Submodules vs subtrees comparison in Git - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the command to add a Git submodule.

Git

git submodule [1] https://github.com/example/lib.git

Drag options to blanks, or click blank then click option'

Aadd

Bclone

Cinit

Dupdate

💡 Hint

Common Mistakes

Using 'clone' instead of 'add' causes an error.

Using 'init' only initializes existing submodules.

The git submodule add command adds a new submodule to your repository.

2fill in blank

medium

Complete the command to pull changes for all submodules.

Git

git submodule [1] --recursive

Drag options to blanks, or click blank then click option'

Aclone

Badd

Cinit

Dupdate

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'init' only initializes submodules but does not update them.

Using 'clone' is not valid here.

The git submodule update --recursive command fetches and checks out the correct commits for all submodules.

3fill in blank

hard

Fix the error in the command to add a subtree at prefix 'lib'.

Git

git subtree [1] --prefix=lib https://github.com/example/lib.git main

Drag options to blanks, or click blank then click option'

Aclone

Bpull

Cadd

Dinit

💡 Hint

Common Mistakes

Using 'pull' instead of 'add' causes errors.

Using 'clone' is not a valid subtree command.

The correct command to add a subtree is git subtree add.

4fill in blank

hard

Fill both blanks to complete the command that updates a subtree from remote 'origin' branch 'main'.

Git

git subtree [1] --prefix=lib [2] main

Drag options to blanks, or click blank then click option'

Bpush

Corigin

Dadd

💡 Hint

Common Mistakes

Swapping pull and push causes wrong behavior.

Using 'add' instead of 'pull' does not update the subtree.

The command git subtree pull --prefix=lib origin main updates the subtree from the remote repository.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps submodule names to their paths if they are initialized.

Git

{ [1]: [2] for [3] in submodules if submodules[[3]]['initialized'] }

Drag options to blanks, or click blank then click option'

Aname

Bsubmodules[name]['path']

Dsubmodules

Attempts:

3 left

💡 Hint

Common Mistakes

Using the wrong variable name causes errors.

Not filtering initialized submodules includes unwanted entries.

This comprehension creates a dictionary with submodule names as keys and their paths as values, filtering only initialized submodules.
