I have more of a general question. In my experience there was no other text editor which did exactly what I needed as Atom, with its' plugins of Hydrogen, VIM, and many other useful packages and rich community of developers.
After the GitHub graciously shut down the atom.io and basically killed Atom altogether (to create some incentive for the developers who enjoyed Atom to migrate to VSCode, I guess), there is no more way to download packages for Atom.
As this fact makes Atom pretty much useless, I wondered if there's an alternative place where I could download the packages like Hydrogen, 'VIMetc. to make myAtom` more useful.
Thanks in advance.

I am a newbie for PowerBuilder and for Windows application. I have few projects which consists corresponding code in it and after merging all that I get the final product. The problem I am facing right now is that I don't know how to make a setup of my Windows app using PowerBuilder. If I can get step by step procedure with tiny explanation, I will be able to achieve it already. Have tried Google but ended up with complex confusion. I have created the .exe, but that .exe does not work on any other computer. So please guys help me out.
Thanks
There are two parts to creating a setup program for your application: defining the files and other resources that need to deployed, and building those resources into a setup executable package.
For defining files and resources, you've made it impossible for anyone to even take a shot by referring to two very different (but similar origins) versions of the product in your tags: PowerBuilder (aka PowerBuilder Classic) and PowerBuilder.NET. The deployment requirements for apps built from each of these is very different. However, even if we knew, the best advice is to go through the manuals and review what is required of the features of your specific application. (e.g. if you don't use rich text, deploying the files required to support it would be a waste). A generic list is, IMHO, just bad advice.
As far as building a setup package goes, the first decision is which package building software to pick (none comes with PowerBuilder). Any Windows setup package builder should do. I've used InstallShield and Inno, vastly preferring the latter (after many years of using the former). I know you want steps to walk you through, but a walk through is impossible before picking the software, and frankly, walk throughs of these setup building software has been done elsewhere much better than I'd do.
The bottom line is that the answer isn't as simple as you seem to have been hoping, but it is attainable.
Good luck,
Terry.
I started working with sample sencha apps. I find it really hard to find typo and errors in my code.
I added the eclipse plugin for auto-complete during coding. Buts its a trial version just like the sencha architect. Am really confused on how the sencha app should be developed.
I want to know the tools that sencha developers are using so that I can deploy and debug effeciently.
Thanks in advance.
The workflow / tools choice when developing an application is a subjective matter so I'm going to talk about my experience, having been a Sencha Touch developer for the last year.
I find it really hard to find typo and errors in my code.
...
Am really confused on how the sencha app should be developed.
This is not a matter of tools in my opinion. Sencha Touch has an unavoidable steep learning curve. You should start with simple examples, and you could ask here when you have specific programming issues (I personally found Sencha Touch forums less useful than stackoverflow).
The most important thing is understanding the basics concepts:
Sencha Touch class system (http://www.sencha.com/learn/sencha-class-system),
How Sencha implements MVC (http://docs.sencha.com/touch/2.2.1/#!/guide/controllers)
(http://docs.sencha.com/touch/2.2.1/#!/guide/views),
Sencha Touch Layouts (http://docs.sencha.com/touch/2.2.1/#!/guide/layouts),
Sencha Touch Components (http://docs.sencha.com/touch/2.2.1/#!/guide/components)
Also all of these guides will be very useful, make sure you understand them and learn to use Sencha Docs, which definetely has some obscure, non explained properties, but should still be your main resource when developing a Sencha Touch app.
Debugging will always be tricky, unfortunately sometimes setting the wrong property on a Component, or misunderstanding how a Component is meant to work, ends up with some obscure var is not defined error. Do not fear to check Sencha Touch source code when this happens, code is well written and usually easy to understand.
Here the tools to use are again Sencha Touch Docs (when hovering on a class title you can examine directly its source code, plus your browser debugging console. Use frequent console.debug() messages, and when something weird happens inside framework classes stop execution with debugger; and step inside source code).
Now back to your question: I have been using the following tools:
NetBeans,
Chrome DevTools,
Chrome Ripple Extension,
Sencha Command (optional)
Compass CSS authoring framework
a couple shell scripts
The IDE is a matter of personal choice, Netbeans has some nice Javascript suggestions: it highlights variables when they are used but not defined in the current scope, or defined but not used, which really helps a lot against typos. It is very heavy in terms of memory usage. I guess Eclipse, or even a lighter one could be equally good.
Chrome is kinda a forced choice if you are on Windows, their DevTools are excellent, make sure you master them, they will be your main working tools. Once again: lot of RAM helps.
Ripple is an invaluable extension that allows you to test your mobile app on different devices and if you are using Phonegap for native deployment it emulates a part of its API on the browser.
Compass is the tool suggested by Sencha to compile their sass files. There is a detailed tutorial on how to setup compass on Sencha Docs.
I have been using Sencha Command but it's not strictly necessary, if you don't care about resources minification (but you should) you will not miss much about it. If you are developing a native app you can make up for the lack of Sencha Command deploy function with a simple shell script that copies html/js/css resources to the assets folder of your Phonegap project.
Another script activates automatically compass watch on the /resources/sass folder at startup, to avoid having to manually do that each time.
Just my two cents, hope it helps.
Anubis covered majority of the bee knees in hand coding Sencha Touch.
I'd like to add a couple more cents into the kitty.
My personal preference for IDE is Sublime Text. Searching through entire projects of code for anything, I've not seen an equal for effectiveness and speed. You can customise everything - especially colours and keybindings. It also has a ludicrous wealth of plugins, including working in correlation to Chrome, as well as Github.
SENCHA GUIDES
Miami Coder Tutorials - great collection of practical tutorials which will help you understand development patterns faster than most other guides. Great for starters.
Figleaf Training can be a little unconventional, but a great free means of learning Sencha Touch and almost everything it is capable of. Great for starters too.
Druck IT - solid collection of guides and ST information. Has links to many other useful sites such as these listed.
Mitchell Simoens - Mitchell is Sencha staff, a quality coder, and his site has some great advice and snippets to help learn. This is where you'll truly learn how to code ST well. Helps towards getting a grasp, but mainly for mid+ knowledge.
Ladysign - one of the Sencha Trainers. Has content that clears up "how to" in many facets other sites and books never even mention. Quality information. This info will get you above basic and flesh out your knowledge and understanding.
Modus Create - Jay Garcia is one of the devs of ST. Modus Create is his enterprise, which contains some useful guides within the blog.
Custom Font Icons - complete guide for 2.2. Very useful.
There's a few other sites that were incredible sources of tidbits through to information on how to code ST professionally. These links above will help immensely though. Above all, read the source code. It is very well documented, as well as being an example in itself of how to use the code. I have learnt ludicrous amounts this way.
GRUNT (with NPM/Node.js)!
Use Grunt! This will automate the vast majority of what you want to do. For example, typing "grunt" in the command line could jshint/jslint your code, concatenate all .js files together, all css files together (including all the compass joy), obfuscate, compress, run a comprehensive set of unit tests (especially Phantom), output to desired location, then add a cherry on top by refreshing your browser window. Add in the grunt watch plugin, and it'll do that every time a file is saved in defined directories. Any bugs in your code - you get accurate specific line numbers where it is broken.
The beauty of grunt is extended by optional alternate commandlines for different tasks. Also, you can specify in the package.json file of a few kB the precise list of plugins you wish to use with the gruntfile you've created, saving megabytes of file transfer. NPM can process that file, and download and install all that is required to operate. Makes for fast setup on another computer.
Side note: Touch Node has come of age. This permits all ST's class structure to develop your serverside javascript.
Want to include Sencha Cmd?
Sencha Cmd (finally) does do a decent job of collecting only the dependent classes from the full library.
grunt-sencha-build
grunt-senchacmd
Alternative for Sencha Cmd
Extend Grunt with Matt Goldspink's grunt-sencha-dependencies which works for both ST and ExtJS, or use grunt-sencha-resolver - this latter one I haven't used.
I had an open-source spare-time project two years ago where I used the free 60 controls by DevExpress, from the link here: https://www.devexpress.com/Products/Free/NetOffer/
I was vey happy with these and I even personally recommended these controls here.
My project now is quite old, but now I want to make some minor changes, and I just experienced, to my surprise, that I will no longer be able to build it, because I took a dependency on those controls. I did not copy these DevXpress libraries locally, so I really lost them.
What can I do about these now missing controls? Does anybody faced the same already? Should I replace them (quite a lot of work, because I do not want to change the UI at all now), or does someone still have these around?
My mind just had a glitch :-/ These DLL's are of course found in my installer package. I just installed my own software from codeplex, where I published it, searched thru the Harddisk and voilà, here the are, listed:
DevExpress.Data.v10.2.cdf-ms
DevExpress.Data.v10.2.dll
DevExpress.Data.v10.2.manifest
DevExpress.Utils.v10.2.cdf-ms
DevExpress.Utils.v10.2.dll
DevExpress.Utils.v10.2.manifest
DevExpress.XtraBars.v10.2.cdf-ms
DevExpress.XtraBars.v10.2.dll
DevExpress.XtraBars.v10.2.manifest
DevExpress.XtraEditors.v10.2.cdf-ms
DevExpress.XtraEditors.v10.2.dll
DevExpress.XtraEditors.v10.2.manifest
DevExpress.XtraTreeList.v10.2.cdf-ms
DevExpress.XtraTreeList.v10.2.dll
DevExpress.XtraTreeList.v10.2.manifest
DevExpress.XtraVerticalGrid.v10.2.cdf-ms
DevExpress.XtraVerticalGrid.v10.2.dll
DevExpress.XtraVerticalGrid.v10.2.manifest
So, just in case, anyone needs those DLL's (The original 60 controls suite consisted of more files, however), you can get them the same way from my installer.
I would guess this is legal, since distribution in my project (with LGPL v2) was also legal.
latest free control is version 11.2 you can download it from github
I have a question about Flash. I am writing my first browser game, and I am trying to decide on a technology.
I have a few requirements:
I don't want to have to pay to write code and a not-complete-crap free IDE would also be good.
I want most (or > 70%) of "normal" computer users to have it installed, so, Unity's pretty much out.
I don't really need performance too much
I need 2D, not 3D
Needs to be able to communicate with the server, and no extra downloads required.
Preferably works with the Facebook platform, but, this isn't a requirment.
Now, I would go with Flash as it fills all of my requirements, but, to my understanding, I need to pay for CS5 to get coding with Flash. Is an alternative around this possible?
Are there any other alternatives I'm missing?
To add onto what ColinE mentioned, FlashDevelop also provides you the ability to download and install the Flex SDK. However, if FlashDevelop as an IDE doesn't work for you, you can also download the Flex SDK yourself.
This is essentially the same thing that's included with Adobe's Flash Builder application, which is basically built on top of Eclipse. This should at least give you a start on creating things in Flash, though you'll be limited to ActionScript 3. I'd suggest sticking with AS3 as it provides a lot of power compared to AS2.
If you do choose to use the Flex SDK, I'll give you a bit of knowledge I've gained since I started using it for developing games. This may be a little long-winded but hopefully it'll answer some of the initial starter questions.
You can develop apps/games using the Flex library but this may increase the size of your SWF file. However, it's worth noting that it's not required to use the library. You can use the compiler (mxmlc) provided in the SDK to build against .as files as well.
From here, there's a few gotchas that might creep in when it comes to assets. Flex provides you the ability to embed assets within your class files. Out of the box, it allows for the embedding of a handful of formats, most notably PNG, TTF, XML and SWF. There's a lot that you'll be able to do with Flex from a code standpoint but it's not very pretty for creating the assets themselves. Primarily, I use the Flash IDE only for cases where a project requires a SWF asset, however, most of my projects tend to use PNG.
When using an embedded SWF asset, you may come across an issue where any code that's included in the asset, such as any hover or animation logic as ActionScript, gets stripped out of the copy embedded in the resulting project's SWF. A workaround for this is forcing the mimetype to "application/octet-stream" and using a Loader object's loadBytes() method.
Finally, you should be able to make some sort of progress provided you have some sort of ActionScript knowledge. There are plenty of resources out there but be aware that a fair amount of them still use AS2. The knowledge can be applied with some modifications but may require some extra legwork to implement. The language is fairly easy to work with.
With all that, I wish you luck. Flash gets a lot of flack these days but even with HTML5 nearing final, there's still a lot of features that it will never be able to touch without leveraging Flash in some way.
Flash, Silervlight or HTML5 will tick pretty much all of those boxes for you, however Silverlight is only installed on ~65% of computers at the moment.
HTML5 can be tough to develop with, so perhaps Flash is your best bet. See the following question which discusses Flash IDEs:
Flash Developer IDE
FlashDevelop is a free development environment for Flash.
I believe your question is about which type of development you should use to get this game going, but I would also urge you to consider the future of each of these software sets, and choose based on what you would like more experience in.
Flash has been holding it's ground pretty well, but I've seen it less and less on major sites these days, and I believe HTML 5 is taking pretty good stabs at it. Even Pandora doesn't use flash anymore, and that was a pretty well designed little flash app (they still use AIR for Pandora One, but not their main site). Instead, like many other websites, it's using HTML and JavaScript.
So, while flash is slowly losing ground to HTML and JavaScript, where does Silverlight stand? Microsoft is still pushing their Silverlight technology, and based on Microsoft's support scheme, they'll still be using it for the next few years at least. At the same time, it's based on the .NET framework, so you'll be gaining some valuable WPF and .NET skills by using Silverlight.
There is no right or wrong decision here, it's really just based on which technology you see yourself using past this product, and which technology you want to learn.
I'd give it a shot in Silverlight, myself, but that's simply because I dislike flash, and there's already too many HTML and JavaScript developers.
edit:
Silverlight is a relatively small 30 second install. I generally hate installing new plugins, but Silverlight is relatively painless, imo.
I notice most of the discussions about Blackberry database options are old, and generally not too informative.
As of today, March 31st, 2010, what is the best, most universally supported, free database option available for Blackberry developers?
I heard SQLite is available for JDE v5, but last I checked, that was still in beta, and I didn't want to commit to developing on a system that is not supported by most of the phones in service.
Thing is, I don't see any dates on these claims. For all I know, the announcements I am reading are from 2008.
So, I am still on v 4.7. I need to use a relational DB for the app I am developing, but there aren't many resources for DB handling available - or at least resources that are useful to me. I find a lot of "tutorials" that assume you know everything there is to know about Blackberry development, or Java. But no complete classes or anything. Many of these examples don't even work. Eclipse gives warnings and errors from code copied and pasted from other people's examples.
I can answer any questions that may assist in this case. Hopefully, this thread will help many BB developers in the future.
Before v5 I don't think there is a native relational database that you can work with on the Blackberry, the closest thing is the Persistant Store API, however I think that there are 3rd party libraries that you can use, like SQL Anywhere.
Depending on the Java dialect supported on your Blackberry version, db4o could also work well for your usecase. It's an object database, quite similar to Perst.
Ok, in case anyone has had similar experiences with this, here is what I have done:
The JAR class path thing was resolved through no help at all from these sites.
What I did to get an outside JAR included in my package was to right click the package name in the navigation menu (Eclipse) - then select Build Path - then add libraries.
From this I was able to modify an existing library to include the JAR for the perst package.
Now I am able to import org.garret.perst.*
We'll see if there are any complications.
Forgive the number of posts, maybe it will help someone else down the way.
