Commits and history

Make small commits with clear messages, and go back in time when needed.

Why it matters

When code that worked yesterday breaks today, git log and git restore are how a developer finds and brings back the last good version.

Inside the module.

4 lessons in order, about 60 minutes in all, then a short test. Learners go at their own pace; the minutes are a guide, not a timetable.

Draft outline · in review

  1. Lesson 1: init, add and commit

    Start a repository, stage changes with git add and save them with git commit.

    Worked example15 min, from minute 0

  2. Lesson 2: Small commits, clear messages

    Commit one change at a time with a message that says why.

    Practice15 min, from minute 15

  3. Lesson 3: Reading the history

    Use git log, git show and git diff to see what changed and when.

    Explain15 min, from minute 30

  4. Lesson 4: Going back in time

    Use git restore and git revert to undo mistakes safely.

    Practice15 min, from minute 45

  5. End-of-module test

    Make small commits with clear messages, read the history and restore an earlier version of a file.

    Mastered at 85% or more. Retake it until you pass; nothing is lost, and each try gives feedback.

    Already know it? A Challenge Test (planned) clears the whole module: 90% overall, no objective below 75%.

Practicalities

Draft outline · in review

  • Built to run offline

    Planned to run on the Lantern's own computer, with no internet needed.

  • Languages

    Planned first in English; every module aims to reach all of the Lantern's languages.

Try a question.

One question from the module, as a learner would meet it. Have a go, then open the worked solution a step at a time.

You edited app.py and broke it. You have not staged or committed the change. Which command throws away your edits and brings back the last committed version of app.py?

Show levels in

Level mappings are approximate. A qualified teacher or lecturer in each country must check them before they appear in the app. Levels 13–18 describe the content, not the learner: “Level 15” means material usually taught in a second-year university course, whoever chooses to learn it.

Alignments

  • Aligned to CS2023partial · in reviewCS2023 Software Engineering: version control (descriptive ref)

Alignment in review until a qualified teacher or lecturer checks it. No exam body, university or vendor endorses us; learners still sit the real exam. University-level modules give knowledge, not university credit.

Challenge Test

Planned: a Challenge Test to prove you know it and skip it. Pass at 90% overall, with no objective below 75%.
