• Can JSON be made easily and safely editable by the non-technical Excel crowd?

  - by glitch

  I'm looking for a data storage format that's very intuitive and easy to edit. It should be ideally targeted towards the same crowd as Excel. At the same time I would like the data structure to be a tree. Ideally this would be JSON, since it offers both the tree aspect and allows for more interesting constructs like arrays. That and parsing libraries for JSON are ubiquitous, so I don't have to reinvent the wheel. The problem is that, at least with a non-specialized text editor, JSON is a giant pain to edit for a non-technical user. I'm thinking along the lines of someone who might have used Excel in the past, but never a real text editor. Someone who might not be comfortable with the idea of preserving JSON syntax by hand. Are there data formats out there that would fit this profile? I'd very much prefer this to be a JSON actually, but then it would require a solid editing tool that would hide the underlying implementation from the user. Think Excel and how it abstracts CSV syntax from the user. The reason I'm looking for something like this is because the team has been working with pretty hierarchical data for a while now and we've hit the limits of how easy it is to represent in simple CSVs without having to create complex rules for how represent hierarchy semantics from each row. Any suggestions?

• Why don't C++ Game Developers use the boost library?

  - by James

  So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point). But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me. Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else? I was about to ask this on stack overflow, but I figured the question is better asked here. EDIT : I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience. Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?

• De-index URL paremeters

  - by Doug Firr

  Upon reading over this question is lengthy so allow me to provide a one sentence summary: I need to get Google to de-index URLs that have certain parameters appended I have a website example.com with language translations. There used to be many translations but I deleted them all so that only English (Default) and French options remain. When one selects a language option a parameter is aded to the URL. For example, the home page: https://example.com (default) https://example.com/main?l=fr_FR (French) I added a robots.txt to stop Google from crawling any of the language translations: # robots.txt generated at http://www.mcanerin.com User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /*?l= So any pages containing "?l=" should not be crawled. I checked in GWT using the robots testing tool. It works. But under html improvements the previously crawled language translation URLs remain indexed. The internet says to add a 404 to the header of the removed URLs so the Googles knows to de-index it. I checked to see what my CMS would throw up if I visited one of the URLs that should no longer exist. This URL was listed in GWT under duplicate title tags (One of the reasons I want to scrub up my URLS) https://example.com/reports/view/884?l=vi_VN&l=hy_AM This URL should not exist - I removed the language translations. The page loads when it should not! I played around. I typed example.com?whatever123 It seems that parameters always load as long as everything before the question mark is a real URL. So if Google has indexed all these URLS with parameters how do I remove them? I cannot check if a 404 is being generated because the page always loads because it's a parameter that needs to be de-indexed.

• Acceptable placement of the composition root using dependency injection and inversion of control containers

  - by Lumirris

  I've read in several sources including Mark Seemann's 'Ploeh' blog about how the appropriate placement of the composition root of an IoC container is as close as possible to the entry point of an application. In the .NET world, these applications seem to be commonly thought of as Web projects, WPF projects, console applications, things with a typical UI (read: not library projects). Is it really going against this sage advice to place the composition root at the entry point of a library project, when it represents the logical entry point of a group of library projects, and the client of a project group such as this is someone else's work, whose author can't or won't add the composition root to their project (a UI project or yet another library project, even)? I'm familiar with Ninject as an IoC container implementation, but I imagine many others work the same way in that they can scan for a module containing all the necessary binding configurations. This means I could put a binding module in its own library project to compile with my main library project's output, and if the client wanted to change the configuration (an unlikely scenario in my case), they could drop in a replacement dll to replace the library with the binding module. This seems to avoid the most common clients having to deal with dependency injection and composition roots at all, and would make for the cleanest API for the library project group. Yet this seems to fly in the face of conventional wisdom on the issue. Is it just that most of the advice out there makes the assumption that the developer has some coordination with the development of the UI project(s) as well, rather than my case, in which I'm just developing libraries for others to use?

• "Walking" along a rotating surface in LimeJS

  - by Dave Lancea

  I'm trying to have a character walk along a plank (a long, thin rectangle) that works like a seesaw, being rotated around a central point by box2d physics (falling objects). I want the left and right arrow keys to move the player up and down the plank, regardless of it's slope, and I don't want to use real physics for the player movement. My idea for achieving this was to compute the coordinate based on the rotation of the plank and the current location "up" or "down" the board. My math is derived from here: http://math.stackexchange.com/questions/143932/calculate-point-given-x-y-angle-and-distance Here's the code I have so far: movement = 0; if(keys[37]){ // Left movement = -3; } if(keys[39]){ // Right movement = 3; } // this.plank is a LimeJS sprite. // getRotation() Should return an angle in degrees var rotation = this.plank.getRotation(); // this.current_plank_location is initialized as 0 this.current_plank_location += movement; var x_difference = this.current_plank_location * Math.cos(rotation); var y_difference = this.current_plank_location * Math.sin(rotation); this.setPosition(seesaw.PLANK_CENTER_X + x_difference, seesaw.PLANK_CENTER_Y + y_difference); This code causes the player to swing around in a circle when they are out of the center of the plank given a slight change in rotation of the plank. Any ideas on how I can get the player position to follow the board position?

• Why is my model's scale changing after rotating it?

  - by justnS

  I have just started a simple flight simulator and have implemented Roll and pitch. In the beginning, testing went very well; however, after about 15-20 seconds of constantly moving the thumbsticks in a random or circular motion, my model's scale begins to grow. At first I thought the model was moving closer to the camera, but i set break points when it was happening and can confirm the translation of my orientation matrix remains 0,0,0. Is this a result of Gimbal Lock? Does anyone see an obvious error in my code below? public override void Draw( Matrix view, Matrix projection ) { Matrix[] transforms = new Matrix[Model.Bones.Count]; Model.CopyAbsoluteBoneTransformsTo( transforms ); Matrix translateMatrix = Matrix.Identity * Matrix.CreateFromAxisAngle( _orientation.Right, MathHelper.ToRadians( pitch ) ) * Matrix.CreateFromAxisAngle( _orientation.Down, MathHelper.ToRadians( roll ) ); _orientation *= translateMatrix; foreach ( ModelMesh mesh in Model.Meshes ) { foreach ( BasicEffect effect in mesh.Effects ) { effect.World = _orientation * transforms[mesh.ParentBone.Index]; effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } mesh.Draw(); } } public void Update( GamePadState gpState ) { roll = 5 * gpState.ThumbSticks.Left.X; pitch = 5 * gpState.ThumbSticks.Left.Y; }

• Alpha From PNGs Butchered

  - by ashes999

  I have a pretty vanilla Monogame game. I'm using PNG for all my sprites (made in Photoshop). I noticed that XNA is butchering the aliasing; no matter what I do, my graphics appear jaggedy. Below is a screenshot. The bottom half is what XNA shows me when I zoom in 2X using a Matrix on my GraphicsDevice (to make the effect more obvious). The top is when I pasted the same sprites from Photoshop and scaled them to 200%. Note that partially transparent pixels are turning whiteish. Is there a way to fix this? What am I doing wrong? Here's the relevant call to draw to the SpriteBatch: spriteBatch.Draw(this.texture, this.positionVector, null, Color.White, this.Angle, this.originVector, 1f, SpriteEffects.None, 0f); (this.positionVector can easily be Vector.Zero; Color.White as 100% alpha, I think; this.Angle can be a real angle (small > in the image) or zero (the orb itself).

• An experiment: unlimited free trial

  - by Alex.Davies

  The .NET Demon team have just implemented an experiment that is quite a break from Red Gate's normal business model. Instead of the tool expiring after the trial period, it now continues to work, but with a new message that appears after the tool has saved you a certain amount of time. The rationale is that a user that stops using .NET Demon because the trial expired isn't doing anyone any good. We'd much rather people continue using it forever, as long as everyone that finds it useful and can afford it still pays for it. Hopefully the message appearing is annoying enough to achieve that, but not for people to uninstall it. It's true that many companies have tried it before with mixed results, but we have a secret weapon. The perfect nag message? The neat thing for .NET Demon is that we can easily measure exactly how much time .NET Demon has saved you, in terms of unnecessary project builds that Visual Studio would have done. When you press F5, the message shows you the time saved, and then makes you wait a shorter time before starting your application. Confronted with the truth about how amazing .NET Demon is, who can do anything but buy it? The real secret though, is that while you wait, .NET Demon gives you entertainment, in the form of a picture of a cute kitten. I've only had time to embed one kitten so far, but the eventual aim is for a random different kitten to appear each time. The psychological health benefits of a dose of kittens in the daily life of the developer are obvious. My only concern is that people will complain after paying for .NET Demon that the kittens are gone.

• The MsC gray zone: How to deal with the "too unexperienced on engineering/too under-qualified for research" situation?

  - by Hunter2

  Last year I've got a MsC degree on CS. On the beginning of the MsC course, I was keen on moving on with research and go for a PhD. However, as the months passed, I started to feel the urge to write software that people would, well, actually use. The programming bug had bitten me, again. So, I decided that before deciding on getting a PhD degree, I would spend some time on the "real world", working as a software developer. Sadly, most companies here in Brazil are "services" companies that seem to be stuck on the 80s when it comes to software development. I have to fend off pushy managers, less-than-competent coworkers and outrageous software requirements (why does everyone seem to need a 50k Oracle license and a behemoth Websphere AS for their CRUD applications?) on a daily basis, and even though I still love software development, the situation is starting to touch a nerve. And, mind you, I'm already lucky for getting a job at a place that isn't a plain software sweatshop. Sure, there are better places around here or I could always try my luck abroad, but then I hit the proverbial brick wall: Sorry, you're too unexperienced as a developer and too under-qualified as a researcher I've already heard this, and variations of that, multiple times. Research position recruiters look for die-hard, publication-ridden, rockstar PhDs, while development position recruiters look for die-hard, experience-ridden, rockstar programmers. To most, my MsC degree seems like a minor bump on my CV (and an outright waste of time for some). Applying for abroad positions is even harder, since the employer would have to deal of the hassle of a VISA process, which I understand that, sometimes, is too much. Now I'm feeling I've reached a dead-end. I'm certain that development (and not research) is my thing, so should I just dismiss my MsC (or play it as a "trump card") and play the "big fish on a small pond" role while I gather some experience and contribute on some open-source projects as a plus? Is there a better way to handle this?

• Live programming help

  - by frazras

  This idea has been floating around my head for a few years. I started some work on it but I just want to know if it is feasible, sensible, or if there is something else like it out there. Dont want to know I was wasting time on a solved issue. Whenever I have a programming issue, this is my sequence: Google it!: That usually brings up a lot of things: blogs, forums, stackoverflow, stackexchange, and even the official docs of the language/framework/cms. Ask on IRC: I format my question and try to get people on IRC to help me. Make a post: I create a post on forums/stackoverflow/stackexchange or shout on twitter with hashtags. Now a lot of the time I am in the middle of a project with a deadline. So I want answers NOW!!! Sometimes just 5-15 minutes worth of attention. Usually by the time I am failing at getting answers at #2, I am imagining how many people are ONLINE NOW with the skill and my exact answer but playing video games, watching youtube or idling online. However, if they were motivated, they would invest the 15 mintes helping me, that would make a world of a difference. I am even in positions where I would PAY for that 15 minutes of instant help. If your rate is as much as $100/hour (relatively good programmer) that is $25 that might save me 3 hours. This help would be live, text chat/skype/phone/screenshare. Should I continue developing this idea or is there a better alternative out there? Or is this even an unfeasible idea?

• How to SEO Optimize Javascript Image Loader?

  - by skibulk

  I am building an image-centric catalog website. It catalogs collectible gaming cards numbering 100,000+ pages. Competitor sites recieve millions of hits each month, so with the possibility of excessive traffic, I need to moderate image bandwidth while also optimizing for image SEO. I'm looking for some tips on doing so. Each page on the site features one card with appropriate tags and descriptions. There are however four images for each card - one on matte cardstock, one on foil cardstock, one digital, and one digital foil. In a world with unlimited bandwidth and no-wait page loads, I'd simply embed all four images on the main product page with titles, alt tags, and captions to rank them according to their version keyword. In reality a javascript gallery image loader seems appropriate. Here is a simplified example of my current code. Would this affect SEO in any way? Should I be doing anything differently? Note that I don't want to create a page for each image as I'd have to duplicate the card tags and descriptions on each one, diluting PR for the main page. Thanks for any insight! <script type="text/javascript"> document.write(' <img src="thumbnail1.jpg" data-src="version1.jpg"> <img src="thumbnail2.jpg" data-src="version2.jpg"> <img src="thumbnail3.jpg" data-src="version3.jpg"> <img src="thumbnail4.jpg" data-src="version4.jpg"> '); </script> <noscript> <img src="version1.jpg"> <img src="version2.jpg"> <img src="version3.jpg"> <img src="version4.jpg"> </noscript>

• How can I make myself better at programming working at a shi* job ?

  - by Scrooge

  I recently graduated with an Engineering degree in Computer Science, but my employer (a mid-sized software company) is not using my logical and programming skills. I want to move to a better opportunity but how do I do that since my experience here is not going to count as much? How do I get a better programming job? The worst part is that I am still reading from books (and not writing code myself) even after I have started working. They are paying me a standard entry level Indian IT job rate but I really dont care. It's not worth it. Please advise as to how I can do something worthwhile. (I have studied C++; Core Java; Ruby On Rails ..made a couple of academic projects but no relevant practical real world experience). Just to make things easier .. let me list a few basic queries How I get better at programming without a good project at my company? Please suggest projects where I can learn to write practical code (platform doesn't matter) Best place to take part in open source development? Is it possible that I earn slightly more while I learn? (apart from my sh** job I mean) What kind of practical projects are best suited for me? (ie for an entry level programmer)

• Desktop application, dependency injection

  - by liori

  I am thinking of applying a real dependency injection library to my toy C#/GTK# desktop application. I chose NInject, but I think this is irrelevant to my question. There is a database object, a main window and several utility window classes. It's clear that I can inject the database into every window object, so here DI is useful. But does it make sense to inject utility window classes into other window classes? Example: I have classes such as: class MainWindow {…} class AddItemWindow {…} class AddAttachmentWindow {…} class BrowseItemsWindow {…} class QueryBuilderWindow {…} class QueryBrowserWindow {…} class PreferencesWindow {…} … Each of the utility classes can be opened from MainWindow. Some utility windows can also be opened from other utility windows. Generally, there might be a really complex graph of who can open whom. So each of those classes might need quite a lot of other window classes injected. I'm worried that such usage will go against the suggestion not to inject too many classes at once and become a code smell. Should I use some kind of a service locator object here?

• Install GRUB to Ubuntu Partition

  - by Noel

  So my computer has the following partitions: /dev/sda -- (I know this isn't a real partition, but more so the boot loader) /dev/sda1 -- (Windows 7 Boot Loader) /dev/sda3 -- (Windows 7) /dev/sda4 -- (Data partition, NTFS) that means i have /dev/sda2 as free space. I do not want to change the MBR of the computer. I would like /dev/sda2 to contain GRUB AND Ubuntu. So ideally when I turn my computer on, BIOS would ask if I'd like to boot Windows 7 or Ubuntu(or Grub or partition 2), and I could choose either one. But I would like Grub and Ubuntu to be on the same partition, so they will not interfere in any way with windows or window's boot loader/partition (sda3) How can I do this? Catch: when formatting partitions, Ubuntu does not give me the option to make them virtual partitions, so that makes things harder. I tried: installing Ubuntu to /dev/sda2 (which I formatted as ext4) and then told the Ubuntu installer to install the bootloader to /dev/sda2. But when I select "Ubuntu" from BIOS's boot selection, it loads a black screen and says "invalid arch independent ELF magic grub rescue _" and allows me to input stuff. How can I fix this, or tell my computer where Grub is?

• Incorporating libs into module pattern

  - by webnesto

  I have recently started using require.js (along with Backbone.js, jQuery, and a handful of other JavaScript libs) and I love the module pattern (here's a nice synopsis if you're unfamiliar: http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth). Something I'm running up against is best practices on incorporating libs that don't (out of the box) support the module pattern. For example, jQuery without modification is going to load into a global jQuery variable and that's that. Require.js recognizes this and provides an example project for download with a (slightly) modified version of jQuery to incorporate with a require.js project. This goes against everything I've ever learned about using external libs - never modify the source. I can list a ton of reasons. Regardless, this is not an approach I'm comfortable with. I have been using a mixed approach - wherein I build/load the "traditional" JS libraries in a "traditional" way (available in the global namespace) and then using the module pattern for all of my application code. This seems okay to me, but it bugs me because one of the real beauties of the module pattern (no globals) is getting perverted. Anyone else got a better solution to this problem?

• Is learning how to use C (or C++) a requirement in order to be a good (excellent) programmer?

  - by blueberryfields

  When I first started to learn how to program, real programmers could write assembly in their sleep. Any serious schooling in computer science would include a hefty bit of training and practice in programming using assembly. That has since changed, to the point where I see Computer Science degrees with assembly, if included at all, is relegated to one assignment, and one chapter, for a total of two weeks' work out of 4 years' schooling. C/C++ programming seems to have followed a similar path. I'm no longer surprised to interview university graduates who have not spent more than two weeks programming in C++, and have only read of C in a book somewhere. While the most serious CS degrees still seem to include significant time learning and using one or both of the languages, the trend is clearly towards less enforced C/C++ in school. It's clearly possible to make a career producing good work without ever reading or writing a single line of C or C++ code. Given all of that, is learning the two languages worth the effort? Are they at all required to excel? (beyond the obvious, non-language specific advice, such as "a good selection of languages is probably important for a comprehensive education", and "it's probably a good idea to keep trying out and learning new languages throughout a programmers' career, just to stretch the gray cells")

• Logic / Render phases with a single thread

  - by DevilWithin

  The question I have may generate different opinions from different developers, but I'd still like to have an answer on this. Its all about the updating and rendering steps of the game loop, and their use under multi and single threaded environments. Currently, there is one thread running, which takes care of sequentially executing events , logic and rendering. Sometimes, the logic part may wish to change the game state to something else, and in between do some loading of files. The result is that the game hangs completely while loading, and then proceeds to normal rendering of the new state. To go around this, i could make another thread, do the loading there while the main thread renders a smooth loading animation, and then proceed normally. The real question is about if i don't create another thread. I could refresh the screen from the logic thread, and provide some basic loading screen, which could be not so smoothly updated while the files load. In fact, this approach is not loved by a lot of developers, as it scrambles render code in the logic step, which may cause problems of different sorts.. Hope its clear!

• Oracle SOA Suite for healthcare integration Dashboard

  - by Nitesh Jain

  Oracle SOA Suite Healthcare came up with a new way of monitoring where user can configure a dashboard and follow the dynamic runtime changes.Oracle SOA Suite for healthcare integration dashboards display information about the current health of the endpoints in a healthcare integration application. You can create and configure multiple dashboards as needed to monitor the status and volume metrics for the endpoints you have defined. The Dashboards reflects changes that occur in the runtime repository, such as purging runtime instance data, new messages processed, and new error messages. You can display data for various time periods, and you can manually refresh the data in real time or set the dashboard to automatically refresh at set intervals.Dashboard shows the following information: Status: The current status of the endpoint, such as Running, Idle, Disabled, or Errors. Messages Sent: The number of messages sent by the endpoint in the specified time period. Messages Received: The number of messages received by the endpoint in the specified time period. Errors: The number of messages with errors for the endpoint in the given time period. Last Sent: The date and time the last message was sent from the endpoint. Last Received: The date and time the last message was received from the endpoint. Last Error: The date and time of the last error for the endpoint.  It also shows the detailed view of a specific Endpoint The document type. The number of messages received per second. The total number of message processed in the specified time period. The average size of each message.

• What kind of language will replace C++ as C++ replaced C ? [closed]

  - by jokoon

  I think I'm not totally wrong when thinking that C++0x (or C++1x) is still C++, just better, with functionnalities coming from boost. I can't stop thinking that computer sciences, even with all that has been made so far, have to evolve again. I don't really like D since it just try to be some sort of "what C++ should have been", and Go seems to be too sophisticated when I dig a little into it, especially after watching some presentation video like this one http://www.youtube.com/watch?v=rKnDgT73v8s The first thing that come into my mind is a new kind of syntax to directly handle specific datatypes and containers such as map, vectors, queues... What kind of things are researchers thinking about ? What are the real features that could make C++ better or a new C-like language could invent ? Does Go features such things ? Would there be a new kind of syntax that would "unbloat" C++ while keeping its advantages ? Could C++ have some of the interesting stuff of languages such as C# and ObjC ? EDIT: Please consider that I'm talking about a system language, not a VM/CLI/bytecode thing.

• Why do programmers write closed source applications and then make them free? [closed]

  - by Ken

  As an entrepreneur/programmer who makes a good living from writing and selling software, I'm dumbfounded as to why developers write applications and then put them up on the Internet for free. You've found yourself in one of the most lucrative fields in the world. A business with 99% profit margin, where you have no physical product but can name your price; a business where you can ship a buggy product and the customer will still buy it. Occasionally some of our software will get a free competitor, and I think, this guy is crazy. He could be making a good living off of this but instead chose to make it free. Do you not like giant piles of money? Are you not confident that people would pay for it? Are you afraid of having to support it? It's bad for the business of programming because now customers expect to be able to find a free solution to every problem. (I see tweets like "is there any good FREE software for XYZ? or do I need to pay $20 for that".) It's also bad for customers because the free solutions eventually break (because of a new OS or what have you) and since it's free, the developer has no reason to fix it. Customers end up with free but stale software that no longer works and never gets updated. Customer cries. Developer still working day job cries in their cubicle. What gives? PS: I'm not looking to start an open-source/software should be free kind of debate. I'm talking about when developers make a closed source application and make it free.

• Advice on software infrastructure for a FLOSS bounty site

  - by michaeljt

  I am planning to set up a simple web site where people can offer bounties for work on FLOSS projects. Unfortunately I have no experience at web development (I am a C/C++ developer), so I was hoping someone might be able to suggest out-of-the-box packages (preferably Debian ones) I could use to build the site from. My idea of how the site would work is to keep things as simple as possible. The person proposing a bounty would enter a description with relevant links (particularly to a bugtracker entry with the project the work is to be done on, where the real discussion and work would take place) and information and place an initial contribution. Other people would be able to add (donate, not pledge) contributions, but any discussion would take place on the project's bugtracker. I am also planning to run a mailing list rather than a forum (at least initially), so that is not a requirement. Paypal seems to me to be the handiest payment mechanism. So overall what I need is probably a simple interface with Paypal integration and a simple database backend. I hope this is the right place for my question, if not I would be grateful for pointers to somewhere better. And of course, this is purely about the technical side, though I am more than happy to discuss other aspects of the project elsewhere.

• Game Review: Monument Valley

  Once again, it was a tweet that caught my attention... and the official description on the Play Store sounds good, too. "In Monument Valley you will manipulate impossible architecture and guide a silent princess through a stunningly beautiful world. Monument Valley is a surreal exploration through fantastical architecture and impossible geometry. Guide the silent princess Ida through mysterious monuments, uncovering hidden paths, unfolding optical illusions and outsmarting the enigmatic Crow People." So, let's check it out. What an interesting puzzle game Once again, I left some review on the Play Store: "Beautiful but short distraction Woohoo, what a great story behind the game. Using optical illusions and impossible geometries in this fantastic adventure of the silent princess just puts all the pieces perfectly together. Walking the amazing paths in the various levels and solving the riddles gives some decent hours of distraction but in the end you might have the urge to do more..." I can't remember exactly when and who tweeted about the game but honestly it caught my attention based on the simplicity of the design and the aspect that it seems to be an isometric design. The game relies heavily on optical illusions in order to guide to the silent princess Ida through her illusory adventure of impossible architecture and forgiveness. The game is set like a clockwork and you are turning, flipping and switching elements on the paths between the doors. Unfortunately, there aren't many levels and the game play lasted only some hours. Maybe there are more astonishing looking realms and interesting gimmicks in future versions.

• What conventions or frameworks exist for MVVM in Perl?

  - by Will Sheppard

  We're using Catalyst to render lots of webforms in what will become a large application. I don't like the way all the form data is confusingly into a big hash in the Controller, before being passed to the template. It seems jumbled up and messy for the template. I'm sure there are real disadvantages that I haven't described properly... Are there? One solution is to just decide on a convention for the hash, e.g.: { defaults => { type => ['a', 'b', 'c'] }, input => { type => 'a' }, output => { message => "2 widgets found of type a", widgets => [ 'foo', 'bar' ] } } Another way is to store the page/form data as attributes in a class (a ViewModel?), and pass a whole object to the template, which it could use like this: <p class="message">[% model.message %]<p> [% FOREACH widget IN model.widgets %] Which way is more flexible for large applications? Are there any other solutions or existing Catalyst-compatible frameworks?
