• What is the PastryKit Framework?

  - by Kerrick

  I'm trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out the guide. Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app. When it comes to Javascript, I used the JS Beautifier on (what I assume to be) the framework file and it was over 3,400 lines! Beautified, (again what I assume to be) their implementation of it was over 1,200 lines. On the CSS side, I used Clean CSS on (again what I assume to be) the framework CSS, and it came out to over 700 lines. Their implementation was shy of 500. Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

• How do you refactor a large messy codebase?

  - by Ricket

  I have a big mess of code. Admittedly, I wrote it myself - a year ago. It's not well commented but it's not very complicated either, so I can understand it -- just not well enough to know where to start as far as refactoring it. I violated every rule that I have read about over the past year. There are classes with multiple responsibilities, there are indirect accesses (I forget the technical term - something like foo.bar.doSomething()), and like I said it is not well commented. On top of that, it's the beginnings of a game, so the graphics is coupled with the data, or the places where I tried to decouple graphics and data, I made the data public in order for the graphics to be able to access the data it needs... It's a huge mess! Where do I start? How would you start on something like this? My current approach is to take variables and switch them to private and then refactor the pieces that break, but that doesn't seem to be enough. Please suggest other strategies for wading through this mess and turning it into something clean so that I can continue where I left off!

• Obfuscated Javascript Code from Facebook Application?

• MVVM Listbox DataTemplate SelectedItem

  - by StinkerPeter

  I am using a ListBox with a DataTemplate as shown below (xaml simplified and variable names changed). <ListBox ItemsSource="{Binding Path=ObservCollectionItems}" SelectedItem="{Binding Path=SelectedItemVar, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding SomeVar}" /> <Border> <StackPanel> <Button Content="String1" Command="{Binding DataContext.Command1} RelativeSource={RelativeSource FindAncestor, ListBox, 1}}" /> <Button Content="String2" Command="{Binding DataContext.Command2} RelativeSource={RelativeSource FindAncestor, ListBox, 1}}" /> </StackPanel> </Border> </StackPanel> </DataTemplate> <ListBox.ItemTemplate> </ListBox> I need the SelectedItemVar (dependency property) to update when I click on one of the buttons. SelectedItemVar is then used for the respective button's command. SelectedItemVar does update when I click on the TextBlock or the Border, but not when I click either button. I found a non-MVVM solution to this problem here. I do not want to add code in the file-behind to solve this, as they did in the link. Is there a clean solution that can be done in XAML. Beyond the non-MVVM solutions, I have not found anyone with this problem. I would have thought this was fairly common. Finally, I found this Command="{Binding DataContext.CommandName} RelativeSource={RelativeSource FindAncestor, ListBox, 1} for the Command binding. I do not fully understand what it is doing, but I do know that the command wasn't firing when I was binding directly to CommandName.

• Ternary operator

  - by Antoine Leclair

  In PHP, I often use the ternary operator to add an attribute to an html element if it applies to the element in question. For example: <select name="blah"> <option value="1"<?= $blah == 1 ? ' selected="selected"' : '' ?>> One </option> <option value="2"<?= $blah == 2 ? ' selected="selected"' : '' ?>> Two </option> </select> I'm starting a project with Pylons using Mako for the templating. How can I achieve something similar? Right now, I see two possibilities that are not ideal. Solution 1: <select name="blah"> % if blah == 1: <option value="1" selected="selected">One</option> % else: <option value="1">One</option> % endif % if blah == 2: <option value="2" selected="selected">Two</option> % else: <option value="2">Two</option> % endif </select> Solution 2: <select name="blah"> <option value="1" % if blah == 1: selected="selected" % endif >One</option> <option value="2" % if blah == 2: selected="selected" % endif >Two</option> </select> In this particular case, the value is equal to the variable tested (value="1" = blah == 1), but I use the same pattern in other situations, like <?= isset($variable) ? ' value="$variable" : '' ?>. I am looking for a clean way to achieve this using Mako.

• How to create custom pages (Drupal 6.x)

  - by jc70

  In the template.php file I inserted the code below: I found a tutorial online that gives the code, but I'm confused on how to get it to work. I copied the code below and inserted it into the template.php from the theme HTML5_base. I duplicated the page.tpl.php file and created custom pages -- page-gallery.tpl.php and page-articles.tpl.php. I inserted some text to the files just see that I've navigated to the pages w/ the changes. It looks like Drupal is not recognizing gallery.tpl.php and page-articles.tpl.php. In the template.php there are the following functions: html5_base_preprocess_page() html5_base_preprocess_node() html5_base_preprocess_block() In the tutorial it uses these functions: phptemplate_preprocess_page() phptemplate_preprocess_block() phptemplate_preprocess_node() function phptemplate_preprocess_page(&$vars) { //code block from the Drupal handbook //the path module is required and must be activated if(module_exists('path')) { //gets the "clean" URL of the current page $alias = drupal_get_path_alias($_GET['q']); $suggestions = array(); $template_filename = 'page'; foreach(explode('/', $alias) as $path_part) { $template_filename = $template_filename.'-'.$path_part; $suggestions[] = $template_filename; } $vars['template_files'] = $suggestions; } } function phptemplate_preprocess_node(&$vars) { //default template suggestions for all nodes $vars['template_files'] = array(); $vars['template_files'][] = 'node'; //individual node being displayed if($vars['page']) { $vars['template_files'][] = 'node-page'; $vars['template_files'][] = 'node-'.$vars['node']->type.'-page'; $vars['template_files'][] = 'node-'.$vars['node']->nid.'-page'; } //multiple nodes being displayed on one page in either teaser //or full view else { //template suggestions for nodes in general $vars['template_files'][] = 'node-'.$vars['node']->type; $vars['template_files'][] = 'node-'.$vars['node']->nid; //template suggestions for nodes in teaser view //more granular control if($vars['teaser']) { $vars['template_files'][] = 'node-'.$vars['node']->type.'-teaser'; $vars['template_files'][] = 'node-'.$vars['node']->nid.'-teaser'; } } } function phptemplate_preprocess_block(&$vars) { //the "cleaned-up" block title to be used for suggestion file name $subject = str_replace(" ", "-", strtolower($vars['block']->subject)); $vars['template_files'] = array('block', 'block-'.$vars['block']->delta, 'block-'.$subject); }

• Component based web project directory layout with git and symlinks

  - by karlthorwald

  I am planning my directory structure for a linux/apache/php web project like this: Only www.example.com/webroot/ will be exposed in apache www.example.com/ webroot/ index.php comp1/ comp2/ component/ comp1/ comp1.class.php comp1.js comp2/ comp2.class.php comp2.css lib/ lib1/ lib1.class.php the component/ and lib/ directory will only be in the php path. To make the css and js files visible in the webroot directory I am planning to use symlinks. webroot/ index.php comp1/ comp1.js (symlinked) comp2/ comp2.css (symlinked) I tried following these principles: layout by components and libraries, not by file type and not by "public' or 'non public', index.php is an exception. This is for easier development. symlinking files that need to be public for the components and libs to a public location, but still mirroring the layout. So the component and library structure is also visible in the resulting html code in the links, which might help development. git usage should be safe and always work. it would be ok to follow some procedure to add a symlink to git, but after that checking them out or changing branches should be handled safely and clean How will git handle the symlinking of the single files correctly, is there something to consider? When it comes to images I will need to link directories, how to handle that with git? component/ comp3/ comp3.class.php img/ img1.jpg img2.jpg img3.jpg They should be linked here: webroot/ comp3/ img/ (symlinked ?) If using symlinks for that has disadvantages maybe I could move images to the webroot/ tree directly, which would break the first principle for the third (git practicability). So this is a git and symlink question. But I would be interested to hear comments about the php layout, maybe you want to use the comment function for this.

• php paging class

  - by Stick it to THE MAN

  Can anyone recommend a good PHP paging class? I have searched google, but have not seen anything that matches my requirements. Rather than "rolling my own" (and almost surely reinventing the wheel), I decided to check in here first. First some background: I am developing a website using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10. I am currently using the Propel pager, which is OK, but I recently started using memcache to speed things up a little. At this point, the Propel pager is of little use, as it (AFAIK), only works with Propel objects. What I need is a class th:t meets the following requirents Has clean interface, with separation of concerns, so that the logic to retrieve records from the datasource (e.g. database) is encapsulated in a class (or at least a separate file). Can work with arrays of objects Provides pagination links, and only fetches the data required for the current page. Also, the pagination should 'split' the available page links if there are too many. For example, if there are potentially 1000 possible page links, the pages displayed should be something like FIRST 2,3 ....999 LAST Can return the number of all the records in the table being queried, so that the following links are available FIRST, LAST (this requirement is actually already covered in the previous requirement - but I just wanted to re-emphasise it). Can anyone recommend such a library, if they have used it succesfully in the past? Alternatively, someobe may have 'hacked' (e.g. derived from) the current Propel pager, to get it to do the things I listed about - please let me know.

• Helpful advice on developing a professional MS Word add-on

  - by Dan Tao

  A few months back I put together a simple proof-of-concept piece of software for a small firm with an idea for a document editing tool. The company wanted this tool to be integrated into Microsoft Word, understandably, to maximize its accessibility to the average user. I essentially wrote the underlying library with all of the core functionality as a C# project, and then used VSTO to get it running inside of Word. It felt like a bit of a duct tape solution, really; but then, I have (practically) zero experience developing tools for integration with MS Office, and it was only a proof of concept anyway. Well, the firm was quite pleased with my work overall, and they're looking to move from "proof of concept" to the real deal. Fortunately, as I said, the core functionality is all there and will only need to be somewhat tweaked and enhanced. My main concern is figuring out how to put together an application that will integrate with MS Word in a clean and polished way, and which can be deployed easily in accordance with a regular user's expectations (i.e., simply running an install program and voila, it's there in Word). I seem to remember reading somewhere that nobody uses VSTO for real professional projects. Is this true? False? What are the alternatives? And what are the tips and gotchas that I should be aware of before getting started on this issue of MS Word integration?

• Overflow in table cells

  - by Ezdaroth

  I need to create a chat layout that uses all the available space and scales nicely, but has few fixed sizes. Here's the structure: <table style="width: 100%; height: 100%"> <tr> <td></td> <td style="width: 200px; background: red;"></td> </tr> <tr> <td style="height: 100px; background: blue"></td> <td></td> </tr> </table> However, I want to place a lot of content in the first table cell and I want it to scroll, so it won't expand the table. Is it possible to make it overflow properly, without having a fixed height for the cell? Simply adding overflow: auto doesn't seem to work. PS. I hate tables, but can't figure out a very clean and cross-browser way to do a layout like this with divs and css. If someone can come up with one, I'll gladly use it.

• eclipse show errors but compiles when external makefile

  - by Anthony

  I have some c++ code using CImg and Eigen libraries. At the c++ code I define a plugin like this #define cimg_plugin1 "my_plugin.h" #include "CImg.h" The plugin contains many method definitions that are used at the c++ code. I also have a makefile that when called from the command line (./make), allows me to compile everything, and generates an executable. I want to import this code into a new Eclipse project, and I do it so: NewProjectC++ projectmakefile projectempty project unmark "Use default location", and select the folder containing my code at the filesystem ProjectpropertiesC/C++ Buildunmark "Use default build command" and set it to use my makefile Also in project propertiesC/C++ GeneralPaths and SymbolsAdd paths to folders containing Eigen and CImg Rebuild index Clean project Restart eclipse When I build the project, eclipse tells me I have more than 1000 errors in "my_plugin.h", but it is capable to generate the executable. Even though, I would like to get rid of this errors, because they are annoying. Also, if I want to open the declaration of CImg methods used at the plugin, I can't. I know it has been asked before, but any of the solutions I found were satisfactory for me (most of them enumerated at the previous list). The sources I visited are the following, and I would be really happy if you find and tell me others I didn't see. Eclipse shows errors but project compile fine eclipse C project shows errors (Symbol could not be resolved) but it compiles Eclipse CDT shows some errors, but the project is successfully built http://www.eclipse.org/forums/index.php/t/247954/

• Subclassing ViewPager Breaks Animation

  - by Ryan Thomas

  In my Android application I have an activity which uses a view pager to display 4+ pages (Fragments). I implemented buttons on each screen that move between pages by calling: pager.setCurrentItem(position, true); The view pager and fragments are all working as I desired. I then began looking for a solution to disable user swiping between pages so that the transition between pages in handled by the buttons only. The solution I found was mentioned in a few stackoverflow articles as well as This Blog that suggest subclassing the view pager to intercept touch events to disable swiping. I followed those examples by subclassing the view pager class as follows: public class ViewPager extends android.support.v4.view.ViewPager { private boolean enabled; public ViewPager(Context context, AttributeSet attrs) { super(context, attrs); this.enabled = true; } @Override public boolean onTouchEvent(MotionEvent event) { if (this.enabled) { return super.onTouchEvent(event); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent event) { if (this.enabled) { return super.onInterceptTouchEvent(event); } return false; } public void setSwipingEnabled(boolean enabled) { this.enabled = enabled; } } Using the subclassed view pager and calling setSwipingEnabled(false) works as was desired. The user can no longer move between pages with swipe gestures and I can still move between pages via button clicks by calling setCurrentItem(int position, boolean smoothScroll). However using the subclass breaks the animation between pages. When I call setCurrentItem(position, true) with android.support.v4.view.ViewPager I get very clean scrolling animations between pages. When I make the same call using the subclass the screen has a very brief 'flash' and then automatically draws the new page. I would like to know how to fix the animation while retaining the ability to disable user swiping between pages. I greatly appreciate any help with this. Let me know if you need any additional information. So far I have tested using a Samsung device running 2.3.5 and an AVD emulator targeting Android 2.3.3.

• App hosting Report Viewer crashes on exit after export

  - by Paul Sasik

  We have a .NET Winforms application that hosts the Crystal Reports Viewer control (Version XI). It works well for the most part but when an export of data from the viewer is performed the application will crash on exit and in unmanaged code. The error message is not very useful and just says that an incorrect memory location was accessed. No other info such a specific DLL etc. is provided. This only happens after the viewer is used to export a report to CSV, XML etc. My guess is that at some point in the export process Crystal creates a resource that attempts an action on shut down to a parent window (perhaps) that no longer exists. I've seen a number of memory leak and shut down issues with Crystal but this one's new. Has anyone seen it and come up with a workaround or has ideas for workarounds? So far we've tried explicitly disposing of all crystal-related objects, setting to null and even setting a Thread.Sleep cycle on shut down to "give Crystal time to clean up." Update: The crash happens only on shut down (so not immediate) All export formats work All export files are created properly CR is installed on the same machine as the hosting .NET app not sure about exporting from the IDE... is that even possible?

• How to make HTML layout whitespace-agnostic?

  - by ssg

  If you have consecutive inline-blocks white-space becomes significant. It adds some level of space between elements. What's the "correct" way of avoiding whitespace effect to HTML layout if you want those blocks to look stuck to each other? Example: <span>a</span> <span>b</span> This renders differently than: <span>a</span><span>b</span> because of the space inbetween. I want whitespace-effect to go away without compromising HTML source code layout. I want my HTML templates to stay clean and well-indented. I think these options are ugly: 1) Tweaking text-indent, margin, padding etc. (Because it would be dependent on font-size, default white-space width etc) 2) Putting everything on a single line, next to each other. 3) Zero font-size. That would require overriding font-size in blocks, which would otherwise be inherited. 4) Possible document-wide solutions. I want the solution to stay local for a certain block of HTML. Any ideas, any obvious points which I'm missing?

• MVC Html.ActionLink with post funtionality?

  - by Levitikon

  I'm checking to see if anyone has written an MVC extension for Html.ActionLink that you can pass in Post parameters like such: <% Html.ActionLink("Click me", "Index", "Home", new { MyRouteValue = "123" }, null, new { postParam1 = "a", postParam2 = "b" }); %> That would render the link like normal but having an onClick event that submits an also rendered form with an Action url for the Action, Controller, and Route Values with additional hidden inputs from the Post Parameters like such: <a href="#" onClick="$('#theform').submit(); return false;">Click me</a> <form id="theform" action="/Home/Index/123" method="post"> <input type="hidden" name="postParam1" value="a"> <input type="hidden" name="postParam2" value="b"> </form> I'm looking to redirect users to various pages with potentially a lot of data. Not only from page to page, but from email to page also. This would be highly reusable and I think would clean up a lot of code, and would save a bunch of time writing this if its already floating around out there. I hate recreating the wheel when I don't have to. Thanks!

• Customers angry, fighting unknown DLL dependencies

  - by wheaties

  I'm a one man show developing a C++ Windows application for a customer. Over the past several months we've been running to the same problems with missing DLL dependencies on customer machines. Despite my best efforts something keeps going wrong and we get angry emails back. My boss and my boss's boss are angry with me and the customers aren't happy. I'm hoping you guys can help out and give suggestions/ideas on how to get the deliverables in order. Before some of the obvious: I have no test machine. That is, I can't replicate the customer environment nor attempt to install the app on a "clean" system to catch gotchas before shipping. I've tried using depends.exe to track down what versions of the DLLs my project is dependent upon. I'm shipping our code with the redistributables I've been able to find that way. After that it's an angry customer email waiting game. I'm required to use a third-party DLL which can not be registered (it's buggy as hell.) I'm not supposed to use Install Shield, any other automated installer, or write an install script. I provide written instructions on how to get the app installed (unzip, double click exe file.) I'm tired of taking heat for this stuff. What am I missing that I could be doing? What should I ask in terms of support from my employer? How should I ask for that support in a way that they'll provide it?

• Opening URL in New Tab doesn't work in existing, programmatically-opened New Window (Firefox)

  - by seth

  I am building a web app, for myself, to control some servers on my home network, and discovered what I think is very odd behavior in Firefox. If you open a pop-up, via javascript, in Firefox, is it then impossible to open a new tab, via javascript in that pop-up? If not impossible, how do you do it? Given a clean, default Firefox 3.6.3 installation... If I open a page in Firefox and then call var my_window = window.open('http://www.google.com','_blank','top=10'); A brand new "pop-up" window opens. However, if instead I call var my_window = window.open('http://www.google.com'); A get a new tab. HOWEVER... If I call the first version var my_window = window.open('http://www.google.com','_blank','top=10'); And then in the new "pop-up" that opens, I call var my_window = window.open('http://www.google.com'); It opens a new tab in the original window, not a new tab in the pop-up. This seems very odd, and not intuitive at all. Why would the call in the pop-up open a tab in the "parent" window?

• PHP: how to access variables inside a function that have been declared outside of it?

  - by Chris

  Please, I am very new and have not been confronted with OOP and all this related stuff, which I guess may be related to this issue (public, private, ...). So, any help and suggestions are very appreciated! :) At the very beginning of each page I include a file that starts the SESSION etc, lets call it session.php. In this file session.php, I include a file that contains a function, let's call it function1.php, because I need the function to be available in session.php. However, later in the main page I also include function2.php which needs to access variables set in session.php, so I additionally tried to include session.php in function2.php. The problem is that an error occurs as function1 will be declared multiple times... Fatal error: Cannot redeclare function1() (previously declared in ... So, what would be a more elegant and clean(er) solution for this? How could you solve it? Basically, I'd need to access variables inside a function that have been included in the main page before... Thank you very much in advance!

• Consecutive build of VS2005 and VS2008 C++ projects causes LNK1104 error

  - by TestAccount

  I have VS2005 and VS2008 installed on the same machine. I also have a common codebase that I build using both '05 and '08. For this purpose, I have 2 VC projects.. A '08 project called XYZ_2008.vcproj and a '05 project called XYZ_2005.vcproj, and the corresponding 2 slns as well. Both projects output dlls, libs and pdbs to the same output directory (all with appropriate _2005 and _2008 suffixes). Assuming that I am starting from a clean state, I first open XYZ_2005.sln (containing XYZ_2005.vcproj) in VS2005 and build it successfully. Then I close VS2005. Next, I open XYZ_2008.sln (containing XYZ_2008.vcproj) and build (not rebuild) it. At this point, I get an error saying: LINK : fatal error LNK1104: cannot open file 'mfc80u.lib' If now I rebuild the '08 solution, the error goes away and the build succeeds. The build also succeeds if I directly do a rebuild instead of a build for the '08 sln. In spite of everything being separate, the VS08 build seems to be picking up a MFC8 file (from VS05) instead of a MFC9 file. Can somebody please help out with this issue? Thanks in advance!

Done W: GPG error: file: precise Release: The following signatures were invalid: BADSIG 0976EAF437D05B5 Ubuntu Archive Automatic Signing Key <[email protected]> I had tried use the following steps after google but in vain. sudo apt-get clean cd /var/lib/apt sudo mv lists lists.old sudo mkdir -p lists/partial sudo apt-get update Is there any way to resolve this? And why this error occurs? Thanks a lot.

• Assemblies mysteriously loaded into new AppDomains

  - by Eric

  I'm testing some code that does work whenever assemblies are loaded into an appdomain. For unit testing (in VS2k8's built-in test host) I spin up a new, uniquely-named appdomain prior to each test with the idea that it should be "clean": [TestInitialize()] public void CalledBeforeEachTestMethod() { AppDomainSetup appSetup = new AppDomainSetup(); appSetup.ApplicationBase = @"G:\<ProjectDir>\bin\Debug"; Evidence baseEvidence = AppDomain.CurrentDomain.Evidence; Evidence evidence = new Evidence( baseEvidence ); _testAppDomain = AppDomain.CreateDomain( "myAppDomain" + _appDomainCounter++, evidence, appSetup ); } [TestMethod] public void MissingFactoryCausesAppDomainUnload() { SupportingClass supportClassObj = (SupportingClass)_testAppDomain.CreateInstanceAndUnwrap( GetType().Assembly.GetName().Name, typeof( SupportingClass ).FullName ); try { supportClassObj.LoadMissingRegistrationAssembly(); Assert.Fail( "Should have nuked the app domain" ); } catch( AppDomainUnloadedException ) { } } [TestMethod] public void InvalidFactoryMethodCausesAppDomainUnload() { SupportingClass supportClassObj = (SupportingClass)_testAppDomain.CreateInstanceAndUnwrap( GetType().Assembly.GetName().Name, typeof( SupportingClass ).FullName ); try { supportClassObj.LoadInvalidFactoriesAssembly(); Assert.Fail( "Should have nuked the app domain" ); } catch( AppDomainUnloadedException ) { } } public class SupportingClass : MarshalByRefObject { public void LoadMissingRegistrationAssembly() { MissingRegistration.Main(); } public void LoadInvalidFactoriesAssembly() { InvalidFactories.Main(); } } If every test is run individually I find that it works correctly; the appdomain is created and has only the few intended assemblies loaded. However, if multiple tests are run in succession then each _testAppDomain already has assemblies loaded from all previous tests. Oddly enough, the two tests get appdomains with different names. The test assemblies that define MissingRegistration and InvalidFactories (two different assemblies) are never loaded into the unit test's default appdomain. Can anyone explain this behavior?

• What is an elegant way to set up a leiningen project that requires different dependencies based on the build platform?

  - by Savanni D'Gerinel

  In order to do some multi-platform GUI development, I have just switched from GTK + Clojure (because it looks like the Java bindings for GTK never got ported to Windows) to SWT + Clojure. So far, so good in that I have gotten an uberjar built for Linux. The catch, though, is that I want to build an uberjar for Windows and I am trying to figure out a clean way to manage the project.clj file. At first, I thought I would set the classpath to point to the SWT libraries and then build the uberjar. This would require that I set a classpath to the SWT libraries before running the jar, but I would likely need a launcher script, anyway. However, leiningen seems to ignore the classpath in this instance because it always reports that Currently, project.clj looks like this for me: (defproject alyra.mana-punk/character "1.0.0-SNAPSHOT" :description "FIXME: write" :dependencies [[org.clojure/clojure "1.2.0"] [org.clojure/clojure-contrib "1.2.0"] [org.eclipse/swt-gtk-linux-x86 "3.5.2"]] :main alyra.mana-punk.character.core) The relevant line is the org.eclipse/swt-gtk-linux-x86 line. If I want to make an uberjar for Windows, I have to depend on org.eclipse/swt-win32-win32-x86, and another one for x86-64, and so on and so forth. My current solution is to simply create a separate branch for each build environment with a different project.clj. This seems kinda like using a semi to deliver a single gallon of milk, but I am using bazaar for version control, so branching and repeated integrations are easy. Maybe the better way is to have a project.linux.clj, project.win32.clj, etc, but I do not see any way to tell leiningen which project descriptor to use. What are other (preferably more elegant) ways to set up such an environment?

• How to prevent BeautifulSoup from stripping lines

  - by Oli

  I'm trying to translate an online html page into text. I have a problem with this structure: <div align="justify"><b>Available in <a href="http://www.example.com.be/book.php?number=1"> French</a> and <a href="http://www.example.com.be/book.php?number=5"> English</a>. </div> Here is its representation as a python string: '<div align="justify"><b>Available in \r\n<a href="http://www.example.com.be/book.php?number=1">\r\nFrench</a>; \r\n<a href="http://www.example.com.be/book.php?number=5">\r\nEnglish</a>.\r\n</div>' When using: html_content = get_html_div_from_above() para = BeautifulSoup(html_content) txt = para.text BeautifulSoup translate it (in the 'txt' variable) as: u'Available inFrenchandEnglish.' It probably strips each line in the original html string. Do you have a clean solution about this problem ? Thanks.

• regular expression for emails NOT ending with replace script

  - by corroded

  I'm currently modifying my regex for this: http://stackoverflow.com/questions/2782031/extracting-email-addresses-in-an-html-block-in-ruby-rails basically, im making another obfuscator that uses ROT13 by parsing a block of text for all links that contain a mailto referrer(using hpricot). One use case this doesn't catch is that if the user just typed in an email address(without turning it into a link via tinymce) So here's the basic flow of my method: 1. parse a block of text for all tags with href="mailto:..." 2. replace each tag with a javascript function that changes this into ROT13 (using this script: http://unixmonkey.net/?p=20) 3. once all links are obfuscated, pass the resulting block of text into another function that parses for all emails(this one has an email regex that reverses the email address and then adds a span to that email - to reverse it back) step 3 is supposed to clean the block of text for remaining emails that AREN'T in a href tags(meaning it wasn't parsed by hpricot). Problem with this is that the emails that were converted to ROT13 are still found by my regex. What i want to catch are just emails that WEREN'T CONVERTED to ROT13. How do i do this? well all emails the WERE CONVERTED have a trailing "'.replace" in them. meaning, i need to get all emails WITHOUT that string. so far i have this regex: /\b([A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}('.replace))\b/i but this gets all the emails with the trailing '.replace i want to get the opposite and I'm currently stumped with this. any help from regex gurus out there? MORE INFO: Here's the regex + the block of text im parsing: http://www.rubular.com/r/NqXIHrNqjI as you can see, the first two 'email addresses' are already obfuscated using ROT13. I need a regex that gets the emails [email protected] and [email protected]

• Streaming Youtube Videos

  - by Vinay

  Hi All, I am writing an application to play the youtube videos using streaming. First method: I am getting the RTSP URL to the video using GData APIs. Here is the code to play the RTSP url. VideoView mVideoView = new VideoView(this); setContentView(mVideoView); mVideoView.setVideoURI(Uri.parse("rtsp://rtsp2.youtube.com/CiILENy73wIaGQkDwpjrUxOWQBMYESARFEgGUgZ2aWRlb3MM/0/0/0/video.3gp")); mVideoView.start(); But it throws error on both G1 device and emulator (Emulator has some firewall problem as per mailing list) Here is the error message ERROR/PlayerDriver(35): Command PLAYER_INIT completed with an error or info PVMFFailure Second method: A hack way to get the path of 3gp file from http://www.youtube.com/get_video?v=&t=<&<.. After getting the file path and I can call setVideoURI and it plays fine. But it is a hack way to achieve the requirement. I have checked the Youtube App also, it also does the hack way to play the youtube url.(Checked with logcat) I have tried changing from VideoView to MediaPlayer but no change in the error. Is there a "Clean" way to do this? Please let me know your thoughts.
