Using T4 I want to generate some code based on examining what files are

Using T4 I want to generate some code based on examining what files are in a directory relative to the template file being executed.

Is there a way in c# to identify what the path of the current template file is?

    • You need to set the hostspecific="true" property of the <#@ template directive to True.
    • This will make T4 generate a special property called Host, which gives you access to ResolvePath method and TemplateFile property.
      • Host is of type ITextTemplatingEngineHost.
      • TemplateFile is a String value which is typically the file-system path of the .tt file – however other T4 hosts (i.e. hosts other than Visual Studio) which may load a T4 file in-memory or otherwise may return some other value as the template file doesn’t exist on-disk.
    • You can find details here: http://www.olegsych.com/2008/02/t4-template-directive/

    For example:

    <#@ template hostspecific="true" #> <#@ import namespace="System.IO" #> <#@ import namespace="Microsoft.VisualStudio.TextTemplating" #> <#     ITextTemplatingEngineHost t4Host = this.Host;     FileInfo t4FileInfo = new FileInfo( t4Host.TemplateFile ); #>  // This file generated by <#= t4FileInfo.FullName #>
