Welcome to the Google C++ template system! As a quick start, here's a
|
|
small but complete program that uses this template library. For more
|
|
details see, the links below.
|
|
|
|
<h3>Template file <code>example.tpl</code></h3>
|
|
<pre>
|
|
Hello {{NAME}},
|
|
You have just won ${{VALUE}}!
|
|
{{#IN_CA}}Well, ${{TAXED_VALUE}}, after taxes.{{/IN_CA}}
|
|
</pre>
|
|
|
|
<h3>C++ program <code>example.cc</code></h3>
|
|
<pre>
|
|
#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;
|
|
}
|
|
</pre>
|
|
|
|
<h3>Compiling and linking (using gcc)</h3>
|
|
<pre>
|
|
gcc -o example example.cc -lctemplate_nothreads
|
|
</pre>
|
|
|
|
<p>I can use the "nothreads" library because <code>example.cc</code>
|
|
doesn't use threads. If <code>example.cc</code> were threaded, I
|
|
would do something like this instead:</p>
|
|
<pre>
|
|
gcc -o example example.cc -lctemplate -pthread
|
|
</pre>
|
|
|
|
<p>See the README for more details about the two different ctemplate
|
|
libraries.</p>
