After a long break, I’m back working on KFM. I’ve done an average of maybe 2 hours every day this week, cleaning up code and preparing for future plans.
What I’m working on at the moment is a rewrite of the translations code. There are a few things wrong with the way that it works at the moment:
en.js for example.
- Whenever KFM is loaded, the entire JS language file is loaded, even if very little of it will actually be used.
- There is no easy way apart from hacking KFM to add translations for user-contributed plugins.
The solution we (Benjamin and myself) have come up with is to use a database solution, with an import facility for plugins. The idea is a complete rewrite of how we do it.
Currently, translations are recorded in a JS object something like this:
Errors : "ÃÅ¾Ã‘Ë†ÃÂ¸ÃÂ±ÃÂºÃÂ¸",
LastModified : "ÃÂ¿ÃÂ¾Ã‘ÂÃÂ»ÃÂµÃÂ´ÃÂ½ÃÂ¸ÃÂ¹ Ã‘â‚¬ÃÂ°ÃÂ· ÃÂ¸ÃÂ·ÃÂ¼ÃÂµÃÂ½ÃÂµÃÂ½"
The above is easy to use in KFM, in that the strings can be accessed using normal object notation,
kfm.lang.Errors for example. However, it should be easier.
What we will be doing is to convert all language files so they are written using the English string as the key instead of a code such as “
LastModified“. And, using the common nomenclature of other languages, the translation will be done such as:
alert(__("What do you want to rename %1 to?","default",filename));, where the second parameter is the language context (are we talking about files, people, dogs, etc?).
To help improve the speed at which KFM opens, only the most popular strings will be preloaded. If an unknown string is requested, it will be loaded through AJAX.
How that will work is that all translations will be asynchronous. When you request a translation, a
span element will be returned containing the translation. If the translation is already known or cached by the client, then the element will be pre-filled. Otherwise, an AJAX request will be fired off, and when it returns, the element will be populated.
The popularity of the strings will be determined by the number of requests for it.
On the server side, when a request comes in, KFM will search its database looking for the string. If it is found, it is returned (and its ‘requests’ field incremented). If it is not found, then all installed plugins will be searched for language files, which will be imported into the database then returned. If the string is not found anywhere, then the plain English is recorded in the database, and a note is added that the translation was not found.
I’m considering whether or not to add in a bit which periodically reports back to the main KFM server a list of missing translations. Also, a periodic report of popular strings and even of unused strings, allowing us to prune the files for future releases.
If you want to try out the work, then download a copy of the trunk via SVN:
