In the article below you will learn:

1. How often translations are ported from Transifex to CKEditor;
2. Why gettext .po files are used in the CKEditor localization project;
3. How to manually test new translations.

When Will My Translation Be Published?

Below is a simple diagram that shows when the language strings added in Transifex will land in a new CKEditor release.

Once generated, the development snapshot is immediately published on the CKEditor Nightly Website. The whole process takes up to 24 hours, so after updating the translation, the next day you can download a development snapshot that will contain updated files. You can then test if everything works as expected.

Please note that the development shapshot is exactly what the name implies. For a production environment it is more advisable to wait for the next stable release with updated language files.

Why Are .po Files Used in Tansifex?

CKEditor is a browser-based WYSIWYG editor written in JavaScript. The language files used by CKEditor are also JavaScript files. This is the best option performance-wise.

For many translators working with JavaScript source code was not comfortable. Storing text in plain JavaScript files meant that the translator had to know how to code in JavaScript — strings had to be escaped properly, multiline strings had to be written in a special way etc. JavaScript language files are in fact small programs, for example the language file for the a11yhelp plugin calls a function:

CKEDITOR.plugins.setLang( 'a11yhelp', 'he', {
	accessibilityHelp : {
	...
	}
}

All the issues mentioned above as well as the very specific format of the language files used by CKEditor core and plugins lead to the conclusion that a simplified intermediate format (gettext) is needed to make the localization process more straightforward and the integration with Transifex easier.

What Does it Mean to Me?

In the CKEditor localization project at Transifex you only have access to the gettext (.po) files. It means that for example if you download a resource for offline translation, you will get a .po file, not a JavaScript file. You can load this file into your favorite .po file editor like Gtranslator, Lokalize, or Poedit for offline translation, but you cannot use it directly with CKEditor.

How Can I Immediately Test New Translations?

At some stage you may want to immediately check if your translation fits into the place where it is used. As explained above, the propagation of changes between Transifex and the CKEditor nightly build takes up to 24 hours. If you have doubts regarding the string context, make sure to always check the Details tab of a language string and read the Comment ⁽¹⁾ to understand where the string is used.

If you are still unsure, you can also check the String ID ⁽²⁾ in the Details tab. The String ID is nothing else than the name of a variable that is used inside the JavaScript language files. For example, the common.browseServer ID is equal to the following object:

common :
{
	browseServer : '...'
}

After finding the right entry in the appropriate CKEditor language file (if you are translating the core, the language file is located in the lang folder), you may modify the string you are interested in. Save the file and launch CKEditor to see whether your translation fits the context and available space.
