Other languages:

To include source code within the wiki, we are using the extension SyntaxHighlight_GeSHi. You can easily include a code snippet using the tag <syntaxhighlight> </syntaxhighlight>.

Options of the <syntaxhighlight> tag

For a complete list of options, please refer to this page.

lang option

The lang option defines the language used for syntax highlighting. The default language, if this option is omitted, is C++. The complete list of supported languages is available here.

line option

The line option displays line numbers.

Example

Here is an example of a C++ code snippet created with the <syntaxhighlight lang="cpp" line> ... </syntaxhighlight> tag.

#include <iostream>
#include <fstream>
#include <unistd.h>
#include <sstream>
using namespace std;

void flushIfBig(ofstream & out, ostringstream & oss, int size, bool force=false) {
	if (oss.tellp() >= size) {
		out << oss.str();
		oss.str(""); //reset buffer
	}
}
int main() {
	int buff_size = 50*1024*1024;

ofstream out ("file.dat");
	ostringstream oss (ostringstream::app);
	oss.precision(5);
	for (int i=0; i<100*buff_size; i++)
	{
		oss << i << endl;
		flushIfBig(out,oss,buff_size);
	}
	flushIfBig(out,oss,buff_size,true);
	out.close();
}
