Multilingual

Plugin para adicionar o DeCS - Descritores em Ciências da Saúde ao drupal 7.

This sandbox project provides a translatable Boxes-Plugin (for Drupal 6), that uses i18nstrings.

Disable the locale_translate_edit_form_validate validation.

This tiny module allow users to translate their blocks using i18n and Wysiwyg as seen in this post.

The Simple I18n module implements a trivial patter matching markup to enclose your localizable strings. Anything that is sent to the user using a theme page template (and is not published in the /admin section) gets parsed by this module, so when the markup is found it is automatically filtered and otputted in the current language.

Uses

For localizing menu links, terms, views, field labels, ...

Use the simple in-line markup:

This small glue module adds two fields to the entity translation form that allows to translate the menu title and description associated with the node.

This module creates a Language Field in D7 and D8. It provides a Field Formatter with several options. Flag icons can be used using either the Language Icons module or the Flags module

Use this module if you need more languages then the enabled languages, but do not need the translations. Example: Your site contains two configured languages, but contains content type 'Manuals' in 5 languages.

This module provides lightweight GeoIP services using the free GeoIP service freegeoip.net that allows theme display changes based on a visitor's country, as inferred from their IP.

A tentative roadmap includes integration with the GeoIP API module (once that module is migrated to D7 and provided it can be extended to support alternate engines), integration with contexts (in-module at first, then through the GeoIP API context module integration), and additional administration options.

Add possibility to assign a specific language to a domain or domain alias (if domain_alias module is installed)

RTL means Right to Left, it's a term used to describe the status of the interface when viewing it in a language like Arabic (right to left written langauge). The current status of RTL in Drupal core is to flip some CSS rules in your style files. The aim of this project is to make this fully automated. You create a theme or a module? no need to worry about RTL support, we will do that for you!
