HeatFile Task

The HeatFile task wraps heat.exe, the WiX harvester, using the file harvesting type. Authoring is generated for type libraries and self-registration from DllRegisterServer. It supports a variety of settings that are described in more detail below. To control these settings in your .wixproj file, you can create a PropertyGroup and specify the settings that you want to use for your build process. The following is a sample PropertyGroup that contains settings that will be used by the HeatFile task:

<HeatFile
  NoLogo="$(HarvestFileNoLogo)"
  SuppressAllWarnings="$(HarvestFileSuppressAllWarnings)"
  SuppressSpecificWarnings="$(HarvestFileSuppressSpecificWarnings)"
  ToolPath="$(WixToolPath)"
  TreatWarningsAsErrors="$(HarvestFileTreatWarningsAsErrors)"
  TreatSpecificWarningsAsErrors="$(HarvestFileTreatSpecificWarningsAsErrors)"
  VerboseOutput="$(HarvestFileVerboseOutput)"
  AutogenerateGuids="$(HarvestFileAutogenerateGuids)"
  GenerateGuidsNow="$(HarvestFileGenerateGuidsNow)"
  OutputFile="$(IntermediateOutputPath)_%(HarvestFile.Filename)_file.wxs"
  SuppressFragments="$(HarvestFileSuppressFragments)"
  SuppressUniqueIds="$(HarvestFileSuppressUniqueIds)"
  Transforms="%(HarvestFile.Transforms)"
  File="@(HarvestFile)"
  ComponentGroupName="%(HarvestFile.ComponentGroupName)"
  DirectoryRefId="%(HarvestFile.DirectoryRefId)"
  PreprocessorVariable="%(HarvestFile.PreprocessorVariable)"
  SuppressCom="%(HarvestFile.SuppressCom)"
  SuppressRegistry="%(HarvestFile.SuppressRegistry)"
  SuppressRootDirectory="%(HarvestFile.SuppressRootDirectory)" />

The following table describes the common WiX MSBuild parameters that are applicable to the HeatFile task.

Parameter Description
NoLogo Optional boolean parameter.

Specifies that the tool logo should be suppressed. The default is false. This is equivalent to the -nologo switch.
SuppressAllWarnings Optional boolean parameter.

Specifies that all warnings should be suppressed. The default is false. This is equivalent to the -sw switch.
SuppressSpecificWarnings Optional string parameter.

Specifies that certain warnings should be suppressed. This is equivalent to the -sw[N] switch.
TreatSpecificWarningsAsErrors Optional string parameter.

Specifies that certain warnings should be treated as errors. This is equivalent to the -wx[N] switch.
TreatWarningsAsErrors Optional boolean parameter.

Specifies that all warnings should be treated as errors. The default is false. This is equivalent to the -wx switch.
VerboseOutput Optional boolean parameter.

Specifies that the tool should provide verbose output. The default is false. This is equivalent to the -v switch.

 

The following table describes the parameters that are common to all heat tasks that are applicable to the HeatFile task.

Parameter Description
AutogenerateGuids Optional boolean parameter.

Whether to generate authoring that relies on auto-generation of component GUIDs. The default is $(HarvestAutogenerateGuids) if specified; otherwise, true.
GenerateGuidsNow Optional boolean parameter.

Whether to generate authoring that generates durable GUIDs when harvesting. The default is $(HarvestGenerateGuidsNow) if specified; otherwise, false.
OutputFile Required item parameter.

Specifies the output file that contains the generated authoring.
SuppressFragments Optional boolean parameter.

Whether to suppress generation of separate fragments when harvesting. The default is $(HarvestSuppressFragments) if specified; otherwise, true.
SuppressUniqueIds Optional boolean parameter.

Whether to suppress generation of unique component IDs. The default is $(HarvestSuppressUniqueIds) if specified; otherwise, false.
Transforms Optional string parameter.

XSL transforms to apply to all generated WiX authoring. Separate multiple transforms with semicolons. The default is $(HarvestTransforms) if specified.

 

The following table describes the parameters that are specific to the HeatFile task.

Parameter Description
File Required item group parameter.

The list of files to harvest.
ComponentGroupName Optional string parameter.

The name of the ComponentGroup to create for all the generated authoring.
DirectoryRefId Optional string parameter.

The ID of the directory to reference instead of TARGETDIR.
PreprocessorVariable Optional string parameter.

Substitute SourceDir for another variable name (ex: var.Dir).
SuppressCom Optional boolean parameter.

Suppress generation of COM registry elements. The default is false.
SuppressRegistry Optional boolean parameter.

Suppress generation of a Directory element for the parent directory of the file. The default is false.
SuppressRootDirectory Optional boolean parameter.

Suppress generation of any registry elements. The default is false.
