git switches branches without local code

With the continuous development of software development, version control has become an indispensable tool for every developer. Git, as the most popular version control tool at present, occupies an increasingly important position. In Git, branching is a very important concept, which allows developers to perform multiple different development tasks at the same time. However, when switching branches, we often need to pay attention to some issues. For example, when switching branches, we should submit the code of the current branch to the remote warehouse. But in some cases, we do not want to submit the code of the current branch, but only Want to switch branches. So, how to switch branches in Git and not commit local code?

1. Introduction to branches

In Git, branching is a very important concept. It is the core of version control and is used to isolate and manage different codes. In Git, a branch is actually a pointer to a commit, and the commit pointed to by this pointer is the "head" of the branch. When we operate on a branch, we are actually operating on the commit pointed to by the branch and the "commit chain" related to it.

2. Switch branches

In Git, switching branches is very simple, just use the "git checkout" command. For example, if we want to switch to the branch named "dev", we only need to enter in the command line:

$ git checkout dev

In this way, we can start working on the "dev" branch in the current working directory. When we need to go back to the main branch, we only need to run the git checkout command again:

$ git checkout master

However, when switching branches, be careful not to forget to commit the code of the current branch first, otherwise, the code of the current branch may be lost.

3. Switch branches without committing local code

However, in some cases, we do not want to commit the code of the current branch when switching branches. For example, in a very complex project, we may need to make some modifications on a branch and test them for a period of time, but we do not want to commit these modifications to the remote warehouse. At this time, we need to not submit the local code of the current branch when switching branches.

In Git, we can use the "stash" command to temporarily save the modifications of the current branch and then switch branches. The specific steps are as follows:

1. On the current branch, use the stash command to save the modifications of the current branch:

$ git stash save "Change comment here"

In this way, the modifications of the current branch are saved in a temporary in "Archives".

2. Use the git checkout command to switch to the target branch:

$ git checkout dev

3. Make the required modifications on the target branch.
4. When you need to return to the original branch, you only need to perform the following two operations:

① Switch back to the original branch:

$ git checkout master

② Restore the temporary archive Modification:

$ git stash apply

This way, you can switch branches without committing local modifications to the current branch.

4. Summary

In Git, branch switching is a very common operation. However, when switching branches, we should pay attention to submitting the local code of the current branch to avoid data loss. In some cases, we may need to switch branches without committing local code. At this time, we can use the stash command to save the modifications of the current branch to a temporary archive, and restore the local modifications after switching branches. This way, we can switch branches without losing local modifications.
