[stringtemplate-interest] Problem with upgrading to ST4 in c#

[Sam Harwell]

Hi Jakub,

ST4 requires template files to include a template declaration. I modified the test template you sent me to be compatible with ST4 (see attached).

The new syntax allows you to specify formal arguments for templates where it wasn't possible before.

Thanks,
Sam

Hi,

attached file attached file contains VS2010 project with demo of this problem. Just copy ST4# binaries to the lib folder and watch console for error message.

The body of the template is trivial 4 characters "ABCD".

Thanks
Jakub
