[OpenLayers-Dev] Additional Lang Files

[Chris Claydon]

Thank you very much for this information. (I was looking at the 2.7 source rather than trunk - the Spanish file must have been added after that branch was created).

Following your recommendation, we'll implement the new resource(s) based on the de.js file (i.e. two-character extension, extend English resources).

Chris.

Chris,

I think what you're seeing is clear evidence that there is not a strong
consensus on the right way to do language files yet. :) Our typical
coding style dictator (Erik) was not involved in the i18n process, so we
didn't get the usual set of process instructions for these files :)

What I would recommend is:
 * Creating a two-char lang file for the 'base' of the language

 * If there is a different interpretation of the language for a
   sub-language -- for example, en-GB spells 'colour' differently --
   extend from the default/'base' of that language.

   OpenLayers will automatically handle taking the user's client
   language ("en-GB") and falling back to en if there is no -GB
   translation file.

 * I don't have an opinion on whether we should extend from English
   or not. If we do, then missing translations get an english string. I
   we don't, missing translations get a string like
   'olMessageStringKey'. I tend to think the former is better than the
   latter -- at least *some* foreign speakers will be able to handle it,
   as opposed to 'none'.

Not yet, but I'm glad to hear you're interested in helping to build them
:) More seriously, I'd welcome a cleanup according to the suggestions
above, barring any clear objections on a technical basis from other
members of the community.

Also, I'm presuming you're aware that there is already a spanish
translation...
