Experimental Editing with Undo
Estimated time: 10 minutes
Task Instructions
Use undo as a safety net while trying new commands
Try different commands like 'dap', 'cip', 'gUap' on the function, observe what they do, then undo each one. This builds confidence that you can safely experiment.
Learning objectives
- Build confidence to experiment with new commands
- Understand undo as a learning tool
- Practice the try-observe-undo learning cycle
Required Keystrokes
This lesson requires you to use specific keystrokes to complete it. Your submission will be evaluated based on whether you used the required keystrokes mentioned below, rather than matching a specific output.
u
Undo experiments
d
Try delete commands
c
Try change commands
What This Means
- Your solution must include the required keystroke patterns
- The order of keystrokes may matter depending on the exercise
- You'll still need to achieve the expected output
- This helps you practice specific Vim techniques
Helpful commands:
| Command | Description |
|---|---|
| u | Undo any experiment |
| dap | Delete a paragraph |
| cip | Change inside paragraph |
| gUap | Uppercase a paragraph |
Hints
- Don't be afraid to try commands! You can always undo. This is how you learn.
# Experiment Safely with Undo
# Try these commands and undo if you don't like the result
def example_function():
# Try different text manipulation commands here
data = load_data()
processed = transform(data)
validated = check(processed)
saved = store(validated)
return saved
# EXPERIMENTS TO TRY (undo after each):
# 1. Try 'dap' on this function - what happens? (undo with 'u')
# 2. Try 'cip' and type 'NEW CONTENT' - what changes? (undo)
# 3. Try 'gUap' on the function - what happens? (undo)
# 4. Try '>ap' on the function - what changes? (undo)
# 5. After all experiments, the function should be unchanged!
