vria / nodiacritic

Twig filter to strip all diacritical signs from strings

nodiacritic

Tiny helper function that removes all diacritical signs from characters. Function is aware of German and Danish diacritic particularities.

Installation

composer.json

"require": {
    "vria/nodiacritic": "0.*"
}

Use

use VRia\Utils\NoDiacritic;

$noDiacriticString = NoDiacritic::filter("Révolution française");

As expected, the result is Revolution francaise.

The library is aware of particularities in German and Danish language:

use VRia\Utils\NoDiacritic;

$noAccentsNiceStreet = NoDiacritic::filter("Schöne straße", "de");

The result is Schoene strasse.

The code is inspired by WordPress' remove_accents function.

nodiacritic's Issues

Request to relicense to "GPL 2.0 or later"

This library is used in a WordPress plugin: https://github.com/publishpress/PublishPress-Planner/blob/a4a52f92eb6c972a3b7c590ebbcfb4a0cb6b1c96/composer.lock#L10096

The WordPress plugin is licensed as GPLv2 or later: https://github.com/publishpress/PublishPress-Planner#license

However, this has no effect because the usage of this library would require everything to be licensed as GPLv2 or compatible. It's not possible to use a GPLv2 component in a GPLv3 context, whereas GPLv2-or-later is allowed.

This means that when another plugin is licensed as GPLv3, then using PublishPress Planner is no longer allowed because of the license clash.

Here are the corresponding issues:
publishpress/PublishPress-Planner#1237
lucatume/wp-browser#600

As short-term solution (until there is a better one), it would be easiest, if this library was relicensed to "GPL 2.0 or later" instead of "GPL 2.0 only" (see https://github.com/vria/nodiacritic/blob/0eb3cafbca8ac1b478bd4dabe0666d8b0d3cba6c/LICENSE and

nodiacritic/composer.json

Line 7 in 0eb3caf

"license": "GPL-2.0",

)

Readme improvement

The readme file can be improve by adding the namespace of the class, in the ##Usage section.

use VRia\Utils\NoDiacritic;

$noDiacriticString = NoDiacritic::filter("Révolution française");
