CTemplate is a simple but powerful template language for C++. It emphasizes separating logic from presentation: it is impossible to embed application logic in this template language.

Here's an example of how to use it: not complete, but gives a good feel for what the ctemplate API looks like.

Here is a simple template file:

Hello {{NAME}},
You have just won ${{VALUE}}!
{{#IN_CA}}Well, ${{TAXED_VALUE}}, after taxes.{{/IN_CA}}

Here is a C++ program to fill in the template, which we assume is stored in the file 'example.tpl':

#include <stdlib.h>
#include <string>
#include <iostream>  
#include <google/template.h>  
int main(int argc, char** argv) {
  google::TemplateDictionary dict("example");
  dict.SetValue("NAME", "John Smith");
  int winnings = rand() % 100000;
  dict.SetIntValue("VALUE", winnings);
  dict.SetFormattedValue("TAXED_VALUE", "%.2f", winnings * 0.83);
  // For now, assume everyone lives in CA.
  // (Try running the program with a 0 here instead!)
  if (1) {
    dict.ShowSection("IN_CA");
  }
  google::Template* tpl = google::Template::GetTemplate("example.tpl",
                                                        google::DO_NOT_STRIP);
  std::string output;
  tpl->Expand(&output, &dict);
  std::cout << output;
  return 0;
}

If you are interested in this templating language but are programming in Java, consider Hapax, which is similar to ctemplate.
