At work we're currently using an IDE called PHPEdit, however we're looking to move to another primary IDE, we've been looking at Aptana Studio 3 based off eclipse.
A very nice feature of PHPedit was you could create new methods by clicking a little tool tip under new methods.
For example you could type
$data = $this->model->getData();
and if the function getData() didn't exist you could click the word "getData" and get a little option to create the method, then it would automatically create it in the relevant model and if you passed any params through it like $var, $var, then it would auto set them up as well.
I was wondering if such feature is available or if anybody knows of one as I'm not overly sure what to be searching for in any documentation as I don't know what this is actually called.
Many thanks!
AFAIK eclipse PDT does not have exactly what you want.
You can have a look at Linux programming editors and meybe even checkout Jetbrains
While you are at it, have a look at this question
Eclipse already does that.
I just typed following code in my open editor.
Intent intent = new Intent()
// some code to init intent
String data = getData(intent);
And of course it cried that getData() does not exist. When hovered with mouse, it gives options to create getData(Intent). And when I choose to create this method, it gives following:
protected String getData(Intent intent) {
// TODO Auto-generated method stub
return null;
}

I wanted to check Java 8 integration with Eclipse Luna so I downloaded the M7 Luna from eclipse.org.
After configuring the JDK to jdk8u5, I started some tests.
Let's say you have a nice Runnable like
Runnable r = new Runnable() {
#Override
public void run() {
System.out.println("foo");
}
};
If you select the
new Runnable() {
#Override
public void run() {
System.out.println("foo");
}
}
block and press Ctrl-1 (Quick Fix), you get the suggestion to change it to a lambda, resulting in Runnable r = () -> System.out.println("foo");, which is pretty cool.
But a nicer thing whould be to actually help creating lambda expression.
For instance, if you type Runnable r = | (with | being the cursor location) and press ctrl+Space (content-assist), I would have expected to find a "create a lambda expression from this functional interface" option in the displayed popup. But nothing new is available.
Do you know if this will be implemented in the future ?
I think it might have something to do with the templates (Java/Editor/Templates in preferences) but I actually never experimented with them.
Providing good proposal right after the = is rather tricky as almost everything could be placed on the right hand side of an assignment.
Even the old way of implementing a function using an anonymous inner class was not proposed right after the equal sign. You had to type the four characters new␣ before the suggestion came up. And four characters is exactly what you have to type to create a lambda, ()->, but at this place proposing the creation of a lambda makes no sense anymore as you have already created it.
So proposing a lambda would require lifting its priority compared to other proposals to appear right after the equal sign but it would still have rather limited benefit. You had to press crtl+space unless you use automatic menu popup, then select “create lambda” to just get either the four characters ()-> or something like name-> inserted whereas the parameter name(s) are likely to be changed after the proposal is inserted.
For an inner class, read method overriding, it makes sense to propose parameters as you have to repeat all parameter types exactly, but for a lambda where you can omit all the bulk the saving is very limited.
So I don’t expect a proposal of lambda creation to ever appear in the list.
Currently I get this result with Eclipse auto completion.
System.console().printf(format, args)
Of course, Eclipse shows the parameter types as popup, but I want the types to be displayed in front of parameter names too. Like this.
System.console().printf(String format, Object ... args) // `String`, `Object` inserted automatically.
Can I configure Eclipse to show the parameter types too?
Of course not. Eclipse auto completion only suggests valid syntax, while your demand is not valid java code.
An alternative for you might be to open the "Declaration" view or the "JavaDoc" view. Both will always show the declaration/JavaDoc of the currently selected element while you are typing. Therefore you could see the method declaration/javadoc when writing that method call.
Update
Whoever came across this old question. You can use eclipse code mining now:
parameter name hint for Eclipse
I am developing an eclipse plugin that runs code violation checker on the difference of two versions of a file. Right now I am using diff.exe to get the difference between the two files. But as diff.exe is an extrenal app, I realized that its better to use eclipse built-in compare tool to get the file difference.
So I used org.eclipse.compare and reached up to this point:
public static List<Patch> compare(String old, String recent) {
try{
IRangeComparator left = new TokenComparator(old); //what exactly to be passed in this constructor, a file path, a literal value or something else?
IRangeComparator right = new TokenComparator(recent);
RangeDifference[] diffs = RangeDifferencer.findDifferences(left, right); // This line is throwing NPE
//..
// Process RangeDifferences into Collection of Patch collection
//..
}catch(Exception e){}
//Returns a collection of file differences.
return null;
}
Now the problem is I am not sure what exactly to be passed in the constructor TokenComparator(String). The document says this constructor Creates a TokenComparator for the given string. But it is not written what exactly to be passed in this constructor, a file path, a literal value or something else? When I'm passing a file path or a string literal I am getting NullPointerException on the next line of finding differences.

Someone please tell what is right way to proceed.
If the question is What value the token comparators constructor takes then the answer is it takes the input string to compare. Specified in javadoc here http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fcompare%2Fcontentmergeviewer%2FTokenComparator.html
TokenComparator(String text)
Creates a TokenComparator for the given string.
And the null pointer yo are getting is because in function isCappingDisabled it tries to open the compare plugin which seems to be null. You seem to be missing a direct dependency to the plugin "org.eclipse.compare.core"
The org.eclipse.compare plugin was never meant to be used in standalone : many of its functionalities require a running instance of Eclipse. Furthermore, it mixes core and UI code within the same plugin, which will lead to unexpected behavior if you are not very careful about what you use and what dependencies are actually available in your environment.
You mentionned that you were developping an Eclipse plugin. However, the NPE you get indicates that you are not running your code as an Eclipse plugin, but rather as a standard Java program. In an Eclipse environment, ComparePlugin.getDefault() cannot return null : the plugin needs to be started for that call to return anything but null.... and the mere loading of the ComparePlugin class within Eclipse is enough to start it.
The answer will be a choice :
You need your code to run as a standalone Java program out of Eclipse. In such an event, you cannot use org.eclipse.compare and diff.exe is probably your best choice (or you could switch to an implementation of diff that was implemented in Java in order to be independent of the platform).
You do not need your program to work in a standalone environment, only as an Eclipse plugin. In this case, you can keep the code you're using. However, when you run your code, you have to launch it as a new "Eclipse application" instead of "Java Application". You might want to look at a tutorial on how to develop Eclipse plugins for this, This simple tutorial from Lars Vogel shows how to run a new Eclipse Application to test an Hello World plugin. You will need a similar code, with a menu entry to launch your plugin somewhere (right-click on a file then select "check violations" in your case?).
While typing in Eclipse (Java) I often have the problem that when I begin to type accessors, the caret jumps down to the beginning of the constructor definition. So in a document like this:
private int mSomeInt;
public
in|public MyClass(){
}
I would like to manually type out the accessor (getter/setter) for mSomeInt, but when I press space after 'public' above, the caret jumps to the beginning of 'public MyClass'.
I often type complete lines to look up and find my methods jumbled with the constructor (like above).
Any help would be appreciated.
Note - this isn't only with accessors but rather any access modifiers that I define before the constructor or another method.
Edit
After unsuccessfully trying Deco's solution below, I've managed to narrow it down a little further.
The problem only happens if I have all the blocks in the file in a collapsed state (ctrl+shift+numPadDivide). I can see the problem is now that the new access modifier I type is then (quickly) collapsed into the below method. i.e. Eclipse is actually taking the first accessor modifier and collapsing everything from there, even though my intention is actually to write a new method.
The only solution I've been able to find is to only edit the source with all the 'fold' elements unfolded.
Under Window -> Preferences -> <Language> (e.g. Java) -> Editor there is a Content Assist menu item where you can configure auto completion and caret placement as well as auto-activation of it and the delay it uses.
Edit:
After your update to the original question I was able to successfully replicate this in Eclipse Indigo. When you have all of the code blocks collapsed it looks like Eclipse assumes that the code you are writing needs to be in that block (rather than as a variable declaration). I'm not sure if this is expected behaviour or not - but the only way around it I've found is to edit the code with the main block open, and then close it after the fact - or turn folding off altogether.
From what I can tell there are various folding plugins/addons that you can get for Eclipse which override the default behaviour and might function better? A quick Google search will be able to get you a list of them quickly.
I'd probably also suggest posting this as an issue on the Eclipse support site for their official answer.
Unfortunately this issue still exists for me in the latest Elcipse version (Kepler).
As the issue only occurs when the document is 'folded', the work around this is to either disable folding in the editor - or disable folding on 'Members' from the :
Preferences -> Java -> Editor -> Folding
Im currently doing a lot of testing with JPA entities, where i have to keep calling the setter methods on the entity that looks something like this :
myEntity.setXXX(value);
myEntity.setYYY(value);
myEntity.setZZZ(value);
Is there any magic shortcut or menu in eclipse IDE to generate all the setter-method-calls that starts with "set", like those displayed in the ctrl-space (auto completion) popup (i think the inherited methods from Object are not being shown at popup) ?
So im imagining something like :
i type myEntity.set
and myEntity.set* are generated right away
Im a lazy programmer and currently using Eclipse Helios IDE.
Thank you !
Edit
Im not looking for source -> generate getter and setter, because that would helps me in generating the methods itself. Generating the method calls is what i want to achieve.
I have found the answer (I was always searching for this thing)...
The easiest way is to expand the class members in the "Package Explorer", sort them by name, multi-select all the setters, and then you have in the clipboard all the method names...
;-)
I like #Oscar's answer. It does lead to some cleanup though.
When I paste from the clipboard, I get something that looks like this:
setOne(int)
setTwo(String)
In order to clean this up, I first add semicolons with this search/replace regexp:
search = (.)$
replace = \1;
Then I add the getter calls (assuming incoming data object is named "data"):
search = s(et.*)\(.*
replace = s\1(data.g\1());
This doesn't handle multiple arguments in a method call...
you can use the outline at right side. There you can sort alphabetically or by declaration order using the toolbar button of the view.
and then you can filter out non required this.
From here also you can copy..all setter functions or getters functions names...
There is eclipse plugin to do that. The name of the plugin is **
FastCode
**. There are so many templates. Among those there is template to generate code for create object of the class and all setters method.
Source --> Generate Getters and Setters...
You can also get at it via the Quick Fix command (Ctrl+1) when the cursor is on a property.
EDIT
If you are simply looking for a faster way to copy properties from one object to another I suggest that you look at using reflection. I think this path would be much easier long term then generating the same-looking code over-and-over.
Commons BeanUtils can take away some of the pain in writing pure reflection code. For example, copyProperties takes a destination bean and either another bean or a Map as the source.
