Re: [keycloak-dev] i18n/l10n: English text in java code

The translation team will expect the key/value pairs to be in a po file. Developers push this to Zanata. The translation is done by the globalization team in Zanata. The translated po files are then incorporated into a build. The I18N QE team takes the build which has the translated po file and does 2 things. 1. They verify that the translated string appears as expected. 2. They verify that the translation is appropriate in the context in which it is presented.

Somehow a third-party bundle must be merged with our default bundle. Unless I completely misunderstand, the code I wrote will still work. New keys can be defined by using keys in client descriptions, client names, etc, etc.. These won't be in our message bundle, but would be in the bundle in a customers theme. This is why message bundles inherit from the parent theme. Custom providers and themes can further introduce new keys. #2 Rendering the whole bundle useless just because you're missing one key is just daft It is the correct thing to do. A missing key is like a null pointer. It deserves a RuntimeException. No it's not the correct thing to do. #3 There will quite likely be separate teams that do translations to those that do development, which means stack traces and log output is not the solution I don't see what that has to do with anything. You start with a set of bundles containing all the correct keys. Then you translate each bundle. If you accidentally delete a key then you want to know that right away. But we should indeed ask the translation team what they want to see. Sure, go ahead and ask them if they want to look for RuntimeExceptions in the server log. #4 Doing a check each time you pull a message bundle to compare with the base bundle is probably not that expensive, but still pretty daft thing to do You only load each bundle once. So the check only happens the first time you request the bundle. #5 A proper util that's used to translate bundles is much better - we can implement a page in the admin console that allows you to validate a bundle and print out all missing bundles. This is something that would be more developer friendly and also would be usable by non-developers (aka people with other language skills than Java) We should ask the translation team what they want to see and how they do their work. I'm sure that they don't expect a tool to be built into the product. None of our other products have that. I don't just care about our translation team, they will translate the built in keys, but they won't translate the ones introduced by users.

This is basically what happens with the code I wrote for the fix: https://github.com/keycloak/keycloak/pull/1690 You get an error in the console and then a stack trace on the server. The stack trace tells you exactly which key is missing. But the console doesn't crash or anything like that. You just switch back to your original language and everything works fine.

Manually having to go through all sorts of pages to look for missing keys is very error prone and time consuming, so will not be the best option for developers. In both cases above the correct way to do this would be to have a way to verify a message bundle. We need a tool that can quickly identify if there are missing keys and we could expose that through the admin console. We currently have a student looking at providing a UI for defining locales and she is also going to look at adding some way of identifying if a locale is missing keys and also to easily list only missing keys. For end users as I've said they will have no clue what ???key??? is, and even worse if we throw an exception/error just because a missing key we'll actually break the whole console just because of a missing key. It's a much better option to look for the key in another translation and display that. Chances are they will be able to interpret one or two English words. Certainly higher chance of that then them being able to interpret ???key???.

Let's just put this to rest and solve it once and for all. The simplest solution I can think of is to just compare keys when a new bundle is loaded. If any bundle has a missing key or it has key not found in the previous loaded bundle, we throw a RuntimeException. I can submit a patch for that in just a few minutes.

Having English suddenly pop-up in a German translation is just as obvious as a key. Besides as Stan points out you catch missing keys by comparing missing keys between English and German. However, if there is a mistake in a translation then a user may quite likely be able to interpret English text, while a user will not be able to interpret a key. So if a key is missing in a translation (which is obviously a "bug") it's better to display English than to display the key.

Alternative is to show key, but that's not going to help anyone A missing key is a bug and showing the message in the default locale may hide the problem. Even though showing the key does not help the end user it helps the developer and identifies the problem. For this reason I think showing the key would be a good idea. For our bundles, we could catch missing keys at build time. Failing that, I agree that displaying the key is better than falling back to English. This is especially true right now while we haven't completed the task of converting everything. If we fall back to English we won't know if the problem is a missing key or if the text just hasn't been converted yet. > * Should we change message bundles to UTF-8? Or is ISO 8859-1 going to work for all languages? Depends what those all languages are :-) I think UTF-8 is the best choice as it will handle practically any character. But if you're referring to Java resource bundles the encoding for .properties is ISO-8859-1 but there are means to handle any UTF-8 character. Yes, an UTF-8 character can be encoded in ISO-8859-1. Java provides a native2ascii tool for converting entire files. The resource bundle tools in most IDE's do this for you automatically. So you just edit as UTF-8 and it saves the bundle as ISO-8859-1. We can read our bundles as UTF-8 if we want to do that. I'd rather not, because I'm not sure what we might run into down the road with Java assuming resource bundles are always ISO-8859-1. But I'd like to get the perspective of people who have handled resource bundles in languages that are not fully supported by ISO-8859-1. Is it too much of a pain to do a conversion or do the tools make the process seamless?
