Building MSI files from NAnt and Updating the VDProj's version information and other sins on Tuesday

So, I commited a series of mortal sins today, but hey, it works, right? :)  Other people have felt my pain, so I thought I'd share.

We have a glorious automated build process with NAnt and NUnit and CruiseControl.  We also update all the AssemblyInfo files (we actually create 'AssemblyVersion.cs' files).  We zip up all the binaries and NDoc generated CHM files.

Additionally I want to create an MSI file at the end of it all. 

Given:

  • I don't want to mess with Installshield yet as the VS.NET stuff does what I need for now. 
  • I don't want to mess with the msitask because it's too freaky.

Therefore:

  • I update the versions inside of the setup.vdproj myself with some of the worse regex's and crappiest code I've done in the last month.

    <target name="updatemsisetupversion" depends="setup">
    <property name="short.project.version" value="0.0.0" />
    <script language="C#">
    <code>CDATA[
    public static void ScriptMain
    (Project project) {
    //Shorten the project string
    (like 1.3.4.5, to 1.3.4)
    string projectVersion = project.Properties["project.version"];
    projectVersion = projectVersion.Substring(0,projectVersion.LastIndexOf("."));
    project.Properties["short.project.version"] = projectVersion;
    string setupFileName = Path.Combine(project.BaseDirectory, "setup\\MySetup.vdproj");
    StreamReader reader = File.OpenText(setupFileName);
    string file = String.Empty;
    try {
    Regex expression1 = new Regex(@"(?:\""ProductName\"" = \""8.My Project  )(\d.\d.\d+)");
    Regex expression2 = new Regex(@"(?:\""ProductCode\"" = \""8.){([\d\w-]+)}");
    Regex expression3 = new Regex(@"(?:\""PackageCode\"" = \""8.){([\d\w-]+)}");
    Regex expression4 = new Regex(@"(?:\""ProductVersion\"" = \""8.)(\d.\d.\d+)");
    file = reader.ReadToEnd();
    file = expression1.Replace(file,"\"ProductName\" = \"8:My Project " + projectVersion);
    file = expression2.Replace(file,"\"ProductCode\" = \"8:{" + Guid.NewGuid().ToString().ToUpper() + "}");
    file = expression3.Replace(file,"\"PackageCode\" = \"8:{" + Guid.NewGuid().ToString().ToUpper() + "}");
    file = expression4.Replace(file,"\"ProductVersion\" = \"8:" + projectVersion);
    }
    finally {
    //
    must remember to close the file or the compile may not work
    reader.Close();
    }
    //
    create a writer and open the file
    TextWriter tw = new StreamWriter(setupFileName);
    try {
    // write a line of text to the file
    tw.WriteLine(file);
    }
    finally {
    //
    close the stream
    tw.Close();
    }
    }
    ]]>code>

  • Then, I shell out devenv.exe and run my new vdproj with

Note: YES, I know the RegEx's suck, and I'm loading the file into a single string, and blah blah blah, micro perf, optimizations, etc.  But, it's a build file. so Nyah! :P
