The first step of the distributed-haskell tutorial is to
stack new
in a fresh directory. But if I try that, I get:
Missing: PACKAGE_NAME
Usage: stack.exe new PACKAGE_NAME [--bare] [TEMPLATE_NAME]
[-p|--param KEY:VALUE] [DIRS] [--solver] [--omit-packages]
[--force] [--ignore-subdirs] [--help]
Create a new project from a template. Run `stack templates' to see available
templates.
I guess the tutorial is written for another version of the stack tool. Or that the authors of the tutorial have forgotten to mention their default settings they use. Something like that.
So, the question remains - in order to continue following that tutorial - which of the available templates am I supposed to use?

I have an Ionic app running with the basics of Ionic and running it in the browser by doing ionic serve, but I want some new stuff and run it trough the grunt serve command, also has the feature for JSLint, I am already using this scss this: https://github.com/diegonetto/generator-ionic/ and I see that have everything I want, how do I install that in my project?
Take into account that my project is almost done, I have almost 85 % already done.
Is this the part I need to follow up:
Upgrading
Make sure you've committed (or backed up) your local changes and install the latest version of the generator via npm install -g generator-ionic, then go ahead and re-run yo ionic inside your project's directory.
The handsome devil is smart enough to figure out what files he is attempting to overwrite and prompts you to choose how you would like to proceed. Select Y for overwriting your Gruntfile.js and bower.json to stay up-to-date with the latest workflow goodies and front-end packages.
does this will bring some complications ? is there something else I need to know ?
I use the same generator and enjoy using it. With that said, I would not recommend starting to use a generator until you've made a complete backup of your project.
Even then, I'd recommend creating a brand new project using the generator then migrating your existing code into the newly generated project. While migrating, you should be modifying your code to match the generator conventions as you go. This gives you the most control and will make sure that you learn the conventions of the new project structure. Upgrading instructions are really meant for people who already use the generator and are just upgrading to a new version of the generator. They are not applicable to you.
First of all sorry. i know this would be a silly question, but i am very confused. and need an answer.
Question
I am making a project in sails.js.After running the "sails new myNewProject" command when i looked into the default modules that are formed i could not find the api/adapter in it.
so, i would like to know whether this adapter is created automatically or we will have to create it manually??
Thanks.
The api/adapters directory is not created by default on new projects.
If you need to build a custom adapter, you can start with sails generate adapter myAdapterName, which will create the api/adapters folder for you along with boilerplate files for the new adapter under api/adapters/myAdapterName.
If you're just looking to use one of the existing adapters like sails-mysql, you don't need the api/adapters folder at all. Just use npm to install it in your project:
npm install sails-mysql
A list of more available adapters is here.
Alright, so just a disclaimer I suspect this question will be a duplicate of another question however I'm not even sure what to search for.
I have never used Eclipse or Golang before and am attempting to get a basic hello world application to work.
I have installed the goclipse plugin, created a new go package and go command source file. From what I have read to run a project in Eclipse you right click the package, select Run as then set the run configurations. The problem occurs when I attempt to select the go package as none shows up and if I leave it blank it throws a 'Go package not found' exception.
Thank you for any help you can provide.
EDIT: Upon the answers advice I have decided to go with the basic command line, however a friend did also recommend LiteIDE. I will "assume" tmichels answer is correct in regards to getting Go to work within eclipse.
If you don't use the GOPATH environment variable and you don't put your project folder under $GOPATH/src the compiler won't find it. As I see it goclipse lets you skip the GOPATH entirely but in this case you have to put your code under the src directory that you can see in the Project Explorer. See the related section of the goclipe documentation.
Although I think you make your life harder by using a full-fetched IDE for go development. Just use the command line tools. And it has the added benefit that you will actually understand what's going on (IDEs hide this from you).
So for building you can use go build or go install. The latter will copy the binary to your $GOPATH/bin directory. For running test just call go test or go test path/to/package. There is a hidden gem in the go tool: when you are working with multiple packages in the same directory you can use go test ./... to test all of them at once. This also works with other go commands.
I have downloaded and started the community version of SFSx2. I read everything on their documentation page:
http://docs2x.smartfoxserver.com/DevelopmentBasics/introduction
Which unfortunately only talks about flash client side code. Nothing about the corresponding server side code, nor about html5 client side which I need.
I downloaded the HTML5 examples, which took me a long time to find (they are here: http://www.smartfoxserver.com/download/get/140 )
None of the examples work, as they can't connect to the server. Presumably, this is because the examples only supply client side code. There are no instructions supplied on how to install or run the examples.
I can find no mention on the smartfox documenation on the following:
1) what language is used on the server side. One assumes its java.
2) how does one deploy java code to the smartfox server? I cant find any mention of this in the docs.
3) how does one find and install the server part of the client side examples (which are Tris, GameLobby, BuddyMessenger, AdvancedChat).
I applied to be allowed to post on the smartfoxserver forums, but no reply yet.
I also found it hard so I share what I've found out.
The server extensions are written in Java. I used Eclipse JUNO to write my code.
You can download Eclipse here. http://www.eclipse.org/downloads/
You export the extension in jar format from eclipse into you extension path. The name of your file has to end in 'extension' eg MyFirstExtension.jar otherwise sfs2x wont recognize it. Your extension path will be something like this: C:\Program Files\SmartFoxServer2X\SFS2X\extensions\MyFirstExtension\MyFirstExtension.jar if your working in windows.
You will find docs on JAVA API here. http://docs2x.smartfoxserver.com/api-docs/javadoc/server/
This is a link to the basic example code: http://www.smartfoxserver.com/download/get/120
Unzip the content into the [SFS2X_install_folder]/SFS2X/www/root/examples folder, overwriting the existing file. Run the index.html file, then navigate to another index.html to open the example. Run the sfs2x-standalone.exe first of course(see below). If you followed the 'server configuration tutorial' on smartfox website and changed the server ports, the examples wont work. Leave the ports alone until you start to understand the server.
This is a link to the flash example code: http://www.smartfoxserver.com/download/get/108
You will find the example code for apps mentioned above. They are written in Adobe Flash Builder and Java extensions. I don't know if there is any code for HTML5 but the Java server code and AS3 is there.
I also found that using the standalone server was the way to go rather than using SFS2x as a service. c:\program files\smartfoxserver2x\sfs2x\sfs2x-standalone.exe. Using the exe gives you the command prompt window. You can use the window for debugging and see the state of the server when it starts.
Most of the examples should work without creating extensions but to create an extension out of source examples:
Create and setup a new project in your Java IDE. You will have already set up a workspace.
Copy the content of the /source/server/src folder to your project's source folder.
Add SFS2X Libraries. Go to properties of the project -> Select Java Build Path -> Click Library Tab -> Add external jar. Add 'sfs2x.jar' and 'sfs2x-core.jar' from C:\Program Files\SmartFoxServer2X\SFS2X\lib folder. To create the extension, export jar file to extension path. Restart server.
Another problem I had was the Java Version I was using. I had to use Java1.6 with my version of sfs2x when writing extensions. This was trial and error as there was no documentation. There may be a newer version out now.
I had to copy all the server source into eclipse to try and understand how things were done. It was a way of having all the code in one place. There was a lot of trial and error as getting help is hard. I eventually accomplished what I set out to achieve. Good Luck.
SmartFox Server is easy to use even with extension. documentation Give try to Nuggeta solution for game development too. No extension needed at first. This is optionnal.

I tried to post this over on the Eclipse Pulsar site, but it doesn't seem to want to give me access, so I thought I would try over here.
All I'm trying to do create a basic "hello world" application to test on multiple mobile phones as a proof of concept. I downloaded Eclipse Pulsar and the Samsung SDK (though I have this problem with any SDK) and I created a new MIDlet Project and ME MIDlet and selected the 'hello world' wizard and the resulting code produces these errors:
"the import org.eclipse cannot be resolved" on all of the imports.
I know I'm missing something basic, but I would have expected org.eclipse to already be on the build path. I tried adding eswt-converged.jar as and external JAR to the Libraries on the build path which fixes the import errors, but this seems like a hack and causes other problems.
So my question is: What step have I missed in creating the Project/MIDlet and is there a how-to online somewhere that gives examples on this stuff?
Thanks!
I think you are trying to create a "new eSWT Midlet". eSWT is a new UI toolkit that is not supported by most SDKs. Try using one of the other templates, something like Splash Midlet Template should be simple enough.
