TYPO3 Fluid Template get language code

Question

Is it possible to get the current language key (or code) in a TYPO3 Fluid template?

In the meantime I've found another solution using a view helper found here:

<?php
class Tx_AboUnitReservation_ViewHelpers_LanguageViewHelper extends Tx_Fluid_Core_ViewHelper_AbstractViewHelper {

    /**
     * Get the current language
     */
    protected function getLanguage() {
        if (TYPO3_MODE === 'FE') {
            if (isset($GLOBALS['TSFE']->config['config']['language'])) {
                return $GLOBALS['TSFE']->config['config']['language'];
            }
        } elseif (strlen($GLOBALS['BE_USER']->uc['lang']) > 0) {
            return $GLOBALS['BE_USER']->uc['lang'];
        }
        return 'en'; //default
    }

    /**
     * Return current language
     * @return  string
     */
    public function render() {
        return $this->getLanguage();
    }

}

?>

Which I use in the fluid template as follows.

<f:alias map="{isGerman: 'de'}">
    <f:if condition="{aboUnitReservation:language()} == {isGerman}">
        <script type="text/javascript" src="{f:uri.resource(path:'js/jquery.ui.datepicker-de-CH.js')}"></script>
    </f:if>
</f:alias>

Another solution using TypoScript object in Fluid template:

# German language
temp.language = TEXT
temp.language.value = at

# English language
[globalVar = GP:L = 1]
  temp.language.value = en
[global]

lib.language < temp.language

And Fluid code:

<f:if condition="{f:cObject(typoscriptObjectPath: 'lib.language')} == 'at'">
    <f:then>
        ...
    </f:then>
    <f:else>
        ...
    </f:else>
</f:if>

Object temp.language can contain any values, of course.
