Localization of software developed by ROSA is performed by means of Transifex. We use the public Transifex server and you can find our team here. If you are familiar with Transifex, you acn go directly to that page and skip the article below.

Transifex is a web-system that automates the process of translating different projects, allows organizing work of translators (or people who are interested in creating localization of software with excellent quality) and their cooperation with developers. Transifex allows to download, upload and edit translations, as well as display the general statistics of translated files/lines.

Offline vs. Online

With Transifex, you can perform all localization work online using embedded editors with Web UI. Alternatively, you can download necessary files to your machine, prepare localized strings and then upload your results back to the Transifex server.

How to edit translation offline?

A lot of programs exist to translate files on a local computer. Some of them are listed here. For example, you can use Qt Linguist.

Build-in Transifex editor is really convenient when you need to fix something quickly. But often lines for translations contain only one word or collocation, so you can't understand what it means out of context (a place in the application where this text appears). Moreover, a word in one language can have a large range of meanings in the others, can be translated as noun or verb, etc. So we strongly recommend not to translate text lines if you are not sure that your translation is correct or you don't know the context. In this case you can ask developers/owners of a project about location of the text line or start the application and find this location by yourself. In any case, untranslated text line is better than translated incorrectly.

Thus, translator can understand the context of applying of text line, Trasifex has comments. Because developers are interested in high quality translations, we strongly recommend that for developers to specify context and all nuances in comments. In practice, developers often forget about comments, so we strongly recommend to check translations at your computer. When using the offline mode, you can copy translations file to the application source code, compile the project and check translations at the working app. When using the online mode, it is recommended to download translations and test them in the same way.
