I've been using smalltalk for a while now and I love the language and the concept. What I just hate is the System browser. This tool doesn't even resemble a modern IDE. How am I supposed to code without tabs, outlines and handy shortcuts? I often find myself implementing a selector and noticing that it would be nice to isolate a piece of code in a separate (private) selector, just for readability shake, but I don't. Because it takes like 5 mouse clicks and I have to navigate away from the selector I am working at, and navigate back to it. Oh wait, I can't! Because it has syntax errors, because I haven't finished it yet! Kills me. And I don't have a 24 inch display to open 3 browsers.
Sorry for a little rant. My question is, is there a real IDE (Eclipse, Net.Beans, VS) for smalltalk? Maybe for some commercial version of smalltalk?
You might want to check out tODE. It's at a very early stage, but it is an attempt to provide a Smalltalk IDE in the web-browser and is a break from the traditional Smalltalk IDE. With that said, I don't think you'd want to start using tODE right away, but you can keep an eye on it as it evolves.

Pharo is trying to have the Nautilus Browser ready for Pharo
1.4. I suspect there will be a flood of awesome new tools as the system stabilizes over the next few releases.
There's the Glamorous Inspector.
Spoon has been mounted as a WebDAV filesystem, so you can use whatever tool you like. Spoon is not another Smalltalk, but a testbed for revolutionary Smalltalk technology, which can be incorporated into any other Smalltalk (it's currently on top of Squeak)
There is the Tiling Window Manager to help you organize
Since Squeak and Pharo are live, dynamic, open systems powered only by volunteers, anyone sufficiently motivated can create the next generation of tools ;-)
p.s. I feel your pain. The 20-browsers-open thing is a drag. Let's invent the future!
Historically, the real "IDE" is the Smalltalk one, and one could claim that the others are just an adaptation to the limits of traditional textual programming languages (not rethorical, just check out the evolution of typical development environment UIs and how they are adding features that exists in Smalltalk from the very beggining, like the senders and references in VS).
Just a side note: actually more than 2000 open-source projects in the SqueakSource repository were coded without tabs, outlines and shortcuts (I think still in Squeak you can cross reference any text selecting and pressing with Alt-6). I can't tell you how sad I feel when I must to go back to file based developement, still don't understand why most developers love to sweep text, mess with line numbers and page up-down files in directories. The good news for you, is that you have many options:
There is an alternative browser called BobsBrowser (works in Pharo 1.3) which lets you browse
Class hierarchy windows exploring each class
System Category window
Unsaved edits
Recent classes
Recent methods
Method categories for instances and classes
Unsent methods
Driller relating every structural information
etc.
The advantage over the Whisker browser is that the hierarchical lists are attached to a window while in BobsBrowser you can detach them.
It all depends of the different activities you're performing when you're developing. With some experience in Smalltalk you'll find that you prefer some browser for exploratory insights and others for refactorings, etc. BobsBrowser for example is good for knowledge organization or custom navigation of Smalltalk classes and categories, the hierarchies you can see are the organizations from the Smalltalk reflective meta-architecture at any level (classes, senders, implementors), and they are expandable/collapsable (in the classic system browsers you can only expand the system categories and subcategories).
The instance variables were shown historically in the Smalltalk/V flavors, and there is an old goodie (from Squeak 2.7 IIRC) to enable it back again but almost nobody today maintains the classic System Browser in Squeak/Pharo. Adding that feature to OmniBrowser would be more complicated though because is a browser framework (as every serious framework, it took some time to learn it for the first time), although the effort of the Squeak/Pharo community is absolutely incredible, still the Smalltalk community needs more developers.
You have also a commercial Smalltalk which isn't public (downloadable) yet but includes IDE-like features of traditional programming environments
And I don't have a 24 inch display to open 3 browsers.
You could give the Whisker Browser a try. It lays out the methods side-by-side so that you don't have to position all these windows manually.
I played with it a few years ago but I'm not sure what state it's in right now.
I don't know how mature it is, but the Etoile project has an IDE called CodeMonkey for writing Smalltalk applications. It's not specifically for Squeak, and instead uses their own smalltalk implementation, but it may be worth looking into. Unfortunately, it's only available in their SVN repository, so it's a pain to compile and install.
Where can I find the code for creating an online rebol console like the one here ?
http://tryrebol.esperconsultancy.nl/
Update: for the sandbox system on the server, can't Rebol manage it itself with some security wrapper and its security options ?
As for console itself, I don't know Ruby so I don't want to use TryRuby and why would I need it ? Can't I mimic Rebol console itself by "remoting" it somehow ? Why RT or Esper Consultancy can't make an opensource version ? There's no value in keeping it closed source. Rebol needs to prove it's more open than in the past.
In my opinion, you should aim higher with something like the already open-sourced Try Ruby. You'd type in expressions and it would guide you. Their showcase site is at tryruby.org and is fairly slick.
I modified TryRuby to work with Rebol and it wound up looking like this:
But I'm not going to run it on my server because I didn't want to belabor the necessary sandboxing/etc. or protections against someone running an infinite loop. I can give you what I've got so far if you want it.
I started a tutorial script here that no one seemed interested in helping me with, so I wandered off to other tasks:
http://www.rebol.net/wiki/Interactive_tutorial_script
I'm not sure what exactly you want. You mention you want a remote REBOL shell instead of a tutoring setup, but that's what the Try REBOL site is. There are several reasons it's not open source:
It's in heavy development. I'm currently changing the code regularly.
So it's not in a release state. Preparing it for release, documenting and publishing it would take a lot of extra work, as with most projects.
It's written in my CMS that's also in heavy development. Even if the Try REBOL site were open source, it wouldn't run. The CMS is not planned to be open sourced soon.
It's not meant as a generic REBOL remoting tool, but as a one-off demo site. If that site is running, what's the use of more of them?
As others have answered, there are many generic solutions for remoting that you could use. Also, most parts of the Try REBOL site are readily available as open source:
Syllable Server, produced and published by us.
The Cheyenne web server.
The HTML source of the web client can be viewed, including my simple JavaScript command service bus.
Syllable Server is an essential part of the site, as the sandboxing is not done with REBOL facilities (except some extra limits in the R3 backend), but with standard Linux facilities.
A truly air tight (do I mean silica tight?) sandbox is close to impossible with R2.
R3 (still in alpha) is looking a lot more promising. The deep technical discussions in flight right now (see Cure code and AltME/REBOL3 Proposals regarding unwinds and protect and even occasionally mentioning sandboxes should lead to an excellent sandbox capability.
Right now, the big advance R3 has that makes Kaj's tryREBOL possible is R3's secure policy settings which make it possible (with some careful wrapper code) to construct an alpha/demo sandbox.
To answer your precise question("where can I find code...", you could try asking Kaj for his :)
I'm new to StackOverflow. I'm not sure if this is going to end up as a reply to your comment, or as a new answer.
The somewhat common idea that any project can be open sourced and contributed to by others is a naive view. In the case of my Try REBOL site, it makes no sense. It's not just in heavy development; it's written in a CMS that's also in heavy development. Basically noone could contribute to it at this point, because I'm the only one who knows my CMS. Or in any case its newest features, which I develop by developing Try REBOL, and other example sites. So developing Try REBOL means developing the CMS at the same time, and by definition, I'm the only one who can do that.
More generally, my projects are bleeding edge, innovative technology with a strong vision. The vision is mine, and to teach it to others, I have to build it to show how I intended it to work. So there's a catch 22: to enable others to contribute, I have to finish my projects first, because people typically don't understand them until I show them how they work.
There certainly are other projects where mass contribution makes more sense. Still, only the top projects get the contributors. We found that out the hard way. We created Syllable Desktop and Syllable Server with surrounding infrastructure for contributions. These are fairly classic, well understood operating systems that many people could work on in parallel. However, despite years of begging, we get very few contributions.
So, if you feel a burning need to contribute to our projects, please pick one of the many tasks in Syllable to execute. :-)

I am just starting at a job in which I will be using a lot of ColdFusion. What is the best IDE/Editor to use?
I'd like to provide my personal reasoning behind why you might choose any of these editors (at least the ones I'm familiar with). Just saying "use this, use that" is not at all helpful. To large degree, the question is wrong. There's rarely a "best IDE" for a language; rather, there are multiple environments, each suiting particular needs. Here goes:
1) Dreamweaver
Why you would use it: its history as a designer tool makes it much easier for "non-coder" types to start cranking out websites. If you're a solo developer building a lot of "Tom's Corner Store" type of sites, even if they require some CF Coding (mailing list, subscribers, current specials, light content management, etc), its design tools, "template" features, and ease-of-deployment (ftp) make it an attractive choice. It has good-enough code coloring and code completion for the built-in CF tags and functions. It can interrogate user-defined functions in the same page. It has excellent CSS support. You can find a wealth of extensions, too. It's pretty stable and, in my experience, hasn't been very "crashy". It will do a fair amount of code generation for you as well (whether that code is "good" is debatable). All in all Dreamweaver is incredible software for web site designers.
Why you wouldn't use it: It is not free, and it is certainly not a "coder's editor". While it provides for extensions, they're typically interface-focused (javascript validation, etc), unlike say Eclipse plugins, which can run the gamut. For large projects, it simply does not have the code navigation features that many coders come to expect. It's web-focused. So if you're a polyglot, or even just like to dabble in compiled languages (java, etc), then you'll need to keep another editor on hand for those tasks.... you won't be able to do it all in one place. ColdFusion unit testing support is nonexistent in Dreamweaver. There is no step debugging for ColdFusion.
2) CFEclipse plugged into Eclipse.
Why you'd use it: CFEclipse is going on 6 years old now and has matured significantly. It's been quite stable for the last few years and most crashiness has been due to Eclipse itself and not CFEclipse (which was not true in the early days). Recently CFEclipse has seen an infusion of fresh blood and features are being added to make coding in it even more productive. It contains a wealth of keyboard shortcuts, many of the toolbar features people love from ColdFusion Studio days, and Eclipse's in-built code navigation features (namely, Ctrl-Shift-R for finding files quickly).
It has content assist for native CF Tags and functions, and some support for in-page variables, though that's never worked all that well. It does not support in-page functions, nor does it provide native true component insight (i.e. insight into components that you write and use in other code). It will support component insight to some extent with Dictionaries, but even then, it requires a lot of work on the part of the dictionary creator. Most people find dictionaries too much work to maintain, in my experience.
The lastest version of CFEclipse contains the best CFML formatting you'll find.
For me, "method explorer" and "Snip Tree View" -- particularly keyboard shortcuts for inserting snippets -- have been big productivity boosters.
If you work with ColdSpring, ModelGlue, Mach-II, ColdBox, and other frameworks with xml configuration files, CFEclipse's Framework Explorer is brilliant.
Because it's a plugin to Eclipse, you can do everything else you'd want to do in Eclipse. You wanna code java? You can. You want webservice support? you got that. You want to do step debugging, you can do so with the free Adobe-provided extensions for Eclipse.
The large plugin ecosystem is one of the most attractive features of Eclipse, and you shouldn't discount this when deciding on an editor. For example, I would not want to work without Mylyn, which integrates with issue tracking and in my experience has transformed the way I work, much for the better.
Eclipse's version control system support is excellent as well. Subversion is well supported; there's a VSS plugin; and recently a git plugin (if not two) has been accepted into the Eclipse foundation so we'll see native git support very soon (you can get it now with a plugin).
Eclipse's ANT support is excellent.
You can easily plug the MXUnit Eclipse plugin into Eclipse for unit testing your CFML (full disclosure: I contribute to MXUnit).
Finally, I have full confidence that the folks working on CFEclipse -- Denny, Mark, Jim, Peter, et al. -- will continue to work toward keeping CFEclipse as the best open source CFML IDE available. These are some of the brightest minds in the ColdFusion community and are passionate about their mission. If you choose to use CFEclipse, you are not choosing to use an IDE that will be supplanted by ColdFusion Builder. This project is in good hands.
Why you wouldn't use it: it's a code IDE, not a design tool like Dreamweaver. It's not perfect... code assist can be too aggressive in its suggestions. Eclipse itself, especially when you pile it up with all kinds of plugins, can get unstable on lesser machines. Finally, people who don't like the "Project" view of the world often have complaints about it because they're used to working directly with the file system view of the world. Its deployment support is nowhere near as simple as Dreamweaver, though you can find plugins that get close.
3) ColdFusion Builder
Why you'd use it: all of what I said previously about Eclipse itself applies to CFBuilder when used as a plugin to Eclipse. I cannot speak to the Standalone version because as of this writing, it still doesn't support plugins very well. This will most surely be fixed by the time it is released, but I don't want to speculate on what the Standalone may or may not do.
One of CFBuilder's big draws is "Extensions". These are a way to plug in CFML code into your editor. It's hard to describe, so I'd suggest googling for "ColdFusion Builder Extensions", and you'll most likely be amazed. Adobe's Terry Ryan has created "Apptacular" for scaffolding applications from a database, and Brian Rinaldi has a series of posts on building CFBuilder extensions. These are huge and will prove themselves to be a developer's best friend after CFBuilder is released.
CFBuilder's deployment support is, in my opinion, on par with if not superior to Dreamweaver's.
CFBuilder does not require an additional plugin to do step debugging. Just hit the debug button and off you go.
CFBuilder contains true component insight, meaning that it can introspect components you write and provide ctrl-space content assist. It can be wonky, however, and does require some configuration. But please remember that as of now, CFBuilder is still in beta. My best guess is that it'll be at least a few versions until all the kinks are worked out of this feature. Still, it's a big productivity and learning booster to get content assist on your own components.
CFBuilder provides a "Servers" view for stopping/starting your CF Server. It's built on Aptana and so contains the Aptana "tail log" view, which is great for watching log files. Just like CFEclipse, it has a Snip Tree View.
The CFBuilder "vision" is led by Adobe's Adam Lehman. He's passionate about CF and is a force of nature. I have great hopes for CFBuilder because of Adam's leadership.
Why you wouldn't use it:
For one, it won't be free. Noone outside Adobe knows yet how much it will cost, however. "Extensions" and the deployment features alone may be worth the price. Time will tell.
Because it's an Adobe product, I think it's reasonable to assume that releases will come as frequently as most Adobe products, which means... not very often. While CFEclipse deploys rather frequently lately -- and makes available a "nightly" site for the brave -- CFBuilder will most likely not do such daring-do. CFEclipse can afford to make potentially unstable builds available to the public, while it is perhaps not in Adobe's best interests to do so with CFBuilder.
Finally, it's still in Beta and might not be released for some time. If you get it now and start using it, remember that. In my experience, debugging is wonky, content assist sometimes works, sometimes doesn't, and a lot of people have experience crashiness. It's free beta software... you're getting what you pay for. But know that the more you work with this beta release, and particularly if you provide feedback via the public bug database, the better off all of us will be if it provides a best of breed editor for CFML.
Personally:
At home, when I do "designer" work, I use Dreamweaver when I feel that its Templates will help me build a site as quickly as possible. For existing side projects which require maintenance coding and easy deployments, I use ColdFusion builder.
At work, where I do almost no design work, CFEclipse has been my IDE since 2006. I've begun using ColdFusion builder a lot, though currently I split my time between CFBuilder and CFEclipse. One reason is that as of this writing, CFEclipse is more stable (i.e. it doesn't crash and I don't lose work). I fully expect stability problems to be mitigated by the time CFBuilder costs money.
Both CFBuilder and CFEclipse have public bug databases. CFEclipse has a well-attended public mailing list, and if you have questions, you'll get answers quickly. I cannot yet speak to the speed with which CFBuilder questions are answered.
Finally, for "coders", it's my experience that once you invest the time in learning the tools and shortcuts, Eclipse provides superior productivity compared with designer tools like Dreamweaver. For cranking out a designed site, a designer tool like Dreamweaver confers significant advantages.
The answer to the best ColdFusion IDE isn't an answer, but a question: "What are you trying to do with ColdFusion?" The answer to that question will lead you to an IDE that suits your needs for a particular project. Different circumstances or projects may lead you to a different tool which better suits your needs.
Notepad++ with CF syntax highlighting.
For free: Eclipse with CFEclipes plugin
For cost: If you're a developer, use Coldfusion Builder, if you're a front end designer Dreamweaver edits Coldfusion pretty well. I use it quite often.
I have heavily used Dreamweaver, CFeclipse with eclipse and now Coldfusion Builder. What I found is this:
1) Dreamweaver is only good for the few times you have to do some wysiwyg wizardry. The newer versions do have SVN integration so you might be able to get away with using it. I did use it for a few years on windows.
2) CFEclipse + Eclipse - Generally the standard of what' sbeen used for a while. Runs well, once you add in the Adobe dictionary files and subclipse, you have a good environment
3) Coldfusion Builder - This is Adobe's version of CFeclipse. It's still pretty new and getting to later beta. I switched to it about 6 months ago and haven't looked back. It's got a lot of wizards, including the ability to write your own plugins in CFML that will run right inside CFbuilder. It's free right now on beta but will likely be pretty cheap like the first flex builder that came out.
My Choice: Coldfusion Builder. It doesn't mean the others aren't capable, but you'll spend the least amoutn of time getting setup and maintaining your plugins, etc.
Since I had paid for and used Dreamweaver for a lot of years (Eclipse was generally sluggish sometimes on PCs' a while back until the excess of ram + cpu today), spending to have an adobe maintained copy of eclipse is okay with me. The wizards available in CFbuilder, especially for flex are excellent.
Hope that helps, good luck and share what you ended up picking and why!
For anyone who might stumble here from Google, you should also take a look at Sublime Text coupled with the ColdFusion package.
If you are familiar with Eclipse I would recommend Eclipse with coldfusion plugin.
http://www.cfeclipse.org/
Some use Eclipse, some use ColdFusion Builder, some use emacs or TextMate or vim. I use vim.
It doesn't take much time to try out an IDE or editor. Give them all a shot and stick with the one you like most.
The best IDE is ColdFusion Builder. It allows RDS, In Line Debugging, Extensions (written in ColdFusion!), Code Generation, Refactoring, supports JavaScript, CSS and HTML and so much more. It is currently in beta and should be released in production sometime this year.
CFEclipse is a great IDE for CFML and is the right choice if you are writing CFML for the open source engines. It is free and like most open-source free products it can do almost anything Builder can do if you invest the time to install the additional plugins (like Aptana) and tweak your setup just right.
I use both. At work, we use Builder. At home, I use CFEclipse.
Welcome to the CFML community!
Notepad++. Light and easy to use.
I'll vote for jEdit. While it doesn't offer great ColdFusion support beyond syntax highlighting, and therefore probably isn't great for learning ColdFusion, its flexibility in working with other languages (which seems to happen fairly often while working on the web), powerful macros, plug-in support, proper text wrapping, and loads of other features, make it the editor to which I always end up returning after trying out the "next best thing".
CFEclipse appears to be the most popular. Adobe has a beta of ColdFusion Builder (also based on Eclipse) but when I tried it a few months ago it was still buggy.
Personally I use TextMate (OS X) a pretty bare bones text editor.
I have used textpad, for 6 years, still a solid app, provides syntax coloring/highlighting, regular expressions support. Can easily search inside any file, through tons of folders/subfolders.
Just a fast loading, easy to use, tool.
Also has macros, and macro programming...
http://www.texptad.com
I'd like to throw E TextEditor for the Windows users in here as well. Its similar to sublime but it does have its advantages. E is more or less Textmate for windows and will allow you to run the cftextmate bundles. In addition to being lightweight and extremely fast you get the huge Textmate community developing bundles, color schemes, and other community driven content.
Some of the highlights of E is that it will allow you to open a directory and treat it directory as a project. Hitting Shift-Ctrl T will allow you to browse all the files in your project in a flattened hierarchy which allows you to find files extremely fast.
I'm looking at rewriting an eMbedded Visual Basic app I wrote years ago. I'm unsatisified with it because of various problems clients keep having with it now and then over the years, mostly along the lines of the app not loading anymore because a required dll/activex control has gone missing! This is so frustrating and naturally difficult to debug when a client is using it far away. In alot of cases reinstalling the app doesn't fix the problem.
My preference would be to rewrite it in C# since I'm comfortable with C# and DotNet, but I'm also open to other platforms like blackberry or iTouch/iPhone so long as the platform can support maps and GPS. I'd start rewriting it in C# now but I can't be sure that I won't have the same problems in .net.
Has anyone else had similar problems with eVB apps which have gone away/persisted when moving to CF DotNet? Or would you suggest a different platform again?
Edit: Note that I wish to move away from eVB anyway, but if I move to CF DotNet I want to make sure I won't have the same missing dll/control problems.
I recommend .NET CF strongly, especially if you already know C# and .NET. Mono has been ported to the iPhone, so it is possible to write apps that will run on Windows Mobile and the iPhone. No Mono for Blackberry (yet, if ever), so that's a definite limitation. I personally can't stand Blackberries (I have both a Blackberry and a WM smartphone and the Blackberry makes me want to hang myself), but they do have a huge user base.
You should have migrated away from eVB years ago, but that's water under the bridge. If you want to continue targeting Windows CE/ Windows Mobile I'd recommend going to the CF - language is irrelevant, use what you're comfortable with.
There's no way to guarantee that whatever your "missing DLL" problem is won't happen again, since we have no idea what DLL went missing. If it was a 3rd party control, then you're at the mercy of the market. If the provider survives, it's likely their control will.
If you want to target iPhone/Blackberry then Java is more likely to be your language of choice - the tools I'm not as familiar with. Eclipse for Blackberry - iPhone may have their own tool.
As for Silverlight, you might look at it, but so far it's just way too slow to be a viable platform, at least on any WinMo device I've ever seen. We've delevered many, many CF apps for all sorts of verticals and have never had any usability problems (though we've been doing it a long time and know every limitation and what we should and should not be trying).
I suggest you take it one step further and look at Silverlight. One of the premises is that it's a more long-term-stable, portable, lightweight download and install, and it hasn't gotten krufty yet.
I think it has the potential to be the next VB for embedded. One of the difficulties with CF is that I've found it to be an insufficient subset of the real thing.
Another option is NS Basic/CE. It's highly compatible with eVB, so you will be able to keep most if not all of your code. The product has been continually updated so it runs on current devices.
The installer that NS Basic/CE creates includes all the dll files your program requires, so they will be included on installation.
I am planning to design an application XUL & XPCOM for proprietary system. So i have decided to use C/C++ but how can I start the development as a beginner in this field
I cannot find a good guide to start around. It will be good if you can give some links
and books. I also would like to know how to prevent the user from modifying the code specially in the view part because the logic can be done in XPCOM.
XUL explorer is a tool that lets you drag and drop XUL. It's good for mocking up an interface or starting to learn about the various elements you can use.
xulrunner is Mozilla's binary that allows you to run XUL/XPCOM/javascript applications.
The Mozilla Developer Center is your friend.
If you use IRC, check out #xulrunner on irc.mozilla.org . They are fairly tolerant of some questions from beginners.
I don't think there's going to be away around allowing the user to see (or potentially modify) the actually XUL interface. There are some paths for trying to secure JavaScript in some way (some surface level, like obscuring, minifying, but then some possible secure loading methods). XPCOM can be written in C++ or JavaScript, to name a few, if you put more of your code in XPCOM it should be more secure, I think.
A fun start for seeing what you can do in XUL is to check out the XUL Periodic Table.
Preventing the user from modifying your code is futile, as they will always be able to do this.
You could of course ship a modified build of xulrunner (containing some required XPCOM as well) which only loads jars signed by some key, but they could trivially hack around that by modifying the binary or the image in memory.
So don't bother trying to stop people modifying your code - you can't - unless you're on a trusted platform such as a games console - and even then it's not guaranteed.
This helped me to create my first XPCOM.
