#summary Home page for Google Ctemplate
= Google Ctemplate =
A simple but powerful template language for C++.
== Overview ==
The ctemplate package contains a library implementing 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.
Ctemplate is distributed under the terms of the
[http://www.opensource.org/licenses/bsd-license.php BSD License].
To learn more about how to use ctemplate, see the
[http://google-ctemplate.googlecode.com/svn/trunk/docs/index.html Documentation].

== Example ==
This is by no means a complete example; it simply gives you a 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 = random() % 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;
}
}}}
