It’s never to late for git.

If not already done, every software developer must try GIT – the fast, distributed version control system. It’s such a nice and useful tool. Once every week I find a new little nice feature.

The last month I used the git-client together with a svn-remote repository and I will never use the svn client again. It is so handy to have the full history of the repository on my notebook.  I can commit my changes every time to my local repository and merging/branching is just fun.  I’m so much faster …

Here my path to git

Here my favorite git client in action (the command line client 😉 :

git command line

There are plugins for eclise, idea, windows, mac… So give it a try and have fun!

And if you want to have the little nice prompt add the following lines to your .bashrc:

...
#-----------------------------------
# git in prompt
#-----------------------------------
        RED="\[\033[0;31m\]"
     YELLOW="\[\033[0;33m\]"
      GREEN="\[\033[0;32m\]"
       BLUE="\[\033[0;34m\]"
  LIGHT_RED="\[\033[1;31m\]"
LIGHT_GREEN="\[\033[1;32m\]"
      WHITE="\[\033[1;37m\]"
 LIGHT_GRAY="\[\033[0;37m\]"
 COLOR_NONE="\[\e[0m\]"

        branch_pattern="^# On branch ([^${IFS}]*)"
        remote_pattern="# Your branch is (.*) of"

        if [[ ! ${git_status} =~ "working directory clean" ]]; then
                state="${RED}?"
        else
                state="${GREEN}?"
        fi
 
        # add an else if or two here if you want to get more specific
        if [[ ${git_status} =~ ${remote_pattern} ]]; then
                if [[ ${BASH_REMATCH[1]} == "ahead" ]]; then
                        remote="${YELLOW}?"
                else

I found this script at github and changed it a little bit. Thx to trapni.
