Video: Viewing stashed changes

In last movie, we saw how to make an edit and then to put it into the stash. In this movie, we're going to see how we can view those changes in the stash. Once again, we're going to use the git stash command, that's going to be true for all of the things that have to do with the stash, git stash followed by something else. Before we did git stash save, this time we're going to do git stash list, and that's going to show us a list of the things that are in the stash. So here, there's one item in the stash, it's this line right here, stash @ sign, curly braces, 0.

Git Essential Training
6h 26m Beginner Aug 24, 2012

Viewers: in countries Watching now:

The course shows how to use Git, the popular open-source version control software, to manage changes to source code and text files. Using a step-by-step approach, author Kevin Skoglund presents the commands that enable efficient code management and reveals the fundamental concepts behind version control systems and the Git architecture. Discover how to track changes to files in a repository, review previous edits, and compare versions of a file; create branches to test new ideas without altering the main project; and merge those changes into the project if they work out. The course begins by demonstrating version control in a single-user, standalone context, before exploring how remote repositories allow users to collaborate on projects effectively.

Topics include:
  • Exploring the history of version control
  • Installing Git on Mac, Windows, and Linux
  • Initializing a repository
  • Writing useful commit messages
  • Understanding the Git three-tree architecture
  • Tracking when files are added, edited, deleted, or moved
  • Viewing change sets and comparing versions
  • Undoing changes and rolling back to previous versions
  • Ignoring changes to select files
  • Creating and working with code branches
  • Merging branches and resolving merge conflicts
  • Stashing changes for later
  • Working with hosted repositories and remote branches
  • Developing an effective collaboration workflow

Viewing stashed changes

In last movie, we saw how to make an edit and then to put it into the stash. In this movie, we're going to see how we can view those changes in the stash. Once again, we're going to use the git stash command, that's going to be true for all of the things that have to do with the stash, git stash followed by something else. Before we did git stash save, this time we're going to do git stash list, and that's going to show us a list of the things that are in the stash. So here, there's one item in the stash, it's this line right here, stash @ sign, curly braces, 0.

This is the way to refer to this item in the stash. Let's remember that, that's the syntax, stash @ sign, curly braces followed by a number. The number here is going to be 0, next one will be 1, then 2, then 3, then 4 and so on, so there're all going to be numbered. Next it tells us on shorten_title, that's the branch that I was on, when I put it in the stash because the stash is going to be accessible even when I switch branches. So if I switch to my master branch, let's try that real quick, git checkout master, and then I do git stash list.

It's still there. The stash is available all the time. I can always pull from it. That makes it really handy, especially if you start to make a change on one branch, and then you realize this isn't the branch that you wanted to commit those changes to, you can put them in the stash, change your branches and then pull them back out of the stash again. Back to the listing, it tells us what branch we were on, when we first made the stash, and then it gives the description that we gave to it, so we'd know what where we stashing. Now we can see more information about each of those stashes by saying, git stash show, and then this name right here.

Now it's a bit awkward to type the name, I know it is. It's stash, @ sign, curly braces, zero, curly braces. That's how we refer to it. And it comes up and by default it shows us what's called diff stat. This is a stat about what changed in this file. So that's by default. If we want to see more information, we really want to use the -p option, which is show it to us as a patch. A patch is a section of code that you can apply to different things to modify them and change them. So this is basically saying, show us the edits.

The -p option, I'm going to clear the screen before I do it, and what we see is the typical diff that we're used to showing us the sets of changes. This is very similar to showing a commit. So now that we know how to put things into the stash, we know how to look at the stash and see what's in there. Next thing is to be able to pull items out of the stash, and we'll do that in the next movie.

Q: In the Chapter 10 movie "Configuring the command prompt to show the branch," when I type the function "__git_ps1," I do not get the expected result.
A: The function "__git_ps1" was recently moved to a new file, .git-prompt.sh, as described here: https://github.com/git/git/commit/af31a456b4cd38f2630ed8e556e23954f806a3cc.

We will update the video. In the meantime, you may do the same steps you do for .git-completion.bash, but a second time using ".git-prompt.sh" as shown here: https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh.
Q: When I use the code the instructor advises in the above video ("git config
--global user.name "Nelda Street"), I still get an "Illegal Instruction"
error. I have OS 10.6.8. Am I doing something wrong?
A: The current installer version of git isn't compatible with older Mac OS versions.
 
https://code.google.com/p/git-osx-installer/issues/detail?id=96
 
The workaround solutions people offer are:
 
1. To add "-mmacosx-version-min=10.6" as described here:
https://stackoverflow.com/questions/14268887/what-is-the-illegal-instruction-4-error-and-why-does-mmacosx-version-min-10
 
https://stackoverflow.com/questions/10177038/illegal-instruction-4-shows-up-in-os-x-lion
 
2. Or to use the version of git that comes with Xcode, or to use homebrew to install git instead.
