What's the difference between these two classes?

In suggester/suggestion.coffee:

module.exports.DeclarationSuggestion = class DeclarationSuggestion

  constructor: (name, type, symbol) ->
    @name = name
    @type = type
    @symbol = symbol

  getName: ->
    @name

  getType: ->
    @type

  getSymbol: ->
    @symbol

versus

in error/missing-declaration.coffee

module.exports.MissingDeclarationError = class MissingDeclarationError

  constructor: (symbol) ->
    @symbol = symbol

  getSymbol: ->
    @symbol

fix authorship that says Fresh Account

Automatically include `import` statements for imported class and method symbols

Given a snippet that has an undefined symbol (like ArrayList here),

public class Example {
    public static void main(String[] args) {
        ArrayList<String> stringList = new ArrayList<String>();
    }
}

Search through the original code from which the snippet was made, and find the line with the import statement that defined that symbol. Add this line to the code example, so that it looks like:

import java.util.ArrayList;

public class Example {
    public static void main(String[] args) {
        ArrayList<String> stringList = new ArrayList<String>();
    }
}

assuming that ArrayList was originally imported from java.util.

Tools

Detect an undefined symbol using our existing def-use analysis. Then resolve which imports define it. I'm not sure the best way to do this. One way is to search through the import statements by visiting the parse tree, and just look for one that defines that symbol.

Aside from the duplicate handshake start, does this look like a reasonable example result to you? I cannot tell if it stopped prematurely

      return null;
    }

    public AnonymousClass3 getAcceptedIssuers() {
      return new AnonymousClass3();
    }

  }

  private static class AnonymousClass1 {

  private static class AnonymousClass3 {

  public static void main(String[] args) {

    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, new TrustManager[]{(new Tm())}, null);

Support multiple data replacements on the same line

Currently, multiple replacements works if you choose the later arguments first and then move on to earlier arguments. It doesn't work if you choose earlier arguments first (the labels and replacements get all jumbled---red marks appear in the wrong place and the replacements blend together).

Insert data for complex data types

We currently offer two ways to define undefined symbols: by including the code that defines it, or by substituting in the concrete value of that variable.

This substitution works fine for primitive data types. For example, changing

int i = j + 1;

int i = 1 + 1;

after it was detected that j held the value of 1 during some execution.

This doesn't work well when we want to substitute in concrete data for complex data types. For example, if we have a line that says

String title = book.getTitle()

what concrete data could we set book to? There are at least two options:

Option 1

The first option: find a call to the constructor of that object somewhere in the dynamic execution history of that variable. Put that constructor right above the line where the undefined symbol appears:

Book book = new Book("Moby Dick", 423);  // This line is added
String title = book.getTitle();

While this works well when all of the arguments to the constructor are primitive data types, it might get complex when some of the arguments are complex data types.

Option 2

The second option: create a mock class that returns just the values accessed during a recent execution of the program, and append it to the top of the program.

class Book {
    public String getTitle() { return "Moby Dick"; }
}

This has the benefit of ripping out entire classes that might contain irrelevant details. We might actually want to support both methods.

This option has the disadvantage that if an object returns a complex data type from one of its method call, that complex data type will also need a mock created for it. There might be a simple recursive solution to this for the typical case.

Tools

For option 1, for simple cases, it's probably sufficient to just use dynamic execution tracing tools that we've already used. Given an undefined type, just find all lines where a variable of that type is assigned. Save a reference to that line and offer it as an option to the user.

For option 2, use a parse tree with def-use analysis results to find all lines where a property or method is getting called on an object symbol. Then look at the results from dynamic execution of what the property or method evaluates to at that time. Create a list of the methods and properties accessed and the values they returned.
