As an exercise my team is looking at learning functional programming. One of the factors to choose a language is its support in Eclipse. Any language with Eclipse plug-in is fine but what language offers the best free plug-in?
Bonus question: the best online/book tutorial for this language.
I don't know if it is the best, but it is evolving and improving fast:
Scala IDE (up to Scala2.8.1RC1 right now)
As for the best online Scala book:
Programming Scala (Creative Commons Attribution-Noncommercial)
But you will find other online sources in the SO question "List of freely available programming books".
Clojure is pretty well supported with the Counterclockwise plugin in Eclipse. Key features:
A nice syntax aware editor including rainbow braces
An integrated REPL
Dependency management orks reasonably nicely with Maven, other Eclipse plugins etc.
Debug mode works fairly well
I would go for Javascript, with Eclipse + Aptana plug-in and Secrets of the Javascript Ninja for a book with some nice advanced material.
Since nobody gave this answer I have to add it.
Groovy offers Java integration, Eclipse plugin and integration, and functional features. Many would argue that it's a scripting language but it's a complete language nonetheless. And it's obvious choice for Java junkies...
Python with PyDev plugin is another great option.
Erlide plugin for Erlang development on Eclipse.

I am learning Java and my IDE is Eclipse Mars. I was wondering if there was a way to create a GUI in Eclipse?
I researched it and the only half decent way I can find was pretty complex, any ideas?
Eclipse includes WindowBuilder, a "bi-directional Java GUI designer." Whether you have it installed in your Eclipse depends on which package you downloaded; if you downloaded Eclipse IDE for Java Developers then it's already included. If you got a different package, you can install WindowBuilder via these instructions.
Eclipse itself has only the coding function when it comes to GUIs.
If you really want to know your way around GUIs I recommend you learn it by programming it.
If you just want to try it out one time or start with easier lessons and then go into programming it yourself I recommend the IDE "Netbeans". It has a drag-and-drop kinda GUI builder implemented with which GUIs are very easy to implement.
Especially if your are just learning Java I recommend learning the basics in Java first, insert your functions into an easy to build GUI with Netbeans and later on go into fully programming GUIs.
Netbeans is also free and pretty much the same as eclipse. Maybe less customizable features, but for beginners and people who want to know how GUI works its perfect.
What is a difference between an IDE and Framework with respect to Java?
Basically :
The IDE is the software you use to develop ; for example, Eclipse is an IDE (code editor, debugger, build tools ... )
The Framework is a set of both libraries and best practices that help you not re-invent the wheel, and provide a set of guidelines on how to develop.
Quoting wikipedia, an IDE :
is a software application that
provides comprehensive facilities to
computer programmers for software
development. An IDE normally consists
of:
a source code editor
a compiler and/or an interpreter
build automation tools
a debugger
While a Framework :
is an abstraction in which common code
providing generic functionality can be
selectively overridden or specialized
by user code, thus providing specific
functionality. Frameworks are a
special case of software libraries in
that they are reusable abstractions of
code wrapped in a well-defined
Application programming interface
(API), yet they contain some key
distinguishing features that separate
them from normal libraries.
An IDE is an application used to write and compile code. A framework is generally a software component that someone else wrote that you can use/integrate into your own project, generally to avoid re-inventing the wheel.
A framework is a tool that is closely attached to the language you are using and usually extends upon or adds the the language features.
An IDE (Integrated Development Environment) provides automation support for the language you use with regards to syntax highlighting of keywords, errors, building projects, cleaning them, intgegration with VCS, etc. and usually provides default support for popular frameworks used for your language.
Java makes use of frameworks like Hibernate, Struts and Spring to extend the language and NetBeans or Intellij IDEA bring support for these tools to your Java project in a structured manor.
As per all answers I can come to a conclusion that Visual Studio is an IDE and .NET is a framework.
And also a framework(list of .dll) can be integrated into an IDE. Mean framework is a part of an IDE.
I have been reading about Scala for a while and even wrote some small programs to better understand some of the more exoteric features.
Today I decided to do my first "real project", translating some 60 lines of ugly Java code to Scala to rewrite it using the better pattern-matching features (why? because the Java version was becoming hard to maintain due to excessive combination of regex and conditionals).
About halfway through the editing process, Eclipse thew up this error:

I get the general impression that the Scala IDE in Eclipse is a lot buggier and less complete than its Java equivalent. Is this correct or do I just have a bad installation? Is there a better IDE for Scala?
I really like IntelliJ Idea Community Edition's Scala support. I've been using it from it's early days. I've also tested Netbeans and Eclipse plugins but I really don't like them that much. Especially all Eclipse Scala plugins are crap. I also tested Textmate Scala bundle, which is very nice but doesn't offer auto completion.
Here is my Scala Ide top list:
IntelliJ Idea Community Edition
Netbeans
Textmate (This is here, since I really like Textmate for writing Rails applications)
Eclipse
When you learn IntelliJ Idea keyboard shortcuts and add some live templates you can be very productive programmer. Furthermore, if you buy the Intellij Idea Ultimate Edition you can even share the settings with multiple computers or with your team.
What I suggest:
Download IntelliJ Idea Community Edition
Install the Scala plugin
Learn the keyboard shortcuts: Windows and Linux, Mac
Configure Live Templates when you get more familiar with the ide
The Eclipse IDE Scala support has not been great for some time, but is now receiving additional development effort alongside the introduction of Scala 2.8, and appears to be improving. For Scala 2.7 I have found the Intellij plugin to be in a better state.
One problem that both of these plugins have is that Scala itself is a moving target - Scala 2.8 has introduced additional syntax and structures to Scala 2.7.
From my own experience with Eclipse, using it for languages other than Java is never quite as good.
You might find this post of interest.
I get the general impression an IDE for a new, young, niche language is a lot buggier and less complete than a widespread, supported, mature language
Try Netbeans. Its plugins are generally of a simpler construction anyway, so should have less 'gotchas'
One point to make is that it is possible that people are still put off IntelliJ because they assume that the licence is expensive, especially if they are happy with Eclipse and are unaware of the Community Edition which is free and open source.
I cannot give any comparison with the other IDEs as I have always used IntelliJ, however the Scala support is certainly good, all things considered, and getting better.
We are using Eclipse Scala plugin at work and working with it is quite terrible. One cannot really trust reported errors inside IDE, runtime exceptions are the order of the day. Our best experience is with build from 25-11-2009.
At home I play with IntelliJ 9 and its Scala plugin and I find it much much better. I am newbie to IntelliJ but I am very impressed with all those little details which (once you get used to them) increase your productivity... a lot.
The drawback is in IntelliJ there is no compile-error reporting on the fly (at the time you're writing code) yet implemented and only Scala up to 2.7 is supported (2.8 by nightly builds only), but there are NO runtime exceptions while working with the IDE. I would recommend you to try IntelliJ, community edition at least.
I never really get on with IDEs at the best of times because they are usually pretty awful at actual text editing, but Eclipse's Scala plugin is particularly brittle to the point that projects "forget" that they are Scala after a while. Battling Eclipse seems to consume more effort than it saves. I just went back to my Emacs and sbt REPL in a terminal.
A light play with IntelliJ confirmed that it does at least do the job as a Scala IDE, but again I didn't care for its editor. It's also commercial software. However, if you are seeking a robust Scala IDE, this is perhaps where you should be looking.
What I have since settled on is perhaps perverse and not for the newcomer, but suits somebody who has definite opinions about their text editor. ENSIME is an editor plugin and server component that adds what you need from a Scala IDE to Emacs. It also claims support for vim, Atom, and Sublime, but I've not tested these. Occasionally it also has a bad day—obscure kinds of macros particularly confuddle it—but it generally does the job.
I came to know that eclipse can be used for other languages as well. But will it give the same comfort level as using java? Is there anybody who has used eclipse for other languages?
I've used Eclipse for both C/C++, Ruby, Erlang, and a few others. None of these are as tightly integrated with Eclipse as Java is, but CDT (C/C++) gives Visual Studio a good run for its money. I usually use Emacs for the other ones.
Yes, you can use Eclipse for many languages other than Java. I personally use Eclipse to code in C++, Perl, PHP, and do JavaScript as well inside of it. While it also supports plugins for connecting and executing queries against databases, I tend to prefer other options there such as Toad or Oracle SQL Developer. There are numerous other plugins to support many other languages that you can find either through the Update Manager or a simple Google search, many of which are excellent.
As a side note, if you're not using Mylyn, you're missing out.
Eclipse is used as a base for other language and tool:
for example As3 with FlashBuilder; PHP, Javascript with Aptana studio, C,Python,... with other plugins, etc...
You can found here for example some plugins for other languages.
I've used it for Javascript (jQuery): compile-time checks are a godsend to the barren lands of javascript.
For Java developement I feel most comfortable using Eclipse.
I tried using Eclipse for coding with Python. There is PyDev, an Eclipse plugin that can be used to work with the Python code in Eclipse. Though PyDev provides features like Code Completion, Syntax highlighting etc, I felt comfortable to use editors like gvim or emacs rather than Eclipse
for working with Python code. YMMV
Yes, Eclipse supports many other languages.
But you knew that already when you saw http://www.eclipse.org/downloads/
So, I guess that you are asking how well it supports them...
It is possible to have Eclipse without Java. Imagine taking that and then adding Java support. Compare that with CDT for C++ and - in my experience - they are pretty much the same.
Yes, Eclipse is slanted at Java, and I doubt that anyone will deny that, but at the same time it tries to be fair and generic and pretty much achieves it. Any few % less other language support doesn't matter when you realize that no other IDE compares.
Bottom line, whatever your language, you will be hard pushed to beat Eclipse.
And that's before I get started on the myriad plugins ...
Not only programming, debugging with Eclipse is sweet. Beside Java, the other languages I mostly work on Eclipse are PHP and Python.
While I was working on the Eclipse Web Tools Platform (WTP) project we often said that the Java Development Tools (JDT) were the model that we referenced for features for Web related languages. I think JDT has set the bar and many other projects that implement language specific tooling try to reach the JDT bar. I don't know that any have or that copying everything about JDT is the point but I do think the Java tools are exemplary development tools.
Is it possible to create Eclipse plugins/program Eclipse RCP apps without Java? (preferably in Jython)
This will be possible in the next Eclipse major release e4:
One of the goals of e4 is to provide support for writing plugins in other languages.
The quote is from http://wiki.eclipse.org/E4/JavaScript which summarizes the current state of using javascript to implement eclipse plug-ins in e4.
This issue in eclipse's bugzilla issue #227058 also has some discussion on that, but I believe it is outdated.
I am currently not aware of activity regarding other languages.
No. An Eclipse plugin is an OSGi bundle, and that requires interacting with a variety of things that can't implemented in Jython as far as I can see.
If you want to avoid Java, you can look at other things that target the JVM, but you will have to figure if you can produce and consume the specific items needed to call the necessary things and be called in the necessary ways.
OSGi bundles may be written in other JVM languages like Scala. Eclipse plug-ins, as of now, does not support any language other than Java. The Eclipse Plug-in Development Environment heavily makes use of JDT which ties it to Java. However there are some plans I heard that plug-ins might be supported in other languages. But I don't see that coming in near future.
You can write your main code in Jython and use Java interfaces to call then from Java. Take a look at this for details. Also, I am writing a utility library (github.com/abhin4v/jywrapper) to do the same. It has very little documentation right now, but you can look at the examples provided.
