My goal is to create (find if exist) a tool which can produce swift files from templates.
For example, let’s say I need to create new ViewController with UITableView. It should be based on MVVM architecture with dependency injection. Let’s name this View “PersonsList”.
So, for this task I need to produce:
PersonListViewController
PersonListViewModel
PersonListViewModelProtocol
PersonCell
VM for cell and protocol for VM
Lots of files.
I want to say to my tool something like that
create tableview-template Person
and as a result get generated files. Files should contain empty implementation of each classes.
How should I do that? I am thinking about simple console app but I don’t know which language I should use. Maybe there is a better idea? Maybe there is a ready tool? Any help? :)
You could manually create the templates yourself and then write a short script (in Python / bash / swift etc) that goes through and replaces keywords with arguments you've passed in.

I need to implement a custom ResultHandler but I am confused about how to actually integrate my custom class into the software package.
I have read this: http://elki.dbs.ifi.lmu.de/wiki/HowTo/InvokingELKIFromJava but my question is how are you meant to implement a custom result handler such that it shows up in the GUI?
The only way I can think of doing it is by extracting the elki.jar package and manually inserting my custom class into the source code, and then re-jarring the package. However I am fairly sure this is not the way it is meant to be done.
Also, in my resulthandler I need to output all the rows to a single text file with the cluster that each row belongs to displayed. How tips on how I can achieve this?
There are two questions in here.
in order to make your class instantiable by the UIs (both MiniGUI and command line), the classes must implement our Parameterization API. There are essentially two choices to make your class instantiable:
Add a public constructor without parameters (the UI won't know how to set your parameters!)
Add an inner static class Parameterizer that handles parameterization
in order to add your class to autocompletion (dropdown menu), the classes must be discovered by the MiniGUI/CLI/other UIs. ELKI uses two methods of discovery:
for .jar files, it reads the META-INF/elki/interfacename service files. This is a classic service-loader approach; except that we also allow ordering instances.
for directories only, ELKI will also scan for all .class files, and inspect them. This is mostly meant for development time, to avoid having to update the service files all the time. For performance reasons, we do not inspect the contents of .jar files; these are expected to use service files.
You do not need your class to be in the dropdown menu - you can always type the full class name. If this does not work, adding the name to the service file will not help either, but ELKI can either not find the class at all, or cannot instantiate it.
There is also a tutorial on implementing a custom result handler, but it does not discuss how to add it to the menu. In "development mode" - when having a folder with .class files - it will show up automatically.
I'm trying to solve possibly simple problem, in my 'views' directory, in typical Play framework setup, I would like to group my templates (*.scala.html files) into groups, possibly using another folder for each group, eg. I would like to have customers folder with the following files in it:
createForm.scala.html
editForm.scala.html
list.scala.html
So far so good but when I try to access that view reference from my controller (eg. Ok(views.html.list(..)) -> Ok(views.customers.html.list(...)), I get an error:
object customers is not a member of package views
Is there any best practice/receipe on how to work with multiple views, how to gather them into groups and then how to use them in other views or controllers.
Thx in advance.
The way the template engine works is that a template defined as:
/views/application/index.scala.html
Will be turned into a class:
views.html.application.index
So basically views.html is always kept as a prefix. Cf. the Play template documentation.
In your case that means it should be
Ok(views.html.customers.list(...))
If you have a closer look at the target directory, you'll see how views are compiled and the packages are made:
Ok(views.html.group.view())
You can also import like this:
#import views.html.group._
//...
Ok(view())
Let's say i have a xml file with a tag named which contains the number of fields i want to show in my tableView and in another xml file i have the information to be displayed in that tableView.
The question is : Should i create 2 different file in my project (xmlparse1.h and .m + xmlparse2.h and .m) or should i just put all my code in 1 (xmlparse.h + .m) and differenciate which file i am parsing at the moment with a bool or something like that in the code?
I am developing an iphone app on Xcode 4.3 mac os x 10.7.4 if this might change
EDIT: 1st file :
<MenuPrin>
<humidite>82,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0</humidite>
<tempmoy>
189,124,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700
</tempmoy>
</MenuPrin>
2nd File :
<Instal>
<nbrField>2</nbrField>
</Instal>
So it looks like this. So, since nbrField is 2 I would take the 2 first value from tempMoy and humidite and show them in a tableView.
END OF EDIT
If how you're parsing is similar in both instances, to add two sets of files that do effectively the same thing would be extremely inefficient and considered bad practice. It makes a lot more sense to create a parser that can handle the two different files than to write two parsers that can only handle a specific file each.
To more specifically answer your question, I would determine which file you are parsing and behave accordingly, whether you do this with a bool or something else is up to you.
EDIT: Here is the idea that just popped into my head, so if for whatever reason this wont work for you(Like I said its been a while), or someone has a better idea, I'm all ears. You could still have a set of files(.h and .m) that contain the definition of your parser. Your parser could contain within it a two variables of type Object1 and Object2 which are built in such a way that they resemble the data structure that you need to store what you parse once for your first type of file, and a different definition for your second type of file. This way when parsing once you determine which file it is you are reading, it just changes which of these two objects you write into. There are also plenty of variations for how you could set this up, and I can also think of a few cases for what you might be trying to do where this might not work, but there is the idea regardless.
If you think that the two sets of files approach is better for the application you are trying to write and makes more sense to you, given what has been discussed in the comments, it isn't necessarily a bad idea.
In case if u want to create two table view in one view u need to create a single .h & .m file...If u want to create individual table view u need to create two .h & .m...
Try TBXML parser...that is the easiest way and less memory usage for xmlparsing...
I can't find a good answer to this simple question:
Where can I add my i18n files in a GWT project ?
I see two solutions:
- create a module and add all i18n files for this module in this module
- create a complete different structure to put all i18n files (no matter what module) in the same directory (and so, easy to create a new language)
My feeling is that the second approach is better but in gwt samples, it's the first approach which is generally used.
And you, what do you do with yours i18n files ?
Thanks
1) Create a separate package in your module. Dump all message files there along with the property files.
2) As a best practice create a base message class and EXTEND other message interfaces from the base one. You can reference base message class in code and depending on which instance of message class you point too, your actual value will change.
Another approach, create a new i18n module and inherit that in your actual model.
1) Allows all messages to be in one place.
2) Easy to hand over to localization people for translation.
I usually put the i18n files (*.properties) in the same package as the Constants (or any other i18n related class) derived interface that's using them (less hassle with setup) - usually the package is named i18n.
I'm trying to come up with a way to make it easy to switch out our "mock" data services and our live ones. Basically, we'll have live servers with real web services, but for whatever reason, a developer may want to load data from static files (file urls).
I figured I would solve this problem by creating categories that override the methods that fetch the data, thus leaving original code untouched (it has no concept of the "mock" data). I don't want to litter my code with #ifdef.
I can put an #ifdef at the very beginning of each file that has categories in it, and I can set a custom flag in the configuration settings, but I'd rather just have a way to include or exclude the files depending on the configuration. Is that possible? How do you solve this problem?
See http://lists.apple.com/archives/xcode-users/2009/Jun/msg00153.html
The trick is to define EXCLUDED_SOURCE_FILE_NAMES in the configuration you want to exclude the files from, and set the value of that custom build setting to a list of the file names (or a pattern that matches those, and only those, file names).
I would recommend creating two targets one of which has the mock categories included and another one which does not.
When you want to test, just build the target containing the mock categories. Everything else can remain identical.
If you would like to add a file but do not wont to compile it. Go to (for all your targets) project>build phases>compile source and take out the file that you do not want to compile.
