How to get all i18n messages in Play 2 with Java - internationalization

Is there a way to retrieve all localized messages for a given locale in Play 2 Framework with Java? There seems to be API for Scala, but not for Java.
If there is no official API, what's the best way to do it?

Found nothing better then:
Properties prop = new Properties();
prop.load(play.Play.application().resourceAsStream("messages"));
return ok(Json.toJson(prop)).as("application/json");

Atually I'd ... separate them, I'd keep views/controller messages in common Play path but i18n file I prefer to keep in separate JS/JSON file.
Of course I don't know specification of your project but we have several hundreds of labels in project and only ~ 20 of them are for JS, so there's no reason to load something which won't be used ever.
On the other hand it's just lighter for Play to serve public static, then read it and converting to JSON each time.

UI5 - Load proper i18n_xy.properties at onInit and later on manually

We have the requirement, that we shall host an SAPUI5 application inside a java-application's host, which our vendor offered to us by implementing and exposing jxbrowser.
This vendor's java application offers an api, which can be accessed from within our SAPUI5 application.
This java api offers also an environment (or config-settings), where, amongst a rich set of settings, also a user language can be obtained.
And this language is neither a sap-logon language param nor is it guaranteed to be always the language which is set up in the "jx-browser" ( if possible at all, like in all real browsers ), and it uses the standard i18n _xy_AB acronym's naming style.
And I want to load the proper i18n_xy.properties at onInit of my first view and set them in the code.
We do have currently 4 of them ( _de,_it,_fr ), and the fallback is also present.
I am a little idiot, because I found some quick n dirty code, but this was about one month ago and I simply forgot the link and all of that. So now I need to ask( and maybe even for a best practice solution to this...)
So, additionally, another (my personal) requirement is, that, once I retrieve the right i18n file, I want to set it, in a way, that, whenever later on, I would use
info = this.getView().getModel("i18n").getResourceBundle().getText("obfuscated");
I always obtain the right text in the right language.
What I think of, is: Load the proper file ( according to the environment settings from the api ) in onInit, set this i18n as the proper one for the rest of the application's runtime and use a easy name for it, which will then be referred to as, maybe this:
info = this.getView().getModel("i18n_loaded").getResourceBundle().getText("obfuscated");
Is this possible, is this the right way, and , if not, which one is, according to some kind of guidelines, the best practice for this scenario ?
You can pass the parameter in the url:
sap-ui-language=en
Or set the default language in your JavaScript code:
sap.ui.getCore().getConfiguration().setLanguage("en-US");
I was not completely aware, that the determination of the used locale also works the other way around.
Meaning, if the ressource bundle contains e.g. 4 i18's,called i18_en, i18_it, i18_de, i18_fr, and the either the app is set up by
sap.ui.getCore().getConfiguration().setLanguage("en-US");
or the url-param, this not only means, that:
All ui-elements will be translated propery, once the locale's acronym is properly spotted
ALSO this is automatically replaced by the proper spotted ressource file and the translated text is retrieved properly....
info = this.getView().getModel("i18n").getResourceBundle().getText("obfuscated");
I was aware of how this fallback determination of a locale works, but I was not aware that it works also the other way around.
I close my question and i do not care about any rewards.

Is there a Go implementation of fs.ReadDir for Google Cloud Storage?

I am creating a web application in Go.
I have modified my working code so that it can read and write files on both a local filesystem and a bucket of Google Cloud Storage based on a flag.
Basically I included a small package in the middle, and I implemented my-own-pkg.readFile or my-own-pkg.WriteFile and so on...
I have replaced all calls in my code where I read or save files from the local filesystem with calls to my methods.
Finally these methods include a simple switch case that runs the standard code to read/write locally or the code to read/wrote from/to a gcp bucket.
My current problem
In some parts I need to perform a ReadDir to get the list of DirEntries and then cycle though them. I do not want to change my code except for replacing os.readDir with my-own-pkg.ReadDir.
So far I understand that there is not a native function in the gcp module. So I suppose (but here I need your help because I am just guessing) that I would need an implementation of fs.FS for the gcp. It being a new feature of go 1.6 I guess it's too early to find one.
So I am trying to create simply a my-own-pkg.ReadDir(folderpath) function that does the following:
case "local": { }
case "gcp": {
<Use gcp code sample to list objects in my bucket with Query.Prefix = folderpath and
Query.Delimiter="/"
Then create a slice of my-own-pkg.DirEntry (because fs.DkrEntry is just an interface and so it needs to be implemented... :-( ) and return them.
In order to do so I need to implement also the interface fs.DirEntry (which requires the implementation of interface for FileInfo and maybe something else...)
Question 1) is this the right path to follow to solve my issue or is there a better way?
Question 2) (only) if so, does the gcp method that lists object with a prefix and a delimiter return just files? I can't see a method that returns also the list of prefixes found
(If I have prefix/file1.txt and prefix/a/file2.txt I would like to get both "file1.txt" and "a" as files and prefixes...)
I hope I was enough clear... This time I can't include code because it's incomplete... But in case it helps I can paste what I can.
NOTE: by the way go 1.6 allowed me to solve elegantly a similar issue when dealing with assets either embedded or on the filesystem thanks to the existing implementation of fs.FS and the related ReadDirFS. So good if I could follow the same route 🙂
By the way I am going on studying and experimenting so in case I am successful I will contribute as well :-)
I think your abstraction layer is good but you need to know something on Cloud Storage: The directory doesn't exist.
In fact, all the object are put at the root of the bucket / and the fully qualified name of the object is /path/to/object.file. You can filter on a prefix, that return all the object (i.e. file because directory doesn't exist) with the same path prefix.
It's not a full answer to your question but I'm sure that you can think and redesign the rest of your code with this particularity in mind.

Ruby viewpoint with EWS

I am trying to get started using viewpoint against EWS within Ruby, and it's not making a lot of sense at the moment. I am wondering where I can get some good example code, or some pointers? I am using 1.0.0-beta.
For example: I know the name of the calendar folder I want to use, so I could search for it, but how to access methods in that folder once I find it? What are the appropriate parameters, etc...
Any advice?
If you haven't read it yet I would recommend the README file in the repository. It has a couple of examples that should put you on the right path. Also, the generated API documentation should give you enough to work with.
http://rubydoc.info/github/WinRb/Viewpoint/frames
At a very basic level you can get all of your calendar events with the following code:
calendar = client.get_folder :calendar
events = calendar.items
I hope that gives you a little more to get started with.
Follow-up:
Again, I would point you to the API docs for concrete methods like #items. There are however dynamically added methods depending on the type that you can fetch with obj.ews_methods. In the case of CalendarItem one of those methods is #name so you can call obj.name to get the folder name. The dynamic methods are all backed by a formatted Hash based on the returned SOAP packet. You can see it in its raw format by issuing obj.ews_item

Implementing resource list in WP7

I am porting a JAVA game to WP7. We have lots of images in our game and for loading them in JAVA use a function something like this "Resources.getImage(IMG_BULLETS);" where IMG_BULLETS is ID(an int) of the image.
But in WP7 we have to pass the path(a string) of image in order to load that.
Now my question is :
How to achieve a int-String mapping? so that I dont have to manually change the Id into path.
One possible solution comes in my mind is to have a .txt file having image path and its Id and parse that. But I am sure their is much better solution for this.
Note : we also have a multi-level folder structure for images and other files.
If you really want to refer to resources by int, you are going to have to map them some how to their path. As far as I know, there is no way to crawl your assets, and even if you could, i some how doubt you will get the same index order and you would have to redo your enum.
There are going to be a few hurdles you hit with trying to port and code changes. Another one, (one you will still have even with a txt file work around) will be that the contentManager.Load takes a type, eg, contentManager.Load<Texture2D>('path') returning a Texture2D.
One option would be to create your own singleton 'Resources' class that has get methods that take int to get the appropriate asset, however you will still need a mapping via xml or txt file of somekind. However this will require all your assets being loaded from the start which are more problems of their own (90mb memory limit and really long load time).
My advice would be look at the game development section of the App Hub and have a look at the game state example to help you see how you might be able to structure your game to work well with XNA.

CodeIgniter reusable message library

I'm using Message library (http://codeigniter.com/wiki/Message/) to display error messages on my site. This is the code that I'm using to display a message:
$this->message->set('error',$this->config->item('error.login'));
Right now I'm storing common messages in my config file (config/config.php) instead of writing the message every time. Is there a better way to do it? The config file is getting very long.
What I'm looking for is a better way to store re-usable text strings.
CodeIgniter's language class is what you're looking for:
CI Language Class
$this->message->set('error',$this->lang->line('error.login'));
A config file is more or less how you'd want to do it. It is simple, clear and light. But just because you are keeping it in a config file, that does not mean you need to keep it in config.php. The Config class allows you to have multiple config files, so have a special one for messages. Heck, you could even have several special ones for languages, and leave the one you are looking for in the config.php file!
$this->config->load( $this->config->get( "language_file_name" ) );
