In order to modify the commit messages we need to work with the prepare-commit-msg hook. We’re going to utilise a Git hook to check a branch name and automatically prefix commit messages with the current issue number. git/hooks directory and the file is executable it will run at the relevant point in the Git processes. If Git finds a file named after one of its hooks in the. sample, you can remove this for them to start working or create a new file with just the hook name. These sample scripts won’t currently do anything as they are suffixed with. If you take a look at a Git repository you’ve cloned or initiated you should find a few sample scripts in the. They provide a means of interacting with the default Git behaviour at various stages and add in custom functionality. Git hooks are scripts that reside within a repository’s. Thankfully this is straightforward to do by implementing one of the numerous Git hooks that exist. It’s a new process to me from the way I normally branch and commit I wanted to configure Git so that whenever I make a commit the branch name is checked and the issue number automatically prefixed to the commit message. If you’re not sure, ask your senior devs what they prefer.Recently I’ve been working with a Git workflow that requires a specific format for branch names and commit messages: branch names are formatted to contain an issue number and each commit message is prefixed with the issue number it relates to.
#Change git commit message code#
A good rule of thumb is if your fix isn’t changing the code behavior (looking at you, whitespace cleanup), git -amend is a good option. In conclusion: git -amend is very very useful! It can help you keep your commit history clean, so that when one of your colleagues (or future you) is referring to the commit history, it’s not cluttered up with simple fixes for things like typos and linter cleanup. Next all that’s left is pushing your new changes up. It will not change the message associated with the commit because we have not used the -m flag. This command will change the files in your last commit. You can do this by using the –no-edit flag: Once you have made the changes to a repository, you are ready to amend your commit. If you want to remove a file from a commit, you can use git rm: To change the files in a commit, first add the files you want to be included in your commit: We can use the git commit –amend command to get out of this bind and fix the issue. Without it, you will be fired immediately. Say that your last commit is missing a crucial file. Git commit -amend -m “this fixes the previous oopsies” If you’d like to use the -m flag here’s an example of what that would look like. Save and exit the text editor and your change will be made. If you do, an interactive text editor will be opened up in which you can replace the message from your older commit. You can use this command without the -m flag. The syntax for the amend command is as follows: Git has a solution for you: the git commit –amend command.
The old commit is replaced with a new commit which means that when you amend your old commit it will no longer be visible in the project history.ĭid you forget to include something in your last commit message?ĭid you add something into your commit message that is not relevant? You can change your log message and the files that appear in the commit.
The git commit –amend command lets you modify your last commit.
