About

Git is the industry-standard distributed version control system, essentially a directed acyclic graph (DAG) of filesystem snapshots. While powerful, its syntax (CLI) is often non-intuitive, leading to the infamous "xkcd strategy" (delete repo and clone again). This tool solves the Cognitive Load problem by mapping intent to syntax.

Accuracy in Git is critical. A misplaced force push or an accidental hard reset can obliterate hours of work or corrupt shared history. This utility acts as a semantic bridge, offering context-aware command generation and visual safety indicators for destructive operations.

Formulas

Git operations can be modeled using Set Theory and Graph Theory. A repository R is a set of commit objects connected by directed edges.

1. Merge Operation (Union):
A merge creates a new commit C_m that has two parents.

{

C_m ← A ∪ Bwhere A, B are branch tips

2. Rebase (Linearization):
Rebase replays commits C_i from the source branch onto the target base B_t.

n∑i=1 apply(C_i, B_t) &implies; New History

3. Diff (Symmetric Difference):
Showing changes between two references.

Diff = (A ∖ B) ∪ (B ∖ A)

Frequently Asked Questions

Use "git reflog". Git keeps a log of every HEAD movement for 30-90 days locally. Find the hash index (e.g., HEAD@{5}) and check it out or reset to it.

"git fetch" downloads data from the remote repository to your local machine but does not modify your working files. "git pull" performs a "git fetch" followed immediately by a "git merge", which updates your files.

Adding them to .gitignore isn't enough. You must remove them from the index using "git rm --cached " to stop tracking them while keeping the local file intact.

It means your HEAD pointer is referencing a specific commit hash directly, rather than a branch name. Any new commits made here will be orphaned (lost) if you switch away, unless you create a new branch to contain them.
