I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them.
I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before.
My question is:
Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?
Use the Microsoft® Windows® Script Control because it is easy to integrate into existing VB6 applications. The control supports VBScript, JScript, or any other "Active Script" implementation.
I have used the Windows Script Control in four projects and it works extremely well. Very easy to integrate. I wish Microsoft would have given us a replacement in .NET, and made it as easy to use. (I understand the control is not needed in .NET, but having the ability to simply create an object that handles everything is nice.)
Windows Script Control
The Microsoft® Windows® Script Control
is an ActiveX® control that provides
developers with an easy way to make
their applications scriptable. This,
in turn, enables users to extend
application functionality through
scripts, much as they do with macros
today.

Unless you're doing it for your own instruction, you may want to try using Lua: VB6 - Lua Integration
If you're willing to use VBScript rather than VB6 you might be able to just use the MSScriptControl to run the commands rather than creating your own. Here's an article discussing using it from a .Net app, though it's an ActiveX control so should give you quite a bit of flexibility.
The control can be downloaded from here.
I've actually seen some quite reasonable implementations of compilers/interpreters in VB6[1] - It's not the language I would choose (few functional features, insufficent static type system), but with experience, you can outweigh these drawbacks and be quite productive - So why not.
You can use the GOLD parser generator that supports VB6 as a start.
[1]: Somewhere on PSC or in this download repository I think ...
Note that there is the MSScriptControl too.
There also appears to be an additonal alternative for VB6:
SadScript is an variant of VB6 most prominently used for VB6 as an scripting engine in MMORPGS .
See here for more : What is sadscript? Can I use it in vb.net? Why hasn't anyone I have asked heard of it?
As every programmer knows tools are important and there is no tool more important for a developer than the IDE you use to code. In the last few years the IDE-s fall into standards and it is not common to see innovation in this area. What IDE-s you can recommend as innovative and what new ideas and paradigms they introduced?
This is by far the coolest set of coding tools yet!
http://vimeo.com/36579366
I haven't used this but saw the demo video yesterday. The IDE is called code bubbles and has a unique way of showing and grouping related code together.
That said I find the intellitrace feature in Visual Studio 2010 quite innovative.
Palm's Project Ares: http://ares.palm.com/Ares/about.html
It's the IDE for the Palm webOS phones, that runs entirely as a web app. You build and run your app inside the browser, and when you're done, you deploy straight to the cloud.
I'd put my bet on Meta Programming System by Jetbrains. The concept is not new but it's the first time it has been implemented on such a huge scale with great IDE support. You create a DSL first, then write programs in that DSL and finally generate code in a target language.
I'll go for Scratch, though I wouldn't want to write a banking system using it :-)
Some cool videos of structured editor prototype that will let you directly code the AST.
This is a prototype only and I have no idea if it is still being developed.
One interesting IDE I have seen only on video is Code Bubbles. It opens code snippets as a graph of visual "bubbles". It is really interesting and definitely something I want to try.
I'm tired of Dreamweaver overwriting wrong files on the server,
so I'm looking for an alternative.
I want color-coding and possibility to open/save and edit files direct from the server, so I don't need to save files on my desktop first.
I'm using Windows.
Every web developer should be hand-writing their mark-up - all forms of automated abstraction inhibit your understanding and awareness of the code and create maintenance problems for the future. I'm quite a zealot about this, you may be able to tell.
On that basis, I can heartily recommend Editplus: has code colouring, FTP and a huge amount of feature-sugar from line duplication to macros.
Notepad++ extended with some plugins is a really handy replacement. Though I can't call it IDE, it does virtually everything a developer need. In my case (a lot of repetitive code) Texter (a small app working in background) makes notepadd++ even more handy. So, my suggestion is: Notepad++ and Texter.
I switched to notepad++ when I had the same kind of problems with DreamWeaver. I tried some other programs too, but they were too complicated for my needs.
If all you need is color-coding and ftp-support, notepad++ is a good choice.
Visual Web Developer Express, which is the lightweight version of Visual Studio.

If you're using a Mac you should take a look at Coda
Well personally I use Programmer's Notepad but it doesn't support the facility to upload files to the server. You could get Notepad++ and this FTP plugin. I haven't tried Notepad++ but I'm sure that it isn't WYSIWYG.
Perhaps KompoZer? It has all the features you've asked for, and there's a Windows version (as well as Mac and Linux).
Dreamweaver... Not my cup of tea, because it lacks good support for modern web programming with Javascript or PHP.
For primary design, I use WeBuilder from Blumentals. Its also a good and not expensive PHP and Javascript IDE with debugging support and also has good CSS support with a built-in CSS editor.
I'm not a big fan of text editors like Notepad++ as an IDE replacement, because you often need a lot of additional plug-ins to have similar features like a IDE. But for some files or quick editing nothing can beat such editors (I like Notepad++ the most on Windows).
So for Windows I would prefer WeBuilder for all things (design & programming).
You use only Windows? For Linux there are other alternatives too ;)
When I searched an alternative for the Dreamweaver for PHP, I found some IDEs and one among them is Netbeans. Soon it became my favorite for my object oriented coding.
Here is the download page.
This has support for Zend and Symphony frameworks.
They also support File uploading.
When developping in PHP, I generally use Eclipse PDT.
If you are more oriented towards HTML/CSS/Javascript, you might be interested by Aptana, which is based on Eclipse too... Which means it can use lots of plugins, including some to work directly on a server, I suppose (see TM/RSE, for instance).
Note than Aptana can also be installed into an existing Eclipse installation, as a plugin.
Oh, also, I almost forgot : Eclipse is free, and there are both a free and a commercial version of Aptana.
(One bad thing about Eclipse being it requires a quite powerful computer -- at least 2 cores and 2 GB of RAM, if you want to use any other application at the same time...)
E Text Editor, a Textmate clone for Windows, claims to have FTP Support. But i haven't used this feature before.
I want color-coding and possibility to open/save and edit files direct from the server, so I don't need to save files on my desktop first.
The Zeus editor can highlight and fold HTML files, it integrates with HTML Tidy and can seamless edit files from the server via ftp/sftp.
It also has support for a host of other languages (i.e C/C++, C#, Java, Javascript, PHP, etc etc)
Does anyone know of an alternative IDE for Sybase Powerbuilder? It feels pretty clunky, after working with VS2008 and Eclipse.
If not, has anyone successfully worked with this language outside the IDE? I'm not against using a simple text editor, but I find edit-import-regenerate-test-export-edit is clunkier than simply using the Powerbuilder editor.
To date, the only tools I have had any success with are:
PowerGen, for builds (with NUnit and CruiseControl.NET)
ConTEXT, which has syntax highlighting for Powerbuilder
PBL Peeper, which has some interesting features not present in the IDE
EDIT: I added a bounty to draw some wider attention to the question. It would be a very nice thing to have, if it exists.
EDIT: Well that was disappointing. The bounty apparently did not cause even 1 new person to look at the question.
None that I'm aware of, although you could probably use a source control tool, edit in your source control repository, and Get Latest Version from the PB IDE to shorten your text editor cycle. Be warned that there are hacks required to edit anything over 128 ASCII. (My guess is that this is to allow everything Unicode to be source controlled in the most restrictive source control tools.)
As Paul said, PB12 is coming with based on the Visual Studio shell, and will include things like collapsible code blocks, Intellisense, etc.... However, for PB12, this will only be used for WPF targets and a few .NET-type targets (like assemblies), last I heard. Win32 targets will continue to use the "classic" IDE.
Good luck,
Terry.
P.S. Thanks for the PBL Peeper compliment.
The PowerBuilder IDE is clunky, but I don't think developing completely outside the PowerBuilder IDE is a good idea. I think there are just too many dependencies right now.
However, the IDE for PowerBuilder 12 will be built using Microsoft's Visual Studio Isolated Shell so it ought to be much better when that is released. Also, I believe they'll be doing away with the PBL format which ought to make source control much easier to work with.
Certainly something to watch.
What I do is right-click the object and edit source. Then I copy the text and paste it into Notepad++ to edit. I copy and paste back to PowerBuilder, then I can save and see any errors. I've got a fairly decent User Defined Language for PowerScript if anyone's interested.
Added:
Please be aware that I've seen the PB Source editor corrupt DataWindows. They were all large DataWindows. To be safe always export DataWindows to edit.
One tool that will most probably make your PB experience way better is Visual Expert, which provides a good source browser. Such a tool should have been integrated into the PB IDE a long time ago, IMHO. Only problem is that it's not free, as opposed to the other tools you mention.
Regarding using external source editors, you can probably take advantage of OrcaScript, which is a scripting language that lets you perform actions such as export and import of PB objects from outside of the IDE. It will require some effort, but you can setup a basic dev env using batch files with ORCA scripts and some additional external tools. However, this setup will lack any visual editing capabilities, which means no (feasible) GUI or DW work. If you're mostly into NVOs, it could work. But then if that's the case, why use PB in the first place?...
I too have heard PB12's use of VS will be limited to some .NET stuff, which will probably benefit only a very small portion of the PB programmers community. I'm afraid the rest of us are stuck with the awful IDE for years to come.
Other than exporting the source and editing it I don't know of another IDE for PB. One problem you may have is that the exported source contains a lot of syntax that is not documented in the manuals. The PB IDE generates this code but there is no support for creating it by hand. I think you are stuck with the PB IDE
In my modest five Years of experiences starting with Powerbuilder 5/6, now using PB 10, I tempt to :
build my own browser from the classdefinition object based on Powerbuilder
tried to use autohotkey in order to open datawindows comfortable (we have several thousands in the project and i am two-finger-driven)
truly investigated in the idea using an external editor/IDE suppoted by an autohotkey script which is undermined by sybase allowing only mouse-click-usage of PB
using Visual Expert which is neither a truly integration in the IDE, nor is really worth in analyzing datwindow/powerscript interaction
ending by build hopes on PB12 Visual Studio, which lacks - depending on compatibility issues - ...
... i came to the conclusion that there will be no chance in improving Powerbuilder to an state-of-the-art language
In my philosophy - I obtained during those years - I distinguish between two types of OOP-oriented languages:
the one that award using object-orientation like C#, Python, Ruby (C++) etc. and very much the Java-Eclipse/Netbeans-Universe does
the other one that punish using object-orientation like Powerbuilder and the old Visual Basic, for example (which is causative the OOP-Idea comes afterwards and is "plugged in").
Especially the demand that all object should always be compiled (regenerated) and that you could't work with ancestors and descandants concurrently makes it painful to use real OOP.
...In memory of the good old Unix(Solaris)/C++ days...
I was researching a replacement solution that would be similar to PowerBuilder and I came across two that caught my eye.
The first was 'React Studio' https://reactstudio.com/ which I found via Alternativeto.net .
And the second was from an ad at the top of some Google searches but it was similar enough and looked good enough at first glance for me to want to take a closer look at it, and it's called 'Servoy' https://servoy.com/ .
Still researching but I currently have React Studio at the top of our list.
The TextPad editor has a syntax definition file for PowerBuilder 6.x contributed by anr#aon.at that I downloaded for free and customized several years ago. It works fine for later versions (including 8), doing keyword color highlighting on PowerScript srx files. Editing large source files in PB could get it to crash so it's usually safer, faster and more convenient to export to srx file, edit outside the IDE then re-import.
I'm looking for a way to automate a Siebel Retail 8.1 GUI (High Interactivity) for functional tests.
The only option I found so far is using QTP from HP, which is quite expensive.
Do you know any alternatives, or do you have any experiences with QTP?
QTP is a great all-purpose test automation tool. I do not know much about Siebel Retail 8.1 GUI - is it web-based or thick client? If web-based, there are a ton of alternatives, including open source. If it's a thick client, you are limited in your choices. Vendor alternatives to QTP are IBM Rational Functional Tester, Compuware TestPartner, Borland SilkTest.

Oracle ATS is the official tool to automate Siebel GUI.
There are 2 different Siebel GUI, one is the old HI/SI, which is activeX and need IE to view.
another one is called OpenUI, which is pure web.
Oracle ATS both support them, following video at Oracle show how to test Siebel.
the first one is created by me. and the last two for load testing Siebel.

I know it's a late reply - but please don't put too much faith in QTP to test Siebel. Experience of myself and colleagues in the Siebel development community (yes, there is one :) have found considerable problems with the practicalities of using QTP to test Siebel.
