This targets file is for defining custom build tools used to process special input
files, typically producing source files for further processing. Just following the
model of the existing examples below to add a new one.

<Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <PropertyGroup>
    <SingularityCustomBuildToolsIncluded>true</SingularityCustomBuildToolsIncluded>
  </PropertyGroup>

  <Target Name="RunCustomBuildTools"
          DependsOnTargets="CreateLanguageCompileItems;
                            CreateCsUnionCompileItems;
                            "/>

  <!--
  This target allows projects to include language files (.lang), which are processed by the SPG tool.
  Each .lang input file creates a single output file (source code), and that output file is added
  to the list of source files to compile into the assembly.  To use this, add 'LanguageFile' items
  to your project.  You must provide Namespace and ClassName metadata for each LanguageFile item.
  For example:

      <ItemGroup>
        <LanguageFile Include="script.lang">
          <ClassName>ScriptParser</ClassName>
          <Namespace>Microsoft.Singularity.Applications</Namespace>
        </LanguageFile>
      </ItemGroup>

  -->
  <Target Name="BuildLanguageFiles"
          Inputs="%(LanguageFile.Identity)"
          Outputs="$(OutputPath)\%(LanguageFile.filename)_language.sg">
    <Error Condition="'%(LanguageFile.Identity)'!='' and '%(LanguageFile.Namespace)'==''" Text="All LanguageFile items require that the Namespace metadata be provided."/>
    <Error Condition="'%(LanguageFile.Identity)'!='' and '%(LanguageFile.ClassName)'==''" Text="All LanguageFile items require that the ClassName metadata be provided."/>

    <Message Text="Building languages"/>
    <MakeDir Directories="$(OutputPath)"/>
    <Exec Command="&quot;$(BUILDDIR)\spg&quot; &quot;%(LanguageFile.Identity)&quot; %(LanguageFile.Namespace) %(LanguageFile.ClassName) &quot;$(OutputPath)\%(LanguageFile.filename)_language.sg&quot;"/>
  </Target>

  <!-- Generate 'Compile' items so that the BuildAssembly target will include the output of this target. -->
  <Target Name="CreateLanguageCompileItems" DependsOnTargets="BuildLanguageFiles">
    <CreateItem Include="@(LanguageFile->'$(OutputPath)\%(filename)_language.sg')">
      <Output TaskParameter="Include" ItemName="Compile"/>
    </CreateItem>
  </Target>

  <!--
  This target allows you to generate C# classes for disjoint unions, similar to ML datatypes. See
  the mkunion documentation for details. It runs csunion files (.csunion) through the mkunion tool.
  Each .csunion input file creates a single .cs output file (source code), and that output file is added
  to the list of source files to compile into the assembly.  To use this, add 'CsUnionFile' items
  to your project.  You must provide Namespace metadata for each CsUnionFile item.
  For example:

      <ItemGroup>
        <CsUnionFile Include="MyUnions.csunion">
          <Namespace>Microsoft.Singularity.Applications</Namespace>
        </CsUnionFile>
      </ItemGroup>

  -->
  <Target Name="BuildCsUnionFiles"
          Inputs="%(CsUnionFile.identity)"
          Outputs="$(OutputPath)\%(CsUnionFile.filename)_csunion.cs">
    <Error Condition="'%(CsUnionFile.identity)'!='' and '%(CsUnionFile.Namespace)'==''" Text="All CsUnionFile items require that the Namespace metadata be provided."/>

    <Message Text="Building CsUnion files"/>
    <MakeDir Directories="$(OutputPath)"/>
    <Exec Command="&quot;$(BUILDDIR)\mkunion&quot; &quot;%(CsUnionFile.Identity)&quot; %(CsUnionFile.Namespace) &quot;$(OutputPath)\%(CsUnionFile.filename)_csunion.cs&quot;"/>
  </Target>

  <!-- Generate 'Compile' items so that the BuildAssembly target will include the output of this target. -->
  <Target Name="CreateCsUnionCompileItems" DependsOnTargets="BuildCsUnionFiles">
    <CreateItem Include="@(CsUnionFile->'$(OutputPath)\%(filename)_csunion.cs')">
      <Output TaskParameter="Include" ItemName="Compile"/>
    </CreateItem>
  </Target>
