Conclusion

Git is certainly not an easy tool to learn. Although when you do, it turns into a very powerful and flexible tool.

If you want to learn more about it, please see the excelent book written by Scott Chacon and available for free .

What about you? Have any tips on git you want to share?

Since its release I've been a fan of Git. (I still can remember downloading the initial version.) The thing I like most is that it can be extended and customized in an unixy way. Over time, I have collected some scripts and tricks that I would like to present to a wider audience. Git information online abounds (I especially recommend Mark J. Dominus in-depth posts on Git ), thus I will only show stuff I haven't seen elsewhere.

…framework for hackers. You should be comfortable running shell commands and familiar with the basics of Git. If that sounds daunting, Octopress probably isn't for you.

Now that I had decided on using Octopress, I next needed to figure out where to host it. One of the services I have been hearing a lot about that I have been wanting to play with is Engine Yard, so I thought it would be a good opportunity to try them out as a potential home for my blog. In checking the Octopress documentation, …

Finding this brought to light one of the difficulties, which is that Git diff s won't necessarily show when you exceed 100 lines.

Five lines per method

Limiting methods to five lines per method is the most interesting rule.

We agreed on a fairly strict definition of a line: if , else , and end are all lines. So in an if block with two branches, each branch can only be one line. For example: def validate_actor if actor_type == 'Group' user_must_belong_to_grou …

To solve this problem, I'll be harnessing the power of Git. In a nutshell, we'll have two branches: master and framework . The master branch will be our application. The framework branch will be the Laravel framework that is powering our app. ( Laravel's repository can be found here ) When an update is made to Laravel, we check out the framework branch, pull in the most recent version of the framework, then merge those changes with master . Pretty straightforward. …

These days a lot of people have switched from Subversion to Git. When you've worked with Git for a while, Subversion probably feels archaic and unproductive. The "killer app" for Git is Github , which provides an unbeatable collaboration experience. Indeed, many projects that have switched to Github reported a dramatic increase in contributions!

Git is your friend and you should use it to find data about things from years long gone

Any complicated application, kernel, or whatever will have a large number of ugly scars and warts that cannot be changed to maintain backward compatibility. Such is life.
