I didn't find any information about that topic. Is there any way to define an array in the standard play config file app.config which have such the values as?
application.secret="Gk<9kCgMu#A62eyfcJ;YZ2nFnA;4324/gfdg]afdsfds"
application.langs="en"
application.global=common.Global
Yes, it is possible and described in the Play configuration chapter.
In general, what you are looking for is this:
my.setting="[value1,value2,value3]"
In your code you can access it like this:
Play.current.configuration.getStringList("my.setting") //returns an Option[java.util.List[String]]
You may also use getLongList, getBooleanList and so on.
I find this answer searching for "play framework config array".
For Play 2.7 the correct syntax for a List is:
my.setting=["value1","value2","value3"]
otherwise you get an Exception like
com.typesafe.config.ConfigException$WrongType: application.conf # file:/xxxxx/application.conf: 12: my.setting has type STRING rather than LIST
Hope this helps someone else.

I wanted writing an IDE plugin to simplify work with references to code in my documentation, but decided to first check the existence of a specification (like URI) so as not to reinvent the wheel.
I tried to find the answer to this on the internet but failed.
We know that such references work in different IDEs:
appRoot.folder.file.Class#method
appRoot.folder.file:35
appRoot/fodler/file.ext:35
But what if you need to get the path to the nested property JSON or XML?
I naively imagine that the sign # means the root and then for the JSON path I could use something like this:
appRoot/folder/jsonFile.json#oneLevelProp.twoLevelProp
But this of course does not work at the current moment in any IDE that I know of.
I have gateway.properties file and it has following content:
current.path=c:/projects/sdk/
log.path=storage/logs
Here, in this file:
Either, I want to add third variable which is current.log.path and its value must be:
current.log.path=current.path + log.path
Or, I want to append string to current.path variable as below:
current.path=current.path+log.path
I have a situation that I can't do this concatenation/append job in my Java file. In Java its pretty simple but I have no idea how to do within file itself.
There is no built-in mechanism to have something like variables in a property file. You could try Apache Commons Configuration. I think it is what you are looking for.
After looking around for a while I was able to understand how the json: tags are used in the Go language. However two tags I have come across I'm still lost on, and can't seem to find documentation on it.
Both pertain to a REST api service and the full code can be found here-> code.google.com
What is the root: tag used for
gorest.RestService `root:"/orders-service/" consumes:"application/json" produces:"application/json"`
as well how does the method: tag work?
userDetails gorest.EndPoint `method:"GET" path:"/users/{Id:int}" output:"User"`
I didn't know if anyone had any links to a site or document that might explain this more, from the examples I can learn enough to use it. However, I would really like to fully understand it.
Thanks for your time!
Tags are nothing but strings, they don't have any meaning per-se.
Libraries can use reflection to introspect struct fields and interpret their tags. See reflect.StructTag.
In your case, gorest parses the following tags on Services:
root
consumes
produces
and these on Endpoints:
realm
method
path
output
input
role
postdata
Their meaning is described in gorest's documentation.
These are gorest tags. See gorest wiki http://code.google.com/p/gorest/wiki/GettingStarted
Sorry if this sounds stupid but I'm really new to LiftWeb and just struggling with the basic stuff:)
So I have a parametrized site map entry in Lift's bootstrap. This should be for the view page of an object of type MyItem. The URL would be like: "/myitems/UUID".
Menu.param [UUID]("MyItemView", "MyItemView", p=>Full(UUID.fromString(p)), p=>p.toString) / "myitems"
This adds the sitemap entry correctly. If I go to "/myitems/NOT_AN_UUID", it will throw the "Invalid UUID" exception as expected. But if I go to "/myitems/UUID" I get 404.
I know that I need a view and a snippet class that takes UUID as parameter in order for this to work but I have no idea how to name these and where to place them.
Btw, how would one new to Lift learn something like this? From the hundreds of articles and samples out there I found many to mention more complex stuff but haven't seen any to mention a basic thing like this. Do you know any secret start-up documentation for human beings?
Update: To summarize in case all you see above is jibber-jabber :) HOW DOES LIFT LOCATE TEMPLATES/VIEWS/SNIPPETS FOR PARAMETRIZED MENU ENTRIES?
It was actually the obvious answer. The template name is obtained from the path and the snippet can be whatever you want as long as you call it from the template xml.
I need to get used to all this convention over configuration :) However it would be nice for someone to tell you what is the convention.
I searched the web for how to enforce srictfp in Scala but could not find any hint of it. There are some people complaining about it, but real solutions cannot be found. There is a bugtracker entry about it which is almost two years old. As it seems there is no elegant fix for it on the way I'm looking for workarounds.
My current idea is to set the appropiate method flag ACC_STRICT in the generated bytecode by myself somehow but I have no idea what would be the best solution to do so. A Scala Compiler Plugin comes to mind or just hacking flags in a hex editor. Maybe someone faced the same challenge and can tell me his or her solution?
You could add a post-processor in your build process that would add the strictfp modifier to the generated class (i.e. setting the ACC_STRICT flag as you say).
You can implement such a post-processor using Javassist for example. This could look like this:
CtClass clazz = ClassPool.getDefault().makeClass(
new FileInputStream("old/HelloWorld.class"));
CtMethod method = clazz.getDeclaredMethod("testMethod");
method.setModifiers(method.getModifiers() | Modifier.STRICT);
clazz.detach();
clazz.toBytecode(new DataOutputStream(new FileOutputStream(
"new/HelloWorld.class")));
You would then have to find a way to configure which classes/method need to be modified this way.
Scala has a strictfp annotation now:
#strictfp
def f() = …
