Tool to generate unique names.

UniqueNameGenerator is part of the universe framework.

Using the planet installer via light-cli

lt install Ling.UniqueNameGenerator

Using the uni command.

uni import Ling/UniqueNameGenerator

So far, the following use cases have been encountered:

• generate a unique filesystem name, to avoid file overwriting
• generate a unique item name, to avoid naming conflict

<?php

use Ling\UniqueNameGenerator\Generator\SimpleFileSystemUniqueNameGenerator;

require_once "bigbang.php";


$f = "/tmp/newFile.txt";

/**
* assuming /tmp/newFile.txt exists and /tmp/newFile-1.txt doesn't exist yet
*/
a(SimpleFileSystemUniqueNameGenerator::create()->generate($f));  // /tmp/newFile-1.txt    

<?php

use Ling\UniqueNameGenerator\Generator\ItemUniqueNameGenerator;

require_once "bigbang.php";


$f = "A";
a(ItemUniqueNameGenerator::create()->setNamePool([
    'A',
    'A-2',
    'A-3',
])->generate($f)); // A-4

Use this to generate names like this:

• fileName.jpg
• fileName - copy.jpg
• fileName - copy 2.jpg
• fileName - copy 3.jpg

or like this (default):

• fileName.jpg
• fileName-2.jpg
• fileName-3.jpg

Use the setGenerateAffixCb to generate the variable part, given an auto-incremented number. For instance to emulate the first of the above examples, we can do this:

<?php

use Ling\UniqueNameGenerator\Generator\SimpleFileSystemUniqueNameGenerator;

require_once "bigbang.php";


$f = "/tmp/newFile.txt";


a(SimpleFileSystemUniqueNameGenerator::create()->setGenerateAffixCb(function ($n) { // n is auto-incremented and starts with 1
    if ($n === 1) {
        return ' - copy';
    }
    return ' - copy ' . $n;
})->generate($f));
