changes allows beginners with minimal programming experience to use version control. Version control is a framework that saves previous versions of your work as you develop your projects (Like ‘Track changes’ in MS Word). You can then easily look at previous versions, merge changes, and collaborate with others, but without the headache!
changes uses git under the hood. Git is a popular version control system used by projects such as Android and ggplot2. Don’t worry, you don’t need to know any git to use changes!
Here’s a quick demo of how to use changes:
First, we need to create a new project (we only need to do this the first time we work with the project).
We can tell the repository if there are files (e.g. large data output files) we don’t want to keep records of
and we can always change our minds later.
With the project set up, we can work on our project as normal.
We can then see which files have changed and make a record of the project, with a message to say what we did
Now we can keep working on and adding files in this folder, and recording our changes regularly with
It’s easy to forget to record, so changes will automatically remind us if we have unrecorded changes and it’s been some time since we last used changes. By default we’ll be reminded after 60 minutes, but we can change that:
If we make a change we don’t want to keep or record, we can undo it and go back to our last record
We can look at all the records we’ve made so far
and go back in time to recover the project at any one of those records - all of the files will be changed back to how they were at the time of that record
but don’t worry, we can always go back to the future to recover our subsequent work.
If we want to start again from a previous record, we can bring that record to the end of our timeline. changes will change all of the files to how they were at the time of the record, but all the work we recorded since then will still be stored, just in case we need it later.
