Like firebug's console,I can type in the scripts directly.
Is there a similar place in eclipse out there?
Or do I install some plugin to have the feature?
You can use the Display window to type in code snippets, set variable values and evaluate whilst debugging.
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.jdt.doc.user/reference/views/display/ref-display_view.htm
The "watch" view can be used to execute simple snippets of code.
In some circumstances, I use the groovy shell (in a separate window) to check how a code snippet will behave. It isn't practical when complex data structures or library classes are involved, but for a respectable number of cases it works very well.
You can use the Expression and Display views. There's a set of excellent free video tutorials on the Eclipse debugger that you can see here. The aforementioned views are talked about in lesson 3.

I'm looking to improve my own productivity by trying to figure out how to provide cmd+click functionality for variables declared at runtime. I work with a library that allows you to register objects to it at runtime to be accessed later — it would be great if I could cmd+click to definitions of these! How do you think I could achieve this? I'm open to any ideas. Thanks!
Edit:
Thoughts I have so far inspired by feedback from various Slack communities:
There is no such thing as 'runtime' when providing functionality in IDEs
We need to be able to teach the IDE about what definitions to expect. Whether this means writing an extension to use the VS Code API specifically for my use-case, or otherwise working within a system that generates files that the IDE already knows to look for, which allows it to connect the dots and provide the precious peek / goto definition functionality
Edit:
I'm starting work on a VS Code extension that reads a dotfile for configuration — I'll share what I find out as I go!
I was hoping to find a way to automatically generate some code based on existing code.
The actual functionality would be very similar to javadoc or in this case IDLdoc or to automatic get/set functions.
I want to create some generic code based on some already listed parameters.
How do I accomplish this within eclipse?
I think an example would be best, so here is what I would like to accomplish:
keyword1: stuffIdontCareAbout, $;comments
keyword2: otherStuffIdontCareAbout, $;more comments
keyword3: lastStuffIdontCareAbout $
What do I need to do in eclipse so that I can have eclipse quickly parse the above block and output the following for another part of the code?
KEYWORD1=inp_keyword1, KEYWORD2=inp_keyword2, KEYWORD3=inp_keyword3
Thanks
My usual knee-jerk response is to suggest that you use JET as that what it's designed for.
For this specific case, however, you might be better off just writing a simple popup action (use the new plugin project with the popup action template) that parses the properties file (looks simple enough to do in Java) and writes out the target code to another file, the console or, if you're clever, back into an existing file in the right place.
Once you have the plugin generated for you with the template, the rest should be simple Java.
I am working on writing an IDE for Scala and need some help. I would like to implement coding assistance so that I could present a list of options when a user presses a period (".") or a space (" "). e.g. if projects is a List, as soon as user types "projects." or "projects ", I would like to show all methods of scala.List that he could use (regular IDE stuff). I know that scala.tools.nsc.interactive package provides this capability, but I am unable to figure out how to do it. Besides, it seems that the interactive package would use REPL and would be slow for this purpose. Is that a fair assumption, and if yes, are there any alternatives?
Also, is there a way I could get a call reference tree for a literal/ method (where all is the method referred to in a code base) ?
Thanks and Best regards

Well, your best bet is going through the same set of links I provided in answer to this question, even though the questions are different.
Yes, the presentation compiler under scala.tools.nsc.interactive is where the reusable functionality would be.
The presentation compiler is used by Eclipse and ENSIME. May be ENSIME itself which in addition to providing emacs support also provides a server as a backend for an editor would be a good avenue.
The presentation compiler is not slow. It was designed from the ground up to provide good performance for Eclipse and it has largely delivered on this goal.
For some of the presentation compiler capabilities, see scala.tools.nsc.interactive.CompilerControl.
For another project using ENSIME, look at Daniel Spiewak's plugin for jEdit.
I have some big documentation to do that will contain pieces of code I'd like to give the conventional "coding language" syntax highlighting. I've searched the styles feature to do such a thing, but there is no way to do that (in fact I could only found a forum where people were fighting about adding this feature or not, but this is not the point).
There is an abandoned extension for OpenOffice, but using it freezes my installation of OpenOffice.
What's the easiest way to do this? Should I try to recompile the extension and debug it (although I'm already having a hard time compiling another Java project), or maybe I should use a macro? How to implement this?
One possibility is to use one of the many code to html tools out there and then include the html in your OpenOffice document (using "File..." on the Insert menu).
One possibility is highlight. Vim has a :TOhtml command that will convert the current file to syntax highlighted html using the current colour scheme. I've not tried it, but this looks promising. There are also a few online ones, such as this. I'm sure there are a great many other options.
Being really new to wx, I'm wondering if there is an IDE (especially for Linux) which would help me lay out a frame or dialog or whatever just to help me see what I'm doing. That means also creating the code for those changes.
I remember way back when using resource compilers for OS/2 and Windows that produced binaries that would then create the window, and was hoping for something similar (though obviously not binary if wx doesn't support that).
I use wxFormBuilder. It is written in wxWidgets, so it works on Linux quite well. It can generate C++ code or XRC files. Make sure you understand its philosophy, and use it like this:
generate C++ code for the GUI
don't edit the code wxFormBuilder generated, but create new files
in new files, derive new classes from the classes it generated
implement event handlers in you own class (wxFB creates virtual function for each event handler you wish to use)
I usually name the wxFormBuilder generated classes/files like, for example, MainFrameGUI, and one with implementation (derived one in which I write all my code) would be just MainFrame. This enables you to change the visual layout and regenerate C++ files from wxFB at any time without overwriting your code.
DialogBlocks works quite well for me, although sometimes you need to edit the code to fix errors manually. It has a property editor that seems advanced enough.
Just another options is wxGlade. It does not have the that much features as the others mentioned seem to have, but it works just good enough for me to not daring to switch.
I use Code::Blocks IDE from http://www.codeblocks.org which has
- built-in GUI editor
- Cross compilable, so you can use it under Linux, OSX and Windows.
But I still use wxFormBuilder with it instead of built-in wxSmith editor. But they are compatible with internal wxSmith.
For windows you've got "wx-devcpp" which is Blodsheed Dev C++ with some addons providing what you looking for
