Git + Python
Automate Git from Python — diffs, hooks, release tags, and repo housekeeping.
Find the Commit That Introduced a String in Git History Using Python
Use git log -S with Python subprocess to find the earliest commit that introduced a specific string across your repository history.
import subprocess
import sys
def find_introducing_commit(repo_path: str, search_string: str, file_glob: str = "*") -> str:
"""Find the first commit that introduced a given string in a git repository."""
result = subprocess.run(
["git", "-C", repo_path, "log", "--all", "--oneline", "-S", search_string…How to Push Git Tags to a Remote with Python
Push specified git tags (or all tags) to a remote repository using Python's subprocess module with error handling.
import subprocess
import sys
def push_tags_to_remote(remote: str = "origin", tags: list[str] | None = None) -> None:
"""
Push git tags to a remote repository.
If no tags are given, push all local tags.
"""
if tags:
subprocess.run(["git", "push", remote, *tags], check=True)

…Merge branch no ff mock in Python
Simulate a Git non-fast-forward merge in Python, producing a synthetic merge commit log for branches with differing SHAs.

self.commit_log = []
self.merged = False
def simulate_merge(self):
