• [XSL-FO] Characters from other than English languages

  - by Lukasz Kurylo

  My client have departments in Europe Central and East, so there is highly possibility that in the generated pdfs there will be at least in the people names and/or surnames some specific characters for the country language.   With the XSL-FO we can use some out-of-the box fonts, e.g. the default is Times. We can change it for specific block of text or the entire document to other like Helvetica or Arial. All will be good to the moment that we use only an english alphabet. If we want to add e.g. some characters from polish or bulgarian language, in the *.fo file:         <fo:block >                 <fo:inline font-weight="bold">english: </fo:inline>                 <fo:inline font-weight="bold">yellow</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">polish: </fo:inline>                 <fo:inline font-weight="bold">zólty</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">russian: </fo:inline>                 <fo:inline font-weight="bold">??????</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">bulgarian: </fo:inline>                 <fo:inline font-weight="bold">????</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">english: </fo:inline>                 <fo:inline font-weight="bold">yellow</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">polish: </fo:inline>                 <fo:inline font-weight="bold"  font-family="Arial">zólty</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">russian: </fo:inline>                 <fo:inline font-weight="bold" font-family="Arial">??????</fo:inline>       </fo:block>       <fo:block>                 <fo:inline font-weight="bold">bulgarian: </fo:inline>                 <fo:inline font-weight="bold" font-family="Arial">????</fo:inline>       </fo:block>   The result can be diffrent from the expected depending on the selected font, e.g:                 As you can see Timer nor Arial work in this case.   The problem here is not related to XSL-FO, but rather to the renderer we are using. I have lost a lot of time to find a solution for the using by me XSL-FO –> PDF rendered to acquire these characters in my generated files. Fortunatelly all what have to be done it is to embed the font (or part of it) in the file(s) during rendering.   The renderer that I’m using it is an open source FO.NET.   For this one, the code to generate a pdf file looks that:   var fonet =  Fonet.FonetDriver.Make(); fonet.Render("source.fo", "result.pdf");   To emded the font in the pdf, we need to set the appropriate option to the driver:   fonet.Options = new Fonet.Render.Pdf.PdfRendererOptions() {       FontType = Fonet.Render.Pdf.FontType.Embed }; Right now, the pdf we get should look like this:               As you can see, the result for the Arial font looks exactly how it should, because this font has a characters included not only for the english language like the default Times, which we shouls avoid if we not generating a english-only documents.   This is worth to notice that in this situation the generated pdf file is quite large, it has more than 400 kb in size. This is of course because of embedding the entire font in it to make the document portable to systems, where the used font is not present. Instead on embedding the entire font, we can only embed the subset of used characters by changing the options to:   fonet.Options = new Fonet.Render.Pdf.PdfRendererOptions() {       FontType = Fonet.Render.Pdf.FontType.Subset };   Right now, this specific pdf is only 12 kb in size.

• Mapping Repeating Sequence Groups in BizTalk

  - by Paul Petrov

  Repeating sequence groups can often be seen in real life XML documents. It happens when certain sequence of elements repeats in the instance document. Here’s fairly abstract example of schema definition that contains sequence group: <xs:schemaxmlns:b="http://schemas.microsoft.com/BizTalk/2003"            xmlns:xs="http://www.w3.org/2001/XMLSchema"            xmlns="NS-Schema1"            targetNamespace="NS-Schema1" >  <xs:elementname="RepeatingSequenceGroups">     <xs:complexType>       <xs:sequencemaxOccurs="1"minOccurs="0">         <xs:sequencemaxOccurs="unbounded">           <xs:elementname="A"type="xs:string" />           <xs:elementname="B"type="xs:string" />           <xs:elementname="C"type="xs:string"minOccurs="0" />         </xs:sequence>       </xs:sequence>     </xs:complexType>  </xs:element> </xs:schema> And here’s corresponding XML instance document: <ns0:RepeatingSequenceGroupsxmlns:ns0="NS-Schema1">  <A>A1</A>  <B>B1</B>  <C>C1</C>  <A>A2</A>  <B>B2</B>  <A>A3</A>  <B>B3</B>  <C>C3</C> </ns0:RepeatingSequenceGroups> As you can see elements A, B, and C are children of anonymous xs:sequence element which in turn can be repeated N times. Let’s say we need do simple mapping to the schema with similar structure but with different element names: <ns0:Destinationxmlns:ns0="NS-Schema2">  <Alpha>A1</Alpha>  <Beta>B1</Beta>  <Gamma>C1</Gamma>  <Alpha>A2</Alpha>  <Beta>B2</Beta>  <Gamma>C2</Gamma> </ns0:Destination> The basic map for such typical task would look pretty straightforward: If we test this map without any modification it will produce following result: <ns0:Destinationxmlns:ns0="NS-Schema2">  <Alpha>A1</Alpha>  <Alpha>A2</Alpha>  <Alpha>A3</Alpha>  <Beta>B1</Beta>  <Beta>B2</Beta>  <Beta>B3</Beta>  <Gamma>C1</Gamma>  <Gamma>C3</Gamma> </ns0:Destination> The original order of the elements inside sequence is lost and that’s not what we want. Default behavior of the BizTalk 2009 and 2010 Map Editor is to generate compatible map with older versions that did not have ability to preserve sequence order. To enable this feature simply open map file (*.btm) in text/xml editor and find attribute PreserveSequenceOrder of the root <mapsource> element. Set its value to Yes and re-test the map: <ns0:Destinationxmlns:ns0="NS-Schema2">  <Alpha>A1</Alpha>  <Beta>B1</Beta>  <Gamma>C1</Gamma>  <Alpha>A2</Alpha>  <Beta>B2</Beta>  <Alpha>A3</Alpha>  <Beta>B3</Beta>  <Gamma>C3</Gamma> </ns0:Destination> The result is as expected – all corresponding elements are in the same order as in the source document. Under the hood it is achieved by using one common xsl:for-each statement that pulls all elements in original order (rather than using individual for-each statement per element name in default mode) and xsl:if statements to test current element in the loop:  <xsl:templatematch="/s0:RepeatingSequenceGroups">     <ns0:Destination>       <xsl:for-eachselect="A|B|C">         <xsl:iftest="local-name()='A'">           <Alpha>             <xsl:value-ofselect="./text()" />           </Alpha>         </xsl:if>         <xsl:iftest="local-name()='B'">           <Beta>             <xsl:value-ofselect="./text()" />           </Beta>         </xsl:if>         <xsl:iftest="local-name()='C'">           <Gamma>             <xsl:value-ofselect="./text()" />           </Gamma>         </xsl:if>       </xsl:for-each>     </ns0:Destination>  </xsl:template> BizTalk Map editor became smarter so learn and use this lesser known feature of XSLT 2.0 in your maps and XSL stylesheets.

• mysql does not start or work

  - by Artem Moskalev

  Recently I installed LAMP with tasksel. Then I remember I issued some commands to get into the mysql console - it worked. Right now I checked - apache and php modules work perfectly. But as for mysql - whatever commands I issue - it does not start the console. It writes: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' How can I fix it and start mysql? Why did this happen? Where is it installed (I used the default location for the installation), because I dont understand what is started when I issue the commands?

• Xubuntu 14.04 black screen after monitor off/on

  - by Sampo Smolander

  I have a HP desktop machine with Ubuntu 14.04, with also Xubuntu and Gnome desktops installed. I mostly use the Xubuntu session. When using the Xubuntu session, when I power off my monitor, and power it back on, the screen stays black and I cannot do any work. With ctrl-alt-f6 I can open another virtual terminal, and then the screen works again, but if I to go back to the desktop session with ctrl-alt-f7, all I have is a black screen. But, if I login to Unity (the Ubuntu default session), or to Gnome, and turn the monitor off and back on, everything works ok. Also, if I log out, and while in the lightdm greeter, turn the monitor off and back on, everything works ok. What could be the cause for this, and how to fix this?

• Disable plugin in Firefox (acroread)

  - by cboettig

  I installed acroread from the repositories, and it has decided it should be the default plugin in Firefox, such that when I click on a pdf, it opens in a Firefox window. Unfortunately, it does not display (at least when in dual head mode). This should be simple, but I cannot disable the plugin. Under Firefox Edit - Preferences- Applications - pdf is set to "always ask" so I don't know why it uses acroread in the first place. Under Tools - Manage Content Plugins I see acroread is selected for pdf content. I have the option in the dropdown to search for a new plugin, but not to simply download the file. Typing about:config into the Firefox toolbar gives me a list of configuration options, but does not mention plugin.disable or acroread anywhere. How do I disable the plugin? I have Firefox 11.0 on Ubuntu 11.10

• Can't enable Bluetooth 13.10

  - by user205872

  I'm a new user to Ubuntu. I previously installed Xubuntu 13.04 on my Compaq nx8420 and was able to use Bluetooth with no issues. I recently performed a clean install of Ubuntu 13.10 (not Xubuntu), and now can't enable bluetooth. I go to the default Bluetooth app, move the slider to 'On' and it slides straight back to 'Off'. Do I need to install any extra packages or use an alternative app to get Bluetooth working? I can't think of a reason why it would work in Xubuntu 13.04, but not Ubuntu 13.10. Thanks in advance for any help. Zac

• How to enable rgb colored output in terminal?

  - by t.pimentel

  I'm trying to print a colored string to a gnome-terminal using ANSI escape codes, but, although it works for the custom colors, or even the 256 extra color, it doesn't work with RGB codes. So, simplifying: cout << "\033[33m" << '.' << "\033[0m"; # prints with color cout << "\033[38;5;135m" << '.' << "\033[0m"; # prints with color cout << "\033[38;2;0;135;0m" << '.' << "\033[0m"; # doesn't work, prints with default color How can I output something with an RGB color code in the gnome-terminal? I'm following this link for outputs: Wikipedia ANSI escape code.

• Email links open in a new window [closed]

  - by Dan

  I'm asking this as an opinion question. How does everyone treat email links opening in a new window if their default email client is web based? This way? <a href="mailto:[email protected]">email me</a>. It will open fine for app based email clients but open in the same window for web based clients. This way? <a href="mailto:[email protected]" target="_blank">email me</a>. It will open in a new tab for web based email clients but open a blank tab. I cant really seem to find the best of both worlds. What does everyone else do?

• Stuck while Booting Text Mode in Ubuntu 12.04?

  - by sameetandpotatoes

  I edited the /etc/default/grub file and changed: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” to GRUB_CMDLINE_LINUX_DEFAULT=”text” This does make Ubuntu boot up into text mode; however, it gets stuck while booting up and it does not show me the login text. Instead it says something like this: Begin running /scripts/init-bottom USB hub found ...More irrelevant things... *Stopping LightDM Display Manager I can press Ctrl + Alt + F2 and see the login and boot up like normal, but is there any reason for this? How can I change it so it does not get get stuck? Edit: After 5 minutes, a new line came up: 557.1206341 ieee80211 phy0: channel change: 5540 -> 5560 failed (3).

• How to create a KDE start application menu launcher that launches the search and launch desktop?

  - by davorao

  Now i love the plasma-netbook aka the "search and launch" interface but i would want to be able to have it appear on demand and not sit as the desktop default in the back of my windows. So what i imagine is having a application launcher be created which on activation brings up the "search and launch" feature allowing for easy access of your favorites or have that slick interface to find what your looking for. I'm aware that krunner solves a similar use-case but search and launch would be more of an Unity Dash type of search, whereas krunner is more useful when u exactly know what your looking for. And to summarize my question, since I'm clueless as to how this would be done, I'm lookinf for someone who could tell me how hard it would be to do it.

• How do I resolve this exercise on C++? [closed]

  - by user40630

  (Card Shuffling and Dealing) Create a program to shuffle and deal a deck of cards. The program should consist of class Card, class DeckOfCards and a driver program. Class Card should provide: a) Data members face and suit of type int. b) A constructor that receives two ints representing the face and suit and uses them to initialize the data members. c) Two static arrays of strings representing the faces and suits. d) A toString function that returns the Card as a string in the form “face of suit.” You can use the + operator to concatenate strings. Class DeckOfCards should contain: a) A vector of Cards named deck to store the Cards. b) An integer currentCard representing the next card to deal. c) A default constructor that initializes the Cards in the deck. The constructor should use vector function push_back to add each Card to the end of the vector after the Card is created and initialized. This should be done for each of the 52 Cards in the deck. d) A shuffle function that shuffles the Cards in the deck. The shuffle algorithm should iterate through the vector of Cards. For each Card, randomly select another Card in the deck and swap the two Cards. e) A dealCard function that returns the next Card object from the deck. f) A moreCards function that returns a bool value indicating whether there are more Cards to deal. The driver program should create a DeckOfCards object, shuffle the cards, then deal the 52 cards. This above is the exercise I'm trying to solve. I'd be very much appreciated if someone could solve it and explain it to me. The main idea of the program is quite simple. What I don't get is how to build the constructor for the class DeckOfCards and how to generate the 52 cards of the deck with different suits and faces. Untill now I've managed to do this: #include <iostream> #include <vector> using namespace std; /* * */ /* a) Data members face and suit of type int. b) A constructor that receives two ints representing the face and suit and uses them to initialize the data members. c) Two static arrays of strings representing the faces and suits. d) A toString function that returns the Card as a string in the form “face of suit.” You can use the + operator to concatenate strings. */ class Card { public: Card(int, int); string toString(); private: int suit, face; static string faceNames[13]; static string suitNames[4]; }; string Card::faceNames[13] = {"Ace","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten","Queen","Jack","King"}; string Card::suitNames[4] = {"Diamonds","Clubs","Hearts","Spades"}; string Card::toString() { return faceNames[face]+" of "+suitNames[suit]; } Card::Card(int f, int s) :face(f), suit(s) { } /* Class DeckOfCards should contain: a) A vector of Cards named deck to store the Cards. b) An integer currentCard representing the next card to deal. c) A default constructor that initializes the Cards in the deck. The constructor should use vector function push_back to add each Card to the end of the vector after the Card is created and initialized. This should be done for each of the 52 Cards in the deck. d) A shuffle function that shuffles the Cards in the deck. The shuffle algorithm should iterate through the vector of Cards. For each Card, randomly select another Card in the deck and swap the two Cards. e) A dealCard function that returns the next Card object from the deck. f) A moreCards function that returns a bool value indicating whether there are more Cards to deal. */ class DeckOfCards { public: DeckOfCards(); void shuffleCards(); Card dealCard(); bool moreCards(); private: vector<Card> deck(52); int currentCard; }; int main(int argc, char** argv) { return 0; } DeckOfCards::DeckOfCards() { //I'm stuck here I have no idea of what to take out of here. //I still don't fully get the idea of class inside class and that's turning out as a problem. I try to find a way to set the suits and faces members of the class Card but I can't figure out how. for(int i=0; i<deck.size(); i++) { deck[i]//....There is no function to set them.

• How to use Btrfs with compression on external USB hard drive?

  - by Andre

  I would like to make use of Btrfs' transparent compression on an external drive. Which tool is best for formatting the drive? Disk Utility or GParted? How do I activate the compression? During formatting or when I mount the drive? I guess at mount time. I'm using usbmount to automatically mount newly attached devices, because nobody is logged in on the desktop. Would I have to set general default options somewhere in a system configuration file to get Btrfs mounted with compression, or would I specify this via FS_MOUNTOPTIONS in /etc/usbmount/usbmount.conf and how? Thanks!

• Choppy video in vlc even with hardware acceleration on ATI Radeon HD

  - by l0b0

  After installing Catalyst 11.12 and studying instructions (1, 2) to enable hardware acceleration I ended up with the following command: sudo apt-get install xvba-va-driver libva-glx1 vainfo && \ vainfo && \ vlc --verbose 2 --ffmpeg-hw video.1080p.x264.mkv The output confirms that it's using the VA API: avcodec decoder: Using VA API version 0.32 for hardware decoding. But even after a reboot the video still looks choppy. There's no vlc output to indicate that the codec is having trouble, or that it's skipping frames. Any idea what could be the problem? Using vlc 1.1.12 with default settings. Also tried (in sequence): sudo apt-get install libva-glx1 sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core Rebooting No luck yet.

• When starting or log off/on, add'l panels show and some panel applets are duplicated

  - by keepitsimpleengineer

  After upgrading to 12.04 Gnome Classic amd64,every time I log on a new additional blank panel appears on the top and bottom panels - which I delete every time. In addition, the default panel applets are duplicated in the original panels. Also the panels in the second screen are empty (in addition to the wallpaper being hidden). Update: As suggested by fossfreedomm I created a new user and the same behavior occurred. I increased the height of the panels (2436) and the added panels did not change. If I don't remove the added panels and log off/on I get still another - they accumulate. If I switch user instead of logoff/logon, the add'l panel do not appear.

• UppercuT v1.0 and 1.1&ndash;Linux (Mono), Multi-targeting, SemVer, Nitriq and Obfuscation, oh my!

  - by Robz / Fervent Coder

  Recently UppercuT (UC) quietly released version 1 (in August). I’m pretty happy with where we are, although I think it’s a few months later than I originally planned. I’m glad I held it back, it gave me some more time to think about some things a little more and also the opportunity to receive a patch for running builds with UC on Linux. We also released v1.1 very recently (December). UppercuT v1 Builds On Linux Perhaps the most significant changes to UC going v1 is that it now supports builds on Linux using Mono! This is thanks mostly to Svein Ackenhausen for the patches and working with me on getting it all working while not breaking the windows builds!  This means you can use mono on Windows or Linux. Notice the shell files to execute with Linux that come as part of UC now. Multi-Targeting Perhaps one of the hardest things to do that requires an automated build is multi-targeting. At v1 this is early, and possibly prone to some issues, but available.  We believe in making everything stupid simple, so it’s as simple as adding a comma to the microsoft.framework property. i.e. “net-3.5, net-4.0” to suddenly produce both framework builds. When you build, this is what you get (if you meet each framework’s requirements): At this time you have to let UC override the build location (as it does by default) or this will not work.  Semantic Versioning By now many of you have been using UppercuT for awhile and have watched how we have done versioning. Many of you who use git already know we put the revision hash in the informational/product version as the last octet. At v1, UppercuT has adopted the semantic versioning scheme. What does that mean? This is a short read, but a good one: http://SemVer.org SemVer (Semantic Versioning) is really using versioning what it was meant for. You have three octets. Major.Minor.Patch as in 1.1.0.  UC will use three different versioning concepts, one for the assembly version, one for the file version, and one for the product version. All versions - The first three octects of the version are owned by SemVer. Major.Minor.Patch i.e.: 1.1.0 Assembly Version - The assembly version would much closer follow SemVer. Last digit is always 0. Major.Minor.Patch.0 i.e: 1.1.0.0 File Version - The file version occupies the build number as the last digit. Major.Minor.Patch.Build i.e.: 1.1.0.2650 Product/Informational Version - The last octect of your product/informational version is the source control revision/hash. Major.Minor.Patch.RevisionOrHash i.e. (TFS/SVN): 1.1.0.235 i.e. (Git/HG): 1.1.0.a45ace4346adef0 SemVer is not on by default, the passive versioning scheme is still in effect. Notice that version.use_semanticversioning has been added to the UppercuT.config file (and version.patch in support of the third octet): Gems Support Gems support was added at v1. This will probably be deprecated as some point once there is an announced sunset for Nu v1. Application gems may keep it around since there is no alternative for that yet though (CoApp would be a possible replacement). Nitriq Support Nitriq is a code analysis tool like NDepend. It’s built by Mr. Jon von Gillern. It uses LINQ query language, so you can use a familiar idiom when analyzing your code base. It’s a pretty awesome tool that has a free version for those looking to do code analysis! To use Nitriq with UC, you are going to need the console edition.  To take advantage of Nitriq, you just need to update the location of Nitriq in the config: Then add the nitriq project files at the root of your source. Please refer to the Nitriq documentation on how these are created. UppercuT v1.1 Obfuscation One thing I started looking into was an easy way to obfuscate my code. I came across EazFuscator, which is both free and awesome. Plus the GUI for it is super simple to use. How do you make obfuscation even easier? Make it a convention and a configurable property in the UC config file! And the code gets obfuscated! Closing Definitely get out and look at the new release. It contains lots of chocolaty (sp?) goodness. And remember, the upgrade path is almost as simple as drag and drop!

• All tweak settings not saving after last 2 updates?

  - by mawburn

  I am running Ubuntu GNOME 14.04. After the last 2 updates, all settings in the Tweak menu are no saving. It will also not switch to the Gnome Dark theme at all. This includes all Startup Application changes as well as any changes to Extension settings. I'm not sure if I need to include any sort of log records or anything like that, so if you need any more information please ask. I've noticed the default fonts seem to be different. I don't remember that being part of the theme settings. It's almost like I'm running in Safe Mode.

• Backup systems config files

  - by David ???

  I'm planning on installing nVidia proprietary drivers on my Ubuntu 10.10. Historically this always ends-up with me being left with no graphical interface. No ability to revert - and reinstalling the whole system. So now, before trying this anew, I wish to backup all relevant config files. I'll try 1 or 2 methods. I'll list each one's commands. I'll appreciate if anyone can tell me how to backup the relevant file, or what's the reverse of this operation. 10x, David Method I - as described here: apt-get --purge remove xserver-xorg-video-nouveau As described in this answer: edit /etc/default/grub and add the line GRUB_CMDLINE_LINUX="nouveau.modeset=0" sudo update-grub Reboot Install original drivers downloaded from nVidia site. Method II - as described here: sudo apt-get purge nvidia* [possibly 'sudo gedit /etc/modprobe.d/blacklist.conf' adding 'vga16fb' 'nouveau' sudo apt-get install nvidia-glx-185 sudo modprobe nvidia sudo lsmod | grep -i nvidia sudo nvidia-xconfig

• Ubuntu on a USB

  - by Sander de Lange

  I was just wondering if anyone had a good experience with Ubuntu on a flash drive... I'm installing it right now. I formatted my 16GB flash drive to Ext2 because the default file system is ext4 but that one is journaled and USB flash drives do not like journaling. I want to use this to learn Java and Ubuntu seems to be a great OS for this. I (obviously) have USB 2.0 ports where I will put the USB in. How is the boot time of Ubuntu on a USB?

• Team Foundation Server (TFS) Team Build Custom Activity C# Code for Assembly Stamping

  - by Bob Hardister

  For the full context and guidance on how to develop and implement a custom activity in Team Build see the Microsoft Visual Studio Rangers Team Foundation Build Customization Guide V.1 at http://vsarbuildguide.codeplex.com/ There are many ways to stamp or set the version number of your assemblies. This approach is based on the build number.   namespace CustomActivities { using System; using System.Activities; using System.IO; using System.Text.RegularExpressions; using Microsoft.TeamFoundation.Build.Client; [BuildActivity(HostEnvironmentOption.Agent)] public sealed class VersionAssemblies : CodeActivity { /// <summary> /// AssemblyInfoFileMask /// </summary> [RequiredArgument] public InArgument<string> AssemblyInfoFileMask { get; set; } /// <summary> /// SourcesDirectory /// </summary> [RequiredArgument] public InArgument<string> SourcesDirectory { get; set; } /// <summary> /// BuildNumber /// </summary> [RequiredArgument] public InArgument<string> BuildNumber { get; set; } /// <summary> /// BuildDirectory /// </summary> [RequiredArgument] public InArgument<string> BuildDirectory { get; set; } /// <summary> /// Publishes field values to the build report /// </summary> public OutArgument<string> DiagnosticTextOut { get; set; } // If your activity returns a value, derive from CodeActivity<TResult> and return the value from the Execute method. protected override void Execute(CodeActivityContext context) { // Obtain the runtime value of the input arguments string sourcesDirectory = context.GetValue(this.SourcesDirectory); string assemblyInfoFileMask = context.GetValue(this.AssemblyInfoFileMask); string buildNumber = context.GetValue(this.BuildNumber); string buildDirectory = context.GetValue(this.BuildDirectory); // ** Determine the version number values ** // Note: the format used here is: major.secondary.maintenance.build // ----------------------------------------------------------------- // Obtain the build definition name int nameStart = buildDirectory.LastIndexOf(@"\") + 1; string buildDefinitionName = buildDirectory.Substring(nameStart); // Set the primary.secondary.maintenance values // NOTE: these are hard coded in this example, but could be sourced from a file or parsed from a build definition name that includes them string p = "1"; string s = "5"; string m = "2"; // Initialize the build number string b; string na = "0"; // used for Assembly and Product Version instead of build number (see versioning best practices: **TBD reference) // Set qualifying product version information string productInfo = "RC2"; // Obtain the build increment number from the build number // NOTE: this code assumes the default build definition name format int buildIncrementNumberDelimterIndex = buildNumber.LastIndexOf("."); b = buildNumber.Substring(buildIncrementNumberDelimterIndex + 1); // Convert version to integer values int pVer = Convert.ToInt16(p); int sVer = Convert.ToInt16(s); int mVer = Convert.ToInt16(m); int bNum = Convert.ToInt16(b); int naNum = Convert.ToInt16(na); // ** Get all AssemblyInfo files and stamp them ** // Note: the mapping of AssemblyInfo.cs attributes to assembly display properties are as follows: // - AssemblyVersion = Assembly Version - used for the assembly version (does not change unless p, s or m values are changed) // - AssemblyFileVersion = File Version - used for the file version (changes with every build) // - AssemblyInformationalVersion = Product Version - used for the product version (can include additional version information) // ------------------------------------------------------------------------------------------------------------------------------------------------ Version assemblyVersion = new Version(pVer, sVer, mVer, naNum);

// Enumerate over the assemblyInfo version attributes foreach (string attribute in new[] { "AssemblyVersion", "AssemblyFileVersion", "AssemblyInformationalVersion" }) { // Define the regular expression to find in each and every Assemblyinfo.cs files (which is for example 'AssemblyVersion("1.0.0.0")' ) Regex regex = new Regex(attribute + @"\(""\d+\.\d+\.\d+\.\d+""\)"); foreach (string file in Directory.EnumerateFiles(sourcesDirectory, assemblyInfoFileMask, SearchOption.AllDirectories)) { string text = File.ReadAllText(file); // Read the text from the AssemblyInfo file // If the AsemblyInformationalVersion attribute is not in the file, add it as the last line of the file // Note: by default the AssemblyInfo.cs files will not contain the AssemblyInformationalVersion attribute if (!text.Contains("[assembly: AssemblyInformationalVersion(\"")) { string lastLine = Environment.NewLine + "[assembly: AssemblyInformationalVersion(\"1.0.0.0\")]";

• New vs Clone Git in Eclipse with EGit

  - by Matty F

  I'm not sure I have either my new repo or clone repo workflow, or both, setup correctly. When I create a new project I create a repo on github, can't clone from it as it's empty so I create a new project which goes into my workspace and then the git init runs on the workspace copy. So I end up with everything in workspace\project-name. However, when I clone from github first I need to clone the repo and this goes into my default git directory (C:\git) as git\cloned-project-name, I then need to import this Git repo as a project into my workspace and I end up with workspace\cloned-project-name effectively duplicating the project folder in the git area. I've tried to clone to workspace\cloned-project-name but then it asks to import the git project and if I try to use workspace\cloned-project-name again, it errs. What am I doing wrong? Thanks, Matt.
