Grav LangSwitcher Plugin

LangSwitcher

LangSwitcher is a Grav plugin that provides native language text links to switch between Multiple Languages in Grav 0.9.30 or greater.

Installation

Installing the LangSwitcher plugin can be done in one of two ways. Our GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.

GPM Installation (Preferred)

The simplest way to install this plugin is via the Grav Package Manager (GPM) through your system's Terminal (also called the command line). From the root of your Grav install type:

bin/gpm install langswitcher

This will install the LangSwitcher plugin into your /user/plugins directory within Grav. Its files can be found under /your/site/grav/user/plugins/langswitcher.

Manual Installation

To install this plugin, just download the zip version of this repository and unzip it under /your/site/grav/user/plugins. Then, rename the folder to langswitcher. You can find these files either on GitHub or via GetGrav.org.

You should now have all the plugin files under

/your/site/grav/user/plugins/langswitcher

Usage

The langswitcher plugin doesn't require any configuration. You do however need to add the included Twig partials template into your own theme somewhere you want the available languages to be displayed.

{% include 'partials/langswitcher.html.twig' %}

Something you might want to do is to override the look and feel of the langswitcher, and with Grav it is super easy.

Copy the template file langswitcher.html.twig into the templates folder of your custom theme:

/your/site/grav/user/themes/custom-theme/templates/partials/langswitcher.html.twig

You can now edit the override and tweak it however you prefer.

Usage of the hreflang partial

A second template is available for hreflang annotations in the header of the page. In order to emit language annotations for the available languages of a page you need to add the corrsponding Twig partial template into the <head> section of your page, which can typically be found in base.html.twig:

{% include 'partials/langswitcher.hreflang.html.twig' %}

This will generate something like:

<link rel="alternate" href="http://example.com/en" hreflang="en" />
<link rel="alternate" href="http://example.com/de" hreflang="de" />
<link rel="alternate" href="http://example.com/zh-cn" hreflang="zh-cn" />

Updating

As development for the LangSwitcher plugin continues, new versions may become available that add additional features and functionality, improve compatibility with newer Grav releases, and generally provide a better user experience. Updating LangSwitcher is easy, and can be done through Grav's GPM system, as well as manually.

GPM Update (Preferred)

The simplest way to update this plugin is via the Grav Package Manager (GPM). You can do this with this by navigating to the root directory of your Grav install using your system's Terminal (also called command line) and typing the following:

bin/gpm update langswitcher

This command will check your Grav install to see if your LangSwitcher plugin is due for an update. If a newer release is found, you will be asked whether or not you wish to update. To continue, type y and hit enter. The plugin will automatically update and clear Grav's cache.

Note: Any changes you have made to any of the files listed under this directory will also be removed and replaced by the new set. Any files located elsewhere (for example a YAML settings file placed in user/config/plugins) will remain intact.

Configuration

Simply copy the user/plugins/langswitcher/langswitcher.yaml into user/config/plugins/langswitcher.yaml and make your modifications.

enabled: true
built_in_css: true

Options are pretty self explanatory.

Redirecting after switching language

To have Grav redirect to the default page route after switching language, you must add the following configuration to user/config/system.yaml

pages:
  redirect_default_route: true
