# Cz::Sort(3pm)

Czech sort

## NAME

Cz::Sort - Czech sort

## SYNOPSIS

```
        use Cz::Sort;
        my $result = czcmp("_x j&á", "_&p");
        my @sorted = czsort qw(plachta plaňka Plánička plánička pláně);
        print "@sorted\n";
```

## DESCRIPTION

Implements czech sorting conventions, indepentent on current locales in effect, which are often bad. Does the four-pass sort. The idea and the base of the conversion table comes from Petr Olsak's program **csr** and the code is as compliant with CSN 97 6030 as possible.

The basic function provided by this module, is *czcmp*. If compares two scalars and returns the (-1, 0, 1) result. The function can be called directly, like

```
        my $result = czcmp("_x j&á", "_&p");
```

But for convenience and also because of compatibility with older versions, there is a function *czsort*. It works on list of strings and returns that list, hmm, sorted. The function is defined simply like

```
        sub czsort
                { sort { czcmp($a, $b); } @_; }
```

standard use of user's function in *sort*. Hashes would be simply sorted

```
        @sorted = sort { czcmp($hash{$a}, $hash{$b}) }
                                                keys %hash;
```

Both *czcmp* and *czsort* are exported into caller's namespace by default, as well as *cscmp* and *cssort* that are just aliases.

This module comes with encoding table prepared for ISO-8859-2 (Latin-2) encoding. If your data come in different one, you might want to check the module **Cstocs** which can be used for reencoding of the list's data prior to calling *czsort*, or reencode this module to fit your needs.
