Get Visual Studio to run a T4 Template on every build
I agree with GarethJ - in VS2010 it is much easier to regenerate tt templates on each build. Oleg Sych's blog describes how to do it. In short:
- Install Visual Studio SDK
- Install Visual Studio 2010 Modeling and Visualization SDK
- Open in text editor project file and
add to the end of file but before
</Project>
That's it. Open your project. On each build all *.tt templates will be reprocessed
<!-- This line could already present in file. If it is so just skip it -->
<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
<!-- process *.tt templates on each build -->
<PropertyGroup>
<TransformOnBuild>true</TransformOnBuild>
</PropertyGroup>
<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\TextTemplating\v10.0\Microsoft.TextTemplating.targets" />
I used JoelFan's answer to come up w/ this. I like it better because you don't have to remember to modify the pre-build event every time you add a new .tt file to the project.
- add TextTransform.exe to your
%PATH%
- created a batch file named transform_all.bat (see below)
- create a pre-build event "
transform_all ..\..
"
transform_all.bat
@echo off

echo executing transform_all from %wdir%
:: create a list of all the T4 templates in the working dir

echo the following T4 templates will be transformed:
type t4list.txt
:: transform all the templates
for /f %%d in (t4list.txt) do (
set file_name=%%d
set file_name=!file_name:~0,-3!.%extension%
echo: \--^> !file_name!
TextTransform.exe -out !file_name! %%d
)
echo transformation complete
