47	47
48		-OK, so you want to use Git but you are working on a team project that is hosted in a subversion repository ... and it is making you depressed :-( . Well, you can still use Git to manage your local SVN working copy and be almost happy again (Either way, you won't be 100% happy unless the repository is a git one.)

75	75	This is really an absolute necessity and a **huge** productivity improvement. Basically you need the bash completion script from the source tarball and use your shell profile to include it whenever you open a shell. See the **Auto-Completion** section on this page:

	72	+=== GitX git GUI ===
79	79
80		-SourceTree is a free Git/Mercurial GUI for OS X. A key feature is that it can use git-svn to "Clone" a SVN repository into a standard Git repository with your full SVN commit history and maintains a link back to the SVN repository. This allows you to easily use Git locally for development but still do your final commits to SVN.
	74	+GitX is an awesome FREE history viewer made for OS X. It is a better way to visualize your branch and commit history of your git repository. However, power users (aka "cool kids") will probably only use it for history viewing while they continue to use the terminal command line for checkouts, branching, staging, rebasing and committing.

86		-
87		-While most (if not all) Git GUI apps will never be able to emulate all the intricate functionality of Git, one advantage of a GUI app is more convenient and faster browsing/visualization of history and inter-relationships of branches. While development on the original open source GitX.app has waned, this fork of the original has continued to mature into a nice Git client, and is useful for common every day Git operations. However, power users (aka "cool kids") will probably only use it for history viewing while they continue to use the terminal command line for checkouts, branching, staging, rebasing and committing.

129	129	What if one wants to generate a pull request the origin and also push to a fork? You would do this if you were not a Wonder committer but wanted to share code. You organize your changes in your local repository/branch and, from the clean repository or branch, generate the pull request and, separately, push the changes to your fork.

131		-=== Testing a Pull-Request ===
	116	+=== Versions? or Diffs? ===
132	132
133		-It may not be obvious how to do this. If one is a committer, there is a button one can push to automatically accept a pull-request. But is this really a safe thing to do? But how can you get the diffs being suggested? It seems more complicated than it needs to be to merge the branch the pull-request was made from. One can actually use a URL that specifies just the diff. If the pull-request is at [[https://github.com/projectwonder/wonder/pull/43]], one can do:
	118	+One satori that I had is this. Subversion is all about versions. CVS was all about versions. We have been working with these a long time and the ideas are sticky. Git is //not// about versions. It is about diffs. Diffs are the main thing. If you think about it, this makes sense. You have thoughts and make changes and those diffs are the product of your work. If you get those diffs into something, that is good, but the work product was the diffs.
134	134
135		-{{code}}
136		-curl 'https://github.com/projectwonder/wonder/pull/43.patch' | git am
137		-{{/code}}
	120	+All this rebasing and such may seem odd. But the main thing is the diffs. I have edits from a two-week old repository. What do I do? I move the diffs so that they are diffs from the latest code. That is a rebase. When we make edits, we are used to being over-concerned about merge conflicts. But they do not happen all that often and are actually easy to deal with when they do, if the tools are oriented to making them easy to deal with. If we are worrying about the versions and not the diffs, we are paying attention to the paper we write on and not to the words we are putting down.
138	138
139		-The curl fetches the diff. Take off the "git am" to just see the diffs. The "git am" merges the diffs. Then you may build and test the pull-request. A normal push will push the code into the repository.
	122	+Internally, git keeps track of text fragments and not files. Why is this? Because the versions are not the point. The diffs are. I can imagine how Linus Torvalds had this idea. He was looking at all the versions of all the files in Linux and all the e-mails of all the diffs. These are two separate worlds. It is conceptually painful to look at every diff, find its source and see how it maps to what now exists. At some point, he must have realized that all he needed was the e-mails. If he had no files any longer, but all the e-mails, he could always reconstruct the files. He would not have to make the conceptual switch from the diffs to the versions and back. Collectively, those e-mails with the diffs defined everything that needed to be said. Quod erat demonstrandum.

147	147	Keep in mind that the difficult part of what you do should be the thinking. Git makes it easy to organize and share your thoughts as branches. Your local copies may be messy or not. They are the thoughts you have in your head and lots of those thoughts will stay there and never see the light of day and that is ok. But when you have clarified your thoughts, git will make it easy to share them.

149		-=== Finding the List of All Git Commands ===
150		-
151		-The "git help" command gives one the list of commonly used git commands. How does one find the others, since some of them turn out to be very useful? I tried "git help v". That was wrong. It would have been better to try "git help help", but this did tell me about the -all flag, which actually lists out all of the commands, and there are quite a few of them. So, good hunting.
