  • Creating a shared library that might be used with desktop applications and web projects

    - by dreza
    I have been involved in a number of MVC.NET and c# desktop projects in our company over the last year or so while also managing to kept my nose poked into other projects (in a read-only learning capacity of course). From this I've noticed that across the various projects and teams there is a-lot of functionality that has been well designed against good interfaces and abstractions. Because we tend to like our own work at times, I noticed a couple of projects had the exact same class, method copied into it as it had obviously worked on one and so was easily moved to a new project (probably by the same developer who originally wrote it) I mentioned this fact in one of our programmer meetings we have occasionally and suggested we pull some of this functionality into a core company library that we can build up over time and use across multiple projects. Everyone agreed and I started looking into this possibility. However, I've come across a stumbling block pretty early on. Our team primarily focuses on MVC at the moment and we have projects mainly in 2.0 but are starting to branch to 3.0. We also have a number of desktop applications that might benefit from some shared classes and basic helper methods. Initially when creating this DLL I included some shared classes that could be used across any project type (Web, Client etc) but then I started looking at adding some shared modules that would be useful in our MVC applications only. However this meant I had to include a reference to some Microsoft Web DLL's in order to leverage some of the classes I was creating (at this stage MVC 2.0). Now my issue is that we have a shared DLL that has references to web specific libraries that could also possibly be used in a client application. Not only that, our DLL referenced initially MVC 2.0 and we will eventually move onto MVC 3.0 for all projects. But alot of the classes in this library I expect to still be relevant to MVC 3 etc Our code within this DLL is separated into it's own namespaces such as: CompanyDLL.Primitives CompanyDLL.Web.Mvc CompanyDLL.Helpers etc etc So, my questions are: Is it OK to do a shared library like this, or if we have web specific features in it should we create a separate web DLL only targeted at a specific framework or MVC version? If it's OK, what kind of issues might we face when using the library that references MVC 2 in a MVC 3 project for example. I would be thinking that we might run into some sort of compatibility issue, or even issues where the developers using the library doesn't realize they need MVC 2.0 libraries. They might only want to use some of the generic classes etc The concept seemed like a good idea at the time, but I'm starting to think maybe it's not really a practical solution. But the number of times I've seen copied classes and methods across projects because they are proven tested code is a bit unnerving to be perfectly honest!

  • How can I move a library inside a project's source tree and compiling static binaries?

    - by AbrahamVanHelpsing
    How can I move a library inside a project's source tree and compiling static binaries? I want to use a particular tool that utilizes ANCIENT binaries without upgrading it's API usage. This way I can use the old libraries inside the single binary without wrecking the local host environment. I am on nix with netbeans/eclipse/code::blocks. I don't have a problem reading, just looking for a starting point. Any thoughts?

  • dun goofed the files in /usr/lib/x86_64-linux-gnu/

    - by tipu
    there was some weird package issue with (in my limited understanding) 32/64 bit libraries, so i went around making symlinks to the file my lamp installation expected to the ones that actually existed. i did this for a # of files in here: /usr/lib/x86_64-linux-gnu/ however php still ended up not working (separate issue) and now i believe i have a screwed up lib directory. is there a way to revert those library files?

  • Are there software options (preferabbly .NET) for doing distance and speed analysis of footballers moving on video?

    - by Anonymous Type
    Editing Question for Clarity Thanks for feedback so far, very insightful. I'm not sure how far along this part of the software community is, and what if any libraries exist for me to leverage from. Heres what I'm trying to do. Problem: Take an existing video of a game of rugby league. The Rugby League field is 100 metres long, 70 metres wide, and has white line markings every 10 metres running along the width of the field, as well as along the sidelines. Each side has 13 players on the field. Players on each team have identical jerseys that normally constrast strongly against background colours (green/brown field colour) and the referee's colour (usually yellow) and the designated water runner (orange). All players have a unique number in thick white lettering on their backs for identification. Video is taken with a high definition camera. Currently only one camera is used (2D) and existing video does not contain a foreground object of fixed spatial dimensions (as suggested in one answer for comparision measurements, however I could add this to future filming sessions if it is worthwhile). The player's do not run in a straight line 50% of the time but will go sideways on on a diagonal to the play the ball. The distance measured always starts from the spot of the previous "tackle", which ends where the player stops forward movement. It is not always possible to determine the players number from the video (facing other direction, sunlight, others standing in the way of the camera). But this isn't important as the software could allow for manual inputting of unknown "runs" at a later point after analysis. Determine the distance between two points (i.e. where the player started his "run" and where he finished it). I'm guessing that this would be quite doable if I manually marked the start and end point in the video. But how would I use landmarks in the background to determine the distance (assuming the person taking the video has kept it from jerking around). Question: Do software packages or libraries exist that are specialised enough to assist with writing analysis software to determine a sports persons distance travelled based on video taken of the performance?

  • Existent js libs for tileset / map loading and rendering?

    - by ylluminate
    I'm building an rts style overhead tileset game with JavaScript (particularly using Ember.js framework as a base). The map is so large that I'd very much like to be able to load and render the board and layered items in a Google Maps'esque. I'm curious as to whether there are existing libs that would be helpful and already well thought out in these regards vs trying to reinvent the wheel. Are there any such libraries or code examples that would be useful in this area of board / map management?

  • Best jQuery Libraries, Plug-Ins and Controls

    - by schnieds
    Worried About The Loss Of ASP.NET Controls in MVC? Don’t BeIf you are hesitant of moving to ASP.NET MVC because you are worried about losing all of the awesome ASP.NET controls that you are so used to using, don’t be. Wonderful client side controls already exist to replace most, if not all, of the most used ASP.NET controls (and these controls provide a MUCH BETTER user experience.) Here is a list of my favorite jQuery plug-ins and libraries that make user interface development so much easier... [Read More Here]Aaron Schniederhttp://www.churchofficeonline.com

  • What are good JS libraries for game dev?

    - by acidzombie24
    If I decide to write a simple game both text and graphical (2d) what libraries would I use? (Assume we are using a HTML5 compatible browser) The main things I can think of Rendering text on screen Animating sprites (using images/css) Input (capturing the arrow keys and getting relative mouse positions) Perhaps some preloading resource or dynamically loading resources and choosing order Sound (but I am unsure how important this will be to me at first). Perhaps with mixing and chaining sounds or looping forever until stop. Networking (low priority) to connect a user to another or to continuously GET data without multiple request (I know this exist but I don't know how easy it is to setup or use. But this isn't important to me. Its for the question).

  • ASP.NET: Including JavaScript libraries conditionally from CDN

    - by DigiMortal
    When developing cloud applications it is still useful to build them so they can run also on local machine without network connection. One thing you use from CDN when in cloud and from app folder when not connected are common JavaScript libraries. In this posting I will show you how to add support for local and CDN script stores to your ASP.NET MVC web application. Our solution is simple. We will add new configuration setting to our web.config file (including cloud transform file of it) and new property to our web application. In master page where scripts are included we will include scripts from CDN conditionally. There is nothing complex, all changes we make are simple ones. 1. Adding new property to web application Although I am using ASP.NET MVC web application these modifications work also very well with ASP.NET Forms. Open Global.asax and add new static property to your application class. public static bool UseCdn {     get     {         var valueString = ConfigurationManager.AppSettings["useCdn"];         bool useCdn;           bool.TryParse(valueString, out useCdn);         return useCdn;     } } If you want less round-trips to configuration data you can keep some nullable boolean in your application class scope and load CDN setting first time it is asked. 2. Adding new configuration setting to web.config By default my application uses local scripts. Although my application runs on cloud I can do a lot of stuff without staging environment in cloud. So by default I don’t have costs on traffic when including scripts from application folders. <appSettings>   <add key="UseCdn" value="false" /> </appSettings> You can also set UseCdn value to true and change it to false when you are not connected to network. 3. Modifying web.config cloud transform I have special configuration for my solution that I use when deploying my web application to cloud. This configuration is called Cloud and transform for this configuration is located in web.cloud.config. To make application using CDN when deployed to cloud we need the following transform. <appSettings>   <add key="UseCdn"        value="true"        xdt:Transform="SetAttributes"        xdt:Locator="Match(key)" /> </appSettings> Now when you publish your application to cloud it uses CDN by default. 4. Including scripts in master pages The last thing we need to change is our master page. My solution is simple. I check if I have to include scripts from CDN and if it is true then I include scripts from there. Otherwise my scripts will be included from application folder. @if (MyWeb.MvcApplication.UseCdn) {     <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.4.min.js" type="text/javascript"></script> } else {     <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> } Although here is only one script shown you can add all your scripts that are also available in some CDN in this if-else block. You are free to include scripts from different CDN services if you need. Conclusion As we saw it was very easy to modify our application to make it use CDN for JavaScript libraries in cloud and local scripts when run on local machine. We made only small changes to our application code, configuration and master pages to get different script sources supported. Our application is now more independent from external sources when we are working on it.

  • How to find a word within text using XSLT 2.0 and REGEX (which doesn't have \b word boundary)?

    - by Mads Hansen
    I am attempting to scan a string of words and look for the presence of a particular word(case insensitive) in an XSLT 2.0 stylesheet using REGEX. I have a list of words that I wish to iterate over and determine whether or not they exist within a given string. I want to match on a word anywhere within the given text, but I do not want to match within a word (i.e. A search for foo should not match on "food" and a search for bar should not match on "rebar"). XSLT 2.0 REGEX does not have a word boundary(\b), so I need to replicate it as best I can.

  • Is there an easy way to get a list of all successful captures from a regex pre-5.10?

    - by Chas. Owens
    I know the right way to do this if I have Perl 5.10 is to use named captures and values %+, but in Perl 5.8.9 and how can I get a list of successful captures? I have come up with two methods that are both just terrible: #you need to list each possible match my @captures = grep { defined } ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16); and #ew, I turned on symbolic references { no strict 'refs'; my @captures = map { defined $+[$_] ? $$_ : () } 1 .. $#+; } There is a third option I have found involving (?{}), but it requires global variables (because the closure happens at compile time) and takes the regex from reasonably clear to ungodly mess. The only alternative I have found is to capture the whole match and then use another set of regexes to get the values I want (actually I build the first regex out of the other regexes because there is no good reason to duplicate the logic).

  • Better way to write this regex to match multi-ordered property list?

    - by Andrew Philips
    I've been whacking on this regex for a while, trying to build something that can pick out multiple ordered property values (DTSTART, DTEND, SUMMARY) from an .ics file. I have other options (like reading one line at a time and scanning), but wanted to build a single regex that can handle the whole thing. SAMPLE PERL # There has got to be a better way... my $x1 = '(?:^DTSTART[^\:]*:(?<dts>.*?)$)'; my $x2 = '(?:^DTEND[^\:]*:(?<dte>.*?)$)'; my $x3 = '(?:^SUMMARY[^\:]*:(?<dtn>.*?)$)'; my $fmt = "$x1.*$x2.*$x3|$x1.*$x3.*$x2|$x2.*$x1.*$x3|$x2.*$x3.*$x1|$x3.*$x1.*$x2|$x3.*$x2.*$x1"; if ($evts[1] =~ /$fmt/smo) { printf "lines:\n==>\n%s\n==>\n%s\n==>\n%s\n", $+{dts}, $+{dte}, $+{dtn}; } else { print "Failed.\n"; } SAMPLE DATA BEGIN:VEVENT UID:0A5ECBC3-CAFB-4CCE-91E3-247DF6C6652A TRANSP:OPAQUE SUMMARY:Gandalf_flinger1 DTEND:20071127T170005 DTSTART,lang=en_us:20071127T103000 DTSTAMP:20100325T003424Z X-APPLE-EWS-BUSYSTATUS:BUSY SEQUENCE:0 END:VEVENT SAMPLE OUTPUT lines: == 20071127T103000 == 20071127T170005 == Gandalf_flinger1

  • Regular Expressions: RegEx for determining valid PHP class property names?

    - by Brian Lacy
    I am using PHP's magic __set and __get methods to access a private array in a class. I want to make sure the property names requested (i.e. $myObj->FakeProperty) are valid according to PHP property name rules before accessing them. My current RegEx isn't doing the trick; with my test values, _12 always falls through the cracks. I'm not actually sure that my test values even represent a realistic representation of what is and isn't allowed for PHP class property names, but I'm not really too concerned about it, just that I have some sort of rudimentary check in place. Test Fields: albert12 12Albert _12 _Albert12 _12Albert _____a_1 RegEx: ^(?=_*[A-z]+)[A-z0-9_]+$

    I've got a string like... "labour 18909, liberals 12,365,conservatives 14,720" ...and i'd like a regex which can get rid of any thousands separators so i can pull out the numbers easily. Or even a regex which could give me a tidy array like: (labour => 18909, liberals => 12365, conservatives => 14720) Oh i wish i had the time to figure out regexes! Maybe i'll buy one as a toilet book, mmm.

  • In C, how do you capture a group with regex?

    - by Sylvain
    Hi, I'm trying to extract a string from another using regex. I'm using the POSIX regex functions (regcomp, regexec ...), and I fail at capturing a group ... For instance, let the pattern be something as simple as "MAIL FROM:<(.*)>" (with REG_EXTENDED cflags) I want to capture everything between '<' and '' My problem is that regmatch_t gives me the boundaries of the whole pattern (MAIL FROM:<...) instead of just what's between the parenthesis ... What am I missing ? Thanks in advance,

  • Using Scanner in Java how can I hasNext(aString) where the string is not regex pattern?

    - by Parris
    Hi, I am trying to do as my question states, sooo I have the following code which would find the match. String test = scan.next(); if (test.equals("$let")) return 1; However, I would prefer to use hasNext as to not consume a token; however, when i do the following it fails. if (scan.hasNext("$let")) return 1; I realize the when giving has next a variable it expects a pattern, but I thought if i don't have any regex symbols it should work. I also thought $ was possibly some regex symbol so I tried /$ however, that did not work! Thanks for the help!

  • Javascript form validation/sanitizing do i need regex here ?

    - by user318144
    I have a single form input that is for checking domains. Sometimes people type in www. before the domain or .com after the domain name. The service that i use to check availability automatically checks for all top level domains so when people add the .com at the end it becomes redundant. For example the string submitted is domainname.com.com which is clearly invalid. I understand you can do this on the server side but due to some rather weird circumstance i must use javascript for this. So is regex the solution here ? If so is there some kind of regex generator i can use for this or can someone point me in the right direction with a code snippet perhaps ? Appreciate any help thanks!

  • How can I fix this regex to allow a specific string?

    - by Sailing Judo
    This regex comes from Atwood and is used to filter out anchor tags with anything other than the href and a title: <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")?\s?> I need to allow am additional attribute that specifically matches: target="_blank". So the following url should be allowed: <a href="http://www.google.com" target="_blank"> I tried changing the pattern to these: <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")(\starget="_blank")?\s?> <a\shref="(\#\d+|(https?|ftp)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+)"(\stitle="[^"]+")(\starget=\"_blank\")?\s?> Clearly I don't know regex very well. How should the pattern be adjusted to allow the blank target and no other targets?

  • How to check whether a String fully matches a Regex in Scala?

    - by mkneissl
    Assume I have a Regex pattern I want to match many Strings to. val Digit = """\d""".r I just want to check whether a given String fully matches the Regex. What is a good and idiomatic way to do this in Scala? I know that I can pattern match on Regexes, but this is syntactically not very pleasing in this case, because I have no groups to extract: scala> "5" match { case Digit() => true case _ => false } res4: Boolean = true Or I could fall back to the underlying Java pattern: scala> Digit.pattern.matcher("5").matches res6: Boolean = true which is not elegant, either. Is there a better solution?
