gap-eclipse-plugins's Issues

SubType constructors don't complete constructor args for abstract types

Take the code
org.assertj.swing.fixture.AbstractContainerFixture.panel(GenericTypeMatcher<? extends JPanel>)

The actual completion result with the

    fixture.panel(new GenericTypeMatcher<JPanel>()
    {
    })

even though I selected the two argument constructor.

Recommenders timeout

The recommenders becomes not responsive and timeout due to this proposal processes tries to find subtype of Object type as well. We need to eliminate java.lang.Object and other unwanted types from this processor.

java.lang.UnsupportedOperationException: Operation only supported in extended context

Gets the following error then either going through each computer one by one or adding or removing characters from completion string.

Subtype completions are duplicated and incorrectly qualified

Invoking subtypes for
List<String> list = new $

will result is duplicate subtype constructors, the same constructor is duplicated 3 times.

When selecting a constructor completion it ends up with a wrong completion. for example selecting ArrayList() will end up as List<String> list = new ArrayList.ArrayList()

No java8 completions on stream operations

		return typeSignatures.stream()
					.map(t -> Signature.getTypeErasure(t))
					.map(|)

No completions for second map operation.

qualified calls are identified as recursive

The qualified call annotation identify super qualified calls as recursive.

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) {
   chain.doFilter(request, response);
}

the qualified here is chain, this happens for any qualifier for example like super.

Lambda suggestions inside lambda it self

Stream.of("2").map(s -> $) or Stream.of("2").map(s -> {$}) still suggest lambda proposals.

Smart completions doesn't work well inside lambda statements

      ids.stream().map(id -> {
          return readXmls(id, $);
      }).collect(Collectors.toList());


private XML readXml(String id, Date after) {}

For this I would expect the smart completions provide me information related to the second parameter type Date.

Smart Type completions not working for constructors

Map<String, Integer> factories = new **HERE**
Select HashMap constructor doesn't complete.

The subtype completion is getting called even though it is disabled

The subtype completion is getting called even though it is disabled when completing method arguments.

Smart Enum timeout on interface type parameters.

Smart Enum timeout on interface type parameters. The smart enum proposals must have a timeout.

Duplicate lambda expression completions for overloaded methods

 AccessController.doPrivileged()

You will get duplicate lambda expression completions for each overloaded method.

Recursion annotations not show in vertical ruler when the method is a generics method

For example, the Line 14, 15:

When it comes to generics class like below:

public class BinarySearchTree<E extends Comparable<E>> {

    private Node root;
    private int size;

    public BinarySearchTree() {
        this.root = null;
        this.size = 0;
    }

    public void add(E e) {
        root = add(root, e);
    }

    private Node add(Node node, E e) {
        if (node == null) {
            size++;
            return new Node(e);
        }

        if (e.compareTo(node.e) < 0) {
            node.left = add(node.left, e);
        } else if (e.compareTo(node.e) > 0) {
            node.right = add(node.right, e);
        }
        return node;
    }

    private class Node {

        public E e;

        public Node left, right;

        public Node(E e) {
            this.e = e;
            left = null;
            right = null;
        }
    }

}

The annotations are missing too:

Recursive call gutter icons are shown in Intellij IDEA:

Duplicate lambda completions for Collectors.toMap(null, null)

No smart type suggestion at super constructor arguments

	public CosmicSourceContainer(IPath externalJarPath, JavaProject project) {
		super(null, externalJarPath, project, new $);
	}

Debugging The Eclipse Platform

@gayanper What should I do if I want to inspect code performing a specific operation(Like to inspect code responsible for a bug).
I tried many solutions like launching the workbench in debug mode, using Plug In Spy etc, but still I cannot pin point which part of the code is responsible for the operation.

For example I want to know which part of code is responsible for displaying the Help Contents in the toolbar like
WorkBench User Guide, JDT Guide etc.I have been able to find that this documentation is being supplied by org.eclipse.platform.doc.user plugin but I don't know which plugin is responsible for displaying the Help Section from the toolbar.
Although I think it is in org.eclipse.ui.help plugin.

I would like to know the workflow the developers follow to inspect code for the platform to simplify the process of bug fixing, code inspection etc.

After introducing the Recursion Markers line highlight is change

After introducing the Recursion markers the line number colors and line highlight colors are changed in the light theme.

No suggestions for some methods

Example:

Label label = new Lable();
VBox.setVgrow(label, |);

Enum proposals causing eclipse to freeze

when completing a code as below
new Thread(futureTask1).
eclipse freeze and the enum proposals timeout.

[feature] QuickFix for creating a stream out of a array

quick fix for created a stream out of an array.

project.getBasedir().listFiles()

Stream.of(project.getBasedir().listFiles())

[improvement] New quickfix for creating methods out of method references

Given a code like
return CompletableFuture.supplyAsync(this::mineForTests)

one should be able to invoke quick fix and create the correct method skeleton in the immediate enclosing type for mineForTests.

Static completions show reference results as well.

Static completion show returns of static methods where the target type appears as parameters as well.

Not working for methods invocations which has method overloading

Not working when there are overloaded methods like org.mockito.Mockito.mock(Class, String)

No Completions for Map<Long, Map<Long, List<Long>>> maps = of

With Map<Long, Map<Long, List<Long>>> maps = of one would expect to have guava ImmutableMap suggestions on the second invocation of smart completions.

Wrong lambda completion suggestion for java.util.Comparator.comparing(Function<? super T, ? extends U>)

Recursive marker doesn't distinguish between static and non static methods

Given the code

public class App {
   public void foo() {
     foo(10);
   }

   public void foo(int i) {
   }
}

the line foo(10) should not be annotated as recursive call.

[improvment] Switch to better AST scanning

This is needed when you are working with large classes (legacy code)

https://stackoverflow.com/questions/35841083/how-to-get-all-jdt-ast-statements-at-a-given-line-number

Don't suggest lambda completion when there is a completion token

No Smart Completion Support in eclipse 4.16

public static void foo() {
   setStatus($)
}

public void setStatus(Thread.State state) {}
