Git (and Redmine)

Notes

• the first section (first setup) and the concrete URLs are specific to Redmine
• the rest would be the same with any other remote machine which offers storing of git repositiories (e.g. GitHub or BitBucket)

First setup on Redmine

• Login and set a new password
  • go to https://redmine.ms.mff.cuni.cz/login
  • log in with your username (name.surname) and password
  • your first password is temporary -- go to "My account" -- "Change password" and set a new password (and remember it)
• Setup the repository for this course
  • go to https://redmine.ms.mff.cuni.cz/projects/undergrads
  • click on your subproject
  • Settings -- unselect "Public" -- Save
  • Settings -- Members -- New member
    • add "Rudolf Rosa" and "Zdenek Zabokrtsky" as "Reporters"
  • Settings -- Repositories -- New repository
    • SCM: Gitolite
    • Identifier: 2017-npfl092

Filling your new repository -- VERSION A (git add remote)

• create a local repository
  • cd
  • mkdir 2017-npfl092
  • cd 2017-npfl092
  • git init
• add a README file
  • echo 'This is my repository for NPFL092.' > README
  • git status
  • git add README
  • git status
• commit the changes locally
  • git commit -m'adding README'
  • git status
• push your repository to Redmine
  • git remote add origin https://name.surname@redmine.ms.mff.cuni.cz/undergrads/surname/2017-npfl092.git
  • git push -u origin master
  • you will need to enter your Redmine password
  • you can also use SSH instead of HTTPS, which saves you some password typing, but requires you to set up SSH keys
  • git status

Filling your new repository -- VERSION B (git clone)

• clone your repository
  • cd
  • git clone https://name.surname@redmine.ms.mff.cuni.cz/undergrads/surname/2017-npfl092.git
  • cd 2017-npfl092
  • Note: you can also use SSH instead of HTTPS, which saves you some password typing, but requires you to set up SSH keys.
• add a README file
  • echo 'This is my repository for NPFL092.' > README
  • git status
  • git add README
  • git status
• commit the changes locally
  • git commit -m'adding README'
  • git status
• push changes to Redmine
  • git push
  • you will need to enter your Redmine password
  • git status

Synchronizing changes

• make a new clone of the repository at a different place
  • cd; mkdir new_clone_of_repo; cd new_clone_of repo
  • git clone https://name.surname@redmine.ms.mff.cuni.cz/undergrads/surname/2017-npfl092.git
  • cd 2017-npfl092
• make some changes here, stage them, commit them locally, and push them to Redmine
  • echo 'This repo will contain my homework.' >> README
  • git add README
  • git commit -m'adding more info'
  • git push
• go back to your first local repo and get the new changes from Redmine
  • cd ~/2017-npfl092
  • cat README
  • git pull
  • cat README

Regular working with your repo

• go to a directory containing a clone of your repository (or make a new one with git clone if on a different computer)
• synchronize your local repo with the repo on Redmine with git pull
• do any changes to the files, create new files, etc.
• view the changes with git status (and with git diff to see changes inside files)
• stage new/changed files that you want to become part of the repo with git add (untracked files are ignored by git)
• create a new snapshot in your local repo with git commit
• synchronize the repo on Redmine with your local repo with git push
