How to fetch all the tags from a remote repository in git

To fetch all the tags from a remote repository, you can use the git fetch command with the --tags option. Here’s how you do it:

git fetch --tags

This command will fetch all tags from the remote repository, as well as the commits they point to. After fetching, the tags will be available in your local repository.

If you want to fetch both the tags and the branches updates, you can use:

git fetch --all

This will fetch all branches and tags from all remotes configured for your repository. However, if you only want to update your tags to match the remote repository (which might include deleting local tags that have been removed on the remote), you can use:

git fetch --prune --tags

The --prune option will delete any local remote-tracking references that no longer exist on the remote.

Remember that fetching tags will not automatically merge any changes into your current working branch. If a tag points to commit(s) that are not in your current branch’s history, you will need to merge or rebase to include those changes in your working branch.

Solved the Issue of substring not matching

In my project, I find a wired problem, we added More to an attribute string on swift, and set the different attribute for the last word More, but some times the word selected is not the More, but one letter less.

After debug the program, and find that it was caused by the string has html tag p on the string, and we removed part of the string in the end, and added More to the string, and add the string to NSAttributeString, and I find that the string with <p> in the beginning will add an \n to the end of the string.

I used the NSAttributeString.string method to get the pure string, and find that the end has \n.


The solution that I find is get the pure string before update data, so the html tag will be removed, and the string is correct right now.
