosely follows the split() semantic, with some exceptions.

match_array_or_regex($needle, $haystack) -> any

Check whether an item matches (list of) values/regexes.

Examples:

 match_array_or_regex("abc", ["abc", "abd"]); # -> 1
 match_array_or_regex("abc", qr/ab./); # -> 1
 match_array_or_regex("abc", [qr/ab./, "abd"]); # -> 1
This routine can be used to match an item against a regex or a list of
strings/regexes, e.g. when matching against an ACL.

Since the smartmatch (~~) operator can already match against a list of strings or regexes, this function is currently basically equivalent to:

 if (reg($haystack) eq 'ARRAY') {
     return $needle ~~ @$haystack;
 } else {
     return $needle =~ /$haystack/;
 }

Arguments ('*' denotes required arguments):

Return value:

 (any)

match_regex_or_array($needle, $haystack) -> any

Alias for match_array_or_regex.

Examples:

 match_regex_or_array("abc", ["abc", "abd"]); # -> 1
 match_regex_or_array("abc", qr/ab./); # -> 1
 match_regex_or_array("abc", [qr/ab./, "abd"]); # -> 1
This routine can be used to match an item against a regex or a list of
strings/regexes, e.g. when matching against an ACL.

 }
