In the following tutorial you can practise the basics of working with version control. In this case GIT.
There are a few main principles you have to understand.
- repositories (a set of files managed by GIT, local or remote)
- remote repository (the repostiroy where you work on together)
- commit in a repository (creating change-sets)
- pulling commits from a repository
- pushing commits to a repository
note: Please also check: https://www.atlassian.com/git/tutorials/learn-git-with-bitbucket-cloud. You can replace bitbucket cloud with Github.
When you changed a file in your repository GIT noticed it and will ask you what to do with it.
So for example:
You are writing a script: import.R.
- Create a new file
- Change the file
- Save the file
- Give the file a name
- Check in the commit-box what changes you made
When you changed a fileset that is of use for other people to or you are just finished with it you can commit it into the repository.
note: Once you commit a fileset you have need to push it as well to get it into the remote repository.
- Click on "commit"
- Select the files you want to commit
- Enter the commit message
- Click on commit and you get a commit id which you can also find on https://github.com/lifecycle-project/analysis-tutorials.git
To persits the change you made on a remote repository you to synchrnise (pull) with the remote repository and store your local changes on the remote repository (push).
- Pull from remote
- Result of pull
- Push local changes to remote repository
- Check push result
When you have performed these steps the remote is in sync with your local repository,
note: The default workflow is to start each time you work in a repository with a pull from the remote repository. This is ncessary because other contributors can have changes pushed into the remote while your not working on it. There is one exception when you start a new project than you start with an "Initial commit".
