    MpdRoot archive
BmnRoot archive
SpdRoot archive
  2. Add your Git username and set your email

    3. It is important to configure your Git username and email address, since every Git commit will use this information to identify you as the author.

    On your shell, type the following command to add your username:

    git config --global user.name "YOUR_USERNAME"

    To set your email address, type the following command:

    git config --global user.email "your_email_address@example.com"

    To view the information that you entered, along with other global options, type:

    git config --global --list
  3. To get a GIT repository use this command

    git clone git@git.jinr.ru:nica/mpdroot.git

    for bmnroot:

    git clone git@git.jinr.ru:nica/bmnroot.git

    for spdroot:

    git clone git@git.jinr.ru:nica/spdroot.git
  4. To download the latest changes in the project
    5. git pull
  5. To view all branches in the project
    6. git branch -r
  6. To work on an existing branch

    7. To switch to an existing branch, so you can work on it:

    git checkout NAME-OF-BRANCH
  7. To create a new branch and start working with it

    8. Please use names for branches in accordance with the task for common understanding, like: feature-new-geometry or bugfix-old-problem. Spaces won’t be recognized in the branch name, so you will need to use a hyphen or underscore.

    git checkout -b NAME-OF-BRANCH
  8. To add new file or folder in your branch
    9. git add NAME-OF-FILE
  9. To add all new files or folders in your branch
    10. git add .

    11. It’s important to be aware of what’s happening and the status of your changes. When you add, change, or delete files/folders, Git knows about it. To check the status of your changes:

    git status
  11. View differences

    12. To view the differences between your local, unstaged changes and the repository versions that you cloned or pulled, type:

    git diff
  12. To save all changes that you made in local machine GIT repository
    13. git commit -am "Some comments add here"
  13. To save the changes in remote server machine GIT repository (origin branch)
    14. git push origin NAME-OF-BRANCH
  14. If you want merge NAME-OF-BRANCH with protected dev branch create merge request on GitLab site for MpdRoot or BmnRoot. Then if your branch has passed the testing without errors, you can merge branches by clicking the button on the site.
