Renaming files

Lately I tried to order a bunch of my old photos. All imported from CD, with similar names (guess it was from back when the digicams started over once they'd lost their battery?).

Any huh I needed to rename some photos when there was a name clash, and I didn't bother pointing and clicking in this case. Here's a small command line renamer:

for i in *.jpg ; do mv $i new_name${i#01} ; done

Have fun!

UnitTest++

Writing unit tests for your C++ code is sometimes painful. But fear no more, with UnitTest++ and it's fixture feature, your shared data between the individual tests becomes so easy to set up it's almost cheating! Sweet!

jUnit test reporter available for unittest++ 1.4 - docs.google.com/folder/d/0B_6N…

The code in the tweet is for the svn version of the unittest++ framework, not the one available in google code!!

Just dump the files in your test directory and use them like this:

#include <fstream>
#include <unittest++/UnitTest++.h>
#include <unittest++/TestRunner.h>
#include <test_reporter_junit.h>

using namespace std;
using namespace UnitTest;

int main()
{
    ofstream f("test-report.xml");
    Test_reporter_junit reporter(f);
    TestRunner runner(reporter);
    return runner.RunTestsIf(Test::GetTestList(),NULL,True(),0);
}
