SVN Basic

subversionA colleague made a pretty cool blog post about svn basic on his blog. Subverion is a software versioning and a revision control system. At work all our program code and scripts, every little piece of code is going in your Subversion repository. This allows you to get back to earlier revisions of the code or simply share and work on code with other employees. Even your documentation is going into the Subversion repository.

On his blog post (German) he shows the basics of subversion, doing a checkout of e repository, adding files, changing files, removing files and more.

Here is a basic list of svn commands, if you need more information you should check the Subversion Homepage or try the Blog post from tspycher.com

svn checkout  http://svn.colab.company.com # SVN checkout
svn commit -m "My Message and Changes" # SVN committing changes and new files
svn add /files/*.* # Adding Files to the SVN Repository after this you have to commit that
svn update # Update your local copy

A lot of IDE’s (Integrated Development Environment) like Visual Studio or Xcode have SVN integrated.

Here is a simple C++ lottery program done for the KTSI.

#include <iostream>
#include <cstdlib>

using namespace std;

int main (int argc, char * const argv[]) {

	int numberCount;
	int maxNumbers;

	cout << "Lottery Game" << endl << "=================================" << endl;
	cout << "How many Lottery Numbers = ";
	cin >> numberCount;
	cout << "from 1 to ? ";
	cin >> maxNumbers;
	cout << "You have chosen " << numberCount << " Lottery Numbers from 1 to " << maxNumbers << endl;

	int lotteryNumbers[numberCount];
	int i, j;
	bool newNumber;

	srand(0);
	for(i=0; i<numberCount; i++) // get numbers
	{
		do
		{   // Check Random
			lotteryNumbers[i] = rand() % maxNumbers + 1;
			newNumber = true;
			for (j=0; j<i; j++)
			{
				if (lotteryNumbers[j]==lotteryNumbers[i])
				{ // Check for existing numbers
					newNumber = false;
				}
			}
		} while (!newNumber);
	}
	for (i=0; i<numberCount; i++)
	{
		cout << lotteryNumbers[i] << " ";
	}
	cout << endl;
}

Powershell: Count your Code lines

Powershell Header

After Coding some lines in a lot of different files you wanna know how much lines you have coded. There are two (I am sure there are even more) ways to do that. The first one is to get the content of the files (Get-Content) and count the lines in there.

The other way and the fasterway is with Select-String:

(Get-ChildItem -Include *.ps1 -Recurse | Select-String -pattern .).Count

Powershell: if Statement basics

Powershell Header

The Iif Statement is a pretty important, if you are creating powershell scripts. So I created this post to get some basic information here.

First the syntax with a simple if:

if (condition) {do}

You can also use elseif and else:

if (condition) {do}
elseif (condition) {do}
else {do}

A simple if could look like this:

if ($varibale -eq "1") {
Write-Host "Yes variable is 1"
}

Comparison Operators:

  • Equal to: -eq
  • Less than: -lt
  • Greater than: -gt
  • Greater than or Eqaul to: -ge
  • Less than or equal to: -le
  • Not equal to: -ne

You can also check case-sensitive by adding a “c” to the operator. “-eq” would be “-ceq”

Logical Operators:

  • Not -not
  • Not !
  • And -and
  • Or -or

So you can simply add multiple conditions:

if ($varibale -eq "1" -or $varibale -eq "2") {
Write-Host "Varibale is 1 or 2"
}
