Git Demo
What is a version control system?
- Version control is a piece of software which allows you to record and preserve the history of changes made to directories and files.
- If you mess things up, you can retrieve an earlier version of your project.
Have you been here before?
- Save a copy elsewhere?
- Save with a different name?
- How do you name different versions?
- What's different between them?
- Many copies of nearly-identical but critically different files
Storing versions without VCS
Why use version control?
To store versions properly
- VCS treats files as one project - one current version on disk, previous versions and variations saved in the repository
- VCS starts with a base version of the project, and only saves the subsequent changes you make
- In order to save a new revision, a commit message is required, which explains why the changes were made
Changes are saved sequentially
Different versions can be saved
Multiple versions can be merged
- Restore previous versions
- Understand what happened
- Backup
- Collaboration
Why use version control?
- Track changes to MATLAB files for converting units
- Show history of project
- Show differences between versions
- Work on different versions in branches
- Local repo and remote repo
Demo overview
Caveat
- This is a demo, not a tutorial
- Objective is to appreciate the utility of version control
