Extractor

emsco_asset_meta

This filter returns you a ExtractedData object from an asset's hash:

twig

{% set meta = source.file.sha1|emsco_asset_meta %}
{{ meta.locale }}

You can also specify a filename and bypass the 3MB protection:

twig

{% set meta = source.file.sha1|emsco_asset_meta('raport.pdf', true) %}
{{ meta.locale }}

This filter returns you a text's locale guessed by Tika:

twig

{{ 'Hello comment allez-vous?'|emsco_guess_locale }}
{# Displays a 'fr' #}
